Re: Alternatives to sftp?

[Thorne <thorne () beol net>]

Well another way to do it is. SCP or Rsync over SSH. I personaly use Rsync of 
SSH for my backup's at my office. Scp is nice if its a single file you can 
use keys if you need to automate it . I can sustained 4000K a sec across my 
lan with SCP, For a 10mb file it would not be that big of a issue speed wise 
i would think 3 seoncds ?
