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).
