You can access your files that you have on the server via Samba (recommended for administration staff and also for all macOS users) or via SSH (ssh, sftp, rsync, unison, …)

Access via Samba (VPN needed!)

Connect to:

• smb://shares.math.ethz.ch (macOS & Linux)
• \\shares.math.ethz.ch (Windows)

and login with your eth-username and your e-mail password.

MacOS

Select the Finder, in the menu Go, click on Connect to server…, enter the address smb://shares.math.ethz.ch, click on Connect and authenticate. Afterwards you will be prompted to select a “volume” like “your-eth-username”, “www” or “share-xyz”.

Linux

Open Files (Nautilus), click on Other Locations, enter the address

• smb://shares.math.ethz.ch/NAME_OF_THE_SHARE

click on Connect and authenticate.

Windows

Click on the Start button, enter run, enter the address \\shares.math.ethz.ch and authenticate. Afterwards you will be prompted to select a share like “your-eth-username”, “www” or “share-xyz”.

Access via SSH

The official SSH/SFTP server of the D-MATH is sftpmath.math.ethz.ch but with the “home office” setup (in particular using the “math-guest” or the “math-clients” VPN) you can access almost all linux computers of the department, in particular all Central Clients (ex. ion-*, ada-*).

Please be careful when using external cloud services (such as Overleaf, Dropbox, DeepL, …) and try to make regular backups on your local device (laptop) or, even better, on the departmental file server.

The usage of some external cloud services has been approved (at least partially) by the CISO and the central IT services.

Here you’ll find more information:

All the accounts of D-MATH members are going to be migrated to the Microsoft cloud in the week of October 21 – 25, 2024.

This means that all the mail accounts will have to be reconfigured, i.e. the old mail account has to be deleted from your mail application and then the new account has to be added. You’ll find links on how to do that below.

The new address for webmail is: https://outlook.office.com

• https://github.com/moodlehq
• https://hub.docker.com/r/moodlehq/moodle-php-apache

Develop moodle

• https://github.com/moodlehq/moodle-docker

The following setup can be used to setup a moodle development environment, with rootless podman:

# D-MATH link podman-compose
ln -s /usr/bin/podman-compose ~/bin/docker-compose

# D-MATH clone moodle-docker repo
git clone https://github.com/moodlehq/moodle-docker.git
cd moodle-docker

# D-MATH set variables
export MOODLE_DOCKER_DB_PORT=15432
export MOODLE_DOCKER_APP_VERSION=18080
export MOODLE_DOCKER_SELENIUM_VNC_PORT=15900
export MOODLE_DOCKER_WEB_PORT=18000

# Change ./moodle to your /path/to/moodle if you already have it checked out
export MOODLE_DOCKER_WWWROOT=./moodle

# D-MATH add custom configuration
cat <<EOF > local.yml
services:
  webserver:
    volumes:
      - "${MOODLE_DOCKER_WWWROOT}/../moodledata:/var/www/moodledata"
  db:
    environment:
      PGDATA: /var/lib/postgresql/data/pgdata
    volumes:
      - "${MOODLE_DOCKER_WWWROOT}/../database:/var/lib/postgresql/data"
EOF

# Choose a db server (Currently supported: pgsql, mariadb, mysql, mssql, oracle)
export MOODLE_DOCKER_DB=pgsql

# D-MATH creating files with group access for moodle code
umask 007

# Get Moodle code, you could select another version branch (skip this if you already got the code)
git clone -b MOODLE_404_STABLE git://git.moodle.org/moodle.git $MOODLE_DOCKER_WWWROOT

# D-MATH add folder for moodle data
mkdir moodledata
mkdir database

# D-MATH setgid for automatic setting group permission
chmod 2770 moodle
chmod 2770 moodledata
chmod 2770 database

# Ensure customized config.php for the Docker containers is in place
cp config.docker-template.php $MOODLE_DOCKER_WWWROOT/config.php

# D-MATH set the permission to 33 inside the container for moodle code
podman unshare chown 33 -R moodle
podman unshare chown 33 -R moodledata
podman unshare chown 999 -R database

# Start up containers, choose docker.io to download the images
bin/moodle-docker-compose up -d

# Shut down and destroy containers
#bin/moodle-docker-compose down

Above we set the webserver port to 18000 so this means you now need connect to http://localhost:18000 in your browser to see the application.

Volume Permissions

If you have added new files from outside the container, you need to re-apply the correct permissions. Let’s say you have added files inside the moodle folder, then you need to run the following command:

# set the permission to 33 
podman unshare chown 33 -R moodle

Visual Studio Code

To prevent the above Volume Permission problem, you can connect your locally installed Visual Studio Code to the running container:

• https://code.visualstudio.com/docs/devcontainers/attach-container

• Open Visual Studio Code
• Hit F1
• Search for Attach to Running Container
• Choose the webserver container
• Now open the folder /var/www/html

If you need to run some commands in the container:

• After being connected to the container
• Hit Ctrl+`

If you want to develop something for kubernetes, you may need to run minikube. This can be done on our linux installations, the following commands should start a working “kubernetes cluster” on your installation:

mkdir ~/bin/

wget https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 -O ~/bin/minikube
chmod 755 ~/bin/minikube

cd ~/bin/
./minikube config set rootless true
./minikube config set driver podman
./minikube config set container-runtime containerd

./minikube start --cni calico

After minikube has started you can check all running pods with the following:

minikube kubectl -- get pods -A

You can also install kubectl and helm in your ~/bin if you like:

cd ~/bin/

curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"

export HELM_INSTALL_DIR=~/bin; export USE_SUDO=false; curl https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 | bash

We offer the following standard hardware to our staff:

• Linux desktop computer: e.g. Esprimo Q958 with 8-Core Intel i7
• Mac desktop computer: e.g. Mac Mini with 6-Core Intel i5 or Apple Silicon
• Linux laptop computer: e.g. ThinkPad X1 Yoga, ev. ThinkPad X1 Carbon; or a Laptop that is up to 4 years old
• Mac laptop computer: e.g. MacBook Pro 14″ with Apple Silicon; or a MacBook Pro that is up to 4 years old

Additionally you can get 1 screen (EIZO 24″ or 27″) (upon request 2, if supported by the hardware) and a docking station and some adaptors if you have a laptop.

You can get a desktop computer more or less immediately (1-2 days). New laptops are usually ordered during the Neptun period, ie. 2 times a year (middle of February – middle of March and September). They have a delivery time of 6-10 weeks (or even longer).

If you decide to have a laptop computer and we don’t have one in stock, you can start with a desktop computer and change later or you can use your private laptop computer until the one provided by the department has arrived.

Rules

We have the following rules concerning laptops:

• PhD students should contact their supervisors about the choice of model and operating system (Fedora Linux or macOS)
• we only support Fedora Linux and macOS
• the laptop belongs to ETH (as it is paid by D-MATH)
• the laptop is managed and installed by ISG D-MATH, but you’re allowed to install additional software (but e.g. not a different operating system)
• the laptop should be handled with care
• repairs etc. are handled by ISG D-MATH
• you can have either a laptop or a desktop; you can have an external screen, keyboard and mouse with the laptop
• you don’t necessarily get a new laptop, we use old laptops again
• there is no backup of the data on a laptop unless you make a backup (we can help with that)
