Package: nagios-plugins-basic Version: 1.4.16-1 Severity: important User: debian-...@lists.debian.org Usertags: debian-edu
In Debian Edu, we use check_ping from the nagios-plugins-basic package to check if a host is responding. The Nagios configuration is generated using the sitesummary package. With the Wheezy version of Debian Edu, the check_ping nagios plugin started to fail, and I tracked it down to the fact that check_ping try to use ping6 to reach the host in question, while earlier it used ping. The DNS host name in question only resolve to an IPv4 address, but ping6 is tried nevertheless: root@tjener:~# host tjener.intern tjener.intern has address 10.0.2.2 root@tjener:~# /usr/lib/nagios/plugins/check_ping -H tjener.intern -w 10,10% -c 10,10% /bin/ping6 -n -U -w 10 -c 5 tjener.intern CRITICAL - Could not interpret output from ping command root@tjener:~# The issue seem to be similar to the ones reported in <URL: http://bugs.debian.org/597068 > and <URL: http://bugs.debian.org/629640 >, but those reports seem to be related to problems with hosts where AAAA records are present. This is not the case here. Could you please change check_ping to use IPv4 ping if no AAAA entry is present in DNS? -- Happy hacking Petter Reinholdtsen -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
