Package: nordvpn-switcher
New version: 0.3.0(11/06/2022)Updates for version 0.3.0:IP check - regex fix: website used for IP check has changed; old regex pattern is unable to capture new IP.Spelling error: 'Salk Late City' connection option has been changed to 'Salt Lake City'.Updates for version 0.2.9:Fix in nordvpn account check: only relevant if you'd like to login through NordVPN switcherUpdates for version 0.2.8:Fixed ip check bug: script was unable to detect current ip due to an SSL cert. error. on ident.me. To remedy this, the list of websites used for the ip check has been updated. This should fix most of the connection error issues.Changes in login procedure in newer NordVPN app versions (for Linux users only): Login command has been altered for newer NordVPN app versions.Updates for version 0.2.7:Fixed quick connect bug: the script got stuck in an infinite loop if the quick-connect option was chosen using the area_input parameter.Updates for version 0.2.6:Fixed ip leakage issue: to avoid ip leakage (e.g. while scraping), the script saves your original ip when using the initialize_VPN() function in the instructions dict/file. After rotation and thus when using the rotate_VPN() function, it checks whether your new ip is different from not only the previous ip,but alsoyour original ip.Updates for version 0.2.5:Added a 'complete rotation' functionality: allows you to rotate between the 4000+ available servers at random. This is different from connecting to a specific region (e.g. country, state), since NordVPN automatically opts for the 'best' server in that particular area. This means you're often connecting to the same small subset of fast servers. When the 'complete rotation' parameter is set to 1, server rotation is truly random. This is a neat function for webscraping purposes.Added a 'skip settings' functionality (for Linux users only): Linux users are asked whether they'd like to execute additional settings (such as whitelisting ports) whenever they run the initialize_VPN() function. When the skip_settings parameter is set to 1, nordvpn-switcher will assume the user does not wish to execute additional settings. When the user combines this with the area_input parameter, it is possible to run NordVPN switcher right from the get-go without any required user-input on Linux (see demo.py for example code).The script uses the fake_useragent packagefor improved header-inputAdded an additional pause to slow the script down on Windows.Some users - especially if they run the NordVPN app on slow machines - are unable to rotate between servers because the app takes a while to start up.Added more example codein the demo.py file (see files on Github)To all of those who've sent me feedback and/or reported bugs: thank you!NordVPN-switcherRotate between different NordVPN servers with ease. Works both on Linux and Windows without any required changes to your code.pip install nordvpn-switcherand you're all set!Created by Kristof BogheBut...why?I realize there are multiple NordVPN-related packages available, but they only work for Linux and/or are not exactly user-friendly.NordVPN-switcher is:1. Able to run both on Windows and LinuxYou don't need to perform any changes to your script. NordVPN-switcher automatically detects your OS and executes the appropriate code automatically.
This means you're able to share your code with your colleagues without having to worry about the OS they use.2. User-friendlyNordVPN-switcher includes a step-by-step menu that takes you through the entire setup. You don't need to construct some chaotic .txt files; you don't even need to know how to run a terminal/cmd command at all!Before attempting any VPN connection, it performs a system-checkup and checks whether the NordVPN app is installed, running and whether you are logged in.If you're not logged in and you're on Linux, you can log in through the Python terminal with easeIf you're on Linux, it's possible to run whatever additional setting through the NordVPN app (such as setting the killswitch value, whitelisting ports, etc.). You can replicate these settings every time you run your script with ease by saving these commands into a JSON-file (simply by setting thesaveparameter to 1).On Windows, it checks multiple installation directories for the NordVPN app. When the script is unable to locate the installation folder, the menu will ask you for the folder location. The script is able to save this installation folder so you'll never have to worry about it again.It even includes a spelling checker (So any attempt to connect to - let's say - "Flance" won't cause any trouble)A dictionary of world regions (e.g. Europe) and local regions (e.g. Cities in the US) is included as well. Especially on windows, taking a random pick within a wider region (e.g. asia pacific) is a real drag. NordVPN-switcher handles these kind of random-pick use-cases with ease.3. ForgivingWe all like to run our script and ignore it for the next couple of days without worrying about random connectivity hiccups. NordVPN-switcher retries and connects to a different server when it is unable to fetch your new ip.If requested, it also switches servers when Google and/or Youtube throws a captcha (see further).4. Able to check for captcha's on Google and/or YouTubeEspecially on busy servers, captcha checks can disrupt your webscraper (e.g. when scraping Google) or overall browsing experience. If requested (by setting thegoogle_checkparameter to 1), captcha-checks are performed after each server rotation. If a captcha pops up, the script will automatically try a new server.5. FlexibleYou can ask NordVPN-switcher to hold your hand or go rogue and feed it your own settings-file in JSON-format. if a collaborator wants to share his or her unique settings, he or she can simply send you its settings-file and that's about it!InstallMake sure NordVPN is installed.On Linux, run:wget -qnc https://repo.nordvpn.com/deb/nordvpn/debian/pool/main/nordvpn-release_1.0.0_all.deb
sudo dpkg -i /pathToFile/nordvpn-release_1.0.0_all.deb #replace pathToFile to location download folder
sudo apt update 
sudo apt install nordvpn(From the NordVPN FAQ)On WindowsDownload the app here -->https://bit.ly/3ig2lU5Install the packageExecute in terminal:pip install nordvpn-switcherOR, for the ones who don't use pip for some reason:Download/clone this repositoryRunpip install -r requirements.txtto install dependenciesImport functions`from nordvpn_switcher import initialize_VPN,rotate_VPN,terminate_VPNRotate between servers, for example:import time 

initialize_VPN(save=1,area_input=['complete rotation'])

for i in range(3):
    rotate_VPN()
    print('\nDo whatever you want here (e.g.scraping). Pausing for 10 seconds...\n')
    time.sleep(10)will perform a truly random rotation between all available NordVPN servers.That's it!The building blocksIn essence, you'll just use the following three functions:1. Setting up your NordVPN settingssave: if you want to save these settings for laterstored_settings: if you want to execute particular settings already saved in your project folderarea_input: if you want to feed a list of connection options (not necessary). Useful when you want to automate the formulation of a server list (see option 5 in the 'some features and options' section). If you want to rotate truly at random between the 4000+ available NordVPN servers, just set this parameter to['complete rotation']. If you'd like to rotate between 10 random European countries, set this parameter to['random countries europe 10']etc. See the demo.py file for more examples.skip_settings: only relevant for Linux users, since they are able to execute additional settings. Set this parameter to 1 if you'd like to skip the settings-input. If Linux users combine the this with an area_input, they simply skip entire the step-by-step menu initiated by the initalize_VPN() function.initialize_VPN(stored_settings=0,save=0,area_input=None,skip_settings=None)2. Rotating between servers.instructions: the instructions saved from the initialize_VPN function. If none is provided, the script looks for a nordvpn_settings.txt file in your project folder (which you can create by setting thesaveparameter in the first function to 1).google_check: if you want to perform a google and Youtube captcha-checkrotate_VPN(instructions=None,google_check = 0)3. Disconnecting from the VPN serviceExecute this function at the end of your script (not (!) while you're hopping from server to server in a loop)terminate_VPN(instructions=None)How to use--> Please check out the demo.py file on GitHub (https://github.com/kboghe/NordVPN-switcher/) for more examples <--Option 1: save settings in environmentThe easiest and most user-friendly (although least automated) way of using NordVPN switcher is by saving the instructions into a new variable and feeding it to the rotate_VPN() function.from nordvpn_switcher import initialize_VPN,rotate_VPN,terminate_VPN

settings = initialize_VPN() 
rotate_VPN(settings) 
rotate_VPN(settings,google_check=1) 
terminate_VPN(settings)In practice, you'll usually execute the rotate_VPN() function within some kind of loop.settings = initialize_VPN() #initialize VPN and save settings variable
for i in range(3): (e.g. you'd like to loop over 10.000 urls)
    rotate_VPN(settings)
    *perform some other code, e.g. scraping*
    rotate_VPN(settings,google_check=1) #with google and youtube captcha check

terminate_VPN(settings)if you want to rotate between servers in an infinite loop, you can use the while true statement:while True: 
    rotate_VPN(settings)
    time.sleep(3600) #e.g. rotate servers every hourThanks to the area_input parameter and the 'complete rotation' functionality, you don't have to provide any input at all. NordVPN will simply hop from server to server in a truly random fashion.initialize_VPN(save=1,area_input=['complete rotation'])

for i in range(3):
    rotate_VPN()
    *perform some other code, e.g. scraping*

terminate_VPN()Option 2: save settings and execute on each runIf you want to make sure that certain NordVPN setting commands are executed (e.g. killswitch, whitelisting ports, etc.) on each run, save the instructions into your project folder once by setting thesaveparameter to 1 and execute theinitialize_VPNandrotate_VPNfunction every time you run the script. NordVPN-switcher will alert you what kind of additional settings are pulled from the settings-file.#do this once
initialize_VPN(save=1)Ifsave=1, the script will write a .txt file in JSON format to your project folder. It contains all the necessary information needed to execute therotate_VPNfunction. Again, when the instructions parameter is missing inrotate_VPN, it will automatically look for the settings file in your project folder.--On Windows, the contents of the nordvpn_settings.txt file look something like this (random example):`{'opsys': 'Windows', 'command': ['nordvpn', '-c', '-g'], 'settings': ['belgium', 'netherlands', 'germany', 'spain', 'france'],  'original_ip': '82.169.108.182', 'cwd_path': 'C:/Program Files/NordVPN'}-- On Linux, the file looks slightly different (different random example):{'opsys': 'Linux','original_ip': '82.169.108.182','command': ['nordvpn', 'c'], 'settings': ['United_States', 'Canada', 'Brazil', 'Argentina', 'Mexico', 'Chile', 'Costa_Rica', 'Australia'], 'additional_settings': [['nordvpn', 'set', 'killswitch', 'disable'], ['nordvpn', 'whitelist', 'add', 'port', '23']],'credentials':[['name@gmail.com'],['coolpassword]]}Thanks to the saved .txt file, you never need to go through the menu options ofinitialize_VPN()again. So, some time later, you simply perform:initialize_VPN(stored_settings=1)
rotate_VPN()
#do stuff
terminate_VPN()This option is only relevant for Linux users who wish to execute additional settings such as enabling killswitch etc. Executing these additional settings is not an available option on Windows machines.Option 3: save settings and just use rotate on each runThis is similar to option 2, but without executing theinitialize_VPNfunction on each run.
This is relevant for all Windows machines or Linux machines who do not wish to execute additional settings.#do this once
initialize_VPN(save=1)

#open project on a later date and just use the following two lines of code:
rotate_VPN()
#do stuff
terminate_VPN()Option 4: manual optionCreate or obtain your own settings_nordvpn.txt file, place it in your project folder and use the rotate function#
For example, share particular settings with colleagues/friends who work on the same project by sending them your .txt settings file. Place it in your project folder and just use therotate_VPNfunction.rotate_VPN()
#do stuff
terminate_VPN()> See the demo.py file for a summarySome features and options1. Rotate between all available NordVPN servers at random.This differs from any other connection method since NordVPN automatically picks the most 'appropriate' (as in fastest) server in a particular region. This means that connecting to, let's say, the Netherlands means you'll often end up with the same server time and time again. The 'complete rotation' functionality allows you to completely randomize server selection.initialize_VPN(area_input=['complete rotation'])
rotate_VPN()
#do stuff
terminate_VPN()2. Provide additional settings and save these for later use, if so desired (only on Linux)3. Login to NordVPN if logged out (only on Linux)4. Take a random sample from a larger region5.Spellchecker6. Provide a list of connection options, which will be automatically incorporated into the nordvpn_settings.txt filerange_servers = range(800,837)
server_list = ["nl"+str(number) for number in range_servers]
instructions = initialize_VPN(area_input = server_list)
rotate_VPN(instructions)6. NordVPN app starts automatically (if closed) on Windows. Connection process can also be monitored by checking the NordVPN appWindows vs LinuxThe script runs slower on Windows. This can be explained by the fact that the script communicates directly with NordVPN.exe, which means it inherits the poor speed performance of the Windows app by definition. Compare the speed of the previous gifs (all executed on a Linux machine) with the following gif, executed on Windows:Linux users have a couple of additional options at their disposal, namely:1.Being able to log in through the Python interface. Windows users need to make sure they're already logged into the NordVPN app. The Windows app remembers your log in by default though, so this shouldn't cause too much trouble. So even when the app is closed, NordVPN-switcher should work.2.Executing additional settings (e.g. killswitch etc.)Settings files can't be directly shared between Windows and Linux machines (see option 4 - how to use). Of course, with a little tweaking, separate Windows and Linux settings-files can easily be constructed for your specific project.Possible applicationsTo circumvent ip-blocks from certain websites (e.g. while scraping particular platforms)In this case, the VPN switcher basically serves the same function as the often-used proxy lists while scraping the web (e.g. with BeauitfulSoup), but without the common disadvantages associated with the latter.To automate a particular task that benefits from being performed by many ip-addressesFor security reasonsI'm pretty sure there are plenty of other viable applications out there. NordVPN-switcher is extremely easy to implement, no matter the particular problem/project at hand.Questions, problems, nasty bugs to report?kboghe@gmail.comHave fun!
