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.
You can either install pacserve manually from the AUR, or with the following method:
from Xyne's repository
add this to your /etc/pacman.conf, replace (x86_64 with i686 or any if necessary):
[xyne-x86_64] # A repo for Xyne's own projects: http://xyne.archlinux.ca/projects/ SigLevel = Required Server = http://xyne.archlinux.ca/repos/xyne
now install pacserve:
# pacman -Sy pacserve
and enable / start the daemon:
# systemctl enable pacserve.service # systemctl start pacserve.service
in case you use iptables, you will probably want this service: pacserve-ports
Instead of pacman, use the pacsrv wrapper to perform an update/install packages etc. 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
Problems if using external downloaders in pacman.conf
If you're using an external downloader sch as wget, pacsrv may give errors when downloading. To work around these errors, simply enclose the url and the output in inverted commas.
