I experienced this problem with Puppy Linux 1.08, resetting, detaching/reattaching made no difference.
In the end I permanently detached that host from this project. |

It's a binary log. I can't even read it, let alone understand it. Can it be exported as text? It's an ethereal log. I've exported the log in xls format, but it's harder to read it : http://jejebr.chez-alice.fr/divers/checksumtxt.xls |

I don't see any problems in the log. Looks like the issue is elsewhere.

Checksum problems are much more visible using the ethereal log, warnings are displayed in yellow, errors in red.

If you look, you should see the packet being resent. That's how the transport layer works.

Someone reported on the net that there are two ways/methods/programs or whatevers ( I do not recall exactly) for computeing checksums and each returns different results. They recommended that if the source was reliable to accept the download. The comment was about downloading a binary OS edition file.
If BOINC or UD uses method one and your system is calling method two than you'll see a check sum error. For What It's Worth, knowledge. Hope this helps Paul T. |

There are many ways to compute checksums! The standard way is to compute a hash. There are a number of hash algorithms. You can rest assured that the BOINC client software and the BOINC server software uses exactly the same hashing algorithm. Off the top of my head, I think they use MD5 (the most common hash algorithm for this sort of thing).
This is a BOINC feature, not an operating system feature. |
