dragnpkgs

this is my personal nixos modules and packages repository. while it was designed for my own use, it's also intended to be flexible and reusable enough for general purpose usage. i might consider upstreaming into nixpkgs if there is sufficient interest

usage

dragnpkgs provides a set of nixos modules and a nixpkgs overlay containing custom packages (automatically applied). to use, import the top-level module into your system configuration, eg

{config, lib, pkgs, ...}:
{
  imports = [
    path/to/dragnpkgs
  ];
}

alternatively, add it as a nix channel

nix-channel --add https://git.lain.faith/haskal/dragnpkgs/archive/main.tar.gz dragnpkgs

then in system config

{config, lib, pkgs, ...}:
{
  imports = [
    <dragnpkgs>
  ];
}

for standalone nix on other distros, use ~/.config/nixpkgs/overlays.nix to enable the dragnpkgs overlay

(import <dragnpkgs> {}).nixpkgs.overlays

options documentation

documentation for options provided by dragnpkgs

services.ghidra-server

the shared project server for ghidra

example usage:

services.ghidra-server = {
  enable = true;
  host = "your.domain.or.ip";
};

services.ghidra-server.enable

enables the ghidra server service

services.ghidra-server.enableAdminCli

adds a system package for the CLI tool ghidra-svrAdmin, which allows anyone in the ghidra group to administer the server (this corresponds to the server/svrAdmin tool in the stock ghidra distribution)

services.ghidra-server.{package, jdkPackage} (ghidra_headless, openjdk17_headless)

allows overriding the ghidra package and jdk package used for the server

services.ghidra-server.host

the server hostname or IP; this is typically required (by java RMI) for correct operation

services.ghidra-server.basePort (13100)

the server will use 3 consecutive TCP ports starting from this port

services.ghidra-server.directory (/var/lib/ghidra-server)

the root directory for server files

services.ghidra-server.{user,group} (ghidra)

the service user and group

more coming soon(tm)

packages documentation

ghidra_headless

a variant of ghidra built with a headless openjdk, intended to reduce closure size for server operation
