Nmap 2.54BETA2 released

I am pleased to announce the release of Nmap 2.54BETA2. Here are some of
the most important changes:
-- Added a shortcut which can make single port SYN scans of a network
much faster. For example, if a new sendmail vulnerability is
found, this reduces the time it takes to scan your whole network
for port 25. This shortcut takes effect when you do "-PS<port> -sS
-p<port>". For example 'nmap -n -sS -p25 -PS25 126.96.36.199/8". This
optimization doubled the scan speed in a 30,000 IP test I performed.
-- Added -sL (List scan). Just as ping scan (-sP) allows you to short
circuit the scan right after pinging, -sL allows you to short
circuit the scan right after target selection. This allows you to
see what hosts WOULD be scanned without actually doing it. The
hosts will be resolved unles you use -n. Primary uses:
1) Get all the IPs in a network (like A.B.C.D/16) and take out
machines that are too fragile to be scanned safely before
calling Nmap with the new list (using -iL).
2) Test that a complex spec like 128.4,5,7-9.*.7 does what you
expect before actual scanning.
3) When all you want to do is resolve a bunch of IPs.
4) You just want results of a zone transfer (if/wnen implemented).
-- Added some new fingerprints and adjusted some others based on
submissions to the DB (I still have a lot more to go through so
don't worry if your submission is still not detected).
-- Added a warning when you scan 0 hosts (eg "nmap -v"). There are
various other output tweaks as well.
For those of you running Linux/x86 w/a recent version of rpm
(www.rpm.org), you can install/upgrade to the newest version of
nmap/nmapfe with these commands:
rpm -vhU (nmap url)
where (nmap url) is one (or both) of these:
source tarballs and source RPMs are available at:
Let me know if you find any problems.
