No - that's wrong.
The -x option is used to specify an *AgentX* socket.
So the agent is now listening for AgentX connections
on the standard SNMP port, and listening for SNMP
connections on the named socket /tmp/snmp.skt
This won't work.

That's because it's a UDP-based server, not TCP.
Though you've started it in a very strange manner (see above)

Try the following:
- Shut down the agent
- Run "netstat -ultmp"
Is there *anything* listed with port "161" ?
If so, then stop.
- Run "snmpd -f -Lo -c /path/to/your/snmpd.conf"
That worked . It is responding to the SNMP commands . Thanks a Lot.
regards...

I was mislead by this display when I ran snmpd also, since the UDP
protocol
is used, a LISTEN state is not displayed.
It looks like your snmpd is running
Good luck.

Subject: Re: configuring net-snmp from source
so you can do 1 of 2 things (choose one)
a) run snmpd like this: # ./snmpd -f -Lo -c /path/to/your/snmpd.conf
I tried that but it gives me the same error. Then I tried
with
./snmpd -f -Lo -x udp:127.0.0.1:161
<http://127.0.0.1:161/> /tmp/snmp.skt
Then there is no error and it displays the message
NET-SNMP 5.4
But there is no SNMP agent listening after I checked it
with
netstat -ultnp
The following is the output as displayed by netstat
-ultnp

As you can see from the last line , snmpd is not in listening mode.
Please somebody help me in starting the agent so that it responds to the
snmp commands.

May be this is related to the config file...

read this manual: man snmpd....
at the end you will find:
----------------------------------------------------------------------------
CONFIGURATION FILES
snmpd checks for the existence of and parses the following files:
/etc/snmp/snmp.conf
Common configuration for the agent and applications. See
snmp.conf(5) for details.
/etc/snmp/snmpd.conf
/etc/snmp/snmpd.local.conf
Agent-specific configuration. See snmpd.conf(5) for
details. These files are optional and may be used to configure access
control, trap generation, subagent protocols and much else
besides.
In addition to these two configuration files
in /etc/snmp, the agent will read any files with the names snmpd.conf
and
snmpd.local.conf in a colon separated path specified in the
SNMPCONFPATH environment variable.
/usr/share/snmp/mibs/
The agent will also load all files in this directory as
MIBs. It will not, however, load any file that begins with a '.'
or descend into subdirectories.
---------------------------------------------------------
so you can do 1 of 2 things (choose one)
a) run snmpd like this: # ./snmpd -f -Lo -c /path/to/your/snmpd.conf
I tried that but it gives me the same error. Then I tried
with
./snmpd -f -Lo -x udp:127.0.0.1:161
<http://127.0.0.1:161> /tmp/snmp.skt
Then there is no error and it displays the message
NET-SNMP 5.4
But there is no SNMP agent listening after I checked it
with
netstat -ultnp
The following is the output as displayed by netstat
-ultnp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address

Please somebody help me in starting the agent so that it responds to the
snmp commands.
With Thanks and Regards
b) try completing the instalation with # make install... I guess this
will copy the config files to /etc/snmp/ and the agent will
automatically find thgem there (# ./snmpd -f -Lo)
hope this helps.
