[Server-devel] ejabberd errors after install: RPC failed on the node . . . nodedown

[Bryan Berry]

Hey guys, installed OLPC XS_163 today and everything went smoothly,
except ejabberd. Installed XS_163 bc haven't had a chance to play w/ any
newer builds and the install site is a ways from my office. Don't want
to have to go there too often.

did all the dns stuff before starting ejabberd

*but* hostname was schoolserver not schoolserver.doelab.schoolnet.gov.np
when I ran the "hostname" command it just puts out schoolserver

setting up ejabberd:
changed hostname to fqdn hostname in /etc/ejabberd/ejabberd.cfg
chkconfig --level 345 ejabberd on 
service ejabberd start

ejabberdctl register jtest schoolserver.doelab.schoolnet.gov.np password
RPC failed on the node register at schoolserver: nodedown

Then tried the following:

/etc/init.d/ejabberd stop
killall epmd
rm -rf /var/lib/ejabberd
rpm -e --nodeps ejabberd
yum install ejabberd
Fix config files, set hostname to my hosts fqdn, put in user jtest
Start ejabberd

ejabberdctl register jtest schoolserver.doelab.schoolnet.gov.np password

same bloody error msg:
RPC failed on the node register at schoolserver: nodedown

ideas anyone?
