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 intentionally 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 attempts 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 messages.

HISTORY
The writed command was developed at MIT in conjunction with Project Athena and is essentially a hackup of fingerd(8).
