Error listing directory '/'

2018-03-20 15:03

Hello,

When I try to connecting to a FTP server, WinSCP make a connection, start the session and when it try to read the remote directory an error happen.

Error:
Error listing directory '/'.
Could not retrieve directory listing
Command not implemented

It is the same with GUI or Powershell script.

It happens for two servers but works with a third.
It works with FileZilla :-) with all the servers.

I use WinSCP 5.13.8172 on Windows 7 Pro SP1.

Thanks.

Please attach a full session log file showing the problem (using the latest version of WinSCP). As well as verbose FileZilla log file for comparison.

To generate the session log file, enable logging, log in to your server and do the operation and only the operation that causes the error. Submit the log with your post as an attachment. 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 can mark the attachment as private.

Hello,

You will found 3 log files :
1 - "SS01---192.168.15.20.log", a WinSCP log file of a working connexion.
2 - "SS10---192.168.15.10.log", a WinSCP log file of an unworking connexion.
3 - "filezilla SS10.log", a FileZilla log file of the same connexion than 2 (but works).

Thanks.

SS10---192.168.15.10.log (4.22 KB)

filezilla SS10.log (6.06 KB)

You have to configure WinSCP to use an active mode (= not to use a passive mode):

On my side, it was caused by an invalid caracter "?" shown in a filename.
Throuhg an ssh connection I removed this caracter (mv filename? filename) and the problem was solved
