From OSGeo
Jump to navigation Jump to 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.

  • 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).
