I'm at my wit's end - I'm hoping someone can help me out here. I've been running ISPConfig3 for over a year. Today my FTP access has decided to just quit working. I'm seeing the same thing over and over in my FTP Client (FileZilla) - MLSD timeouts: Code: Status: Connection established, waiting for welcome message... Response: 220---------- Welcome to Pure-FTPd [privsep] [TLS] ---------- Response: 220-You are user number 1 of 50 allowed. Response: 220-Local time is now 16:47. Server port: 21. Response: 220-This is a private system - No anonymous login Response: 220-IPv6 connections are also welcome on this server. Response: 220 You will be disconnected after 15 minutes of inactivity. Command: USER XXXXX_base Response: 331 User XXXXX_base OK. Password required Command: PASS ************ Response: 230-User XXXXX_base has group access to: client1 sshusers Response: 230 OK.

Status: Connected Status: Retrieving directory listing... Command: PWD Response: 257 "/" is your current location Command: TYPE I Response: 200 TYPE is now 8-bit binary Command: PORT 72,58,234,181,172,199 Response: 200 PORT command successful Command: MLSD Error: Connection timed out Error: Failed to retrieve directory listing I've tried everything I can think of - Passive & Active mode, opening a different set of ports on the router, upgrading FileZilla, router firmware upgrade, restarting Pure-Ftpd, changing the Passive ports in Pure-Ftpd (including opening the firewall for said ports), using a non-secure connection, etc and so on. I've been at this for 5 hours. No matter what I try, I can't get a connection. It always times out at the MLSD command. I have to get this site updated today and I'm completely stumped. Does anyone have any ideas? Even a non-FTP solution at this point.
