I'd be happy to email you a copy however
your profile says you have elected not to
receive emails directly. It's a bit too long
to post. Note, that I am not doing a mksysb, I'm
just doing a backup of a file system to tape
using the "backup" command and "tctl" to
manipulate the tape device (plus a few other
things). You can send me mail directly via my
profile and I can send you the script via reply
directly to you.

Regarding your "execute permission" error,
try...

chmod 755 /usr/lpp/CPfw1-41/log/fwtestlog.sh

...I'm assuming you own this file. I'm also
assuming the error is not being generated
from inside the script. It may be that the
script is trying to execute a command for which
you do not have permission but from the error
you mention, I'm assuming it's just the
fwtestlog.sh script itself that is not executable.

On "sendmail", there was nothing to configure.
We have an internal DNS that specifies our
mail server (via MX record entry) so when
I "mail me@mydomain.com", the mail is routed
correctly. Can you send mail from the command
line
