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 HTH, -Roberto
