id summary reporter owner description type status priority component resolution keywords cc component_version os os_version 10612 Fails to connect (retrieve directory listing) if Firewall is set above Minimum. Nikolai Petrovich Krakpotzky " This has also happened on earlier versions. Filezilla gives the message ""Failed to retrieve directory listing"" during connect. I can get around this by accessing my Cable Modem's Administrator function and changing my Firewall setting to ""Minimum"". I have to keep it at this level during the entire FileZilla session, through and including Disconnect. Naturally, I do not appreciate having to leave myself vulnerable, even for a relatively short window. I'd prefer to keep the higher level set at all times. The log, in its entirety, [minus the particulars of my site] reads: {{{ Status: Resolving address of [XXXXXXXXXX.XXX] Status: Connecting to [YY.YY.YY.YY]:21... Status: Connection established, waiting for welcome message... Status: Initializing TLS... Status: Verifying certificate... Status: TLS connection established. Status: Connected Status: Retrieving directory listing... Command: PWD Response: 257 ""/"" is your current location Command: TYPE I Response: 200 TYPE is now 8-bit binary Command: PASV Response: 227 Entering Passive Mode ([YY,YY,YY,YY],197,52) Command: MLSD Error: Connection timed out after 20 seconds of inactivity Error: Failed to retrieve directory listing Status: Disconnected from server }}} ... and it repeats once, except the second time, one line is different: {{{ Command: PASV Response: 227 Entering Passive Mode ([YY,YY,YY,YY],197,46) }}} This is the only web-site to which I connect. I do not know if this is a function of FileZilla in general, of my site in particular, or of my Site Manager configuration. As to the latter, I do not have a Port specified. I don't know if the "":21..."" refers to the default port, or what the "",197,52"" or ""197,46"" means. I would like to know if: (a) Specifying a particular Port number will clear up this problem. (And, if so, what port number?) (b) This is a ""Bug"" or a Feature"", and (c) If the former, can it be fixed? Thank you."
