Vpn linux

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

See [1] and/or [2] for installation instructions for the various Linux distributions.

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:

pptpsetup --create radboud --server vpn-srv.science.ru.nl --username USERNAME --encrypt --start

• For each website you want to access through VPN give a "route" command. E.g. for access to www.sciencedirect.com:

route add -net www.sciencedirect.com netmask 255.255.255.255 dev ppp0

Notes

• The configuration file /etc/ppp/options contains by default "idle 600". A VPN connection is disconnected if it is idle for 600 seconds
• To use VPN for all connections see:
