Mac OS X update 10.6.8 and Security Update 2011-004

I’ve just installed the updates on all my test machines running Snow Leopard 10.6.7 and Leopard 10.5.8 before running it on my production server. I did a couple of tests on the machines and could not see an immediate problem on Snow Leopard. Therefore I’m happy to inform you that the Mac OS X 10.6.8 update does not introduce any problem for our setup.

The Security Update 2011-004 however does change Leopard. I’ve noticed that it replace the postfix binaries and adds Apple’s idea of a security feature to the configuration file. To correct the binaries, go to your latest postfix source directory from which you installed it last and run

sudo make install

For the changed configuration please comment out or delete the following line from ‘/etc/postfix/main.cf‘:

inet_interfaces = localhost

Restart postfix (reloading config does not work) with:

sudo postfix stop

Postfix should restart automatically (if not run “sudo postfix start”).

This is expected to be the last update before Lion and I’ve got everything lined up to test the upgrade to Lion and a new install on that same platform. I hope to be able to tell you what the results will be as soon as possible.

MySQL released 5.5.13

Somehow due to the speed of the internet and my recent vacation I got sidetracked and completely missed some MySQL updates. MySQL has released a new version of the 5.5.x branch which is already usuable in our setup when you read this blogpost. It works perfectly on my test machine. It includes several high-impact changes to address scalability and performance issues in MySQL Server. Read the release notes for all the details.

Luckily the problem with the unlinked libraries that caused problems during compilation with 5.5.10 has gone.

Read this documentation on how to ugrade this version using the package installer of MySQL.

Upgrading Clamav to 0.97.1

The hardworking folks over at clamav.net have released an upgrade to their virus scanning software. Upgrading is relatively easy and straight forward. All that needs to be done is remove the old version and install the new.

You can check the instructions on what to do here Upgrading ClamAV.

There is no need to reconfigure anything. This is a bugfix release.

Updating amavisd-new

For those of you who decided to install the ClamAV virus scanner and SpamAssassin system on their mail servers, there is an update to the amavsd-new daemon that glues the whole setup together.

The instructions for the update are available here Updating amavisd-new.

There is no reconfiguring necessary, as this is a bugfix update.
