Frequently Asked Questions
New machines are installed by us and then handed to the groups. For machines that we cannot install, e.g. because they have been delivered by the maker of an instrument, you need to tell us their MAC address and hostname.
Machines can be hooked into any network port, but will usually only work, after we switch the port to the correct network, because Linux, Windows and Laboratory machines are on different networks. To do this we need the network socket's identifier, which you can read off of the socket. The identifiers have the form 1.2.34/1-1, where everything before the slash is the room number, the number directly after the slash is the number of the network socket and the last number is the number of the port. The port number will be 1 or 2 and, if it is not labeled, 1 is left. If the socket number is missing, which can be the case for older sockets, it will be 1 as well.
There are a lot of printers in the department and many groups have multiple printers, so it's a good idea to ask on which printers to print. The printers in the student computer pools are
physik02 (bw) und
physikcol02 (colour) and need a ZEDAT print account with credit, which can be charged via a terminal in the computer pools.
You can print on the new centrally managed printers via the
followme queue. You can than collect your printer at any centrally managed printer after logging in with your ZEDAT account. To make that easier you can activate your door token for authentication at the printers at the Feinwerktechnik.
Documentation on using our printers with your own computers can be found in our Wiki.
Posters can be printer at the ZEDAT.
First of all, you should never reply to suspicious emails, click on links contained in such mails or open its attachments. Be careful with mails that you do not expect, that comes from people you have never had contact with or that are unusual for the sender. If in doubt, just ask us.
Emails can be very falsified very easily, since they are little more than text files in a certain format, that are exchanged between mail servers. A lot of servers are therefore extremely liberal in what they accept in their
Current malware can produce extraordinarily genuine looking phishing mails, but recently we had cases of easily-noticeable forgeries, notable for inconsistent names and addresses (John Doe <firstname.lastname@example.org>), usage of non-departmental mail addresses, linguistic mistakes and their content.
If you suspect to have received such mail, please send it to email@example.com by first saving the mail (usually right click on the mail and
Save as) and attaching it to your mail.
You need a ZEDAT account to log into the machines at the department. Once you have your account it needs to be whitelisted for usage at the physics department. This happens automatically for students, for new employees we need a note from your group (the group leader, IT coordinator or secretary).
ZEDAT deletes accounts shortly after people leave FU. If you have ongoing projects that make it necessary for you to keep your account with us, your account can be converted into a project account for the duration of the project. Talk to your group leader and us about converting your account in time.
Linux / HPC
There are multiple places where you can store files. There is your home directory,
/home/<username>, and "storage", available at
<username> is your username.
The quota for home is 2GB for students and 20GB for everyone else. Storage has a quota of 100GB for students and 500GB for everyone else.
The quota for the home directories is so small, because it is backed entirely by fast solid state drives whereas storage is backed by convential rotating rust. Just symlink directories in storage to your home if you need to access them more often.
Some FU forms (e.g. travel reimbursement and holiday forms) are PDFs using so-called XFA forms that are solely supported by Adobe Reader. Since Version 9 Adobe does not support running Adobe Reader in Linux environments. To allow filling out these forms we support the current Adobe Reader with Wine. You can start Adobe Reader using the
We install a lot of packages by default, probably the package is already installed. If not and the software is packaged for Debian, its sufficient to write an email to firstname.lastname@example.org with the package's name. You're also free to compile things to your hearts content in your home and the package managers of the usual programming languages have options to install packages to your home (e.g.
pip3 install --user).
Please write an email to email@example.com. We have already packaged most usualy software and it's enough to write an email and we will make the software available for you in the software center. In the case of unsualy software we will install it via remote support or come to your desktop.
No, we don't offer our own mail services, email is handled by ZEDAT. However, every user at the physics departments gets an email address of the form
<username>@physik.fu-berlin.de, that is forwarded to the ZEDAT address. Furthermore we offer several mailing lists.
There are several mailing lists at the physics department. The most important ones are:
- firstname.lastname@example.org, going to all the department's students,
- email@example.com, going to all employees,
- firstname.lastname@example.org, going to everyone at the department, and
- email@example.com, going to the student union (Fachschaftsinitiative).
All lists are moderated. Please write your mails to the narrowest possible circle of recipients as the lists are extremely large. The all list should be used as rarely as possible. Mails with attachments larger than 500kB will be rejected outright.
The studies list is the right list for announcements about available master thesis topics and PhD positions.
Also, every group has their own group mailing list
Matrix (chat platform)
Since version 13.0 Gitlab has started to warn users about logins from unknown locations via mail. Most users don't notice this, because they never log out, but users who regularly sign out might find these mails unsettling, since IP addresses on home lines change daily which is why these mails might occur on every login.
If the IP address of the login is the one of your line (which you can check for example on the config page of your router) there is nothing to worry about.
The issue was resolved for Gitlab 13.3. Please let us know, if you continue to get this warning.
