CentOS - Oct 2009 - Testing remote machine status in a script ?

Hi,

I'd like to test the status of a remote machine in a script. Something like:

IF remote machine is switched on / connected to the network...

... THEN launch backup.

How would you go about that?

Cheers,

Niki

Use ping and test the result; perhaps something similar to this:

 case `ping -qnc 1 10.0.0.2 2>&1` in
   *'100% packet loss'*)
        exit 1
        ;;
 esac

See the script at the bottom of
http://www.digitalpeer.com/id/configuringa for more info.

I always recommend backuppc (either from http://backuppc.sourceforge.net/ or the
package in epel) because it does all this for you and gets it right.
