Hi, I wrote the Bacula LStat decoder implementation in PHP. I made WebGUI for this also. Now online LStat decoder (beta version) is available on my page Bacula.pl:
http://www.bacula.pl/bacula-lstat-decoder/ In the near future I need to make description of fields. Here is Bacula LStat decoder function in PHP: function decode_bacula_lstat($lstat) { $base64 = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/'; $lstat = trim($lstat); $lstat_fields = explode(' ', $lstat); if(count($lstat_fields) !== 16) { die('Error! Number of lstat fields is invalid. Please make sure that it is valid lstat string.'); } list($dev, $inode, $mode, $links, $uid, $gid, $rdev, $size, $blksize, $blocks, $atime, $mtime, $ctime, $linkfi, $flags, $data) = $lstat_fields; $encoded_values = array('dev' => $dev, 'inode' => $inode, 'mode' => $mode, 'links' => $links, 'uid' => $uid, 'gid' => $gid, 'rdev' => $rdev, 'size' => $size, 'blksize' => $blksize, 'blocks' => $blocks, 'atime' => $atime, 'mtime' => $mtime, 'ctime' => $ctime, 'linkfi' => $linkfi, 'flags' => $flags, 'data' => $data); $ret = array(); foreach($encoded_values as $key => $val) { $result = 0; $is_minus = false; $start = 0; if(substr($val, 0, 1) === '-') { $is_minus = true; $start++; } for($i = $start; $i < strlen($val); $i++) { $result <<= 6; $result += strpos($base64, substr($val, $i , 1)); } $ret[$key] = ($is_minus === true) ? -$result : $result; } return $ret; } and here is usage for this: $lstat = 'gB DL+b IGg B A y A D5dZR BAA fN4 BNeR+z BNeR+7 BNeR+7 A A C'; $decoded_lstat = decode_bacula_lstat($lstat); print_r($decoded_lstat); Any suggestions and modifications are welcome.
