Hi,
No, ftping in binary.
I am running textutils-2.0e6 rpm (the latest) from www.linuxppc.org which supplies
md5sum
I will check what I am running on Solaris.
hmm, I wonder which one is broken?
Thanks,
Kevin

Simple test cases: on both machines do
for string in \
"" \
"a" \
"abc" \
"message digest" \
"abcdefghijklmnopqrstuvwxyz" \
"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789" \
"12345678901234567890123456789012345678901234567890123456789012345678901234567890"
do
echo -n $string | md5sum
done
The results MUST be:
d41d8cd98f00b204e9800998ecf8427e

Hi,
Just to have a bit of fun, how about this (3 different systems)
Each generates a different md5sum but all generate the same cksum!
(and adding -b to md5sum makes no difference)

I guess md5sum is not a very reliable or consistent checksum measure for moving
files between ppc linux, MacOSX, and Solaris 7 Sparc.
Back to the old cksum for me.

Kevin,
Don't know what is going on with your md5sum, but
I ran it on a LinuxPPC 2.2.17 System and a SunOS 5.6,
and got the same results ?????? The version of md5sum
on Linux was 1.22, and the version on Sun was 2.0.

Hi,
Here is what md5sum --version says on my machine.
[kbhend@localhost kbhend]$ md5sum --version
md5sum (GNU textutils) 2.0e

This appears to be newer that yours. I will upgrade textutils again on both
my box and the solaris 7 box. Hopefully eventually they will coincide.
I still don't know why MacOSX differs from both. I thought it would match
one or the other so that I knew which one to upgrade.
Thanks,
Kevin

Hi,
I upgraded my Solaris 7 to the gnu 2.0 version and now it matches ppc linux
completely.
That still leaves MacOSX out in the cold but...
Thanks for the hint.

Hi,
I ran md5sum on a big bz2 archive on my ppc linux box and then
ftp'd it to my Sun Solaris 7 box at work.
I checked it with md5sum on that machine and it differed.
Okay I thought, a bad packet during upload.
So I tried again, same result.
I then passed back and forth (known good archives) and the md5sums
were different.
Okay, I thought maybe an endian issue but both Solaris Sparc and PPC
Linux are big endian.
Should these sums be different?
Thanks,
Kevin

no, that would rather defeat the purpose of md5sum hashes. one of
your md5sum programs is broken.
or perhaps you ftp'd in text mode instead of binary mode.
