When FTP uploads ASP files, there will be a red prompt error every time: connection aborted.

Are you using free space? Maybe it doesn't support FTP upload .. see if it is suitable for uploading on the network in the station. ..

Firewalls are very influential.

Then you can check the reason according to the prompt code. The meanings of different codes are as follows:

530, indicating that the password is wrong.

550, which means there is an error in the address. Maybe the thief didn't change it.

1 10 Restart the mark reply. In this case, the text is accurate, not reserved for a specific implementation; It must read: the tag yyyy = mmmm, where yyyy is the user process data flow tag, and the equivalent tag of the mmmm server (note the spaces between tags and the restart flag response. In this case, the information is accurate and does not need special treatment; It can be seen as follows: in the tag yyyy = mmm, yyyy is the user process data stream tag, and mmmm is the corresponding tag on the server side (note the space between the tag and the equal sign).

Two working modes in FTP

FTP is a file transfer protocol that supports two modes, one is standard (active mode) and the other is passive (PASV, passive mode). The client of standard mode FTP sends a PORT command to FTPserver. Passive FTP client sends PASV command to FTP server.

Here are how these two methods work:

The FTP client in standard mode first establishes a connection with TCP 2 1 port of FTP server, and sends commands through this channel. When the client needs to receive data, it sends port commands on this channel. The PORT command contains the port that the client uses to receive data. When transmitting data, the server sends data through its own TCP 20 port. The FTP server must establish a new connection with the client to transmit data.

When establishing control channel, passive mode is similar to standard mode. When the client sends a PASV command through this channel, the FTP server will open a random port between 1024 and 5000, and inform the client of the request to transmit data on this port, and then the FTP server will transmit data through this port. At this point, the FTP server no longer needs to establish a new connection with the client.

The current FTP software, including versions above IE5, already supports these two modes. Generally speaking, some FTP client software is relatively easy to set up. There is generally a PASV option, such as CuteFTP. There are two transmission modes: standard and PASV. You can choose by yourself. In addition, if you want to set PASV mode in IE, you can choose Tools-Internet Options-Advanced-Enable Folder View for FTP sites, otherwise you can use standard mode.

Many firewalls are not allowed to accept external connections when they are set up, so in many cases, the standard mode of FTP is restricted when the machines in the intranet go out through the firewall, because TCP 20 from the server can not establish new connections with the clients in the intranet, which leads to failure to work. Of course, it can also be set successfully. First, you should create a rule that allows internal IP to connect to the 2 1 port of external IP. The second is to prohibit the TCP 20 port of external IP from connecting with internal IP.

Value name: MaxUserPort data type: REG_DWORD value: 65534.

So if there is a firewall or you are afraid of configuration trouble, it is best to adopt PASV mode, but if there is really a high demand for security, it is recommended to adopt standard mode.
