To disconnect VPN PPTP connection simply gracefully kill pppd daemon by using the below command:įollowing the logs we can see that pppd module exited gracefully: Use ip to see its configuration:ģ: ppp0: mtu 1396 qdisc pfifo_fast state UNKNOWN qlen 3 Once the VPN connection is established correctly a new network interface will be create. Jan 7 17:55:44 localhost pppd: MPPE 128-bit stateless compression enabled Jan 7 17:55:44 localhost pptp: anon log: buffering packet 7 (expecting 6, lost or reordered) Jan 7 17:55:44 localhost pppd: CHAP authentication succeeded If the PPTP VPN connection was established correctly your should see output similar to the one below: Enter the below code into a file called linuxconfig while replacing VPN server IP, name and ipparam directives:Īll is now ready to establish PPTP VPN connection:Ĭheck /var/log/messages for any errors or warnings.

# echo 'admin PPTP 00000000 *' > /etc/ppp/chap-secretsĪt this stage, using the above VPN connection information we need to create peer VPN config file and save it into /etc/ppp/peers/ directory. Now, we need to add CHAP credentials as provided above into /etc/ppp/chap-secrets file:

In the next step we will load a connection tracking support for PPTP module which is required in order to correctly establish PPTP VPN connection: Let’s begin by installation of PPTP client: PPTP VPN server IP or domain: 123.123.1.1.Connection name: linuxconfig ( can be any descriptive name ).Replace the bellow PPTP VPN information to align with your PPTP VPN server settings: Below you can find connection details which will be used as an example.
