Oh, here's one last goodie for advanced users. Get netcat for Windows. It's a program written by Weld Pond and Hobbit, and available from many sites, for example https://download.cnet.com/s/netcat/. It is basically telnet on steroids. For example, using netcat, you can set up a port -- also known as a back door, depending on your motivation -- that will allow people to telnet into a DOS shell. Use this command:
C:\>nc -L -p 5000 -t -e cmd.exe
You can specify a different port number than 5000. Just make sure it doesn't conflict with another port by checking with the netstat C:\>nc -v [ipaddress of target] [port]
Of course you will probably get hacked for setting up this port. However, if you set up a sniffer to keep track of the action, you can turn this scary back door into a fascinating honeypot. For example, you could run it on port 23 and watch all the hackers who attack with telnet hoping to log in. With some programming you could even fake a unix-like login sequence and play some tricks on your attackers. Copyright 2002 Carolyn Meinel.
