errornointernet / openheimer

An open-source remake of the Copenheimer project. Scan the entire internet for exposed Minecraft servers!

Hi, I'm Ryan 👋

Just your average programmer.

Some statistics 📈

openheimer's Issues

Rewrite it in Rust™️

• A maximum of 16,000 IPs per second is kinda slow, should be theoretically unlimited with TCP SYN packets
• Having 300k files in a single folder is hard to search and organize
• Lower resource usage

Resume openheimer

Make a switch so you can continue open heimer where you left it

IP range exclusion

The following IP ranges are generally not going to host a minecraft server with the exception of overlay networks using a private range, and should be ignored by default.

Scanning literally everything is a great way to get blackholed off the internet.

There is no documentation on how to use OpenHeimer

There is not documentation how to use openheimer
It would be useful to explain how to install/use it

[Suggestions] QOL features

I understand most or all of these features probably won't be added until after rewriting the program in Rust or later if they are added, but I think these would be great features for later on:

• Being able to provide a minecraft account's details so Openheimer can use it to send log-in packets and check if a server is whitelisted, and possibly find other information, including what mods or plugins are used on a server, and information on the server's spawn. I don't know if this would require having a minecraft instance open on the machine running copenheimer, but it might, and if so the best option would probably be to use a fabric instance running a re-auth mod and the mods MultiConnect and ViaVersion, so the Account can re-login if it expires, and it can join servers on nearly every minecraft version.

• Save other information about serves besides IP (MOTD, server version/brand, players online, and whether or not its whitelisted, which would require the first suggestion to be added)

• an option periodically scan the internet for new servers with a configurable delay, and also periodically ping every server that's already been found with a configurable delay and update the file/database with any new info

• Possibly a barebones fabric mod that can be provided with either a file path or link to whatever database Openheimer stores IPs in, and will display and ping all the IPs in a custom secondary server list, preferably with filter options for whitelisted/not, players online, server version, server brand, and a refresh button if it connects to a database.

This would bring the featureset of Openheimer much closer to Copenheimer, however the last suggestion isn't really a suggestion for Openheimer since it's basically just a suggestion to make a separate program, though it would be useful.

Exporting IP list

add ips to a txt file so it would be easier to copy them

The IP address on line 1 is invalid!

I have a file that consist ips from masscan that looks like this:
111.111.111.111
222.222.222.222
(has 3.5 million ip addresses)
but when I try to use -ipFile ips.txt, it returns this error:
The IP address on line 1 is invalid!
Which format should I use? I even tried masscan default format which is:
open tcp 25565 xx.xx.xx.xx 1680825136
still, no luck
