Here is a guide to learn how to find and log into a host using Telnet.
Step 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 out there is Nmap. If possible, make sure you set up a graphical interface with it. It comes with a Windows installer.
Step 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.
Step 3. Start the Telnet program
For Windows: Click Start -> Run (or Windows Key + R) and enter Telnet in the box. This will open the Telnet screen.
4 In the Telnet field, enter "o IPAddressHere PortNumber" If you do not enter the port number, it will be assumed that you mean 23. Now press Enter to connect. Basically, just fool around with the system here.
Step 5. You need to use the IP address where you found port 23 open
Step 6. Fool around with the device you are connected to
4 In the Telnet field, enter "o IPAddressHere PortNumber"
If you do not enter the port number, it will be assumed that you mean 23. Now press Enter to connect.
Basically, just fool around with the system here.
