6 This hint provides details about how to install the SETI@Home client
11 1. Background on SETI @ Home
13 SETI stands for Search for Extraterrestrial Intelligence.
14 It's an organization that analyses cosmic waves, scanned
15 by giant radio telescopes. They are hoping to find a message
16 from another world, one day.
18 Unfortunatly, the amount of data is so huge, that it simply
19 can't be processed by a couple of computers.
20 They need our help. You can download a client program that
21 connects to a server and retrieves a small packet of data (work unit).
22 Then, your computer starts processing the data as a background process
23 (7-10 hours needed) and sends back the results.
26 2. The SETI @ Home client
28 The program is written in such a way, that it only uses
29 the 'idle' processor time, that is when no processing is performed
30 on your machine. Also, it only needs an internet connection to send
31 and receive the work units. It is possible to run clients on
32 multiple machine using the same account. When stopping the client
33 during processing, it automatically resumes the next time you start it.
35 You can grab the command-line linux version of the SETI @ Home client at:
37 http://setiathome.ssl.berkeley.edu/download.html
39 Note that there are different versions for each platform.
40 I use the i686-pc-linux-gnu-gnulibc2.1 which is optimized for Pentium II/III.
42 After the download, untar it:
43 $ tar xvf setiathome-3.03.i686-pc-linux-gnu-gnulibc2.1.tar
45 and move it to the desired directory:
46 $ mv setiathome-3.03.i686-pc-linux-gnu-gnulibc2.1/* /usr/local/bin
48 Start the client for the first time:
51 Fill in the correct information and if all goes well, you should see
52 that the program retrieves 340kb data from the server and starts processing it.
56 Q: I get an Illegal instruction error, and the client bails out.
57 A: You probably downloaded the wrong version for your machine,
58 try the i386 optimized version.
60 Q: The client doesn't seem to connect to the server.
61 A: You're probably behind a proxy/firewall.
62 Try 'setiathome -proxy my.proxy:port'
63 e.g. 'setiathome -proxy 192.168.1.1:8080'
65 Q: It's still not connecting!
66 A: Maybe the SETI @ Home data server went down. Try again tomorrow.
68 Try to keep that client running.
72 You can keep track of your personal statistics to see what rank you have.

75 People are free to create teams, which can compete to eachother.
76 There are a lot of communities out there that created their own team
77 (Team Slashdot, Microsoft Foundation, Team FreeBSD and of course... Team LFS).
79 When you have completed more than 1 work unit, make sure that you join
82 http://setiathome.ssl.berkeley.edu/cgi-bin/cgi?cmd=team_lookup&name=Team+LFS
84 and click the 'Join' link. Follow instructions from there.
