I'm working on a subagent snmp application here, and found that the standard
build of
net-snmp's snmpd (not the mini-snmpd) doesn't include agentx support at all,
nor TCP.
I'd really like to see this enabled across the board, if I wanted to have a
really small
snmpd, I could use mini-snmpd, but if I've chosen the full net-snmp package,
I'd like to
have it mostly functional :)
Of course, this does make it marginally bigger, but is that really a problem?
Also, should the agentx support be enabled by default or not?
Cheers,
Karl Palsson

Subject: [PATCH] net-snmp: Include support for agentx
agentx is the recommended method for operating sub-agents, but was not
enabled in the default build. agentx also requires TCP support to be
enabled.
Included updates to the init script to handle agentx config and turned
it on by default.
Included the snmptable utility as well.
