[pptp-server] PPtP linux client

[csa998360 at ait.ac.th]

Dear all,
      I got the problem with pptp linux client. When I 
run " ./pptp SERVER_IP_ADDRESS name USER_NAME 
remotename SERVER_IP_ADDRESS" and then run " route 
add -host SERVER_IP_ADDRESS gw 
GATEWAY_ADDRESS". I got some error

(unknown)[148]: log
[pptp_dispatch_ctrl_packet:pptp_ctrl.c:549]: Client 
connection established.
(unknown)[148]: log
[pptp_dispatch_ctrl_packet:pptp_ctrl.c:655]: Outgoing call 
established.
(unknown)[148]: log[pptp_conn_close:pptp_ctrl.c:275]: 
Closing PPTP connection

On my server side, the log fie /var/log/pptpd.log shows
