It scans all the IPv4 addresses in order to find Minecraft servers exposed to the internet. The original version is currently closed-source and not available to anyone else, that's why this version exists.\n\n:rocket: Capable of scanning up to \u003cb\u003e16,000 IP addresses per second\u003c/b\u003e, finishing everything in just 3 days! :rocket:\n\n## Installation\n\nIn order to use the current version of openheimer, you must compile from source.\n\n### Requirements\n- git (or download the tarball/zip)\n- [go](https://go.dev/dl/)\n\nIn your terminal,\n\n```shell\n$ # Not necessary with tarball/zip\n$ git clone https://github.com/ErrorNoInternet/openheimer.git\n\n$ cd openheimer\n$ go build\n```\n\nYou should now have an executable in the same directory.\n\n## Usage\nRun `openheimer -help` to see a list of commands\n```\nUsage of ./openheimer:\n  -database string\n        The database to store the results in (default \"openheimer.db\")\n  -ipFile string\n        The file to extract IP addresses from\n  -logFile string\n        The file to store the logs in (default \"openheimer.log\")\n  -maxPingWorkers int\n        The maximum amount of workers to ping IPs (default 4000)\n  -maxScanWorkers int\n        The maximum amount of workers to scan IPs (default 1000)\n  -startingIP string\n        The IP address to start scanning from (default \"1.0.0.0\")\n  -timeout int\n        The amount of seconds to wait before timing out (default 5)\n  -verbose\n        Display everything that's happening\n  -version\n        Display the current version of OpenHeimer\n```\nNote: `maxPingWorkers` are the amount of workers to use to check for open ports. `maxScanWorkers` are the amount of workers to use to check if an IP has a valid Minecraft server. Normally you would increase `maxPingWorkers` to ping IP addresses faster, but when you're scanning IP addresses from a file (produced by masscan for example), you should increase `maxScanWorkers`.\n\n\u003csub\u003eIf you would like to modify or use this repository (including its code) in your own project, please be sure to credit!\u003c/sub\u003e\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ferrornointernet%2Fopenheimer","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ferrornointernet%2Fopenheimer","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ferrornointernet%2Fopenheimer/lists"}
