HELLO,
I may have make some progress. I can SSL/TLS on a local machine but it does not work on a remote. I get (filezilla): Disconnected from server Status: Resolving address of homere Status: Connecting to 193.49.194.196:21... Status: Connection attempt failed with "EHOSTUNREACH - No route to host". Error: Could not connect to server Status: Waiting to retry... Status: Resolving address of homere Status: Connecting to 193.49.194.196:21... Status: Connection attempt failed with "EHOSTUNREACH - No route to host". Error: Could not connect to server
ssh works fine. However, I have a possible explaination. This machine is behind a firewall and to be able to make ssh, I add to ask to have the ssh port open. Probably, the ftp port is closed. Should I ask to have it open to use ssl/tls? Is it port 21? or 990? how can I check the port 22 is open while the other ones are closed on the firewall (I do not have admin access to this machine).
Thank.

Maybe you could use "tcpdump" in order to see which ports are used while making a connection on the local machine. That may show which ports need to be opened on the firewall.

Patrick,
Do you have a compelling reason to use FTPS. If not, SFTP provides the same functionality (encrypted file transfers) and it runs over SSH, so it should *just work* in your environment.
