This tool is in the Backtrack repositories, so if you want it apt-get install it.
I thought there was a samba service in earlier versions of BackTrack, but it doesn't seem to be on the list of services for version 4, R2.
Having a samba service is very useful for things like booting a virus-infected or otherwise failing windows machine in BackTrack, and then sharing that machine's drives or folders on the network for inspection, file-backup, or virus scanning from a different (probably windows) machine.
`apt-get install samba` and `apt-get install system-config-samba` are the two commands I happened to use to achieve this. It would be nice if these were included in BackTrack by default. Thanks.
* I guess that, since "samba" is a dependency package for "system-config-samba", that simply installing the latter would install both.
* FYI, after installing system-config-samba, the new menu item can be found at System > Samba
