Sorry for what must be a really silly question.
Working on a RH ES3 box that some one else has already worked on. I reconfigure the network cards using the ifconfig command. I also add a couple of vlans using the vconfig command. Everything looks good but when I reboot it goes to back how it was when I started.
I know it's something to do with the files that live in /etc/sysconfig/network-scripts
Here's what would be great though - is there a command that will let me do the equivalent of the old Cisco - copy running-config startup-config - rather than have to muck about with a load of text files.
