# Understanding Telnet

**What is Telnet?**

Telnet is an application protocol which allows you, with the use of a telnet client, to connect to and execute commands on a remote machine that's hosting a telnet server.<br>

The telnet client will establish a connection with the server. The client will then become a virtual terminal- allowing you to interact with the remote host.<br>

**Replacement**<br>

Telnet sends all messages in clear text and has no specific security mechanisms. Thus, in many applications and services, Telnet has been replaced by SSH in most implementations.\

**How does Telnet work?**

The user connects to the server by using the Telnet protocol, which means entering **"telnet"** into a command prompt. The user then executes commands on the server by using specific Telnet commands in the Telnet prompt. You can connect to a telnet server with the following syntax: **"telnet \[ip] \[port]"**

The lack of what, means that all Telnet communication is in plaintext?\
