Time-Out on Session.Open

2012-04-13 17:38

Hi Everybody.
I'm using the component for first time.
I copied the C# example in my class and passed the parameters. When pass by session.Open(sessionOptions), after a long time I get "Time out". Do you have any idea about this waiting time on Session.Open?

Hi @martin, how is it going?
After I set Session.DegugLogPath I received the error

Object reference not set to an instance of an object

in Session.Open command.

Whole method until this point:

SessionOptions sessionOptions = new SessionOptions {
    Protocol = Protocol.Sftp,
    HostName = ConfigurationSettings.AppSettings["Host"],
    UserName = ConfigurationSettings.AppSettings["UserName"] ,
    Password = ConfigurationSettings.AppSettings["Pass"] ,
    SshHostKey = ConfigurationSettings.AppSettings["HostKey"] 
};
 
using (Session session = new Session())
{
    // Connect
    session.DisableVersionCheck = true;
    session.Timeout = new TimeSpan(0, 2, 0);
    session.SessionLogPath = @"C:\TEMP\logWinSCP";
    session.ExecutablePath = @"C:\Projetos\tools\WinSCP\WinSCP.exe";
    session.IniFilePath = @"C:\Projetos\tools\WinSCP\WinSCP.ini";
 
    session.DebugLogPath = @"C:\TEMP\logWinSCP";
    session.Open(sessionOptions);

First, why are you setting DisableVersionCheck? Looks suspicious.

Also, please post a callstack of the exception you are getting. I'm not getting it with your code.

"Timeout waiting for WinSCP to respond" in Session.open

2012-08-30 22:19

The Session.open(SessionOptions) is throwing a "Timeout waiting for WinSCP to respond." error when executed in our production server.

The same code works perfectly fine in our Development and local servers.

However, we are able to manually execute the WinSCP.exe GUI and connect to the FTP server in our prod server

Kindly advise if there is anypermission related settings we need to consider.

Following is the DebugLog

Same error

2021-10-31 12:10

Hi,

I am getting the same error.

Log Linked Files Archive - Started - 10/31/2021 2:20:14 AM
Error: System.TimeoutException: Timeout waiting for WinSCP to respond - WinSCP has not responded in time. There was no output. Response log file E:\AbacusAutoCheck2\log\winscp.log was not created. This could indicate lack of write permissions to the log folder or problems starting WinSCP itself.

Log Linked Files Archive - Finished - 10/31/2021 2:21:21 AM

This is the error (call to log linked files procedure) I am getting. According to this article, (https://winscp.net/eng/docs/message_library_timeout_waiting_to_respond), I supplied the user credentials, but now I am getting

Win32_exception The stub received bad data error.

Googling suggest the process domain is not specified, but I don't see a way to set that.

The task runs under Task Scheduler using a service account. Manually running the task (VS Studio) under my user account seems fine.

Any clues? I have attached the debug log for reference. For this program, there is no file transfer. It only does a directory listing.

RemoteDirectoryInfo directory = session.ListDirectory("/data");

Regards,
Eddy

That worked, however, I am still getting sporadic time out issues. I suspect it's due to the RAM limitations. I increased the timeout to 120 seconds. However, it seems the time out exception occurred after a minute or so. Any thoughts?

SessionOptions sessionOptions = new SessionOptions
{
    Protocol = Protocol.Sftp,
    HostName = "************",
    UserName = "atzzz001",
    Password = "******",
    SshHostKeyFingerprint = "********************",
    Timeout = TimeSpan.FromSeconds(120)
};

You have to set Session.Timeout.

@eduard.torres10: That's not an error. Please post the actual error. Or even better a complete log file.
