Alright slow your role..
This is easy and requires no command line commands to turn the swat on.
Now remember one thing the swat program doesn't go with the redhat 8.0 you have yours comes with the samba client and samba server which doesn't include samba-swat your going to have to unistall your package.
go to this link
Know select new samba security patch the latest
you should come to list select redhat 8.0
Samba server 2.2.7
Samba-common(they state it includes everything) 2.2.7
The reason your deleting the original samba is that the up date version for some reason doesn't not run with the one you have redhat 8.0 comes with I believe 2.2.5
the version you looking for is 2.2.7
download all four and install it.
After downloading and installing you may have to restart your computer for this to take effect.
For some reason mine would not show up until I restarted the computer.(This is the only program I've had to restart the computer in order for it to show up).
1.go to the redhat > server settings > go down till you come to the swat program make sure you check the box
if so you should be good to go.
2. Open your browser and type in http://localhost:901/
you will know see a box asking for name and password
it should be root and your root password by default.
3. from know on you should be able to go into start button(REDHAT ICON) >extras > server settings > Samba configuration to get to swat.....
The reason I feel most people have trouble setting up samba-swat in this room USERS ARE using a purchased Redhat 8.0.
Why'll I'm using a distro copy which probably doesn't come with all the packages that the purchased copy does.
So what I'm telling you is the purchased copy has more programs to install then the base distro does.
Like an added incentive for buying Redhat 8.0.......
Later have fun.....
