Linux: AirVPN Suite 1.0.0 released

Staff

Hello!

We're very glad to introduce a new software suite for Linux.

The suite includes the well known Hummingbird software, updated to the latest OpenVPN AirVPN library, and introduces for the first time a D-Bus controlled, real daemon, Bluetit, as well as a command line client, Goldcrest, to interact with Bluetit.

New architecture

The client-daemon architecture we introduce for the first time in our software offers a more robust security model and provides system administrators with a fine-grained, very flexible access control.

Bluetit is fully integrated with AirVPN. The daemon is accessed through a D-Bus interface by providing specific methods and interface in order to give full support to OpenVPN connection and AirVPN functionality, including - but not limited to - quick automatic connection to the best AirVPN server for any specific location as well as any AirVPN server or country. Connection during system bootstrap is fully supported as well.

New OpenVPN 3 library features

Hummingbird and Bluetit are linked against a new version of our OpenVPN 3 library which supports directive data-ciphers: it can be used consistently with OpenVPN 2.5 syntax in OpenVPN profiles.

The directive allows OpenVPN 3 based software to negotiate a common Data Channel cipher with the OpenVPN server,, updating therefore our library to ncp-like negotiation with OpenVPN 2 branch. Hummingbird and Bluetit are already linked against the new library version, while Eddie Android edition will be updated in the near future.

The new library also includes a different handling of IV_CIPHERS variable, fixing OpenVPN main branch issues which caused a plethora of problems with OpenVPN 2.5. The implementation, at the same time, takes care of full backward compatibility with OpenVPN versions older than 2.5.

ncp-disable directive, which to date has never been implemented in the main branch, is still supported, in order to further enhance backward compatibility with both OpenVPN profiles and servers, as well as connection flexibility with servers running older than 2.5 OpenVPN versions.

Please note that if you enforce a specific Data Channel cipher by means of Bluetit configuration file, Hummingbird line option, or Goldcrest configuration file and/or line option, the enforced Data Channel cipher will override data-ciphers profile directive.

Changelog 3.6.6 AirVPN by ProMIND

- [ProMIND] [2020/11/02] openvpn/ssl/proto.hpp: IV_CIPHERS is set to the overridden cipher only
                         (both from client and/or OpenVPN profile) in order to properly work
                         with OpenVPN 2.5 IV_CIPHERS specifications. The old method of cipher
                         overriding by means of negotiable crypto parameters is still supported
                         in order to maintain compatibility with OpenVPN < 2.5.0
- [ProMIND] [2020/11/24] added "data-ciphers" directive to profile config .ovpn files in order
                         to comply to OpenVPN 2.5 negotiable data cipher specifications. In case
                         "data-ciphers" is found in the .ovpn files IV_CIPHERS is assigned to the
                         algorithms found in "data-ciphers". In this specific case, "cipher"
                         directive is used as a fallback cipher and, if not already specified in
                         "data-ciphers", is appended to IV_CIPHERS

Notes on systemd-resolved

In Fedora 33 systemd-resolved comes pre-configured to work in "on-link" mode and network-manager works together with it.

This very peculiar, Windows-like setup kills Linux global DNS handling, causing those DNS leaks which previously occurred only on Windows. Hummingbird and Bluetit take care of preventing the brand new DNS leaks caused by such a setup.

Also note that systemd-resolved comes pre-configured with fallback DNS (Google DNS is a systemd-resolved default fallback DNS, smart choices pile up!) which will be queried if each interface DNS server fails some resolution. In such a case, if and only if you have Network Lock enabled will DNS leaks be prevented.

Supported systems

The suite is currently available for Linux x86-64, i686 (32 bit distributions), arm7l (for example Raspbian and other ARM 32 bit based systems) and aarch64 (ARM 64 bit).

AirVPN Suite is free and open source software licensed under GPLv3.

Overview and main features

AirVPN’s free and open source OpenVPN 3 suite based on AirVPN’s OpenVPN 3 library fork
Version 1.0.0 - Relase date 7 January 2021
Bluetit: lightweight D-Bus controlled system daemon providing full connectivity to AirVPN servers and generic OpenVPN servers. Ability to connect the system to AirVPN during the bootstrap.
Goldcrest: Bluetit client, allowing full integration with AirVPN servers, users, keys, profiles as well as generic OpenVPN servers
Hummingbird: lightweight and standalone client for generic OpenVPN server connection
Linux i686, x86-64, arm7l and arm64 (Raspberry) support
Full integration with systemd, SysVStyle-init and chkconfig

@6gh54F4

Hello and thank you for your choice!

In order to have the suite properly run, you need to install and configure the whole D-Bus infrastructure

The error message "ERROR: D-Bus is not properly configured or not available " is caused by the fact that D-Bus is not properly configured or installed. If it's not installed, please install it.

If it's installed, please make sure that it's active and running:

sudo systemctl enable dbus.service
sudo systemctl start dbus.service

https://wiki.archlinux.org/index.php/D-Bus

If D-Bus is already running but the problem persists, please re-contact us.

Kind regards

6gh54F4

Ok so it says D-Bus is ACTIVE (running) ...but it has error msgs:

Jan 15 08:03:14 desktop dbus-daemon[485]: [system] Activation via systemd failed for unit 'dbus-org.freedesktop.home1.service': Unit dbus-org.freedesktop.home1.service n>

If I run $ sudo systemctl enable dbus.service:

"The unit files have no installation config (WantedBy=, RequiredBy=, Also=,

Alias= settings in the [Install] section, and DefaultInstance= for template

units). This means they are not meant to be enabled using systemctl."

airvpnclient

Cool! Works perfectly on OSMC media box for Rpi.

I see there is now a declaration in the bluetit run control file to bring up the vpn, firewall, dns on boot. Yay!

With hummingbird, I had recently encountered a problem that --recover-network options would not solve. Apparently it did something NOT GOOD that persisted, so I thought I'd check on the status of the AirVPN Suite just in time to test 1.0 (beta).

Installing the Suite was a breeze following the excellent documentation on GitLab (not GitHub, thank you very much).

It brought the server to a secure state on boot as required. Great work. In the interest of the project, here is some data:

@airvpnclient

Hello!

Thank you for your feedback, we're very pleased to read it.

However, we have found a problem in you log, unfortunately:

Jan 14 21:13:57 osmc bluetit[940]: ERROR: Cannot activate network filter and lock

We would like to investigate. Can you please give us your system iptables version?

Kind regards

Hello!

Let us try under OSMC latest release and reproduce the issue. In the meantime please open a ticket and, if you don't mind, send us your account password (in the ticket - you can then change it even immediately after you have sent it to us) as well as your bluetit.rc file.

About communications with Bluetit, default policy allows any user in group airvpn so you should not run Golcdrest with root privileges, just run it from any user in airvpn group.

Normally login failure at boot would not be a problem because Network Lock would be enforced anyway, but in this case we saw issues with Network Lock too. Did you disable Network Lock in bluetit.rc ?

We will keep you posted both here and in the ticket system.

Kind regards

airvpnclient

K. Happy to help smooth out these bumps. This is the latest OSMC with apt full-upgrade run. Watch for the ticket.

Is it possible to make use of OpenVPN over SSL in goldcrest directly? If not, is integrating stunnel into goldcrest (and firecrest, once it's released) a planned feature?
I couldn't find any reference for establishing such a connection in the user documentation, udp & tcp seem to be the only options.

Downloading .ssl and .ovpn files for specific servers and starting the stunnel process manually seems rather clunky.
I really prefer how the Eddie client allows for SSL connections to any arbitrary AirVPN server by simply choosing said protocol in the settings.

Probably a scam, then

"AirVPN Staff will never ask you for your password."

The "IPv6 is not available in your system" error is back. Cannot use v6 to connect to AirVPN again. air-ipv6, air-6to4 and ipv6 rc options all set to on, tried setting them to off and no via arguments but journalctl prints that bluetit still uses air-ipv6 (V) -> on.

No offense, but this is getting a little ridiculous now.

Hello!

When Bluetit starts, it asks the kernel whether the IPv6 layer is available. Furthermore, Bluetit asks systemd to be run only after the network layer is up. If systemd launches Bluetit when IPv4 layer is up but IPv6 layer is not, Bluetit correctly is started by systemd and informed by the kernel that IPv6 is not available, and will not use it during its entire run life.

It is important not to rely on IPv6 when the kernel tells that it's not available, otherwise OpenVPN3 library will throw various, critical errors.

You first experienced this "problem", then you reported that it was resolved, then you again report that you experience the problem, but Bluetit code in that part has never changed between beta1 and final release, so what is ridiculous here? We can't understand your hostile attitude.

It comes to mind that the inconsistent behavior you report is due to the fact that Bluetit is run by systemd before the IPv6 layer is available, while when you did not detect the problem the IPv6 layer had already come up when Bluetit was started. Please check: if you find that starting Bluetit manually when the IPv6 layer is surely up does not cause the problem, then you have a confirmation of the above. Let us know.

That seems correct and expected, as Goldcrest can't bypass bluetit.rc settings, by design based on very good reasons.

@Acteon

Hello!

It's not planned at the moment. OpenVPN over an additional SSL/TLS tunnel is nowadays made obsolete by tls-crypt. Same block circumvention abilities, much higher performance.

NOTE: you can have Eddie run Hummingbird if you wish to use OpenVPN 3 AirVPN library while at the same time you want the ability to add an additional TLS tunnel by stunnel. Make sure to run Eddie 2.19.7 or higher version (older versions can't invoke Hummingbird 1.1.1 properly).

Kind regards

Staff

@airvpnclient

Thanks! Ticket received and the matter is under investigation. We will update this thread too when we find anything relevant, for all readers.

Kind regards

OpenSourcerer

Bluetit is not started with the system. It's started manually when needed, when IPv6 is unquestionably available.

I stopped bluetit and started it again 30 minutes later. Error is gone.
I'm done. No idea how to troubleshoot this.

Staff

@OpenSourcerer

Hello!

Probably the kernel tells Bluetit that IPv6 layer is not available when you see the "problem". It's not enough that IPv6 is available locally in the system, of course (that's a pre-requisite only to tunnel IPv6 over IPv4). Can you give us the list and properties of all physical interfaces just before you start Bluetit with the "problem" and the exact distribution which you have this inconsistent behavior on?

Kind regards

X cut for privacy, as usual. This is when it works, to make a comparison possible.

Will post another when I see the error popping up again. Unless you want output from another program.

@OpenSourcerer

Hello!

The output is fine. We'll be waiting for the next one to compare. What is the exact distribution?

Kind regards

OK.

Ideally take the output just before you run Bluetit, then, if the problem occurs, save that output.

Hello and thank you for your choice!

In order to have the suite properly run, you need to install and configure the whole D-Bus infrastructure

The error message "ERROR: D-Bus is not properly configured or not available " is caused by the fact that D-Bus is not properly configured or installed. If it's not installed, please install it.

If it's installed, please make sure that it's active and running:
sudo systemctl enable dbus.service
sudo systemctl start dbus.service
https://wiki.archlinux.org/index.php/D-Bus

If D-Bus is already running but the problem persists, please re-contact us.

Kind regards

I'm also trying to install AirVpn suite and I'm getting this same error. I can confirm that I have dbus running, but the installer says "ERROR: D-Bus is not properly configured or not available". What should I configure?

Staff

@6gh54F4
@suroh

Hello!

Can you please send us the installed D-Bus related packages in your system? Can you tell us whether, in your system:
/etc/dbus-1
/etc/dbus-1/system.d
/usr/share/dbus-1/system.d

exist or not?

@suroh, can you please specify your distribution too?

Kind regards

suroh

I am running Arch Linux, uname spits out `5.10.8-arch1-1`
I only have `/usr/share/dbus-1/system.d`

Staff

@suroh

Hello!

OK, please hold on, we will release a fixed installation script very soon.

If you want to edit install.sh for a dirty hot fix (let us know if it works):

1) Find the line:

if [ ! -d "/etc/dbus-1" ] || [ ! -d "/etc/dbus-1/system.d" ]; then

and replace it with

if [ ! -d "/etc/dbus-1/system.d" ] && [ ! -d "/usr/share/dbus-1/system.d" ]; then

2)

Find the lines:

cp etc/dbus-1/system.d/* /etc/dbus-1/system.d
chmod 644 /etc/dbus-1/system.d/org.airvpn.*

and replace them both with the following block of text:

if [ -d "/etc/dbus-1/system.d" ]; then
   cp etc/dbus-1/system.d/* /etc/dbus-1/system.d
   chmod 644 /etc/dbus-1/system.d/org.airvpn.*
fi

if [ -d "/usr/share/dbus-1/system.d" ]; then
   cp etc/dbus-1/system.d/* /usr/share/dbus-1/system.d
   chmod 644 /usr/share/dbus-1/system.d/org.airvpn.*
fi

Please note that the uninstall script will also have to be adapted (the fix will include a new uninstall.sh).

Kind regards
