Smile Change Netmask permanently from the Command Line


How do I change the network mask from the command line permanently. I can't get access to the desktop at the moment hence the question.

I'm running SLES8

Thanks

edit the ifcfg-eth0
in FC this is present under /etc/sysconfig/networking/devices
In SUSE I think its under
/etc/sysconfig/network/
and restart network (see man ip or man ifconfig)

Thanks,

You were bang on with the file location. I wasn't able to find out how to restart the service, which is a bit of a pain. I can restart the server of course, but I was hoping to avoid that.

If you have any ideas, let me know.

You can use either ifconfig with something like 'ifconfig <your_interface_here> address <your_IP> netmask <netmask_IP> broadcast <broadcast_IP> up' or edit as root the /etc/network/interfaces file and set the netmask there.

if you do a ifdown or ifconfig down etc etc you tend to close the network connection (unless you have another card)
and you wont be able to login unless you go there and up the network (just warning as I have done that stupidity once.)
I think service network restart should be helpfull
