FTP connection error: PASV mode failure & Data socket Error

When I use ftp to connect to the server, I find that the previous normal connection prompts a data socket error today. The connection is rejected and the pasv mode fails. I tried the port mode, next, I will sort out the solutions for my friends.

Win2003, which was previously built with VirtualBox, will still be used occasionally. It is necessary to test FTP and asp and as.net under IIS. After FTP is set up with IIS manager, when the Host machine uses flashfxp to connect to the virtual machine, there are always some errors, such:

◦ FTP connection is very slow. It is reasonable to say that it is the same Intranet, and the speed is fast.
Failed data Socket error: Connection timeout
◦ PASV mode failed
Check. It turns out that the VirtualBox network connection mode is related to the FTP transmission protocol PASV mode and PORT mode. The specific reason cannot be understood. It is too deep. The problem is solved by setting the steps.

 

Modify as follows.

How to change the FTP client mode of Internet Explorer

1. Start Internet Explorer.
2. On the Tools menu, Click Internet Options ".
3. Click the "advanced" tab.
4. Under "Browse", click to clear the "enable folder view for FTP site" check box.
5. Click to select the "use Passive FTP (for firewall and DSL modem compatibility)" check box.
6. Click OK ".
If you select the "enable folder view for FTP site" check box, Internet Explorer performs the same way as the "standard" mode FTP client, this is even if you have selected the "use Passive FTP" check box. If the "enable folder view for FTP site" check box is cleared and the "use Passive FTP" check box is selected, Internet Explorer will behave like a "passive" mode FTP client.
