Again, use the verbose flags for check_ping, then try the same ping  
command it uses (it varies by system). The only explanation I can give  
at this point is that the ping binary you used above isn't the one  
that check_ping is using or that some specific flag is needed on your  
network. You should be able to discover that, and what that flag does,  
through the process of elimination. It could also be some strange DNS  
resolver issue with the ping binary. Running truss or strace on ping  
may provide interesting information if those tools are familiar to you.

This *really* isn't a nagios issue since the plugin is doing the right  
thing. If the above suggestions don't help you, you'll have better  
luck through the support forums for your OS.
