- There is a program on sunee.waterloo.edu (129.97.50.50) in
- pub/wattcp. It is called telnetd and it runs on a PC with an
- Ethernet card and a packet driver interface to the card. Basically
- the program runs on a PC "listening" to the Ethernet port. One
- can telnet from a remote machine (I tried from a Sun 3/60 and it
- works) to the PC that is running telnetd. Once connection is
- established then whatever is typed on the remote computer is echoed
- on the PC and the output is also sent to the remote machine. When
- I tried it from the Sun I started a telnet session in a window
- (under X windows) and telnetted to the PC (which was already running
- telnetd) and after connection was established I had the DOS prompt
- in a window on the Sun !
-
- Couple of points to be mentioned here:
- - Security is extremely weak in telnetd. The only security is in
- the form of a password that is [optionally] required of any user
- attempting to connect to the PC. The password is stored in an
- non-crypted form in the config file on the PC. The online documen-
- tation makes a note of the weak security.
- - When the remote machine closes the telnet session it reboots the
- PC
- - I have not yet tried running the telnetd program under Windows 3.1
- I shall try it out sometime today.
- - The telnetd program takes over the PC when waiting for incoming
- telnet requests i.e. the PC can't be used for anything else
- - I am not sure if multiple incoming telnet requests can be
- handled (I have not read the manual completely yet).
