Why can't telnet connect to LINUX! Telnet localhost failed to connect locally and was rejected. Telnet, telnet-server and xinetd are installed.

Telnet can't connect under LINUX due to the wrong setting. The solution is as follows:

1. View telnet service, chkcconfig- list view. If the telnet service is added, it will be turned off by default.

2. All xinetd-based services have corresponding files in the /etc/xinetd.d directory.

3. Edit telnet service: change disable to no, indicating that telnet has been started.

4. Restart xinetd service: telnet service is not restarted, there is no telnet service, and telnet service is based on xinetd.

5, check the port number, found that the telnet service has started, command chkconfig-list to check.
