nwlyoc 16 Posted ... (edited) 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.UPDATE: A new version which uses Hummingbird and has been improved in many aspects (including automatic connection at boot) can be found here. #!/bin/bash # an interactive shell script to control the command line version of the AirVPN Eddie client and openconnect more comfortably PROFILE_PATH="$HOME/.airvpn/default.xml" API_KEY="<your api key>" DIALOG_OK=0 DIALOG_CANCEL=1 DIALOG_EXTRA=3 DIALOG_ESC=255 HEIGHT=0 WIDTH=0 BACKTITLE="VPN Control" FORMAT="text" URL="https://airvpn.org/api/" PID=$$ function check_sudo { # check if user has sudo privileges sudo -vn &> /dev/null # gain sudo privileges for commands that need it (better than running everything with sudo) if [ $? = "1" ] then unset EXIT_STATUS_SUDO PASS_PROMPT="Establishing VPN connections and changing network traffic rules requires root privileges.

OpenSourcerer 1435 Posted ... This is fantastic! Holy hell, the community really is awesome around here 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. I'm up for some testing on Debian and I'll let you know if there's something that needs to be done to make it work there, if at all. 1 smith_wesson reacted to this Quote Hide OpenSourcerer's signature Hide all signatures NOT AN AIRVPN TEAM MEMBER.

nwlyoc 16 Posted ... Thank you! I believe the syntax for iptable rules is identical, it's just the first half of the commands that needs to be exchanged. Let me know if it works! 1 smith_wesson reacted to this Quote Share this post Link to post
rok1 1 Posted ... Is this ready for use on Ubuntu/Debian distributions? I've been clamoring to build a low power embedded Deluge box with VPN only internet access. I have no need for a window manager so I am all about the command line. 1 smith_wesson reacted to this Quote Share this post Link to post
nwlyoc 16 Posted ... Please try! I don't see why it shouldn't work on Debian based distros since there is no distro specific stuff in there except the default network lock which relies on firewalld, but as discussed above, it should only be a small adjustment to change it to iptables if you care about that feature. I have a lot of work at the moment, so I can't test it myself or make further improvements, but I've fixed some minor stuff last week and it's still working very well for me, using it all day. Just make sure you have the tools installed that are listed above (most likely installed by default) and you should be fine. If you choose to try it out, let me know in case there are any problems!
