Description Michael DeGon 2006-09-27 21:16:12 UTC

Description of problem:
Running the the ftp test  downloading ISO from ftp mirrors. Comparing the
SHA1SUM file to the md5sum output of the downloaded ISO with an invalid result.
The byte size  matches between source and target files, but the checksum does not. 

Version-Release number of selected component (if applicable):
FC6T3

How reproducible:
  

Steps to Reproduce:
1.Use command ftp client to download an ISO image from any of the Fedora mirror
servers.
2.Also download the present SHA1SUM file.
3.Compare md5sum output with the SHA1SUM file.

  
Actual results:
ISO file byte target and source size matches, but the md5sum output and SHA1SUM
do not. 

Expected results:
the md5sum output and stated md5sum SHA1SUM file entry match.

Additional info:
This problem has been found on 5 intel PC models with different network card
chipsets. This looks like at FC6T3 specific problem. They are:

Hi,

Did you compare md5sum output to a corresponding item in file SHA1SUM?
md5sum checksums do not match sha1sum checksums.
You should compare sha1sum output, not md5sum output, to a corresponding item in
file SHA1SUM.

Ah! 

I achieved my goal of learnig something new today!! 

You are right, the md5sum is different than the SHA1SUM. 

Please forgive my phoepa!

De nada. Glad to be able to help.
