Hello,

We have recently migrated our network from a 192.168.3.0/255.255.255.0
network to a 192.168.128.0/255.255.128.0 network, and since doing so, our
qmaster will not start.

We keep getting the following:

======================================================================
[root at stg2 sge]# /etc/init.d/rcsge start
   starting sge_qmaster
critical error: can't check for running qmaster: can't resolve service
"sge_commd/tcp"
   starting sge_schedd
error: can't resolve hostname "stg2.domain.co.uk"
error: can't get configuration from qmaster -- backgrounding
   starting sge_execd
critical error: can't enroll to commd: CANT GET SERVICE
[root at stg2 sge]#
======================================================================

Does anyone know what is causing this?

I have even tried a global find and replace of the old IP address range
for the new IP address range, but it still doesn't startup.

I'm getting desperate now, and have no ideas left, so any suggestions are
gratefully received! :-)

Just for the record, the same user on the same machine in the same
terminal *can* resolve stg2.domain.co.uk, as below:

======================================================================
[root at stg2 sge]# host stg2.crl.toshiba.co.uk
stg2.domain.co.uk has address 192.168.144.2
[root at stg2 sge]#
======================================================================

And yes - i've also tried adding stg2.domain.co.uk to /etc/hosts, but the
qmaster just will not start.

Please help! :-)

Thanks in advance,
Richard.
