Getting user name?? (Windows user)

[astur]

Is there any way to get the user's name?

I know that time ago, I visited a page that displayed ALL the info about me, what IE version, and even my user name (Administrator) and if I had a password or not (obviously not the password if I had one).

Is there any way to get it in php?

Since it's not possible to get the MAC addy, IPs do change, most users connect thru a proxy and most people "clean" their cookies every few days... I want to get all the information possible from the user so I can know when the user is back, or at least approximately by taking a look at my database.

Besides that, using cookies, is there any way to store in a cookie a UNIQUE value that I can read when the user is back??? I .E. a combination of timestamp and that -possible to get- windows user name, or timestamp and IP. (its very unlikely to have someone reading the same page, when setting the cookie, at the same time so they have the same timestamp and they have also the same proxy IP). Anyway I think that even with the timestamp it would be enough, i think its accurate enough and almost impossible to have two users at the same time getting the cookie set.

WEll sorry, for this newbie fuss.

I don't know if this is the way you want to go, but I would create a login where the user has to log in to see your content, & then add a timestamp feild to the users database, or even a seperate table that records all login timestamps.

i BELIEVE its under $_ENV but i could be wrong.

Try $_ENV['USERNAME']

just tested doesnt work on WinXP. i know there is a way though.......

I tried the $_ENV['USERNAME'] on Win2k and it doesn't work, anyway I will do what cascade said, it seems the easies thing, I will force the user to log in.

thank you for your answers!

Is there any way to get the user's name?

I use nbtscan to gather user info on our intranet... might not be too usefull over the Internet though.

example on linux server:

exec("/var/www/cgi-bin/nbtscan $REMOTE_ADDR", $RawUserData);
$UserData = ereg_replace (' +', ' ', $RawUserData[0]);

$dparts = explode(" ", $UserData);
$uparts = explode("=", $UserData);
$DomainPC = explode("\\", $dparts[1]);

$UserDomain = trim($DomainPC[0]);
$UserPC = trim($DomainPC[1]);
$UserName = trim($uparts[1]);

echo "IP: <strong>$REMOTE_ADDR</strong>";
echo "<p> Domain: <strong>$UserDomain</strong>"; 
echo "<p> PC: <strong>$UserPC</strong>";
echo "<p> User: <strong>$UserName</strong>";

Nice BigZack 🙂

Had to do a little re-arranging to get it going on a Windoze machine, so here's the code for that...

<?
exec("C:\\nbtscan ".$_SERVER['REMOTE_ADDR'], $UserData); 
$new = array();
$split = explode(" ",$UserData[4]);
for($i=0;$i<count($split);$i++) {
	if($split[$i] != "" && ($split[$i] != "<server>")) {
		array_push($new, $split[$i]);
	}
}

echo 	"IP Address: ".$new[0]
	."<br>Computer Name: ".$new[1]
	."<br>User: ".$new[2]
	."<br>MAC Addy: ".$new[3];
?>

see if this works, though i only got it to work locally, or thru a intranet

<?php $username = str_replace("DOMAIN\\\\", "", $_SERVER['REMOTE_USER']); ?>
Hello <?php printf("$username"); ?>, and welcome!
