Hello
first of all, ditch telenet if you can, and use SSH. It is the exact same interface and does the same thing, but it is MUCH more secure. Telenet sends your passwords over the network in plain text, ssh encrypts everything. Google Putty for a free client
fire up a terminal and do this:
service sshd start
chkconfig sshd on
Aside from that, ive never used telenet because of its suckey security, so i cant help much if you REALLY need it. (ssh is telenet with encryption)
moving on to samba. It would probally be more worth your time to learn to configure it via command line. You will find that doing it this way will work the same way on every distro, so you wont have to learn different tools for different distros. Also, i distrinctly remember getting pissed off becasue the gui tool RH had would reset the workgroup and other settings every time it was run, and I got really sick of telling it the same things over and over again.
use any text editor you are happy with to open
/etc/samba/smb.conf
spend about 10 minutes reading this file. It is very well commented, so you should be able to figure out what you need to do by just reading it and setting the options you need. if you need some more to read, go to your console and type "man smb.conf" You should get some more detailed instructions there.
make sure its running btw
service smbd start (or this might be service samba start, its been awhile)
chkconfig smbd on (or again, it might be chkconfig samba on, did i mention its been awhile?)
If you have directries that complain about permissions, keep in mind that unix permissions apply to samba directories. I useually create a /home/share direcotry, chmod it 0777, and use it as my sharing drive.
Dont be scared of that command line stuff, it will be your best friend when you get to know it. You can set up one config file that works, and jsut copy it to the next machine if you want the same config on 1000 machines. doesnt that beat point and click?
Hopefully that will get you started, if you need more detail tell us EXACTLY what you are trying to make samba do and im sure sombody can help you out. share or user sercurity, what directories do you want to share, ect.
