[SNMP4J] is there something special about a SET command?

[Noel Grandin]

Hi

Thank you very much!
A days worth of debugging fixed in 5 minutes!

Is there some kind of SNMP programming tutorial on the web?

Perhaps a link to it in the documentation might be useful for newbies like myself.
I have the RFCs, but wading through 21 different documents is a tough job :-)

Regards,
    Noel
