Do you want VPN or SSH connect? SSH of course works without problems
Fedora, both as server as well as client. You can use SSH for tunneling
too, as a "lightweight" VPN.
But I would highly recommend that you switch off every telnet daemon!
And just use POP3S and IMAPS instead of the normal daemons without
SSL/TLS encryption. Actual clients on Windows[tm] and Linux do support
these secured services.
I suppose that the S version are just the normal one over a
TLS channel, with Client authentication.
But I thought about SSH and a secure telnet for remote management
like password changes.
