Is there any privacy advantage or security concern over them ?
This is more of a philosophical question than anything. If you trust that they’re not using your data for anything nefarious, I really advocate for RethinkDNS. It’s a really great service and truly fills a need between the clear-net and running your own DNS.
If you don’t trust RethinkDNS, etc, etc, to not do anything nefarious, then it’s time to setup your own.
I always use rethinkdns and block bypassed dns, so i think now every dns is routed through rethinkdns and its impossible to cause a leak. Is that a myth as no dns app can provide that much privacy or security ?
I wouldn’t say it’s a myth or anything, but to say you’re 100% secure from leak? Probably don’t trust that feeling. Keep it at 99% secure with 1% suspicion.
How effective is an application firewall than a network level firewall like nextdns ?
Like most security software, it depends on how you use them. If you use firewalls effectively, even software based firewalls can work exceptionally well.
may i use a application firewall or network level firewall ?
You can do both. Software based requires you to setup something on each device you want to firewall. Network is a blanket and will affect all of your devices with only one setup. But either works just fine–just depends on how much effort you want to put into it, I guess.
I guess it depends on how you got caddy to begin with. If you used xcaddy, you have to update caddy the same way (recompile via
xcaddy
) otherwise you’ll get the default binary which has no misc modules by default, which kinda sounds like what’s happened but who knows for sure.If you’re feeling daring, you can try to compile
caddy
yourself withxcaddy
, it’s super easy.Save your
Caddyfile
’s (ultra important), and uninstallcaddy
. Installxcaddy
(apt install xcaddy [orgo install github.com/caddyserver/xcaddy/cmd/xcaddy@latest
]). Then usexcaddy
to compilecaddy
with the modules you need;Caddy will build and be spit out in
/tmp/caddy
. Move it to/home/username/.local/bin
or something, and make sure that directory is in your path. Don’t forget tochmod +x caddy
.Run caddy like normal and see if this fixes your issue. If not, you’ll likely have to try and older version of caddy (uninstall and specifically install the previous version or if you can’t, use
xcaddy
withCADDY_VERSION
to build a specific version with your modules), or wait until they push a fix for whatever they broke.
