Multiple ip's for same NIC

hvdwatt · 06-16-2003, 04:40 PM

How do I assign multiple IP's to the same NIC?

I have setup DHCP and can assign IP's to all my machine on my home network but want to give multiple ip's to the same NIC connected to the Internal network.

What do I do. Please help.

Thanks

Hendrik

have the same problem, so i guess this is not reply you can use. command /sbin/ifconfig eth0:0 xxx.xxx.xxx.xxx creates a new IP without any problem but after reboot it is gone. maybe i am missing something, need this for virtual host configuration in ProFTPD. just doing more search...

svejk you need to run the command everytime you boot up your computer

for slack check /etc/rc.d/rc.init1 or rc.init2.. or else you can add the command to any file you want as long as it loads at startup

For RH I found you can also create additional files in /etc/sysconfig/network-scripts/

eth-cfg0:0
eth-cfg0:1
eth-cfg0:2 etc...

Just Vi/Emacs (I aint starting a debate) in and cp the original then mv rename it pop in and bind the extra ip address then when you start - hey presto!

Hope that helped
