This on both Centos 5.9 and Centos 6.x machines.

All have problems with network devices now. However I'm not 100% sure if this was caused by this update or maybe some other, just disovered it. Wasn't like this like week though.

The Centos 5.9 server has lost his second ip (I don't use manually made ifcfg-eth0:0 files for it. When restarting network, this error occurs:

Bringing up interface eth0: iwconfig: error while loading shared libraries: libiw.so.28: cannot open shared object file: No such file or directory

The eth0 interface does start, but eth0:0 which is created automatically by DA is not coming up again, neither when restarting DA.
The second ip is present in /usr/local/directadmin/data/admin/ips.

On the Centos 6.x servers, same problem, after restarting network, but another error occurs:

Bringing up interface eth0: RTNETLINK answers: Permission denied

In this case eth0 comes up also, but eth0:0 (the second ip in DA) is gone and won't come back.

Note: We did -not- change anything on ip configuration.

Anybody a clue on what's going wrong and how to fix this so erros are gone and second ip's are working again?

Fixed the error on the Centos 5.9 server by installing wireless-tools. I even wonder why that is needed because there is nothing wireless. However, the second ip still won't show.

Got the second ip's backup now by restarting startips.

So everythings fine again except for this error:

Bringing up interface eth0: RTNETLINK answers: Permission denied
