debian11安装tcp-brutal失败解决

用sing-box作为服务端总会用到tcp-brutal,但是debian11/ubuntu20等系统安装tcp-brutal总会失败报错

error: Failed to load kernel module, kernel module might not be installed successfully.
warning: tcp-brutal is installed but failed to load.

1. 安装nix

apt install nix -y

2. 在vps你觉得好看的目录下创建文件

touch shell.nix

3. 将以下内容写入第二步创建的文件内保存

let
  nixpkgs = import (fetchTarball "https://github.com/NixOS/nixpkgs/archive/refs/tags/24.05.tar.gz") {};
  pkgs = nixpkgs.pkgs;
  lib = nixpkgs.lib;
  script = ''
    #!/usr/bin/env bash
    
    set -e
    
    LDSO="${pkgs.glibc}/lib/ld-linux-x86-64.so.2"
    RPATH="${lib.makeLibraryPath [ pkgs.glibc pkgs.elfutils ]}"
    PATCHELF="${pkgs.patchelf}/bin/patchelf"
    FILE="${pkgs.file}/bin/file"
    FIND="${pkgs.findutils}/bin/find"
    is_executable() {
      local _target="$1"
      local _mimetype="$("$FILE" --mime-type --brief "$_target")"
      [[ "$_mimetype" == "application"*"executable"* ]]
    }
    patch_kernel_dir() {
      local _dir="$1"
      echo "[info] patching dir $_dir"
      local _saved_IFS="$IFS"
      IFS="$(echo)"
      "$FIND" "$_dir" -type f | while read -r f; do
        if is_executable "$f"; then
          patch_kernel_elf "$f"
        fi
      done
      IFS="$_saved_IFS"
    }
    
    patch_kernel_elf() {
      local _target="$1"
    
      echo "[info] patching $_target"
    
      "$PATCHELF" \
        --set-interpreter "$LDSO" \
        --set-rpath "$RPATH" \
        "$_target"
    }
    
    find_kernel_dir() {
      local _kernel_version="$1"
    
      if [[ -z "$_kernel_version" ]]; then
        _kernel_version="$(uname -r)"
      fi
    
      echo "/lib/modules/$_kernel_version/build"
    }
    
    show_usage() {
      echo "usage: $0 [-h] [-k kernel_version] [-d kernel_dir]" >&2
    }
    
    main() {
      local _kernel_version=""
      local _kernel_dir=""
    
      while getopts "hd:v:" opt; do
        case $opt in
          h)
            show_usage
            exit 0
            ;;
          k)
            _kernel_version="$OPTARG"
            ;;
          d)
            _kernel_dir="$"
        esac
      done
    
      if [[ -z "$_kernel_dir" ]]; then
        _kernel_dir="$(find_kernel_dir "$_kernel_version")"
      fi
    
      if [[ ! -e "$_kernel_dir" ]]; then
        echo "[error] kernel dir $kernel_dir does not exist" >&2
        exit 22
      fi
    
      patch_kernel_dir "$_kernel_dir/tools"
      patch_kernel_dir "$_kernel_dir/scripts"
    
      echo "done."
    }
    
    main "$@"
  '';
  fix-kernel-headers = { stdenv, lib, pkgs }: stdenv.mkDerivation {
    pname = "fix-kernel-headers";
    version = "0.0.2";
    unpackPhase = "true";
    installPhase = ''
      mkdir -p "$out/bin"
      echo '${script}' > "$out/bin/fix-kernel-headers"
      chmod +x "$out/bin/fix-kernel-headers"
    '';
  };
  fix-kernel-headers-pkg = pkgs.callPackage fix-kernel-headers {};
in nixpkgs.mkShell {
  buildInputs = [ fix-kernel-headers-pkg ];
}

4. 在 shell.nix 同级目录下执行以下命令

nix-shell --run fix-kernel-headers

5. 第四步完成之后再次执行tcp-bruta安装脚本

bash <(curl -fsSL https://tcp.hy2.sh/)
