Specific people cannot join me, while others can.
Hi! I am making a Fabric Minecraft server that has a decently big selection of mods. Currently, I am having an issue to where certain people cannot join, while others can. I have checked my firewalls, changing ports, etc, and nothing works. They just seem to have extremely laggy/poor connections to me, but not vice versa. Does anybody have any idea what could be causing this?
What do you wish you knew when you started learning Java? (and some other questions! :D)
My dream is to run a semi-vanilla minecraft server with my own custom plugins- BUT I need to learn Java first! Im considering purchasing a few courses on Udemy but I wanted to ask around first to see if there were any particular teachers or videos or just anything that really helped you breakthrough- or if theres any starting-out advice you have that you wish you'd known when you began.
Ive also done a little bit of research and to start out im pretty sure I should run paper, but what happens if my server gets bigger? Should i be swapping? or is it just a misconception that paper is only meant for small servers? is there a better option i should be using if i intend on using quite a bit of plugins, a custom texturepack, and running events?...
entity cramming performance question
no issues at the moment, just have been incredibly curious:
which is better for performance, a single block cramming farm, or a smallish free range pen? (assuming there are the same number of entities)

Opening up my server to the public
Hey everyone, I have a server that I have been hosting on my own computer for 10+ years (it’s changed versions but the world has remained intact) now and only letting in friends and family. It is a paper server and I have a good few plugins but nothing crazy however the world is vast. I finally am in a spot where I’d like more people to be able to join. My main question is around the safest way to do so.
I would love to be able to “open the floodgate” so to speak and let people start joining and experiencing but again want to ensure on the network side I’m safe. The plugin/internal protection side I am working on getting all my permissions and anti grief zones down.
My main question is should I stick with self hosting and just “lock down” my network and server or explore a hosting option as I may need to scale off my personal computer....

Market Research
Hey there Admincraft,
I'm working on a project and we were wondering what would be the best server host name for a new company? We're looking for something that's unique and something that people will like!
The company will be hosting Minecraft servers and Discord bots, maybe more games will come in the future. ...
Players on my server can't drop items
This is kind of a weird issue but players can't drop items when they go into their inventory and press their drop key. I have checked worldguard and I have allowed item dropping. There are no errors in the console on start up so I think it's pointless to send logs but I can send them if anyone wants to see them. These are my plugin:
Paper Plugins: (2):
- FancyHolograms, TotemGuard
Bukkit Plugins: (85):...
Server crashing after I added new mods
I added around 45 new mods to my minecraft server, which can be seen in the screenshot uploaded.
But now when I launch the server and load new chunks, the server mysteriously crashes for god knows what. And I am all out of energy today to try and solve this, so please provide me with some fixes.

Nothing in fabric modding discord helps....Swapping drives in a software raid 10 array
Should I use an NVME duplicator to make 1:1 clones of the drives or would it be possible for me to just replace each drive one-by-one, because theoretically the array would just rebuild itself entirely?

Won't start on 1.21.3-82
So I have switched to "self hosting" from a machine I rent, I've never dealt with switching jars without the host just having simple installs. I have done everything I was supposed to and changed my executable and updated it and it still won't start on 1.21.3-82

Recommended Minimum Resources
Decided to roll with Prismnodes to host my server temporarily. Running Better Minecraft BMC4 for a relatively small group until I build my dedicated server.
Honestly I don't expect more than 4 players on at any given moment, but plan for about 8 that are interested in accessing at the moment. Is 8 or 10GB a reasonable amount to start with? I'm trying to stay budget conscious at the moment and not particularly wanting to pay more than I need going into a relatively short term venture....
30% cpu usage on 1.20.1 paper normal?
i have no plugins installed
CPU: AMD EPYC 9554 (4) @ 3.095GHz
OS: Ubuntu 20.04.6 LTS x86_64
RAM: 16gb ddr4...
Cpu for personal hosting
will be that big of a difference between the 4590 vs 8500, with a 15% in single thread, for a small server in linux

Better Minecraft Server Inquiry
Howdy all! Many apologies if this post comes across as trivial or under-researched on my part in advance. But I have been playing BMC4 with my spouse using the world share feature with Luna for the past 2 weeks. interest in the world has spread among our friend group and I had some questions regarding requirements for dedicated servers that I may be unaware of.
I have an Acer Aspire E15 sitting around collecting dust. I was wondering if it would be a good idea to go through the trouble of loading it up with Debian and running a dedicated server from there.
