ISG News has posted a new item, 'Groupware upgrade'
On Thursday, July 21, starting at 0700 we will upgrade our groupware solution.
The update is expected to take approximately one hour. As this upgrade will be a
major one (version 14.3 to 16.1), you might notice a few changes. In
particular:
if you didn't log out before we start the upgrade, your browser might be in an
inconsistent state and the new version might refuse to work. Just log out
manually in this case.
if you're using the ActiveSync/eSync/Exchange protocol for calendar
synchronization, you will have to recreate your sync account on your (mobile)
device. Just delete your existing account on the device (your groupware data
will still be on our server) and add it again (see documentation). We're sorry
for the inconvenience, but the synchronization code was rewritten to be faster
and more stable and is not compatible to existing accounts. We have tried to
identify all current ActiveSync users and will inform them via email.
the web interface will get a new look (see screenshot)
We have thoroughly tested the new version internally. If you find any problems
after the upgrade, please get in touch. Thanks.

ISG News has posted a new item, 'Scheduled Maintenance Downtime Starting on
Thursday, 14th of April, 5pm'
Due to required changes to our network infrastructure and some hardware
maintenance, we're scheduling a maintenance downtime for most D-PHYS servers
starting on Thursday, 14th of April 2016, at 5pm. The downtime will last several
hours and single services may be down for longer than others or will be down
multiple times in a row.
We'll update this posting as soon as things are back to normal.
Most D-PHYS services will be affected by that downtime, especially file servers
and e-mail services, but also some virtual machines and most websites hosted by
ISG D-PHYS are affected. (http://www.phys.ethz.ch/ and other AEM-hosted websites
are not affected.)
E-mails coming in during the downtime will be held on the sender's side and will
arrive at D-PHYS with a delay. Sending e-mails won't be possible during the
downtime either.
After the migration we will benefit from a faster and more reliable network
connection to our servers.

ISG News has posted a new item, '2015 in review'
This post is meant to give you a short overview of what has been accomplished in
D-PHYS IT by ISG this year. We’ve been hard at work to further improve and
extend our services for you, our customers. Some highlights of 2015:
new team members: both Christian Ringger and Christian Schneider joined ISG
this year and have already made significant contributions to our setup.
new D-PHYS website: the department website moved from the self-hosted Zope
system into the ETH-wide AEM/CQ5 content management system. While the hard work
of migrating all the content was done by Andreas Trabesinger, we had to sort out
a lot of technical details to ensure a smooth transition and to keep D-PHYS's
various web services operational.
Printing: the majority of the department's printers have been migrated to the
new pia printing system. We are now waiting for Informatikdienste to support
student printing in order to complete the project.
Storage: in 2015 the disk space occupied by data and backup grew from 685 TiB
to 929 TiB, further increasing the yearly growth rate. We are also preparing to
keep an off-site disaster recovery copy of D-PHYS data on tape.
Outages: apart from a hardware failure of our mail server on December 2nd and a
short interruption on July 2nd our system have been very stable this year.
System upgrades: 2015 brought OS upgrades for almost every system: Debian Jessie
on many servers, OS X 10.11 for the Macs, Ubuntu 14.04 on the Linux workstations
and the first pilot installations of our new Windows 10 setup.
Core services: a lot of infrastructure work has happened in the background to
ensure smooth operation and seamless growth of our services in the future.
Examples are: more IPv6 work, 802.1x / NAC in our network, a new network zone in
the server rooms, an upgrade of our iPXE boot screen and enhanced monitoring.
IT security: we participate in and support the ETH-wide IT security initiative.
Happy Holidays and see you in 2016!

ISG News has posted a new item, 'Results of IT services survey'
Thank you to all of you who participated in our IT services survey in late
October. More than one third of you completed the questionnaire and the feedback
has been extremely positive. The Department Head and ISG have evaluated the
results and would like to say thanks to everybody involved.
We have received many helpful comments that deserve an answer. Since the survey
was anonymous, we have no way of getting back to each responder individually, so
we compiled the questions, answers and comments on a nifty website that we
invite you to visit:
https://nic.phys.ethz.ch/it-survey/
You can browse the results, read the comments and click on the little speech
bubbles to read our answers. There are a couple of topics that are sufficiently
common and generic that we would like to address them here:
* WiFi: yes we know it's not great, but we cannot immediately fix it as it is a
service of Informatikdienste. We are working together with our colleagues of ID
to resolve the problems and improve WiFi service on the campus.
* many of the wishes and problems raised in your comments actually have already
been solved by us. Also,
* there seems to be a positive correlation between how often people contact us
and their satisfaction with out services. So:
Please talk to us! We can only help you if you tell us about your problem, and
we hate unsolved problems. So we're going to try hard to fix them.
Thanks for you attention and we're looking forward to serving you in the
future.

ISG News has posted a new item, 'New SSH Host Keys on Managed Linux Machines and
partial BackupPC outage'
After several years it was time to update the SSH host keys of our managed Linux
machines. Therefore, if you reconnect with SSH, you might get a warning similar
to this one:
ssh login.phys.ethz.ch
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
36:04:d8:3d:89:a2:76:19:ef:b6:f0:0a:f2:5c:81:a3.
Please contact your system administrator.
Add correct host key in ~/.ssh/known_hosts to get rid of this message.
Offending key in ~/.ssh/known_hosts:1
RSA host key for login.phys.ethz.ch has changed and you have requested strict
checking.
Host key verification failed.
This is because your computer has memorized the previous host key and is bailing
because the current one is different. This mechanism is designed to prevent
users from man-in-the-middle attacks. In our case it can be treated as a mere
notification that the SSH key has changed.
In order to get rid of this warning, you simply need to delete the old key from
your ~/.ssh/known_hosts file. This can be done either by deleting the entry
manually or with the following command
ssh-keygen -R login.phys.ethz.ch
for the machine you try to ssh into.
On the next SSH connection you will be prompted to accept the new key. Power
users may also download the full list of SSH keys of all our managed Linux
computers.
On a side note, one of our BackupPC servers is currently offline because of a
broken capacitor on the mainboard. Hosts connected to backuppc2.phys.ethz.ch
will not be able to make backups or restore files until the broken part has been
repaired.

In order to perform system-level maintenance work, we schedule a maintenance
downtime of the D-PHYS mail server today (Thursday, 2nd of July 2015) starting
at 17:00. We expect the downtime to take about one hour.
During the downtime all mail services (sending mail, receiving mail, accessing
mailboxes, webmail, etc.) will be unavailable. Mails sent to D-PHYS users during
the downtime will be held back on the sending side and will be delivered after
the downtime.
We will post an update as soon as mail services are back.

ISG News has posted a new item, 'Windows Server 2003 reaches its End-of-Life on
July 2015'
Microsoft will provide a final bunch of patches for Windows Server 2003 on July
14th. 2015. After then, no more security and stability fixes are going to be
released. This means that still running Windows Server 2003 machines conflict
with the ETH Bot (Acceptable Use Policy for Telematics) which requires that
every computer connected to the ETH network must be fully updated and secured.
The central IT security group of ETHZ continuously inspects the network streams
for signatures of XP and Windows Server 2003 computers. If you have a running
Windows Server 2003 machine connected to the public network, please migrate the
operating system to a newer version i.e Windows Server 2012.
If you have any questions or need help please do not hesitate to contact the ISG

ISG News has posted a new item, 'Used hardware bargain bin / yard sale'
ISG sits on a pile of older hardware that for various reasons cannot be used in
our setup any more but that various people have expressed interest in and that
still might be useful for certain scenarios (e.g. lab use or tinkering at home).
We will therefore host two grab-your-used-piece-of-hardware sessions:
Window 1: hardware outside of the ETH live cycle, mainly old computers
(PowerPC-Macs and PCs) and TFT monitors, free of charge for both ETH-internal
and private use: Wed Apr 22 - Fri Apr 24 in HPT H floor
Window 2: not-quite-as-old hardware, mostly TFT monitors and printers, free of
charge for ETH-internal use, prices for private use according to the rules: Wed
Apr 29 and Thu Fri 30 in HPT H floor
As usual, some rules apply:
this goes to all D-PHYS members
no registration necessary. Just come by and take whatever is left.
all items come as they are. We do not have any details or specifications
there’s no warranty or service whatsoever. All devices have successfully been
turned on, but that’s it
if your item doesn’t turn on, you can bring it back within 5 days and get a
full refund (if it wasn't free in the first place)
no OS, no software, no manual, no keyboard, often no cables. You get one piece
of hardware. All HDs are blank
all proceeds go to the D-PHYS funds, not ISG
if you have no use for a computer without OS or software, don’t come
shopping
bring cash
note that the printers are not meant to undermine the migration to the new
printing system! We will not connect those printers to our old print server
