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
- To use the Windows Terminal Server:
/sbin/route add -net ts2.nwi.ru.nl netmask 255.255.255.255 dev ppp0
- 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:
