this small howto leads you through setting up the M$vpn pptp connection as used in the students' hostel, fantoft, bergen, norway. it is derived from the howtos found at uib.no, focuses on debian systems and tries to be easy to follow. if you encounter problems with this howto, feel free to submit corrections to felix aet salfelder doht org.

• make sure pptp-linux and ppp is installed.

   apt-get install pptp-linux ppp
  
   write the following stanza into /etc/network/interfaces.
  iface uib inet dhcp
          # fix routes.
          post-up route add -net 10.0.0.0 netmask 255.0.0.0 gw $( route -n |grep '^0.0.0' |awk '{print $2}' ) dev $IFACE
          post-up route del default dev $IFACE
          # dial using ppp
          post-up pon MY_UIB_PEER
          pre-down poff MY_UIB_PEER
  
  
   put the following into /etc/ppp/peers/MY_UIB_PEER. replace MY_USERNAME with your login.
  
  defaultroute
  noauth
  nobsdcomp
  nodeflate
  #debug
  #require-mppe-128
  name MY_USERNAME
  
  # thats the name used in pap-secrets
  remotename  MY_REMOTE_NAME
  
  # here the name of the host to be connected
  pty  "pptp uib-vpn-gw  --nolaunchpppd"
  # pty  "pptp uib-vpn-gw --loglevel 2 --nolaunchpppd"
  
  
   add the following line to /etc/ppp/pap-secrets replacing the respective strings.
  make sure this file is 600.
  MY_USERNAME MY_REMOTE_NAME MY_PASSWORD  *
  
  

now do ifup eth0=uib to switch on and ifdown eth0 to switch off the interface.

if you use ifplugd (which you want!), you add

	test1 peer address 10.10.80.1 source MY_IP_ADDRESS mac 00:0f:f7:e0:3b:00
