The other night I did a nessus security scan on my freeBSD box and I got the
following warning. I am hopping someone on this mailing list can give me a
better idea what this warning means.
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 portscanning and other things.
Solution : Contact your vendor for a patch
Risk factor : Low
