Questions tagged [telnet]

Telnet is an old protocol for bidirectional interactive text-oriented communication with remote hosts via virtual terminals. It is defined in rfc854. On modern UNIX-like systems it is replaced with more secure and flexible SSH protocol.

Telnet is a network protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communications facility using a virtual terminal connection. User data is interspersed in-band with Telnet control information in an 8-bit byte oriented data connection over the Transmission Control Protocol (TCP).

Shell example:

telnet website.com 80 # telnet to the website with port 80

Then HTTP methods can be executed like below

GET /index.html
