Once a connection has been opened, telnet will attempt to enable the TELNET LINEMODE option. The line ~^] escapes to the normal telnet escape prompt. Similarly, the line ~^Z suspends the telnet disconnects from the remote host ~ is the telnet escape character. When in rlogin mode, a line of the form ~. If a number is not specified, the default telnet port is used. Port' Indicates a port number (address of an application). Host' Indicates the official name, an alias, or the Internet address of a remote host. x' Turns on encryption of the data stream if possible. In this mode, the escape character is set to the tilde (~) character, unless modified by the r' Specifies a user interface similar to rlogin(1).

Opens tracefile for recording trace information. This option may also be used with the open command. When connecting to the remote system, if the remote system understands the ENVIRON option, then user will be sent to the remote system as the value for

If Kerberos authentication is being used, the -k option requests that telnet obtain tickets for the remote host in realm realm instead of f' If Kerberos V5 authentication is being used, the -f option allows the local credentials to be forwarded to the remote system. If escapechar is omitted, then there will be no escape character. Sets the initial telnet escape character to escapechar. d' Sets the initial value of the debug toggle to TRUE. (See the toggle skiprc command on this man page.) This can be useful when connecting to services which use IP addresses for authentication and reconfiguration of the server Uses bind(2) on the local socket to bind it to an aliased address (see ifconfig(8) and the ''alias'' specifier) or to the address of another interface than the Name used is that of the current user as returned by getlogin(2) if it agrees with the current user ID, otherwise it is the name associated with the user ID. Currently, this sends the user name via the USER variable of the ENVIRON option if supported by the remote system. This causes the BINARY option to be negotiated on output.ĭisables the atype type of authentication. L' Specifies an 8-bit data path on output. K' Specifies no automatic login to the remote system. F' If Kerberos V5 authentication is being used, the -F option allows the local credentials to be forwarded to the remote system, includingĪny credentials that have already been forwarded into the local environment.

E' Stops any character from being recognized as an escape character. This causes an attempt to negotiate the TELNET BINARY option on both input and output. Telnet is 8-bit clean bydefault but doesn't send the TELNET BINARY option unless forced. If it is invoked withĪrguments, it performs an open command with those arguments. In this mode, it accepts and executes the commands listed below. It enters command mode, indicated by its prompt ( telnet>). If telnet is invoked without the host argument, The telnet command is used to communicate with another host using the TELNET protocol. Telnet - user interface to the TELNET protocol
