Hello! UPDATE 29-Nov-19: macOS, Linux x86-64 bit and Raspbian beta versions now available. UPDATE 06-Dec-19: beta 2 version has been released UPDATE 10-Dec-19: Release Candidate 1 has been released UPDATE 19-Dec-19: Release Candidate 2 has been released UPDATE 27-Dec-19: version 1.0 has been released UPDATE 24-Jan-20: version 1.0.1 has been released We are very glad to introduce Hummingbird, a new client software for: Linux x86-64 bit Linux Raspbian 32 bit (frequently installed in Raspberry PI) Linux ARM 64 bit (tested under Raspberry 4 Ubuntu 19.10) Mac (minimum required version macOS Mojave) based on our own AirVPN OpenVPN 3 library. The software meets various demands by many users. Furthermore, 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. Note: ChaCha20 support for Android had been already implemented in our free and open source Eddie Android edition https://airvpn.org/forums/topic/44201-eddie-android-edition-24-released-chacha20-support/ robust leaks prevention through Network Lock based either on iptables, nftables or pf 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 FreeBSD and OpenBSD will follow in the future.

Note on Checksum Files We do strongly suggest you to check the integrity both of the distribution tar.gz file and the hummingbird binary in order to make sure you are installing a binary created and fully supported by AirVPN. Hummingbird is an open source project and, as such, its source code can be downloaded, forked and modified by anyone who wants to create a derivative project or build it on his or her computer. This also means the source code can be tampered or modified in a malicious way, therefore creating a binary version of hummingbird which may act harmfully, destroy or steal your data, redirecting your network traffic and data while pretending to be the "real" hummingbird client genuinely developed and supported by AirVPN. For this reason, we cannot guarantee forked, modified and custom compiled versions of Hummingbird to be compliant to our specifications, development and coding guidelines and style, including our security standards. These projects, of course, may also be better and more efficient than our release, however we cannot guarantee or provide help for the job of others. You are therefore strongly advised to check and verify the checksum codes found in the .sha512 files to exactly correspond to the ones below, that is, the checksum we have computed from the sources and distribution files directly compiled and built by AirVPN. This will make you sure about the origin and authenticity of the hummingbird client. Please note the files contained in the distribution tarballs are created from the very source code available in the master branch of the official hummingbird's repository. Checksum codes for Version 1.0 The checksum codes contained in files hummingbird-<os>-<arch>-1.0.1.tar.gz.sha512 and hummingbird.sha512 must correspond to the codes below in order to prove they are genuinely created and distributed by AirVPN.

Hummingbird 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's Client Area Start a connection: sudo ./hummingbird your_openvpn_file.ovpn Stop a connection: Type CTRL+C in the terminal window where hummingbird is running. The client will initiate the disconnection process and will restore your original network settings according to your options. Start a connection with a specific cipher: sudo ./hummingbird --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: they are marked in yellow as "Experimental ChaCha20". Disable the network filter and lock: sudo ./hummingbird --network-lock off your_openvpn_file.ovpn Ignore the DNS servers pushed by the VPN server: sudo ./hummingbird --ignore-dns-push your_openvpn_file.ovpn Please note: the above options can be combined together according to their use and function. Network Filter and Lock Hummingbird's network filter and lock natively uses iptables, nftables and pf in order to provide a "best effort leak prevention". Hummingbird will automatically detect and use the infrastructure available on your system. Please note: Linux services firewalld and ufw may interfere with the hummingbird's network filter and lock and you are strongly advised to not issue any firewall related command while the VPN connection is active. DNS Management in Linux Hummingbird currently supports both resolv.conf and systemd-resolved service. It is also aware of Network Manager, in case it is running. While 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. Furthermore, please note that if your network interfaces are managed by Network Manager, DNS settings might be changed under peculiar circumstances during a VPN connection, even when DNS push had been previously accepted. DNS Management in macOS DNS setting and management is done through OpenVPN3 native support Recover Your Network Settings In case hummingbird crashes or it is killed by the user (i.e. kill -9 `pidof hummingbird` ) 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; therefore, 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 ./hummingbird --recover-network Please note: in case of crash or unexpected exit, when you subsequently run hummingbird 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.

Hello! All Air VPN servers do not keep any account data, not even client key, so no worries under this respect. VPN servers also don't keep log. We also remind you that you are not required to enter personal information in your account, not even a real e-mail address. Please note that the investigation that was disclosed by the press pertains to datacenter owners and a few web sites hosted in it, and did not involve AirVPN and/or AirVPN servers in any way at any stage. Air VPN servers were not seized and were not disconnected: we decided to drop the datacenter and withdraw the servers because of repeated lack of IPv6 connectivity, frequent drop-outs and packet loss, as well as very slow customer care reactions (maybe an impact from the investigation when it was made public? we don't know) to solve problems. As you know our technical requirements are quite precise and if a datacenter fails repeatedly to meet them we are forced to look elsewhere, otherwise the overall perceived quality by our customers will go down. Kind regards

Hello! OpenVPN AirVPN 1.0 Release Candidate 1 has just been released! Please check the first post in this thread for updated links, instructions and changelog. Kind regards 

Hahah =] The problem doesn't exist anymore but when it did the problem was that the VPN wasn't allowing traffic through. I am not sure why, my settings are above but after a reboot it started working. So maybe the router was confused with all the information going in with out a reboot. Idk...

Hello! The datacenter operations might be impaired by the charges against the datacenter management issued on last June and related to crimes allegedly committed in 2012: https://www.cp24.com/news/owners-of-toronto-web-hosting-company-charged-in-massive-child-pornography-bust-1.4474497 Although our VPN servers in that datacenter have still IPv4 connectivity, only on some IP addresses, we can't of course count on them reliably. We are therefore shutting them down. Infrastructure in Canada remains with 31 servers capable of 1 Gbit/s bandwidth each, which provide wide redundancy, and we will anyway enlarge it whenever necessary. Kind regards

Sorry, Windows 7. I tried http://ipleak.net/ and in the middle it shows the IP of the DNS of my ISP even though I entered 10.4.0.1 (or is it 10.0.4.1? I found different things in this forum...) as DNS. Best, Demon Slayer
