FTP Relay or Proxy Server?
Posted on 2009-02-11
We want to migrate in real time to a new FTP server (with a different IP address) from an old one. This is always difficult because there are thousands of users and their DNS doesn't refresh properly. If we shut down the server, there are complaints of unavailability.
What we want is an FTP server that acts as a relay to another FTP server. Kind of like a proxy server. If a user connects to this "relay" server, then it is in fact just passing all the details- Username, password, etc, to the new server and retrieves it for the user.
I don't think that what are currently known as "FTP proxy servers" (as they are commonly thought of) are what we need. I think those are just to relay connections over a corporate firewall.
Or am I mistaken?
How can I solve this issue? Are there any similar products available? The particular server in question is Windows-based.
