Here is the steps to install Install VPN PPTP Client on CentOS 6
I will be using following variables:
Client OS: CentOS 6.3 64bit
PPTP Server: 192.168.100.1
Username: myvega
Password: CgK888ar$
1. Install PPTP using yum:
$ yum install pptp -y |
2. Add the username and password inside /etc/ppp/chap-secrets:
myvega PPTPserver CgK888ar$ * |
The format will be: [username][space][server name][space][password][space][ip address allowed]
3. Create a configuration files under /etc/ppp/peers directory called vpn.myserver.org using text editor:
$ vim /etc/ppp/peers/vpn.myserver.org |
And add following line:
pty "pptp 192.168.100.1 --nolaunchpppd" name myvega remotename PPTPserver require-mppe-128 file /etc/ppp/options.pptp ipparam vpn.myserver.org |
4. Register the ppp_mppe kernel module:
$ modprobe ppp_mppe |
5. Make sure under /etc/ppp/options.pptp, following options are not commented:
lock noauth refuse-pap refuse-eap refuse-chap nobsdcomp nodeflate require-mppe-128 |
6. Connect to the VPN by executing following command:
$ pppd call vpn.myserver.org |
Done! You should connected to the VPN server now. Lets check our VPN interface status:
$ ip a | grep ppp 3: ppp0: mtu 1456 qdisc pfifo_fast state UNKNOWN qlen 3 link/ppp inet 192.168.100.10 peer 192.168.100.1/32 scope global ppp0 |
If you face any problem, kindly look into /var/log/message for any error regards to pppd service:
$ tail -f /var/log/message | grep ppp Dec 4 04:56:48 localhost pppd[1413]: pppd 2.4.5 started by root, uid 0 Dec 4 04:56:48 localhost pptp[1414]: anon log[main:pptp.c:314]: The synchronous pptp option is NOT activated Dec 4 04:56:48 localhost pptp[1420]: anon log[ctrlp_rep:pptp_ctrl.c:251]: Sent control packet type is 1 'Start-Control-Connection-Request' Dec 4 04:56:48 localhost pppd[1413]: Using interface ppp0 Dec 4 04:56:48 localhost pppd[1413]: Connect: ppp0 /dev/pts/1 Dec 4 04:56:48 localhost pptp[1420]: anon log[ctrlp_disp:pptp_ctrl.c:739]: Received Start Control Connection Reply Dec 4 04:56:48 localhost pptp[1420]: anon log[ctrlp_disp:pptp_ctrl.c:773]: Client connection established.
