filezilla failed to create listen socket after ftp over tls

One solution is to configure your FTP server to use a small range of ports, or just a single port and create a firewall rule to open those ports. With FTPS the firewall can't snoop on the COMMAND channel any more. Since you rightfully use TLS encryption that doesn't work. It will recognise the PASV port that will be assigned and open up the firewall dynamically and allow traffic between that particular client and the PASV port used in that session. Since FTP is clear text protocol your firewall can scan the traffic on the command connection on port 21. Normally with a reasonably intelligent firewall that second port is opened automatically. You problems seem to indicate you don't have that second port open in your firewall. With passive FTP the second connection is to a randomly assigned available TCP port above 1024. You have port 21 the command and login connection and a second connection, the data connection. It uses two TCP connections, rather than just the one most protocols use.

Status : Connection failure with 'ECONNREFUSED - Connection refused by the server'.I've set up a self signed certificate in FileZilla server and enabled FTP over TLS. One of thing I've noticed is that when I'm trying to reach the FTP by a ftp client, I have this error Status : Connection to 192.168.79.2:21. I checked the event log and it is not saying much neither, as the only log happens at 03:27 as you can see and the ftp server stopped at 05:45Am. I raised the filezilla server log and the trace below were the only thing, I was able to see (001170) 05:45:23 - project_mgt (192.168.79.8)> STOR DC04-Project Indicators.xlsįailed to bind the listen socket on port 990 to the following IPs: ::0 0.0.0.0 My filezilla FTP server stops after some time, the time is varying from 5 hours to 24 hours.
