Pacserve allows to easily share pacman packages between computers. This is very useful, if you have a slow internet conenction, but multiple machines running Arch Linux.

Installation

You can either install pacserve manually from the AUR, or with the following method.

From Xyne's repository

Xyne is the author of pacserve, you can directly use his repository by adding the following to your pacman.conf.

/etc/pacman.conf
...
[xyne-x86_64]
# A repo for Xyne's own projects: http://xyne.archlinux.ca/projects/
SigLevel = Required
Server   = http://xyne.archlinux.ca/repos/xyne

Make sure that you have replaced x86_64 with i686 or any depending on your architecture. Then install the package:

# pacman -Sy pacserve

Finally enable and start the daemon:

# systemctl enable pacserve.service
# systemctl start pacserve.service

In case you use iptables, you will probably want to start the pacserve-ports service, too.

Standalone usage

Instead of pacman, use the pacsrv wrapper to perform an update, install packages and so on. It will automatically download all packages from the LAN, if someone hosts them with pacserve there. Otherwise it will just download them from the internet mirrors, as usually. For example:

pacsrv -Syu
pacsrv -S openssh

Configure Pacman to use Pacserve

If you are always running the pacserve daemon and want pacman to use it without the wrapper, add the following line below each repository in /etc/pacman.conf:

 Include = /etc/pacman.d/pacserve

Here's an example for the Xyne repository:

/etc/pacman.conf
...
[xyne-x86_64]
SigLevel = Required
Include  = /etc/pacman.d/pacserve
Server   = http://xyne.archlinux.ca/repos/xyne
...

Alternatively (for official mirrors only), you may insert the Include...-line at the top of the Pacman mirrorlist file or let pacman.conf-insert_pacserve generate a pacman.conf file for you.

Troubleshooting

Problems if using external downloaders in pacman.conf

If you're using an external downloader such as wget, pacsrv may return errors when downloading. To work around these errors, simply quote the url and output formatting strings (%u resp. %o) using single quotes:

XferCommand = /usr/bin/wget --timeout=6 --passive-ftp -c -O '%o' '%u'
