IP alias

Hi All,

I have gone through the forumn for ip alias and found the below entries for the temporary settings.
ifconfig lan0:0 netmask
ifconfig lan0:1 <2nd IP Address> netmask

what is the difference between netmask and subnet mask. Is netmask is called the broad casting address.

Re: IP alias

In the command above netmask is flag on the command to specify the subnetmask. Refer the man page for ifconfig.

Re: IP alias

"netmask" is the keyword here, is the value, e.g.

ifconfig ... netmask 255.255.255.0

Hope this helps!

Torsten.

Re: IP alias

so the command syntax will be like :

ifconfig 10.10.1.1 netmask 255.255.255.0 right?

Re: IP alias

Something like

ifconfig lan1:1 10.10.1.1 netmask 255.255.255.0


but make sure to choose another subnet compared to other NICs in this server.

Hope this helps!

Torsten.
