I'm having a problem with my Linux Server (SuSE 7.0). Someone has tried to

Telnet (from Windows) with extra commands behind the telnet command. He/She
can access my Linux Server without Username and Password.

How to make the security of my Linux Server better ?


First, turn off telnet, block the port, and remove the telnet server package. I suggest using SSH as it solves a lot of telnet issues and provides a non plain text solution as well as secure copy. Also there are SSH clients(I have yet to see the server side) for Windows. I have tried out a couple and found that penguinet ( ) is the best despite being a payfor program.
