Re: Virtual IPs...

[Bob Plagens <bob unix tfs net>]

I don't know of any FAQ's on the subject, but here is the method
we are using to do ip aliasing:

First, you need to compile IP Aliasing support into your kernel.

Then you need to use 2 programs, ifconfig and route.  For each IP
address you want to alias, you need to use this pair of commmands

/sbin/ifconfig eth0:n xxx.xxx.xxx.xxx
/sbin/route add -host xxx.xxx.xxx.xxx dev eth0:n

I have placed all of my alias pairs into a file called rc.alliases,
located in/etc/rc.d and run at boot time.


As an aside, I have heard that without source modfications, there is a
limit of 255 aliased IP addresses.  Can anyone verify this?
