Network will not start while trying to use network manager?

Hi All,
Hoping for some help in troubleshooting.

I ran the latest update, and have had nothing but issues with the network. I have a broadcom card in my notebook, and went so far as to reinstall from repos and to build it from the broadcom sources.

The crux seems to be that I cannot get the network service to start up if the system is configured to use networkmanager.
Trying to manually start the network via yast, I get:
/etc/init.d/network start returned nil (unspecified error)

Runnig from the command line gives me
Starting the Network Manager… done
Connecting…

Then after 30sec it tells me it’s still waiting
When I go to look, network never starts.

Now, if I switch it to using ifup/down, the network starts up, and everything connects (although to be fair, I have issues with the wireless getting the right DNS, but that’s prob not important right now), which tells me that the drives are correct, it’s something in network manager.

I’m on 11.3, Kernel 2.6.34.7-0.5-default.

Anyone have any insight? Where the heck are the devug logs for the network startup so I can get more information?

Thanks!

Try /var/log/NetworkManager. I would like you to try the stuff in

to see if that helps.

Thanks.
I cannot get anywhere with the writeup you did. As mentioned, the network will not come up at all when selecting network manager under YAST->Network.

I consistantly get Error - no network running.

I took a look in the log file, and there is nothing there prior to sept 4th. (although the file time is current…)

I get one of those, then the network comes up.

What do you see when you enter the commands below?


ps ax | grep etwork
sudo /usr/sbin/NetworkManager
knetworkmanager

As you did not tell us which desktop you are running, I have assumed KDE.

Yes - it’s KDE 4.5.3-9.2, networkmanager 0.8.2-78.1, and NetworkManager-KDE4 0.9.svn1192577-7.2

Thanks again! It’s driving me nuts :slight_smile:

Your system has something corrupted. I would try an update using either the 11.3
DVD or the 11.3 NET install CD. WHen you configure wireless the next time, tell
the system to use the wallet and create it with no password. It hurts security,
but not as much as disabling the wallet.

OK - what do you mean by that? Are you saying to remove all repositories except the official 11.3 repos and then do a complete update/reinstall of all older packages, or just the network related ones?

Hmmmm…
Sounds to me like Network Manager is running, but it’s having a problem connecting.
Trying IFUP/IFDOWN is one step, it indicates that your network is running.

If Network Manager is running but not connecting, have you manually added and configured your Wired Network to Network Manager or did you think it was going to be done automatically on its own?

Tony,
Yes and no (I think). Network Manager tries to come up, but once it cannot connect to the network services, it dies… well, it actually never starts.

When I swap to using IFUP/DOWN in YaST, the network services come up fine, and it’s able to connect.

The more I look at this, the more I am convinced it’s an issue with something they just did in gnome renaming packages which I vaguely noticed during the last update. I wish I could find some debug logs to look at while the network script tries to come up, but so far no dice.

No. Start with the DVD or NET install CD and start an installation. At one
point, it will offer you the option of doing an update. Note, the Live CD WILL
NOT WORK.

Ah Ha!
So I’ve managed to find the issue. There is a known bug with the Broadcom tg3 wired ethernet driver and networkmanager crashing.

Once I removed the module from loading by blacklisting it in the kernel, networkmanager starts up. It’s worth noting that using YaST->Network-> use network manager still gives the error “No Network Running”, but it does come up.
