Depending on the data you are transferring, Rsync (http://rsync.samba.org) over SSH may be better than SCP or FTP. SCP and FTP don't work well for updating data frequently as each transfer will exchange all data -- changed or not. Rsync will only transfer changed data. For large files, it will only transfer the portion(s) of the file that have changed. Since it can run over SSH, it has the added security value that makes SCP more attractive than FTP. I've found rsync to be a big win when I'm working with a client who is insistent that they need to share filesystems for "timely update of data." One client is updating 2+GB of data in less than 5 minutes using rsync over SSH (yes, most of the data is unchanging -- but the location of the changes is always different). Rsync also runs on Win32 (with the cygwin library). It's free, ships with RedHat, and is built for most of the interesting OS's. No, I'm not a salesman... :) Todd --------

There are free versions available for download, so it's hard to beat the price. See www.openssh.org for details. mjr. --- Marcus J. Ranum Chief Technology Officer, NFR Security, Inc.
