I have a Linux server where I have 2 eth cards.
I use it to forward packets from my network to outside, and I wanted to monitor the traffic usage of each machine, so I created multiple eths... last Friday I got it working, I configured snmp and mrtg, and it was monitoring fine (for example) the eth1:1 (10.3.0.1/30)... but it stopped to monitor some time after that!
I checked all the configuration files, it's everything like at the beginning, and it's not working anymore!
I thing it's something with the routing table, but, it's the same!
Any help will be very appreciated!

Anyone?

Any error message?
Cron deamon running?
What you get if you run MRTG in manually.
Post specific error on here.

Good Luck,

Thanks for your reply!

Thats the weird thing... i got no errors!
Simply it doesn't monitor the virtual interfeces... it only worked the firts ours I installed everything.
