netcfg rc3 - dhcp failing
Hi
I've trawled the debian-boot mailing lists regarding the netcfg tool in
the netboot debian install and I was unable to find any existing
instances of this problem, so I was wondering if you could help.
The problem:
We are finding that during a network installation of debian, using the
d-i 2.6 kernel and initrd.gz, the install will stop at the dhcp/netcfg
step:
──────────────────┤ [!!] Configure the network ├────────────────────┐
Network autoconfiguration failed
Your network is probably not using the DHCP protocol. Alternatively,
the DHCP server may be slow or some network hardware is not working
properly.
<Continue>
If the user at this point manually selects 'continue' and then selects
'Retry network autoconfiguration' then the d-i successfully completes
dhcp autoconfiguration and continues into the installation.
However, if one jumps into the second virtual terminal after the above
netcfg failure and checks the interfaces and the routing table, you see
the following:
~ # ifconfig -a

So it seems that the netcfg succeeds to obtain the dhcp address but does
not seem to realise it. This is on hardware requiring the e1000 or tg3
driver using the 2.6 kernel. However, when booting on systems which
require the e100 driver we do not see this problem.
Can you offer any advice as to why this might be happening? Do you
think it could be related to the isc-dhcp server which I'm running? Or
to the e1000/tg3 drivers?
Please let me know what further information would be of use to
diagnosing this problem.
Many thanks. Kind regards
