Note: The correct port to use depends on whether you are using the original NSClient (port 1248) or NSClient++ (port 12489)

Passwords

If you are using passwords with NSClient, there are two places you will need to configure them.

For data collection, you'll need to edit nsclient-config.xml. This follows the same structure as snmp-config.xml.

For polling, you'll have to add a parameter key of "password" and a value of the plain text password being used. If you have multiple passwords for different devices you'll need to set up separate packages with the password key changed in each one.
