Hi L.R. D.S., Stating your opinion on a controversial topic and announcing to leave the list in the same message feels like someone shouting their opinion into a room full of people and slamming the door from the outside before anyone can react. Also, doing so after someone pointed out to you why your criticism was probably unjustified makes this behavior even more sad, I'd say.
I'm sure nobody here thinks that criticism has to be perfect, and I also don't think that - even after your first angry reaction - a calm, objective explanation of the reasons for the criticized current behavior is "dodging" at all. About the PS, Tails already makes use of iptables to prevent (nearly) any non-Tor traffic from happening. However, using a firewall to block specific web pages will probably not work in the way you might expect it to do - if there is the legitimate site http://example.org/information, and the advertisement banner http://example.org/advertisement.png, then you can't remove that banner by denying access to the IP behind example.org. As far as I know, you could, if the traffic is unencrypted (fails for Tor and even HTTPS itself), use some special iptables rules to intercept all text and block connections that contain what you're looking for. Add 1000 of these rules, and network performance becomes horrible, I guess. DNS solutions additionally fail whenever advertisement hosts are referenced using their IP address instead of their hostname. http://192.0.2.1/advertisement.png evades DNS solutions. For Tails/Tor specifically, there's another huge problem with your suggestion: DNS lookups are performed by the exit node, not your own computer. Else, your DNS provider could easily see which hostnames you look up, breaking anonymity. Connections in general are not made directly to the web hosts, but instead to the Tor entry node, which forwards your request. The only place to implement firewall/DNS adblocking would be the exit node, not the computer running Tails. I'm pretty sure you don't want the exit node operator to decide which hosts you and all other Tor users are allowed to connect to. ;D Without any "dodging" at all, I hope, this explains why neither firewall nor DNS solutions can be "more effective and efficient" than a browser addon for blocking advertisements on web pages. After all, use cases like this one are what browser addons exist for. Have a nice day, and feel free to come back whenever you want to. ^.^ Best regards, Tobias Frei [just yet another guest; not an official list admin statement or whatever it might look like.] Am 17.05.2015 um 01:42 schrieb L.R.
