writed(8)

NAME

writed - remote write server

SYNOPSIS

writed

DESCRIPTION

Writed implements a very simple protocol that allows a

write(1) program
on one host to connect up to one on another host, allowing

communications
across the network. The details of this protocol are inten

tionally not
described in this man page in order to discourage fraudulent

usage. This
constitutes a bug.

Writed is meant to be run from inetd(8) listening for TCP

requests on
port 811.

SEE ALSO

write(1)

BUGS

Connecting directly to the server from a TIP or an equally

narrow-minded
TELNET-protocol user program can result in meaningless at

tempts at option
negotiation being sent to the server, which will foul up the

command line
interpretation. Writed should be taught to filter out IAC´s

and perhaps
even respond negatively (IAC WON'T) to all option commands

received.

No attempt is made to determine the authenticity of users

sending mes
sages.

HISTORY

The writed command was developed at MIT in conjunction with

Project
Athena and is essentially a hackup of fingerd(8).
