Subject: [gentoo-user] dhcpcd won't run at certain network points
Date: Wed, 14 Mar 2007 15:09:41
1 Hi all,
3 Why am I always the one to get the wierd hardware issues? Here's my
4 latest. The powers that be at work made me move my desk, and dhcpcd on
5 *this* laptop doesn't work at *this* network point, or any of the other
6 four in this row of desks, althought hey work OK on Windows. It's most
7 certainly a cabling issue, I can go to the server room and plug a
8 flylead into the *same*port* on the switch and it all works right. A
9 static ip isn't an easy option as I move between different networks and
10 don't want to have to keep editing resolv.conf. I'm not allowed to do
11 my first reaction, which is to swap my outlet with a working one...
13 tcpdump shows me this when I insert the network cable:
14 16:11:06.855229 IP > BOOTP/DHCP,
15 Request [|bootp]
16 repeated 6 more times then it times out
18 With a static ip, I do get full bandwidth, error free, just like it
19 should be. So whatever this cabling issue is, it affects only bootp...
21 hardware: Dell Latitude D810:
22 NIC: 02:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5751
23 Gigabit Ethernet PCI Express (rev 01)
24 kernel module: tg3
25 kernel version: 2.6.20-gentoo[-r1]
26 /etc/conf.d/net: empty (i.e. default)
28 I would use google, if only I could think of a remotely meaningful
29 search string :-) The hdcpcd docs and kernel module docs are not very
30 enlightening. And the DHCP server is a Windows domain controller.
32 Anyone know of a dhcpcd or tg3 module option that will provoke this
33 network to give me what it should?
