Hi Pushpa,

You are not enabling UNIX domain support, so net-snmp can't open the UNIX
domain socket for agentx. You can either use the TCP socket by configuring
with something like

agentXSocket tcp:127.0.0.1:705

and then configuring clients similarly, e.g., "snmptrap -X tcp:705"

Or adding the UNIX domain transport, e.g., add "Unix" to your
"--with-transports" configure argument.

  Bill
