DNS CRITICAL - '/usr/bin/nslookup -sil' msg parsing exited w

[brandonb110]

I changed our DNS server for Nagios this morning. Ever since I am gettign this error with our DNS servers "DNS CRITICAL - '/usr/bin/nslookup -sil' msg parsing exited with no address." I changed the DNS serevr back on Nagios to the original one but the error is still there, I have restarted nagios but to no avail. Seems like it should just be a simple reload of someting but I am not sure. Any help would be greatly appreciated.

If you run the check from the cli, do you get the same error?

Code: Select all

/usr/local/nagios/libexec/check_dns -H www.google.com -s <ip of ns1-cache or other dns server>

Yes, I get the same message and also tried a nslookup and get this results:

nslookup: parse of /etc/resolv.conf failed

my resolv.conf is:
nameserver xxx.xxx.xxx.xxx
nameserver xxx.xxx.xxx.xxx

The issue has been resolved, not sure why but I uploaded a new resolv.conf witht he same settings and it works great now.

Thanks
