Description Simon Goodall 2006-11-21 04:41:05 EST
Description of problem:
Since upgrading to FC6, NM has had problems connecting to the wired network on
my machine. It hangs waiting for an IP address (normally obtained when the NM
service starts). If I then click on a wireless network option it then gets an
address and tells me its connected to the wired network. The list of networks
then show *both* the wired and wireless network as selected. The connection
information shows throughout.
In this state some network services work e.g. web access but printing does not.
The is probably due to our wireless network being more restricted than the wired

I have to disable wireless and restart NM and I think re-modprobed my wired
driver to get it working again.

I have a dell inspiron 8500. My wired card used the b44 driver and my wireless
card uses the ipw2200 driver.

In FC5 NM would have already connected to the wired network by the time I logged in.

Version-Release number of selected component (if applicable):

How reproducible:
Often (always? -- most network activities are still working so not always
accessing the ones that don't)

Steps to Reproduce:
1. See description
Actual results:

Expected results:

A-ha! I see the same problem, but the the 8139too driver module. It seems a bit
intermittent, tends to happen more with my place-of-work network. For
comparison, I've a notebook I keep at home that has the RTL-8139 and disabled
Broadcom 4306 chipsets, but this one has not problems connecting to the home
wired network.

I've attached the relevant log extracts. Curiously, you'll note that line 197
states "DHCPRELEASE on eth1 to port 67". eth1 is my ipw2200
wireless, and is the address of my home DHCP server. However, this
machine was started from cold in the office today.

Comment 3 James Ettle 2006-11-29 07:29:53 EST
Actually, looking at the following lines in that log extract...

Nov 27 11:47:59 harmony NetworkManager: <information>	Activation
(__tmp1804289383) Stage 3 of 5 (IP Configure Start) complete. 
Nov 27 11:47:59 harmony NetworkManager: <information>	DHCP daemon state is now 1
(starting) for interface __tmp1804289383 
Nov 27 11:47:59 harmony dhclient: Bind socket to interface: No such device
Nov 27 11:47:59 harmony dhclient: exiting.
Nov 27 11:47:59 harmony dhcdbd: Unrequested down ?:3

I think __tmp1804289383 is what udev called the 8139too device before it's
brought up by NetworkManager. When 8139too is reloaded, it's named eth0 and then
the DHCP client works OK. This could be a udev problem...
Comment 4 James Ettle 2006-12-04 12:24:27 EST
As a work-around, I've created the file /etc/udev/rules.d/010-netnames.rules
(found on some web-site somewhere) with the content

KERNEL=="eth*", SYSFS{address}=="<wired-mac-address>", NAME=eth0
KERNEL=="eth*", SYSFS{address}=="<wireless-mac-address>", NAME=eth1

which seems to have improved things for me...

Comment 6 James Ettle 2006-12-12 06:19:25 EST
I spoke too soon... didn't really work. Adding an /etc/iftab and moving
010-netnames.rules to 61-netnames.rules worked for about a week, then it broke
again. Looks like dhclient is having trouble with the long __tmp name.
