Working at FZI

If you are writing your Bachelors or Masters thesis or if you're a HiWi at FZI, you might find the following useful.

OpenVPN ¶

Download the client.ovpn from the website your advisor gives you. This website can only be accessed outside of FZI and needs to be accessed by https:// - http:// does not work.
Run it with sudo openvpn --config client.ovpn
Verify it with ifconfig - there should be tun0

WLAN ¶

Wi-Fi Security: WPA & WPA2 Enterprise; PEAP; No CA certificate required; MSCHAPv2
IPv4: Automatic (DHCP)
IPv6: Ignore

Python Virtalenv ¶

You don't have root access. However, you can install Python packages via virtualenv (at nobackup - you don't need this to be backed up and you want to have less limitations on your venv size):

$ mkdir ml-venv
$ cd ~/ml-venv
$ virtualenv ml
$ source ml/bin/activate

Add the source ml/bin/activate (with the absolute path) to your ~/.bashrc. Now you can use pip install ... to install whatever you need in which version you need.

cuDNN ¶

Add

export LD_LIBRARY_PATH=/fzi/ids/thoma/nobackup/cuda/lib64/

to your ~/.bashrc. If that doesn't exist anymore, just download cuDNN and adjust the path to the lib64 folder.

Blame users ¶

With nvidia-smi you can see which processes currently use the graphics card:

+-----------------------------------------------------------------------------+
| NVIDIA-SMI 361.93.02              Driver Version: 361.93.02                 |
|-------------------------------+----------------------+----------------------+

| Fan  Temp  Perf  Pwr:Usage/Cap|         Memory-Usage | GPU-Util  Compute M. |
|===============================+======================+======================|

+-------------------------------+----------------------+----------------------+

+-----------------------------------------------------------------------------+
| Processes:                                                       GPU Memory |
|  GPU       PID  Type  Process name                               Usage      |
|=============================================================================|
|    0      2473    G   /usr/bin/X                                      24MiB |

+-----------------------------------------------------------------------------+

But it doesn't tell you how long the process is already running and which user started it. With

$ ps -p 32756 -o user -o time

(replace 32756 by the process ID, of course) you can find the user name and how long the process is running.

Send files ¶

See Linux Commands for Working from home and How to copy files from one machine to another using ssh.

Copy foo.txt from localhost to a remote host:

$ scp foo.txt yourusername@remotehost.com:/home/remote/dir

Disk usage ¶

$ quota -s -u user1
$ df -h .
$ du -h .

SSH / screen ¶

users to see who is currently logged in.

Personalabteilung ¶

If you want to get your money back from the code card, you have to go to the "Personalabteilung". They have very limited opening times:
