[Nagios-users] Hey I was wondering about the check_ping from the newest stable plugins.
I have compiled all nagios plugins many times but on the last time this what happens: nagios-plugins-1.4.16.tar.gz I compile with no errors and then when nagios do a check it states: CRITICAL - Network Unreachable (repo.ngtech.co.il) while from command line linux ping everything works fine! also I compiled my own script in ruby perl and python and all of them are not stating anything about Network Unreachable. Is this a regression from older and newer versions of nagios_plugins?? Since they work at the same time I run my own script and it states the everyting is OK which means 100% no packet loss I am a bit confused about it. How is it possible for the basic check_ping written in c to not work and the scripting languages scripts to work fine? it's not permissions since it states Network Unreachable. it's must be another issue either in nagios or the code somewhere. Can anyone test it please and make sure that my assumptions are right? Eliezer -- Get 100% visibility into Java/.NET code with AppDynamics Lite!

Re: [Nagios-users] Hey I was wondering about the check_ping from the newest stable plugins.
Forgot to show the command: # /usr/local/nagios/libexec/check_ping -H repo.ngtech.co.il -w 100.0,20% -c 500.0,60% -p 10 CRITICAL - Network Unreachable (repo.ngtech.co.il) # /usr/local/nagios/libexec/check_ping -H www1.ngtech.co.il -w 100.0,20% -c 500.0,60% -p 10 PING OK - Packet loss = 0%, RTA = 17.40 ms|rta=17.395000ms;100.00;500.00;0.00 pl=0%;20;60;0 Which is odd in any way you can think off.

JFTR (we clarified this on IRC): * Eliezer Croitoru elie...@ngtech.co.il [2013-08-09 17:23]: which is a bit weird why is it using ping6 for a simple ping by default? Hos is the check_ping recognises that there is a need for ping6 ?? the host dosn't even has ipv6 connectivity.. There's no sensible way to detect the availability of IPv6. The plugin could auto-fallback to IPv4 if IPv6 fails, but so far users are expected to simply add the -4 flag in IPv4-only environments (or to use check_icmp).
