Hi everyone,
I'm running into a problem adding more than a couple aliased interfaces to my eth0 interface. I'm running Mandrake 8.1 and I've copied my /etc/sysconfig/network-scripts/ifcfg-eth0 to ifcfg-eth0:0 ifcfg-eth0:1 ifcfg-eth0:2 and they come up fine after I change the DEVICE and IPADDR lines. but when I tried to create ifcfg-eth0:3 and ifcfg-eth0:4 entries them will not start at all. If I reboot, they don't show up.

here's what I get from ifup eth0:4

[root@la2fire network-scripts]# ifup eth0:4
Device "eth0:4" does not exist.
Cannot find device "eth0:4"
Error adding address x.y.z.39 for eth0:4. (I changed the x.y.z)
WARNING: interface is ignored: No such device
[root@la2fire network-scripts]#

here is the text of the the ifcfg-eth0:4 file:

[root@la2fire network-scripts]# more ifcfg-eth0:4
DEVICE=eth0:4
BOOTPROTO=static
IPADDR=x.y.z.39
NETMASK=255.255.255.224
NETWORK=x.y.z.32
BROADCAST=x.y.z.63
ONBOOT=yes
[root@la2fire network-scripts]#

I can manually issue a "ifconfig eth0:4 x.y.z.39 broadcast x.y.z.63 netmask 255.255.255.224"
and the interface comes up fine. There was no problem creating the first bunch of aliases (eth0:0-eth0:2)
Any idea what's going on?
Thanks!

hi ,

at the fron it does seems that there migt be limitation to the number of limitation to the number of aliases that one can have .... but well i cant recollect to any such limitation ....
Do u have firewall (such as iptables or ipchains ) installed on ur machine ? if so is the script being exec from ifup script ?

It looks like a ROUTING problem to me. Check out ur ifup script and u will see a line that reads like below :

echo $"Error adding address ${IPADDR} for ${DEVICE

if u know basic shell scripting i think u will be able to trace the error mesage to the actual culprit

NOTE: since iam a RedHat person i maybe be wrong with the above solution but u see a few other mandrake users have had similar complaints.
