Re: Failed to connect to the agentx master agent

Hello,

Try starting the master agent using
    snmpd -f -Le    (plus any other options that are typically supplied)
Is anything logged?

This is what I get after I run the command.

Duplicate IPv4 address detected, some interfaces may not be visible in IP-MIB
could not open /proc/net/if_inet6
Turning on AgentX master support.
NET-SNMP version 5.3.0.1
cannot open /proc/net/snmp6 ...


Which ports is the master agent listening on?
Compare the list of ports for the 5.3.0.1 agent,
with the list of ports for the other agents.

Normally, you'd expect the agent to be listening on
TCP port 705 and/or the named socket '/var/agentx/master'


This is what I get when I run netstat -a | more

Thanks & regards,
Nop.

Well, the first thing to check is whether the master agent is actually
listening for AgentX requests.

Try starting the master agent using
    snmpd -f -Le    (plus any other options that are typically supplied)

Do you see either of these?
