Re: [Server-devel] Collaboration unreliable 0.5
2008/12/14 David Leeming leem...@pipolfastaem.gov.sb This is intermittent; 30 mins ago I did have 3 out of 4 showing, but after rebooting everything and waiting 30 mins, still no sign of any. My user group helping me test XS 0.5 has noticed the same issue. It's not limited to XOs in the neighborhood view, either. Several of us use other chat clients like finch, pidgin, gajim, and adium (on the Mac), and the buddy list in those does not reliably populate. Luckily we had already established the convention of a permanent MUC named chat, which no one had trouble joining. There, at least, we could see and chat with everyone fairly reliably. That is not an acceptable solution for children, of course. Our theory was that ejabberd isn't pushing out all the roster data to other connected users or there's a longer time interval in between pushes. We noticed if we stayed on long enough, eventually more folks would show up in the buddy list or the XO network home, but it seemed competely random. I think it's gotten better lately, but that's probably subjective.

Re: [Server-devel] Collaboration unreliable 0.5
Hi I am using USB active antenna (prototype). Has always worked well with 0.4. I concur with Anna that if you leave them connected, after considerable time they do partially populate. I have run olpc-netstatus on all four laptops, making first certain that: - all are connected to School Server - all appear in eJabberd as online users - none appear in network neighbourhood (you can't see any on any laptop) 15 mins+ after first connected Remember, they are all registered and running 8.2 The olpc-netstatus shows the following: On ALL the four XOs: - Correct m0odel, serial, MAC - Build 767, Firmware CL1 Q2E18 Q2E - Libertas: 5.110.22.p18 - Correct Nick, uptime - IP msh0 172.18.10.2 (3,4,5 i.e. the four XOs) - DNS 172.18.0.1 - Telepaphy gabble - Jabber school.oceania.org - XOs 2 - Essid olpc-mesh - Channel 1 - School school.oceania.org - Config School Mesh Note, in eJabberd the server name is shown as schoolserver.oceania.org not school.oceania.org and the domain name was configured on the XS as schoolserver.oceania.org (that's also what the hostname is in the /etc/sysconfig/network file) David Leeming OLPC Coordinator, SPC and Technical Advisor, People First Network Honiara, Solomon Islands -Original Message- From: Martin Langhoff [mailto:martin.langh...@gmail.com] Sent: Tuesday, 16 December 2008 2:52 a.m. To: David Leeming Cc: XS Devel Subject: Re: Collaboration unreliable 0.5 On Sun, Dec 14, 2008 at 7:59 PM, David Leeming leem...@pipolfastaem.gov.sb wrote: I apologise if this issue has already been dealt with on this list.

[Server-devel] Collaboration unreliable 0.5
I apologise if this issue has already been dealt with on this list. I have some problems reliably getting collaboration working when using server version 0.5. I have been using a laptop with an USB active antenna and after a few attempts managed to get 0.5 working and configured with no errors. The hostname was changed in the /etc/sysconfig/network file, eJabberd configured and started, shared roster group Online created, XOs registered. Over the past couple of weeks I have noticed that collaboration is intermittent. This is the scenario: - I have XS 0.5 running as above, with four XOs (two XO-1s and two B4s, all running version 8.2) - Four XOs are all connected to school server and show IP addresses in range 172.18.10.2 - 5 - I can ping between all XOs and to/from XS - I can ping the fully qualified domain name - I can log onto eJabberd admin from an XO and see four online users, all are registered - I can see the Who are you pages in the browser on all the XOs So, eJabberd appears to be working OK, but none of the XOs show any others in the neighbourhood view. This is intermittent; 30 mins ago I did have 3 out of 4 showing, but after rebooting everything and waiting 30 mins, still no sign of any. I have used the same set up exactly with XS version 0.4 and it's all solid - the neighbourhood view fills up rapidly after connecting. What's causing the unreliability with 0.5?
