sudo apt-get install network-manager-pptpafter installing this package and restarting gnome panels you'd be able to connect to your windows vpn server through gnome nm-applet , unfortunately there's a bug who've reported all around the world (whom i experienced as well) you if you configure your ethernet adapter to use static ip , you won't be able to see the configuration , so you need to put it on roaming mode , and if you need to connect to a default gateway or something you need to install a DHCP server or something equivalent in your network , there's also another way which i suggest you over the original way , lol .
which is by using pptp-linux
you need to make a ppp connection and the syntax is something like
pppd pty "pptp <hostname> --nolaunchpppd <pptp options>"which hostname is the ip address or the domain address of your vpn server you can use it like this :
first of all install the package which is called pptp-linux
sudo apt-get install pptp-linux$connection_name= your vpn name (which is not important at all)
$name = your vpn connection username
$hostname = your vpn server address
$domain = the authentication domain name
$password = your password for sure
sudo nano /etc/ppp/peers/$connection_nameenter the following information in the file below:
pty "pptp $hostname --nolaunchpad"
name $domain\\$name
remotename PPTP
file /etc/ppp/options.pptp
ipparm $connection_name
then save and exit nano
now you need to configure the file chap-secrets which contains the user name and passwords for pptp
sudo nano /etc/ppp/chap-secretsadd such line in the end of the file :
$domain\\$name PPTP $password *and then try it with
pon $connection_name
if it didn't work check whether you've configured your file /etc/ppp/options.pptp correct or not
for a regular windows based pptp server it should look something like this:
lock noauth nobsdcomp nodeflateif you want to further diagnose your connection you can use
pon $connection_name debug dump logfd 2 nodetach instead of
pon $connection_name of course
tell me whether it's working or not
also note that , for further instructions or assistance of course you can always visit
http://poptop.sourceforge.net/ or join the channel #pptp in irc .
P.S: you can connect to your server this way , but
it does not change your routing path (like what windows vpn do in default) but you can surely connect to the network
if you want to change your routing path i can suggest you a guide which is here
http://pptpclient.sourceforge.net/routing.phtml#automatic-setupbut if you needed further assistant , don't hesitate to ask
P.P.S: this if your tunnel didn't work try it with
sudo pon $connection_name علیرضا گیر نده بهم که چرا انگلیسی جواب دادم ، زیاد بود حوصله نداشتم همش فارسی انگلیسیش کنم خودم رو راحت کردم
