With netcat you can do whatever you want, but that's not a good
thought IMHO. Use ssh instead. But this little idea came to mind,
works with ba(sh) (use cygwin on Win)
#! /bin/bash
LOGIN=buffalo
PASSWORD=bill
while :
do
echo -n "login: "
read login
echo -n "password: "
read password
if [ $login = $LOGIN ] && [ $password = $PASSWORD ]
then
/bin/bash -i
else
sleep 5
fi
done
$ while :; do nc -l -p 2000 -e script.sh; done
