 Tony, thanks for the suggestions and feedback.  This is what I wound up 
 selecting based on Rueben's input:
 
 http://www.logicsupply.com/products/ag150
 
 Spec'd with 2GB ram and 500gb drive with expedited test+build and shipping so 
 it would arrive to me before I leave for Uganda it was $597.  Not awesome but 
 time was of the essence.
 
 One question - the AG150 has a single Ethernet port as well; why do you need 
 an extra adapter?

Get a USB ethernet adapter.

  Does the XS play the role of NAT/router to the Internet as well?

Yup :-)

http://wiki.laptop.org/go/XS_Installing_Software#Network_configuration

 
 I did not spec wireless in the device but there is still time to add one 
 (Intel 1030, 6205 or 6230 PCIe cards).  Should I?

No - Get the USB ethernet adapter.

 Hi all,
 
 I'm leaving for Uganda next Monday and will be volunteering for a couple of 
 days at Kasiisi.  Apparently nobody knows the password to their server and it 
 has stopped functioning as they expect it to.  They have about 200 laptops.
 
 They would like me to bring a new server with me which I am happy to do (or 
 tell them what to order) but I don't feel comfortable sizing or specing it.  
 I'm also not sure where to acquire it.  I'm hoping someone can provide some 
 direction on short notice?  It would especially great if I could acquire the 
 hardware and get XS installed before I leave but time is short.
 
 Anyone available for a consult on this?  I'm located in the SF Bay Area if it 
 makes a difference.
 
 Thanks!
 
 
 Brian

I believe they have 200-300 XOs which any standard spec'd server should handle.

 Edward, Elias,
  
 Let's look at this in phases:
  
 -1: The XO has no lease and needs a lease to run. So using either method (a. 
 Standard Leases) or (b. Delegated Leases) you  preload the XS with leases.
 -2: You turn the XO and it the SD card, USB, and Open Wifi for a lease.
 -3. It finds an open AP connected to the XS which contains a valid lease and 
 is transferred to the XO over the wireless.
 -4. Now the XO can run until the lease runs out. During this time two things 
 can happen. The lease can be auto-updated through method (b) or the lease can 
 expire and the XO will have to request a new lease from the server again in 
 the same fashion as #3. 
 -5. Now if you follow method (b) you will be able to mark the laptop stolen. 
 The problem you are seeing is that you have not implemented method (b); 
 therefore the XO does not trust the stolen message that it received from 
 the server.

 Yep.
 But as explained before, the dhcp server was sending the ip address,
 we only get an issue with the DNS (not set on the client
 automatically).
 Moreover, the options should be defined in the subnet, not global as
 done in the original file.
 Still no luck.

Interesting. We've heard and I've seen no other issues previously with this 
configuration.

 Hopefully it's only matter of one file and 5 or 6 lines with dnsmasq.

Glad you got it sorted.

 We are currently configuring the XS server for the deployment in

 Could you resume the main part of the DNS/DHCP config on the XS (using

 DNS to XOs)

^ I think this is both incorrect and unnecessary.

For correctness it should be DHCPDARGS=wlan0;

But as long as wlan0 is assigned to the 172.18.96.0 network then you do not 
need to limit the configuration to an interface.

What are you using for a configuration: 

-WAN - eth0 - XS - eth1 - switch - AP - XO?
-WAN - etho - XS - wlan1(1)- XO? In which case, what are you using to share the 
wlan connection?

When the XO does connect, what does it receive for an IP address?

Re: [Server-devel] Problemas con servidor xs

2012-04-04 Thread Reuben K. Caron
Fernando,

What you have done is a great test to show that the XS is correctly setup and 
working.

Now we have to make some changes. There are a couple ways to do this but I'll 
suggest one:

-Disable DHCP on XS
-Enable DHCP on 2wire
-Configure eth0 IP address on XS: 192.168.1.253 
-Configure on eth0 GATEWAY = 192.168.1.254
-Configure DHCP server on 2wire to point to 192.168.1.253 for DNS

The goal is for the XO to receive the following ip configuration:

IP address 192.168.1.1-252 (check by runinng ifconfig)
Gateway: 192.168.1.254 (check by running route and look at default gateway)
DNS Server: 192.168.1.253 (check by running cat /etc/resolv.conf)

Please let us know.

Regards,

Reuben

 Fernando,
 
 So from a TCP/IP standpoint everything appears to be functioning correctly. 
 If I am missing something that you believe is not functioning from the TCP/IP 
 layers please point them out. 
 
 You now have two issues:
 
 -DHCP clients (XOs) are getting the wrong DNS configuration. To resolve this:
 --On the 2wire, configure the DNS server to point to 192.168.1.253 (See 
 attached, I believe it is the correct screenshot form your link. The picture 
 shows a red box. The DNS configuration is two boxes above this)
 
 -The DNS server on the XS 0.6 will not answer DNS queries to 192.168.1.253. 
 To resolve this:
 --Change the configurations files of named, httpd, and ejabberd to bind their 
 services to 192.168.1.253, or
 --Install and Use XS 0.7 -- which resolves this issue by binding services to 
 all available addresses (recommended)
 
 Please discuss with the team and let me know more questions.

 The short version of it is: bitfrost is currently broken on 64 bits.
 
 This is what an XS based on CentOS x86_64 needs to run oatslite:
 
  - latest bitfrost.i686 (from an XO repo)
  - python.i686
  - an extracted python2.6 binary from python.i686 -- I used
 rpmdev-extract and installed the binary as /usr/bin/python2.6-i686
 
 Using python2.6-i686, oatslite now signs the messages correctly.
 
 The root cause seems to be a problem in the Pyrex bindings to
 libtomcrypt / TomsFastMath. Maybe ctypes would be better here.

 Good Day,
 
 Iam using a dell optiplex gx 240 as my OLPC school server(XS). In a 
 particular school we are rolling it out to, powercuts tend to occur 
 regularly. Do you know of a BIOS setting that enables the server to 
 automatically boot when the power comes back on? This would be much better 
 instead of us having to go down to the school to turn on the machine manually

Re: [Server-devel] Dansguardian on XS

2011-04-04 Thread Reuben K. Caron

German,

You are at a point where you must define your own public DNS server.  
Hosted at your own public IP address. On the following site we show  
the technique. The configuration is not exactly the same but similar:


http://wiki.laptop.org/go/OS_Builder/Adding_OpenDNS_Configuration#Configure_your_public_DNS_server

Basically, DNS queries would be: XO-XS-PUBLIC FOUNDATION DNS SERVER- 
OpenDNS


As your deployment grows this will also allow you to more easily scale  
your XS installations as they can be preconfigured to point to your  
managed DNS server, instead of trying to find the public IP address at  
each site.


I hope this helps.

Regards,

Reuben

Re: [Server-devel] Hibrid configuration for the XS-server|XS inside a network

2011-04-04 Thread Reuben K. Caron
Alvar,

You could also:

-Install on VM with one NIC
-When installation is complete run xs-swapnics.
-The one NIC should be assigned an IP on your network.
-Add a record in your DNS server pointing to the XS IP address on your  
network.

 Hi Alvar!

 Jerry Vonau has done some very good work on this track. I don't
 recommend at all a VM.

 Instead, install a vanilla F9, and then pick the packages you need
 from our XS rpm repo
 http://xs-dev.laptop.org/xsrepos/testing/olpc/9/i386/

 You'll probably need some bits from the xs-config package.

 I am trying to make this kind of setup easier in the next XS release

 Again, Jerry's work on that track is very helpful -

 In the Browse activity that you are using, it doesn't seem possible

I don't believe this is an XS issue. The XS is serving up the file and  
correct file type. I believe the solution lies in altering the mime  
type on the XO, so the XO will download the PDF and associate it with  
the Read application. FWIW, this is exactly how Browse used to work

OLPC purchased 30  machines for OLPCorps with the following specs from

   -HDD Standard: 160GB 3.5 Seagate SATA 7200rpm
   -Power Switch: None - Unit will be set to Auto-Power-On


 And anyone else that's running an XS (hi Hamilton!)... we need your hw
 profile and your numbers.

 Additionally, I've added a 'server sizing' section. It'll be great to
 get corroboration that the CPU/RAM to number of users match what you
 are using in the field, and whether your server gets in trouble when
 usage spikes.

Re: [Server-devel] specs for virtual machines

Hrmm, an interesting proposal. I'd be happy to talk to them. This of  
course would require a ~100% connectivity on site which may be more  
useful for SOAS deployment's but nonetheless it may be of some  
interest to OLPC deployments.

Not by default. The only way this can be achieved now is by backing up

we want real life users to do has to be doable with coursecreators and

 It had all been a theoretical exercise. Today, trying to figure out
 what the correct fix is to put it in an rpm I just cannot repro the

 The reason it 'Just Works' is that Apache is actually also listening
 on localhost. So Squid will gladly connecto localhost and issue an
 HTTP/1.1 request saying 'host'.

 Here is how I test that manually -- and apache replies nicely:

 Now, there is a number of changes (some of them trivial in appearence)
 in the apache configuration that could break the behaviour... have the
 local teams installed any extra software or added/changed
 configuration of Apache?

 None. The installation was done as follows:
 Install from USB XS0.6d2.
 Install using all defaults.
 /etc/sysconfig/olpc-scripts/domain_config olpc.corp
 /etc/sysconfig/olpc-scripts/TURN_SQUID_ON
 reboot
 The hardware had two nics, one on the motherboard the second a USB dongle.
 Motherboard NIC, WAN, was and is not connected to internet. USB Dongle, LAN,
 was connected, and gave DHCP addresses over wireless to APs attached to that
 port.

Re: [Server-devel] Server configuration

2009-06-01 Thread Reuben K. Caron
Neo,

Hi. I'm wondering why you need the Static IP. Does the XS have one or
two network cards? Will the XS act as a gateway to the Internet?

Thanks,

Reuben


Grape Projects IT wrote:
 Hi Martin,

 I have never setup a static address before and therefore have never had
 this issue before. Below is the step-by-step configuration that I followed
 and I am having a problem with the DNS as the XO's do not connect to the
 Internet

 I downloaded the XS 0.5.2 image and followed the instructions
 http://wiki.laptop.org/go/XS_Installing_Software.

 1.I initially ran the script /etc/sysconfig/olpc-scripts/domainconfig
 katane.org with katane.org being the hostname


 2.I also changed the HOSTNAME=localhost.localdomain to
 HOSTNAME=schoolserver.katane.org


 Our internet has a static IP address therefore I copied
 /usr/share/doc/xs-config-*/ifcfg-eth0-local.example to
 /etc/sysconfig/olpc-scripts/ifcfg-eth0-local and edited the file
 with the following:

 IPADDR=10.50.211.15
 IPV6ADDR=no
 NETMASK=255.255.255.0
 NETWORK=10.50.211.0
 BROADCAST=10.50.211.255
 GATEWAY=10.50.211.5

 I also edited the /etc/resolv.conf to resolve the DNS nameserver as follows:

 search katane.org
 nameservers 10.50.211.5

 3. Restarted the machine

 4. I then started the ejabberd service at runlevels 345
 5. Restarted the machine  shutdown -r now

 6. After reboot I pinged www.google.com and I got reply packets which
 meant that I had connection to the internet

 7. now the problem is that when I check the ejabberd status ejabberdctl
 status I get an error RPC failed on the node ejabb...@schoolserver:
 nodedown

 so I went back to my /etc/resolv.conf file and edited the nameserver back
 to 172.18.0.1 and restarted ejabberd and this executed with no errors. But
 now the server does not resolve the DNS addresses cause when I ping
 www.google.com I get the error unknown host www.google.com

 8.Another thing is that the XO does not connect to the internet under all
 scenarios but it connects to the schoolserver as I get to the who are
 you? page

 Now what do I need to do to make this work as I am using Active Antenna to
 connect the XO's to the Server

 Thanks Reuben,

 The part that I like is the hook to query a DB, with a bit of work the
 need to login could be removed, and just look up the group membership
 that the mac address has in the db.

 Just a thought,

 Jerry


Keep the thoughts coming! :-) Additionally, this solution would be more
secure as it does a dance with iptables versus the netreg way where a user
could simply assign themselves an ip in from the authenticated group and
gain access to the internet. Both solutions have their merit..first one to
program it into XS gets their pick..

something about that inside it.


Unfortunately, we we haven't set up a GUI, web browser, or emailing 
capabilities of any kind on the server itself so emailing the log file 
will be a roadblock for me.  I haven't worked in linux for about 5 
years now until trying to tackle this project.  I'm relearning how to 
do basic things like ls, pipe to less, and use vi for simple text 
edits.  Setting that stuff up is likely to take a lng time.  Is 
there anything specific I can do offline to find what you're hoping 
for inside.  In writing you this email I just recalled the existence 
of grep.  is there something I could grep for in the log file and give 
you some feedback on it? 

On  the subject of following instructions, there have been two of us 
working on the server, sometimes one at a time so I can't 
guarantee that we've followed them to a T, but we both believe that we 
have.  We've gone so far as to rerun the initial scripts, recheck 
hostname, reset the acl lines in ejabberd.cfg repeatedly, connect to 
the jabber server with 2 different jabber clients (which has been 
successful, we've chatted back and forth using our server. 


We just can't access the admin inteface at 
http://192.168.0.162:5280/admin, we keep getting 401 unauthorized), 
read every wiki page that sounded remotely relevant, etc.



Where is this IP coming from? How are you changing this?

Martin, also note (below) they have one nic.. Can you remind us what the 
default behavior is for one nic?


And we've been following hunches at each step so we have pulled some 
of the instructions out of related pages from the wiki.


I've been careful to comment out all of the original lines in the 
ejabberd.cfg file and mark all of my changes for easy resetting of 
each segment to it's original state.  Which I've since done.  So 
theoretically, the file should be in it's original state except for 
the {acl, admin {...   line that we added to give admin privs to our 
sample user.  

But of course, I could have made missed something.  However, the 
server is still working fine when we connect via 3rd party clients 
(pidgin pis), so I don't think I've done anything critical...


Let me know if I should grep anything out of the log file for you.

Thanks for the help!

  Hi,
 
  I am trying to get gadget working on my XS at
  schoolserver.solutiongrove.com
 
  First I downloaded the source and built it, but I could not
 find any
  indication that gadget was installed. How can I tell if it
 is working?
 
  Next I tried the gadget package
  http://koji.fedoraproject.org/koji/taskinfo?taskID=1261886
 RPM but it
  required ejabberd package. RPM says this is not installed.
 (I did
  install python-twisted which was another requirement of the
 RPM).
 
  Does anyoe have any advice on getting gadget working?


 Basically you have to install the gadget service, launch it
 (it's a
 separated process), modify your ejabberd.cfg as explained in
 the Gadget
 README and then restart your ejabberd.

 You can see if Gadget is working by looking at the XMPP
 traffic
 exchanged between clients and the server.

 Gadget started /etc/init.d/gadget start

 Ciro,

 On the XO side you need to make sure the XO is connected to an Access Point 
 that is connected to the XO, like:

 XS---AP---XO

 Once the XO is associated with the Access Point. You can register the XO to 
 the school server. You can do this on the Home Screen. Hover the mouse of the 
 XO Child, and select the option to Register. On 703 you can check if 
 registration is successful by moving the mouse away from the XO Child and 
 moving the mouse back over the XO Child and check if the Registration option 
 is now gone. On newer versions, 8.2.x, a registration success message will 
 appear.

What version of XS are you working with? Have you followed the

Specifically, have you made sure ejabberd is running, service ejabberd

Whenever we try to register one of the XOs, we get a message that we

However, we can ping the server from the XOs and the XOs from the server.

Any ideas?

 Hi,

 My name is Vivek Pai and I'm new to the list. Forgive
 me if I'm missing anything relating to this query.

 A long time ago, I visited OLPC to discuss HTTP proxy
 needs for the schools, and our research group at Princeton
 had a project that looked like it might be a good fit. In
 particular, it's a Web proxy that scales to large storage
 sizes without requiring large memory consumption. It can,
 for example, use a 1TB USB drive as a store, while requiring
 only a XO-class laptop to drive it.

 Is there interest in something like this for the XS server?
 We're also working on a WAN accelerator that uses this
 proxy, providing transparent compression of content, even
 for dynamic Web sites.

 The original ticket for this was

 Just need to know where I'm at before I start to play

   

 With a the game keys depressed I see that the XO is looking for
 http://172.18.0.1/fs.zip, I assume that is the path for the
 staging/upgrade images to be downloaded and installed from? If so, I
 should be able to dump the image (fs.zip and version.img) that I want to
 load into /docroot of the schoolsever and the XO should be updated
 automatically?

If you setup an AP with SSID: OLPCOFW connected to a computer with IP
172.18.0.1 with fs.zip and image file at the root of the webserver, yes
it will work; albeit slowly..

David,

Thank you for the information.

Can you attempt to perform a clean install again with edits in line below.

David Leeming wrote:
 Hi Reuben

  

 -  Installed 0.5 Nov 19th download on Toshiba notebook computer with
 black box prototype AA (USB)

 -  Fresh install (overwriting not upgrading the previously fully
 working 0.4 installation

 -  Set location Guadalcanal, use local time
   
(I did not change this in my tests; I doubt this has any effect but want
to note I left this at the default setting)

 -  No optional application selected

 -  Install.. restart

 -  /etc/sysconfig/olpc-scripts/domain_config oceania.org
   
After running domain_config

Then edit the file /etc/sysconfig/network and set hostname to
schoolserver.oceania.org (nano /etc/sysconfig/network)

Then restart (shutdown -r now)


 -  chkconfig --level 345 ejabberd on

 -  service ejabberd start

   
Wait a few minutes for ejabberd to completely startup. You can check
it's status by running: service ejabberd status

 -  ejabberdctl register admin schoolserver.oceania.org admin 

   

With a fresh install of 0.5.1 dev 3 you don't need the following from
here --
 -  restart

 -  yum --enablerepo=olpcxs-testing update

 -  restart

   
to here --

 -  One one of 4 XOs, log onto ejabberd web admin and set up shared
 roster Online

 -  restart

 -  start all four XOs and register, then restart

  
   
On the XOs are registering from a fresh OS install, 8.2? If the XOs have
been previously registered; you will need to clean out their
registration by removing the server fields in
/home/olpc/.sugar/default/config.

After removing these fields; restart the XOs
Then connect the XOs to the appropriate SSID or AA.
Then register the XO.
Then restart the XO.

I hope this helps. Please let us know.

 At this stage I cannot see any other XO, and still had to do the work around
 of removing all four users from the ejabberd webadmin and restarting
 everything before I could see them in the neighbourhood views.  (as advised
 by Martin):

  

 (Martin wrote...) To avoid re-installing the XS to re-test the just
 registered scenario you can

  - go with a webbrowser to the ejabberd admin panel, go into the
 'schoolserver' vhost listed there and delete all the users registered

  - restart ejabberd

  - restart the laptops

  

 This happens each time a laptop is restarted. 

  

 However, once all going, it is fine: 

 - All four show up in the eJabberd control panel as users

 - All have the same correct results for olpc-netstatus 

 - I tried sharing Memorize - all four OK

 - Video chat is OK between any two

 - Server access and Internet browsing all OK (updated them each online)

Let me detail my steps

Appended upgradeany- ran default install

Ran xs-swapnics

Check var/log/messages found (snipet):

Reviewed dhcpd-xs.conf file: It did not have a declaration for 172.18.96.*

I reviewed /etc/sysconfig/olpc-scripts/dhcpd.conf.1 - It did not match
dhcpd-xs.conf

I ran ./network-config 1
I ran ./domain-config xs4.org (i know it isn't xs4 but I'm maintaining
domain for posterity)

Rebooted.

dhcpd-xs.conf now has the declaration for 172.18.96

DHCP is started but still does not hand out an IP.

 Has anyone gotten eth1 on XS 0.5 working?
 

 I have, at least on 4 different bits of hw, but I worked on it too
 much to be a good tester of it. Others have installed successfully.

 One thing that 0.5 has is that it almost always picks the ordering of
 the NICs _in reverse_ of what 0.4 did. So perhaps your NIC identities
 are reversed? You can test changing the ethernet cables around or use
 xs-swapnics (and then reboot).

 Other than that, I'm a bit lost. Can you get any output from calling
 ethtool eth1 ? What's the physical hw? It's also possible (though
 unlikely) that F9 has bad drivers for your specific hw...

Great, thanks. I was steered to the correct files and got it to work from
both the USB and command line. The files I used can be found at:



 Cool. Are you doing this on xs-0.5? If you update to the newest rpms
from the olpcxs-testing repo you'll get a nice chime indicating that
it started, and another nice chime meaning I'm done.

  
I'm using xs-0.4. I'll look forward to that feature in .5 as the chime 
will be much nicer then monitoring the progress of 
tmp-xo-builds-pub/builds.

Out of curiosity why do we require the tree files which come from:
http://pilgrim.laptop.org/~pilgrim/xo-1/streams/8.2/build767/devel_jffs2/



I'm just following what Scott did for his own rsync updater server. I
didn't get into the details of why -- as a matter of expediency, I did
my bit of cargo-cult programming there :-)

In other words: monkey-see, martin-do
  

ah ha! gotcha, thanks.
