[Nagios-devel] check_dns segfaults when nslookup returns empty answer
Posted: Tue Dec 09, 2003 12:11 pm
Hi!
In nagios-plugins-1.3.1:
check_dns seems to segfault when nslookup returns an empty answer, e.g. w=
hen=20
querrying a non-resolvable hostname. I know, querrying a nameserver usin=
g=20
it's hostname is probably not what one want to do, but still, it segfault=
s.
root@sentinix:/usr/local/nagios/libexec$ ./check_dns -s non_existent -H \=
=20
a.root-servers.net
Segmentation fault
nslookup directs it's error to stderr, but stdout is completely empty.
I can provide a patch for this, unless of course, anyone hasn't already=20
thought about this??!
Best regards,
