IP-Aliasing

[Frank Hempel <red_socks@gmx.de>]

Hello,

I don't get IP-Aliasing to work. The machine has got one interface 
(eth0) working correctly with ip=192.168.1.1
Issuing the commands

ifconfig eth0:1 192.168.1.100
route add -host 192.168.1.100 dev eth0:1

brings the interface eth0:1 up, but I can't ping it from the same 
machine or other ones.


An odd thing I noticed is the ifconfig output:

eth0      Protokoll:Ethernet  Hardware Adresse 00:0B:6A:78:EB:25
          inet Adresse:192.168.1.66  Bcast:192.168.1.255

It doesnt show the RX/TX etc. lines for the eth0:1.

Could someone give me a hint on how to do it right?

Thanks, Frank.
