Using HTTP Proxy Server - Debian 11

Due to current events that sometimes cost me time I would like to have some information about Debian 11 in this post and write down the use of proxy servers as required to see again here. So also other of my notes I make them publicly accessible directly here.

Configure proxy servers for using Apt (package manager)

To install packages, apt requires information about proxy Servers to connect to target servers can.
If not done in the setup, this can be easily reconfigured

vi /etc/apt/apt.conf

Acquire::http::Proxy "http://<<ip>>:<<port>>";
oder (wenn Userdaten benötigt werden)
Acquire::http::Proxy "http://<<username>>:<<password>>@<<ip>>:<<port>>";

(Die jeweiligen "<<" und ">>" sind ebenfalls zu entfernen)

Set system variables (automatically used by many programs)

export http_server=http://<<username>>:<<password>>@<<ip>>:<<port>>/ 
export https_server=https://<<username>>:<<password>>@<<ip>>:<<port>>/

Configuration of proxy in the bash

vi /etc/bash.bashrc
export http_proxy=http://<<USERNAME>>:<<PASSWORD>>@<<SERVER>>:<<PORT>>/

Configuration of proxy in the “enviroment” file

vi /etc/environment/

http_proxy="http://<<user>>:<<password>>@<<ip>>:<<port>>/
https_proxy="http://<<user>>:<<password>>@<<ip>>:<<port>>/

Using Curl Proxy automatically

vi ~/.bashrc

alias curl="curl -x <<username>>:<<password>>@<<ip>>:<<port>>"

ALTERNATIV

vi ~/.curlrc
proxy = <<username>>:<<password>>@<<ip>>:<<port>>

Use Service Drop-In (e.g. for containerD)

mkdir -p /etc/systemd/system/containerd.service.d

vi /etc/systemd/system/containerd.service.d/http-proxy.conf

[Service]
Environment="HTTP_PROXY=http://<<ip>>:<<port>>

This also works analogously with NO_PROXY and HTTPS_PROXY

Finally, the respective service and the daemon must be restarted so that all changes are taken over

sudo systemctl daemon-reload
sudo service containerD restart

When entering

As always, I give no guarantee that this information is correct, or is best suited or complete.
