As it turns out, because Mythbuntu already has Samba built in, it is easy to make it a file server in your home network by using the same tool. First, identify a place where you want to open up a new folder for file sharing. In this example, we’ll do “/fileserver/”. Then, let us issue the following command to edit the Samba config file.
su pico /etc/samba/smb.conf
Note the “su” command; it will require you to put in your password before editing. Once the text editor pico loads up, add the following section at the end of the configuration file.
[files] comment = Files path = /fileserver/ public = yes writable = yes create mask = 0660 directory mask = 0770 force user = mythtv force group = mythtv
Once this is done, restart the samba daemon from your command line.
You should now be able to access the new “files” samba share from another computer on your network.
