For some context, I'm a cybersecurity engineering student. I saw a YouTube video demonstrating how to hack a $5 TEMU router and thought to myself, "What if I could run Minecraft on it?" After some research, I eventually discovered a Minecraft server written in C called Bareiron. After compiling Bareiron for the router platform, I copied it to the router and was successfully able to host a working multiplayer Minecraft server on a TEMU router.

Fast forward to a few months later and I see another YouTube video, a hoax/parody about a team struggling to port Minecraft to an AT&T router. Apparently it was a pretty popular meme for some time in early 2026 and I had no idea it even existed, but I realized that my project was able to fulfill the sudden desire for a router version of Minecraft.

I hope more people port BareIron to other niche platforms (a native homebrew Nintendo Wii server would be very cool!) but in the meantime, you can check out my GitHub page to download the project here:

I’ve ported Retrogen to Minecraft Fabric 26.2.

Retrogen is a server-side mod that lets you run selected placed features, such as new ores, in already generated chunks. It tracks every migration pass per dimension and chunk to prevent duplicate generation.

Features include: - Exact feature filtering - Dry-run mode - Persistent duplicate protection - Crash and failure recovery - /retrogen status, retry and clear commands - No client-side installation required

The mod has been tested on a dedicated Fabric 26.2 server with Overworld and Nether features.

GitHub: https://github.com/0n113/retrogen

AI disclosure: AI-assisted development tools were used during the porting, implementation, documentation, and testing process. The resulting code was manually reviewed and tested on a dedicated server.

Feedback and real-world testing are welcome. Please back up your world before using any retrogen mod.

Around half a year ago I set up an on-demand Minecraft server for a uni club I'm in by having a discord bot communicate with an AWS lambda which then turned on an AWS instance with a minecraft server (that also shuts itself off automatically after no players are active). Basically means u can just turn on a minecraft server via discord.

One of my friends recently was asking about it, so I decided to just make something simple for people to follow along. https://github.com/jiru-shan/AWS_Discord_MC_Server here is the link, it takes around 20 to 30 minutes to setup & you just need a Discord account and an AWS account and then you have a minecraft server that can be scaled to player count and is on-demand (this is mostly for smaller-scale minecraft servers tbh cuz if not you'd just have it on all the time & there r probs more efficient ways to scale to really large player counts).

DISCLAIMER: While I did code/set up all the original AWS components of this project myself the first time, I am not an avid user of terraform, so a large chunk of the terraform instructions (as well as the documentation and a good chunk of the test cases, since I was a bit lazy, though I have read the documentation & thoroughly tested the repository & instructions) are AI generated.

Additionally, depending on your plan, AWS can charge you real money if things are not working properly (no exorbitant numbers, since its just running a lambda & an ec2 instance, but you could get overcharged for a server being up for too long and not shutting itself off automatically, which you can check with /status and the AWS console). While I have tested the instructions from scratch several times and have not confirmed any errors (particularly ones that would lead to excess billing), I would recommend starting from the AWS FREE TIER (which is suitable for running ~5-7 players). The free tier also comes with credits of $100 (or $200 if u complete some basic AWS challenges) that you cannot spend more than until upgrading, which should last you the length of the free tier (half a year). Free tier means you can see if anything breaks essentially. The free tier credits also apply to non free tier instances once you upgrade so with $200 in credits u can actually go quite a while for free playing modded and stuff. Also its pretty easy to create multiple AWS free tier accounts if you have multiple payment methods & the worlds are easily transferable.

Technical Stuff: The server is hosted through Fabric and comes with several plugins (which can be configured as well if you follow instructions). The only ones that the server is shipped with right now are server-side optimization plugins. Content mods are also supported. If you have some amount of technical knowledge, it is also quite easy to log in to the server itself and make any changes you want by using the AWS dashboard and then just using regular bash. There also should be config options for almost everything (how long it takes for people to time out, built in server ops/whitelists, though you can op yourself through this and then whitelist players on the server in game, whether the discord bot pings you when the server goes down, etc, etc). Some of these config options only apply if you set them on first boot but those are mentioned on the front page of the readme & there's also a separate document dedicated to changing/upgrading stuff, including making manual changes yourself without having them get reset accidentally.

In terms of price optimization you can also save like a few bucks a month (if you're trying to max free tier money) by using Route53 with a domain (i used a subdomain of my club) instead of paying for Elastic IP addresses. This is explained in the docs but basically AWS instances change IP each reload so either you can pay money to give yourself a permanent one (Elastic IP) or set it up so that on boot of the instance it reassigns the IP the domain is pointing to to your new IP. If you already want your server to have a domain then you should be doing this since paying for both the domain and having that domain point to an elastic IP is kinda pointless (there is just a config option for this follow instructions). This also has the added benefit of making it so its unlikely your server gets scanned by bots, and, even if it does, they won't have records of it once it gets turned on and off (IP changing on each boot).

I would not recommend this for large scale servers (you'll always have a player online anyway). Also, if you have any issues/have feedback/suggested changes feel free to reply here or open an issue on github.

I got a very good deal on a r640 with dual 6140's and 96 gigs of ram.I have an Samsung 990 nvme hooked up and I'm wondering if it will be smooth since I have to get it ready for playing in the next week or so?

Our network got hit by a JAR infector between Feb and Aug 2026. We couldn't find any public writeup of it, and we know of five affected German networks — all found independently. So here's everything.

Full technical detail with IoCs: https://gist.github.com/Plattio/d40f53c2e9f962746f3c01a1a244b9e4

How to check, 30 seconds:

find /path/to/server -name "*$(printf '\xe2\x80\x8b')" -ls

That looks for files with an invisible zero-width space appended to the name. The malware hides its encrypted payload in your logs folder, named like a rotated log file. If that returns anything, you're infected.

Why the usual cleanup doesn't work:

• grep on a .jar finds nothing — classes are compressed, strings are base64'd
• the injected method is flagged synthetic+bridge, so decompilers hide it and the source looks clean
• persistence is in ./logs, so replacing every plugin doesn't touch it
• blocking the domain doesn't help, there's a local fallback that loads from that cache file
• our server jar was infected too, with a different injection style than the plugins

If you find it: don't just delete. The cache file is the only way to get the second stage, and it's evidence. Rotate every credential — assume anything the server process could read is gone.

We decrypted stage 2. It's disguised as a fake "DataFixerUpper" plugin, 6.4 MB of legit libraries as padding around one 14 KB class that's Zelix-obfuscated. So we know what gets loaded but still not what it does.

Happy to answer questions.

So, recently, I wanted to set up a self hosted server. I got 3 paper servers working and a velocity fronted to connect to them. However, I want to be able to share it with anyone. Do I just port forward, or what? I need it to be free though and I want to be able to use simple voice chat as well.

Hello so I have been working on a pvp server with my friend for these past few days. The kb is good, there is no lag as only 2 of us are online and everything is fine. I noticed that my hireg changes and that sometimes I am beating him badly while other times its horrible and very delayed. This happens to mutliple people on multiple servers and I think its an issue with Minecraft/java code or server plugins like paper. I want to fix this for my server so my kb and hitreg dont randomly change. Anyone that can help?

Hey! I have established that the GC is causing my server to suffer from extreme lag spikes. Was wondering if there is any glaringly obvious issues. Thankyou!

I have a server from an old PC that I really just put in a corner and remote into with Teamviewer, but at some point it just started closing my minecraft server when Teamviewer disconnects. It doesn't turn off the PC, I can remote back in and still see the folder left open, but the server process itself just shuts down. The logs show just a hard cut-off like it was forcefully stopped. I suspect it's related to not having any other monitor connected to it so it could be some kind of sleep mode or newish inactivity detection coming from windows. I've been meaning to set up a dual boot linux OS on it at some point anyways but in the meantime (windows has been giving me a ton of headaches, but I don't have a spare hard drive to backup everything which is a whole other issue) does anyone know if there is a way to prevent this?

I help with a server but mostly player management side so not very knowledgeable on how to impliment features, we have new players joining and as they explore the wilderness we want to have a little bit of text saying where they are, wilderness, town, nation and dungeon names.

Is there a plugin or can it be hardcoded in?

(Java 1.21.4 )

to clarify in the post forwarding

i put my IPv4 as tue internal host

internal port number 25565--25565

external port number 25565--25565

every Java and Minecraft are allowed through the firewall as well as manual added Java and Java

is there anything I may have missed?

I had a shockbyte server ages ago that I made a backup of when I closed it. I want to start it up again

1. Is it possible/safe to do such a huge update? I will have a backup just in case but will it effect the building thats already been done?

2. How does the updated world generation work? Will all of the already explored chunks keep the old world layout while all the newly generated areas will have the updated world gen?

Our 7 year old son has really gotten into Minecraft as of late so I decided to build out a vanilla bedrock Minecraft server so his friends can all play from their gaming consoles and iPads. It was working and as of today now says it needs to be updated.

I am hitting road bumps on how to update it and haven’t found a video yet that can show me how to do it.

Does anyone have any video recommendations or other tips and tricks on how to update?

On another note should I abandon this bedrock one as it’s not really been played on and build out the Java one I built the first time.

Server runs 25 gigs memory, and has a AMD Ryzen 9 9900X 12-Core Processor, im fairly certain that hardware is not the issue

Asked here last time. Things im very aware of:

1. I know entities cause lag, we've implemented stricter incontrol settings to reduce the amount significantly, have a ever 15 min clear item command set to auto run, and have been dealing with an issue where kelp has spawned on sand blocks that fall, causing lag sometimes.

2. I know chunks cause lag, we have tried to deal with this through lowering sim and render, but the amount and math on it do NOT line up, if anyone has suggestion on bringing the number down that DO NOT INVOLVE JUST LOWERING RENDER OR SIM DISTANCE, please let me know (im setting up servercore to do so automatically when performance reaches a certain point)

3. One of our previous problems was a addon called Blazes advancement pack, it has been removed.

If anyone has suggestions, please comment, even minor suggestions are welcome

Hello Minecraft server admins! (If this is the wrong place to reach the server admins, please let me know where I should go!)

I'm setting up a server via Minekeep's free tier. They use Geyser to allow Bedrock players to join the same Java server as Java players. I've turned on the whitelist and successfully whitelisted a Bedrock-only player as well as the Java Usernames of a few other players.

Now I want to whitelist my own Bedrock Gamertag so I can log in from Bedrock. This is where I run into trouble. Using /whitelist add .GamerTag where "GamerTag" is replaced with my Gamertag as it appears in my Xbox profile returns these errors:

[08:26:46 WARN] Couldn't find profile with name: .GamerTag
[08:26:46 INFO] That player does not exist

I've seen people have this problem adding Bedrock players, but always Bedrock-only players. Since I have successfully added a Bedrock-only player, I don't think that is my problem.

To cover all the bases, I've tried logging in using Bedrock after my Java Username was successfully whitelisted, but I get the message that I'm not whitelisted. I've also tried whitelisting my XUID, updating the whitelist.json file manually, and restarting everything several times.

Can anyone help? Has anyone else run into this? Do I need to replace the vanilla whitelist with a plugin?

Any help is greatly appreciated!

for a long time I want to create a server in my house to host without having to pay (only the cost of electricity and internet), the problem is that I am deciding which equipment to buy.

Find a good price Dell Optiplex D15U with an intel i5 13500T, 16 gb of DDR4 ram and a 256 SSD, I feel that these specifications are good and I would like to buy it, but I am still undecided.

My requirements are mainly for servers with mods or vanilla with enough people (taking advantage of the fact that I could probably make several dockers to host two servers at once) but I don’t know if these specifications are good or would recommend other types of processors. Thank you very much!

I run a Minecraft server with economy, nations, wars, PvP, lands, jobs, and quests. Over the past months I've tried several things to make it feel less generic — a player-run tribunal system (players hated it, dropped it), a ranking/ELO system for nation wars (already live), a proposed prestige reset each season (players voted it down).

Despite that, players still say it feels "like every other server." I'm not looking for a list of features to add — I've been down that road. What I'm trying to understand from other admins who've dealt with this:

• When you've seen a server actually break out of feeling generic, was it a mechanic, or something about how it was run/communicated?
• Has a specific system you built ever gotten voted down or rejected by your playerbase the way mine has? What did you learn from that?

Sharing what worked (or didn't) on your own server would help a lot.

Hello!
I recently wanted to self host a Minecraft server again for my friends but unlike the last times I've done it I can't seem to connect to it outside of the machine actively hosting it. Even on a laptop on the same network I can't seem to connect to it.

So far I have

-Port forwarded 25565 on both TCP and UDP

-Added Windows Firewall rules to allow connections to and from port 25565

-Tried hosting a regular LAN world (still couldn't connect on the same network)

-Restarting both my computer and router

I have self hosted in the past with barely any problems and can't seem to find what the issue could even be this time

Edit: we are so barrack, all I did was configure the windows firewall settings for Java instances

[26.2 Modded Fabric Server]
I'm hosting a server for my Family currently and have encountered a small issue that made me and my siblings crash and be unable to join back to the server

I could tell from the logs that Voice chat was the main suspect and when launching the server without we were able to play the rest of the night without issue

however playing with Voice chat is something I really want to get working/fix for the server and so any help in finding what caused the issue would be very appreciated

Here is the two logs showing the same voice chat issue to the crash

https://mclo.gs/itpfNzl

And here is the server config for my Voice-chat mod (I'm using playit to connect the server to my siblings network)

I want to assign a command to open daily rewards menu (/daily) to an enderchest in my paper server, how would I make that happen?

Similarly how NPCs plugin work, I want to make it happen with blocks

We have a 26.2 PaperMC SMP server, members are complaining why their portal-based farms not working. I found this plugin called Otherside but it doesn't work on 26.2. Do you guys know any plugin similar to this? or any workaround?

Hello everyone,

I have been playing ATM10 and highly enjoying it. I went from hosting on my own PC to renting one so that it could be on all of the time, allowing friends to join, but of course all server hosts tend to be pretty bad and it just lags under very little load.

So this is where I would like to buy my own dedicated hardware. What are some minimum specs I should be looking for. I've got some ideas, such as R7 and, preferably, 32GB of DDR5 and an NVME. Are there any good prebuilt brands or would I be better off buying something from eBay? I'd like to stick to around $500 but don't mind going over a few hundred dollars if it would really give me what I am wanting.

Also, would an X3D chip give much benefit?

Hi! I've got a fabric server with geyser MC installed and I really need a server side ping reporter for the latest Minecraft version. Did you know any good one?
