Making TightVNC secure in connecting to Fedora 9

Hi I'm new to Linux and installed Fedora 9 on a dell server for the 1st time. We needed outside consultants to be able to connect to this particular server and do some install work. They can have the root password.

I want to use TIGHTVNC to enable them to connect securely -
I have put the server on a public IP and opened up our firewall! (big security risk!).

I'm really not sure of the best method for these guys to connect - they need full access but I've opened up ports 22, 23, 80 and wow think I'm creating a big headache for myself.

So what do you suggest is the best method to allow externals to connect.
Also I'd like the VNC Client to prompt for a user name and password but that doesnt seem to happen.

Also what happens if the linux box user is in the LOGIN prompt - can you still use VNC to create a session. I've configured vncservers and added users but I'm worried I'm wide open to attack!

If you want a vnc-like solution, then I'd strongly urge you to look at freenx which automates tunneling of vnc over ssh in a really slick way. This way you ONLY open port 22, and have the full benefits of encrypted logins with ssh.

Certainly NEVER open port 23 for telnet... you deserve everything you get if you do that!
