There is a utility called pmwho:
http://www.vii.com/portmaster/pmwho.html
that operates more-or-less like a finger command, and you could easily
pipe that to an HTML interface. The problem with that, though, is
that it telnet's into the portmaster, and must therefore be compiled
(or called) with the portmaster's password. If you're careful, and on
a trusted machine, this wouldn't be too bad.
A better solution is to use SMNP as you can do this with the read
community string, which is safer than putting your PM's passwords in a
file somewhere. The following snippet of Perl does just this, using
snmpwalk (note that this is an old version -- newer versions of
snmpwalk may require SNMP version information on invocation.
-------------
$script = "pmfinger";
use Getopt::Std;
$public="Your public string";
getopt('p');
if ($opt_p eq "")
{
die "usage: $script -p portmaster\n";
}
$date = `date`;
chop($date);
@users = `snmpwalk $opt_p $public .1.3.6.1.4.1.307.3.2.1.1.1.4 | grep \
-E \"\\\".+\\\"\" | cut -d\"\\\"\" -f 2 `;
print "Current login utilization for $opt_p:\n";
foreach $user (@users)
{
chop ($user);
print "User: $user\n";
}
------------
A more elegant solution would to be to use the SNMP perl module, and
do something like:
use SNMP 1.7;
$session = new SNMP::Session ( DestHost => $host,
Community => "$community");
$host = $session->{DestAddr};
########################
# We assume 48 ports :-)
########################
for ($i=1; $i<48;$i++)
{
$port = $session->get("enterprises.307.3.2.1.1.1.2.$i");
$type = $session->get("enterprises.307.3.2.1.1.1.3.$i");
$user = $session->get("enterprises.307.3.2.1.1.1.4.$i");
$time = $session->get("enterprises.307.3.2.1.1.1.9.$i")/100;
# ...and do stuff here.....
}
Safer: no password compromise...
