[Ferenc Wagner]

Package: nagios-plugins-basic
Version: 1.4.5-1etch1
Severity: normal

Hi,

Please consider this:

$ host -t any lipton.aai.niif.hu
lipton.aai.niif.hu  	A	193.225.14.195
lipton.aai.niif.hu  	AAAA	2001:738:0:701:80:C1E1:EC3:0
$ /usr/lib/nagios/plugins/check_ntp -H lipton.aai.niif.hu -v

overall average offset: nan
NTP OK: Offset nan secs|offset=nan

This isn't serious, since one uses IP addresses anyway, but still a bug.
Sure the client doesn't respond to IPv6 packets, but its offset isn't NaN.

Feri.
