Show # Of Users Connected To FTP Server

_PQ3_RogeR

I want to show the number of users connected to my anonymous ftp site which people download from on a page so they know when it's full. I'm using RedHat 7.2 with ProFTPD.

What would the code look like?

Thanks,

I did this once.

I did:

exec("ps -elf | egrep ftpd",$tet);

for($l=0;$l<count($tet);$l++){
if(!eregi("egrep",$tet[$l]) && !eregi("accepting connections",$tet[$l])){
$user[]=$tet[$l];
$c++;
}
}

echo "There are $c ftp users.";

And an array $user would have all users names signed in.

I used this with slackware and redhat, using proftpd.

It's just saying "There are ftp users." The # isn't showing up.

PyroX

<?
$c=0;
exec("ps -elf | egrep ftpd",$tet);
for($l=0;$l<count($tet);$l++){
if(!eregi("egrep",$tet[$l]) && !eregi("accepting connections",$tet[$l])){
$user[]=$tet[$l];
$c++;
}
}
echo "There are $c ftp users.";
?>

It says "There are 0 ftp users." now. There really are like 40.

PyroX

modify like this:

exec("ps -elf | grep ftpd",$tet) or die("failed");

Last note,
I dont remember, I may have chmod 755 /usr/bin/ps and /usr/bin/egrep

_PQ3_RogeR

failed.. I chmoded those files also.

_PQ3_RogeR

any idea?

_PQ3_RogeR

ok, it works now. PHP safe mode was compiled on.

The last problem in the php code is I want it to show the # of FTP spots actually taken, like the # it shows when you use the "ftpwho" command. It's showing a number higher than the max users since the max instances is 48.

PyroX

then just change that command to ftpwho
exec("ftpwho",$tet);

And modify the code.

_PQ3_RogeR

I'm not sure how the code would look when using the ftpwho command. Just chaning the command doesn't work.

PyroX

Try this:

<?
$c=0;
exec("ftpwho",$tet);
for($l=0;$l<count($tet);$l++){
echo $tet[$l]."<BR>";
$c++;
}
}
echo "There are $c ftp users.";
?>

To at least see if it works, you may need to give permissions for ftpwho like you may of needed to do for the others.

Parse error: parse error, unexpected '}' in /home/virtual/site1/fst/var/www/html/ftpwho.php on line 8

I got rid of the } and the code ran but it showed "0" users. I chmoded /usr/bin/ftpwho also.
