[mrtg] MRTG showing incoming data during time when PC is shut off

[Rohit V Bhute]

My setup is as follows
[PC1]<eth0>----------<ADSL modem DLink GLB-502T>
[PC1]<eth1>----------<sometimes connected to PC2 through crossover>

I have setup MRTG to log both eth0 and eth1. I have uploaded the graphs 
here.
Log yesterday night - <http://rvbhute.org/eth0-day1.png>
Today morning, when I switched on the PC. - 
<http://rvbhute.org/eth0-day2.png>

I did some note-taking. The speed it is showing is 1306KB/s - it is the 
last recorded current speed before I switched off the PC.

Incidentally, another problem is today morning when I switched on the 
machine, by default, eth1 was selected by the Ubuntu Network manager. 
Though I selected eth0 to get on to the net, MRTG has logged all traffic 
to eth1. - <http://rvbhute.org/eth1-day2.png>

Do I have to bind the interfaces to their MAC or something?

My /etc/mrtg.cfg is below:
# Created by
# /usr/bin/cfgmaker public at localhost


### Global Config Options

#  for Debian
WorkDir: /var/www/mrtg

### Global Defaults

#  to get bits instead of bytes and graphs growing to the right
Options[_]: growright
WriteExpires: Yes
EnableIPv6: no
