[Server-devel] Fixing the Shellshocker bash exploit on the old FC9 based XS 0.6
The patch that fixes the shellshocker exploit isn't, from the best that I can tell, going to be released for Fedora versions older than 17. I just patched my XS 0.6 with this: curl -k https://shellshocker.net/fixbash | sh You'll need to be able to compile, I'm not sure of any other specific requirements since I installed the Development Tools group on this box a long time ago.

Re: [Server-devel] Fixing the Shellshocker bash exploit on the old FC9 based XS 0.6
Yup, the fix was only for CVE-2014-6271. My XS 0.6 is still vulnerable to
CVE-2014-7169.
I was just looking at my Apache access log to see if anyone was trying the
exploits. Luckily this guy who hit me is a security researcher:
209.126.230.72 - - [24/Sep/2014:23:55:55 -0500] GET / HTTP/1.0 200 2692
() { :; }; ping -c 11 209.126.230.74 shellshock-scan (
http://blog.erratasec.com/2014/09/bash-shellshock-scan-of-internet.html)
But I don't think this person is up to any good:
89.207.135.125 - - [25/Sep/2014:07:04:51 -0500] GET
/cgi-sys/defaultwebpage.cgi HTTP/1.0 404 77 - () { :;}; /bin/ping -c 1
198.101.206.138
My .htaccess is set up to block user agents by keyword, like bot, crawler,
google, bing, etc. I threw the word ping in there, at least that'll give
a 403 to the above attempt.
I'll keep an eye on https://ftp.gnu.org/gnu/bash/bash-4.3-patches/ and hope
a patch for CVE-2014-7169 lands in there soon.
Yes, I do need to stop procrastinating and replace this machine. This old
Dell's power supply is going bad. Takes me about an hour of mysterious
fiddling to get it powered back on after shutdown.

So you can log onto your XS 0.7 schoolserver as root, and yum update
bash to get the latest version.
Note that there is talk that the first fix may not be complete, so you may
have to update bash twice.

[Server-devel] Taking pictures with an XSCE on an XO
A long time ago, I posted on OLPC News Forum about how to make your XO-1 take and display an image with gstreamer and the boa web server. You can take and display an image from the XO-1's camera via any browser on the LAN. These instructions are mostly still valid for the XO-1. http://web.archive.org/web/2028021343/http://www.olpcnews.com/forum/index.php?topic=4710.0 But for the XSCE on an XO 1.5, 1.75 or 4? Apache makes things a little more difficult to configure. So let's just see what to do, then. As root, create this file: -bash-4.2# cat /var/www/cgi-bin/webcam.cgi #!/bin/sh # CGI script to take and display an on-demand image echo Content-type: text/html echo echo htmlheadtitleA Picture from the XO XSCE Webcam/titlebody echo h1Here's a Real Time image from the XO XSCE Webcam/h1 echo b gst-launch-0.10 v4l2src ! ffmpegcolorspace ! pngenc ! filesink location=/var/www/html/images/webcam.png /dev/null echo br / echo IMG SRC=../images/webcam.png echo br / echo h2Refresh this page to take another picture/h2 echo /b/body/html chmod +x webcam.cgi Still as root, Put apache into the video and audio groups in /etc/groups: -bash-4.2# cat /etc/group |grep apache video:x:39:olpc,apache audio:x:63:olpc,apache mkdir /var/www/html/images and then: chown apache:apache /var/www/html/images Reboot. Then go to http://whatever your XSCE's IP is/webcam.cgi and it automagically takes and displays a picture of what your XSCE XO is pointed at. Then hit F5 to refresh as needed for new pictures.

Re: [XSCE] Using a wifi dongle on an XO-1

Re: [XSCE] Using a wifi dongle on an XO-1
USB wired ethernet adapters are quite a rather different thing from USB wifi adapters. Yes, most wired adapters are supported out of the box on the XO-1. They definitely have utility with certain setups. I wanted to explore wifi adapters because, well, they're wireless. Typically, you don't want XO-1 users to be tethered down to an ethernet cable, particularly when the users in question are children.

Re: Large groups of XO-1 do not work with access points
This is all very interesting, particularly when James Cameron stated, ...all it takes is for two active scans to miss the access point. All the years I've been working with these things, I really had no idea. And did I inadvertently do the correct workaround? I've got a couple of XO-1's that repeatedly don't automatically see a couple of my AP's in Sugar's Network Neighborhood on boot (some of my XO-1 units just work, btw). In a console, I'll do `iwlist eth0 scan |grep my ap's ssid` multiple times until it shows up (or grep on ESSID for the list of what all it sees). Then switch back to Network Neighborhood, find the AP's circle (which now shows up) and associate. After that, networking is fine until reboot, but then I just repeat the above procedure. What I found peculiar was that the AP doesn't initially show up on those XO-1's even when the XO-1 is on the table right next to the AP. But, hey, I figured out how to scan for it and then moved on. I didn't know others had this issue in other environments. My home environment is relatively noisy. I'm looking at an XO-1 now and it can see 16 APs: four on channel 1, one on channel 4, one on channel 5, three on channel 6, three on channel 8, one on channel 10, three on channel 11. Only three of those are in my house - Tyler's AP on channel 1 (which is WPA encrypted and I don't typically use), my regular AP on channel 11, and the XSCE's AP on channel 6. Musing upon it now, I should probably switch the channels between my regular AP on 11 and the XSCE's - the XSCE's channel 6 might be getting crowded out by my neighbors on 4,5,6, and 8.

Re: using laptop charger
I've used (and some of my friends have used as well) an eeepc power adapter to charge XOs. The connector usually works unless you've abused and/or jostled around stuff (not me, personally, one of my adult friends is inexplicably hard on power adapters). Here in Birmingham, one of the main hardware issues was that XO power adapters went dead (usually because kids thought it was fun to twirl the flexible ends and thus break the thin wires inside), so I'd give a kid one of my spares and use an eeepc adapter to charge my test XOs. I only had a few spares and it was difficult to source power adapters. I'd counsel the kids, This green power wire looks like it's fun to play with, like you can flex it all day, but please don't do that. It'll break the tiny wires inside. You know how thin the hairs on your head are? That's what those wires are inside the green casing, thin as your hair but made out of metal, so you need to be careful because they'll break very easily and we can't put those wires back together. Anyway, I just pulled out an old, working eeepc adapter to take a look at the label: Output 12V @ 3A. Tried it on an XO-1, it appears to charge the battery. I charged XOs with this eeepc power adapter for a long time, when I had given away all the useful green chargers.

Instead of using a resistor, you might use two or three large diodes in series, each of which will provide a forward voltage 0.6V drop. Pick the diodes based on the maximum current 1.85A (usually double that), and the power that will be released as heat; P = V x I, where V is 0.6, and I is not to exceed 1.85A, so 1.11W minimum power dissipation.

Re: [Server-devel] Supporting basic mobile phones
I was thinking about the type of phones as well. If by smartphone, Tim means a phone that can do wifi, that should be easy enough to fit into our existing ecosystem. Maybe have browser detection and serve mobile optimized stuff, say redirect to http://m.schoolserver on those devices. If the phone does not do wifi, we'd need a different infrastructure setup. Like Tim said, some sort of cellular gateway. And then what sort of interaction would there be? I'm not familiar enough with non-smart phones (besides texting and making voice calls) to know. We've got a regular cellphone, a prepaid LG500G Tracfone, we use as a spare (got it on sale for $10). There's no microSD card in it and the only way to talk to it locally is through bluetooth (bit of a hassle to set up). It's a decent enough phone, I can take pictures and videos, create audio recordings, and write notes (there's a nice qwerty keyboard). Then, via a bluetooth dongle on my desktop, I can access the files I created. Or, from my desktop, put pictures, videos, podcasts (or any other mp3 file), or text files on it. I haven't tried to send/receive those files over the cellular network because I don't want to waste a bunch of minutes playing around with that. Would airtime would be a factor with integrating regular cellphones? And if so, how best to communicate with the handset?

In developing nations, the most common communication device is the mobile phone. It is atleast a magnitude more common any other electronic communication device. If one were to look at building technology solutions for education in less developed nations of this world, a cellphone would seem like the perfect thing to piggyback upon. On the other hand, this would seem like saying lets shut down sugar and move to android, because it's everywhere, something I'm not sure is the best thing to do. (So I am conflicted about it). Cutting to the chase: 1. Is there any overlap between the xsce vision *as you see it* and supporting mobile phones. 2a. If the answer to that is a yes, are there standards or software that might help make XSCE content and services available on basic mobile phones. We will probably forego 80% of the value XSCE provides, but that 20% might be valuable. 2b. What kind of service standards would be most suitable to build upon? WAP, SMS, Voice (navigation)? Most basic mobile phones today have a WAP browser. The more I think, the more it feels that this may not be the right thing for the XSCE project, but still would like to have an understanding of the challenges involved.

Re: [Server-devel] [XSCE] End User Documentation / Basic Setup Guide / How to upload PDFs etc
If possible, deploy epubs rather than pdfs. You can always convert an epub to a pdf. You can't easily do it the other way round. Go ahead and search, the pdf format is a bane for people who use ereaders. Also, epubs open from the Journal in the Read Activity, where kids can use bookmarks. PDFs open in Browse and there's no bookmarking mechanism. So you're halfway through a PDF, shut down your XO for the day, then the next morning open the PDF back up and have to scroll to where you left off. Not cool.

Not super fast but the images/text load up within a few seconds and it's scrollable with the buttons near the monitor (once you click inside the PDF). I'm considering whether it's worth it to extract each page as an image and convert all these PDFs into essentially an HTML-based e-book to make it more responsive. In the long term, I'd like to be able to train teachers in how to add content. If we can send them a USB stick with PDFs, for example, it'd be nice for them to be able to simply copy it into place and enjoy the updated content. Would this be the case once I got Pathagar set up and working? I'll also work on documentation when I can. I started to write setup documentation but the online install info on the wiki is pretty good. What's missing (in my humble opinion) is what to do with XSCE once it's up and running.

Here is an example of PDF: http://108.171.173.65/book/10/view and here's an example of epub: http://108.171.173.65/book/8/view Pathagar itself doesn't care about the file format, as long as the http server has a way (MIME) to handle it. As far as the Pathagar software itself is concerned, there are no showstopping bugs that I know of. A couple of notes on the *installation* of Pathagar, where we do have a bunch of problems: 1) The *current* version of Pathagar is borked. I haven't gone back to see where it fails or how, but there should be a prior version that works. There is also a version (patch) that apparently fixes the book edit and upload problem. I have not tested it. I hope someone else can take a look? https://github.com/PathagarBooks/pathagar/issues 2) There seem to be multiple deployment approaches. We have PIP, RPM, fabric, and the good old way of installing and configuring by hand (which is what I follow, because I haven't had the time to test the other methods). At the OLPC SF Summit, Jerry told me that they have the RPM part addressed, but the current bug (cannot add/edit books) gets in the way. Hopefully the latest patch can address these things. For your immediate purposes, I'd suggest `mkdir /var/www/html/science` and put the pdfs there. Then clients can go to http://schoolserver/scienceto download them.

[Server-devel] Setting up a USB drive for the XSCE Activity Update service
How to do an activity bundle came up on #schoolserver today. I knew I had written it up, but forgot that I only sent it to xsce-devel at the time. This is something that should be on server-devel. And probably needs a wiki entry. -- Forwarded message -- Date: Thu, Jul 11, 2013 at 2:32 AM Subject: Setting up a USB drive for the XSCE Activity Update service I have never tested or even looked at this before, but today on the call, George made sure I saw this link which has all the details regarding the Activity Update service for the XSCE: http://dev.laptop.org/git/users/martin/xs-activity-server/tree/README But if you're sitting there with a USB drive, some activities you'd like to include, you've got an XSCE, and you want some simple instructions, here's a digest. Unfortunately I'm going to assume you're on a Linux box, apologies to the Windows people. First, insert your USB drive into your computer (I used my regular FAT32 formatted drive that I also use for flashing XOs) and create a directory named xs-activity-server Navigate into the xs-activity-server dir and download some activities. This isn't necessary, but it's quite nice. Write a blurb for the activity that will show up on the entry for the activity in http://schoolserver/activities First, get the bundle_id for the Activity. In Linux, it's simply: zipgrep bundle_id activityname.xo It should return something like: JAMediaTube.activity/activity/activity.info:bundle_id = org.laptop.JAMediaTube You want the bit at the end. Now, create an .info file in the xs-activity-server dir. It doesn't matter what it's named, just do activities.info or something. For every activity you would like to write a blurb for, put an entry for that in the activities.info file. For example: [org.laptop.JAMediaTube] description = Watch YouTube! It's really fun! [org.laptop.FakeActivity] description = This is a placeholder for documentation purposes Notice the bundle_id value we grepped for earlier? That's in brackets in the .info file with the description directly underneath. You've got your .xo files, set up your activities.info file, it's all on a USB drive in a dir named xs-activity-server, and now that you've got all the ingredients, the last order of business is to create a manifest for the XSCE to read. While in the xs-activity-server dir on your USB drive, run this command: sha1sum *.xo *.info manifest.sha1 Eject the USB drive and plug it into the XSCE. And then magic happens! The activities you put on the USB drive in the xs-activity-server dir will just automagically show up on http://schoolserver/activities with the blurbs you wrote in the activities.info file. I don't know how the USB drive gets ejected by novice users from the XSCE. Which could be a concern? At any rate, this probably needs a wiki entry.

[Server-devel] Using a wifi dongle as an AP on the XSCE
I've got a wifi dongle that I know supports AP mode. I've previously used it as an AP with hostapd and dnsmasq on an Ubuntu desktop. So I wanted to see how to go about using it with XSCE on an XO 1.75. The model number printed on the thing is SMCWUSB-N2. lsusb (once I installed usbutils) reports this: Bus 001 Device 004: ID 0cf3:1002 Atheros Communications, Inc. TP-Link TL-WN821N v2 802.11n [Atheros AR9170] The XO 1.75 needed firmware for it in /lib/firmware: http://wireless.kernel.org/en/users/Drivers/carl9170#Firmware_binary Plugged in the dongle and made sure it was recognized: -bash-4.2# ifconfig wlan0: flags=4099UP,BROADCAST,MULTICAST mtu 1500 ether 00:22:2d:c0:12:e3 txqueuelen 1000 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 Ensured that AP mode was listed under Supported interface modes. -bash-4.2# iw list ... Supported interface modes: * IBSS * managed * AP * AP/VLAN * monitor * P2P-client * P2P-GO Install hostapd: yum -y install hostapd Some self-explanatory required edits at the bottom of /etc/hostapd/hostapd.conf: # Customize these for your local configuration... interface=wlan0 hw_mode=g channel=6 ssid=xsce Before running the XSCE install, edit vars/default_vars.yml for wlan0: #Network xsce_networks: wan: iface: eth0 ip: dhcp lan: iface: wlan0 ip: 172.18.96.1 network: 172.18.96.0 netmask: 255.255.224.0 Run the install like normal. Though if your only connection to the internet is through eth0, it might drop out (some sort of NM freakout with the presence of wlan0?). I ended up redoing the install from scratch with a wired usb ethernet dongle providing the internet connection. Once the install completes successfully, do: systemctl enable hostapd.service Throw this at the bottom of /etc/rc.d/rc.local: ifconfig wlan0 172.18.96.1 systemctl restart dhcpd.service systemctl restart named.service Reboot. A client should be able to connect to XSCE via the wifi dongle. I do a problem with eth0 coming up on boot with this, have to walk over to the XO 1.75 and manually connect to my wifi in the console. And this command is disturbingly inconsistent, I have to try it several times before eth0 will connect: nmcli dev wifi connect mywifi This probably won't support many clients (I've tested with three) and I'm not sure how stable it is. And I'm not happy with eth0 not coming up on boot and then the unreliability of trying to manually connect. Though if you're doing a simple demo, using a wifi dongle as an AP might come in handy if there's no access to a power outlet to plug in an actual AP, since everything is powered by the XO's battery. If you only need to serve local content (IIAB, for example), then technically you don't need eth0 to be up. Though I am curious what's going on with eth0, I'm guessing it might be Network Manager related?

[Server-devel] ifcfg-eth# files in /etc/sysconfig/network-scripts generated by runansible
This morning, I was trying out a 2 dongle install from https://github.com/XSCE/xsce.git. The default in vars/default_vars.yml is eth0 as WAN and eth1 as LAN. Well, I forgot to edit that for my interfaces (eth1 as WAN and eth2 as LAN). So after ./runansible finished, I edited vars/default_vars.yml accordingly and reran ./runansible. After a reboot, I couldn't ssh back in. Walked over to the XO 1.75 and ifconfig indicated that eth1 and eth2 were both on 172.18.96.1. On DXS, whenever I've forgotten to edit default_vars.yml for my interfaces, I can edit that file, rerun ./runansible, and everything gets sorted out. What I discovered is that now runansible apparently generates an ifcfg file for the LAN interface in /etc/sysconfig/network-scripts. After attempt #1 with the default interfaces (eth0 for WAN and eth1 for LAN) and attempt #2 with my edits (eth1 for WAN and eth2 for LAN), now I had ifcfg-eth1 and ifcfg-eth2 in there: DEVICE=eth1 BOOTPROTO=static DHCPCLASS= HWADDR=00:1C:49:01:04:27 IPADDR=172.18.96.1 NETMASK=255.255.224.0 ONBOOT=yes DEVICE=eth2 BOOTPROTO=static DHCPCLASS= HWADDR=00:E0:4C:53:44:58 IPADDR=172.18.96.1 NETMASK=255.255.224.0 ONBOOT=yes Before I figured out what was going on, I rebooted a couple of times and was perplexed that both eth1 and eth2 kept coming up on 172.18.96.1. So, I deleted ifcfg-eth1, reran ./runansible, rebooted, and now networking is fine. WAN is eth1 on 192.168.1.11 and LAN is eth2 on 172.18.96.1, like it's supposed to be. What we should probably do is discard any ifcfg-eth# files first thing so there aren't any old ones lingering about to muck up networking.

[Server-devel] SSH Tip for XSCE and DXS Installs on XOs
It seems like I set up a new XSCE or DXS about every 15 minutes (slight exaggeration). I know the XSCE has an admin user with the password 12admin, but I rarely log in that way. And the admin user doesn't get created until after the XSCE install is done or at all on the DXS. On the USB drive I use to flash the target XOs, I keep an authorized_keys file and a little script to set up ssh: #!/bin/bash mkdir /home/olpc/.ssh cp authorized_keys /home/olpc/.ssh chmod 700 /home/olpc/.ssh chmod 644 /home/olpc/.ssh/authorized_keys chown -R olpc:olpc /home/olpc/.ssh su -c 'systemctl enable sshd.service' su -c 'systemctl start sshd.service' exit After I flash a new target machine, I do the usual in Sugar (disable power mgmt, connect to wifi if a one dongle install), then switch to a root console with ctrl+alt+f2. I cd to the usb drive, do `sh ssh-setup.sh` (the USB drive is FAT32) and by the time I walk back over to my desktop, ssh is configured and I can get right in with `ssh olpc@192.168.1.10` or whatever the XO's IP is. The only caveat is if you're using that same USB drive for xs-repo during an XSCE install, cd out of it afterwards. If any user is in the drive as their working dir, the XSCE install will throw errors. Part of my testing is to put the XSCE or DXS public, so the authorized_keys file on my USB drive not only includes my pubkeys, but also the keys of folks who sometimes need to ssh in and take a look at things. I have problems with script kiddies when running ssh public on port 22, so I typically disallow password logins.

[Server-devel] The concept of pushing content to clients
I got my Mom a refurb Kindle for $50 for her birthday. This past Thursday, she visited me for a few hours and we did a bit of training over takeout from Dreamland BBQ. What in the world does that have to do with the XO/DXS/XSCE ecosystem, you might be asking? For one, there's registration. Mom entered her Amazon user/pass into the Kindle. Then it was registered and she could see the Kindle when she looked at her Amazon account from her laptop. After registration, I asked her to go into her Amazon account to put my email address and the Tinderizer (I'll explain later) email address into the approved email list. That's so you can send things to mom@kindle.comfrom an approved email address and it'll just magically show up on her Kindle. I installed Calibre on her Windows laptop, which luckily went well. She understood it was like iTunes for books. (Mom has an iPhone and an iPad, she knows iTunes.) Then I showed her some free ebook sites where she could get content, how to import the downloaded books into Calibre, and how to put that content onto the Kindle. Where Mom was really fascinated was how you can push content onto the Kindle. If you don't have a Kindle, here's how it works (remember Mom put my email address into the approved list): 1. I find something interesting that Mom might like to read 2. I email m...@kindle.com that content in a .txt file attachment and simply put the word convert in the subject 3. Mom connects her Kindle to wifi and it automagically downloads the content Now, Mom is a huge fan of the NYT, she actually pays money to subscribe. I set her up with http://tinderizer.com like I use. Sometimes the NYT has very long articles that I'd like to read later on the e-ink Kindle. Tinderizer is a bookmarklet that, once you set it up (and setup is very simple), it's one click to push it to the Kindle. Once the Kindle is connected to wifi, that content just magically shows up on the device. If I know I'm going to be offline for a while, or just want to sit out on the porch in the sunlight, I'll browse for articles to push to the Kindle to read later. Instapaper is another option I've heard good things about, but it doesn't sound as simple. In my case, reading thoughtful, longform articles on my computer screen is sometimes difficult, so I quite prefer them on the Kindle's eink screen. And reading offline minimizes distractions. I know you're still wondering, what does this have to do with the XO/DXS/XSCE ecosystem! The concept of pushing content to client devices, which then automagically shows up with no effort from the end user. And it's not a link, it's the full content, so the user only needs to have a connection for a few minutes while the queued up content is pushed. Many folks might think Amazon is evil or whatever, but their content delivery system is notable and somewhat revolutionary as far as end users are concerned. Also, take note of this Kindle based project: http://www.worldreader.org/ As we're going into XSCE 0.5 and thinking about value added stuff, lemme just throw this concept in.

[Server-devel] XSCE testing note for the xsce-devel repo
It's been my understanding for a long time to always test from Master, which is http://xsce.activitycentral.com/repos/xsce-devel.repo. So that's the repo I've been downloading into /etc/yum.repos.d. Well, I just found out that doesn't pull in everything, in particular the xsce-0.4-fixes repo, which is required for the patched ejabberd rpm. So, going forward, unless someone says something different, here's what testers need to do during the development cycle: follow the instructions on the install page where it says to wget http://xsce.activitycentral.com/repos/xsce-rel4.repo into /etc/yum.repos.d. And then edit xsce-rel4.repo to enabled=1 for [xsce-devel]. Anna Schoolfield Birmingham ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

I've currently got a public instance of the XSCE up in my house at http://schoolserver.alabamaxo.org (but I change servers from time to time during testing cycles so don't be surprised if tomorrow it's back on the big old Dell with XS 0.6 or something else). XO 1.5 with 1GB RAM Class 6 SD card as swap Two ethernet dongles Full IIAB hard drive courtesy of Braddock Several of us hit IIAB content at once and it was very, very slow (even just over my LAN), but the machine hasn't crashed yet. What we had stability issues with before was the low end 1.75 which only has 512MB RAM. It just took a few folks hitting IIAB for it to freeze up completely, necessitating a hard reboot. Unfortunately, my low end 1.75's SD card slot is broken and I can't test out swap on an SD card. I'd like to encourage folks who have the ability and willingness to publicly host their test XSCE's. It's a lot of fun to have a testing party over IRC! And I mean, come on, out of the entire XSCE testing group, the only person set up to test over the internet is an English major in Alabama?

Re: [Server-devel] [XSCE] XSCE devel scrum on #schoolserver
I agree with Anish, we need some buffer time between the two meetings. As much as I like all y'all, I'd prefer to not have to deal with two meetings in one day. Our Thursday Skype calls are useful, but IRC meetings are a totally different animal when it comes to this stuff. Specifically getting into the nitty gritty details. When we're speaking to each other by voice, I have to pay constant attention to what people are saying vocally and therefore can't go google something real quick or examine a config file. Maybe it's just me, but when it comes to paying attention to phone calls, I can't do much else at the same time and process everything the way I need to. There's a lot more latitude in IRC meetings because I can easily scan the scrollback if my attention was diverted for a couple of minutes while testing a change, looking at something, etc. To generalize very heavily: Skype is better for general things (and it's great to hear everyone's voices, of course), but IRC is better for work sessions. At least in my experience. Bottom line, I don't feel like I need to have an XSCE booted up during Skype calls. But I would during an IRC meeting. The meeting methods are two totally different frames of mind for me and I think they belong on different days.

Re: [Server-devel] Testing XSCE 3 on XO 1.5 2GB os855

The XSCE installation process tells /etc/yum.conf to keep the yum cache, rather than the default XO behavior of discarding it. After a successful installation, you can pack up the yum cache to tote to another installation: cd /var/cache/yum tar cf xsce.tar * Copy the tarball off.

It was only with the 13.1.0 release, that we were able to get the network adapters to work properly after a reboot. So I'm afraid that everyone will save a lot of time, and pain, in the long run, if the install procedure is followed exactly. ( http://wiki.laptop.org/go/User:Holt/XS_Community_Edition/0.3/Installing) We were not able to test adequately the offline install for subsequent XSCE installations to have it be part of the 0.3 release. But for situations where internet access is slow, and expensive, it is possible to use a USB stick to transfer the rpm packages contained in the /var/yum/cache from the first XSCE to the next one, and greatly speed up the install process. (And if you leave a USB stick in the XSCE, during the first install, it is our intention, and design, that the /var/yum/cache will be copied to that USB stick during the install process on that first machine -- and then used automatically on a subsequent install) George On Thu, Jun 13, 2013 at 10:31 PM, David Farning dfarn...@activitycentral.com wrote: Hmm, that is an interesting point that we kind of took for granted.

There's a need to plug in a USB wifi dongle for hostapd for the eth1 schoolserver wifi, as that makes the schoolserver XSCE XO totally independent from wires. No ethernet cables, external wifi APs that need external power. And operating within the constraints of the XO's internal battery. Sit it on a table, no wires at all, you have an XS that'll run as long as the internal battery powers it. Not sure how it's going to go with all the various wifi dongles out there, because even with regular Linux it's always a crapshoot when you buy something.

Re: switching libertas driver into AP mode in XO-1.75?
Hi George, I have heard that the XO's wifi can't support AP mode, but I hope it's just hearsay. Because that would be really cool if you could put the XO's ears into AP mode. However, I do have USB wifi dongles that support AP mode and I just took a look into that on an XO 1.75 under 13.1.0. I had to install the firmware, but iw list reported that AP mode is supported. So if the idea is to have the XO be a self contained wifi AP, an external dongle might be a solution. This particular SMC Networks USB wifi dongle was on Woot a few years ago for like $5/each. I got two, because, well, that's a good price and these things come in handy. lsusb reports this: (after yum install usbutils) Bus 001 Device 006: ID 0cf3:1002 Atheros Communications, Inc. TP-Link TL-WN821N v2 802.11n [Atheros AR9170] I went and got the firmware from here: http://linuxwireless.org/en/users/Drivers/carl9170#Firmware-1 Do iw list and you're looking for AP in this section: Supported interface modes: * IBSS * managed * AP * AP/VLAN * monitor * P2P-client * P2P-GO The native XO's wifi looks like this: Supported interface modes: * IBSS * managed With a Ralink USB wifi dongle on my Mint desktop, it just worked to turn it into an access point. I mostly followed these instructions for the Pi: http://thebitbangtheory.blogspot.com/2012/12/turning-raspberry-pi-into-wireless.html So unless someone comes out and says, hey, the XO's wifi does support AP mode, it's gonna have to be an external dongle.

[Server-devel] A possible alternative to Pathagar: calibre2opds
I use Calibre for my ebook management on my regular desktop and a while ago I saw a Calibre OPDS project. Basically you run it against your Calibre database and it generates a browsable catalog of your ebook collection. Calibre is cross platform, as is calibre2opds. Unfortunately calibre2opds doesn't generate searchable catalogs, which is a huge issue with huge collections. To sum it up, I put my 600MB Calibre collection on a USB drive, ran calibre2opds against it, and generated a web browseable catalog. I installed apache on a 12.1.0 XO-1, then mounted that USB drive on /var/www/html/books. Booted up a stock 12.1.0 XO-1, downloaded a few epubs from Browse, and they straight up opened in Read. I tried downloading a book in rtf format, but that wanted to open in Write and then Write just hung. And no, the XO-1 doesn't know what to do with mobi files. If you have a well organized Calibre library and don't intend to add books all the time, this would be perfect for a schoolserver. It doesn't require anything extra. If a school was upfront with which ebooks they needed, someone could create that Calibre database and set up calibre2opds for it. Ship it, it's done. Lives in an apache dir, there's no messing with it. Poking through my new Bookserver, I realize that I have not curated things the way I should. It's messy. But it's just for my personal use. Teachers could give little writeups, make sure the cover art is there, and make sure all books are in multiple formats. Most of my books are only in mobi, since I do the vast majority of my reading on a Kindle 3. As far as the server XO-1, it just needed a web server. I could have used lighttpd, but went with apache because that's what the XSCE is going to use. Seriously, all I did on the XO-1 was yum install httpd, started the service, and mounted the USB drive on /var/www/html/books. If you've never used Calibre, it is a very, very nice piece of software. Like iTunes for ebooks. Cross platform, and converts seamlessly (except for PDFs. That's always been crappy). You can edit metadata, get bookcovers, and insert your own blurb for the book. There are also plugins so you can strip DRM. Not that I'm advocating this, but a teacher could be visiting in the States and use her sister's library card or Amazon account to download a lot of ebooks, then she could import those books into Calibre and take them home and serve them up to her students. But that's a moral and legal issue outside our scope. Just an option if Pathagar proves to be too problematic.

On Sun, Aug 21, 2011 at 10:18 PM, Richard A. Smith rich...@laptop.orgwrote: Interesting. If you did in fact reflow anything then it was probably due to the poor temp regulation of your toaster oven. The solder in the XO is lead free and melts a higher melting point than 385. I don't know the exact formulation that Quanta uses but most lead free formulations melt at 215C which is 419F. Thank you for being the first person to offer actual data on this. Since I baked it at 385, or thought I did, if in fact the melting point is 419, then I didn't reflow the solder at all. I need to get an independent oven thermometer to stick in there if this turns into an habitual endeavor. If you actually didn't reflow anything then the forces from the large thermal gradient may have been sufficient to push the cracks back together enough to work again. (Sort of the same thing that happens when you test by pressing on the chip hard to see if it boots) A production line oven uses a soldering profile. Pre-heat, then a brief spike over the melting point and then a cool down. If you do a search for lead free soldering profile you will see loads of information on various profiles. Picking something that closely matches one of those profiles will give you the greatest chance of success. Good to know. Since this isn't like tempering steel, if something goes wonky in the future, I can examine what production lines do and try to emulate that as best I can. The wikipedia entry on reflow ovens wasn't very detailed, but I didn't know what else to search for so I just hauled off and did the best I could. I got most of my info from a message board where folks put their HP laptop mobos in the oven. As James mentioned if you forget and bake the RTC battery then there is a very high probability it will explode. At my previous job we once used old computer motherboards with thermocouples attached to tune our profile and we forgot to take out the RTC battery. It exploded but thankfully it was while it was inside the oven and no one was injured. Oh, yeah, I made sure to remove the battery. And anything else that might explode, catch fire, melt, or otherwise make a wicked mess. A couple of hours ago, I baked the second XO 1.5 motherboard and yep, it booted after that. I took tons of pictures this time. I'll post a writeup with the pictures in the next few days. At this point I feel like Julia Child. If Julia Child put circuit boards in her oven.

XO 1.5 Solder Reflow in Toaster Oven
A while ago, both my XO 1.5 units from the contributor's program pooped out. Wouldn't boot at all. My friend kevix said he had a similar issue with his and that it was a solder issue. I was going to send them back to Holt, but then I read about solder reflow. So, I took the mobo out of one of the XO 1.5 units, broke it down to just the board and nothing else, then put it in the toaster. On a metal pan supported by four balls of tin foil: 385F for 8 mins. Put everything back together and, to my complete and utter astonishment, it booted. In fact, I'm typing this email on it now. My question is, has anyone else ever tried this and, if so, are there more optimal time/temperature parameters. I still have the other XO 1.5 unit to attend to and I'd like to hear some feedback before baking it.

[Server-devel] Uploading files to the XS via a simple PHP form
A long while ago, a teacher contacted me wondering how he could upload files
to the XS. He had a Mac, so I set him up with an XS login and a dir in
/var/www/html and he used CyberDuck to scp the files. But what if it had
been a teacher who only had access to one of the school's XP machines? The
IT policy is so strict you can't install anything. While a few teachers
might be OK with scping files from an XO, most might not.
Now, I know Moodle handles file uploads, but some folks don't use it. Or
they might prefer to upload certain things outside of Moodle where Apache
can serve it.
Aside from security concerns, and the vain hope that your users aren't
careless idiots, this is extremely easy to set up.
Obviously, take care if your XS faces the outside world. On my test XS, I
put upload.html in /var/www/html/clubhouse, which is password protected with
.htaccess. Seriously, this is all it takes to make the form:
form enctype=multipart/form-data action=../upload.php method=POST
Please choose a file: input name=uploaded type=file /br /
input type=submit value=Upload /
/form
In /var/www/html, I created upload.php which says where to upload the file
(the target).
?php
$target = deaddrop/;
$target = $target . basename( $_FILES['uploaded']['name']) ;
$ok=1;
{
if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target))
{
echo The file . basename( $_FILES['uploadedfile']['name']). has been
uploaded;
}
else
{
echo Sorry, there was a problem uploading your file.;
}
}
?
The last step was to create /var/www/html/deaddrop and set the permissions:
chown -R apache:apache deaddrop
So now all the user needs to do is go to
http://schoolserver/clubhouse/upload.html, enter the login credentials if
you've set that up, upload a file from their local drive, then go to
http://schoolserver/deaddrop to see it listed in the index.
Users can't delete files, of course. Root needs to log in to take care of
that. Which means if a careless idiot accidentally uploads, ahem, home
movies, that will be up there for all to see until someone with root access
can take care of it.
And there's nothing that would keep you from setting up a password protected
teachers lounge with individual upload.html files that point to individual
teacher's web directories.
As always, comments, suggestions, and criticism welcome.

[Server-devel] Question on number of iptables rules
My test XS at home has a FQDN and is open to the outside. Therefore this is probably a pretty rare issue in XS land, but I thought I'd ask. I noticed my ambient rx/tx traffic on eth0 had gone from really low (like 0.1 to 0.7 kB/s) to hovering between 5-20 kB/s. I went through httpd's access_log and error_log and blocked a bunch of IPs that looked kinda sketchy. Chinese and Russian search engine bots, script kiddies looking for phpmyadmin, that kinda stuff. Of course, I do have robots.txt disallowing all user agents, but we know that's not always respected. Then I thought, rather than play whack-a-mole with individual IPs, I'll just block China and Russia altogether. However, that brings up another question. Between China: http://www.wizcrafts.net/chinese-iptables-blocklist.html and Russia: http://www.wizcrafts.net/russian-iptables-blocklist.html that's a ton of IP addresses. Getting them into /etc/sysconfig/olpc-scripts/iptables-xs is easy enough. I pasted the IP data into a file named banned_ips.txt and ran this little script: #!/bin/bash for i in $( banned_ips.txt); do iptables -A INPUT -s $i -j DROP done I didn't mess with iptables-xs.in, as I figured I might need to update and/or straighten stuff out and a simple IP list is a lot easier to manipulate. Of course, restarting iptables reloads iptables-xs.in and the block list is gone from iptables-xs. No big deal, as the above script just takes a couple seconds to run and they're back in there. Here's my question - is the XS networking going to get wonky with 894 extra iptables rules? I know every incoming connection has to be checked against it, so what's the max count of rules that's a good idea? And is there a better way to handle this? Anna Schoolfield Birmingham P.S. After blocking all these IPs, my ambient traffic has gone back down to normal. ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

On Tue, Feb 1, 2011 at 8:46 PM, Tom Mitchell mi...@niftyegg.com wrote: It can help to block China and Russia but the way spam and denial of service botnets work that is more limited than you might wish. Well, I'm not currently running a mail server, so luckily I don't have to worry about that right now. The Chinese and Russian stuff was in my httpd logs. And quite a bit of it, which gave me concern enough to want to block those two countries. I read that a lot of other server admins take a similar approach. Two tools denyhosts and PortSentry come to mind. They will deal with many blunt script attacks that come from anyplace on the globe even Iceland ;-) I'm running ssh on a non standard port, and have never seen any attacks in /var/log/secure. Not sure how denyhosts is supposed to help me there. As far as port scanning, I try to keep available ports to a bare minimum. I did look into Fail2ban, but since my issue seemed to be mostly Apache related, and the individual IPs varied quite a bit among the Chinese and Russian ranges, I can have tons of unwanted traffic before that kicks in. With a system live on the internet it is often valuable to block everything first and then open exactly what you need for exactly those that need it. So when I get weird stuff on port 80, I'm supposed to block the entire internet from my web server except my friends and my Mom? If I ask my Mom her IP address, she's likely to give me her phone number. Or maybe run Apache on a random port? Hey, y'all, when you try to go to my schoolserver, just remember it's http://schoolserver.example.org:4329; Not likely. The number of rules by itself almost does not matter. Sometimes the order of rules matters more. In iptables, I've got a few lines of regular stuff and then 894 drop statements for the IP ranges that are likely going to be problematic. Not sure what kind of order almost 900 drop statements are supposed to be in. For example you can drop/block all connections to telnet and many other port services in a very early rule and never need to test your long list of IP address blocks. The XS 0.6 doesn't ship with telnet and no one uses that any more anyway. All I have open to the outside world are ports for Apache, Jabber, and ssh. And my ssh port is non-standard and doesn't show up on a casual nmap -sS anyway. Again, never any issues logged as far as script kiddies poking around at ssh. And I do keep tabs on who's registered to the Jabber server. If I run ejabberdctl stats registeredusers and there's a ridiculous number, I can take a look at the web admin interface to see specifics. And then there are folks on my Jabber server pretty much 24/7 and I have all the chat rooms logged. I posted here because I wanted to know if 894 rules in iptables-xs was going to be a problem on XS 0.6. And if there was a better way to handle the issue. Log files always need to be watched. I do agree with you there. I try to look in on my httpd logs every couple of days. And the XS 0.6 logwatch emails are quite informative. I installed alpine, so keeping up with them is fast and simple. Anna Schoolfield Birmingham ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

[Server-devel] Administrative login for political reasons
I think enough time has passed that I can write this up in case anyone else runs into this situation. Back when I was tussling with a school IT guy, he demanded administrative access to the XSs. Err, you do realize there is no GUI whatsoever and all you're going to see is a prompt, right? He was a Windows guy and didn't want to admit he had no clue what to do with a CLI only Linux system. And got offended when I asked if he had an ssh client. Well, Mr. Big Shot, here's your precious admin access. I created an admin user and set a password. adduser admin passwd admin I use passwords for ssh, but do run it on a nonstandard port, deterring the script kiddies. Having previously installed and set up ssmtp so the XSs could send me emails via gmail, I edited /home/admin/.bashrc echo 'Login Alert on' `hostname` `who -m` | mail -s Login Alert m...@gmail.com Being of a nosy disposition, particularly when it comes to what's going on with my systems, I set it up to quietly log everything he did with this line in /home/admin/.bash_profile script -q /var/log/sessions/login-`date +%m-%d-%Y-%Hh-%Mm-%Ss`-`whoami`.log exit Created and set permissions to a dir in /var/log that looks innocuous: mkdir /var/log/sessions chmod 777 /var/log/sessions And just in case he reads something on the internet, here's some sudo rope to hang himself with. I can install and customize an XS in under an hour, so whatever if he breaks it. I was actually really looking forward to pulling logs to prove he was out of his league. visudo and then add an entry for admin under root. ## Allow root to run any commands anywhere rootALL=(ALL) ALL admin ALL=(ALL)ALL The hilarious bit was he claimed he logged into all my XSs and said everything looked OK.

At least you'd have a quick way to see how many XOs are being brought to school and be able to track that over time.

[Server-devel] Notes on Flashing the NAND over the LAN
With the release of 10.1.3, I thought I'd revisit flashing an XO over the LAN. Here are my notes, if anyone's interested. First off, if your AP is really old and only does B, you might run into trouble. The layout in my house is the XS in the front room with eth1 connected to a router. The router goes to an AP sitting next to the XS and a wall jack to the sleeping porch (it's a 1913 bungalow) with another AP back there. I call it my winter lab because there's a heater. The front room with the XS has been getting down to 40F, which is a bit chilly. My two APs are different Linksys models. The older one, which I picked up from a thrift store for $5, only does B and usually works for most things. The newer one does B/G. I did have the older one in my winter lab but swapped it out for the newer one, as you'll see. I started off by using wget to download these two files in /var/www/html on the XS: http://build.laptop.org/10.1.3/xo-1/os860/os860.img http://build.laptop.org/10.1.3/xo-1/os860/os860.img.fs.zip I copied os860.img.fs.zip to fs.zip. Then I set both my APs to the SSID of OLPCOFW. Since it was getting kind of cold, I went to my winter lab with the B only AP (and the heater). Plugged in an XO-1, held down all four game keys, and powered on. It saw the AP, associated to OLPCOFW, got an IP from the XS, erased the nand, and then tried to flash it. When I say try, it got about 5 green blocks in before completely stalling. Figuring the old AP was the problem, I swapped it out for the newer B/G AP from the front room. That AP worked. Flashing the XO-1 over the LAN took about half an hour, but it completed, rebooted itself, and was good to go. For mass updates, this would probably be highly inefficient and you're better off with USB drives or an XO set up to NAND Blast. But it's a nice option to have for the occasional reflashing. I had other trouble with the B only AP, like when I put this in /etc/sysconfig/network-scripts/ifcfg-eth0 on an XO: DEVICE=eth0 ONBOOT=yes BOOTPROTO=dhcp TYPE=Wireless MODE=Managed ESSID=OLPCOFW Trying to associate with the B only AP in single user mode with ifup eth0 fails. It works with the B/G AP, though. So now that I've verified flashing the XO-1 over the LAN works with the B/G AP, I'm curious to see if the XO 1.5 can do that as well. Short answer - no, I couldn't get it to work. I used wget to download these two files into /var/www/html on the XS. http://build.laptop.org/10.1.3/xo-1.5/os860/os860-4g.zd http://build.laptop.org/10.1.3/xo-1.5/os860/os860-4g.zsp.fs.zip I deleted the XO-1 fs.zip file and copied os860-4g.zsp.fs.zip to fs.zip. Following the same procedure as the XO-1 LAN flashing, the XO 1.5 said it was looking for ssid:OLPC-NANDblaster. I renamed the AP to OLPC-NANDblaster and this is all I got: Trying disk:\fs.zip Trying ext:\fs.zip Trying NANDblaster Boot device: /dropin-fs:nb15_rx Arguments: ssid:OLPC-NANDblaster Scan for: OLPC-NANDblaster found Associate with: OLPC-NANDblaster Waiting for server And then it just sits there. Oh, well, it would have probably taken a couple of hours to flash over the LAN anyway. Tip: I like to include the IP addresses of my APs and the router in /etc/motd. Then I need only login to the XS to see where I put them so I know where to go for their web interfaces. cat /etc/motd The Router is on 172.18.126.2 The B/G AP is on 172.18.126.3 The Salvation Army AP is on 172.18.126.4 Anna Schoolfield Birmingham ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

[Server-devel] IP Address Pools for XOs, known clients, and unknown clients on XS 0.6
I like to leave the AP open on my test XS 0.6 at home, but ran into an issue
with that yesterday. I noticed the lights on my router blinking like crazy,
so I did a live tail on the squid access log to see what was going on.
tail -f /var/log/squid/access.log
And oh, my goodness. One of my neighbors was on there checking his
Facebook, setting up his fantasy basketball team, and, ahem, looking at
copious amounts of adult material. First I checked to see if I knew who it
was via the Facebook user id I found in the squid log. No, I had never met
him, but Mr. Frank redacted strikes quite the caricature of a aging
redneck fratboy. In typical passive aggressive Southern lady style, I'm
going to teach him a lesson.
I don't want to put encryption on the AP or fool around with content
filtering, so I'm going to use some dhcp tweaks and iptables to put up an
obstacle to web browsing by unknown clients.
Edits for /etc/sysconfig/olpc-scripts/dhcpd.conf.1
Under the subnet declaration, I added a class definition for the XOs. This
works for the two XO 1.5 units I've got as well, but I'd verify the MAC on
any of those just to be sure.
subnet 172.18.96.0 netmask 255.255.224.0 {
class xo {
match if substring (hardware,1,3) = 00:17:c4;
}
Since I'm going to separate things into pools by range, I comment out this
line:
#range 172.18.96.2 172.18.125.254;
Beneath the lease times, I add my pools. Adjust your ranges as needed.
# Address pool for just XOs
pool {
allow members of xo;
range 172.18.96.2 172.18.123.254;
}
# Address Pool for unknown clients
pool {
range 172.18.124.2 172.18.124.254;
deny members of xo;
deny known-clients;
allow unknown-clients;
}
# Address pool for known clients
pool {
range 172.18.125.2 172.18.125.254;
deny members of xo;
deny unknown-clients;
}
Make sure all that is within the ending bracket of the subnet.
At the very bottom of the file, below everything else, I add the known
clients.
# Non-XO stuff on dynamic range 172.18.125.0/24
host anna-eeepc-1 {hardware ethernet 00:15:af:ec:9e:46;}
host anna-eeepc-2 {hardware ethernet 00:22:43:2e:fe:79;}
host tyler-eeepc {hardware ethernet 00:15:af:ec:96:1f;}
And because I'm ticked off, and inspired by
http://www.ex-parrot.com/pete/upside-down-ternet.html, it's time for some
fun with iptables. In /etc/sysconfig/olpc-scripts/iptables-xs.in I add a
couple of lines like so:
*nat
:PREROUTING ACCEPT [0:0]
:POSTROUTING ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A PREROUTING -s 172.18.124.0/24 -p tcp --dport 80 -j DNAT --to
205.196.209.62
@@SQUID@@
-A POSTROUTING -o @@WAN@@ -j MASQUERADE
COMMIT
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A FORWARD -s 172.18.124.0/24 -p tcp --dport 443 -j DROP
COMMIT
Restart dhcpd and iptables:
service dhcpd restart
service iptables restart
Now all unknown clients will have http traffic redirected to
http://kittenwar.com and their https traffic is dropped.
Obviously this isn't a deterrent to someone who can use an ssh proxy for
browsing, and it doesn't block traffic on other ports or protocols, but most
of my neighbors aren't of the networking savvy sort (particularly the
grotesque rednecks) and will likely conclude this darn internet ain't
workin' no more. If I lived near MIT, this would not be an acceptable
solution. But I'm not terribly concerned many folks around here know much
about packet sniffing or MAC spoofing.
When guests come over and want to look at something other than pictures of
kittens, all I have to do is add the MAC to the list of known clients,
restart dhcpd, and tell them to renew their IP.
At the very least, now I know how to keep XOs and non-XO clients on
different IP ranges.

I have read what is on the wiki, but I must be missing something. Can someone provide some detailed instructions? Thanks. Gerald Gerald: Though you're supposed to use keys, and I still do from my main desktop, it's convenient when you're sshing from multiple XOs or other computers to go ahead and enable password based ssh login. That way you don't have to fool with keys all the time. Since my XSs are exposed to the internet, I do run ssh on a non-standard port, which keeps out the script kiddies. If you're worried about that, it's really simple to change the port. Anyway, it's just a config file edit to allow password based ssh logins. As root, create a regular user on the XS. adduser gerald passwd gerald You'll be prompted for the new password. That's it for setting up a user. Enable password authentication in /etc/ssh/sshd_config and /etc/ssh/ sshd_config.in I think you're supposed to be able to edit only sshd_config and then run make -f /etc/xs-config.make sshd_config to do up sshd_config.in properly, but I just go ahead and make this minor change to both files, as I've never gotten xs-config.make to work consistently for me. In both those files, uncomment PasswordAuthentication yes and comment out PasswordAuthentication no so it looks like this: # To disable tunneled clear text passwords, change to no here! PasswordAuthentication yes #PermitEmptyPasswords no #PasswordAuthentication no Restart the ssh service. service sshd restart Now from an XO connected to the XS, you can ssh ger...@172.18.0.1 or ssh gerald@XS's hostname Enter in your password and you should be greeted with the motd! After you successfully ssh in, you can su root. Sometimes that's not root enough, though and you might have to 'sudo su -' if it says you can't do something.

I was testing the server with about 12 XOs today. They all connected fine and had internet connections. But the performance seemed slow. It took several seconds for pages to load at times. Also, when I tried to have shared Activities (I opened a chat session, for example), the performance was horribly slow, and not every computer could connect. Do you have any ideas about why this might be happening and how to make it better? Thanks. Gerald The slow page load in either Firefox or Browse is usually helped quite a bit by disabling ipv6. In a (recent) Browse activity or Firefox, enter about:config in the address bar. Type ipv6 in the filter bar. The Preference Name you're looking for is network.dns.disableIPv6. Double click it to set the value to true. That usually helps page load speed quite a bit. If activities seems really slow when they're shared over the XS versus the XO-1 mesh, I don't know what that might be other than the throughput of your AP. If you suspect your XS setup, you can always connect to my test XS 0.6 running a semi-public Jabber to see if there's a difference.

Restart the ejabberd service.
I don't need to create the admin login on the XSXO as I've already done that
on the XS with these two commands:
ejabberdctl register admin schoolserver.example.org password
ejabberdctl set-password admin schoolserver.example.org password
Migrate the ejabberd database from the XS to the XSXO. This takes care of
the admin login as well as any persistent chat rooms you've already set up.
It should go without saying that you need to keep this up to date. You can
restore the ejabberd backup on the XSXO as many times as you want and it'll
just overwrite the old database.
On the XS, create the backup file:
ejabberdctl backup /tmp/jabber.bak
Copy the backup file over to /tmp on the XSXO. Change permissions:
chown ejabberd:ejabberd /tmp/jabber.bak
Restore the backup to the XSXO:
ejabberdctl restore /tmp/jabber.bak
Check to make sure it took. Run this on both the XS and XSXO and the counts

I got the XSXO to boot in about 53 seconds. When you're scrambling around

If you're not using these services, turn them off with chkconfig --level 345
service off
hddtemp

xs-rysncd
Use chkconfig --list to see which services are set to run on which runlevel.
To further speed up boot, go into /etc/sysconfig/network-scripts and move
the devices you're not going to use into a backup directory. You can always
put them back later.
cd /etc/sysconfig/network-scripts
mkdir bak
mv ifcfg-eth1 bak
mv ifcfg-lanbond* bak
mv ifcfg-msh* bak

Turning off the backlight will reduce power consumption a bit, especially
important if you've only got a car battery to charge it with.

echo 0 /sys/class/backlight/dcon-bl/brightness
Turn the backlight back on:
echo 15 /sys/class/backlight/dcon-bl/brightness

* Switching over *

So the power just went out. I hook the inverter up to a car battery and
plug my DSL modem into it. While the connection comes back up, I safely
shut down the regular XS and turn off the UPS to stop that infernal
beeping. Power on the XSXO and get an IP from the router. Log into the
router's web interface and put the XSXO into the DMZ. Renew the IP on the
XSXO.

Can the BIOS see the hard drives? If you don't know if the machine itself is working outside the hard drives, have you tried booting from a Linux rescue CD? Some folks like Knoppix for that. I tend to use Ubuntu NBR (cause I usually have that CD on top of the stack). But there are a myriad of Linux live CDs out there. If you can get into a live Linux boot, ls /dev and see if you see your hard drives. If you don't see them, or can't boot into Linux from a CD, then it's time to break the box down and reconnect the drives. Or check the power supply. I've run into so many hardware issues with the old stuff I work with, I can't even keep track of how many problems I've had. Hard drives give me special trouble. If I can actually see the stubborn drives in /dev, I'll use gparted or fdisk to format to a single fat32 partition. Then the XS install usually picks it up.

Re: [Server-devel] Jabber presence under NAT named under DMZ issues
Thanks to Jerry's and Martin's notes, I got the XSXO working correctly in my router's DMZ with my external IP and FQDN. I also hotswapped the XS, so to speak. XSXO1 = the install where named broke XSXO2 = my second install XSXO2: After first boot, I edited /var/named-xs/school.external.zone.db for my external IP. Then ran domain_config and named started up without error. That was it. Rebooted. On XSXO1, I backed up the ejabberd db: ejabberdctl backup /tmp/jabber.bak Copied it over to /tmp on XSXO2 and restored it: chown ejabberd:ejabberd /tmp/jabber.bak ejabberdctl restore /tmp/jabber.bak XSXO1 had live Jabber chat users (and has had for the past few days). I gave folks warning, then physically unplugged the USB ethernet adapter from XSXO1 and hooked it up to XSXO2. It came up as eth0 and then everyone automagically came back online! My router sees the USB ethernet adapter's MAC as the DMZ device, so I figured it would do that. I know the XO-1 is a tiny, tiny server but my Jabber user group typically has no more than a dozen users online at any given time. I was just hoping XS on the XO-1 would prove to be a viable backup solution to my big old Dell XS in the event of system maintenance or a power outage. As far as the Jabber presence resetting itself every hour when the XS is behind NAT, I suspect it might be my router. The ejabberd logs only indicated that users disconnected and then reconnected. Robert Howard, one of my Jabber users in San Francisco, is sending me one of his spare DSL modem/router units to try out. Also, given my previous unsuccessful attempts at XS 0.6 on my big old Dell (currently running XS 0.5.2), I'm glad to finally know how to get networking up without breaking named. And now I have a backup XS to keep everyone happy while I update from XS 0.5.2 to 0.6. (My users are borderline obsessive.) The XS's I've set up at schools currently don't have this issue with XS 0.6 as they're not public facing, but their DSL connections do have external static IPs.

The XSXO has an IP from my LAN (192.168.1.200 for example) and I can forward 80, 5222, 5223 (or other ports!) to it and the presence service doesn't reset every hour. 2.

Re: [Server-devel] Bridging XS to another network
David: I'm a little confused as to your setup. If you just have the one ethernet device on the XS, it can either get an IP address from your router (as eth0) or hand out DHCP addresses (as eth1). It can't be in both roles. I've played around with external access for the XS and it does involve some firewall stuff. I think I used lokkit to configure access to port 80 and the jabber port to my regular LAN. Then I opened up those ports on my router firewall for access from the rest of the internet. By way of example, here's a setup I've done in the past: Regular LAN: XS (eth0) 192.168.1.20 My Desktop 192.168.1.6 XO A 192.168.1.7 XS LAN: XS (eth1) 172.18.0.1 XO B 172.18.96.2 On the XS LAN, XO B can go to http://schoolserver or 172.18.0.1 and see the default Moodle homepage. It can also register to the XS and all that good stuff, cause it's getting its IP address from the XS's DHCP server. On the Regular LAN, my desktop and XO A can't see the Moodle homepage at 192.168.1.20 until I open port 80 in the firewall on the XS using lokkit (or edit iptables or whatever). Since XO A is not getting its IP address from the XS, it won't be able to register. If XO A wants to use the XS's Jabber server, that port needs to be opened in the XS firewall. XO A can now manually set the Jabber server to 192.168.1.20 and collaborate. If you want to use Moodle, not being able to register to the XS is a huge issue. Apache access works fine, though. I use ifcfg-eth0-local to set the static IP for eth0 on the XS. Here's my example: IPADDR=192.168.1.20 NETMASK=255.255.255.0 NETWORK=192.168.1.0 BROADCAST=192.168.1.255 GATEWAY=192.168.1.254 To see what I need to put in there, I'll do this on another Linux box connected to my Regular LAN: a...@anna-desktop:~$ ifconfig eth0 eth0 Link encap:Ethernet HWaddr 00:0f:1f:80:0d:ea inet addr:192.168.1.4 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::20f:1fff:fe80:dea/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1328780 errors:0 dropped:0 overruns:0 frame:0 TX packets:1018129 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:1602636271 (1.6 GB) TX bytes:98891469 (98.8 MB) a...@anna-desktop:~$ netstat -nr Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 0.0.0.0 192.168.1.254 0.0.0.0 UG0 0 0 eth0 If you're trying to have all the services available with just the single ethernet port, good luck.

Re: [Server-devel] How to configure XS with only one Ethernet port
If I'm messing around with different ethernet devices (a USB wifi adapter or USB ethernet adapter) and stuff isn't showing up the way I want, I'll take a look at /etc/udev/rules.d/70-persistent-net.rules For example, if I want to get my internet connection from my USB wifi adapter, which shows up as wlan0, I'll go in there and edit wlan0 to eth0, making sure that's the only eth0 in there. Or sometimes if I've been plugging different USB things in and out and I want to start over, I'll remove all my USB doodads, delete that file, reboot, and start afresh. I'll also take a look at that file if I'm moving around physical cards to make sure that what I want to be eth1 is showing up as that and not eth2. My older/cheap hardware can be persnickety.

Re: [Server-devel] automount external HD
If you've got an /etc/fstab entry for the drive, you could tell udev to mount it. I think this'll require the auto option in fstab.

Last, the domain_config thing. Then reboot.

[Server-devel] Upgrading BIOS on an old Dell without Windows or Floppies
I know this has nothing specific to do with the XS, but maybe it'll help others, as I spent ages searching around for the solution. Some of us are reusing legacy Dells and those can be difficult to deal with in a Linux only environment. So just in case other folks are re-purposing old Dell machines as XS's and are in a similar situation in regards to wanting to upgrade the BIOS - you'll need: a Linux box, CD Burner, and 2 CDRs. We have a bunch of old Dell Optiplex GX270 boxes to use as XS's. I want to update the BIOS from A04 to the newest A07, but don't have access to a Windows machine nor possess any floppies. I certainly wasn't about to go and buy floppies just for this, let alone install Windows. And I've never been able to successfully boot a USB drive on these boxes, so that's out. Luckily an OpenSUSE user had the exact same quandary and posted the solution: http://collinpark.blogspot.com/2009/06/more-pain-opensuse-111-on-my-dell.html I downloaded the LiveCD version of FreeDOS 1.0 and burned the iso to a CD. It's 153M. http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/1.0/fdfullcd.iso Then I got the BIOS update from Dell. Of course it's an exe file which doesn't let me do anything with under Linux. I tried to extract it, but just produced a bunch of errors. Forget that, then. I burned the BIOS file GX270A07.EXE to a data CD, which seems kinda a waste of a CD for such a small file (540K). But I've got scads of CDRs and no desire to trot over to Office Depot just for floppies. Besides, I've got a lot of these boxes to update, and I suppose it doesn't feel like such a waste when I think of how many times it'll be used. I boot the FreeDOS CD and hit enter at the prompt. Then hit 5 for the FreeDOS Live CD Only option and after a few seconds, got an A:\ prompt. I eject the FreeDOS CD and insert the CD with GX270A07.EXE. **This is important: wait for the CD-ROM drive LED to quit blinking before you do anything.** If you try to access the drive too soon, you'll get an error and have to reboot. I enter DIR X:\ and see the exe file. Then I simply enter: X:\GX270A07.EXE I'm prompted twice to hit y, then cross my fingers and hope the power doesn't go out for a few seconds while it flashes. Yeah, a UPS is probably a really good idea. It automatically reboots and I hit F2 to get into the BIOS setup. Wow, there's A07! If you happen to be using a similar machine, might I recommend Power Management - AC Power Recovery - Last. That way if the power goes out and the UPS dies (if you're lucky enough to have one), the XS will automagically power back on when power is restored. Here's the the obligatory: YMMV, the process will likely be different with other models, and be careful otherwise you might brick the mobo.

Re: [Server-devel] Postfix vs ssmtp conflict on XS 0.6
Thanks, Martin! I was hoping it would be OK. Sometimes I never know what's going to break when I start messing with things. I uninstalled postfix, installed and configured ssmtp for gmail, edited the mail group for root (requires reboot), installed mutt with no further configuration (the simple mail command doesn't handle attachments), and downloaded and installed the sarg rpm (it's not in the repos). This hacky, crappy, inelegant script sends the recipient a simple email with the daily squid access report. I tested it in crontab just to make sure. The files are in zip archive for the Windows folks. They do have to unzip it and manage to open the index.html file. But if folks want to see where the kids are going on the internetz, this seems like an easy way to provide that data right in their inboxes. #!/bin/bash recipient=exam...@example.com today='date +%0e-%m-%Y'; mkdir /root/squid sarg -l /var/log/squid/access.log -o /root/squid -z -d $today zip -r internetlog.zip squid/ echo This is the Internet activity log for $HOSTNAME |mutt -a internetlog.zip -s $HOSTNAME Internet Log $recipient #Cleanup rm -rf /root/squid exit Since I know this is a crappy script, you won't hurt my feelings if you point out how awful it is.

[Server-devel] (Mostly) Enforcing Google Image Safe Search With Squid
I just installed the latest XS 0.6d2, and in addition to setting up OpenDNS in named-xs.conf to do the usual filtering, hunted around to find an easy way to enforce safe Google image searches, as that seems to be an issue. Looks like squid can block urls via regular expressions. I created a file named /etc/squid/blacklisted_sites.txt consisting of: http://images.google.com/preferences http://images.google.com/advanced_image_search safe=off and added the following lines to /etc/squid/squid-xs.conf.in at the beginning of their respective sections. acl blacklist_sites url_regex /etc/squid/blacklisted_sites.txt http_access deny blacklist_sites Then, of course, make -f /etc/xs-config.make squid-xs.conf And then /etc/sysconfig/olpc-scripts/TURN_SQUID_ON So now when I attempt to turn off safe search, squid gives me access denied. A *horrible* issue was when I tested what would happen if I came to school with safe search already off in my cookie. Well, it doesn't block the first results page as Google doesn't put safe=off in the url string, but it does block the next page. Small comfort if you're the teacher with that kid in your class, though. Oh, only one page of nasty thumbnails. That's not disruptive at all. It blocks the preferences page link from the image results as well, so you're stuck with whatever you connected to the XS with, even if that happens to allow the depraved corners of the internet. We can't help what kids do at home, though. I don't know if safe=off is the best thing to block on, as there might be some legitimate sites with that string in the URL, but somehow I doubt it. The non XS specific part of the instructions came from http://learnlinux.tsf.org.za/courses/build/electives/ch03s03.html I sure hope someone out there has a better idea.

2008/12/31 David Leeming leem...@pipolfastaem.gov.sb I want to do a new install but can you let me know if I can install Samba and how to set up access to a shared folder on a Windows PC on the LAN as I have a large content collection and it takes ages to copy it all again by flash drive. Or maybe there is a better way to do it. I was curious about that, too, so I looked into other alternatives as Samba can sometimes be a pain to configure. It's also yet another service to run on the XS. I found an sshfs utility for Windows called Dokan. And it's free for non-commercial purposes! This might make more sense than fooling with Samba, especially if you only have one Windows machine to deal with. The Dokan library and Doken SSHFS packages are at http://dokan-dev.net/en/download/. I also had to install the Microsoft Visual C++ package mentioned on that site, the .NET Framework (which was 55 MB), and Windows Installer 3.1.
