[Server-devel] XS server struggles
G'Day all, I am trying to setup up an XS server to support a deployment we have of XO 1.5's in Timor Leste. I have setup a USB boot and have worked through David Leeming's XS installation instructions and I appear to have a working XS server, I can ping and access the yum repos via eth0 (I used xsau-testing for my update). I am not using a wireless access point, I was figuring I could just use the wireless of the small netbook to communicate with the XOs (although I note that the wireless port of the XS server has no IP allocated). Is this a bad assumption ? - is there something I should be reading about how get the XOs using the XS - I want to be able to use the XS mainly for software distribution, so as to avoid the folks in Timor having to insert a flash drive into each XO ..is this possible if so how and what do I read to find out how to do this ? thanks for any pointers/help regards Tom Daly ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

[Server-devel] Accessing a XS server from the WAN
Hi, OLPC France has managed to install 2 XS Servers. The first machine will be shipped to our deployment in Nosy Komba (Madagascar). As for the second machine, it should be used for testing and training purposes. How do we manage to access to this server from the outside? This training server is installed on a netbook (acer aspire one) with one physical ethernet interface (eth0). A second wired link is provided by an usb-to-lan adapter (interface lanbond0). Actually, the moodle server is accessed from another PC (non XO) via this lanbond0 interface. As I am not a network expert, I didn't manage to access from the public interface (provided by the eth0 interface) from inside the LAN. Another issue is that the server keep invisible to an XO (even if IP addresses are assigned to the wireless interfaces mshbond0, mshbond1 and mshbond2, with 172.18.10.1, 172.18.12.1 and 172.18.14.1).

You can change the configuration of ssh to listen on the eth0 (WAN) address. Create a non-root user account, and setup pubkey authentication. Use that account to login, and then su to root. If the IP address is dynamic, you can use a service like dyndns. Install the appropriate script to run on cron or on ifup-post (dyndns website has the documentation...) This assumes your XS has a public IP address, and there are no firewalls preventing access to port 22. IME, it is very likely that your XS hasn't got a public IP address -- instead your ISP will have it behind a NAT box. In the case where the XS is behind a NAT box, you'll need to ssh out from the XS to an intermediary server, having that outbound ssh connection configured to setup a reverse ssh tunnel. The xs-callhome script (included in the XS install) is a good example, but is currently broken. As I am not a network expert You might need a network expert then :-( right now this is not easy to do. It's on my to-do list to make this easier, but that list is long long long... Another issue is that the server keep invisible to an XO Explain that problem in more detail. From any XO, once you are associated to the right AP, you must be able to `ping schoolserver`. (even if IP addresses are assigned to the wireless interfaces mshbond0, mshbond1 and mshbond2, with 172.18.10.1, 172.18.12.1 and 172.18.14.1). DO NOT DO THAT. Do not change _any_ network settings on the XS, except for the eth0 configuration toget connected to the Internet.

Re: [Server-devel] Web Caching for Areas with Intermittent Internet - WWWOFFLE installation Guide on 0.6 XS Server
Hi Andra
Fantastic! Thanks! Couple questions:
- Can we remove the need to set proxy on every XO by either...
- using a transparent proxy, same as we do with SQUID (maybe make a
TURN_ON_WWWOFFLE script)?
- serving a proxy autoconfig file via dhcp/apache?
- Is it viable to automate the go online / go offline with a
cronjob that pings a public host ( ping -c1 google) every 5 minutes?
Or...
- If there's a daemon managing the connetion (case of pppd), use the
down and up hooks? This would only work if the daemon catches the
link is lost situation reliably.
- Made a rough copy/paste to

Squid apparently is not well suited to serve up cached pages when no
internet access is
available. It was recommended that I use WWWOFFLE for this situation. Here
is the
process I used to get it installed and running on my 0.6 XS server:
- Make sure that squid is turned off
/etc/sysconfig/olpc-scripts/TURN_SQUID_OFF
service iptables restart
- Create a directory for downloads (optional) and download and install the
wwwoffle file
mkdir /downloads
cd /downloads
wget http://dl.atrpms.net/all/wwwoffle-2.8b-2.0.1.el5.i386.rpm
yum --nogpgcheck localinstall /downloads/wwwoffle-2.8b-2.0.1.el5.i386.rpm
- When the installation finishes you need edit the wwwoffle.conf file to
configure it for the XS
ed /etc/wwwoffle.conf
- Change the line http-port = 8080 to http-port = 3128 using
the
search / and change c commands as follows:
/http-port / (search till you get to the line http-port = 8080)
c
http-port = 3128
^c (control-c stops the changing)
- In a similar manner search for and change the following in the LocalHost
section:
localhost to YourDomain.org (In my case this is asilong.org)
- Add a line in the LocalNet section to get:
LocalNet
{
*.YourDomain.org (In my case this is *.asilong.org)
- Add a line in the AllowConnectedHosts section to get:
AllowedConnectedHosts
{
172.18.96.* (Add any other AP IP groups as needed)
- Write the changes w to save them and quit the editor q
w
q
- Start the wwwoffle daemon
wwwoffled -c /etc/wwwoffle.conf
wwwoffle -online (For when your internet connection is online)
wwwoffle -offline (For when your internet connection is offline)
- Turn your XO proxy settings on using Browse and going to the URL
about:config
- filter the word proxy and double-click to adjust the settings to:
network.proxy.http (172.18.0.1)
network.proxy.http_port (3128)
network.proxy.type (1)
Teachers can now download pages of interest and then students can access
them
quickly, even if the server has no internet connection simply by putting
wwwoffle -offline.
Give this a try if your internet service is intermittent, or you are paying
by the GB for
your data download.

[Server-devel] Configuring XS Server to work in an existing network
Hi from the Red Centre I work for the Northern Territory Education Department in Alice Springs, Central Australia. We have been trialling the XO laptops with our primary schools in an existing network infrastructure, where the main school server (Windows) supplies the dhcp, file sharing, printing and web proxy services. The XS server works fine in a scenario where there is only one classroom and the wireless access points are connected to the eth1 interface of the XS server. The problem arises when there are multiple classrooms connected by optical fibre and there is the requirement to use only one XS server for the school. What I would like to be able to do is register an XO to an XS server, via an access point connected to the school network. The XO receiving its ip address from the Windows server and registering with the XS server which has a fixed ip address. I realise that this is a deviation from the OLPC server development path, but hope that someone may have already been down this path. Any assistance with a solution to this challenge will be greatly appreciated.

You may want to focus on channels 6 and 11, because out of the box XOs which have not yet connected to an access point will start meshing on channel 1, this may saturate the spectrum with a sufficient number of laptops. I do not think you need rounds of registration. With sufficient access points, you should be able to get 450 users online concurrently.

Re: [Server-devel] XS server
2008/10/23 Henry Vélez Molina [EMAIL PROTECTED]: Verifying from the Terminal activity, we note that doing the ping schoolserver , he print ous: uknown host. We believe that the problem is the Access Point. I agree! That sounds like the AP is acting like a gateway (and that's not what you want). Configure it to be a plain AP - it should set to _no_ routing, no NAT, no DHCP, no DNS. As for the Activity Server and Server Activation Is it possible to deploy at the moment? If you cna wait a few days for the final release of 0.5, then yes. cheers, m -- [EMAIL PROTECTED] [EMAIL PROTECTED] -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff ___ Server-devel mailing list [EMAIL PROTECTED] http://lists.laptop.org/listinfo/server-devel

XS server
Hello everybody. We have been doing tests with the XS-server, to know if it is properly configured. We have some difficulties and some doubts. From any PC or XO can access the administration panel ejbabberd, but if you try to make the automatic registered since the XO, tells us that he has not found the server. Verifying from the Terminal activity, we note that doing the ping schoolserver , he print ous: uknown host. We believe that the problem is the Access Point. But oddly enough, through the Web we can access the administration panel of ejabberd's XS and that the XO can not access it automatically. Running ifconfig (XO) and ipconfig (Windows) received notice that the ip is the administrative panel of the Access Point and not the Server. Perhaps this is the reason why the XO is not registered automatically. When connected through the LAN XS with a standard PC, ipconfig prints the ip of the server and the DNS correct. If we use a client jabberd, you can create accounts and use the services of the server automatically. Our AP is: *Model 4401 AP+4 Wireless-G Access Point/Router/4-port Switch/Repeater/Ethernet-to-Wireless Bridgehttp://www.zoom.com/graphics/datasheets/networking/0998_4401_AP4.pdf *** = http://www.zoom.com/products/glan_overview.html We would like to know that comercial Access Point , has been tested with the XS and you known they work. Do we need something else to set? As for the Activity Server and Server Activation Is it possible to deploy at the moment? thank you for your help.

Upgrading XO from a XS server
I see there is a page (http://wiki.laptop.org/go/Upgrade_Server) describing a way to make an upgrade server. But it uses a debian system not an XS server. And the software is not _released_ yet. Is it safe enough to use in actual deployment? Check me if I'm wrong but it looks like there are really two _official/supported_ ways to upgrade: via internet or via a usb drive. -- Philippe -- The trouble with common sense is that it is so uncommon.

Yes; the software has been (relatively) happily deployed on update.laptop.org for a year. I don't know how easy it is to install, but once installed, it seems to run fairly smoothly. The other thing you might want to be aware of is 'xs-rsync'. Ask Martin on server-devel@ for more details. Michael ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Shorewall works independently from iptables allowing its rules to work along side it... All the config files are in /etc/shorewall, which Im sure xs-config wont touch... xs-config is loading its own fw configuration, which will evolve to include quite a few rules that overlap with the shorewall rules. I'm not sure which one gets loaded first. It will be a matter of time until it blows up. To keep this converstation constructive I need you to think deeply about these things long term. For example, in the face of my earlier email, some of the questions facing you are: - what will happen when the stock config of the xs brings in a set of iptables rules that define conflicting rules for the same packet? - what if we get custom chains conflicting names? what if the default policies don't match? - do we even know which one gets loaded first? reloaded? torn down? I can add subtler ones like: will shorewall adapt to adding/removing interfaces the same way as the network_config scripts do?. For instance, these modules will not affect xs-config as far as I can tell: Odd interactions with local configurations I am recommending you don't do are... well... not supported. I can - and will - help you lots as long as you are heading in a direction that makes sense with where the XS is going. For bespoke configurations, well, I can only say: minimise them or fear the upgrade. So given that you cannot predict what configs will interact badly with future updates and what configs will just be overwritten, my recommendations are - change the least possible - keep the config files you change under version control - plan each upgrade carefully - test it first on a complete clone of the XS (a hd clone, with all the real data) to see what breaks, and be prepared to apply the fixes Every service you get ahead of time from the main XS development track is something you will need to understand *in depth* to be able to get in sync with when the XS implements it. For example, you are talking about a custom config of moodle - fantastic. However when the XS does include moodle, it will probably overwrite your Moodle installation -- hint: don't put it in var/www/moodle, don't call the database moodle or xsmoodle :-) -- and have things configured *very* differently. It will be significant work to understand and migrate your data from your early moodle to the xs moodle - work I cannot help you with. On the other hand, you could decide that you'll reinstall everything once the XS images are more featureful. In that case, *go wild* :-) cheers, m -- [EMAIL PROTECTED] [EMAIL PROTECTED] -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

Reread my notes above - an XS update will probably kill it, and you won't be around to help fix it. It's not that SW is not good - I've used it myself quite happily - but that it is not a sustainable move. Would u care to elaborate on how to do this I've outlined two options. Pick one, yum install the packages and read the man pages :-) Also note that openldap is very brittle when it comes to unexpeted poweroffs and stuff like that. It gets its BDB DB in a tangle even when running normally - a simple ldapsearch pattern | sed | ldapmodify script can corrupt the DB. Bad juju with openldap. Very bad. 5. Install Webmin for overall (internal) gui manipulation of the server... Ugh! Not recommended and xs-config in its current incarnation is lilkely to just make a mess of it all. I am not too proud of xs-config, and Webmin is too horrible for words. Its a matter of opinion... It is a lot more serious than that David. I can almost guarantee xs-config and webmin will interact disastrously. Not just webmin (though I worked with its internal code circa 1999 and... ), but anything that wants to change the config files. Any changes to config files that xs-config controls will bring grief, my worry with Webmin is that it makes it easy to change a lot of stuff that xs-config will later re-change. And I am sure modern Webmin will try and be smart about it - with a good chance of making things worse. Unless it has developed mind-reading abilities, the result will be ka-boom. It's not just Webmin: any administration program, web-based or not - is *not* recommended on a XS. And by that I mean the next yum update very likely leave the machine in non-working state. xs-config is a bit nasty ATM, but even if we make it better, it wil _never_ interact well with a webmin-type app. Sorry. Life is hard like that. need... I have no idea what xs-config is... but I'll gladly take a look... It is what configured everything in the XS. Dragons. There. Yes, right there. Nah, I'm not kidding. 6. Install various server monitoring tools Install whatever tickles your fancy but do install sysstat and make sure it's logging. If you need help, or can provide load stats, it will be the sysstat logs that we'll want to look at. yeah, I think we've settled for Nagios... seems to be allround for what we need... Ill make sure to sysstat and post the logs... Yup, nagios is ok. Cacti too. And BB if you want.
