Subject: 2.6.1: data corrupton when recieving files > 1GB over network
Date: Sun, 11 Jan 2004 17:36:32 +0100 [thread overview]
Message-ID: <5.1.0.14.2.20040111161640.014ad6c0@localhost> (raw)
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.
