This is somewhat strange, after an average of 25 days of uptime, either with kernel 2.6.6 or kernel 2.6.7 (didn't notice this with earlier kernels, but the problem may be there as well, sorry but I didn't care about this before, and the box is in production so it cannot be rebooted easily), ifconfig does not display the inet6 addresses of my interfaces anymore, but the addresses work as expected and are correctly in iproute output:
golem:/etc/shorewall# ifconfig eth0 eth0 Link encap:Ethernet HWaddr 00:50:FC:5A:0B:58 inet addr:192.168.203.1 Bcast:192.168.203.127 Mask:255.255.255.128 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:50564399 errors:0 dropped:0 overruns:0 frame:0 TX packets:46289378 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:3363466008 (3.1 GiB) TX bytes:1097487814 (1.0 GiB) Interrupt:10

oh, as you can see I just now noticed that ifconfig dropped the secondary interface IP address as well..
This is a vanilla 2.6.7:
Linux golem.softmedia.lan 2.6.7 #1 Fri Jul 2 11:11:30 CEST 2004 i686 unknown 15:41:42 up 27 days, 4:21, 2 users, load average: 0.01, 0.00, 0.00
..running a debian woody:
net-tools 1.60 ifconfig 1.42 (2001-04-13)
Known kernel bug, ifconfig bug, whatever? A net-tools upgrade from backports.org is possible, what do you guys think about this issue?
