SNMP resources
A good place to go for free SNMP software is netsnmp.org,
or maybe now it's net-snmp.org,
home of ucd-snmpd. The learning curve is steep, but the software does the job, and covers
both client and server side.
fsubagent
In January 2001, while working at Disappearing Inc. (now Omniva Policy Systems),
I needed to make some minor updates to the SNMP agent in our server. One thing
led to another, and soon I found I'd come up with a little helper library for
ucd-snmpd that might save other people some time. When I left Omniva in July 2001, they kindly
gave permission to open-source the library. I polished it up, named it 'fsubagent',
and published it here. Enjoy.
