Yes I agree with that but I know most services by head and 'service'
gives you some safety against accidental mistakes.
The results of iwconfig:
o no wireless extensions.
eth1 no wireless extensions.
wmaster0 no wireless extensions.
eth0 IEEE 802.11bg ESSID:"nwhq_wireless"

pan0 no wireless extensions.
This looks normal except there is no IP-address for eth1 as my dhcp
server apparently refused it. The interesting fact is that in this case
wireless was the only network connection.

Where wmaster0 and pan0 reside I don't know. That eth1 had no IP-address
is correct: it is not connected.
The wired connection works OK.
The MAC-address 00:C0:49:54:77:9E is the address of the wireless router.
When I do a "networking restart" it gets it's wired address from the
dhcp-server but the wireless sends DHCPDISCOVER packets to the same
server on the net but the dhcp-server doesn't respond. This is the same
with or without the wired connection. Maybe I have to look at the
response packets from the dhcp-server?
It is still a mystery where the problem is.
Hope you have still some suggestions.

P.S. I'm resending this message as for some reason it didn't reach the
list (at least I didn't receive it).
