hi amos,

i'm out of ideas on why your Target line doesn't work :(

MRTG has a templating facility ... i haven't used it, however, so i 
don't have any brilliant insights to offer

i, too, became tired of cutting & pasting all those lines into my config 
files ... so i wrote code to do it for me (see 
http://www.skendric.com/trend/graphs/mrtg-net-snmpd.pdf for the 
results).  i add hostnames to a text file now, and every night, a cron 
job reads that file, rebuilds the relevant mrtg config file, and life is 
sweet.  the code is available off SourceForge (the 'Netops toolkit') or 
directly from http://www.skendric.com/device/

since i haven't used MRTG's template facility ... i don't know what 
would be easier ... to figure out MRTG templates or to wrestle with my code
