    Hey all! I ran into an issue the other day when setting up AirVPN where I found alot of the AirVPN IP's appear to be blocked by my ISP. In my quest to resolve this issue, I ended up creating a script that uses fping and dig to get all the IPs for a region, check that they work, and add those to your AirVPN configuration. I figured this script might be helpful to some, so I'd share it here. You can download it here: https://gist.github.com/zikeji/144247cb20793a5a7c65653e5f7c572b A simple one line to download it and set the executable bit: wget https://gist.githubusercontent.com/zikeji/144247cb20793a5a7c65653e5f7c572b/raw/a414cc4f6828904992f18e0a0bdecf6cf5e4f85c/airvpn_remotes.sh -q -O airvpn_remotes.sh && chmod +x airvpn_remotes.sh Warning: Remember, for your safety ALWAYS review a downloaded script before executing it! The command's help output: airvpn_remotes.sh Description: Use dig and fping generate multiple remotes for an AirVPN config, replacing existing remote(s), and ignoring IPs that aren't responding. Remotes are placed in order of lowest ping to highest. Usage: airvpn_remotes.sh [--port=<int>] [--query=<fqdn>] [--ipv4] [--ipv6] [--remote-random] [--in-place] [input-file] airvpn_remotes.sh -h | --help Options: -h, --help Show this screen. -p <int>, --port=<fqdn> Override the port supplied on each remote line [default: 443]. -q <fqdn>, --query=<fqdn> Supply the DNS record you wish to query to use the IPs from [default: ca.all.vpn.airdns.org]. -s <ns>, --server=<ns> The name server you wish to query the records against [default: ns1.airvpn.org]. -c <int>, --count=<int> Change the amount of pings ran by fping for more accurate ping sorting [default: 4]. -4, --ipv4 Only query IPv4. -6, --ipv6 Only query IPv6. -r, --remote-random Add remote-random to the AirVPN config (this will cause OpenVPN to randomize the server order when connecting). -i<ext>, --in-place=<ext> Edit the file in place (makes backup if extension supplied), ignored if no input file is supplied. The first non-option argument is the name of the input file; if no input file is specified, then the standard input is read. All other non-option arguments after the first are ignored. You'll need to ensure dig and fping are installed on your distribution before you can use it. Additionally, if your system doesn't support IPv6 it'll only return IPv4 be default (because naturally pinging the IPv6 addresses will fail). And finally, I've only tested the script on Ubuntu 20.04, but hopefully you don't run into trouble. By default the script checks the DNS record AirVPN maintains for all of CA's servers. You can find out more about the records option here: https://airvpn.org/faq/servers_ip/ The help file should be pretty clear as to how to use the script, but I'll provide an example. I want to update my AirVPN.ovpn file with new remotes that'll be executed randomly and only include IPv4 remotes, and I want them from the Netherlands. Additionally, instead of connecting in order I want it to connect to a random server defined in the config. Since I use port 1194 instead of port 443, I also want each remote to use port 1194 instead of the default. I also want it to backup my original config before overwriting it. I would run: ./airvpn_remotes.sh -r4 -qnl.all.vpn.airdns.org -p1194 -iold AirVPN.ovpn Which would remove any lines from my AirVPN conf that are a remote or a remote-random and add the new remotes, sorted by lowest ping first (which is irrelevant because we're also adding remote-random). Hopefully this script might be useful for someone else as well!
