telnet

NAME

telnet - Windows user interface to the Telnet protocol

SYNOPSIS

telnet [-a] [-e escapeChar] [-f logfile] 
	 [-l user] [-t term] [host [port]]
telnet [-h]

DESCRIPTION

The telnet(1w) Windows command-line utility is used to communicate with a remote computer using the Telnet protocol. The host argument specifies the name or Internet Protocol (IP) address of the computer to connect to, and port specifies the port number to be used (by default, 23). If telnet is run without the host argument, it enters command mode, indicated by its prompt (telnet). In this mode, it accepts and runs the Telnet commands listed later in this topic. To enter command mode while connected to a remote computer, type the escape-key sequence (by default, CTRL+]).

The telnet command accepts the following options:

-e escapeChar

The character used to enter the Telnet command prompt.

-f logfile

Specifies the name of the file to which the Telnet log is written for this session. If you do not specify the path of the file, it is created in your current directory.

-l user

The user name to use in logging onto a remote system. The remote system must support the ENVIRON option.

-t term

The type of terminal to use for the connection. Supported terminal types are VT100, VT52, ANSI, and VTNT.

-a

Attempts automatic log on. Same as the -l option, except that the current user's name is used to log on.

-h

Displays Help information.

o[pen] host [port]

Connects to host on the specified port (port 23 by default). The host argument can be the name or IP address of the remote computer.
