Test targets:
I have used log files at debug level 2, WinSCP 4.2.7 build 758.

I have tested two Win7 machines, one Vista and one XP.

Problem:
When using FTP from one Win7 machine the log reveals that reply "150 connecting to port xxxxx" is missing. Then WinSCP sends LIST -a and the log lists part or whole directory, but ends with "Disconnected from server" and "Could not retrieve directory listing".

Test conditions:
The same machine let WinSCP perform correctly a while ago.

The same WinSCP version also performs correctly on the other 3 machines. The connection address and user credentials are the same. All machines use the same router, 2 by air and to by cable.

Virus and firewall were disabled during the testing.

Internet Explorer's ftp client works fine with the same connection address and user credentials from the same machine where WinSCP fails to recieve "150 connecting to port xxxxx".

my guess
The WinSCP FTP client tries to establish a port for the server to send data, but for some reason this is not allowed on one of my machines.

my hope
Unfornately the error is on the machine I would like to use most, so I hope there is a solution.

Please post a full log file showing the problem (from both machines).

To generate log file, enable logging, log in to your server and do the operation and only the operation that causes the error. For posting extensive logs you may use pastebin or similar application. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you may email it to me. You will find my address (if you log in) in my forum profile. Please include link back to this topic in your email. Also note in this topic that you have emailed the log.

The line corresponding to the timestamp "22:06:31.096" is present when successful and missing when failing.
When failing, the dirlist is repeated in this test, although I only tried to connect and stopped WinSCP immediately after
having regained the UI control.


Thank you for your interest.
