At the CLI, I want to know how to get a netbios name from an IP address. It seems that every solution that I have found is windows based, or requires me to install something beyond samba. Please tell me that there is a simple "prog-x -somearg 192.168.1.100" or similar to get the netbios name - and that it doesn't require a reconfiguration of my server?
For instance, I would like this to be usable on a desktop system in an ad hoc without having to be run from root.
If your system runs the avahi daemon, then "getent hosts <ip_address>" may return both the hostname and IP address using zeroconf (mdns). It depends on how your nsswitch.conf and host.conf are configured.
You can also run "getent hosts <hostname>". This will also return IP addresses for hosts on the internet. For avahi, add .local to the hostname. E.G.
getent hosts elite.local
192.168.1.106 elite.local
I configure my router to map MAC numbers to IP addresses, which allows me to maintain an /etc/hosts file. Entering "getent hosts elite.local" allows me to conveniently look up another hosts IP address before entering it in /etc/hosts.
