[Nagios-users] check_icmp/ping works but native ping fails
Looks like I need an education here. check_icmp and check_ping can check a particular device but native ping fails. Any help with understanding this would be great..

What does fails mean in this context? Timeout? No route to host? Does this happen for all hosts, or just for one host? Does it happen for local hosts on your own subnet as well as for remote hosts behind a router?

Any help with understanding this would be great.. check_icmp uses it's own sockets code. check_ping is just a wrapper for 'native ping' (i.e. /bin/ping). if check_ping works, regular old ping must as well. You can see the flags the check_ping is passing to /bin/ping by passing verbose flags -- $ ./plugins/check_ping -H localhost -w 10,10% -c 50,50% -vv CMD: /bin/ping -n -U -w 10 -c 5 localhost PING OK - Packet loss = 0%, RTA = 0.04 ms 10.00:10% 50.00:50% -- Marc -- ___ Nagios-users mailing list Nagios-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null

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. -- Marc -- ___ Nagios-users mailing list Nagios-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null
