Top Forums UNIX for Dummies Questions & Answers how to logging telnet (-n tracefile) Post 302468746 by jim mcnamara on Wednesday 3rd of November 2010 05:46:20 PM

That is for a tracefile, not logging sessions.
You need to create an interposer process, an alias maybe
This only works for outbound telnet -- not when someone connects to your system.
create a script called /usr/local/bin/telnet that does something like this:
Code:
#!/bin/ksh
umask 000     
[ ! -d tmp/log  ] && mkdir /tmp/log  2>&1> /dev/null
script -a /tmp/telnet.log.$$
/usr/bin/telnet  $*
exit 0

next in /etc/profile
Code:
alias telnet=/usr/bin/local/telnet

Users have to login again to activate this. When a user types "telnet somenode"
the system will telnet to there and record the entire session in a file in /tmp/log

Is this what you mean -- keylogging?

NAME
rxtelnet -- start a telnet and forward X-connections. SYNOPSIS
rxtelnet [-l username] [-k] [-t telnet_args] [-x xterm_args] [-K kx_args] [-w term_emulator] [-b telnet_program] [-n] [-v] host [port] DESCRIPTION
The rxtelnet program starts an xterm window with a telnet to host host. From this window you will also be able to run X clients that will be able to connect securely to your X server. If port is given, that port will be used instead of the default. If setting up the X forwarding failes, rxtelnet will still telnet in to the remote host, but without X forwarding. The supported options are: -l Log in on the remote host as user username. -k Disables keep-alives. -t Send telnet_args as arguments to telnet. -x Send xterm_args as arguments to xterm. -X Send kx_args as arguments to kx. -w Use term_emulator instead of xterm. -b Use telnet_program instead of telnet. -n Do not start any terminal emulator. -v Be verbose. EXAMPLE
To login from host foo (where your display is) to host bar, you might do the following. 1. On foo: rxtelnet bar 2. You will get a new window with a telnet to bar. In this window you will be able to start X clients. SEE ALSO
