As Ralph indicated, he'll add the hostname to the error message (but that might be tricky; that error message is coming from rsh/ssh...).

In the meantime, you might try (csh style):

foreach host (`cat list`)
echo $host
ls -l /opt/SUNWhpc/HPC8.2.1c/sun/bin/orted
end

that's what the tentakel line was refering to, or ...
