 Checksums question. When I download fix packs, there are also corresponding checksum files (e.g., FP7_MI00086.cksum) that I download. But I do not know how to use them. I tried md5sum, but it gives checksum that does not match: $ cat FP7_MI00086.cksum /ps/products/db2/fixes/english-us/db2linuxIA32v8/fixpak/FP7_MI00086/FP7_MI00086.tar cksum:2567030317 md5:ee21d401b9ba27eb57df6f3cc8e767ca $ md5sum FP7_MI00086.tar ec1e7d5fafd090d3e2c31ee9e5a456d9 FP7_MI00086.tar What is the proper way for me to verify the checksum? I have tried the extreme method of untarring the file and installing it. The results seem to work. -- .~.

I am surprised that whatever IBM uses to get the md5 checksum gives different results from the md5sum program. > > Cheers, > > "Jean-David Beyer" <jdbeyer@exit109.com> wrote in message > news:10lqrgi9qehenc4@corp.supernews.com... > >>When I download fix packs, there are also corresponding checksum files >>(e.g., FP7_MI00086.cksum) that I download.
