REMOTE_ADDR displays only 0.0.0.0 -- mod_proxy special config on Windows

[SteveKim]

I've turned off showing IP address at the footer for some time and had it turned on couple days ago to find out it only displays 0.0.0.0. So I've turned it off until problem gets resolved.

I also get 0.0.0.0 on who's online under Admin/Tools.

What would cause $ip = $_SERVER['REMOTE_ADDR'] to get only 0.0.0.0?

If you must ask what contributions I've installed, there are about 50 of them (pretty much everything from the download section). They all work fine and most of them use overrides and I don't remember touching display ip section. (I can almost guarantee particular code hasn't been touched).

Again, what would have caused $ip = $_SERVER['REMOTE_ADDR'] not to obtatin proper client IP??

I just realized it is to do with mod_proxy of Apache.
Any workarounds in using mod_proxy with Remote_addr?

Try using zen_get_ip_address() instead of $_SERVER['REMOTE_ADDR']

Dr Byte,

I've added couple things under tpl_footer.php just to see what values these variables return as zen_get_ip_address() also returned only 0.0.0.0 as below:

<div id="siteinfoIP"><?php echo TEXT_YOUR_IP_ADDRESS . '  ' . 'server forwarded: ' .  
$_SERVER['HTTP_X_FORWARDED_FOR'] . ' server client ip: '. $_SERVER['HTTP_CLIENT_IP'] . 'get 
forwarded: ' . getenv('HTTP_X_FORWARDED_FOR') . 'get client ip: ' . getenv('HTTP_CLIENT_IP') . 
'get remote addr: ' . getenv('REMOTE_ADDR') . 'zen ip func: ' . zen_get_ip_address(); ?></div>

and it returns below:

Your IP Address is: server forwarded: server client ip: get forwarded: get client ip: get remote addr: 0.0.0.0zen ip func: 0.0.0.0

Any other suggestions?

Other than turning it off? No.
If the proxy isn't passing the information through, then there's no way of knowing.
Why do you need the mod_proxy installed anyway?

Well, I'm sure you'd understand that all business necessities are different.

Mine here has couple of almost inavtive 'old' asp sites (not aspx) that is maintained by some other person whose main job is not to maintain asp sites and those sites are not justifiable in spending extra dollar to convert to anything else like php.

In other words, asp sites require IIS, IIS and Apache cannot be hosted at the same server, .aspx mod in Apache is available but not .asp hence Apache is proxying IIS sites. So we need it.

Then here is another question that's not quite appropriate in this Zen Cart forum. Will X-Forwarded-For require another Apache module installed? Could this requirement being not in place probably cause X-Forwarded-For variable not available?

Thanks,

Steve Kim.

I have the same problem. Tried this and no go.
WinXP wamp 5, don't know anything about mod_proxy, looked at the Apache server settings and proxy_module nor any of the other proxy options are turned on.

Exactly. Hence the question.

I'm not sure -- I've not used the mod_proxy addon in order to know.

FWIW, Zen Cart checks all those variations in its get_ip_address function

  function zen_get_ip_address() {
    if (isset($_SERVER)) {
      if (isset($_SERVER['HTTP_X_FORWARDED_FOR'])) {
        $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
      } elseif (isset($_SERVER['HTTP_CLIENT_IP'])) {
        $ip = $_SERVER['HTTP_CLIENT_IP'];
      } else {
        $ip = $_SERVER['REMOTE_ADDR'];
      }
    } else {
      if (getenv('HTTP_X_FORWARDED_FOR')) {
        $ip = getenv('HTTP_X_FORWARDED_FOR');
      } elseif (getenv('HTTP_CLIENT_IP')) {
        $ip = getenv('HTTP_CLIENT_IP');
      } else {
        $ip = getenv('REMOTE_ADDR');
      }
    }

    return $ip;
  }

You may have to take your question to a webhosting discussion forum like webhostingtalk.com where you can "talk shop" with folks running servers more actively.

Thank you, Dr. Byte. We all must do.

I'll post once it's resolved.

Just another note: the zen cart sites are not proxied and this is happening. The environment is mod_proxy loaded here.

[SteveKim]

I've got it resolved by searching through apache lounge at http://www.apachelounge.com/forum/viewtopic.php?p=7476

It probably applies only to my environment that is Win2K server with mod_proxy (proxy_html) though.

The resolution:

Simply add following to anywhere in httpd.conf, of which in my case, at the end of the file:

Win32DisableAcceptEx

More about it on http://httpd.apache.org/docs/2.0/mod/mpm_winnt.html
Hope this helps others whom having the problem!
