Posadis 0.60.5 released!

Posadis 0.60.5 was released mainly to provide a solution (at least I hope so) to the 100% CPU usage problem reported with earlier 0.60.* versions.

Apart from that, this release incorporates the initial cache file support from update 1 to Posadis 0.60.4 as well; other than that, nothing much has changed. An upgrade is recommended to anyone running Posadis as a DNS cache. To fix the problem, just upgrading the Posadis package and leaving Poslib and Mfedit as-is is enough. ... read more

much enhanced documentation, DNS notify support and support for using

Updated RPM package for Posadis monitor

Thursday, 04 December 2003

Today, a new RPM package for the Posadis-monitor module for Posadis 0.60.2 was created to overcome problems with monitored master files that would not be updated due to Monitor still sending out the old 'update_ttl' command which is no longer supported in 0.60.2. This was fixed before 0.60.2, but the RPM of Monitor was apparently built before this.

The source code and Windows releases of the Monitor module do not have this problem.... read more

Posadis 0.60.1 is out!

Well, Posadis 0.60.0 was a fun ride while it lasted, but based on the feedback I received after the release, I was forced to release new versions of the Posadis programs to conquer problems that arose.

That's why I proudly release Posadis 0.60.1, which is mainly a bugfix release over 0.60.0, though it contains some new features as well. Since this release doesn't address any security problems, there's no really urgent need to upgrade if it all works for you, though this new release does fix a few important bugs. An upgrade of Poslib is highly recommented since it fixes a major bug in the TCP code.... read more

Posadis 0.60.0 is out

Finally, after nine months of hard work, Posadis 0.60.0 is ready! Posadis 0.60.0, which is a complete re-write of Posadis, now supports caching and resolving, it has a plug-in system, and it can monitor your files for activity. Also, I hope the 100% CPU usage problems of Posadis 0.50.x now finally belong to the past.

Also, the website has been completely revamped, so go to


quickly and get your Posadis 0.60.x build while it's hot!

Security vulnerability in Posadis 0.50.x

A security vulnerability has been found in Posadis releases 0.50.4 through 0.50.8, causing malicious users to crash the DNS server by sending a specific faulty DNS message. An upgrade is recommended for all users asap.

First public release of SANS

Sans is a simple new authoritive Domain Name Server based on poslib [http://www.posadis.org/poslib/], which runs on Windows systems. It features a nice zone editor, in which you can edit changes in real time, and it can import and export BIND-compatible master files. It currently only acts as a primary master: it can't be a secondary for your domains.

More information is available at http://www.posadis.org/sans/.

Posadis 0.50.7 additional DLLs

The original Win32 release of Posadis missed a few DLL files, causing the configuration center not to work on older Windows versions (Windows 95 is known to have this problem; XP works fine). This file had the filename posadis-0.50.7.exe. A new file, posadis-0.50.7-1.exe has been posted to fix this problem.

Root nameservers change!

Today, Verisign anounced they will change the IP address of the

documentation, you should change

Posadis m5pre2a update for win32

The bug fix release m5pre2 for win32 contained a bug causing log messages not
to be displayed in the log window. This bug has been fixed in this new

An upgrade is recommended for anyone who is currently using m5pre2, and
probably also earlier versions, since m5pre2 fixes the (perhaps remotely
exploitable) logging bug.

Posadis m5pre2 released!

As reported on Bugtraq March 27 2002, the logging mechanism of Posadis contains a serious bug. According to the author, "there are a few possible methods of remote exploitation". Posadis m5pre1 and earlier can easily be segfaulted by embedding C formatting characters into configuration files or on the command line, but segfaulting Posadis with a remote query seems a bit more troublesome.... read more

Posadis m5pre1 released!

Today, the Posadis Team proudly announces the release of Posadis m5pre1,
the latest stable version of our DNS server.

Posadis m5pre1 is the first release in the 0.50.x series, which contains
a major rewrite of much important code. We believe Posadis m5pre1 is
more stable and secure than the 0.40.x series.

Here's the contents of the NEWS file:

o (Win32 only) Graphical logging window
o (Unix only) Option to run in the background
o Various stability and security fixes
o Official 64-bits support!... read more

Posadis Win32 installer fixed

It appears the installer for Posadis 0.40.2, as posted to the Sourceforge file list on 7 february, contained a serious error: the data directory wasn't stored in the Win32 registry, thus potentially causing Posadis to panic on startup.

The 0.40.2 installer has been fixed, and Posadis should now work out-of-the-box, provided no other DNS server, such as the one of Microsoft Internet Connection Sharing, is running.... read more

Posadis works on 64-bits Alpha

The new m5 development version of the Posadis DNS server, which has just, right after the Posadis 0.40.2 release, been placed on the main branch, has been found to work on the 64-bits Alpha platform running Debian Linux 2.2

This means really a big step in Posadis development since probably other 64-bits platforms will also proove to work. Versions prior to the m5 series had problems with the sizeof(int) = sizeof(char*) = 4 assumption.... read more
