# URL you can use to submit the fingerprint.  If Nmap guesses wrong,
# please send the full Nmap output and the exact destination host OS
# name and version to fyodor@insecure.org .  Thanks!

# TEST DESCRIPTION:
# Tseq is the TCP sequenceability test
# T1 is a SYN packet with a bunch of TCP options to open port
# T2 is a NULL packet w/options to open port
# T3 is a SYN|FIN|URG|PSH packet w/options to open port
# T4 is an ACK to open port w/options
# T5 is a SYN to closed port w/options
# T6 is an ACK to closed port w/options
# T7 is a FIN|PSH|URG to a closed port w/options
# PU is a UDP packet to a closed port

# Notes on NetBSD (written by Charles M. Hannum <root@ihack.net>):
# * The set of options in a SYN-ACK depends on the state of the
#   `net.inet.tcp.rfc1323' flag.
# * Releases prior to 1.3 did not randomize the ISS at all.
# * Releases prior to 1.3 incorrectly added the IP header length to the IP
#   packet length when returning an ICMP unreachable.
# * Releases prior to 1.3 calculated the window size slightly wrong.
# * Releases prior to 1.3 returned a non-zero window size when sending a RST
#   in response to an ACK on a listening socket (thereby making them
#   susceptible to stealth scanning).
# * Releases prior to 1.3H/1.3.4 did not return a response to the null flag
#   test (thereby making them susceptible to stealth scanning).
# * Releases prior to 1.3I/1.3.4 corrupted some of the IP header fields in
#   the encapsulated IP header when sending an ICMP reply.  On little endian
#   machines the IP ID field was byte-swapped.  The checksums were always
#   zeroed.
# * Releases prior to 1.3I/1.3.4 did not set the DF bit in a SYN-ACK when
#   MTU discovery was enabled.
