OpenBSD 3.6 released.

Recommended Posts

OpenBSD (which is Unix) just realesed their new version (october 29), 3.6.

Actually pretty impressive improvements from their previous version, which was excellent...


New functionality:

* A cleaned up DHCP server and client implementation, now featuring privilege separation and safe defaults.

* A new NTP daemon written from scratch, which ought to fit the needs of most NTP users.

* pfctl(8) now provides a rules optimizer to help improve filtering speed.

* The packet filter, pf(4), now supports nested anchors.

* tcpdrop(8), a command to drop TCP connections.

* The NMBCLUSTERS option has been eliminated, replaced by a sysctl with higher default values on many platforms.

* Added support for cksum (three flavours), md4, sha256, sha384 and sha512 to the md5(1) command.

* Memory file systems created by the mount_mfs(8) command now can be populated immediately after creation.

* New hotplugd(8) daemon and hotplug(4) device that watch for newly attached devices.

* isakmpd(8) now supports NAT-traversal and Dead Peer Detection (RFC 3706).

* strtonum(3), a simple, robust and therefore safe function to convert strings to numbers, has been added.

* On the OpenBSD/sparc platform, StackGhost buffer overflow exploit protection has been added.

* A generic IEEE 802.11 framework has been added.


Also added to that were some improvements of OpenSSH. Specifically sshd now restarts every time a new connection like for example a shared library connection is established.

Actually, this concerns BSD's security...

Just read this article on Mi2g research, which every year looks at new releases of OSes and tests them for volnurabilities. This years research shows that BSD and OSX are among the best (surprise surprise, both of them are Unix based... never mind)

Anyways here is an exerpt from the article:

"The company estimates that worldwide economic damage in 2004 from these intrusions at between $103 and $126 billion.


Mi2g also concluded that environments running Mac OS X, as well as BSD Unix and Linux, have not experienced "any significant economic damage" from malware attacks such as viruses, worms and Trojan horses.


"Windows has become the most breached computing environment in the world, accounting for most of the productivity losses associated with malware ... proliferation. This is directly the result of very insignificant quantities of highly damaging mass-spreading malware being written for other computing environments like Linux, BSD and Mac OS X," said the report.


The company estimates that malware will cost organizations and individuals another $166 billion to $202 billion in 2004, including support costs, loss of business, bandwidth clogging and other costs. "
