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
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). - Linux NetKit (0.17) April 29, 1996 Linux
