Here is a guide to learn how to find and log into a host using Telnet.

Steps

1. 1 Download one of the most essential tools. Before you start hacking, you will need to download a port scanner. One of the most powerful and free port scanners is Nmap.If possible, make sure you set up a graphical interface with it. It comes with a Windows installer.
2. 2 Using Zenmap. When loading Nmap, the "Zenmap GUI" will also be loaded with it. Open it, once you find it, enter the Internet Protocol (IP) address of the computer you want to hack into the "Target" field. Let's say you want to scan a range of IP addresses, then you need to enter the starting IP address, then (without spaces) a dash (-) and the end of the last IP address. For example, if you want to scan from 192.168.1.100 to 192.168.1.299, then you must enter 192.168.1.100-299. From the "Profile" menu in Zenmap select "Intense scan" if not already selected. Click Scan and watch the program scan your computer or device for open ports. Watch the output of Nmap until you see some green words. These are open ports on a computer or device. If port 23 is open, the device can be cracked unless a password is set.
3. 3 Start Telnet program. For Windows: Click Start -> Run (or Windows Key + R) and enter Telnet in the box. This will open the Telnet screen.
4. 4In the Telnet field enter "o IPAddressHere PortNumber"
5. 5 You need to use the IP address where you found port 23 open. If you do not enter the port number, it will be assumed that you mean 23. Now press Enter to connect.
6. 6 Fool around with the device you're connected to. Basically, just fool around with the system here.

Tips

• ? / h - help: Print help information
• c - close: close the current connection
• u - unset: disable options
• q - quit: Telnet outputs
• There is more than just 1 port. Port 25, for example, is what computers use to send email.
• sen - send: send strings to servers
• These are the commands for Microsoft Telnet:
• d - display: displays the parameters of the operation
• st - status: print status information
• set - set: installation options
• Y You can also use Command Prompt (command line) for hacking. But instead, to log into someone's remote computer using Telnet, you put "telnet ipaddress portnumber".
• o - open hostname [port]: connect to hostname (default port is 23)
