ElementaryOS uses pantheon file manager, that is part of pantheon desktop and is developed by the same team I guess.
This is the output from nmap:
Host is up (0.000076s latency).
Not shown: 993 closed ports
PORT STATE SERVICE
53/tcp open domain
139/tcp open netbios-ssn
443/tcp open https
445/tcp open microsoft-ds
631/tcp open ipp
902/tcp open iss-realsecure
9999/tcp open abyss
No exact OS matches for host (If you know what OS is running on it, see
http://nmap.org/submit/ ).

Is this the right way I'm using smbclient.
