The smbclient command line application included in Backtrack Linux is a staple for pentesting. I would imagine anyone that has done a pentest has used it to quickly verify SMB (Server Message Block) or CIFS (Common Internet File System) shares. The smbclient manpage describes it as a FTP-like client to access SMB/CIFS resources on servers. Below we describe varios smbclient commands in details to provide a basic understanding of its capabilities and what output will look like when using this tool in Backtrack Linux.
In the Backtrack menu under Information Gathering > Network Analysis > SMB Analysis there is a menu item named smbclient which should actually be named smbclient.py. While the smbclient.py script does actually use smbclient it provides a different interface, commands, no switches, etc. making it fairly different than smbclient itself. While both smbclient and smbclient.py are supposed to provide the same end results they don’t because smbclient.py is extremely buggy so I will be writing an article on each so there is no confusion.
When setting up a NFS server its nice to be able to test from your desktop to verify things are working properly. In the current scenario I setup NFS on a BackTrack Linux server and needed to test it quickly from OSX to make sure NFS mounts were advertising properly. Below are a couple quick commands to first display the available NFS mounts and second to mount the NFS drive on OSX to verify functionality.
