Software Release - fwsnort-1.0.5
21 August, 2008
The 1.0.5 release of fwsnort is available for
download. For this release
all Snort rules and perl modules packaged within the fwsnort sources have been
moved into the deps/ directory so that it is clear which components are dependencies,
and this change makes it easy to build "nodeps" tar archives and RPMs of fwsnort
that do not include any dependencies. This change was suggested by
Franck Joncourt in support of his efforts to
create Debian packages of fwsnort, and this will also mean that fwsnort will integrate
easily into Linux distributions such as Ubuntu). Also, from now on, all cipherdyne.org
project will be signed with a new GnuPG key that is dedicated just for this purpose,
and this key can be downloaded here.
The complete ChangeLog for fwsnort-1.0.5 appears below:
- Replaced the bleeding-all.rules file with the emerging-all.rules file. This is because Matt Jonkman now releases his rule sets at http://www.emergingthreats.net/
- Restructured perl module paths to make it easy to introduce a "nodeps" distribution of fwsnort that does not contain any perl modules. This allows better integration with systems that already have all necessary modules installed (including the IPTables::ChainMgr and IPTables::Parse modules). The main driver for this work is to make all cipherdyne.org projects easily integrated with distributions based on Debian, and Franck Joncourt has been instrumental in making this process a reality. All perl modules are now placed within the "deps" directory, and the install.pl script checks to see if this directory exists - a separate fwsnort-nodeps-<ver> tarball will be distributed without this directory. The Debian package for fwsnort can then reference the -nodeps tarball, and a new "fwsnort-nodeps.spec" file has been added to build an RPM from the fwsnort sources that does not install any perl modules.
- Updated to import perl modules from /usr/lib/fwsnort, but only if this path actually exists in the filesystem. This is similar to the strategy implemented by psad. A new variable FWSNORT_LIBS_DIR was added to the fwsnort.conf to support this.
- Added support for multiple Snort rule directories as a comma-separated list for the argument to --snort-rdir.
- Moved 'threshold' to the unsupported list since there will be several signatures that use this feature to detect the Dan Kaminsky DNS attack, and fwsnort does not yet support the usage of the iptables --limit match.
