Hi,

Just curious as to what systems or for what reasons one would have a TCP 
Maximum Segment Size equal to 1372. I've never used an OS configured 
this way by default.

IP Address: 	124.0.225.70
  Distance: 		20
  Type: 		REMOTE host
Fingerprint: 	16A0:055C:40:00:1:1:1:1:A:3C
  Operating System: 	unknown fingerprint (please submit it)
  Nearest one is: 	Linux 2.4.xx
Port: 	TCP 80 | http

IP Address: 	199.166.6.100
  Hostname: 	execulink.com
  Distance: 		6
  Type: 		REMOTE host
Fingerprint: 	16A0:055C:40:00:1:1:1:1:A:3C
  Operating System: 	unknown fingerprint (please submit it)
  Nearest one is: 	Linux 2.4.xx
Port: 	TCP 25 | smtp
Port: 	TCP 110 | pop-3

IP Address: 	61.129.102.116
  Distance: 		17
  Type: 		REMOTE host
Fingerprint: 	4050:055C:80:00:1:1:1:1:A:40
  Operating System: 	unknown fingerprint (please submit it)
  Nearest one is: 	OpenBSD 3.2
Port: 	TCP 80 | http

I've learned that the above results are often times unreliable since 
ettercap falsely fingers some of my own hosts as Windows.

IP Address: 	192.168.144.122
  MAC address:
  Manufacturer: 	D-Link
  Distance: 		0
  Type: 		LAN host
Fingerprint: 	16D0:05B4:40:02:1:1:1:1:S:3C
  Operating System: 	unknown fingerprint (please submit it)
  Nearest one is: 	Windows
Port: 	UDP 68 | dhcpclient
Port: 	UDP 123 | ntp

Thanks,
Greg
