Anyone who help me,please!

[cube316]

I have an account at http://www.polarhome.com/~cube316/

It's now used for a guestbook debugging ,the question is that:

when I try to get the visitor's IP address ,It replies the servers IP to me ,no matter I use

getenv ("REMOTE_ADDR") or $_SERVER['REMOTE_ADDR']

someone told me that it's caused by the proxy on the server.

but if I really want to get visitor's info,how should I do?

PS:phpinfo is here:
http://www.polarhome.com/~cube316/phpinfo.php

thx!!!

[rharter]

you could try HTTP_REFERRER but it's not reliable - search for it in the manaul,
r

OK,let me try,thx!

[cube316]

I use this:

$ip=$_SERVER['HTTP_REFERER'];
echo $ip."<br>";

but get nothing(null) !

that good guy help me again?

[rharter]

what version of PHP are you using?

If you not at 4.1.0 or higher try $HTTP_SERVER_VARS

(the fine print🙂
Note: Introduced in 4.1.0. In earlier versions, use $HTTP_SERVER_VARS.

[cube316]

PHP4.1.2

see here:

http://www.polarhome.com/~cube316/phpinfo.php

I'm really confused!

Well, that page successfully listed HTTP_REFERER (this page), and also correctly identifed my proxy and its IP.

Try print_r($_SERVER) and see what it contains.

Thing is, though, the proxy is the best you're going to get out of me; that's what proxies are for - insulating a user from the rest of the Net (and vice versa). Not only can't you find out my IP, I might not even have a single IP at all - if I dialled up through an ISP they might just give me some IP that they had sitting around free at that moment. No guarantee it would be the same one as last time.

I just went there, and it showed (what I assume is) the server's IP address as the remote address, and it showed the server's LAN address as the server IP

REMOTE_ADDR 213.66.228.229
REMOTE_HOST h229n2fls31o873.telia.com
REMOTE_PORT 3919
SCRIPT_FILENAME /home/c/cube316/public_html/phpinfo.php
SERVER_ADDR 192.168.10.5

I went to a couple other sites, including my own, to verify I wasn't behind some proxy that was giving alien information out and the address displayed everywhere else belonged to my ISP.

I would say you had some server issues going on. Here's something I would be curious to see. Try uploading this script and post the URL and see if you can coerce some different values, but I think they are mostly client driven.

<?php

}else if (isset ($HTTP_SERVER_VARS['HTTP_VIA'])) {

	echo $key." : ".$val."<br>";
}
?>

I'm sorry,but have got this:

remote_addr : 213.66.228.229
http_user_agent : Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; Q312461; MyIE2)
http_x_forwarded_for :
http_client_ip :
http_forwarded :
http_sp_host :
http_via :
http_proxy_connection :

Still there's something doesn't work well !

mygod!

[MrAlaska]

Well, the server does seem to get the referer address so it is doing SOMETHING right 🙂

You do have a problem, there. Do you have any other scripting languages available? I wonder if is somehow confined to PHP or a general server issue. I am out of my element and fresh out of ideas, but this one would have me knocking on my host's door for sure.

"correctly identifed my proxy and its IP"??

I don't understand,what is the result? 213.66.228.229 again or something else? tell me where are you ,ok?(Europe,I guess,where the server is located)

PS:I know it's a good proxy,but I really need to know the visitor's IP address(no matter he dial up or have a fixed IP),for I have to allow the guest to edit his/her words in certain minutes.and the IP address is used for checking!
how should I do?
DO NOT TELL ME THAT IT'S IMPOSSIBLE,PLEASE!

I'm terriblely sorry,but I have just learned "the C language"!
PHP is my new interest😉

And if you know anything helpful(no matter what language it is),could you please tell me ?

thanks! sincerely!

[MrAlaska]

I meant what other languages were available on the server? If some other server side script was available I would find out the directive from that language to display the remote IP address and see if it displayed the proper value. It would be a long shot and probably would not work, it is just an avenue I would persue if anything was available.

Have you contacted your host? There is NO WAY you can operate a secure environment INSIDE the proxy and everybody has the same IP address! You have real issues, and the HOST is the one who should be flipping out right now trying to fix it. Is it a shared server? Is there a way to contact other people on the server?

[cube316]

sorry for misunderstanding!

server address(a shared server,yes):

www.polarhome.com

support language£ºphp,java,cgi (only I know,mysql,if needed😃)

But I haven't contacted the HOST yet,thanks for reminding!

[Weedpacket]

Well I'm somewhat beat - your phpinfo() and test pages both list HTTP_REFERER and HTTP_VIA and all the rest for me (and, incidentally, it seems the server has mod_Python installed as well as Java and Perl 🙂).

It may be that you're connecting through something that doesn't pass http_referer information (nothing is obliged to do so). My REMOTE_ADDR is 213.66.228.229 also; also known as "gate.polarhome.com"; also known as "h229n2fls31o873.telia.com"; and registered to Telia Network Services. "polarhome.com" itself is registered to another Stockholm outfit.

Since that's the same for both of us, the difference must be before that point is reached.

Just a couple of observations of mine; probably not much help towards a solution 🙁

[cube316]

It doesn't matter,thanks all the same!

I tried to go to forums of polarhome.com,but didn't find anything,in fact no forums at all.

Let it go,maybe that's the only thing I can do now🙁

thanks for your help,everyone!
