From OSGeo
Jump to: navigation, search

The Web Extra VM is a Debian virtual machine administered by SAC, hosted on OSGeo3 at OSU OSL and used for hosting web sites and services that are directly the responsibility of SAC and that don't fit on the other more special purpose VMs (ie. TracSVN, or Drupal). OSGeo member/project services that SAC isn't willing to take direct responsibility for likely belong on either the ProjectsVM or the AdhocVM.

The VM is reachable by ssh at webextra.osgeo.osuosl.org. Anyone in the https://www.osgeo.org/cgi-bin/auth/ldap_shell.py?group=sac (SAC) list has ssh access, and anyone in this group can add new people via the link.

Existing Services on Web Extra VM

Web server

The web server is Apache, with configurations in default places.

SSL certificates

HTTPS is done with a mix of letsencrypt and commercial certificates. Letsencrypt ones are in /etc/letsencrypt, others are in /etc/ssl. As of October 2016, only europe.foss4g.or uses the letsencrypt certificate.

Web sites


  • /osgeo/foss4g/mum2003-web
  • Admined by FrankW
  • static html historial site
  • Backup available in /osgeo/backup/longterm/mum03 on BackupVM.




Status: offline due to massive spamming

TODO: implement moderated queue or other antispam measure

  • /var/www/gallery/
  • content is in sqlite DB
  • Spam removal howto: to be implemented


  • /osgeo/foss4g/uploads
  • Admined by FrankW, jmckenna
  • used for FOSS4G 2011 workshop files (through SFTP)


Includes main www and FOSS4G 2003, 2006, 2007, 2008, 2009, 2010, 2012, 2013

  • 2011 is on webvm - as it's using Drupal
  • Most are static dumps from CMSs that were used,
  • 2008 uses the OCS instance (conference.osgeo.org) hosted on webextra
  • Most being moved from osgeo1 29sep11 by tmitchell
  • 2010 also moved from projects vm:
  • 2013 site lives in svn and is checked out here manually
  • Static archives are being made in September 2014. I am using wget -m -k -E -w 10 http://2010.foss4g.org -o 2010 revised to wget -m -k -K -E -p -w 10 http://2010.foss4g.org -o 2010_2.
    • Preliminary review indicates that this method is working, would like to ask the LOCs and chair of previous conferences if the archive is correct before discarding the running CMSs
    • 2008 doesn't look like it worked fully, will try adding -p to see if that helps.
    • Also mirroring http://foss4g-e.org/ which will then be served off of europe.foss4g.org, not sure what needs to be done to make that work, trying the same thing.
    • Once done, need to do backups
  • Backups should be put /mirror/longterm on backup.osgeo.org as a comperessed tar file per the instructions there (maybe here?, SAC:Backups).

  • Serves as http://vmap0.tiles.osgeo.org/wms/vmap0?SERVICE=WMS&VERSION=1.1.0&REQUEST=GetCapabilities
  • Lives in /var/www/tiles/vmap0 and /mapdata (2.3G)
  • Originally setup by Chris Schmidt.
  • Currently produces the bulk of load on the webextra VM.
  • Presumably this is widely used as a default layer in OpenLayers.
  • For the purpose of sharing the load, a copy of this service has been set up on "sphere.telascience.org" and a round-robin DNS provides balancing (Martin Spott).
