When trying to ssh on FQDN, the resolving fails :
[Jonas@jonas ~]$ ssh -l root webserver.jocan.local
ssh: Could not resolve hostname webserver.jocan.local: Name or service not known
or I get this :
reverse mapping checking getaddrinfo for asterisk.jocan.local [192.168.1.150] failed - POSSIBLE BREAK-IN ATTEMPT!
[root@jonas jonas]# cat /etc/resolv.conf
# Generated by NetworkManager
192.168.1.5 is the DNS-server (not DHCP-server) which has FQDN-IP mappings...
The DHCP-server is a Zyxel router which gives 192.168.1.5 as DNS-server (option 6).
So why is DNS-resolving failing ?
