winscp passive mode ports

PORT - In PORT mode, the FTP client gives WS_FTP Server an IP. In the active mode, the client starts listening on a random port for incoming data connections from the server (the client sends the FTP command. To Enable Active/Passive Mode FTP The data connection mode can be modified in WinSCP client as follows: Under Stored sessions, select doge.ymyjsxyk.info and.

Some servers and also firewalls and routers on the way between the client and the server disconnect clients if they do not receive any data from it within a defined period. In the Keepalives box, you may order WinSCP to send some dummy data in regular periods to avoid being disconnected.

This period is defined with Seconds between keepalives. WinSCP implements two methods for keepalives. Some servers may be configured not to count these packets as data and thus they will still disconnect clients sending them. As an alternative WinSCP can send dummy commands of the transfer protocol instead. For SCP it is implemented as echo command. Note that keepalives are not always helpful.

They help if you have a firewall which drops your connection after an idle period; but if the network between you and the server suffers from breaks in connectivity then keepalives can actually make things worse. If a session is idle, and connectivity is temporarily lost between the endpoints, but the connectivity is restored before either side tries to send anything, then there will be no problem — neither endpoint will notice that anything was wrong.

However, if one side does send something during the break, it will repeatedly try to re-send, and eventually give up and abandon the connection. Keepalives can make this sort of problem worse, because they increase the probability that WinSCP will attempt to send data during a break in connectivity.

Other types of periodic network activity can cause this behavior; in particular, re-keys can have this effect. Therefore, you might find that keepalives help connection loss, or you might find they make it worse, depending on what kind of network problems you have between you and the server.

This option allows the user to select between the old and new Internet protocols and addressing schemes IPv4 and IPv6. The default setting is Auto , which means WinSCP will do something sensible and try to guess which protocol you wanted. So, usually there are no problems when opening the control connection.

Where FTP protocol is more complicated comparing to the other file transfer protocols are file transfers. While the other protocols use the same connection for both session control and file data transfers, the FTP protocol uses a separate connection for the file transfers and directory listings. In the active mode, the client starts listening on a random port for incoming data connections from the server the client sends the FTP command PORT to inform the server on which port it is listening.

Nowadays, it is typical that the client is behind a firewall e. For this reason the passive mode was introduced and is mostly used nowadays. It is a default for WinSCP too. Using the passive mode is preferable because most of the complex configuration is done only once on the server side, by experienced administrator, rather than individually on a client side, by possibly inexperienced users.

In the passive mode, the client uses the control connection to send a PASV command to the server and then receives a server IP address and server port number from the server, which the client then uses to open a data connection to the server IP address and server port number received. Use Passive mode session settings to toggle between the active and the passive mode.

With the passive mode, most of the configuration burden is on the server side. The server administrator should setup the server as described below. Typically, the FTP server software has a configuration option to setup a range of the ports, the server will use. It is common, that the FTP server is not configured properly and provides its internal IP address, that cannot be used from a client network.

By default WinSCP detects, when an unroutable IP address is provided, and uses a server control connection address instead.
