[gentoo-dev] mysterious Problem

[MadCoder]

I want my eht0 card to accept two ip.

so, I use this config :

face_eth0="129.104.221.165 broadcast 129.104.221.255 netmask 255.255.255.0"
iface_eth1="192.168.1.1 broadcast 192.168.1.255 netmask 255.255.255.0"
alias_eth0="129.104.221.100"

but there is a big problem : the alias_eht0 has netmask 255.255.0.0 by default 
!!!

how can I specify, that I want netmask=255.255.255.0 ?
and why isn't it the default choice, since i'ts the netmask of face_eth0 ?

Umm, maybe this is just me, but why not just do:

alias_eth0="129.104.221.100 netmask 255.255.255.0"

?

Dirty workaround, add a line where you configure the interface with it's
alias (using ifconfig) to your rc.local, that way you can specifiy
whatever you want as if you were using the ifconfig command.

that's allready what I'm doing with a

ifconfig eth0:1 129.104.221.100 netmask 255.255.255.0

but on my Debian, when I create an alias, it always takes the same netmask 
than the main adress. So I was a little surprised.

You could always use the iproute2 commands if you have them installed -- eg:

 ip addr add dev eth0 129.104.221.100/24

The above adds the address 129.104.221.100 netmask 255.255.255.0 to eth0 (I think this is equivalent to an alias when using ifconfig).
