  1. You can use the command last |grep ppp

    The above command uses last to display all logins of users. As all PPTP VPN are connected through ppp0 / ppp1 / pp2 / ... , you can get VPN user access history.

    Sample result:

    root@www:~# last |grep ppp
user1  ppp0         <client-IP-address>    Mon Jul  7 23:45   still logged in
user2  ppp0         <client-IP-address>    Mon Jul  7 22:59 - 23:08  (00:09)
user3  ppp1         <client-IP-address>    Mon Jul  7 22:58 - 23:01  (00:03)

  2. ifconfig should return the ppp[X] interface when you have a connected user. Use that with who and last (grep with 'ppp' to find out users who are connected via VPN) , and it should provide plenty of information to cross reference.
