Package: nagios-plugins Version: 1.4.15-3 Severity: minor When neither the -4 nor -6 options are specified on the command-line, one would expect the check_ping plugin to try both (as most programs do). Instead, if it finds an AAAA record for the hostname given, it will *only* try IPv6, and fail if no IPv6 connectivity is available.
e.g. on a fully dual-stacked host: chrisb@cob:~$ /usr/lib/nagios/plugins/check_ping -H www.google.co.uk -w 3000.0,80% -c 5000.0,100% -p 1 PING OK - Packet loss = 0%, RTA = 19.56 ms|rta=19.555000ms;3000.000000;5000.000000;0.000000 pl=0%;80;100;0 but on a machine with IPv4 only: chrisb@squeeze-vm:~$ /usr/lib/nagios/plugins/check_ping -H www.google.co.uk -w 3000.0,80% -c 5000.0,100% -p 1 CRITICAL - Network Unreachable (www.google.co.uk) We noticed this earlier today, when Google started publishing an AAAA record for www.google.co.uk et al. Happy IPv6 day ;) I realise this testcase may stop working after today, but any host that publishes both A and AAAA records should do (e.g. ftp.uk.debian.org) Set to 'minor' severity, since using the -4 and -6 options works, and if you're specifically testing for v4/v6 connectivity you'd be using them. -- System Information: Debian Release: 6.0.1 APT prefers stable APT policy: (990, 'stable'), (500, 'proposed-updates') Architecture: amd64 (x86_64) Kernel: Linux 2.6.32-5-openvz-amd64 (SMP w/2 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) (ignored: LC_ALL set to en_GB.UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages nagios-plugins depends on: ii nagios-plugins-basic 1.4.15-3 Plugins for the nagios network mon ii nagios-plugins-standard 1.4.15-3 Plugins for the nagios network mon nagios-plugins recommends no packages.
