Hi,

When I tried to get CSUM for a file which i transferred from Linux (RHEL) to my AIX box i got the following error.
csum: <file_name> does not exist.
csum: unable to access one or more files.

The command i use to get the checksum is

CSUM <file_name>

Am i missing anything here? This works fine for smaller files.

I was able to get the checksum for the same file in Linux box.

Also i am getting this error only for larger files.

Any suggesstion would be greatly helpful.

Thanks
Guna

Guna,

AIX 6.1 has a 2G limit on the csum command because a 64 bit version of the library that csum
uses for cryptographic functions is not available. Not sure when/if that limitation will be removed.

You can use the perl script below to get the md5 digest on files over 2G in AIX. It can be found here:

http://www.ibm.com/developerworks/aix/library/au-satsystemvalidity/index.html

It takes a filename as an argument, e.g., md5sum.pl <filename>

use Digest::MD5;
use IO::File;

my $chk = Digest::MD5->new();

foreach my $file (@ARGV)
{
$chk->addfile(IO::File->new($file));

print "$file -> ",$chk->hexdigest,"\n";
}
