PASV 10 is enabled in SEVER U

To be specific, the question is too vague.

After you create a new account.

Click on it, find the "Home Directory" under the "Account" option on the right side of Sever-U, set the storage folder, and then find the "Directory Access" to set the permissions.

For example: Read, Write, Append checkbox.

Once you've set it up, just click Apply.

In passive FTP, both command and data connections are made by the client, which solves the problem that the inbound connection from the server to the client's data port is filtered out by the firewall.

When an FTP connection is opened, the client opens two arbitrary unprivileged local ports. The first port connects to port 21 of the server, but unlike active FTP, the client does not submit the port command and allows the server to connect to and from its data port, but instead submits the pasv command.

If you choose whether to log in to the FTP server in PASV mode or port mode, you can choose between the FTP client and not the FTP server.

The FTP protocol works in two ways: port mode and PASV mode, which means active and passive in Chinese.

In port mode, the client sends a connection request to the FTP port of the server (21 by default), and the server accepts the connection and establishes a command link.

When data needs to be transferred, the client uses the port command on the command link to tell the server: "I opened the *** port, you come and connect to me". So the server sends a connection request from port 20 to the *** port of the client, and establishes a data link to transmit data.

In PASV (passive) mode, the client sends a connection request to the FTP port of the server (21 by default), and the server accepts the connection and establishes a command link.

When data needs to be transferred, the server uses the pasv command on the command link to tell the client: "I opened the *** port, you come and connect to me". The client then sends a connection request to the *** port of the server and establishes a data link to transmit the data.

As can be seen from the above, the command link connection method is the same for the two methods, while the data link establishment method is completely different. That's where the complexity of FTP comes in.

"Server Settings and Restrictions", "Settings", PASV Port.

It's not the same as the previous setting. It is set individually.

Do the mapping ahh

If sever-u ever works, then a service starts. Before deleting, you need to stop the service and look for it in the service list"sever-u\"The word for the clothes teases the pants, stop it, and you can remove it. However, the general green version of the software will provide an uninstall method, you go to the ** folder to look for it, and follow its instructions.

Because the service is deleted directly after the service is stopped, the registration is not cleared, and an error may occur in the future. If not, you can easily do it with a tool like Super Bunny.

The process should be serv-u deletion, if it doesn't work, cancel serv-u's startup in the startup item, restart the book should be able to be deleted, and if you install it, there should be serv-u in the service, first stop the state sleepy, and then delete it.
