When I do an "ssh <aixhost> uname -M" I get a null string back. All
other uname options work. I'm trying to imbed it in a ksh script and
the script is initiated via ssh. The offending line is pretty simple,
echo "`uname -M`\t\c" . But ssh always returns a null. Any ideas?

What AIX version are you running? It works ok on my 5.2 ML6 hosts and
also on 4.3.3 ML11 hosts, too.

I made a test script: /tmp/test.sh with:

#!/bin/ksh

echo "`uname -M`\t\c"

Made it executable, then on my workstation:

$ ssh <host> /tmp/test.sh

Returned output as desired.

One thing you might try is putting in full path to uname: /usr/bin/uname.
