XS Troubleshooting
ejabberd and your hostname
For the ejabberd service to run, the name of the ejabberd server (in our case "schoolserver.example.org") must be resolvable to it's IP address (e.g. DNS server alias records). You will encounter problems if the hostname is not resolved correctly by the upstream authoritative DNS server for your domain, or if it is not resolved at all.
A good test is:
ping `hostname -f `
Hostname has been changed after initial configuration
Note: only for 0.4 and 0.5.x.
If you change the hostname of the XS, ejabberd will break. This is be fixed in XS-0.6, for earlier releases, do not change the hostname unless you are willing to handle the breakage yourself.
To change the hostname after ejabberd has been started initially, use this process:
- Stop ejabberd
ejabberdctl stop
- Use the 'domain_config' utility to set the name
- Update the fully qualified hostname of the machine by editing /etc/sysconfig/network as follows:
HOSTNAME=schoolserver.newdomain.org
- Ensure the hostname is what you want and resolves correctly when doing
ping `hostname -f` - Stop ejabberd
ejabberdctl stop
- Empty the /var/lib/ejabberd/spool/
rm /var/lib/ejabberd/spool/*
- Start ejabberd
ejabberdctl start
You now must re-create the 'admin' account and 'Online' group as described in XS_Installing_Software_0.5
