there is a problem with dhclient:

-----------------------------------------------------------------------

---------------------------------------------------------------------------------------------

I have wrapped the /sbin/dhclient to see, how is it called.

The problem is with "-4" parameter, which dhclient3 in Ubuntu 9.10 don't know.

So i wrote this workaround:
---------------------------------- /sbin/dhclient
#!/bin/bash

logger "xxxxx $0 $*"
logger "Odstranuji neznamy parametr \"-4\""

PARM=$(echo $*|sed "s/-4//")
exec /sbin/dhclient3 $PARM
---------------------------------

Now it works again:
