Assuming the qmaster is up and running, and your hosts don't have
conflicting firewalls. I think your name resolution might be broken. You
have to be able to address the master from the host machine and have the
master recognise the host. This means all hostname/reverse IP lookups
must work consistently and probably match any names used in the
configuration. It might help to run the conf.sh command manually to see
what error messages it spits out - the setup script throws away any output.
