VPN GATE client for linux

• Be able to connect to open vpn servers at http://www.vpngate.net/en/ directly or through proxy
• Auto add DNS to fix DNS leak.
• Auto filter out dead VPN servers. (updated on August 16th)
• Can execute user defined script after vpn_tunnel is established or broken.

Work on Debian and Redhat based system. Tested on Ubuntu, Raspbian, Fedora, Bunsen.

Forked from https://github.com/Dragon2fly/vpngate-with-proxy/

• Added auto mode
• Only cli version, removed everything else
• Moved config.ini, vpn_user_script.sh and vpn_tmp to folder where is vpnproxy_cli.py stored (You can change path by editing vars with path in vpnproxy_cli.py)
• Include config.py in vpnproxy_cli.py to make script more tiny

• python 2.7.x: should already be shipped with your linux

Except python 2.7.x, all below dependencies should be automatically installed at first run.

• openvpn: $ sudo apt-get install openvpn
• python-requests: $ sudo apt-get install python-requests

• If your network is behind a proxy

  $ export http_proxy="http://your_proxy:your_port"
  $ export https_proxy="http://your_proxy:your_port"

• If you has just installed your os, please update your os for it to fetch packages list and know where to download other packages later.

$ sudo apt-get update && sudo apt-get upgrade

• Please check the os clock and calendar if it is correct for openvpn authentication to work properly.

Just copy vpnproxy_cli.py and vpn_user_script.sh from repo and run under root.

user_script:

Within this folder, there should be a file vpn_user_script.sh. This file allow you to run extra commands to fit your need. You have to manually edit this file and don't change the file name. Commands are divided into 2 groups:

• up: execute after vpn tunnel is established successfully.
• down: execute after vpn tunnel is broken/terminated.

If you have configured system wide proxy or proxy in firefox, it'd better to turn it off. After vpn tunnel is established, the programs that use system wide proxy may failed to connect to the internet using your proxy.

Launch vpngate-with-proxy by

$ cd vpngate-with-proxy
$ ./vpnproxy_cli.py

• arg could be either none or auto or config or restore.

Then the program will first setup a configuration file config.ini by asking you for proxy if needed to connect to the Internet. After that it will show the default configuration of the program. Change any parameter to suit you and press Enter to continue. Next time launching this program, you won't see this configuration again. Either modify config.ini or check 5. Some notes

If no thing goes wrong, the vpn server's list will show up.

• Connect to a specific vpn server by typing its index number (eg: 3) and then Enter. If nothing went wrong, a successfully message show up.

  

• Your currently chosen server will be highlighted with dark blue color.

• All connected servers before the current one is show in dark red color.

• Vpn command: As you mentioned above, give an index of the server then hit Enter will open a vpn tunnel from your to that server. And there are still some more.

  • r, refresh: fetch new server's data from vpngate.net or mirrors
  • restore: will restore your system DNS back to original one
  • ctrl+c: send SIGTERM to all openvpn processes
  • q: terminate vpn tunnel, then quit the program
  • c, config to run configuration

• Auto mode

• In auto mode script automatically connects first server. If connection failed or dropped, script automatically connect to next server. Script will continue connecting to first 20 servers, then wait 60 seconds and refresh server list. You can change sort options in config.ini. Ctrl+C to connect next server, Double Ctrl+C to close script.

A successful connection doesn't mean you have access to the Internet. If you can access the Internet through selected vpn server, that doesn't mean you are totally safe.

1. Check if you can access the Internet: * try browse some websites. Low score VPN servers tend to block you out of the Internet

2. Check DNS leak:

If you are serious about privacy, this is necessary. DNS server knows the web addresses that you connected to, unless you type IP address directly.

To know your current DNS provider, https://www.dnsleaktest.com or https://ipleak.net

• Turn on DNS fix by press F3 before connecting to vpn server. Choose some good DNS from http://pcsupport.about.com/od/tipstricks/a/free-public-dns-servers.htm
• Connect to any VPN server and test if your dns provider is changed.

If DNS is not changed, make sure that you have turned off your system wide proxy and try again. While using the ethernet for vpn, connected to wifi may reset your DNS.

You could also use below command in Ubuntu to see trace route:

$ mtr -rw google.com

• To view or change settings before the program fetches server's list, use one of below:

$ ./vpnproxy_cli config

• To view or change settings at server's list: type Vpn command c or config then Enter

• Ctrl+z: Try not to press this combination while program is running. It will not terminate the vpn tunnel nor kill the program properly. Which means iptable may be left messed up, DNS won't reset to original, you may be still in vpn.

• If your terminal looks weird after program crashed or Ctrl+z, $ reset would help

If the program is unable to fetch new server data nor connect to any vpn server, your networking is not back to normal.

That is when restore, kill and log on command come in handy.

You will need to reset your network setting by:

1. kill all openvpn processes
2. $ sudo service network-manager restart

Restart your system or reconnect to wifi or ethernet will also help. If it still doesn't, your proxy may be offline or \etc\resolv.conf's content is incorrect. Ping your proxy from another computer to test. And double check \etc\resolv.conf

If your network is behind a proxy, there is a chance that your ip will be blocked. Testing if OpenVPN servers are dead or alive requires spamming many socket connection. Although the program has limited the number of socket connection per second, the proxy may think it is being DDoS. Search in the source code for test_interval and increase it a little bit.
