@OpenSourcerer Hello! The output is fine. We'll be waiting for the next one to compare. What is the exact distribution? Kind regards

@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

@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

@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

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. Kind regards

@Debsin Hello and thank you for your choice! In AirVPN we have a specific setup for IPv6 push aimed at maintaining compatibility with older OpenVPN versions which had a heavily bugged IPv6 support. If you wish IPv6 push from our server you need to send the server the "IPV6" user variable set to yes. Therefore you need the following directives (add them in your "Custom configuration" box):: push-peer-info setenv UV_IPV6 yes That said, you must also be aware that some DD-WRT builds do not support IPv6 over IPv4 tunneling with OpenVPN. They keep routing IPv6 packets outside the VPN tunnel. If that's your case, you will need to disable IPv6 on the router to prevent IPv6 leaks, or connect behind the router devices directly, after you have disabled OpenVPN on the router. Kind regards

@Searching Hello! You can safely test Eddie 2.19.7 as no critical problems have been reported so far. If you experience any problem, you can easily roll back to some previous Eddie release. If that's necessary, remember to roll back to Hummingbird 1.1.0 too. If you need a link to re-download older Hummingbird version just ask us. Kind regards

@Searching Hello! Hummingbird 1.1.0 requires macOS Mojave or higher version, while 1.1.1 requires High Sierra or higher version. We will fix the error in the download page. There is no documentation to run Hummingbird from Eddie but it's very simple to do that. From Eddie main window select "Preferences" > "Advanced" and tick "Use Hummingbird". Eddie 2.19.7 or higher version is required (do not try with older versions because they can't launch Hummingbird 1.1.1 properly). See here to download Eddie latest beta release: https://airvpn.org/forums/topic/46329-eddie-desktop-219beta-released/ Kind regards

@airvpnclient 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 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

@mvjfnchd Hello! It's a bug which has been fixed in 1.1.1 version. For a quick workaround: sudo rm /etc/airvpn/* then start Hummingbird again. After the upgrade, you should not experience the issue anymore. https://airvpn.org/forums/topic/48833-linux-airvpn-suite-100-released/ Kind regards

@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

Maybe you already know it. When a country consistently has more than 65-70% allocated (used) bandwidth, we consider the expansion. When a country has consistently more than 90% allocated bandwidth, expansion is mandatory. Currently Canada is around 55% while Sweden less than 50%. However, in Sweden, we have much stronger demand in Stockholm (better peering with various residential ISPs) than Uppsala. If you consider Stockholm as an area of its own, or equivalently Sweden as a country relying essentially on Stockholm, then you have consistently 70% allocated bandwidth. That's why expansion in Stockholm is now under evaluation with higher priority than Canada. Kind regards

@Maggie144 Hello! It's an Eddie bug which has been patched on the fly, can you please re-download the package for Mac when version 2.19.7 is available? It will be released soon. In the meantime, to get higher performance with HB 1.1.1, you can run it directly. Anyway Eddie 2.19.7 will be released very soon. EDIT: you can download now Eddie 2.19.7 featuring the fix. In https://airvpn.org/macos click "Other versions" then select "Experimental". The download page will then point to Eddie 2.19.7. Download and install as usual. Kind regards

Hello! You can now do that with Bluetit. Configuring Bluetit to connect during system bootstrap is a straightforward, very simple procedure, Furthermore, you will run a real daemon, and not a user process, therefore you have a higher security level. and you don't need a systemd unit that's questionable for a user process. Bluetit can start and connect during bootstrap of both systemd and SysV-style init based systems. https://airvpn.org/forums/topic/48833-linux-airvpn-suite-100-released/ Kind regards

Hello! We're very glad to inform you that we have just released Hummingbird 1.1.1 for macOS (High Sierra or higher version required). UPDATE: Apple M1 native version is available too. Main features Lightweight and stand alone binary No heavy framework required, no GUI Small RAM footprint Lightning fast Up to 100% higher throughput than OpenVPN 2.5 Based on OpenVPN 3 library fork by AirVPN Robust leaks prevention through Network Lock based on pf - working perfectly on Big Sur too Proper handling of DNS push by VPN servers What's new Remarkably higher performance Hummingbird 1.1.1 is based on the latest OpenVPN AirVPN library version 3.6.6 linked against OpenSSL, and not mbedTLS anymore. OpenSSL latest versions in macOS have reached higher performance than mbedTLS both in encryption and decryption based on AES and CHACHA20-POLY1305 ciphers. By relying on OpenSSL and thanks to highly optimized compilation as usual, Hummingbird on macOS is now able to beat OpenVPN 2 performance as well as previous Hummingbird 1.1.0 performance. According to our tests performed on macOS Catalina and Mojave, and keeping AES-256-GCM as Data Channel cipher, throughput increases up to 100%. Comparisons have been performed against Eddie 2.19.6 + OpenVPN 2.5, Tunnelblick + OpenVPN 2.4.9 and Hummingbird 1.1.0. All the tests consistently show a great performance boost, starting from +30% and peaking to +100%. Therefore, we strongly recommend that you test Hummingbird 1.1.1 even if you run Eddie. Remember that you can run Hummingbird through Eddie comfortably and quickly by setting the proper option. New OpenVPN 3 library features Starting from version 1..1..1, Hummingbird is 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. The new library also includes a different handling of IV_CIPHERS variable, fixing OpenVPN main branch issues causing 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 Hummingbird 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 Download Hummingbird for macOS is distributed in notarized and plain versions, both for Intel and M1 processors: Check the download page: https://airvpn.org/macos/hummingbird/ The difference is about how the package is seen by macOS security and it is therefore up to the user to pick the distribution file suiting his or her needs best. The notarized version is compliant to macOS software security scheme and runs "out-of-the-box", whereas the plain version needs to be explicitly granted permission to run by the user in macOS security & privacy settings. Please note that both versions ensure the same functionality in connecting a VPN server, it is however up to the user to decide whether using the signed and notarized version or not.

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.

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.

@Dadadadadaa Yes, that's correct. Kind regards

@Dadadadadaa Hello! No doubts, it will be even more useful against flood. Anyway nothing changes for the customers under a security point of view, obviously, as the key is needed as TLS pre-auth (so OpenVPN can shut down immediately, before checking client certificate, and mitigate flood) and for TLS mode (so PFS etc. become possible), nothing else. Kind regards

@moejoe Hello! As far as we know Enigma2 is available for MIPS based machines (Dreambox): if that's your case, we're sorry, but both Eddie and AirVPN Suite are built for i686, x86-64,. ARM (32 and 64 bit), but not MIPS. You need to re-compile them. Eddie needs Mono framework and OpenVPN, if they are not available in your system or anyway Eddie is too heavy for a top box (you will need at least 300 MB RAM free before running it, plus some MB to run OpenVPN and other external binaries), you might try Hummingbird (it will take just 10 MB or less in total), but consider that it does not have a GUI. If you run a Linux based top box with Enigma 2 on top with some ARM CPU, then you might even try Hummingbird directly. https://airvpn.org/hummingbird/readme/ Kind regards

Hello! A few router web servers, by default settings, only accept connections from IP addresses in the LAN for security reasons. That would explain why you get error 111 (connection refused) and the other SSL related issue only when the connection comes from the outside. Checking the router web server configuration is worthwhile. Kind regards

@paladinair A couple of ideas coming to mind: 1) You run some curl version linked to a library that does not support the underlying cipher that your server proposes 2) You run some curl version linked to a library that does not support the TLS protocol required by your server (example: your server requires TLS 1.x and curl does not support it) Kind regards

@monstrocity Hello! We will investigate. Can you confirm that the problem does not occur in HB 1.1.0? Please note that Bluetit 1.0.0 RC 1 does not have the ability to enforce network lock and a connection at system bootstrap. Bluetit 1.0.0 stable release will have this ability, but of course it will be optional. Can you also send us whole terminal output after you have pressed CTRL-C (or have sent a SIGTERM to HB process), as well as the content of /etc/airvpn? ls -l /etc/airvpn Kind regards
