RV: check_snmp : External command error with no output (return code: 3)

[Ricardo Melendez]

Hi, this is the verbose output,

 

nagios at nagios:/usr/local/nagios/libexec$ ./check_snmp -H 192.168.1.5 -C
MYCOMMUNITY -o ifOperStatus.1 -r 1 -m RFC1213-MIB -v

 

/usr/local/bin/ -t 1 -r 5 -m RFC1213-MIB -v 1 [authpriv] 192.168.1.5:161
ifOperStatus.1

External command error with no output (return code: 3)

 

It seems that the "/usr/local/bin" directory is where "snmp-net" package is
installed, all the binaries are here.

 

Any idea.

 

Thanks

Asunto: check_snmp : External command error with no output (return code: 3) 

 

Hi to all, it is my first submission to the list, I have installed a Nagios
server based on the Core Documentation (Quick Start Guide and related), I am
trying to monitor a Linksys router via SNMP, but not successful yet.

 

The command:              

 

snmpwalk -v1 -c MYCOMMUNITY 192.168.1.5 -m ALL .1

 

Returns all the snmp objects available in the router

 

But, the command:

 

./check_snmp -H 192.168.1.5 -C MYCOMMUNITY -o ifOperStatus.1 -r 1 -m
RFC1213-MIB

 

Returns "External command error with no output (return code: 3)",  for any
MIB Object, and the nagios web interface shows the same, the set up is based
on the example file included "switch.cfg".

 

 

Any suggestion to fix that.

 

Thanks in advance.
