[ipxe-devel] Unable to load custom menu in gPXE / iPXE scripts chaining to pxelinux.0 with dhcp option 209

[Slawomir Latkowski]

Hi,

The way i use it is the latest syslinux 4.04 menu.c32 and use menu.c32
directly as follows boot.php:


<?php

header ( "Content-type: text/plain" );

$uri=$_SERVER["REQUEST_URI"];
$dir=substr ( $uri, 0, strrpos ($uri, "/") + 1);

echo "#!gpxe\n";
echo "imgfree\n";
echo "login\n";
echo "chain ".
     "https://\${username:uristring}:\${password:uristring}@".
     $_SERVER["HTTP_HOST"].$dir.
     "menu.c32 menu.php\n";
?>


menu.php needs small correction:


  <?php

  header ( "Content-type: text/plain" );

  $username = $_SERVER["PHP_AUTH_USER"];
  $password = $_SERVER["PHP_AUTH_PW"];

  $index = 0;

  function title ( $title ) {
    global $username;
    echo "menu title ".$title;
    echo ( $username ? " for ".$username : "" )."\n";
  }

  function label ( $label ) {
    global $index;
    $index++;
    echo "label item".$index."\n";
    echo "  menu label ";
    echo "^".( ( $index < 10 ) ? $index :
               sprintf ( "%c", $index + ord ( 'A' ) - 10 ) )." ";
    echo $label."\n";
  }

  function sanboot ( $label, $root_path ) {
    label ( $label );
    echo "  kernel cmd.c32\n";
    echo "  append sanboot ".$root_path."\n";
    echo "\n";
  }

  function uriboot ( $label, $uri, $args ) {
    label ( $label );
    echo "  kernel ".$uri."\n";
    if ( $args )
        echo "  append ".$args."\n";
  }

  function retry () {
    echo "label failed\n";
    echo "  menu label Authentication Failed\n";
    echo "  menu disable\n";
    uriboot ( "Try again", "boot.php", "" );
  }

  function authenticated () {
    global $username;
    global $password;

    switch ( "$username:$password" ) {
    case "mcb30:password":
    case "guest:guest":
      return 1;
    default:
      return 0;
    }
  }

  ?>

  menu background atlantis.png
  prompt 0
  timeout 100
  allowoptions 0
  menu timeoutrow 29
  menu vshift 2
  menu rows 8
  menu color title  1;36;44   #ff8bc2ff #00000000 std
  menu color unsel  37;44     #ff1069c5 #00000000 std
  menu color sel    7;37;40   #ff000000 #ffff7518 all
  menu color hotkey 1;37;44   #ffffffff #00000000 std
  menu color hotsel 1;7;37;40 #ff000431 #ffff7518 all

  <?php // <<<<<<<<<<<<<<<<<<<<<<< THIS PART IS MISSING

  title ( "Secure Network Boot" );

  if ( ! authenticated() ) {
    retry();
  } else {

    if ( $username == "mcb30" ) {

      sanboot ( "MS-DOS 6.22",
                "iscsi:chipmunk.tuntap::::iqn.2007-07.chipmunk:msdos622" );

      sanboot ( "Windows 2k3",
                "iscsi:chipmunk.tuntap::::iqn.2007-07.chipmunk:win2k3" );

    }

    uriboot ( "Linux rescue shell",
              "http://chipmunk.tuntap/images/uniboot/uniboot.php", "" );
  }

  ?>

It works with me
Hope it helps.

Slawek
