If you load the ip_conntrack_ftp module then it may track the FTP control connections and mark incoming data connections as "related" - so you can add an iptables rule to allow packets from "related" connections on ports 1024 or above as well as accepting those for "established" connections. The settings for controlling the data connection ports are pasv_min_port and pasv_max_port, though that may not be needed. if your ssh private key is in the default directory, the software may find it automatically. ssh/ided25519.pub) to the sftp-server-admin. If you don't have a specific requirement for FTP (compatibility with an existing service you can not change, or users who only have access to an FTP client, or similar) I strongly recommend usnig SFTP/SCP as provided by most SSH daemons - this removes the multiple arbitrary connections problem (everything is done over one duplex TCP connection, usually on port 22), and is significantly more secure too. if you use an sftp to connect to an sftp server, you should generate an ssh keypair (ie on unix: ssh-keygen) and provide your the public key (ie. This splitting of the control and data connections often causes firewall problems. If you were not using passive mode there would be a similar problem in the other direction: the server would need to be able to open a connection to the client on a port specified be earlier commands. Check what thee are (or set them explicitly to a range of your choice) and then open those ports in your firewall rules as you already have for the FTP control connections. IIRC wsftp has a couple of configuration settings that control the range of ports it might expect data connections on. #chroot_list_file=/etc/vsftpd/chroot_listĪt this point the FTP server is expecting the client to open a new connection to transfer the data by connecting via TCP on port 15014 (59*256+0) - either the firewall on the server or the client (or somewhere between) is likely to be rejecting this connection. I cannot view the folders or the directories on the FTP server. ![]() Response: 227 entering passive mode (192.168.8.5,59,0).Īnd it stops right there, then connection timeout. ![]() Status: connection established, waiting for welcome message The -O option redirects the output, if any, to /dev/null so it is not written to a file not to stdout.
