What to do if Linux cannot log in using telnet
The telnet command is usually used for remote login.
The telnet program is a remote login client program based on the TELNET protocol.
The Telnet protocol is a member of the TCP/IP protocol family and is the standard protocol and main method for Internet remote login services.
It provides users with the ability to complete remote host work on the local computer. Use the telnet program on the end user's computer to connect to the server.
Terminal users can enter commands into the telnet program, and these commands will be run on the server as if they were entered directly on the server's console. You can control the server locally.
To start a telnet session, you must enter your username and password to log in to the server. Telnet is a commonly used method to remotely control web servers.
