[mrtg] improved dhcp script

[Eric Garnel]

I improved the dhcp script I wrote a while back for MRTG. It is now
only a single perl script and runs faster. Still requires fping.

$alive = `/usr/sbin/fping -ga 127.14.29.30 127.14.29.250 | wc -l`;
$alive =~ s/ +//;

chop($alive);

$alive--;

print("$alive\n");
#
# now show who is not up
#
$dead = `/usr/sbin/fping -gu 127.14.29.30 127.14.29.250 | wc -l`;
$dead =~ s/ +//;

chop($dead);

$dead--;

print("$dead\n");
print "0\n";
print "0\n";
