Hi there,
I have a Xircom Realport NIC in my notebook which run Debian Woody stable
and now unstable.
I have to use a dhcp server (dhcp-client 2.0pl5-15) when I am connected in
the office and no network connection while I am at home.
The problem now is, that while I am at the office and dhcp is working
everything is fine and I can shutdown/reboot the machine and it always
comes up again with a fresh dhcp connect.
Now when I am using the computer at home for a while (without network link)
and come back into the office, the network link does not come up again.
ifconfig shows the eth0 interface but the ip address is missing. Everything
else seems to be ok. Of course there is no routing information because dhcp
gives up after a while with the following messages:
... dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 7
<repeated>
... dhclient: No DHCPOFFERS received.
... dhclient: No working leases in persistent database.
... dhclient: Sleeping.
On the dhcp server I can see that it actually does get a connection
assigned but somehow the communication on my clients side looses something.
I also tried the dhcp3-client but it didn't make any changes. After I run
the notebook without network link something seems to get messed up.
To get it back to live, I have to start/stop /etc/init.d/networking,
/etc/init.d/pcmcia and /etc/pcmcia/network a couple of times. So far I was
not able to find a procedure which always works to get the link working
again.
Just kill -9 dhclient, take out the card and put it back in.
Or try the following:
killall dhclient
/sbin/dhclient eth0
The latter works for me to "update" the dhcp lease on my laptop after a
lengthy suspend.
