dl it and #rpm -ivh samba-swat............. as root
make sure it is running after install and point your browser to 127.0.0.1:901
IMHO, i would stay away from swat. I have found the GUI to be far more difficult than the config file. Just open the /etc/samba/smb.conf file in a text editor and make some changes.
also, you can go to the accessories-add/remove packages in your menu to have it installed/uninstalled from your RH9 cd's
