Hello.



I’m trying to check the uptime of a Cisco 2960X switch on Nagios with
check_snmp plugin but I always get the following error:



[root at nagios]# /usr/lib64/nagios/plugins/check_snmp -P 3 -U snmpv3user -L
authPriv -a MD5 -A v3p4ssword#1 -x DES -X v3p4ssword#2 -H 192.168.254.2 -o
DISMAN-EVENT-MIB::sysUpTimeInstance

External command error: snmpget: Authentication failure (incorrect password,
community or key)



I get the same error on the web console:




My switches.conf is like this:

This happens because the shell translates the hash in your password to
the end of the command and the start of a comment. You need to use
either single or double quotes around both your passwords in order for
the shell to see them as a single argument.
check_command           check_snmp!-P 3 -U snmpv3user -L authPriv -a MD5 -A
v3p4ssword#1 -x DES -X v3p4ssword#2 -o DISMAN-EVENT-MIB::sysUpTimeInstance

So type in v3p4ssword#1 as 'v3p4ssword#1' with the quotes, and do the
same for 'v3p4ssword#2' and it should work.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
