Full Discussion: Find the IP address that a telnet session uses
Top Forums Programming Find the IP address that a telnet session uses Post 12996 by S.P.Prasad on Thursday 10th of January 2002 04:24:34 AM

I tried this objective in SCO Unix with few lines scripting in .profile file:

for IP in `cat IPFile`
do
finger -fb | grep $IP > /dev/null
if [ $? -eq 0 ]
then
echo "You Are Not Allowed To Use Telnet Session In My System"
exit
fi
done


The IPFile contains all the IP's and hosts name in singular line format entry.

kf

KF(1)							    BSD General Commands Manual 						     KF(1)

NAME

     kf -- securely forward tickets

SYNOPSIS

     kf [-p port | --port=port] [-l login | --login=login] [-c ccache | --ccache=ccache] [-F | --forwardable] [-G | --no-forwardable]
	[-h | --help] [--version] host ...

DESCRIPTION

     The kf program forwards tickets to a remote host through an authenticated and encrypted stream.  Options supported are:

     -p port, --port=port
	     port to connect to

     -l login, --login=login
	     remote login name

     -c ccache, --ccache=ccache
	     remote cred cache

     -F, --forwardable
	     forward forwardable credentials

     -G, --no-forwardable
	     do not forward forwardable credentials

     -h, --help

     --version

     kf is useful when you do not want to enter your password on a remote host but want to have your tickets one for example AFS.

     In order for kf to work you will need to acquire your initial ticket with forwardable flag, i.e.  kinit --forwardable.

     telnet is able to forward tickets by itself.
