We just deployed new SSL certificates for some of our services. Sending e-mails via our mail server no longer requires the import of our root CA certificate beforehand, but may require a restart of your e-mail client. Internal websites (like account management and password changing) or websites which are hosted by us and don't end in .ethz.ch got new certificates signed by our new root CA certificate. To avoid annoying and irritating warnings, we recommend you import our root CA certificate into your web browser.

The new root certificate will be installed in the web browsers on our managed workstations within the next days, too.

Now that the dust has settled a bit, we would like to give a status update after the print server migration. Somewhat contrary to popular belief, the overall situation with printing has improved quite a lot. Most combinations of operating systems, client programs, file formats and printers work very well, with two notable exceptions:

• Mac OS X 10.6.7: printing some PDFs from non-Adobe programs on some printers fails. We're working on a solution. Either use Adobe Reader/Acrobat or print on any other printer. This problem is introduced with the 10.6.7 update. You'll have to use the Acroread workaround until we find a solution.  SOLVED: Apple released an official patch to fix the problems with fonts. Please update your computer.
• Macs: the LPD way of printing (readme) currently does not work. Again, we're working on it. Use CUPS in the meantime. SOLVED

As a reminder, please let us know immediately if apart from the above-mentioned cases you still experience printing issues.

The new print server solved many of the problems that were troubling you (and us) in the past. Unfortunately, it seems it also introduced a couple of new ones. In order for us to be able to address them, it is very important that we know about them in the first place. We hadn't seen those issues in our months-long tests, otherwise we wouldn't have deployed the new server. So, pretty please with sugar on top, call us immediately if your print job does not come out as expected. A problem description like "it hasn't been working for weeks" does not help anyone. Please call us, we're working hard to find and eliminate those issues. Thank you.

On Wednesday, the 6th of April 2011, starting around 5pm we will upgrade the operating system on the two D-PHYS DHCP servers. This should not cause any interruptions for computers which are already online, but computers which connect to our network between 5pm and 6pm may not get an IP address assigned immediately. As these computers mostly will be mobile devices, we suggest to switch to the wireless network instead for that evening.

We know printing is not always fun, and we hear your complaints. During the past few months we have been busy setting up a new print server that should solve most of today's problems (hopefully). We will deploy the new system on

Monday, April 4, at 07:30

The only change for you should be faster and more reliable printing. If you do experience any problems when printing, please let us know immediately so we can fix it.

Update 08:45 DNS confusion about old/new print server, we'll have to wait for the DNS cache to flush

Update April 5, 16:10 migration is done
