Now i just used stranded CMD telnet for this tutorial.
Open up CMD and type in "telnet" without the quotes
Now that will just open up the telnet terminal.
O IP PortExample
o 127.0.0.1 22
Now O basically stands for Open to Then you would type in the IP. Now when your using the telnet terminal if your connecting to a computer on port 23 you dont have to type anything for the port. Due to port 23 being automatic with telnet terminal.
Now say you wanted to connect to another port you would just type that in after the IP
127.0.0.1 port
After you've entered the IP you want to connect to + the port just press enter, and if computer has password and username set then you will have to login.
Now if your connecting via telnet/ftp for malicious purposes, unless you can guess the name you are either going to have to bruteforce it or use a word listI would suggest using THC-Hydra linux has a GUI version but i will later on be making a tutorial with the command line windows version.
So enter in the login info and if you got it right, you will have as much access as the account you login is with is granted.
Now keep in mind 99% of people that have telnet open use loggingSo either bounce your connection off an owned box or use a VPN before you connect.
