NAME

tits Tiny Terminal Server

SYNOPSIS

/usr/local/sbin/tits [config-file]

DESCRIPTION

The tits command is a server process which provides telnet(1) or raw access to one or more tty ports as specified in config-file (or /usr/local/etc/tits.conf if no configuration file is specified on the command line).

Any number of telnet(1) or raw clients may connect to a single tits port. Each client will see exactly the same output as well as being able to send keystrokes simultaneously.

tits implements access control using the hosts_access(5) framework to filter incoming network connections. The service name used to look up each port in the hosts_access(5) database is dependent on how the port is specified in the config-file. If a numerical port is specified, the service name is the final component of the pathname used to invoke the program. Thus, this will be tits in normal operation. If the port is specified using a service which needs to be looked up in /etc/services, this service name is used when checking the host_access(5) database.

tits multiplexes the data streams between all configured tty ports and connected clients within a single process. Thus, it minimises system context switching overhead when there is a high I/O load.

tits also features a reverse telnet server which can be used to multiplex telnet(1) connections to another terminal server which is limited to a single telnet(1) connection at any one time. In conjunction with a masterpty client, the reverse telnet server can connect a remote terminal server to a psuedo-tty device on the local system.

BUGS

Only a tiny subset of the telnet protocol specified in the above RFCs is implemented.

At this time, there is no `Control Port' providing supervisory functions for managing a tits process at runtime.
