Very soon I will have access to 60 P4 3.4Ghz and they will be sitting around all day doing nothing. The problem is they do not and will NEVER have internet access. I have access both at home and my office and using my jumpdrive I can transfer results back and forth. Is this something that can be done and, if so, how do I do it???????

Thanks for everyones help,
Mike

There is a 50 WU download limit per day.

So even if you could gather the units to distribute to these machines you could only feed 2 or 3 of them with 50 WU.

There is a mechanism being worked on in the Alpha boinc version to have a "proxy" machine which will gather WUs and distribute them to a pool of internal machines, however, I believe the internal machines need to be able to connect via ethernet to the "proxy" machine.

The computer that processes the wu has to connect to the ulr.
The download wu is assign to that computer, if it is process on another computer you will not get credit.
The bottom line is ever computer has to be connect [some way] to the net to download, process and then upload the results.

Really?

Ok.. what you need is..
one of the following:

Bluetooth cell phone with data access.
use a bluetooth usb dongle to connect to the net thru the phone, all other pc's use that workstation as a proxy.

802.11 Wifi Connection nearby. Similar tactic to bluetooth, except you connect thru a nearby wifi access point.

or..
Satellite dish?

The limit is per host, not per account... a single machine has to eat up 50 workunits; 60 machines could go through 3,000 workunits in a day before hitting the limit.

A single machine would be downloading the WUs. You have to gather them before you can distribute them on a floppy or whatever to the 50 machines that can't connect to the Net.

Yeah, but you'd want that single machine doing the downloading to not be downloading all the workunits for a single host.

Sixty computers... surely you could drop a modem in one, set it up with squid to cache common downloads like the application itself, and share out over the network connection to the sixty machines?

Sixty machines, ten workunits each, three-hundred kilobytes per workunit... that would come out to about 180MB. Hmmm... that's a bummer. :-)

YES ABSOLUTELY TRUE!
That is why a "proxy" is being alpha tested.

OK, this is what you should do (it works, I've done it), assuming you run Windows:

You need a USB-thumbdrive to transport the WU's to the PC's without internet access!

1: Install BOINC on your PC with internet access. DO NOT ATTACH to a project at this point!
2: Exit BOINC
3: Copy C:\\program files\\BOINC to the thumbdrive
4: Run boinc_gui.exe FROM the thumbdrive
5: Attach to any project you like, you will be assigned a unique host ID
6: Download WU’s
7: Exit BOINC
8: MOVE (not copy) thumbdrive:\\BOINC to a PC without internet access
9: Use whatever you like to start BOINC (either as service or using the GUI). Location of the BOINC dir is not important. No need to run the installation file!
10: repeat steps 3 through 9 for every PC, you will be assigned a unique host ID at step 5 every time.

Now for the flushing of the WU’s:
11: Exit BOINC on the PC without internet access
12: MOVE PC:\\BOINC to the thumbdrive
13: Run boinc_gui.exe FROM the thumbdrive on your PC with internet access
14: flush and download WU’s
15: steps 7 through 9 from above
16: repeat 11 through 15 for every PC

Yes, the last post would work. But I would be doing a awfull lot of work myself. If boinc becomes proxy capable then I could do this method on the proxy machine and it would be much easier. If I were a real guru, I would write a program that would do it for me. I'll just keep waiting for the proxy:)

Saddly enough, there is no possibility of internet access.

Thanks for all the suggestions!

If a proxy is possible, you can already use most of the general purpose proxies available.
