Thumbs up Ubuntu logs


Hi Team,

My remote Ubuntu 11.04 machine has network issue where i cant connect to it. To track the issue, i want to enable the network error logs. Does anybody have an idea about it ??

Thanks guys,
Cheers!!

there is no such thing as a "network error log". what do you hope to see?

not a networking question, moved to Linux - Newbie.

sure, but what would be in them? There are so many ways you can look at a network, it doesn't make sense to "log" it. How about you back up and explain what problem you're having.

i have this virtual machine. i connect to it via ssh. suddenly the connection goes off-line and i cant reconnect for sometime but the machine is not shut-down. it comes back online when we restart it manually. so i thought the issue cant be tracked through logs..

Well at the hardware level you might see something in dmesg or usualy log files in /var/log/messages, but you won't find logs for the "network". If the sshd process screws up, note that that's not networking, that's a program that happens to use the network.

Oh right, sorry I get you now. well the nic may be going up and down if it's everything. Can you ping it at all? if it is going up and down /var/log/messages may well reference eth0 bouncing.
