IP multiplexing in Linux 7.2

[S.C. Fun]

Hey Guys, I'm a newbie in Linux. Any idea how to configure IP multiplexing in RH Linux 7.2? Thanks in advance.

Hi,

you can set multiple ip addresses to one pysical port. (max 255)

The first port is, as you know, eth0.
The 2nd one is eth0:0

So if you want to set 2nd ip to the card,
# ifconfig eth0:0 ip-address-0 netmask xxxxxx

the third one
# ifconfig eth0:1 ip-address-1 netmask xxxxxx

If you want to set the address into the config file, assuming you are using RH,
#cp /etc/sysconfic/ifcfg-eth0 /etc/sysconfig/ifcfg-eth0:1
then edit the file.

After you change the config file, # /etc/rc.d/init.d/network restart will restart your NIC.

good luck
