How to configure the Charité proxy and ntp server on self-managed workstations

Linux, Mac and Windows devices in the Charité network that are not centrally managed by IT must configure the Charité proxy server to connect to the Internet:

APT (Debian/Ubuntu)
/etc/apt/apt.conf

Acquire::http::Proxy "http://proxy.charite.de:8080";
Acquire::https::Proxy "http://proxy.charite.de:8080";

Terminal (Unix/Mac)
/etc/environment (global)   or   .bashrc / .zshrc (local)

export http_proxy="http://proxy.charite.de:8080"
export https_proxy="http://proxy.charite.de:8080"

Windows System

netsh winhttp set proxy http://proxy.charite.de:8080

Conda

conda config --set proxy_servers.http http://proxy.charite.de:8080
conda config --set proxy_servers.https http://proxy.charite.de:8080

Python PyPI

pip config set global.proxy http://proxy.charite.de:8080

NPM

npm config set proxy http://proxy.charite.de:8080
npm config set https-proxy http://proxy.charite.de:8080

Docker

~/.docker/config.json

{
 "proxies": {
   "default": {
     "httpProxy": "http://proxy.charite.de:8080",
     "httpsProxy": "http://proxy.charite.de:8080",
     "noProxy": ".charite.de,127.0.0.0/8"
   }
 }
}

Time-Server (NTP)
/etc/systemd/timesyncd.conf (Unix)

[TIME]
NTP=time.charite.de

Windows: Control Panel → Date and Time → Internet Time: change address to time.charite.de
