lin-seti is a command line program allowing the user to mantain a cache of work units for the Seti@Home client. It should run without any problem on Unix-like systems, including Linux. It is designed to be fully compatible with SETI Driver (similar software for Windows), so you can share the same cache on dual boot systems.
gnome seti_applet displays the status of any running seti@home process. It shows the best spike, best gaussian, number of units completed, percentage complete of the current unit, and the total CPU time used thus far. Seti client can be started and stopped from the applet menus, and can be configured to auto-start on panel startup.
SETI@home is a scientific experiment that will harness the power of hundreds of thousands of Internet-connected computers in the Search for Extra-Terrestrial Intelligence (SETI). The client (currently available for most UNIX machines) downloads and analyzes radio telescope data. There's a small but captivating possibility that your computer will detect the faint murmur of a civilization beyond Earth.
setirotate automatically spawns the SETI@Home commandline client, rotating it through work units in a work unit cache. You can configure the number of work units to store, the number of processes to run simultaneously, the number of simultaneous result-upload/workunit-download transfers, the time interval within which its allowed to perform said transfers, and the timeout interval for when a transfer fails. It will immediately start working on a work unit when the previous one finishes, while uploading the newly finished result (if the upload interval permits) in parallel. It strives to always keep something running.
