This document outlines one way to share Arch Linux packages across a LAN. A better way to do this would be to create a Custom local repository with ABS and gensync and make the repository available across the LAN using NFS or FTP. This document should be edited to describe this process in detail. For the time being, the original HOWTO is left intact below:

To share all your downloaded packages in your lan Pros save bandwidth, diskspace and time. "pacman -Sy" will sync against our local repository "pacman -S pkgname" try to download and install pkg from localserver if pkg not exist it download from the next server in the list /etc/pacman.conf and save pkg on localserver. "alsync" will update localserver db against ftp.archlinux.org

ex. for my network serverip=192.168.14.3 network=192.168.14.0/255.255.255.0 adjust to yours


on the server side

on your server create an nfs share readwrite for all pc on your lan

If you run Arch Linux on the server you can

 pacman -S rpcbind
 pacman -S nfs-utils

edit /etc/exports add line

/var/cache/pacman/pkg 192.168.14.0/255.255.255.0(rw,no_root_squash,sync)

add rpcbind, nfs-common and nfs-server to DAEMONS in /etc/rc.conf

run the followings:

 # /etc/rc.d/rpcbind start
 # /etc/rc.d/nfs-common start
 # /etc/rc.d/nfs-server start

check the nfsshare run "exportfs" on server.

on all clients

  • rename /var/cache/pacman/pkg to /var/cache/pacman/pkgorg
  • create a new /var/cache/pacman/pkg and mount the nfs share there
  • run "mount -o rw,nolock 192.168.14.3:/var/cache/pacman/pkg /var/cache/pacman/pkg"
  • if the mount from command line does not work add this option "nfsvers=3"

or if you want it automount after the reboot, add this line in /etc/fstab

 192.168.14.3:/var/cache/pacman/pkg /var/cache/pacman/pkg    nfs    rw,nolock
  • again if the mount does not work, try to add mount option nfsvers=3 to the fstab entry.
  • run "mount -a"
  • run "df" to check mount
  • move all your already fetched pkg from your clients
 /var/cache/pacman/pkgorg to /var/cache/pacman/pkg
  • edit /etc/pacman.conf and add this lines directly after the line
 {current}
 Server = file:///var/cache/pacman/pkg

and after

 {extra}
 Server = file:///var/cache/pacman/pkg

I have skipped the step 3 because for me it works as i want already. I sync from each PC and all share the pacman cache.

To sync your local repository v.s. archlinux.org

  • "alsync" connects, login, and update your packages database on the local nfsserver
 pacman -S openssl
 pacman -S wget


  • create a file called /bin/alsync and put in this lines
 cd /var/cache/pacman/pkg
 wget -N ftp://ftp.archlinux.org/current/.db.
 wget -N ftp://ftp.archlinux.org/extra/.db.
  • chmod 777 /bin/alsync

copy this file to your clients

  • to try run as root on first client
 alsync
 pacman -Sy
 pacman -S new-pkgname
  • move to next client and run
 pacman -Sy
 pacman -S new-pkgname
