Question on nagios install


I’m working on a linux environment and attempting to install nagios for server monitoring.

we have a server set up with ubuntu 12.04 at our production site we need to monitor we have 4 boxes that have ubuntu 10.4 and 2 boxes that have ubuntu 12.04 installed.

I’m wanting to do a simple check on them (currently) where i check for icmp and ssh connectivity. Is there going to be any issues using the older os environment with the server being on a different environment?

linux command i run to install nagios - sudo apt-get install nagios-nrpe-server
