LinuxQuestions.org - Hang during boot due to network problems

Hi,

Hopefully this will be trivial!

I'm have been moving servers between two data centres, but during the work the network configuration in the new data centre had been setup incorrectly (wrong VLAN) with the result that my servers could not ping their new gateway despite having a new correct config in /etc/sysconfig.

So, when I booted the servers and watched via the ILO they all started networking OK and then either hung trying to start NFS or Sendmail. Back in the day, when I was using HPUX, this would not have been a problem - <CNTL><C> or forcing a core dump would kill the service trying to boot and it would proceed to a login, from where the issue could be fixed.

On my RH5.7 servers though <CNTL><C> does nothing. That necessitates a reboot (with memory check - yawn, boot into single user mode, resolve problem and reboot). Should <CNTL><C> do something useful or is it the iLO getting in the way? Or can I jump into another session somehow like during a build?

It really is a pain to waste all this time rebooting when I have a bunch of people waiting on me to complete. I've tried googling this problem, but all the hits talk about is how to solve the underlying network (or other service) issues, but that doesn't interest me. I just want to know how to abort a service during boot from the iLO, or how to work around it.
