Filezilla client not able to browser into folder structure but i can through windows explorer

#1 Post by apommier » 2020-03-11 22:28

I've installed the Filezilla server on several hyper-v windows 2019 installs. Once the server settings are setup i am able to connect to the server but i cannot browser the directory structure properly.

The initial connection goes through and shows the root folder selected, i then click into one of these folders to go deeper and it hangs. On other installs it's unable to retrieve the directory listing.
I've played around with the FTP ports and other settings but am unable to get the filezilla client to browse correctly. Weird thing is i can browse fine through windows explorer.

I have all necessary ports open in windows firewall and my physical firewall.

Response: 150 Opening data channel for directory listing of "/history"
Response: 425 Can't open data connection for transfer of "/history"
Error: Failed to retrieve directory listing

1. Why are you using Active (PORT) mode? It is firewall unfriendly.

2. Consider using FTP over TLS (even with a self-signed certificate). It is much more secure and firewalls cannot interfere.

3. Did you delete or modify the Welcome message? If not, you might not even connect to FileZilla Server, but possibly the default Microsoft one.

@boco

When i change the settings to use FTP over TLS the filezilla client can't even connect. Weird thing is i can connect via windows explorer fine.
I have modified the welcome message.

Definitely some firewall interfering with the connection. Remove the offending firewall, or firewalls and try again.

If that were the case i would also have difficulties browsing through windows explorer which i don't. The issue is solely using the filezilla FTP client. I've added firewall rules for the client on my workstation's firewall and the server has all necessary ports open

Windows Explorer uses a different, most insecure protocol variant. Try a different FTP client that uses a secure protocol.
