Re: [PLUG] If not SFTP, how's about FTPS?

I would netcat on the server and see if you can telnet to the port from the client.  I his would rule out the firewall.

Compile a newer version is ssh.

Check usual suspects, se Linux, iptables, xinetd/inetd configs. 

Restrict what ports the daemon can use in the config.

use a different method:

This traffic would be from the DMZ to the trusted zone on a non-established connection.

Have you tried running tcpdump/tshark/wireshark?
