RE: snmptrapd - decoding OIDs not working

Thanks for your help

I understood that all daemons and utilities used the snmp.conf configuration file and this is what puzzled me.

I have just realised that the -C parameter suppressed reading the standard files! That was causing my problem! I had not revisited my command line options.

c:\usr\bin\snmptrapd -c c:\usr\temp\snmptrapd.conf  -Lo

This works as expected!

Your suggestions also worked but I am aiming for very simple command lines with all the basic configuration held in configuration files. At least it showed me that the principle worked and I now have a solution I can move towards my production environment.

You must tell snmptrapd where the mibs are with -m just like you would
snmpd.  All of the options for start/stop apply to all of the
daemons/utilities.
