remtty(1) - Linux man page

Name

remtty - access a TCP port through a TTY (remote-tty)

Synopsis

remtty [-hvVcx] [--help] [--version] [--verbose] [--config remtty.conf] [--comm commprog]

Description

remtty connects to a TCP port on another machine and makes this connection available through a pseudo tty (pty(4)). Any communications program can then handle this pty as a tty. This allows you to use Access Servers with direct access to the modems (such as Cisco NAS) as ordinary dial-out modems, as if they were connected to the local machine.

-c, --configremtty.conf: Load the file remtty.conf as configuration.
-x, --comm commprog: Creates the TCP connection, opens the pty and runs /bin/sh with the option '-c commprog'. Every occurence of '%p' in commprog is replaced by the allocated pty.
-v, --verbose: Show verbose messages.
-V, --version: Display version and exit.
-h, --help: Display help and exit.

Configuration File

The configuration file defines the hosts that are connected as well as a simple chat script. Lines starting with a '#' are comments. Hosts are defined as:

host: hostname:port

When the port is omitted, connections go to port 23 by default.

Multiple hosts can be specified. When a host cannot be reached, 'remtty' tries to connect to the next host.

Chat script lines are of the form

chat: "expect", "answer"

When expect is received, 'remtty' sends answer. This allows to create simple 'Username:'/'Password:' chat scripts to log into NAS. A connection is considered successful only when there are no more chat script lines. expect and answer may contain the characters \r and \n.
