Nagios Support Forum

Thanks.

Regarding net-snmp-config --create-snmpv3-user -a password testuser, you can ignore that as it turned out my CentOS version does not support that, but does support /usr/bin/net-snmp-create-v3-user -a password testuser.

Don't know why am getting the unknown username error.


Kind regards

Thanks Yancy, I have tested against check_snmp from the command line as advised.

Thanks Yancy, I get your point. On the device I am monitoring, I have the following snmp command, "snmp-server host 1.1.1.1 version 3 auth <snmp username>" . Where 1.1.1.1 represents the snmp host. In which command line argument do I need to configure the snmp V3 I have created? What comma...
