from the README:

|
|
Passive OS fingerprinting is based on information coming from a remote host
|
||
|
|
when it establishes a connection to our system. Captured packets contain
|
||
|
|
enough information to identify the operating system. In contrast to active
|
||
|
|
scanners such as nmap and QueSO, p0f does not send anything to the host being
|
||
|
|
identified.

from the maintainer:
|
||
|
|
|
||
|
|
Use of this program requires read access to the packet filtering
|
||
|
|
device, typically /dev/bpf0. Granting such access allows the users
|
||
|
|
who have it to put your Ethernet device into promiscuous mode and
|
||
|
|
sniff your network. See
|
||
|
|
http://www.infoworld.com/articles/op/xml/00/05/29/000529opswatch.xml
|
||
|
|
if you do not understand how this can be harmful. Running p0f with
|
||
|
|
no options will cause it to analyse packets intended for other
|
||
|
|
hosts.
