Re : verify connection to master agent

<!-- DIV {margin:0px} --Hi,

thanks for your reply. I looked at the snmpd.conf man page. 
As a result I added 
netsnmp_ds_set_int(NETSNMP_DS_APPLICATION_ID,
                NETSNMP_DS_AGENT_AGENTX_PING_INTERVAL,10);

in the initialization of my subagent. 

then I tried to stop my master (snmpd) and start it again. Then my subagent is not able to register again. I got the following error:

Error: Failed to connect to the agentx master agent: Unknown host (No such file or directory)

AgentX master agent failed to respond to ping.  Attempting to re-register.

Any ideas??

Please see the snmpd.conf(5) man page - in particular
the 'agentPingInterval' directive.

Have a look at how  this directive is implemented - in particular,
follow the code through from 'agentx_reopen_session()' (in the file
mibgroup/agentx/subagent.c)
