After upgrading on 4.xx (4.01 and 4.02) version my ftp stuck every time on directory listing and after while Operation timed out error (regular ftp and ftp-tls). On 3.8.1 version everything is working fine.
Here is log:

Default back to use STAT in 4e127d9. There is still a configuration issue with this server advertising a local adress for the passive data connection. File transfers will possibly fail.

ftp server is behind DynDNS service, and it's working fine with 3.8.1 - no problems with download/upload files.

It might work. If the server returns a local network address such as above in reply to PASV and you have connected to a non local address, it will ignore the address and use the address you connected to initially.

I upgraded to (8537) and it is partially working. I now can access listing and some dirs but some stucks again.

I just checked in local network and everything is working fine. It seems that there is an issue with "..it will ignore the address and use the address you connected to initially." I tried also with some other clients and ftp from terminal and server is responding Passive mode is OK.
Filezilla (working) responds with:

Response:	227 Entering Passive Mode (192,168,100,51,27,105)
Status:	Server sent passive reply with unroutable address. Using server address instead.

When STAT does not return any file we also request a directory listing with LIST for interoperability reasons (some servers do not send anything meaninful for STAT). LIST does need a seperate data connection for the transfer.

The log message from Filezilla is the same what I suggested above what Cyberduck would do as well but was indeed not previuosly the case. Not trust the local address returned by the server for PASV. I have fixed this with 05d3f6a.

Thank you, you are really great (and extremely fast). I am almost embarrassed to bother you more but I now noticed one more issue - in one moment after uploading file and disconnecting on next session I can't delete/move/rename file.

I don't think that I'm anonymous (anonymous is disabled) and permissions are right. ;)
It somehow thinks that I'm anonymous user.

That is most certainly a bug with the server. Please contact the vendor.

I don't think so. It just happens with Cyberduck. I tried several Mac and Win clients and also terminal ftp on Mac and Debian. Everywhere else works without any issues.
I now receive error "553 Users may not upload files." and "550 Sorry, users are not allowed to create directories". version (8542)
With 3.8.1 everything works as it should.

The issue is we are no more issueing a CWD command to change the current working directory when working with absolute paths. It is a Pure-FTPd bug if it can't cope with that. Can you please open an issue with the above transcript in their issue tracker.
