Intern:Usero

The directory usero is the long-term archive of the hierachical storage system (hs) operated by the computer center of the AWI. Access via ftp at Any data files stored in the directory structure below hs/usero/... must be described and referenced in Pangaea. Files are stored on tape and are loaded on request through a link in Pangaea; loading time is less than a minute and indicated by a rotating wheel. Login protection of files is possible by adding an empty marker file named .datasetxxxxxx with xxxxxx=ID of the data set to the same folder.
 * hssrv1.awi.de/hs/usero/... (with internal login only)

All files in usero (excluding „lost+found“ and „tmp“) can be linked through its path and thus are accessible from the Web, e.g. Special files like http://hs.pangaea.de/favicon.ico and http://hs.pangaea.de/robots.txt are important to avoid googlebot trafic on hs and are stored external from hs, NOT on tape.

Important: Although the web server is also available via HTTPS, please create links in datasets using HTTP only. This lowers CPU usage on both client and server while downloading huge files. If the files require a login/password, the user is automatically upgraded to HTTPS for login and download. Therefore it is recommended to make datasets with files on Usero freely accessible.
