SAMBA is primarily for windows filesystems (hence the name SMB = server
message block, the very chatty windows protocol). Linux - Linux sharing
is better accomplished via NFS - network file system. Take a look at :
tldp.org/HOWTO/Networking-Overview-HOWTO-5.html or try some
googleage.

None of the links are working. Only the Red Hat responded but redirected to
a main page.

But I found out something about it. Even shared a folder :)

I am glad you got it working... Though if Linux to Linux I use SSH/SFTP both
built tight into gnome.
