There are two steps after you finish a result.

1. BOINC try to upload the result file to the data server
2. BOINC reports the successfully uploaded result to the scheduler

Step 1. happens immediately after the WU is crunched and may fail because of missing internet connection. Then BOINC set a deleay (increasing up to 4 hours) and retry after this deleay time. On windows dialup hosts BOINC asked (if customized) befor connect to the internet, don't know if this works on linux. Have no dialup linux.

Step 2. happens normally when the client ask the scheduler for new work. Because this can be to long to wait for some users, they use the option -return_results_immediately. This means BOINC didn't wait until there is need for new work, it connect the scheduler after each upload. In other case BOINC is collecting the reports about the uploads.

You can force BOINC to connect the scheduler manually with the option: -update prefs [URL] where URL is the projekt URL.

Thanks for your answer, now i understand how Boinc handles resulting data, just one question to make this clear.
There is no way to force sending of data (deleayed step 1) like I can force update of scheduler with -update prefs [URL]?


P.S. I can set linux to connect to internet when Bionic need's it, but I don't want that solution :/

On Window this is build in the GUI. As I remember the CLI client is missing this option at the moment. I agree that it is needed, but think it would be come at first with the new Linux (universal) GUI. I hope that it is finshed this year.

This doesn't do anything.

On a Solaris box doing dial-up PPP:

# ./boinc_3.18_sparc-sun-solaris2.7 -update_prefs http://setiathome.berkeley.edu
2004-07-10 14:54:37 [---] Starting BOINC client version 3.18 for sparc-sun-solaris2.7
2004-07-10 14:54:37 [SETI@home] Project prefs: no separate prefs for home; using your defaults
2004-07-10 14:54:37 [SETI@home] Host ID is 61100
2004-07-10 14:54:37 [---] General prefs: from SETI@home (last modified 2004-07-09 14:03:29)
2004-07-10 14:54:37 [---] General prefs: using separate prefs for home
2004-07-10 14:54:37 [SETI@home] Sending request to scheduler: http://setiboincdata.ssl.berkeley.edu/sah_cgi/cgi
2004-07-10 14:54:46 [SETI@home] Scheduler RPC to http://setiboincdata.ssl.berkeley.edu/sah_cgi/cgi succeeded
2004-07-10 14:54:46 [SETI@home] Project prefs: no separate prefs for home; using your defaults

And at this point the output hangs indefinitely, and there is no network
traffic. So how do I connect to the SETI@home server when I'm actually
connected to the Internet, and not according to some mystery schedule
determined by the BOINC software?

There must be many participants, like me, who will make a dial-up connection
because we have finised work to upload. But BOINC doesn't give us the option:
by the time we notice the work is ready, it is too late. Since we're not
connected, we get:

Can't resolve hostname setiboincdata.ssl.berkeley.edu (host not found)

and then something like:

Backing off 1 hours, 8 minutes, and 35 seconds on transfer of file setiathome_3.08_sparc-sun-solaris2.7

Tough luck for us, I guess, for not being on-line at the correct second!

Disappointed...

There is a way:

1/ shut down BOINC

2/ open client_state.xml in an editor

3/ find these tags: next request time and min_rpc_time

4/ replace the values in both places with 0 ## that's a zero

5/ save the file and restart Boinc with -update_prefs URL

That's it.

It's a little more work but more enjoyable than waiting out a "3 hour, 10
minute, 28 seconds" deferment notice.
