Yup. A variation of the quote (basically capitalists instead of American businessmen) is commonly attributed to Lenin instead of Khrushchev. But that, too, can’t be verified and is said to be fake.

Instead of waiting for a zombie fungus to evolve into something that can infect humans, they decided to cut out the middleman and made cyborg mushrooms.
Buying a domain. There might be some free services that, similar to DuckDNS in the beginning, work reliably for now. But IMHO they are not worth the potential headaches.
DuckDNS pretty often has problems and fails to propagate properly. It’s not very good, especially with frequent IP changes.
Damn, that’s wild. Cheers for sharing!
I have an understanding of the underlying concepts. I’m mostly interested in the war driving. War driving, at least in my understanding, implies that someone, a state agency in this case, physically went to the very specific location of the suspect, penetrated their (wireless) network and therefore executed a successful traffic correlation attack.
I’m interested in how they got their suspects narrowed down that drastically in the first place. Traffic correlation attacks, at least in my experience, usually happen in a WAN context, not LAN, for example with the help of ISPs.
Sounds interesting, got any links for further reading on that?
I can’t quite connect the dots between wifi/internet traffic spikes when IRC is so light on traffic that it’s basically background noise and war driving.
Nice message, but the thought of the existence of a competitive scene of contractors specializing in mounting TVs is hilarious. Also, that mounting plate is crooked af.
Windows, as any operating system, is best run in a context most useful to the user and appropriate for the user’s technical level.
I wrote a simple, locally running Webapp some time ago, that targets the Lemmy Import-/Export-API and supports transferring only specific userdata between accounts, as demonstrated in this corresponding Wiki Entry.
The import functionality in Lemmy is additive in nature, meaning anything you import gets added on top of existing settings instead of replacing it.
Does the same thing as these manual instructions for this usecase, may be helpful to some.
I’d appreciate it very much!
Great suggestion to secure the backups themselfes, but I’m more concerned about the impact an attacker on my network might have on the external network and vice versa.
That’d be the gold standard. Unfortunately, the external network utilizes infrastructure that doesn’t support specifying firewall rules on the existing separate VLAN, so all rules would have to be applied on the Pi itself or on yet another device between, which is something I’d like to avoid. Great general advice, though!
While this is a great approach for any business hosting mission critical or user facing ressources, it is WAY overkill for a basic selfhosted setup involving family and friends.
For this to make sense, you need to have access to 3 different physical locations with their own ISPs or rent 3 different VPS.
Assuming one would use only 1 data drive + an equal parity drive, now we’re talking about 6 drives with the total usable capacity of one. If one decides to use fewer drives and link your nodes to one or two data drives (remotely), I/O and latency becomes an issue and you effectively introduced more points of failure than before.
Not even talking about the massive increase in initial and running costs as well as administrive headaches, this isn’t worth it for basically anyone.
This photo may have (unfortunately) won him the race.

Ew.
I’ve been tempted by Tailscale a few times before, but I don’t want to depend on their proprietary clients and control server. The latter could be solved by selfhosting Headscale, but at this point I figure that going for a basic Wireguard setup is probably easier to maintain.
I’d like to have a look at your rules setup, I’m especially curious if/how you approached the event of the commercial VPN Wireguard tunnel(s) on your exit node(s) going down, which depending on the setup may send requests meant to go through the commercial VPN through your VPS exit node.
Personally, I ended up with two Wireguard containers in the target LAN, a wireguard-server and a **wireguard-client **container.
They both share a docker network with a specific subnet {DOCKER_SUBNET} and wireguard-client has a static IP {WG_CLIENT_IP} in that subnet.
The wireguard-client has a slightly altered standard config to establish a tunnel to an external endpoint, a commercial VPN in this case:
[Interface]
PrivateKey = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
Address = XXXXXXXXXXXXXXXXXXX
PostUp = iptables -t nat -A POSTROUTING -o wg+ -j MASQUERADE
PreDown = iptables -t nat -D POSTROUTING -o wg+ -j MASQUERADE
PostUp = iptables -I OUTPUT ! -o %i -m mark ! --mark $(wg show %i fwmark) -m addrtype ! --dst-type LOCAL -j REJECT && ip6tables -I OUTPUT ! -o %i -m mark ! --mark $(wg show %i fwmark) -m addrtype ! --dst-type LOCAL -j REJECT
PreDown = iptables -D OUTPUT ! -o %i -m mark ! --mark $(wg show %i fwmark) -m addrtype ! --dst-type LOCAL -j REJECT && ip6tables -D OUTPUT ! -o %i -m mark ! --mark $(wg show %i fwmark) -m addrtype ! --dst-type LOCAL -j REJECT
[Peer]
PublicKey = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

where
PostUp = iptables -t nat -A POSTROUTING -o wg+ -j MASQUERADE
PreDown = iptables -t nat -D POSTROUTING -o wg+ -j MASQUERADE
are responsible for properly routing traffic coming in from outside the container and
PostUp = iptables -I OUTPUT ! -o %i -m mark ! --mark $(wg show %i fwmark) -m addrtype ! --dst-type LOCAL -j REJECT && ip6tables -I OUTPUT ! -o %i -m mark ! --mark $(wg show %i fwmark) -m addrtype ! --dst-type LOCAL -j REJECT
PreDown = iptables -D OUTPUT ! -o %i -m mark ! --mark $(wg show %i fwmark) -m addrtype ! --dst-type LOCAL -j REJECT && ip6tables -D OUTPUT ! -o %i -m mark ! --mark $(wg show %i fwmark) -m addrtype ! --dst-type LOCAL -j REJECT
is your standard kill-switch meant to block traffic going out of any network interface except the tunnel interface in the event of the tunnel going down.
The wireguard-server container has these PostUPs and -Downs:
PostUp = iptables -A FORWARD -i %i -j ACCEPT; iptables -A FORWARD -o %i -j ACCEPT; iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
default rules that come with the template and allow for routing packets through the server tunnel
PostUp = wg set wg0 fwmark 51820
the traffic out of the tunnel interface get marked
PostUp = ip -4 route add 0.0.0.0/0 via {WG_CLIENT_IP} table 51820
add a rule to routing table 51820 for routing all packets through the wireguard-client container
PostUp = ip -4 rule add not fwmark 51820 table 51820
packets not marked should use routing table 51820
PostUp = ip -4 rule add table main suppress_prefixlength 0
respect manual rules added to main routing table
PostUp = ip route add {LAN_SUBNET} via {DOCKER_SUBNET_GATEWAY_IP} dev eth0
route packages with a destination in {LAN_SUBNET} to the actual {LAN_SUBNET} of the host
PostDown = iptables -D FORWARD -i %i -j ACCEPT; iptables -D FORWARD -o %i -j ACCEPT; iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE; ip route del {LAN_SUBNET} via {DOCKER_SUBNET_GATEWAY_IP} dev eth0
delete those rules after the tunnel goes down
PostUp = iptables -I OUTPUT ! -o %i -m mark ! --mark 0xca6c -m addrtype ! --dst-type LOCAL -j REJECT && ip6tables -I OUTPUT ! -o %i -m mark ! --mark 0xca6c -m addrtype ! --dst-type LOCAL -j REJECT
PreDown = iptables -D OUTPUT ! -o %i -m mark ! --mark 0xca6c -m addrtype ! --dst-type LOCAL -j REJECT && ip6tables -D OUTPUT ! -o %i -m mark ! --mark 0xca6c -m addrtype ! --dst-type LOCAL -j REJECT
Basically the same kill-switch as in wireguard-client, but with the mark manually substituted since the command it relied on didn’t work in my server container for some reason and AFAIK the mark actually doesn’t change.
Now do I actually need the kill-switch in wireguard-server? Is the kill-switch in wireguard-client sufficient? I’m not even sure anymore.
I simply can’t wrap my head around the thought process behind launching a clusterfuck like this. Y Combinator probably didn’t do their due diligence and simply rode the fading AI Bubble, so I can at least understand how the funding might have been approved.
But actively leaving your $250,000+/year job to team up with some questionable choices to basically fork two OS projects, change the discord links and generate an illegal licence for that shit show, all while proudly stating, publicly, “dawg i chatgpt’d the license, anyone is free to use our app for free for whatever they want. if there’s a problem with the license just lmk i’ll change it. we busy building rn can’t be bothered with legal” when they are made aware of the fact.
This is absolutely insane, sounds like someone was about to get fired and decided to use some personal relations and fresh graduates to somehow successfully cash in one last time with absolutely no regard of even the basics. Pretty wild that those guys even managed to figure out how to found a Startup. Probably asked ChatGPT for instructions there, as well.
