I can't seem to get rid of the destination filename prompt. All it means is that I have to have another line in the script which restates the filename, but at least the password prompt is now gone. I'll have to load it into config change templates and see if it works there also.
I agree that FTP is faster, but when it comes to dealing with 3000+ entry inbound ACLs, the advantage of being able to use SCP over port 22 is well worth the extra transfer time. If you've got SHH, you've got a file sent every time on the first attempt. I also found that SCP bandwidth rates are much more stable than FTP when multiple sockets are opened. I'm not sure if that cost benefit is greater than the higher speed of FTP, but it closes the gap at least.
You're lucky you get to use FileZilla. We've been using PuttySCP and are trying to use SolarWinds SCP now that NCM is up and running for us.
Thanks for the reply!
