Configuring a PPTP VPN connection in Linux
To configure a PPTP VPN connection in Linux you need at least the following:
- Read science.ru.nl instead of sci.kun.nl. Pictures are before the DNS rename!!!
- An internet connection
- A provider with GRE support (default)
- A cabel/ADSL router (if applicable) with GRE support (default)
- A username and password
PPTP VPN in openSuSE 11.1
- Install the "pptp" package using YaST
- Become root using the "su" command
- Create a ppp0 interface with the following command:
/usr/sbin/pptpsetup --create radboud --server vpn-srv.science.ru.nl --username USERNAME --encrypt --start
- For each website that you want to access through VPN give a "route" command. E.g., for access to www.sciencedirect.com:
/sbin/route add -net www.sciencedirect.com netmask 255.255.255.255 dev ppp0
PPTP VPN in openSuSE 11.2
- Click on the network manager in in the systemtray and select 'manage connections'.
- Open the tab that says 'VPN' and click add > pptp.
- Fill in a connection name, for example 'Radboud'.
- Gateway is vpn-srv.science.ru.nl.
- Username and password are your standard for the science.ru.nl domain.
- (The IP address tab should say 'Configure: Automatic (VPN)'.)
- Click the 'advanced' button and enable 'use MPPE encryption'.
- Click 'ok' everywhere to close the menus. The vpn connection is now configured and should be available in the
list of the network manager in the system tray.
- The configuration file /etc/ppp/options contains by default "idle 600". A VPN connection is disconnected if it is idle for 600 seconds
- Use /sbin/ifconfig to check wether the ppp0 interface exists
- Use /usr/sbin/traceroute www.sciencedirect.com to check wether VPN is used for access to this site
- To use VPN for all connections see:
