  Ntp is the time protocol, right?

    Yup

  Hold up, using the ntp port to skip WiFi sign in is a game changer. Any way to do that with Tailscale on iOS?

    Nice one.

    But now that you outed the secret, we just need to QoS the NTP port.

    I have no idea how to do that on tailscale as I use pivpn on a vps. It works on Norwegian airlines and SAS, but I assume other systems might block traffic differently.

      Definitely worth a bit of research to see if it’s feasible (or potentially just set up wireguard for those cases). Thanks!

  The airplane captive portals generally don’t work if you use a different DNS.

  I’ve always had to defer to “automatic” DNS and let DHCP give me the DNS address in order to access the wifi

    It is possible to use VPN over DNS. Some mad lads back in the '90s made a DNS server that would forward TCP packets over name service text records. The captive portals usually still let DNS pass. But it’s not like you’re going to be able to use any high bandwidth applications that way.

  I have all this, except the NTP port… Any advice on how to set this part up?

  • Sparky@lemmy.blahaj.zone ⁨2⁩ ⁨months⁩ ago

    I just set up the server to listen on port 123/udp(ntp). You can also try port 53 although that isn’t always reliable.

      Thanks, I saw you mention SAS. I fly with them often, I might try this out.

  Is using ntp port for WireGuard safe?

  source

  • Sparky@lemmy.blahaj.zone ⁨2⁩ ⁨months⁩ ago

    If you call security trough obscurity a security measure, then it’s really safe. Bots scanning for wireguard servers won’t find yours because they’ll be looking for the default port. In general wireguard will only respond to wireguard traffic, so a bot trying to exploit an ntp server will see silence as wireguard will not respond to actual ntp traffic.
