Warning found on port netbios-ns (137/udp)

The following 3 NetBIOS names have been gathered :
TEST = This is the computer name registered for workstation services by a WINS client.
WORKGROUP = Workgroup / Domain name
TEST = Computer name that is registered for the messenger service on a computer that is a WINS client.
The remote host has the following MAC address on its adapter :

If you do not want to allow everyone to find the NetBios name
of your computer, you should filter incoming traffic to this port.

[ back to the list of ports ]

Warning found on port general/tcp

The remote host uses non-random IP IDs, that is, it is
possible to predict the next value of the ip_id field of
the ip packets sent by this host.

An attacker may use this feature to determine if the remote
host sent a packet in reply to another request. This may be
used for port scanning and other things.

Solution : Contact your vendor for a patch
Risk factor : Low

[ back to the list of ports ]

Warning found on port general/icmp

The remote host answers to an ICMP timestamp
request. This allows an attacker to know the
date which is set on your machine.

This may help him to defeat all your
time based authentifications protocols.

Solution : filter out the icmp timestamp
requests (13), and the outgoing icmp
timestamp replies (14).

Risk factor : Low
CVE : CAN-1999-0524
