    Hi All,

    I've been fighting with TLS and ProFTP for a while now. It seems to work for a while and then go into a tizzy where it stops allowing people to log in and just times out while attempting to get a directory listing. I'm the only person in the machine so whatever changes causes this to happen aren't done by a person as far as I can tell.

    Here's an output of Filezilla attempting to connect:

    Status:	Connecting to xx.xx.xx.xx:21...
    Status:	Connection established, waiting for welcome message...
    Response:	220 ProFTPD 1.3.0a Server (ProFTPD Default Installation) [xx.xx.xx.xx]

    Response:	257 "/home/www/web20" is current directory.

    Response:	200 Type set to I
    Command:	PASV
    Response:	227 Entering Passive Mode (xx,xx,xx,xx,218,178).
    Command:	LIST
    Error:	Connection timed out
    Error:	Failed to retrieve directory listing
    I am using the FTPES (Explicit) setting in Filezilla on port 21 but the FTPS (Implicit) does not work either.

    I have tried both active and passive mode with the same results.

    I have tried connecting directly to the IP rather than the hostname to eliminate DNS time outs with the same results.

    I have tried connecting with the firewall running and with it off. When off, I can usually get a little farther in that I sometimes get a directory listing before it times out, but it still times out.

    I have added a range of passive ports to the firewall and it hasn't helped.

    I cannot find any useful information in the /var/log/messages file (or any other log file that I know of).

    So, I am at a loss on how to figure this out now. Any ideas how to troubleshoot this?

    Did you try also to deactivate the complete firewall?

    Hi Till,

    Yes, I tried it with both the firewall running and completely turned off. When turned off, I seem to be able to get farther, but it still times out on the directory listings.

    Is the server behind a router? If so, does the router forward all necessary ports?

    Things are working now. Turns out that I forgot about a bug with TLS in Filezilla 3.1 in that it has problems connecting using TLS.

    So....use another FTP client and all works...
