I referenced to 9380 change set In my project

but found an exception occured at sftp.dispose() sometimes

so I wan't change my project to the newest version 10805

but found i can't send any sshcommand success.

my code is similar to below

using (var client = new SshClient("", "rootname", "rootpassword"))
    var result = ExecuteTestCommand(client);


private static bool ExecuteTestCommand(SshClient s)
   var testValue = Guid.NewGuid().ToString();
   var command = string.Format("echo {0}", testValue);
   var cmd = s.CreateCommand(command);
   var result = cmd.Execute(); // exception occur at here
   result = result.Substring(0, result.Length - 1);

   return result.Equals(testValue);

i go into the SshCommand.Excute(), finally find exception throwed at Session.WaitHandle(WaitHandle waitHandle)

after excute var index = EventWaitHandle.WaitAny(waitHandles, this.ConnectionInfo.Timeout);

index's value is 0


is there anthing wrong with the code or my call method is incorrect?

can anybody help me?

I could take a look at it only in couple weeks, unfortunately.

Meanwhile, can you post more specific exception that you get? I f possible of course.

im having similar problem.

I have Sftp server installed on dev system so it transfers the file but it fails on Disconnect

Using Renci.SshNet.Net35

After doing


  getting Socket exception  in


partial void SocketRead(int length, ref byte[] buffer)


line 71 :var receivedBytes = this._socket.Receive(buffer, offset + receivedTotal, length - receivedTotal, SocketFlags


this._socket is null at that moment.

Can you reproduce it every single time?

Does it happens with all servers or only with specific SSH server implemention?
