I just downloaded KNOPPIX_V4.0.2CD-2005-09-23-DE.iso via Bittorrent (Azureus). Azureus said it is ok, but already the file sizes don't fit. I have saved 711.12 MB while the file was listed with 694.61 MB. The MD5 file signature could be verified. The MD5 itself NOT!! I calculated with 2 independent tools "01 4f b2 d8 d6 6f 0f 57 e5 ed 44 9b a3 7e ee c8" but the control value is "0f67423e0d784f18db07409fd1b185a1". Any idea what can have gone wrong here?

The funny thing is, Azreus still uses this file to upload data for others.
