Software mirror sites

Official master site via HTTP/FTP

Cascaded mirroring:
Tier-1 mirrors: These mirrors read daily from the master site and also act as rsync servers.
Tier-2 mirrors: These mirrors read from the tier-1 mirrors (these sites may be 1-2 day(s) behind the master site)

Become a GRASS mirror site!

Help support your favorite Free Software GIS and become a mirror. Due to the high network traffic on our main site sometimes resulting in timed-out connections we encourage you to mirror this site.

Requirements: A GRASS mirror site requires around 690 MB space, the space requirements may vary due to the changing presence of precompiled binaries. Also PHP (PHP3 or later) support is required.
If you would like to support the GRASS community, do not hesitate to contact us and report the running mirror.

How to set up a mirror site:
The master site at OSGEO (grass.osgeo.org) supports the "rsync" software protocol to synchronize the mirrors automatically overnight. The idea of using "rsync" mirror software is that only changed files are downloaded which minimizes the network traffic. The master site provides "rsync" access only to a few "tier 1" mirrors; you can then connect your mirror site to these "tier 1" mirrors (as they also provide "rsync" capabilities).

Mirror site setup in greater detail:

  1. Install the rsync software.
  2. Check if you can connect - note the two '::' characters (this command should display a welcome message):
    • rsync grass.osgeo.org:: (master site)
    • rsync mirror.quintex.com::grass (tier 1 mirror, provides "rsync" for other mirrors)
  3. Define a daily cron-job (in 'crontab') for rsync (example):
    /usr/bin/rsync -r --delete --times --links --bwlimit=200 grass.osgeo.org::grass /mirror/grass/
    This will copy/update the GRASS site to your local directory /mirror/grass/
  4. Check if the synchronization works the next day(s).
  5. Announce the new mirror site for this mirror list to us.
If you are interested to serve as tier-1 mirror (most welcome!), please let us know.
