pacredir ======== **pacredir - redirect pacman requests, assisted by avahi service discovery** By default every [Arch Linux](https://www.archlinux.org/) installation downloads its package files from online mirrors, transferring all the bits via WAN connection. But often other Arch systems may be around that already have the files available on local storage - just a fast LAN connection away. This is where `pacredir` can help. It uses [Avahi](http://avahi.org/) to find other instances and get the files there if available. Requirements ------------ To compile and run `pacredir` you need: * [systemd](https://www.github.com/systemd/systemd) * [avahi](https://avahi.org/) * [libmicrohttpd](https://www.gnu.org/software/libmicrohttpd/) * [curl](https://curl.haxx.se/) * [iniparser](https://github.com/ndevilla/iniparser) * [darkhttpd](https://unix4lyfe.org/darkhttpd/) * [markdown](https://daringfireball.net/projects/markdown/) (HTML documentation) `Arch Linux` installs development files for the packages by default, so no additional development packages are required. Build and install ----------------- Building and installing is very easy. Just run: > make followed by: > make install This will place an executable at `/usr/bin/pacredir`, documentation can be found in `/usr/share/doc/pacredir/`. Additionally systemd service files are installed to `/usr/lib/systemd/system/` and avahi service files go to `/etc/avahi/services/`. Usage ----- Enable systemd services `pacserve` and `pacredir`, open TCP port `7078` and add the following line to your repository definitions in `pacman.conf`: > Include = /etc/pacman.d/pacredir Do not worry if `pacman` reports: > error: failed retrieving file 'core.db' from 127.0.0.1:7077 : The > requested URL returned error: 404 Not Found This is ok, it just tells `pacman` that `pacredir` could not find a file and downloading it from an official server is required. Please note that `pacredir` redirects to the most recent database file found on the local network if it is not too old (currently 24 hours). To make sure you really do have the latest files run `pacman -Syu` *twice*. To get a better idea what happens in the background have a look at [the request flow chart](FLOW.md). Security -------- There is no security within this project, information and file content is transferred unencrypted and unverified. Anybody is free to serve broken and/or malicious files to you, but this is by design. So make sure `pacman` is configured to check signatures! It will then detect if anything goes wrong.
