ifconfig aliases

Post by James Ker » Thu, 15 Jan 1998 04:00:00



In Red Hat 4.2, it appears that only 30 ifconfig aliases are supported
out of the box.  What is needed to increase this number?  Does the
kernel have to be recompiled, or is there some system configuration
variable that needs to be changed?

Thank you,
Jim Kerr

  It does more than that (up to 255 or 256 I think) but ifconfig just
shows the first 32 interfaces I think.  Try "ifconfig eth0:32" and it will
show you that alias if you've defined it.

Not true.. ifconfig doesn't report more then 31 aliases. Use netstat -r,
instead, we have 210 IP running.. on a single linux box. We don't want to
find out if it breaks after 254 IP(using 2 C clases to assign IP from), so
we spliting the box up :).

1. Help needed with ifconfig alias

I am using FreeBSD and I am wanting to have my machine listen to
two ip addresses (Or more).  I have read that ifconfig can help me
accomplish this, but all the docs I have read say that it will but
do not say how.  Therefore it is either trivial or hard as hell.
thanks
