Nagios 3 and SSH

[Metalliogre]

I am getting a 'connection refused' on my SSH in Nagios. I couldn't find squat on how to configure. Any advice would be helpful. Thanks! Screenshot is attached.

Do you have an ssh daemon running on the local nagios server? Is port 22 open?

[Metalliogre]

No sir. I am not aware on how to take these steps. Any helpful info would be greatly appreciated.

Depending on your server's OS, you might have to install SSH in a different way. It looks like you are running Debian, so this should work:

Code: Select all

sudo apt-get install openssh

Thank you! I will try as soon as possible. How do I go about opening port 22? Thanks!

Tried that command and got a 'cannot find openssh package' error.

Try:

Code: Select all

apt-get install openssh-server

Did this and it solved my SSH problem! Thanks! Here is a nice guide on how to configure SSH-Server.

It started refusing my SSH connection again

It's been a while since my Ubuntu days, forgot about the "-server" part

Did you change the port like they did in the article? You should probably keep it on port 22, otherwise you will need to edit the Nagios checks to use the new port.

Also, did you open up/disable the firewall? http://www.howtogeek.com/115116/how-to- ... -firewall/
