pacredir
pacredir - redirect pacman requests, assisted by avahi service discovery
By default every Arch Linux 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 to find
other instances and get the files there if available.
Requirements
To compile and run pacredir you need:
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, pacdbserve and pacredir, open TCP
ports 7078 and 7079 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 localhost: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 file found on
the local network. To make sure you really do have the latest files run
pacman -Syu twice.
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.
