Re: Headless server doesn't detect NAT with port randomization correctly

So if I read you correctly, you want to host your server behind NAT? I just looked up in factorio wiki about headless servers, and they require to have public IP. I also looked at history of this article and change regarding headless servers having public IP was made on 19 of March 2017, more then ...

Re: Headless server doesn't detect NAT with port randomization correctly

So I wrote a program to test if my NAT can be punched correctly and in fact it can. Here's the code: https://github.com/rkfg/nat_punch How to test: 1) Run server.py on a VPS with a WAN IP (it accepts -p flag to set the port but you can leave it as is): python3 server.py 2) You can run server.py on m...

Re: Headless server doesn't detect NAT with port randomization correctly

Guys, what happened with It's never what you think it is ? Recently we had a bug report where a modded game would freeze for a minute for seemingly no reason and then continue like nothing went wrong. It being a heavily modded game my first reaction was to blame it on the mods doing something in a v...

Re: Headless server doesn't detect NAT with port randomization correctly

I get that but can you help me to debug this issue? I can provide network dumps from tcpdump or any other info you might need. I'm a devops at work and I know how to configure iptables and routing so I doubt it's on my side. I'm not saying it's a bug on your side either but... who knows? If you're w...

Re: Headless server doesn't detect NAT with port randomization correctly

Okay, but why do I see the address replies that come from your servers and absolutely nothing from them when I try to connect to my game from the client that I launch from Steam? Should your servers somehow respond to the ping packets that the headless server sends their way? Because I don't see tha...

Re: Headless server doesn't detect NAT with port randomization correctly

Any thoughts? I'd like to be able to host a game on my home PC but currently I'm limited to forwarding ports using my VPN provider, it works but the ping time is much higher than it could be and there's also a noticeable packet loss because the VPN server is in another country. Just from the traffic...

Headless server doesn't detect NAT with port randomization correctly

I tried to host a server behind two NATs, the router and ISP ones. Pingpong servers replied with my external address and port and I thought it was okay but I couldn't connect to my own server via Internet neither could another player. So I started digging. I use Debian testing amd64 as my only OS + ...

Re: Friday Facts #260 - New fluid system

I agree on the model, but Dijkstra algorithm can not be used to solve this problem. Each algorithm can solve a specific problem, if you try to take one algorithm and put it on another problem, you have no guarantee it will work and chances are, you are missing on an algorithm that has been crafted ...

Re: Friday Facts #259 - Scan-codes, Prototype IDs, HR worm

Forcing undo as Ctrl+key-right-to-left-shift works for the opposite, increasing the number of people who will rebind. What makes you think that? Because under the current proposition for Ctrl+Z, it's the A Z ERTY users that will be forced to rebind (away from it), due to the issue raised in the FFF...

Re: Friday Facts #259 - Scan-codes, Prototype IDs, HR worm

So, basically, "fuck you newer people, we (older people) are going to keep using what we're used to, even if it's worse" ? Well, not that extreme. It's just that if people are used to some shortcut already it's easier for them to use it further in other games and apps. And if some people think they...

Re: Friday Facts #259 - Scan-codes, Prototype IDs, HR worm

Cutemine, rkfg, that's my point : doing the right thing often presumes to go against what people are used to ! Well, that boils down to the definition of "right". It's like forcing people to use HJKL for movement instead of WASD because Vim use them and it's a "right" thing to do and also muh effec...

Re: Friday Facts #259 - Scan-codes, Prototype IDs, HR worm

I think this is really the right thing but people with non-US layouts might have got used to those shortcuts in other apps. Is Ctrl+Z actually Ctrl+W in MS Word, for example? What about browsers? Ctrl+W usually closes the active tab, is it Ctrl+Z for the French layout? It's kinda controversial for t...

Re: Friday Facts #247 - Pricing and its exploits

There are region locks on Steam that prevent this reselling scam. It's used for many not so cheap games, usually the keys bought in CIS can only be activated in CIS. But if GOG can't sell per-region keys that wouldn't work. The rouble price dropped noticeably a couple of months ago so that would mea...

Re: Friday Facts #230 - Engine modernisation

Vulkan would really help with parallel renderer, something that Factorio might not even need. It's not CPU-intensive on the graphics front from what I saw and read, the world updates eat most of the CPU. Vulkan allows to load all the cores when you prepare and fill the GPU buffers (commands, vertexe...

The terrain on the cliff must be different, not just a continuation of the "lower" part.

I love these changes, please implement them. However, if you need some feedback about GUI, I'd complain about blueprints. It's truly a mess right now, it's functional but very counterintuitive compared to the previous UX. So, to create a blueprint (a basic and quite regular task) I have to press a h...

You can bring steam with a train from the base and there's a lot of steam when using nuclear power. Not really a problem.
