  1. Hello, last year I had written a wrapper for Eddie's CLI version (in bash) to be able to use it more easily and extensively in the linux command line like the GUI, but with less resources. I have used it since then every day without problems, but now I have finally gotten to overhaul it and adjust it to Hummingbird because it is just so much faster! I also tried to make it more easy to configure (by having a separate configuration file) and added some new functionality like support (and automatic recognition) of iptables and nftables to lock down the system even without being connected to AirVPN and automatic connection at boot with a systemd unit. Again, feel free to use this as you wish, I hope someone can benefit from this. I'm happy about any improvements and corrections and will update this if I find the time. Features graphical interface in the command line to connect to AirVPN with Hummingbird (no Eddie involved) runs in background, the interface can be closed/opened anytime without affecting the running connection possibility to connect to any server with just one ovpn configuration file easily connect to a random server, to a recommended server, to the recommended server of a specific country or to a specific server sortable list of all servers including info like used bandwidth, load and number of users possibility to connect to other VPNs with openconnect lock down system by default (permanently if you want), so even without AirVPN/Hummingbird running there won't be any unwanted network traffic automatically establish connection at boot (which can later be controlled via the interface) logging of Hummingbird's output (number of days to keep logs for can be adjusted) system notifications to let you know what happens in the background Some general notes The default network lock determines, like Hummingbird itself, if iptables, iptables-legacy or nftables is available on your system and will use the first one found in that list. You can overwrite that by specifying which one to use in the configuration file. Once activated, the lock will stay in place until manually deactivated, so no internet connection will be possible unless connected to AirVPN or other whitelisted VPNs. You can make the lock permanent (or rather activate at boot) by enabling that option in the configuration file. AirVPN's network lock overwrites the default network lock, so there will be no interference. IMPORTANT: If you have any frontend firewall for iptables/nftables running, you might to disable that or read up on how it might interfere with rule changes you make directly via iptables/nft. The same thing applies if you use just Hummingbird itself. If you enable the default permanent network lock, it will write the lock rules at boot, most likely overwriting rules by firewalld or the like, but other enabled firewalls might interfere later. Also important: If you have SELinux and you want to use nftables for Hummingbird starting at boot, you have to create a SELinux exception for nft bcause otherwise it will be denied and Hummingbird starts without setting up its own lock, thus leaving you unprotected (AirVPN staff is aware of this issue). You can do that with audit2allow. Follow for example this guide to troubleshoot the problem and fix it with the solution given by sealert. Check your /etc/resolv.conf file while not running Hummingbird (because Hummingbird's network lock replaces that file temporarily) to make sure your router is not set as a nameserver (so no 192.168... address). Some routers will push themselves on that list by DHCP whenever you connect to their network. Since communication with the router is allowed in the lock rules, DNS requests will be handled by the router and sent to whatever DNS server is configured there even when network traffic should be blocked. There are ways to prevent that file from being changed by DHCP, best configure network manager for that if you use it. To connect to other VPNs, their IPs must be whitelisted and DNS requests for their domains must be allowed in the default network lock rules (netfilter_ipbatles.rulesipv4/ipv6 and/or netfilter_nftables.rules). Only edit those files with the default network lock deactivated. The rules for airvpn.org can be copied and adjusted. You can set custom options for Hummingbird in the interface or the configuration file. All the possible options can be found in the Hummingbird manual or with sudo hummingbird --help Apart from dialog I tried to only use basic system tools. The scripts will check if everything needed is present, if not they will exit. At least bash 4 is needed. The scripts rely mostly on dialog, awk and curl (and iptables/nft as described and openconnect if needed), so it should work on most systems. I wrote and tested this on Fedora 32 with Hummingbird 1.0.3. It should be possible to use any ovpn config file generated by the AirVPN's config generator. Even with the file for one specific server it should be possible to connect to any other server because the server override function is used here. I haven't tested that extensively though and just use the config file for earth. AirVPN's API seems to be a little unreliable sometimes as in not correctly reporting the connection status. Sometimes the API reports me not being connected although I am connected to an AirVPN server. This is no big deal, it just means that the connection status sometimes may be shown falsely as disconnected. If you have the default network lock activated, no traffic would be possible if you were actually disconnected. And, lastly, VERY IMPORTANT: I am still no programmer and do this only on this on the side, so even though I tried my best to make these scripts secure and error free, there might very well be some bad practice, never-ever-do-this mistakes or other hiccups in there. It works very well for me (and has for quite a while by now), but better check it yourself. Installation Make sure you have the prerequisites installed: dialog, bash >=4, curl and awk. Copy the content of all the files to separate files on your computer, name them accordingly, and put them in the appropriate folders. It says where they belong above the file contents. Make sure to change the ownership of the systemd unit file to root:root and give the scripts execute permissions. Alternatively download the VPNControl.tar, cd into the directory where VPNControl.tar has been downloaded to and enter the following commands: tar -xvf VPNControl.tar mkdir -p "$HOME/.vpncontrol/config" && mkdir "$HOME/.vpncontrol/logs" mv vpncontrol.conf "$HOME/.vpncontrol/config/" mv netfilter_* "$HOME/.vpncontrol/config/" mv VPNControl.sh "$HOME/.local/bin/" sudo mv airvpn_boot.sh "/usr/local/bin/" sudo chown root:root airvpn.service sudo mv airvpn.service "/etc/systemd/system/" Generate a config file with AirVPN's OpenVPN Config Generator (I use the one for "Earth", but theoretically it should work with any) and put it in the config directory. Adjust the path name in the configuration file. The script assumes you have all the configuration files in the folder $HOME/.vpncontrol/config/, logs in $HOME/.vpncontrol/logs/ and the boot script in /usr/local/bin/. In the airvpn_boot.sh-script you have to adjust the path for the source command (line 34) to point to the configuration file. If you want to use different locations, you have to change them in the configuration file and (for the boot script) in the systemd unit file. If you want to use a different location for the configuration file itself, you have the change the VPNCONTROL_CONFIG variable in the VPNControl.sh-script and again the source path in the airvpn_boot.sh-script. The VPNControl.sh-script is meant to be run as a regular user. If you want to run it as root, you have to for sure change the VPNCONTROL_CONFIG variable from the previous step. Otherwise it should be possible to run it as root without problems (except notifications), but I haven't tested it. You need to insert your own API key in the configuration file. It can be found in your account under Client Area -> API. Without this, connections will still work, but user info and connection status in the main window will not be properly updated. Enable the systemd unit with sudo systemctl daemon-reload sudo systemctl enable airvpn.service If you use a setup where bash cannot be found at '/usr/bash', you have to change the path in the unit accordingly. Also I ran into a problem where systemctl complained that it couldn't find the unit. I don't know what the cause was (pretty sure the ownership and permissions were right), but it worked after I duplicated another .service file already present in /etc/systemd/system (with sudo cp) and then renamed it and exchanged the contents. Disable firewall frontends if needed (e. g. firewalld) and if you want to use the default network lock. (Firewall daemons don't necessarily interfere, but have the ability to overwrite the lock any time.) DONE! Now Hummingbird will try to establish a connection after boot. You can call the control script at any time with VPNControl.sh and disconnect/reconnect/do whatever. The script can be exited without affecting the running connection. Files These are all the necessary files (scripts and configuration files) with their default locations. Be aware that there might be a problem when manually copying the contents from here to text files where unwanted characters are inserted. If that's the case, please download the attached archive (at the very bottom of this post) and use the files from there. For the future I plan to put this somewhere more easily accessible like Gitlab.

  2. Hi. I am using this systemd unit file to start eddie-ui. It's working well at the startup of my server. But sometime, i want to stop it to make some tests. So, I stop it with a "systemctl stop airvpn.service". A kil SIGTERM signal is sent by systemd to the eddie to stop it, but it don't close gracefully, some errors are generated. Often after a stop, my server can't access the network, I can't restart Eddie and I have to reboot my server. There is a way another way stop an running eddie-ui batch process other than sending a SIGTERM signal? Thanks There is le log of what happening whene systemd stop my service : (i'm running on Unbutu 18) avr 18 14:43:13 systemd[1]: Stopping AirVPN Client (Eddie)... avr 18 14:43:13 eddie-ui[26906]: . 2020.04.18 14:43:13 - Above log line repeated 1 times more avr 18 14:43:13 eddie-ui[26906]: . 2020.04.18 14:43:13 - Received signal SIGTERM avr 18 14:43:13 eddie-ui[26906]: . 2020.04.18 14:43:13 - Shutdown in progress avr 18 14:43:13 eddie-ui[26906]: ! 2020.04.18 14:43:13 - Disconnecting avr 18 14:43:18 eddie-ui[26906]: F 2020.04.18 14:43:18 - Unexpected crash of elevated helper:Connection reset by peer avr 18 14:43:18 eddie-ui[26906]: . 2020.04.18 14:43:18 - Routes, removed a route previously added, xxx.xxx.xxx.xxx for gateway xxx.xxx.xxx.xxx avr 18 14:43:18 eddie-ui[26906]: W 2020.04.18 14:43:18 - Routes, add xx:xx:xx:xx:xx for gateway xx:xx:xx:xx:xx failed: Connection reset by peer avr 18 14:43:18 eddie-ui[26906]: . 2020.04.18 14:43:18 - Connection terminated. avr 18 14:43:18 eddie-ui[26906]: . 2020.04.18 14:43:18 - DNS of the system restored to original settings (Rename method) avr 18 14:43:18 eddie-ui[26906]: E 2020.04.18 14:43:18 - Fatal error occured, please contact Eddie support: Connection reset by peer - at Eddie.Core.ElevatedProcess.DoCommandSync (Eddie.Core.ElevatedProcess+Command c) [0x0002b] in <858605a5cb284b46ae78a1a5be9f3a18>:0 avr 18 14:43:18 eddie-ui[26906]: E 2020.04.18 14:43:18 - at Eddie.Core.ElevatedProcess.DoCommandSync (System.String command) [0x00017] in <858605a5cb284b46ae78a1a5be9f3a18>:0 avr 18 14:43:18 eddie-ui[26906]: E 2020.04.18 14:43:18 - at Eddie.Platform.Linux.Platform.OnDnsSwitchRestore () [0x00031] in <2ef95171729245d8aab83614036a9dd3>:0 avr 18 14:43:18 eddie-ui[26906]: E 2020.04.18 14:43:18 - at Eddie.Core.Threads.Session.OnRun () [0x00d7a] in <858605a5cb284b46ae78a1a5be9f3a18>:0 avr 18 14:43:18 eddie-ui[26906]: . 2020.04.18 14:43:18 - Flushing DNS avr 18 14:43:18 eddie-ui[26906]: [ERROR] FATAL UNHANDLED EXCEPTION: System.Exception: Connection reset by peer avr 18 14:43:18 eddie-ui[26906]: at Eddie.Core.ElevatedProcess.DoCommandSync (Eddie.Core.ElevatedProcess+Command c) [0x0002b] in <858605a5cb284b46ae78a1a5be9f3a18>:0 avr 18 14:43:18 eddie-ui[26906]: at Eddie.Core.ElevatedProcess.DoCommandSync (System.String command, System.String key1, System.String val1) [0x00024] in <858605a5cb284b46ae78a1a5be9f3a18>:0 avr 18 14:43:18 eddie-ui[26906]: at Eddie.Platform.Linux.Platform.FlushDNS () [0x0002e] in <2ef95171729245d8aab83614036a9dd3>:0 avr 18 14:43:18 eddie-ui[26906]: at Eddie.Core.Threads.Session.OnRun () [0x00fd6] in <858605a5cb284b46ae78a1a5be9f3a18>:0 avr 18 14:43:18 eddie-ui[26906]: at Eddie.Core.Thread.DoRun () [0x00000] in <858605a5cb284b46ae78a1a5be9f3a18>:0 avr 18 14:43:18 eddie-ui[26906]: at System.Threading.ThreadHelper.ThreadStart_Context (System.Object state) [0x00017] in <8f2c484307284b51944a1a13a14c0266>:0 avr 18 14:43:18 eddie-ui[26906]: at System.Threading.ExecutionContext.RunInternal (System.Threading.ExecutionContext executionContext, System.Threading.ContextCallback callback, System.Object state, System.Boolean preserveSyncCtx) [0x0008d] in <8f2c484307284b51944a1a13a14c0266>:0 avr 18 14:43:18 eddie-ui[26906]: at System.Threading.ExecutionContext.Run (System.Threading.ExecutionContext executionContext, System.Threading.ContextCallback callback, System.Object state, System.Boolean preserveSyncCtx) [0x00000] in <8f2c484307284b51944a1a13a14c0266>:0 avr 18 14:43:18 eddie-ui[26906]: at System.Threading.ExecutionContext.Run (System.Threading.ExecutionContext executionContext, System.Threading.ContextCallback callback, System.Object state) [0x00031] in <8f2c484307284b51944a1a13a14c0266>:0 avr 18 14:43:18 eddie-ui[26906]: at System.Threading.ThreadHelper.ThreadStart () [0x0000b] in <8f2c484307284b51944a1a13a14c0266>:0 avr 18 14:43:18 systemd[1]: Stopped AirVPN Client (Eddie).

  4. Hello, after I posted some suggestions for Eddie's CLI version in this thread and received some helpful information there, I set out to write my own little interface in bash for it to implement the suggestions. Being no programmer it turned out to be quite a project for me, and I would like to share it here in case anybody else prefers to run Eddie in the terminal rather than as a full GUI application. This script still uses Eddie itself, it's just a wrapper to make it as easy to use in the command line as it is as a desktop application. Screenshots are attached. Some features and advantages: uses less resources (top shows usually 0.3% CPU usage compared to 4-5% for the desktop version) can be exited without disconnecting interactive, sortable server list option to connect to another VPN with openconnect (since I need to do that from time to time, but it should be easy to add other connection methods as well) option to lock down the system's network traffic by default, so even without Eddie running with its own network lock there will be no leaks What to watch out for: The default network lock works with direct rules in firewalld because I'm using Fedora. It should be easy to change it to use iptables directly on other distributions since firewalld's direct rules are just a way to directly manipulate iptables. Once activated, the lock will stay in place until manually deactivated (also surviving reboots), so no internet connection will be possible unless connected to AirVPN or other whitelisted VPNs. AirVPN's network lock overwrites the default network lock, so there will be no interference. Check your /etc/resolv.conf file while not running Eddie (because Eddie's network lock replaces that file temporarily) to make sure your router is not set as a nameserver (so no 192.168... address). Some routers will push themselves on that list by DHCP whenever you connect to their network. Since communication with the router is allowed in the lock rules, DNS requests will be handled by the router and sent to whatever DNS server is configured there even when network traffic should be blocked. There are ways to prevent that file from being changed by DHCP, best configure network manager for that if you use it. To connect to other VPNs, their IPs must be whitelisted and DNS requests for their domains must be allowed in the default network lock rules. The rules for airvpn.org can be copied and adjusted. I haven't yet included an option to pass command line arguments to Eddie. So if you need to set more advanced options like black-/whitelists, use of certain protocols etc., you need to set them manually in the connect_server function. All the possible options can be found in 'man eddie-ui'. You need to insert your own API key in line 5. It can be found in your account under Client Area -> API. Without this, connections will still work, but user info and connection status in the main window will not be properly updated. I tried to only use basic system tools. The script relies mostly on dialog, awk and curl (and firewalld as described and openconnect if needed), so it should work on most systems, but I'm not sure. And, lastly, VERY IMPORTANT: As I said, I'm no programmer and new to this, so even though I tried my best to make this script secure and error free, there might very well be some bad practice, never-ever-do-this mistakes or other hiccups in there. It works well for me, but better check it yourself. Feel free to use this as you wish, I hope someone can benefit from this. I'm happy about any improvements and corrections and will update this if I find the time.

  5. Hello. I've been very happy with Air so far, thank you for the great service! I have some improvement suggestions/requests for the CLI version of the Eddie client though. I prefer to not run the GUI version for everyday use since it uses up more resources (not crazy much, but mono has 4-5% CPU usage while the CLI version always uses <1%). But what keeps me from using it is that there seems to be no way to disconnect from a server or reconnect to another without exiting Eddie and thus disabling the network lock. It would be great to make the client more interactive as in being able to disconnect from a server and have Eddie be in "idle" with still having the network lock enabled and, as another suggestion, be able to connect to a specific server from there again (rather than the recommended one). Maybe even implement a possibility to request an interactive server list like the ProtonVPN CLI client has it. Also as a minor improvement I would suggest that the CLI client defaults to loading the default profile from ~/.airvpn and not the one in the root folder since the first one is where the login data is stored. Thank you!
  6. Hi, as i've write in other topic, seems we can't launch eddie-ui GUI client in tails 3.7.1 without crash of app. (seems permission-related question, i've tried some change and the use of torsocks but none works) So i've to use command line interface; it's necessary to add specific option to connect to airvpn over tor ? I think i should add something to command line.. i cant use only : "airvpn -cli -login=mynick -password=mypassword" Could someone gently post the simple base command line to obtain vpn over tor connection ? i'm sure it would be very useful have a simple working command line for start the ball rolling.
  7. Hello, I can successfully run the Eddie CLI and connect by issuing sudo ~/airvpn -cli -connect However, I want to put this line into a shell script "vpn.sh" so that I con't have to type all this every time I connect, but instead just issue "vpn.sh". When I do this, the program doesn't connect but instead I get a small graphical window with the title "Eddie" and the content "Lib.Platform.Linux.Native.so". This also happens when I set an alias for the long command in my .bashrc. Does anyone know why that happens, and how to avoid it? If there's another, better solution to my problem, I'm also happy to hear about it. Thanks in advance. /Edit: Okay, this is mighty weird: *Sometimes*, this command throws the same error: sudo /home/beefcake/files/Software/eddie-ui_2.13.6_linux_x64_portable/airvpn -cli -connect I've had two bash windows open where it worked in one, and failed in the other. If I issue these commands, it works: cd /home/beefcake/files/Software/eddie-ui_2.13.6_linux_x64_portable/ sudo ./airvpn -cli -connect
  8. setup: headless ubuntu 14.01 command: sudo /usr/bin/airvpn -cli -login='xxxx' -password='xxxxx' -connect -netlock problem: my subscription lapsed and when disconnected the netlock didn't work. got about 10 torrent dmca warnings. lol i have also seen this problem one other time. I noticed that when i had no download limit set on my torrent app and it reached a certain limit my connection would die. Im guessing on the server side. I set a limit of 9mb down and that fixed it. When it would disconnect again the netlock didn't work. I know the root of the problem is my procrastination but it would be cool if the netlock still protected me.
  9. Last week I built Eddie 2.11.x from your DEB file on Ubuntu Xenial, with no problems. Over the weekend I began testing but soon ran into a bug whereby the client would try one server after another but fail with TAP/TUN problems. I sent you the logfile appended to support request 66876, but have not heard back so far. See appended file airvpn-linux-client-OUT for more information. The graphic interface is nice but I would like to build a CLI version without the overhead of the GUI. I have cloned the sources from Github. I need a way to toggle the build process into producing a cli only version. In a conventional linux build system there would be a flag in the toplevel Makefile to do this. However that will not work in this case as the build process here is completely opaque. Can you please provide me with a means to do this, or as a last resort, provide me with the source code for src/Deploy/bin/Release/Deploy.exe? Perhaps you have already produced a CLI only version of Eddie 2.11 somewhere? airvpn-linux-client-OUT.txt
  10. Two different topics in the same post since I can only make a single post a day. Sorry. First, what is the proper way to set the.ovpn configuration file in order to enable VPN through Tor? I have attempted using 127.0.0.1 as the SOCKS proxy but that has not worked. Maybe it has something to do with the control port? Second, I have been able to get Eddie started on CentOS 7, but for some reason, Eddie does not connect to any server. I used all default settings once, and then disabled DNS check.

  11. I've downloaded the mono version of the AirVPN client to run on my Raspberry Pi, but I seem to be having an issue getting it up and running on my Arch Linux Arm installation. The problem appears to be that the AirVPN client passes a bad parameter or parameters to my local OpenVPN binary. Unfortunately, I cannot use the OpenVPN binary distriuted with the mono client, as it is not suitable for the ARM architecture. The client also straingely appears to refuse to read certain configuration parameters from my profile, but that is a secondary concern for the time being. The command line invocation, application startup, and profile options are included below. Please note that although the application appears to be using the binaries with which it was distributed, these have been replaced with symlinks to my system's binaries. I'd be happy to provide any additional information, and thanks in advance for any assistance! /usr/local/etc/airvpn/system.xml <options> <option name="areas.blacklist" value="de,us" /> <option name="executables.openvpn" value="/usr/bin/openvpn" /> <option name="executables.ssh" value="/usr/bin/ssh" /> <option name="executables.ssl" value="/usr/bin/stunnel" /> <option name="openvpn.custom" value="/usr/bin/openvpn" /> </options> /usr/bin/mono /opt/airvpn_linux_x86_mono/AirVPN.exe -cli -profile=/usr/local/etc/airvpn/system.xml Oct 29 00:46:57 lanvpn mono[19286]: I 2014.10.29 00:46:57 - AirVPN client version: 2.7, System: Linux, Architecture: Unknown Oct 29 00:46:58 lanvpn mono[19286]: . 2014.10.29 00:46:58 - Reading options from /usr/local/etc/airvpn/system.xml Oct 29 00:46:59 lanvpn mono[19286]: I 2014.10.29 00:46:59 - Press 'X' to Cancel, 'B' to reconnect to the best available server.

  12. Hi, I would like to access AirVPN through the command line on my Mac (OSX). Is this possible? Is there a command line interface (CLI)? Do I need to install OpenVPN first? Thank you.
  13. I'm not sure if anyone else would find this useful, but I threw together a simple script the other day for speeding up the process of configuring and managing my VPN connections on my desktop (Linux Mint). Note that this is far from comprehensive--I made it with my use cases in mind. https://github.com/mindcruzer/airvpn-cli ex. ~$ airvpn setup pavonis --connect Would prompt you for your username and password, generate the configuration, save it and set the appropriate permissions, then start the openvpn daemon. There are a few other useful commands as well.
