Bug 14636 – IP-aliasing does not work

• Status: RESOLVED TEST-REQUEST
• Product: Gentoo Linux

[Description Ole Tange 2003-01-27 13:03:21 UTC]

I did: 
 
emerge rsync 
emerge -u world 
 
Then I made the following net.eth1: 
 
iface_eth1="dhcp" 
dhcpcd_eth1="-t 20" 
alias_eth1="10.0.0.88 192.168.1.88" 
broadcast_eth1="10.0.0.255 192.168.1.255" 
netmask_eth1="255.255.255.0 255.255.255.0" 
 
This should result in: 
eth1: 192.168.1.24/255.255.255.0/192.168.1.255 (via dhcp) 
eth1:0: 10.0.0.88/255.255.255.0/10.0.0.255 
eth1:1: 192.168.1.88/255.255.255.0/192.168.1.255 
 
but it does not. 
 
It seems 'net.eth1 restart' does the following ifconfigs: 
eth1:0 down 
eth1:1 down 
eth1:0 10.0.0.88 broadcast 10.0.0.255 192.168.1.255 netmask 255.255.255.0 
255.255.255.0 
eth1:1 192.168.1.88 broadcast 10.0.0.255 netmask 255.255.255.0 
 
The 3rd is definitely wrong and the 4th seems bad as well (wrong bcast).

This is what I get with baselayout-1.8.6.4 and your alias config on eth0:

that fix it, ole?

[Comment 4 Ole Tange 2003-03-16 15:43:11 UTC]

Nope. Exactly same error. 
 
I did: 
 
emerge sync 
emerge baselayout-1.8.6.4.ebuild 
(emerge -u world will not work, as I have a pre-release of xfree installed) 
 
I tried substituting /sbin/ifconfig with a script to see what parameters it was called with.. 
 
ifconfig eth1:0 10.0.0.88 broadcast 10.0.0.255 192.168.1.255 netmask 255.255.255.0 
255.255.255.0 
ifconfig eth1:1 192.168.1.88 broadcast 10.0.0.255 netmask 255.255.255.0 
 

[Comment 5 Martin Holzer (RETIRED) 2003-03-18 17:21:17 UTC]

how about etc-update ?
are all scripts up2date ?

[Comment 6 Ole Tange 2003-03-19 03:31:25 UTC]

yes. all etc-scripts are updated. 

[Comment 7 Martin Schlemmer (RETIRED) 2003-03-30 14:03:46 UTC]

Please attach your net.eth0.

[Comment 8 Ole Tange 2003-03-30 14:36:32 UTC]

I just tried removing net.eth0. And the problem still exists: 
 
# /etc/init.d/net.eth0 stop 
 * ERROR:  "net.eth0" has not yet been started. 
# /etc/init.d/net.eth1 stop 
 * Bringing eth1 down... 
 *   Waiting for dhcpcd to shutdown.....done                              [ ok ] 
# /etc/init.d/net.eth1 start 
 * Bringing eth1 up...                                                    [ ok ] 
 *   Adding aliases... 
 *     eth1:0... 
SIOCSIFADDR: Invalid argument                                             [ ok ] 
 *     eth1:1... 
 
So even without net.eth0 the problem is still there. 

[Comment 9 Martin Schlemmer (RETIRED) 2003-03-30 14:58:48 UTC]

Ok, please attach net.eth1.

Patch for net.eth1

It seems this patch fixes the bug. It uses perl instead of awk.

net.eth1

Here is net.eth1

[Comment 12 Martin Holzer (RETIRED) 2003-10-17 11:19:20 UTC]

is this still an issue ?

[Comment 13 Heinrich Wendel (RETIRED) 2003-11-19 06:30:43 UTC]

please reopen with answer.
