I have a script that uses CUPS lpstat -h command. However, the remote server I am trying to get a response from asks for a password. But I need to execute this script from within Nagios, so I have two questions I am hoping someone can shed some light on.

First, does anyone know of a way to include the password when sending the lpstat command? Example would be: lpstat -h -p PO1 the address is my remote server, PO1 is the name of the printer on that server. It seems cups left out a way to add a password to that command, so it comes up as a prompt.

Second, if I have a script that uses that lpstat command integrally, is there a way to execute the script AND send the password from one command? I tried to echo it but the prompt doesn't accept that. I don't see a prompt when executing the script, it just hangs until I enter my password and press enter, then it completes and outputs the result I need.

I tried using expect scripts, but since there is nothing to expect (if running the script that uses lpstat, I don't get an actual prompt), so I just sent "send" commands, which seems to execute the script but didn't pass on the output.

I'm stuck here, all the scripts I have found for remotely checking the status of a CUPS printer require user input, and unless I can find a way to do it in one line and output a result, I can't use it in Nagios.

    Instead of executing lpstat locally pointed at the remote host, you could use nrpe to run it on the cups server which will not require a password if the user is in the lp group.

  • Hmm, I think that might work. I modified the script to remove the -h and tested it on the server and it ran just fine, so I will add it to my nrpe config, enable the arguments through nrpe, and set it up on the nagios server and see if it returns the right info. Thanks!

Although I didn't find the answer to the title, jordanm's response led me in the direction I needed. I was able to use nrpe to execute the script on the print server and therefore didn't need to enter a password.
