AirVPN client based on OpenVPN 3.3 AirVPN

Recommended Posts

Hello!

We are very glad to introduce a new client software for Linux 64 bit and Linux Raspbian 32 bit (which is frequently installed in Raspberry PI), based on our own AirVPN OpenVPN 3 library.

The software is an initial and temporary step toward a more refined product to meet right now various demands by many Linux and *BSD users. It does not have a code name yet, and it is just "AirVPN OpenVPN 3 client" at the moment. It will evolve in to an integrated client and daemon targeting Linux, Mac, OpenBSD and FreeBSD platforms.

Main features:

  • lightweight and stand alone binary
  • no heavy framework required, no GUI
  • tiny RAM footprint (less than 3 MB currently)
  • lightning fast
  • based on OpenVPN 3 library fork by AirVPN with tons of critical bug fixes from the main branch, new ciphers support and never seen before features
  • ChaCha20-Poly1305 cipher support on both Control and Data Channel providing great performance boost on Raspberry PI and any Linux-based platform not supporting AES-NI
  • robust leaks prevention through Network Lock based either on iptables or nftables through automatic detection
  • proper handling of DNS push by VPN servers, working with resolv.conf as well as any operational mode of systemd-resolved
  • additional features

Versions for Mac, FreeBSD and OpenBSD will follow in the near future.

The software is currently in alpha stage and it must be therefore and implicitly considered unstable and under development. Source code will be made public at the release of a stable version. If you wish to test, feel free to download the binaries here and report in this very thread any bug, glitch and anything you wish:

Linux 64 bit version: https://eddie.website/repository/eddie/airvpn-static1.0alpha/airvpn-static-linux-1.0-alpha2.tar.gz

Raspbian 32 bit version: https://eddie.website/repository/eddie/airvpn-static1.0alpha/airvpn-static-raspberry-1.0-alpha2.tar.gz
 

How to install AirVPN client for Linux x86_64 and Raspberry

Requirements
------------


Linux
  • x86-64 CPU/architecture
  • A reasonably recent 64 bit Linux distribution
  • tar
  • sha512sum (optional)

Raspberry
  • Linux Raspbian distribution
  • tar
  • sha512sum (optional)
 

Linux Installation
------------------

  • Download airvpn-static-linux-1.0-alpha2.tar.gz
  • [optional] Download airvpn-static-linux-1.0-alpha2.tar.gz.sha512 This file is required to check the integrity of the above tar archive. It is not mandatory but it is strongly advised to download this file and check the tar archive
  • [optional] Open a terminal window
  • [optional] Check the integrity of the tar archive by issuing this command: "sha512sum --check airvpn-static-linux-1.0-alpha.tar.gz.sha512" (without quotes)
  • [optional] Make sure the command responds with "airvpn-static-linux-1.0-alpha.tar.gz: OK"
  • Change your current directory to a convenient place, such as your home directory. This can be done by issuing the command "cd ~" (without quotes)
  • Extract the tart archive by issuing this command on your terminal window: tar xvf airvpn-static-linux-1.0-alpha.tar.gz
  • The process will create a directory airvpn-static-linux-x86_64
  • Issue the "cd airvpn-static-linux-x86_64" (without quotes)
  • [optional] Check the integrity of the binary file airvpn. Issue this command from your terminal window: sha512sum --check airvpn.sha512" (without quotes)
  • [optional] Make sure the command responds with "airvpn: OK"
  • [optional] Check dynamic library availability. Issue the command "ldd airvpn" and make sure all the required dynamic libraries are available. No line of the output must contain "not found"
  • the Linux client is now ready to be used and possibly copied to a different directory of your system.
  • Please note the client needs root privileges. Your user must therefore be included in your system's "sudoers" (depending on specific Linux distribution)
 

Raspberry/Raspbian Installation
-------------------------------

 
  • Download airvpn-static-raspberry-1.0-alpha2.tar.gz
  • [optional] Download airvpn-static-raspberry-1.0-alpha2.tar.gz.sha512 This file is required to check the integrity of the above tar archive. It is not mandatory but it is strongly advised to download this file and check the tar archive

  • The process will create a directory airvpn-static-raspberry
  • Issue the "cd airvpn-static-raspberry" (without quotes)
  • [optional] Check the integrity of the binary file airvpn. Issue this command from your terminal window: sha512sum --check airvpn.sha512" (without quotes)
  • [optional] Make sure the command responds with "airvpn: OK"
  • [optional] Check dynamic library availability. Issue the command "ldd airvpn" and make sure all the required dynamic libraries are available. No line of the output must contain "not found"
  • the Raspberry/Raspbian client is now ready to be used and possibly copied to a different directory of your system.
  • Please note the client needs root privileges. Your user must therefore be included in your system's "sudoers"
 

Running the Client
------------------


Run the client and display its help and become familiar with its options. From your terminal window issue this command:

 
sudo ./airvpn --help

After having entered root password, the client responds with:

The client needs a valid OpenVPN profile in order to connect to a server. You can create an OpenVPN profile by using the config generator available at airvpn website in your account "Client Area"

To start a connection:

   
sudo ./airvpn your_openvpn_file.ovpn

To stop a connection, just type CTRL+C. The client will initiate the disconnection process and will restore your original network settings according to your options.


To start a connection with a specific cipher:

   
 sudo ./airvpn --ncp-disable --cipher CHACHA20-POLY1305 your_openvpn_file.ovpn

Please note, in order to properly work, the server you are connecting to must support the cipher specified with the "--cipher" option. If you wish to use CHACHA20-POLY1305 cipher, you can find AirVPN servers supporting it in our real time servers monitor https://airvpn.org/status : they are marked in yellow as "Experimental ChaCha20".

To disable the network filter and lock:
sudo ./airvpn --network-lock off your_openvpn_file.ovpn

To ignore the DNS servers pushed by the VPN server:
 
sudo ./airvpn --ignore-dns-push your_openvpn_file.ovpn

Please note: the above options can be combined together according to their use and function.

 

Note on network filter and lock
-------------------------------


The client's network filter and lock uses natively iptables and nftables. The client will automatically use the infrastructure available on your system. Please note: services firewalld and ufw may interfere with the client's network filter and lock and you are strongly advised to not issue any firewall related command while the VPN connection is active.
 

Note on DNS
-----------


The client currently supports both resolv.conf and systemd-resolved service. When the client is running you are strongly advised to not issue any resolved related command (such as resolvectl) or change the resolv.conf file in order to make sure the system properly uses DNS pushed by the VPN server. Please note: DNS system settings are not changed in case the client has been started with "--ignore-dns-push". In this specific case, the connection will use your system's DNS.


Recover your network settings
-----------------------------


The client is currently in alpha stage and it must be therefore and implicitly considered unstable and under development. In case the client crashes or it is killed by the user (i.e. kill -9 `pidof airvpn`) as well as in case of system reboot while the connection is active, the system will keep and use all the network settings determined by the client; hence, your network connection will not work as expected, every connection is refused and the system will seem to be "network locked". To restore and recover your system network, you can use the client with the "--recover-network" option
 
sudo ./airvpn --recover-network


Please note in case of crash or unexpected exit, when you subsequently run the client it will warn you about the unexpected exit and will require you to run it again with the "--recover-network" option. It will also refuse to start any connection until the network has been properly restored and recovered.


Kind regards and datalove

Four simple things:
There's a guide to AirVPN. Before you ask questions, take 30 minutes of your time to go through it.

Amazon IPs are not dangerous here. It's the fallback DNS.
Running TOR exits is discouraged. They're subject to restrictions on the internet and harm all AirVPN users.

Furthermore, I propose that your paranoia is to be destroyed. If you overdo privacy, you'll be unique among the mass again.

Hello!

Thanks! We can guess the bug from the log, yes, in the attempt to resolve IPv6 addresses instead of names which produce those warnings and in the end a fatal error. Can you please send us your profile (without certificates and keys, of course) for additional investigation?

Kind regards

Hello!

If you have time to make comparisons, please take note whether OpenVPN 2, on rigorously equal terms (therefore no ChaCha20 comparison is possible unless you run OpenVPN 2.5 beta), is faster or slower than 3.3, and feel free to publish the throughput you get with both versions.

Kind regards

I suspect that the server I had yesterday was very busy and therefore slightly less fast.
How I can make the comparison, that's too high for me sorry.

Linux is a hobby, and I don't work in IT😉

Lo lo Great great, at last something sweeter than wheezing monogenetic hyperbugged psychowindowsish mammoth Eddie. Aaaaand... fixing for real ovpn3 serious bugs, bravo AirVPN, don't wait lazy ovpn3 devs --- did not sanitize from bugs for years literally as far as I remember.

Working smoothly on Fedora 29 and Raspberry PI Raspbian in IPv4. ChaCha20 is a magic blue pill for Rasp ARM as expected, I get +20% min vs AES-128 and 256. I'm not sure I share your decision to allow momentarily local DNS traffic with Network Lock to resolve profile names. Mumbling mumbling.

Can we expect an OpenBSD version b4 xxxMas? Will u support pf and ipfw for NLock? Is this something you'll build a new g interface on top? If you build a g interface, will you make the whole forked library available in a daemon/service? Will you add user control on socket buffer or ovpn3 can manage it just fine through asio or whatever?

Will report bugs if I drive em out.

Keep it up my privacy paladins!

It worked for me straight away, using the same config file I was using in /etc/openvpn. I'm running a PI4 headless and using it as a wireless AP.
Speeds were instantly twice what I've ever had though Air prior.

Upon shutting the connection the network lock comes in as stated in the above post, and I've been forced to power off and on again. The --network-recover gives an error that no backup of resolv.conf is present, I've tried both as a command and within the config file.

I've also no internet on the AP, I can connect and get an IP address but no throughput. Eddie had an option for local traffic so maybe I'm missing that?

i have being trying to connect AIRVPN on RDP and it wouldn't work. The RDP allows AIRVPN but it won't just work, it doesn't test on your site when i run the TCP check. Pls what can i do to get this fixed and get working, it's days already. I appreciate your inputs. Thanks

That is great news, thank you, keep up the good work.

I performed a small benchmark for fun, comparing the throughput in a VM. What is weird is the Tx/Rx "reversal" with OpenVPN 2.4.4 versus 3.3.2 but probably just the peak values are relevant.

~30% more performance is something. Expected a little more but the CPU is heavily throttled (and supports AES-NI), so I guess this is a very good result. Here is the test.

Hello!


@giganerd

Bug detected and fixed, a new testing version is almost ready to be deployed. Thanks!


@QueenSasha

Thank you, actually speed, efficiency and low RAM footprint have been a priority in OpenVPN 3.3 AirVPN design. Glad to hear that you get remarkable performance boost in Raspberry. Our OpenVPN 3 development goes on and is aimed as usual to bug fixing and new features implementation.

Developer will answer soon to your technical questions, in the meantime feel free to keep us posted if you find any glitch or bug.


@usr32

Great comparison thank you! We are surprised that you could beat AES with ChaCha20 in an AES-NI supporting machine. Can you please specify the whole architecture? We would like to make some verifications with OpenVPN 3+mbedTLS for AES-NI support in specific archs.


@GJElde

So you made an OpenVPN text configuration file +x and you tried to run it? :D


@maxandjim

Thank you, we will investigate asap.


Kind regards

In the Client Area I created an .ovpn via OpenVPN Config Generator with the choice of Belgium or a country other than the Netherlands
They all don't work, only the Netherlands.

Hello!

ovpn profiles are not scripts or binaries that you can run: they are text files that will be parsed by some OpenVPN binary. Use profiles as arguments of the client software as you always did. Let's end it here and now, please: if you need clarifications on that, please feel free to open a ticket at your convenience because it's off topic here.

Kind regards

Trying a clean Raspian install on a Pi4 and noticed typos in the instructions.

Files are named alpha and the shell commands are alfa.

Did a clean install and fully updated. Buster on a headless Pi4 and set up my wifi AP with this https://www.raspberrypi.org/documentation/configuration/wireless/access-point.md#internet-sharing

Installed the Alpha1 and tried various config files and all seem to work and connect seamlessly, good speeds.
Nothing works on the AP though through the VPN, I can connect and ping wlan0 and tun0 from windows but no internet. This is probably blatantly obvious to most but I'm sadly out of my depth here so I'll leave this thread to the pros.

--recover-network gives the same fault as I mentioned earlier, no backup of resolv.conf, though when killing the connection with ctrl/c the last thing it says is "successfully restored DNS"

Ctrl/C kills everything, kills the ssh shell and I can't ssh back in to either eth0 or wlan0 #poweroff

Good luck with the project, I will keep my eye on it :-)

Bug report to check:

the software freezes when it runs with a profile containing a remote line with a name resolving to multiple addresses . After a forced kill, software doesn't restore fw rules correctly with --recover-network when launched again

Test for example with:
remote europe.all.vpn.airdns.org 443

Am I correct in understanding that, as of now, this client is not open-source since the code is nowhere to be found?


Hello!

Of course you are correct. We plan to release the stable edition of the software (or maybe the beta version) on GPLv3. We are at alpha stage currently, as you may have noticed. However OpenVPN 3 AirVPN code is available, have you examined it? Here it is: https://github.com/AirVPN/openvpn3-airvpn

Thank you, we will investigate about communications in the local network. If for some reason the remote ssh session gets broken with CTRL-C you can consider to run the client inside a screen and send a soft kill signal when you want to shut it down gracefully. Warning: if you lose ssh connection, the client will continue to run in "its screen", completely detached (even its stdin, stdout and stderr will be detached from the previous shell) so the machine will remain connected to the VPN and "network locked": make sure you can remotely force a machine reboot as an emergency rescue just in case you can't access it anymore via ssh.
