Hello everyone,

I am pleased to announce that Nmap 2.30BETA17 has been released.  This
version offers a number of cool new features and changes from Beta14.
Here is the list (download URLs are below it):

-- Added ACK scanning.  This scan technique (which van Houser and
   others have been bugging me to add for years :), is great for
   testing firewall rulesets.  It can NOT find open ports, but it can
   distinguish between filtered/unfilterd by sending an ACK packet to
   each port and waiting for a RST to come back.  Filtered ports will
   not send back a RST (or will send ICMP unreachables).  This scan
   type is activated with -sA .

-- Documented the Window scan (-sW) which Lamont Granquist added in
   September 99.

-- Added a whole bunch of OS fingerprints that people have submitted.

-- "Protocol" field in output eliminated.  It is now printed right
   next to the number (/etc/services style).  Like "22/tcp".  I wonder
   what I should put in the extra white space this leaves on the
   report :).

-- Added --resume option to continue a large network scan where you
   left off.  This is useful for recovering from errors (modem drops
   carrier, network outage, etc).  It also allows you to start and
   stop for policy reasons (like if a client only wants you to scan on
   weekends or at night) or if you want to run the scan on a different
   host.  Usage is 'nmap --resume logfile' where logfile can be either
   normal (-oN) or machine parseable (-oM) logfile from the scan that
   was aborted.  No other options can be given (the options in the
   logfile from the original scan will be used).  Nmap will start off
   with the host after the last one successfully scanned in the log

-- Added --append_output option which causes -oN/-oM/-oS to APPEND to
   the output file you specify rather than overwriting it.

-- Various internal code cleanup, makefile fixes, etc.

-- Changed version number from 2.3BETA* to 2.30BETA* to appease
   various packaging systems that thought 2.3BETA was < 2.12 .

-- Nmap output to files now correctly flushes output after scanning
   for each host is finished.

-- Fixed compiler -L flags error found by Ralf Hildebrandt
   <R.Hildebrandt () tu-bs de>

-- Fixed configure scripts so that options you give to the Nmap
   configure (like --prefix ) are also passed to the nmapfe configure
   script.  This problem was noted by Ralf Hildebrandt
   <R.Hildebrandt () tu-bs de>.  While I was at it, I added some other
   cleanups to the system.

-- Added --noninteractive option for when nmap is called from scripts
   (where stuff like prompting users for info is unacceptable).  It
   does not currently do anything (Nmap never prompts) and script
   writers should probably wait until at least May '2000 so their
   scripts still work with earlier versions of Nmap.

-- Updated to the latest config.guess and config.sub from Autoconf 2.13

-- Applied patch by Sven <s.carstens () gmx de> which fixes a segmentation
   fault problem in Nmapfe colored mode as well as some output niceties.

-- Changed some C++ comments to C-style for portability (noticed by 
   "Sergei V. Rousakov" <sergei () cas Vanderbilt Edu> )

For those of you running Linux/x86 w/rpm (www.rpm.org), you can
install/upgrade to the newest version of nmap/nmapfe with these

rpm -vhU ftp://ftp.server51.freshmeat.net/pub/nmap/nmap-2.30BETA17-1.i386.rpm
rpm -vhU ftp://ftp.server51.freshmeat.net/pub/nmap/nmap-frontend-2.30BETA17-1.i386.rpm

source tarballs and source RPMs are available at:
http://www.insecure.org/nmap or ftp://ftp.server51.freshmeat.net/pub/nmap

Please try these out and let me know if you have any problems.  A NON-BETA
release is coming very soon, so now is the time to mention any problems
which you do not want to be in the stable release.
