HowTo: Hur jag fick igång PPTP VPN
Postat: 20 mar 2007, 07:37
Jag följde (förgäves) flera guider för att installera en VPN-klient som skulle fixa en PPTP-koppling in till jobbet. Sedan hittade jag följande som fungerade direkt på Ubuntu 6.10:
$ sudo apt-get install pptp-linux
Now you will need to edit the options.pptp file
sudo vi /etc/ppp/options.pptp
and insert the below line:
lock noauth nobsdcomp nodeflate
Next you will need to modify chap-secrets
$ sudo vi /etc/ppp/chap-secrets
add this line:
$USERNAME PPTP $PASSWORD *
where: $USERNAME is your VPN username $PASSWORD is your VPN password
A completed chap-secrets on a default Dapper setup would look something similar to this:
1. Secrets for authentication using CHAP
2. client server secret IP addresses
myusername PPTP mypassword *
You will then need to create a tunnel configuration file:
$ sudo vi /etc/ppp/peers/$TUNNEL
where $TUNNEL is the name you wish to give this VPN connection. Now:
$ sudo vi /etc/ppp/peers/MyVPN
and add the following lines:
* pty "pptp $SERVER --nolaunchpppd"
* name $USERNAME
* remotename PPTP
* require-mppe-128
* file /etc/ppp/options.pptp
* ipparam $TUNNEL
where $SERVER is the IP address or hostname of the VPN gateway where $USERNAME and $TUNNEL are as defined earlier.
The resulting file will look something like this:
* pty "pptp myvpnserver --nolaunchpppd"
* name myusername
* remotename PPTP
* require-mppe-128
* file /etc/ppp/options.pptp
* ipparam MyVPN
The last step you'll need to take is to create a file in /etc/ppp/ip-up.d with the same name as your "peers" file that sets the route to the other network automatically for you:
$ sudo vi /etc/ppp/ip-up.d/MyVPN
which in this example for a class C network will look something like this:
1. !/bin/sh
route add -net 192.168.1.0 netmask 255.255.255.0 dev ppp0
Finalise the process by making the file executable:
$ sudo chmod a+x /etc/ppp/ip-up.d/MyVPN
Provide all your settings are correct, you should be able to start the PPTP connection by running:
$ sudo pon MYVPN
Efter allt ovanstående kopplade maskinen upp sig på VPN-linan och jag kan samtidigt surfa vidare på internet utan problem.
För att starta och stoppa VPN-kopplingen har jag 2 script:
startvpn.sh innehåller bara:
sudo pon MYVPN
killvpn.sh innehåller bara:
sudo kill $(pgrep pptp)
Hoppas det här löser problemen med att få igång PPTP VPN.
$ sudo apt-get install pptp-linux
