If you're looking for how to run your own Jabber server for remote Mesh sharing, you want the Jabber server page.
If you would like to change which Jabber server that your XO (or emulated XO) is currently using, you want the Sugar Control Panel.
If you want to display your jabber contact details on your user profile to chat with other OLPCians, see Template:User_Jabber
Community Jabber Servers
There are a number of community jabber servers available for your XO. Visit Community Jabber Servers to see the full list.
Connecting to a community jabber server
Open Terminal, then type the following commands :
sugar-control-panel -s jabber jabber.server.url
replace jabber.server.url with the jabber server you with to use
then restart Sugar (warning: first close your activities to save them!) by pressing ctrl+alt+erase - then go to the neighborhood view and have fun!
Mixing OLPC and non-OLPC clients
In OLPC Release 8.2.0, non-Sugar IM clients (like Pidgin) that are registered on the Jabber server don't show up on the XO Sugar Neighborhood View, but the XOs (and other Sugar clients) will show up in the buddy list of your IM client. You can initiate a Chat from the IM client to an XO, which will show a Chat invitation on the frame. If that is accepted, you can chat from your IM client to the XO.
In the next release (OLPC 9.1 or Sugar 0.84), non Sugar IM clients should automatically show up on the Neighborhood View. In the mean time someone has suggested this workaround to show your IM client on a Sugar Neighborhood View:
Send the following IQ:
<iq type="set" id="18" email@example.com'> <pubsub xmlns="http://jabber.org/protocol/pubsub"> <publish node="http://laptop.org/xmpp/buddy-properties"> <item> <properties xmlns="http://laptop.org/xmpp/buddy-properties"> <property type="str" name="ip4-address">X.Y.Z.Z</property> <property type="bytes" name="key">AAAAB3Nz....WiHx5Rqfg=</property> <property type="str" name="color">#00bF00,#a0000</property> </properties> </item> </publish> </pubsub> </iq>
This lets Sugar pick you up. Where X.Y.Z.Z. is your IP address; the Key is just about anything (but take the key from your ~/.ssh/*.pub file to stay within the spirit) and the colours are the usual RGB triples; one for the inside and one for the outside (i.e. the example is dark green with dark red.
