Problem with check_ping

[Networks]

Hey guys ~
I recently ran into this issue myself, unable to find a solution I 
downloaded the newest version of nagios_plugins (4.0) and compiled it. 
The new check_ping worked fine, my problem was caused by updating my box 
and then copying over the nagios install without recompiling (moved from 
rh 8 to rh es3) anyhow I also had issues with the NEWER version of 
check_tcp so I rolled that one back to my older nagios_plugin  version 
and it worked also.

Hope this helps. I'd like to know why this happens as well tho.. I just 
didnt have time to research it.

Josh

As a note: I notcied some of my plugins didn't work since nagios seems 
to capture stdout but not stderror, buy redirecting output with 2>&1 it 
was resolved, my guess is your ping binary may be sending output to 
stderror, just a guess.
