An error occurred while opening the folder on the FTP server. Check whether you have the permission to access this folder.

When you use ftp to upload data, you will often encounter a prompt that "open ftp" has no permission. This is because your browser has set a firewall. The following is the correct setting process:
1. Open an IE browser first (if multiple browsers are opened, close it ).
2. Click "Tools"> "Internet Options"> "advanced"
3. Find the Passive FTP (for firewall and DSL modem compatibility) and remove the preceding check box.
4. Click OK and close IE.
5. open "my computer" and enter the IP address in the address bar and press Enter. A dialog box is displayed, asking you to enter the user name and password. after entering the user name and password, you can copy your compressed file to FTP.

The following describes how to upload data using the FTP software flashfxp.
1. Open the software, open "options"> "parameter settings"> "proxy", remove the "use passive mode" check box, and click OK.
2. Click the lightning icon on the right. Enter the IP address in the server bar, enter the user name and password, and click Connect.

On the left side of the software is your local computer, and on the right side is the server. You can drag the data set you want to upload to the right.

When copying a file to FTP, the dialog box is displayed: "An error occurred while opening the folder on the FTP server. Check whether you have the permission to access the folder. After you click OK, the folder can still be uploaded. The running platform is: linux9.0 + vsftp2.0

Solution:

The FTP protocol can work in two ways: Port and PASV. The Chinese meaning is active and passive.

The active connection process is that the client sends a connection request to the FTP port of the server (21 by default). The server accepts the connection and establishes a command link. When data needs to be transmitted, the server sends a connection request from Port 20 to the idle port of the client and establishes a data link to transmit data.

PASV (passive) connection process: the client sends a connection request to the FTP port of the server (21 by default). The server accepts the connection and establishes a command link. When data needs to be transmitted, the client sends a connection request to the idle port of the server and establishes a data link to transmit data.

Finally, modify the settings here and remove the check box.

Method:
 

1. Open the IE menu "Tools"-> "Internet
Option ";
2. Click the "advanced" tab card;
3. Remove the check box before "use Passive FTP (for firewall and DSL modem compatibility)" under the "Browse" node.

Because the server actively connects to the client when data is transmitted by port, if the client is behind the firewall or NAT gateway, the file cannot be transmitted by port with the FTP server on the Internet. In this case, PASV is required. Almost all FTP client software supports these two methods. A special example is IE, which uses port by default. If you want to enable PASV in IE, open IE and select tools from the menu.
-> Internet option-> advanced, hook up before "use Passive FTP" (ie6.0 or above is required ).
