Please Explain Basics: Which server is working?

#1 Post by abrogard » 2023-06-17 04:10

I have win10 with IIS and I set up ftp server on it but it didn't work.
a client ftp would report connected but 'server closed the connection' immediately.
even when I took the firewall down to check it wasn't it.
and rechecked all the port forwarding.

so I installed filezilla server.
and it performed exactly the same way. yesterday.

today it is suddenly making a connection quite happily either localhost (I'm working on that same machine) or my static IP, either one, and just failing on 'directory listing'.
It apparently cannot list the directory.

And I've suddenly realised I don't know which server the clients are trying to connect with: filezilla or IIS ?

Can anyone help me untangle the mystery? I'm pretty unknowing, I know. Amateur entirely.

Here's the client output - I note that 'using server address instead' and I don't know what that is - which server, what address?

Status: Connection established, waiting for welcome message...
Status: Initializing TLS...
Status: TLS connection established.
Status: Logged in
Status: Retrieving directory listing...
Status: Server sent passive reply with unroutable address. Using server address instead.
Command: MLSD
Response: 550 Couldn't open the file or directory
Error: Failed to retrieve directory listing

I wanted to edit it with new information but I couldn't see how to.

I tried to log in from a linux mint box on the same lan and got in alright. I can be sure I'm getting into the Filezilla server. But I don't see how because I didn't specify the port I'm told Filezilla server is listening on: 14148 so I'd expect the client to have been trying to talk to port 21. It was from the terminal session on mint.

but it claimed to have connection and passed the username/password thing but then failed on directory listing:
(I suppose I better hide my actual IP)

Port 14148 is for the Administration Interface to connect to, not the FTP client, unless it's changed. Port 21 is for the FTP protocol.

As for what concerns the errors you're getting: have you set up mount points for the user "dave" you are logging in with?
