"Who needs an NT license? Not us! We tap into Windows' file and
print service by running The Samba Group's Samba 2.0.x on Linux or
other Unix systems."
"Samba enables users to use file and print services on a Unix
machine exactly as if they were on an NT system, by employing
Windows' own Server Message Block (SMB) protocol. The Samba program
also empowers Unix users to utilize resources on NT domains even
when Unix compatibility programs (such as Network File System
gateways) aren't installed."
"...our informal tests with a Pentium-compiled Samba running on
the Pentium-enabled, out-of-the-box Turbo Linux showed speed gains
in excess of 50 percent over untuned Linux."
