- apt-proxy-detect
- Why this is needed?
- How does it look?
- How to install?
- How does it work?
- Caching found proxies.
- Debugging
Auto detection of apt proxies in the LAN, caching and checking status of it.
In one sentence, set or let it find your proxies from work, school or from at home, it does not matter, it takes the working ones or none (direct connect), where ever you are.
apt-proxy-detect can be used as on clients to detect apt-cacher-ng or squid-deb-proxy in your network.
Spending 2023 time on this topic sound/reads quite strange but up to now i struggle with some problems within the solutions i found so far.
Issues:
- No reliable detect proxies via mDns. (Timeouts, not found)
- No caching of the found proxies.
- No check if the found proxy works for the requested target.
- No longer active maintained (deprecated warnings all over the place)
What do you get?
- Proxy detection via
- avahi
- set defaults
- caching of URL specific working proxy (or none if none works)
- caching over reboot if possible
- allow mixture of allowed and non allowed urls (no need for direct declaration)
Example output:
dev@dev:~$ apt-proxy-detect.sh
usage: apt-proxy-detect.sh <defaults|set-default|url for proxy>
defaults ... list default proxies
set-default <proxy1>,<proxy2> ... set default proxies
url for proxy ... this is the url a proxy is tested for
or with setting default proxies:
dev@dev:~$ apt-proxy-detect.sh set-default https://192.168.0.2:8093,https://192.168.0.3:4544,http://192.168.0.27:8000
defining default proxies...
proxy: https://192.168.0.2:8093
proxy: https://192.168.0.3:4544
proxy: http://192.168.0.27:8000
saved.
or show default proxies:
dev@dev:~$ apt-proxy-detect.sh defaults
proxy: https://192.168.0.2:8093
proxy: https://192.168.0.3:4544
proxy: http://192.168.0.27:8000
or with specific url for checking (failing+avahi detection):
dev@dev:~$ apt-proxy-detect.sh github.xyz

if you like to specify a branch do it like:
curl -s https://raw.githubusercontent.com/hastmu/apt-proxy-detect/main/install.deb.sh | sudo BRANCH=main bash
Required packages can be installed via:
sudo apt install -y coreutils grep sed wget avahi-utils
So the quickest way is:
curl -s https://raw.githubusercontent.com/hastmu/apt-proxy-detect/main/install.sh | sudo bash
looks like:
dev@dev:~$ curl -s https://raw.githubusercontent.com/hastmu/apt-proxy-detect/main/install.sh | sudo bash
- check dependencies...
- download latest to: /usr/local/bin/apt-proxy-detect.sh
- BRANCH [main]
- set permissions to a+rx
- create/updating /etc/apt/apt.conf.d/30apt-proxy-detect.conf
if you like to specify a branch do it like:
curl -s https://raw.githubusercontent.com/hastmu/apt-proxy-detect/main/install.sh | sudo BRANCH=main bash
or you just download the install.sh and run it locally.
The apt.conf.d entry makes apt aware of the tool which is then call during "apt update", for some reason most of the other tools are not aware that you get the target URL as parameter for this call.
This URL is the proxy check URL to confirm that the found or cached proxy is working with this dedicated URL as some proxies may have white/black lists or just not got configured right or outdated for the new stuff to be checked out.
In case a proxy is not serving the URL it is drop for this dedicated URL. Latest version also cache the none-proxy state for 60 seconds, accepting the fact that there is currently no proxy around which can serve the request.
The found (via avahi-browse _apt_proxy._tcp) proxies are cached in case this has the wrong owner it is ignored and a waring is issued.
Thats it. Enjoy.
Latest version include the capability to cache the found proxies persistent over reboot. Default locations per user in this order (in case this is not writable fall back to the next):
- _apt: /var/lib/apt/lists/auxfiles/
- *: $HOME/.config/
- *: /tmp/
In case of issues you can set "DEBUG_APT_PROXY_DETECT" to get all details, like e.g.:
export DEBUG_APT_PROXY_DETECT=1
sudo apt update
