To configure a telnet server with xinetd, install xinetd as well. Poor telnet, it used to be the cool kid on the block. telnetd via systemd requires only the inetutils package. A telnet server can be configured with systemd sockets or xinetd. To mitigate this, only connect via e.g a VPN when the data passes through untrusted networks. When I telnet from my Linux server: telnet PublicIP 80. On my Linux server, HTTP (80) is enabled but not telnet. I'm not sure if telnet is enabled but the owner says it is. This public IP has got HTTP (80) enabled on it. Telnet is using an unencrypted connection which is not secure as connections can easily be sniffed and even manipulated. Here's the issue: I am trying to telnet some public IP on port 80 from a Linux web server (Red Hat). Telnet is the traditional protocol for making remote console connections over TCP, it is mainly used to connect to legacy equipment nowadays.
