Server To Server FTP

[zahumi]

So ... I've designed a site that allows the uploading of photos to our server on AWS ... What I'm trying to do is, after the photos have been uploaded, shoot them off to another server within our domain but keep getting a connection error. Funny thing is that when I try to access from my local machine I have no issues connecting.

Ex:
- upload photos to site1.servername.com
- I'd like to move them via ftp to another site on the network site2.servername.com

Error message I get from "site1" when trying to FTP to "site2" is
- A connection with the server could not be established

Any ideas?

What are you trying to use as FTP client (for initiating the transfers)? FileZilla Client doesn't support server-to-server transfers.

Please note that server-to-server transfers do not work with FTP over TLS. You can only use plain, non-encrypted FTP, which is a risk.

You need properly configured FTP servers, one of them needs to work in Active (PORT) mode and the other in Passive (PASV).

A, yes, although it should be obvious: Both servers must be FTP, FTP to SFTP or vice versa is incompatible, as are the two protocols.

Great! I'll give it a shot! I'm actually using Smart FTP client.....

On the same train of thought - what if I am on "Server1" and want to FTP over to "Server2" ... would there be anything special I would need to do to get that working?

Doesn't matter where you are, you always need to connect to both servers first, to start the transfers. Required configuration is always the same.

Note that by "server" as in "server to server" transfers, we mean FTP server software. So, even if "Server1" is a Server OS, directly FTPing to "Server2" using an FTP client still makes you a client. That's not a server-to-server transfer at all.
