Occasional Network/DHCP weirdness
Hi all,
I've got a network server set up that runs a basic installation of Debian
Potato - no X, etc. Because our ISP uses DHCP that's what the server set to
use, and most of the time it works just fine (It's set up with dhcp-client).
But every now and then it loses the connection altogether. At first I thought
this was due to the unreliability of the ISP, and this was the reason on some
occasions. But not all the time ... if I was having a problem I would usually
run '/etc/init.d/networking restart' and it would reconfigure the network and
most of the time that would be enough, but not always. Sometimes it would
claim to find the ISP's gateway, would bind itself to some IP address and
display the number of seconds till the next lease. Yet pinging a known IP
address (eg the university's) would either not go through or even more
shockingly return with the response 'operation not permitted'. There was a
Windows-like solution to all this though - shutdown, reboot and re-run
'/etc/init.d/networking restart'.
This problem seems to have something to do with leases, but also with the ISP
going down and the network not coming back up when the ISP is back up. This
is a mystery I'd very much like solved if possible.
