Howto change the Hostname of a RHN Satellite server (Spacewalk Server)
1) you need to change the server to the new IP adress / hostname. I advise to do this in single user mode from the currently running state.
Note: Don’t use UPPERCASE in the hostname. Satellite doesn’t like that !!!
telinit 1 hostname NEW_HOSTNAME vi /etc/sysconfig/network
#change to the new hostname
If you need to change the IP Adress then do so here now.
service network restart
2) DO NOT REBOOT
continue here ….
Follow the instruction on the screen to reset the hostname. It will do the rest for you
