Ideas of making u-232 ipv6 able.

[baiyou2015]

Good idea, look forward to adding ipv6 support

[antimidas]

nice! good topic.... Will have to be addressed sooner or later

This topic is about the start of making u-232 versions ipv6 able.
This is very unfinished and basically a topic about getting ideas how to do it.
Original idea started out from http://php.net/manual/en/function.ip2long.php
you will need php gmp-lib cause ipv6 is so long and also to alter in phpmyadmin all ip fields like the one in uses to 59 length or more

Code Select Expand

ALTER TABLE `failedlogins` CHANGE `ip` `ip` VARCHAR(59) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL;
ALTER TABLE `users` CHANGE `ip` `ip` VARCHAR(59) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL;

1st off you will need these functions in bitorrent.php
this is taken from https://github.com/Arkhana/TorrentTrader2.08/blob/master/upload/backend/functions.php

function is_ipv6 ($s) {
return is_int(strpos($s, ":"));
}
// Taken from php.net comments
function ip2long6($ipv6) {
  $ip_n = inet_pton($ipv6);
  $bits = 15; // 16 x 8 bit = 128bit
  while ($bits >= 0) {
    $bin = sprintf("%08b",(ord($ip_n[$bits])));
    $ipv6long = $bin.$ipv6long;
    $bits--;
  }
  return gmp_strval(gmp_init($ipv6long,2),10);
}
function long2ip6($ipv6long) {
  $bin = gmp_strval(gmp_init($ipv6long,10),2);
  if (strlen($bin) < 128) {
    $pad = 128 - strlen($bin);
    for ($i = 1; $i <= $pad; $i++) {
    $bin = "0".$bin;
    }
  }
  $bits = 0;
  while ($bits <= 7) {
    $bin_part = substr($bin,($bits*16),16);
    $ipv6 .= dechex(bindec($bin_part)).":";
    $bits++;
  }
  // compress
  return inet_ntop(inet_pton(substr($ipv6,0,-1)));
}

replace in same file

That should be basic ban checks it might give you ideas how to change the rest of them.
Feel free to post if you got other ideas.
