Thanks for the info! Hum... Now I'm really confused. It seems there's one acronym for two protocols: Does SFTP stand for "
SSH File Transfer Protocol" or "
Simple File Transfer Protocol?... Apparently, both! :-)
Based upon what I'm reading, Wikipedia indicates that the Simple File Transfer Protocol uses port 115, which matches up with the port number I was provided by our vendor. SSH File Transfer Protocol seems to function inside of an already established SSH connection, through port 22--closely matching what northlandboy mentioned.
Now, I see that there is also an FTPS (a.k.a. FTP Secure), which operates in conjunction with SSL. After establishing the initial connection on port 21, I'd assume FTPS would then switch to port 443 for the encrypted portion of the session (?)...
Quote:
The client connects to the server port 21 and starts an unencrypted FTP session as normal, but requests that TLS security be used and performs the appropriate handshake before sending any sensitive data.

According to the article provided by kva.kva, it appears that, in order to use SCP, an SSH connection would also first need to be established. Therefore, in response to my number two question, the vendor would need to configure their server to accommodated SSH prior switching from Simple FTP on port 115 (not SSH FTP) to SCP. Correct?
