The ETH Zurich will be officially closed between Monday, 26th of December 2011 and Monday, 2nd of January 2012. During this time, we can only provide limited support. Please follow these rules to save us from superfluous work:

• Switch off printers
• Switch off your personal workstation and notebook except for the following:
• Do not switch off our managed Linux workstations.

We will try to follow our e-mail, but you may also have luck and meet some of us in our IRC channel.

Today, the 7th of December 2011, around 7pm, there will be a complete network interruption in the whole Department of Physics for about one hour. The central ETH IT Services (“Informatikdienste”) will replace the hardware of the core router to the HPx network zone (includes the HIT building).

Wireless LAN should not be affected, but as the servers will be offline, too, you won't have access to files or mails on the servers, i.e. don't expect to be able to work during the network downtime. The technicians will reconnect the servers first, so access to the servers from the outside of the Department or via WLAN will be restored earlier than 8pm. Workstations and printers will get network access back afterwards.

Today at 13:00 we had to reboot plompy, one of our LTSP terminal servers. We're sorry for any inconvenience. In order to prevent those terminal servers from clogging up memory in the future, we hereby announce the following maintenance reboot schedule:

plompy: first Sunday of each month, 02:00 am
plimpy: third Sunday of each month, 02:00 am

There will always be one functioning terminal server and upon login your thin client will choose the right one. Please don't forget to save your data when leaving for the weekend before those two Sunday dates (that's always a good idea anyways).

On Wednesday, 5th of October 2011, starting at 16:30, we will upgrade the operating system on several servers of our mail server cluster. This will result in temporary unavailability of most e-mail related services we provide: sending and receiving e-mails, mailing lists and webmail access.

Due to the maintenance e-mails may have some lag and arrive a few hours later than usual.

Update, 21:55: Upgrade of the incoming and IMAP/webmail/mailing list servers were successful. Everything is back to normal.

After 3 years in our current offices in HPT D floor we will move to our new (and hopefully final) location in HPT H. Tuesday to Thursday this week our services will be somewhat limited, but the helpdesk will be staffed at all times.

We're looking forward to welcoming you in our new quarters!

As some of you may have noticed there are a lot of viruses these days that arrive by e-mail and that slip through the virus filters. The current pattern involves ZIP attachments that contain executable code (EXE) inside it. The mail pretends to come from DHL, UPS, FedEx, or Xerox. We expect other fake senders like airline or hotel reservation systems to follow. We also expect to see infected PDF or MS office attachments.

The current viruses appear long before their signatures make it into the lists of the major anti-virus (AV) software. By the time the signature appears in the official lists the virus wave is usually already over. Be aware that no AV software can protect you reliably form viruses. All the AV software can do is keep the old known viruses at bay.

We are currently working hard to find such viruses and we keep our internal list of unofficial signatures. Once we recognize a new virus we clean them out of the user inboxes and move them to the SpamBox. However, we cannot garantee that we find all viruses.

Please be vigilant and do not trust attachments. ZIP and EXE are almost always bad. PDF are often OK but sometimes bad. Mail senders can be faked so make sure that you really expect an attachment from the sender.

We updated the hardware of 5 computers in the student computer room HPV F 7.1. With 4 GB of RAM and 3.0 Ghz processor from AMD they now have much more performance than the older ones. For identification, we have marked them with a blue label. These computers are available for public use within the usage policy while they're not being used for exercises.

Sunday Aug 21, 2011 around 2:30-2:40 pm the ETH Hönggerberg campus experienced a power outage. For some buildings (and/or power lines) the interruption was short and led to reboots of the affected computers. The HCI building remains without power as of this writing (4:20 pm). The server room at HIT D 13 seems not to have been affected by the power loss.

Some of our IT services are affected among them one of our DHCP servers and some of our backup servers. We will have to wait until power is restored in HCI to restart the affected services.

We apologize for the inconvenience.

Update 5:15 pm power is restored in HCI since about 4:30 pm.

This Thursday, the 7th of July 2011, around 7am, there will be a short network interruption in the whole Department of Physics. The central ETH IT Services ("Informatikdienste") will move our network zone to new hardware, necessary for some future services.

Additionally, the WLAN Landing Page of the "public" network will have a maintenance downtime from 7am to 8am.

On Monday, July 4, starting at 0700 we will upgrade our eGroupware installation to version 11.1. One of the most exciting features is the new ActiveSync plugin (incl. email push) that will also allow Android phones to sync calendar and contacts. We'll update our documentation as soon as 11.1 is running.

Update Monday 0930: the new version is installed and Android sync works. Read about it here.
