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.

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

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

ifconfig ... netmask 255.255.255.0

so the command syntax will be like :

ifconfig 10.10.1.1 netmask 255.255.255.0 right?

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.
