[mrtg] MRTG - Specify interfaces

[Jan Ferré]

Ehhh - you're to set up a cfg-file with content something like

WorkDir:  xxxx
Refresh:  300
Interval: 5
LogFormat: rrdtool
Target[PHK.LY8-DASV.IN-OUT]:
ifInOctets.14&ifOutOctets.14:xtremelysecret at 130.225.244.221

aren't you?

The .14 is the ifindex for the desired interface. Which can be found
using a smtpwalk on the equipment.
And if you desire more interfaces, just add more target lines

Best regards

Jan Ferré
