Matt,
I tried some higher port to open TCP socket for agentX but didn't solve
the problem. I would like to get some information from Net-SNMP folks,
whether or not TCP/UDP agentXSocket is really blocked on Sun Solaris-10.
Regards
Birendra

Birendra,
I am not sure about Solaris, but there could be a problem running on
privileged ports. You might try running your agent on a higher port
number and see if that works.

Larry,
I think problem here is something different. Please see the details
below:
Solaris 10 is shipped with System Management Agent(SMA) which is an SNMP
agent that is based on Net SNMP. The Net-SNMP version used in SMA is
5.0.9. We are using iReasoning Agent Builder for subagent building.
These are Java based agentX subagents and requires a TCP port on which
the master agent is listening to establish a connection. I tried to
enable TCP AgentX connection on port 705 by adding the following two
lines in the /etc/sma/snmp/snmpd.conf file,
master agentx
agentxSocket tcp:localhost:705
But this doesnot help. The same thing worked on Linux. Even netstat -an
doesnot show the agent listening on 705 tcp port and my subagent fails
to connect to the Net Snmp master agent.
The snmp log shows the following error,
bash-3.00# tail -f /var/log/snmpd.log
seaproxy_sendReq: SEA Master Agent not responding
Turning on AgentX master support.
Error: tcp:localhost:705 transport is not supported, disabling
agentx/master.
NET-SNMP version 5.0.9
In SMA, the only allowable AgentX transport is UNIX domain sockets, so
only sessions on UNIX domain sockets are created. It does not allow
subagents to use UDP and TCP ports, refer
http://docs.sun.com/app/docs/doc/817-3155/6mip4hnn0?a=view. As Java is
platform independent and UNIX domain sockets are unix specific, Java
doesnot support Unix domain sockets.
Regards
Birendra

Hi,
Check my long thread circa April 18, labeled "5.4.1 won't talk". Recent
versions turned out to have a requirement that older (5.2.1) versions
did not, to make certain setup calls in a certain order or otherwise the
socket connection does not get made. I don't know if this is related to
your problem but it could be.

How can I enable the TCP AgentX connector?

The net-snmp AgentX implementation supports TCP
connections.
See the snmpd.conf manpage for details. Note that the TCP
AgentX
connector is known to be insecure, which is why the agent is
usually
shipped with it turned off.
