Non-computer geeks might want to skip this one.
Samba allows you to access Linux file systems from Windows networks--very useful if you have a mixed collection of PCs around the house, as I do. I have installed Samba on previous Ubuntu Linux versions, and after a certain amount of struggle, usually managed to get it working after a small amount of editing the smb.conf file and exasperation.
Something that has been added recently to the available Linux packages is system-config-samba, a GUI that significantly eases configuring the smb.conf file. It appears that you still need to restart the smb daemon from the shell after you use the GUI: sudo restart smbd. Nonetheless, the GUI is certainly easier than trying to get all the magic incantations in the smb.conf file.
One thing that I wanted to do was to have Windows network access to the Windows file system that is on the same hard disk as the Linux box. (This is a dual boot system.) I thought that I would just set up a symbolic link from my home directory to the Windows file system (which is located under /media), but it turns out that Samba does not seem to like symbolic links, and I can't make a hard link from the home directory to the Windows file system. Instead, you have to add the Windows file system to the Samba list.
