Setting up Telnet

Installing telnet daemon + client

• Unpack the Netkit-telnet archive and install it by running:

./configure
cd telnetd
make
make install

Creating the /etc/inetd.conf configuration file

• Create a new file /etc/inetd.conf containing:

# Begin /etc/inetd.conf

telnet stream tcp nowait root /usr/sbin/in.telnetd

# End /etc/inetd.conf

Creating the /etc/init.d/inetd script

• Create a new file /etc/init.d/inetd containing:

#!/bin/sh
# Begin /etc/init.d/inetd

check_status()
{
  if [ $? = 0 ]
  then
    echo "OK"
  else
    echo "FAILED"
  fi
}

case "$1" in
  start)
    echo -n "Starting Internet Server daemon..."
    start-stop-daemon -S -q -o -x /usr/sbin/inetd
    check_status
    ;;

  stop)
    echo -n "Stopping Internet Server daemon..."
    start-stop-daemon -K -q -o -p /var/run/inetd.pid
    check_status
    ;;

  reload)
    echo -n "Reloading Internet Server configuration file..."
    start-stop-daemon -K -q -s 1 -p /var/run/inetd.pid
    check_status
    ;;

  restart)
    echo -n "Stopping Internet Server daemon..."
    start-stop-daemon -K -q -o -p /var/run/inetd.pid
    check_status

    sleep 1

    echo -n "Starting Internet Server daemon..."
    start-stop-daemon -S -q -o -x /usr/sbin/inetd
    check_status
    ;;

  *)
    echo "Usage: $0 {start|stop|reload|restart}"
    ;;

esac

# End /etc/init.d/inetd

Setting up permissions and symlinks

• Set the proper permissions by running:

chmod 755 /etc/init.d/inetd

• Create the proper symlinks by running:

        cd /etc/rc2.d
ln -s ../init.d/inetd S40inetd
cd ../rc0.d
ln -s ../init.d/inetd K40inetd
cd ../rc6.d
ln -s ../init.d/inetd K40inetd
