What are you running manually?

Do you have the output from hexdump -C that I asked for?

I ran the script with little modifications and it is working fin now...

thanks for all your helpSmilie Corona688

What is the difference from this line
Code:
ssh $host exec /bin/sh -s $HOSTNAME 2>&1

to this line?
Code:
ssh $host exec /bin/sh -s $HOSTNAME 2>/dev/null

One of them sends standard error into /dev/null, which basically gets rid of them. I'd been trying to keep those lines -- the "echo stuff >&2" in the <<EOF block -- and send them into your logfile, but if that was the line that fixed it, they must have been ending up in the gzip instead. Sigh. Smilie

How can I send the input of the remote server into my logfile. No output was sent to the gzip files, since the html files look ok.

The way it was originally? ssh $host exec /bin/sh -s $HOSTNAME 2>&1 ?
