New Post: "Session operation has timed out" error?

Hi,

I am trying to use this library to upload a file via SFTP, and it connects fine and even puts an empty file onto the SFTP server, but then it just sits there and eventually times out with a session operation has timed out exception. The code is basically as follows:

            var uri = new Uri(remoteUri);
            if (uri.Scheme == "sftp") {
                // Upload the file using sftp over SSH
                var host = uri.Host;
                var userInfo = uri.UserInfo.Split(':');
                if (userInfo.Length > 1) {
                    var username = userInfo[0];
                    var password = userInfo[1];
                    using (var sftp = new SftpClient(host, username, password)) {
                        sftp.Connect();
                        using (var file = File.OpenRead(localFile)) {
                            sftp.UploadFile(file, uri.LocalPath);
                        }
                        sftp.Disconnect();
                    }
                } else {
                    throw new ArgumentException("Unable to parse username and password from URI");
                }
            }

Any idea what would cause this? I have debugged into a debug build of the source code (built with VS2012) and it gets stuck as soon as it attempts to send any data?
