Unix file system on share

[Sivarama Maruti]

Hi,
One of my colleages Installed Samba on Solaris box. He put one directry in
share , that directry is used by the team. Now that guy is no more with us.
we need to put one more filesystem in Share. Can any body explain me how to
configure it? I need to install Samba on another solaris box. How can I get
the solaris version of samba software? How to Install it?
Thanks in advance
Siva
