Adding IP addresses

[vdumatol]

Help me please!

We are running out of IP addresses and we just need to know the best way to do it. Our network is 10.1.1.0 - 10.1.1.255 and subnet mask of 255.255.255.0. Our Main Novell server is also our Groupwise server and DHCP server and it is at 10.1.1.48. There is a second nic that is not getting utilized in this server. We have tried changing the subnet mask to 255.255.0.0 and gotten this to work except for a Unix server that we don't know how to change the ip subnet mask so it stays in the network so we had to change it all back.

What i'd like to do is utilize the 2nd nic and find out what is the best way to go about doing this. Once we get the Unix server problem fixed can i just bind tcp/ip to this 2nd card using for instance 10.1.2.48 subnet mask 255.255.0.0 (also changing all the subnet masks of the old system) and then have half the people connecting to a different switch hooked up to that nic and have people get their groupwise and everything else from 10.1.2.48?

Or if someone has a better way please help.

what flavor of Unix?

if you know the name of your interface type the cmd below? I am using "hme0".

change subnetmask:
ifconfig hme0 netmask 255.255.255.0

change ip address of nic:
ifconfig IP 10.3.2.111

some flavors have files:
/etc/netmask
/etc/defaultrouter
/etc/hosts

Good Luck!
