First route the loopback, then the net, and finally, the various IP addresses starting with the default (originally allocated) one: /sbin/route add -net 127.0.0.0 /sbin/route add -net 172.16.3.0 dev eth0 /sbin/route add -host 172.16.3.1 dev eth0 /sbin/route add -host 172.16.3.10 dev eth0:0 /sbin/route add -host 172.16.3.100 dev eth0:1 /sbin/route add default gw 172.16.3.200 Enjoy, Ravi Ravi Kumar Munnangi wrote: > I want to give more than one IP addresses to my NIC. > For this we have to enable the feature of IP alias > when configuring the kernel and recompile it. > Is there any way to check if the option is already > checked or not? > My next question is, > After reconfiguring and recompiling, how can I give > IP addresses(aliases) to NIC? > please tell me the commands to be used. > > Ravi kumar > > __________________________________ > Do you Yahoo!? > SBC Yahoo!
