Chaning the subnet on Linux and Solaris boxes

[DanTheMan]

Hey,

Quick question. If you're changing the subnet mask of a solaris box and also linux (RH) which files to you have to edit locally?

Don't know about RH but on Solaris it should be /etc/netmasks if you only edit the file you'll need to restart the network service or reboot. Otherwise change the netmask on the interface manually, then change the file and it will be permanent.

On linux, go to /etc/sysconfig/network-scripts and edit the ifcfg file that relates to your network adapter. Then run '/etc/init.d/network restart' and you should be good to go.

OK these servers will be connected to a new switch which I'll need to the host file (/etc/hosts on both OS's.....?) and I gather that each network interface has its own host file too; /etc/hosts.hme0 for example.

Or you could use the ifconfig command, do 'man ifconfig' for info.

Some boxes also have the 'ip' command, again 'man ip' is your config.

Almost..Solaris you have e.g. /etc/hostname.hme0 (literally hostname not the actual hostname) which contains just the hostname, one file for each interface/sub interface
The IP gets looked up from /etc/hosts ...just got the one /etc/hosts

That's as well as the netmasks *points a few posts up*


Best to just lose the RH box all together while you're at it, put a proper OS on it instead TROLLTROLLTROLL
