.Sh NAME
|
|
.Nm setiathome
|
|
.Nd the SETI@home client program
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Ar options
|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
is the UNIX version of the
|
|
.Tn SETI@home
|
|
client. It downloads radio telescope data from a network server, analyzes
|
|
the data looking for signals of extraterrestrial origin, and uploads results
|
|
to the server, repeating this cycle indefinitely. See
|
|
http://setiahome.ssl.berkeley.edu for more information.
|
|
.Pp
|
|
The first time you run
|
|
.Nm
|
|
it will interactively ask you for email address, name, country etc. This
|
|
info is stored in a file and no interaction is needed when you run the
|
|
program subsequently.
|
|
.Pp
|
|
After this you can run
|
|
.Nm
|
|
in the background, and direct its output to
|
|
.Pa /dev/null
|
|
if you like.
|
|
.Pp
|
|
.Nm
|
|
can be freely aborted and restarted. It saves its state in files,
|
|
and will pick up where it left off.
|
|
.Pp
|
|
.Nm
|
|
requires about 0.5\ MBytes of disk space in it's working directory, and about
|
|
12\ MBytes of memory. If you have ample physical memory, it's work load
|
|
should be almost undetectable.
|
|
.Pp
|
|
This port to FreeBSD includes a start-up script (usually found in
|
|
.Pa /usr/local/etc/rc.d/setiathome.sh )
|
|
that starts
|
|
.Nm
|
|
at system start-up. You can also use this script to set up a working
|
|
directory
|
|
.Pa ( /var/db/setiathome ) ,
|
|
and lets you register with or login to
|
|
.Tn SETI@home
|
|
by calling it with the argument
|
|
.Li register .

|
.Pp
|
|
.Sh FILES
|
|
The program generates several files with
|
|
.Pa .txt
|
|
extension in the directory from which it's run. These should not be
|
|
modified.
|
|
.Pp
|
|
If you want to run multiple instances of setiathome
|
|
(on a multiprocessor machine, or on multiple machines
|
|
that share a filesystem) each one must be run
|
|
in a different directory.
|
|
.Pp
|
|
setiathome uses a lock file
|
|
.Pa ( lock.txt )
|
|
to prevent multiple instances from running in the same directory.
