OK, as promised, I'm back with another problem :). Hopefully this will be the last. I now have Nagios 3.2.3 running and things seem fine except for the ping monitoring, which keeps telling me localhost is down, when it's not. Looking into it a bit, it turns out that Nagios can't interpret the ping command output. There is a similar thread here, but the problem is not exactly the same and it is not really resolved anyhow, so I decided to start a new thread.

I have not made any changes to the original configuration files. If you need any further info, please let me know.
Thanks for any pointers I can get on this!
