Can you try this please, to confirm that the ssh port is open on the
target machine:

nmap -A pamneil.com

Should take up to a couple of minutes to provide a listing of open
ports, among which should be port 22.

Further to my last email -

I have contacted my ISP. They tell me that SSH would use port 3784. Further they say that SSH is not normally enabled for security reasons. If anyone wants it set up they charge £13 a year.

That's not unnexpected, but is understandable - using ssh, it's possible to do all sorts of bandwidth hungry stuff on your site - or CPU hungry stuff (well, slightly easier than doing it via a web interface to PHP)

And I have to say, I discourage it on my customer facing servers, but don't prevent it.

I have emailed back to say what I want to do with it. Awaiting their answer.

I'm sure their answer will be: Cross our palms with £13 (+VAT?) and we'll enable it for you...

Meanwhile, plan B would be to encrypt any files first before transferring them. That would be a pain!!

Possibly. The shell and pgp is your friend... Shouldn't be hard to knock up a script to encrypt a whole directory/heirarchy if needed.
