Hello! We would like to check it out as this is not what we experience: what is the Shield version in your device? By chance, are you using the brand new remote command from nVidia (the one with back lighted keys)? We ask because it's the only remote command we don't have in our testing systems and Eddie was released when it did not exist. Important: by using profiles you will not need a Master Password. Kind regards

Hello! Currently Netflix is not accessible from our infrastructure. We are working on the problem. As usual, we can't promise anything on such peculiar subject. The proper source of information, which is frequently updated, is our post in the correct forum: Kind regards

@HannaForest Hello! Yes, that's correct: airvpn.org is with Ovh in France. Kind regards

Hello! Entering a Master Password in Eddie Android edition does not require a mouse on nVidia Shield and Shield Pro. You can enter it via the remote control or the joypad. You can also use a profile to skip any Master Password requirement. Instructions for Eddie Android edition are here: https://airvpn.org/forums/topic/29660-using-airvpn-with-eddie-client-for-android/ Kind regards

Hello! We have good relations both with OvH and M247. The problem in France is different, we have explained it many times so we will not explain it again here in details, and is related to the illegal framework of the country pertaining to data retention and the inability of the European Commission to incisively start an infraction procedure against France (and Italy as well). As we already fight the illegal position of other EU countries on data retention we need to focus resources. Kind regards

Hello! We're very glad to inform you that a new 1 Gbit/s server located in Riga, Latvia, is available: Felis. The AirVPN client will show automatically the new server; if you use any other OpenVPN client you can generate all the files to access it through our configuration/certificates/key generator (menu "Client Area"->"Config generator"). The server accepts connections on ports 53, 80, 443, 1194, 2018 UDP and TCP. Just like every other "second generation" Air server, Felis supports OpenVPN over SSL and OpenVPN over SSH, TLS 1.2 and tls-crypt. Full IPv6 support is included as well. As usual no traffic limits, no logs, no discrimination on protocols and hardened security against various attacks with separate entry and exit-IP addresses. You can check the server status as usual in our real time servers monitor: https://airvpn.org/servers/felis Felis brings for the first time 1 Gbit/s connections availability in Latvia meant to replace in the very near future all the current 100 Mbit/s ports and lines. Do not hesitate to contact us for any information or issue. Kind regards and datalove AirVPN Team

Hello! We're very glad to inform you that a new 1 Gbit/s server located in Berlin, Germany, is available: Cujam. The AirVPN client will show automatically the new server; if you use any other OpenVPN client you can generate all the files to access it through our configuration/certificates/key generator (menu "Client Area"->"Config generator"). The server accepts connections on ports 53, 80, 443, 1194, 2018 UDP and TCP. Just like every other "second generation" Air server, Cujam supports OpenVPN over SSL and OpenVPN over SSH, TLS 1.2 and tls-crypt. Full IPv6 support is included as well. As usual no traffic limits, no logs, no discrimination on protocols and hardened security against various attacks with separate entry and exit-IP addresses. You can check the server status as usual in our real time servers monitor: https://airvpn.org/servers/cujam Do not hesitate to contact us for any information or issue.

@nick75 Hello! Yes, actually this is planned, please stay tuned. :) Kind regards

Hello! All AirVPN servers support IPv6 except Kitalpha and Metallah, which are operational inside datacenters that do not have an IPv6 infrastructure at all. Unfortunately, intermittent IPv6 related problems affect the servers you mentioned. Such problems are caused by IPv6 "black outs" in the respective datacenter. We have already contacted datacenter technicians asking for a problem resolution. Kind regards

@usefulvid Thank you. We have reviewed the four tickets (all by the same user) which in your opinion hint to bad support and we don't agree with you. They have all been handled very professionally as far as we can see, and in our opinion, even when the problem of the user was unrelated to AirVPN and therefore totally out of the scope and competence of the support team. Kind regards

@monstrocity Hello, we're very glad to see that the problem is resolved. 2048 packets make the output queue huge, but actually it is proportional to the amount of concurrent connections limit you have set in your torrent software. qBittorrent comes with a limit of 500 by default. The other error you report pertains to a disconnection, unrelated to TCP_OVERFLOW. If you get such disconnections more often when you torrent, please warn us. For the readers: overflow in the TCP output queue is a problem that does not exist in UDP. Kind regards

@56Kmodem @monstrocity Updated thread with a tested solution which hopefully will be confirmed by you both is here: Kind regards

@monstrocity Please increase the maximum amount of packets allowed in the TCP queue with directive tcp-queue-limit n (n is the amount of packets) according to the amount of concurrent, global TCP connections your system needs when you run a BitTorrent software. OpenVPN 3 default limit is 64 packets. For example, add to your profile the following line: tcp-queue-limit 256 Please test again and check whether the problem is resolved. Of course consider to increase the amount of packets beyond 256 if you see the problem persisting. Your feedback is very much appreciated. Kind regards

@inradius It's exactly the contrary. Canada servers rarely need to provide more than 33% bandwidth they are capable of. Even considering the 40% you mention, our infrastructure in Canada is largely OVER sized with enormous availability of traffic and bandwidth. On 90% of the time, you have 18 Gbit/s availability in Canada which is never used by anyone. The issues you mention can not be related to servers available bandwidth, you must have some problem on your side or something else, outside our servers, is the cause of the problem with YouTube etc. Adding servers would be perfectly useless in your case. You might like to open a ticket to investigate the issue more properly. Kind regards

@usefulvid 1) CHACHA20 is not experimental on the client side but yes, it is experimental on the server side because OpenVPN 2.5 is still not in stable phase, although it was promised for November/December 2019. That's why we prefer to clarify it. 2) We don't know why they stick to obsolete versions. OpenVPN 2.4 without tls-crypt supports OpenVPN up to 2.2 so it is not a problem for Windows XP and onwards... OpenVPN 2.3.x should not be necessary anymore for any backward compatibility. Thanks for the answers. Staff account does not have PM enabled for flood reasons, please contact us at your convenience either at info@airvpn.org or open a ticket with usefulvid subject (or from your usefulvid account). Kind regards

@usefulvid Are we correct in noticing that no mention of CHACHA20-POLY1305 (boosting performance of non AES-NI supporting devices and adding dramatically battery life of battery based devices) has been done? If we are right, has it been omitted because it is not considered relevant, or for some other reason? Also, is the fact that AirVPN develops OpenVPN 3 not perceived as relevant by your audience? Candid questions whose answers may be useful to us, but of course feel free to not answer. Important disclaimer for the readers: the author of the review has never been paid, either directly or indirectly, by AirVPN. Congratulations for being one of the few who did not ask for money "or else...". Kind regards

@usefulvid Please point us to the ticket that has not been answered properly. Kind regards

@giganerd Hi, it should be "impossible" and not "more difficult" by deep inspecting the packets. Are you aware of any new method that can find out you're using OpenVPN by only analyzing the flow (i.e. without knowing that on the destination IP address OpenVPN answers)? Kind regards

@monstrocity Hello! Bug detected and under investigation. It involves all versions of OpenVPN 3 library (not only our fork unfortunately) so it must be something we have been dragging with us since the very beginning, OR (worst case scenario) something related to asio library (hopefully not). If you have the option to use UDP, please do it, otherwise stay tuned, we have given very high priority to the bug. Kind regards

@pjnsmb Hello! Hummingbird tries to use in sequence the first available firewall between iptables, iptables-legacy, nftables and pf. In your case, Hummingbird finds iptables-legacy. With IPv4 no errors seems to arise, but the problem comes out with IPv6. ip[6]tables-legacy is a wrapper to nftables, so IPv6 support in nftables might be the problem, or maybe it's a bug in ip6tables legacy in your unstable distribution (or you just disabled IPv6 support in your system, but you told us that you keep getting the error even when you re-enable it, can you confirm?). Can you please re-test Humminbird without the --ipv6 no option you enforced, just in case, and check whether the problem is the same or not? Another possible test, but it's more problematic if you need iptables syntax somewhere in your system or applications, would be removing iptables and iptables-legacy packages. In this case Hummingbird will use nftables. We can not support unstable distributions (you're running Debian Sid according to your ticket) because we can't circumvent all the possible bugs which an unstable distribution may potentially come with: it would be a wrong approach and anyway it would be an overwhelming task. However, we will offer in a near future release the option to force Hummingbird to use a firewall chosen by the user. When the option is available you will be able to force usage of nftables, bypassing iptables-legacy, if it's causing the issue. Please keep us informed if you decide to perform any of the above tests. Kind regards

Hello! We're glad to inform you that Hummingbird 1.0.1 has just been released. Hummingbird is a free and open source software by AirVPN for: Linux x86-64 Linux ARM 32 (example: Raspbian for Raspberry PI) Linux ARM 64 macOS (Mojave or higher version required) based on OpenVPN3-AirVPN 3.6 library supporting CHACHA20-POLY1305 cipher on OpenVPN Data Channel and Control Channel. Hummingbird is very fast and has a tiny RAM footprint. AES-CBC and AES-GCM are supported as well. Version 1.0.1 uses new OpenVPN3-AirVPN 3.6.2 library which features various improving minor changes and fixes an annoying bug which caused "ncp-disable" directive to be ignored in profiles. Note: command line options --ncp-disable and --cipher, when specified, override profile directives. Please consult the following page for details, changelog, instructions and download links. https://airvpn.org/hummingbird/readme/ Hummingbird source code is available here: https://gitlab.com/AirVPN/hummingbird OpenVPN3-AirVPN library source code is available here: https://github.com/AirVPN/openvpn3-airvpn Important: Hummingbird is not aimed to Android. To have CHACHA20-POLY1305 on Android, please run our software Eddie Android edition, which uses our OpenVPN3-AirVPN library. Kind regards

@pjnsmb Hello! You are still running Hummingbird directly. To run it through Eddie (so you have Network Lock by Eddie) please see here: https://airvpn.org/forums/topic/45326-eddie-desktop-218beta-released/?do=findComment&comment=103687 Kind regards

@pjnsmb Hello! Thank you very much, we will investigate. Now you can even use Hummingbird via Eddie, if you wish so, because Network Lock is enforced by Eddie even when it runs Hummingbird. Of course please make sure that Network Lock is applied properly, just in case. Kind regards
