| |
Hello,
When I transfer files to my linux 2.6.1 box their content changes (tested via md5 sums).
I transfered a 1,8 GB (mpeg) file serveral times to this machine by using either pure-ftpd (upload) or wget (download) on that machine. I got a different md5sum each time. Same problem with a 1,4 GB (zip) file, but *not* with a 0,7 GB (mpeg) file.
When I boot the machine with Knoppix 3.2 (Linux 2.4.21-xfs) and upload the 1,8 GB file to it's ftpd (same target harddisk/partition/directory), the file is ok.
When I dupplicate the correctly recieved file with dd or cp under Linux 2.6.1 there is no corruption, too.
I don't know what tools I should use to determine at what positions these corruptions start and how much is corrupted. But I think about the first 1 GB is transfered correctly (diff needs some time before it says "Binary files test-2.6.mpeg and test-2.4.mpeg differ")
Kernel is built without module support.
