• Winscp Optimize Buffer
• Latency

I am running a remote script with WinSCP that results in a lengthy wait between terminal responses.

• Hepls you to know more and more about win scp. Winscp – Free SFTP, SCP and FTP client. Disabling session option Optimize connection buffer size disables unlimited SSH window to overcome bugs in some older version of OpenSSH. WINSCP key features. Graphical user interface.
• The Connection page on the Advanced Site Settings dialog. The Optimize connection buffer size. By the Server response timeout you define how long should WinSCP.
• My.net app based on winscp stopped working. While uploading a bigger file, I get. WinSCP.SessionRemoteException HResult=0x80131500 Nachricht = Terminated by user. Copying file 'test.mp4' fatally failed. Copying files to remote side failed.
• You can use raw site settings to setup advanced site settings. For both cases, you can just configure the advanced settings on Advanced Site Settings dialog and have WinSCP generate the code for you. Optimize connection buffer size: 0 = Off, Any positive value = On.
• Note If the problem repeats, try turning off 'Optimize connection buffer size'. This will allow you to use Winscp to transfer files from the VCSA using SCP.

I get all the intermediate output from the session with the session.OutputDataReceived() event, until it comes to a point where the remote host is silent for > 30 seconds before continuing.

Cannot establish session attempt to upload files to Infoblox using WinSCP. The error: Host is not communicating for more than 15 seconds. If the problem repeats, try turning off 'Optimize connection buffer size' Putty to port 22 works fine. Go to Solution. Can you provide more information.

This is the conversation with the remote host as captured by OutputDataReceived:

After 'Updating AAA...success', I expect three more lines, after various wait times.

I'm assuming the remaining output lines are from the remote host, suggesting the WinSCP session is about to time out.

I need the session to stay alive to the host until the process is complete, and I tried setting 'TimeoutInMilliseconds=60000' in the SessionOptions, but the result was then

The remote script ends with rebooting the remote host, so there is no real exit or return to a command prompt, just a final 'Rebooting AAA' message, which I can use to signal the end of the process. How can I make WinSCP hold this session up until it completes?

Edit 2016/11/28

I have a try/catch around the session.ExecuteCommand() line. When I use session defaults, and the script reaches the pause (of around 70 seconds), I see these strings returned in OutputDataReceived:

If I use the extended session option 'TimeoutInMilliseconds = 900000', I see this:

Meaning, the ExecuteCommand() method is throwing the exception, and it only waits 60 seconds for the script to send data; the TimeoutInMilliseconds apparently only applies to the session, not to the ExecuteCommand timeout.

Here is the WinSCP debug log for the 'default' session:
