Description Bryce Nesbitt 2006-09-15 19:15:29 UTC

I have a primary eth0, and eight alaises (eth0:0-eth0:7).

If I set ONBOOT=no for the aliases, it is INCORECTLY brought up on reboot.

[root@14252-24879 network-scripts]# cat ifcfg-eth0
# Intel Corporation 82541GI/PI Gigabit Ethernet Controller
DEVICE=eth0
BOOTPROTO=static
ONBOOT=yes
IPADDR=216.93.188.133
NETMASK=255.255.255.240
GATEWAY=216.93.188.129

[root@14252-24879 network-scripts]# cat ifcfg-eth0:1
# Intel Corporation 82541GI/PI Gigabit Ethernet Controller
DEVICE=eth0:1
BOOTPROTO=static
ONBOOT=no
IPADDR=216.93.188.135
NETMASK=255.255.255.240
[root@14252-24879 network-scripts]# cat ifcfg-eth0:6

# Intel Corporation 82541GI/PI Gigabit Ethernet Controller
#DEVICE=eth0:6
#BOOTPROTO=static
#ONBOOT=no
#IPADDR=216.93.188.140
#NETMASK=255.255.255.240
[root@14252-24879 network-scripts]#


After boot I see:

Comment 1 Bryce Nesbitt 2006-09-15 19:21:12 UTC

Marking as priority HIGH, because IP address conflicts can take down critical
services (the mess can get really big really quick).

Note:

Manually running ./ifup eth0:5 boot
does the right thing.  And the initscript looks fine too.

But rebooting is the acid test, and that's simply not working as expected.  I'm
not sure the exact code path.

Comment 2 Bryce Nesbitt 2006-09-15 19:21:39 UTC

I'm hoping for a patch to fc5, available via yum...

Comment 3 Bill Nottingham 2006-09-15 19:32:51 UTC

ONBOOT is not a valid option for aliases - you want ONPARENT.

Comment 4 Bryce Nesbitt 2006-09-15 19:59:39 UTC

Then convert it to a suggestion:
   ONBOOT=no
Is more orthoganal, and easier for sysadmins to grasp.


Where is ONPARENT documented?
    man ifup
Did not work.

# This script goes out of its way to arrive at the configuration of ip
# aliases described in the ifcfg-$DEV:* and ifcfg-$DEV-range* files from
# whatever existing configuration it may be given:.

Comment 5 Bill Nottingham 2006-09-15 20:05:11 UTC

It's documented in sysconfig.txt.

Comment 6 Bryce Nesbitt 2006-09-15 20:34:27 UTC

ok, found it, thank you.
