The following are some of the benefits of telnet:
# It allows a user to log in to a remote computer and execute programs. # It is a common utility in the TCP/IP protocol suite and is thus as widely implemented many platforms. Therefore a telnet client program is usually easily available.
# It can be used to administer most enterprise class network equipment by connecting to the device and executing built-in configuration and status programs. # It may be used to debug network services such as SMTP, IRC, HTTP, FTP or POP3. The person testing would use telnet to connect to the service and so send commands to the server and consequently examine the responses in order to make analyses. How to exploit the benefits is a little involved and problem specific. For example, the following links and indicated sections show how it may be used to debug SMTP and POP3 e-mail protocols:

Telnet use port number 23,and connected to TCP
*encryption
Telnet operates over TCP Port 23.
Because the telnet session is in clear text and programs can capture the passwords to log in to telnet sessions.
Telnet is a protocol for transferring plain text over TCP .
Telnet use port number 23,and connected to TCP
Telnet use port number 23,and connected to TCP
what osi layers use telnet connections for remote use
Windows: Open start menu, click "Run", type in "telnet" Linux: Open a Terminal window, type in "telnet"
*encryption
SSH is more secure than Telnet.
If you want better security, use secure shell (ssh) instead of telnet. Actually, don't use telnet at all if possible, as it transmits all information in plain text.
Telnet is a Network layer protocol. It is used to create connection remotely.
One disadvantage of telnet is that it is not secure, meaning people can read your passwords and other sensitive information. It is outdated and has no colors. It is fairly hard to use.
Telnet is similar to HTTP and FTP in that all three use the TCP protocol for connection-oriented
Telnet does not encrypt anything; that is why it is too insecure to use as a network protocol.
To use a Telnet app on an Android smartphone, first, download a Telnet client from the Google Play Store, such as "Termux" or "JuiceSSH." Open the app and enter the Telnet command along with the desired hostname or IP address and port number (e.g., telnet example.com 23). Once connected, you can interact with the remote server using the command line interface. Make sure your phone is connected to the internet for the connection to work.
