I all ! User from many years of seti & boinc, i have recently got an acess to a powerfull set of computers. These Pc can't be connected to internet for security issues. I'd like to run boinc on it, and use an usb disk to transfer the units between a pc on internet and this set of cpus. Can you help me ? many thanks ! ID: 238224 ·  |

Not really possible any more for most of the projects. Has to do something with security issues on the science side and cheating. Don't ask me for details, I simply don't know. But CPDN allows this behaviour, and as it's WUs are really huge, it should be of no problem with the work-cache. Go over to their fora to have a peek for detailed instructions: phpBB Forum BOINC Forum (I didn't do a search, so no detailed link) ID: 238234 · |

But you can setup a internal network between all your computers and install at the one system (with internet access) a proxy server with a firewall. This single system should be have now acces two both networks. The boinc clients in you internal network send there requests for the seti servers to (over) the proxy server, and the proxy server forwards the requests to the seti servers. For security, you can now setup a firewall on the single system, which only allows connects from you internal network to the proxy server. Additional you can install a firewall on each system in your internal network which only allows outgoing requests on the port of the proxy server. ID: 238241 · |

Thanks a lot. I want to notice you that the two different networks couldn't be connected at any point. A firewall is not secure enough for our application. The two networks can't be electricaly (?) connected at all. I already though about CPDN with Huge units. But computers wich will crunch can't be on internet at any time. Even if i ask another one to download the WU's, how can i ensure that the WU will be huge enough for the one wich is not connected ? One year of crunch on a PIII 800 will resists two days on my intranet systems ! SO ? ID: 238728 · |

If you cannot have the hosts connected to the internet, then I'm afraid that they cannot crunch data at this time. Every system must be accounted for, otherwise if they allow this, cheating will become rampant (allow one, allow all). If they cannot be connected to the internet for security reasons, I would think that high security is a priority there, which in turn leads me to believe that they probably shouldn't be running SETI then either, unless the owner agrees to them running SETI, in which case they have to connect to the internet individually.

Hi, all! Is it possible to download using a PC connected to Internet, copy all the files and directories on another PC, let this one to do the job and then, when all the WUs have been crunched, to copy on the first PC and upload the results? And the first PC downloads other WUs to work on? I mean, is it possible to work on a PC on which BOINC is not installed but simply copied from another installation? Thank you! Paolo ID: 241470 · |

No. Please look at the postings from OzzFan and Saenger in this thread. ID: 241608 · |

Hi all! I am occasionally on the forum, so I respond here now! What I asked on February, I do on a regular basis now for several months! I have installed BOINC on my home and work PCs, which have connection, and on my notebook, which has not; then, I have copied this installation directory on an USB pen-drive and let the notebook work! When I need a new WU, I plug the pen-drive at my work PC, stop the installed BOINC and run the BOINC from pen-drive and upload and download WUs! Sometimes there can be a misalignment for which PC have to be granted the credit, but the program runs good and usually credit is assigned! Thank you, again! Paolo ID: 492228 · |

Hi all! Congrats. You have found the known method for allowing work on non-internet connected PCs. Be warned, this method is not condoned or authorized by SETI@Home, which is why we don't tell people about it, and at any point in the future, new features in the software may render this method unusable. For all intents and purposes, it's best to simply follow the SETI@Home recommendations on requiring each PC to be connected to the internet. ID: 492552 · |
