IP Detection

***Sick Dwarf*** · April 21st, 2002, 06:41 AM

Does anyone know a good javascript for IE and Netscape that detects and displays the user's IP Address. I've been looking all over, but none off them seem to work.

Thanx

Well, I tried this one out, it works in Opera for me. Haven't tested in IE or Netscape though, hopefully it'll work in there. Just make sure Java is enabled, otherwise, it doesn't work. It gives the computer name and IP address.

<html>
<head>
<title>Displaying the user's IP Address</title>
</head>
<body>
<script type="text/javascript">
var address = java.net.InetAddress.getLocalHost();
document.write("Your IP is: " + address);
</script>
</body>
</html>

Basically, all you need to know is that java.net.InetAddress.getLocalHost() gives you the info you want.

Well, everytime I use that line I get a message saying: "Java is not defined".
I'm beginning to think that it's not the script that's wrong, but my computer. Can I get a Javascript update somewhere?

I would suggest not to take the JavaScript way. Javascript is very limited in most things it does, and it easily can be by-passed (uh...you know it). Try making/getting a server-side script (in Perl/PHP,etc.etc.) that gets the IP and displays it. This is the safest bet to get accurate IP detection.

my files are all fugged up here...

<SCRIPT>
var ip = new java.net.InetAddress.getLocalHost();
var ipStr = new java.lang.String(ip);
document.writeln(ipStr.substring(ipStr.indexOf("/")+1));
</SCRIPT>

is a netscape one i think

this other uses the ol .shtml extension

http://wsabstract.com/script/script2/displayip.shtml

i used that on my ol server but this other one i have now doesnt allow that...not sure if thats the norm or not...

p.s its hard to find one that works for IE i recall

possibly use a stats counter ? it wont display it unless they click it but they'l know its a counter....hmmm

If you were using PHP, I believe this would work

PHP Code:


<?php

echo $REMOTE_ADDR;

?>

You could also use this handy-dandy perl script to check the ip address.

#!/usr/bin/perl
print $ENV{'REMOTE_ADDR'};

This is a log script that I wrote to log users on my web server.It gets the local time as well.I like this because it writes it to a file as well.Feel free to modify it...its all open sorce and all that.

Code:

Perl
#!/usr/bin/perl
#!c:/apache/perl/nsperl.exe
print "Content-type: text/html\n\n";

#change this to the file you have your logs at eg. /log/log.txt or c:\log\log.txt
$logfile = 'c:\log\log.txt';
#gets the users IP address
$ip = $ENV{'REMOTE_ADDR'};
#get the time from the server
($sec,$min,$hour,$mday,$mon,$year,$wday,$ydat,$isdst) = localtime();

#calls the print_html sub
print_html();

#opens the file and formats the data
open(LOGFILE, ">>$logfile") or die ("can't open file.\n");
print LOGFILE ("Ip=$ip Date=$mon/$mday Time=$hour:$min:$sec\n");
close(LOGFILE);

#-------------------user defined sub(s)-------------------#
sub print_html {
	print "<htmL><head><title>Log screen</title></head>\n";
	print "<body>\n";
	print "Hello ,$ip. 
you have come to this part of the web
\n";
	print "at $hour:$min:$sec on $mon/$mday.
\n";
	print "</body></html>\n";
	}

Sorry I forgot to say This script is in perl so you need a working CGI-BIN and the right permissions I think 0755 will do just fine.
