Question Ubuntu 10.04.2: dhclient and NetworkManager problem: eth0 connection lost


Hi,

I'm running Ubuntu 10.04.2 LTS and from time to time eth0 connection is lost. Looking at syslog (below), can anyone tell if its a hardware (network card) problem or a software bug?

Thanks,

Leandro


syslog file:

Is eth0 a wireless interface or a wired one?

It's a wired one. Below is another log. As you can see, the first "block" (10:47:07 to 11:12:07) shows something that I can't understand (the error). The second block (13:50:50) shows the correct behavior. Some times DHCPACK and bound msgs never occur and then eth0 connection is lost.

It seems that the DHCP packet is not reaching the server. You can try with a static address and then ping the server for a while to see if there is a connection problem.

SOLVED!

The problem is with on-board netword card. The LAN speed was updated to 1 Gbit. Putting another card solved the problem.
