Network connections drop after login

TheStarLion · 01-28-2010, 09:04 AM

Fresh install of Mandriva, all packages updated to their states as of 2pm GMT. Just in case it helps.

I've got a direct wired connection on eth0 to the network's router. On login, one of two situations happen, apparantly randomly decided.

In one case, it reports the network connection as up, then after a few minutes, it still reports as up, but all network and internet apps (EG dropbox, firefox) insist the network connection is down. Attemtping to disable and re-enable the connection causes system lockup.

In the second case, it reports the network connection is down. It can be manually raised, but after that, it's exactly the same as the first case.

In addition, it seems to have trouble deciding which is eth0 and which is eth1, as a few times, it connects to the router using eth1 instead of eth0, yet the only network cable connected goes to what has always previously been eth0. This may or may not be related.

You are talking about Mandriva 2010 right?
I've not seen this problem before. But I'd suggest first turning off IPv6 to see if that helps. You can do this from Network Center > Advanced Options. A reboot is required to take effect.

Thanks, that seems to have worked - so far.
But, I still have to bring eth1 up manually on login, and multiple people use this computer - I'm the only one with the root password to allow for it to be brought up, since the setting 'allow users to manage this connection' always becomes unchecked, no matter how many times I check it.

TheStarLion · 01-30-2010, 09:08 AM

Update:
It still drops after several minutes.
It doesn't lock up when manually trying to re-establish a connection, but it still can't actually re-connect.

The eth0 & eth1 you mentioned, they are both wired Ethernet cards?
Could be something to do with the module you're using.
Can you post the output of lspci -v, ifconfig -a & lsmod.

Also you can use a udev rule to fix the eth names so that they stay consistent.
for Mandriva, it can be done inside this file /etc/udev/rules.d/70-persistent-net.rules

TheStarLion · 01-31-2010, 02:09 PM

They both are wired ethernet, yes. For the moment, they appear to have stopped switching around.

I retrieved these outputs of the three commands, run as root, on the Mandriva box:
