The hardworking folks over at clamav.net have released a minor 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 as this is only a bugfix release for ClamAV.

I’ve updated my main test server that runs Snow Leopard and I haven’t noticed any strange behavior or errors, when looking at the usual suspects (like postfix and it’s configuration).

If you want to read more on what is affected in the updates I would suggest reading the Apple support site for the (security) update. It’s mainly fixing a problem with AFP which is not something we use.

I will update more machines later on, I only had time for one now, but I didn’t want to keep you all waiting too long.

This is a Security Update which solves the problem with the malicious PDF’s that plagued the iPhone/iPad as well. Besides solving this issue there are some minor fixes. There are no changes to any of our software (yes even postfix is unaffected!) so you can run this without any problem. Read more about it in Apple’s Knowledge base article. All my test and production server are now safe and still working perfectly.

I’ve updated all my machines that run Snow Leopard with the update and I haven’t noticed any strange behavior or errors.

If you want to read more on what is affected in the updates I would suggest reading the Apple support site for the (security) update.

There are some reports on changes in the firewall which might affect the workings of your server if you are using the default firewall configuration. I use noobproof to configure my firewalls. It has a better level of control.

Update: the postfix binary is replaced and you need to run a “sudo make install” from the last version you used. This is a reminder on why you keep the compiled stuff lying around on the server and not clean it up after installation.

Sorry that I’m later than I’m supposed to be with this blogpost, but my new day job needs all the attention at the moment. The good news is there are not much problems when you update your Mac with the latest security update. Read more about it in Apple’s Knowledge base article.

On Leopard there is a small known issue with postfix. To correct it 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
sudo postfix start

And all should be fine. If you find another issue please use the comments.
