What about:

1) copy the mrtg.cfg file to another file
2) run that file through sed, changing "1:public at host" into
   the oid you're interested in, and changing the target name
   into something else
3) append the outcome of (2) to your mrtg.cfg file

For instance:

   cp mrtg.cfg mrtg.copy
   sed 's/: \([0-9][0-9]*\):/: ifInOctets.\1\&ifOutOctets.\1:/
        s/\[\(.*\)\]/[\1_changed]/' < mrtg.copy >> mrtg.cfg

Of course you change ifInOctets and ifOutOctets in something else
and you check and double check before you take that into production.
I haven't tested it myself however it seems to produce valid results.

The sed program (Streaming EDitor) is also available for WinNT in
case you use that os!
