Stack Gives Back WinSCP is a Windows application for transferring files via fto or scp to remote host. A feature not many take advantage of is the ability to create automation scripts that can execute these transfers as silent batch jobs. When dealing with SCP sessions, we need to set a hostkey value in order to meet security concerns, so we will go into detail on how to retrieve and provide that value.
You should see a directory list of ftp. For a full list of command available see the winscp script commands. The scp commands used to connect and run commands on a remote host follow the same pattern as the example above. Once a transfer is in the transfer queue, you can perform other activities in WinSCP includes initiating another transfer!
The transfer queue is a great way to perform various transfers at once and to queue them all up instead of waiting for each transfer to complete. For each background transfer, WinSCP opens a separate connection to the server using the same session options you defined when creating the session. These new connections are kept in the background and reused for future transfers. By default, the transfer queue will only attempt to perform two transfers at once.
You can change this behavior by opening the Preferences menu and changing the Maximal number of transfers at the same time under the Background section, as shown below. In the Background transfers Preferences menu , you can change the behavior of the transfer queue.
To create saved connections or what WinSCP refers to as sites , you can save connections to remote hosts so that you can simply browse to a site and connect. Click the Session menu as mentioned in the Connecting to a Remote Host section and provide all of the necessary connection information.
Next, provide a Site name for the saved connection and an optional folder and click OK to confirm. The properties are now saved in a site. After you click on Login, the connection to a new site begins. Select Yes to add the server host keys to your system cache so that WinSCP can trust the remote host.
Maybe you need to edit properties of an existing site like changing the hostname or username perhaps, you can do that too in WinSCP. Click on the Session menu item which will bring up the Login window again. You will see all of the saved sites in the Login window. The previously greyed-out options will now be available to edit. To rename or delete a site, click on the Delete or Rename menu item. You can even create copies of sites that perhaps share the same username by clicking on Clone to New Site.
WinSCP stores sites in files. If you need to modify settings of a site in the files themselves, here you can edit the raw settings and modify advanced settings you might not need too often.
Now what? You must manually transfer over those sites. To do that, WinSCP has a concept called configurations that allow you to backup and restore all of your sites. Open the Site Manager and click on the Tools button. Importing a configuration will overwrite all existing sessions! You can import all of those sessions directly into WinSCP.
Right click anywhere in the left site menu and click on Import Sites. Select a source to import from. WinSCP provides a session logging feature that does just that. Passwords are never recorded in any log unless you choose the Log passwords and other sensitive information checkbox.
To enable session logging, check the Enable session logging on level checkbox and provide a logging level. In the session log, WinSCP logs events in an instructured way that varies by the protocol the session is using. The session log is typically good for troubleshooting purposes. Limit log sizes by defining the maximum size a log file can grow by enabling the Rotate log files after reaching checkbox. In this dropdown, you can use K , M , and G to represent bytes.
If a log file grows too large, WinSCP will create a copy with an extension. WinSCP will not record all previous session history in the log file. The session log records logs in an unstructured text file. But, if you need a more structured approach for future parsing, you should tick Enable XML logging to file. This format includes less information than the session log but can be used for scripting purposes.
Perhaps, you routinely work with a set of sites you have open all day. You typically need to access these hosts in some way. Rather than opening up each site every day, you can save them all in a workspace to save all connected sites as one. Perhaps you have dozens of sites open and want to immediately come back to them at one time.
To do that, click on the Session menu and choose Save Workspace. WinSCP will then prompt you for a place to save the workspace file. If you select this option, WinSCP will create a desktop shortcut with the following target. This target will open a workspace called My Workspace. Once you have saved a workspace on your computer somewhere, you need to open it somehow.
Open Site Manager, find the workspace in the left pane, right-click on the workspace, and select Login. The workspace saved when WinSCP was closed the last time is automatically selected when the Login dialog opens. Using features like the built-in command-line box, custom commands, and even Putty, you can quickly run various short commands on a connected host. To access the feature, click on the Options menu and select Command Line , as shown below. Once you have the Command box open, type in any terminal command you wish and WinSCP will execute it on the remote host.
For example, type ifconfig , as shown below, to discover IP address information on the remote host. Do not run commands that require user input. Custom commands templatize common actions. For example, running a custom command such as cat "! Or, you can just have a complex SSH command to save and run later. To set up and run custom commands, click on the Commands menu and then on Static Custom Commands.
