# A highly non-scalable CGI DNS-over-HTTPS proxy in Bash. Have fun.

# Here's an endpoint running this script: https://doh.team-frickel.de

# Relevant Firefox settings:
# network.trr.mode = 2 -> DoH and fall back to DNS (default)
# network.trr.mode = 3 -> DoH only -> MUST use bootstrapAddress
# network.trr.uri = https://doh.team-frickel.de

Informatic

1. Format your storage
2. Configure networking (it's easiest with LuCI, or just take a look at OpenWRT howtos)
3. Configure /storage by adding proper options in /etc/config/fstab, or, again, just clicking around in LuCI
4. opkg update && opkg install tor
5. Copy proper configuration, namely /etc/tor/torrc and /etc/config/uhttpd
6. Reboot (or /etc/init.d/uhttpd restart && /etc/init.d/tor restart)
7. Check /etc/tor/hidden_service/hostname for your public .onion address
8. ...
9. PROFIT!

My OS X “VPN only” Setup For #30C3

You should never let passwords or private data be transmitted over an untrusted network (your neighbor’s, the one at Starbucks or the company) anyway, but on a hacker congress like the #30C3, this rule is almost vital.

Hackers get bored easily, and when they’re bored, they’re starting to look for things to play with. And a network with several thousand connected users is certainly an interesting thing to play with. Some of them might start intercepting the data on the network or do other nasty things with the packets that they can get.

If these packets are encrypted, messing with them is much harder (but not impossible! – see the end of this article). So you want your packets to be always encrypted. And the best way to do that is by using a VPN.
