can't use FileZilla with pure-ftpd in TLS/SSL mode

[peter_daum]

There has been a bug report (#1015355) with the same
subject
which unfortunatley has been deleted without any comments.

My experiences have been the same: the connection is
established,
but somehow filezilla can't get a directory listing.

Is there any way to connect with filezilla to a
pure-ftp server
over a tls secured connection?

Same problem to me.

I used FileZilla Server and connected with FileZilla via
implicit SSL/TLS (Port 990). Everytime i got:

Status: Verbinden mit 83.129.73.139:990...
Status: Verbunden mit 83.129.73.139:990, SSL-Verbindung wird
ausgehandelt...
Status: SSL-Verbindung hergestellt. Warten auf
Willkommens-Meldung...
Fehler: Timeout entdeckt!
Fehler: Verbindung kann nicht hergestellt werden!

on the serverside i got:

(000054) 22.03.2005 00:43:00 - (not logged in)
(83.129.73.139)> Connected, sending welcome message...
(000054) 22.03.2005 00:43:00 - (not logged in)
(83.129.73.139)> 220 FileZilla Server version 0.9.6 beta
(000054) 22.03.2005 00:43:00 - (not logged in)
(83.129.73.139)> SSL connection established
(000054) 22.03.2005 00:43:31 - (not logged in)
(83.129.73.139)> disconnected.

Then i tried to connect with another FTP-Client to my
FileZilla Server and it works...

1) Verify that the destination IP address is correct.
2) Increase the connection timeout threshold under Global

3) Switch to the opposite data connection type (PASV or

4) Verify that the problem is not local by trying to

connect to an alternate server.

5) If a server name was used, verify it resolves to the

correct address.

6) If using a local server table for server name

resolution, check to see that it doesn't resolve to an

7) Try pinging the address.
8) If you are using a router, verify the router is up and

running (check by pinging it and then ping an address
outside of the router).

9) Do a traceroute to the destination to verify all

routers along the connection path are operational.

10) Verify that your subnet mask is setup properly.
11) Verify that your local software or hardware firewall

is not blocking outbound connections originating from CuteFTP.

12) Verify that your anti-virus software is not at fault

(try disabling it).

addition:

can it be that the client waits for the server to send it's
welcome-msg after the SSL-handshake? I think it must do this
immediately after successfully connected and before
establishing the SSL-Link.

Not sure...

The original bug report was referring to FileZilla vs. PureFTPD:
PureFTPD can not encrypt the data connections, while FileZilla
could only encrypted all or nothing. ( See also:[ 1144783 ]
Error sending PROT P command in Explicit TLS/SSL connections)
This has been fixed in FileZilla 2.2.12
(You should file a new report for your issue)
