New Post: SCP copy to a specific folder

Same problem here:

trying to copy from Win7 into subfolder in Mac OS X 10.7.5 (11G63)

with

      using (var transfer = new ScpClient(connectionInfo))
      {
        transfer.Connect();
        transfer.Upload(new System.IO.DirectoryInfo("D:\\Temp\\Test"), "test/testsub");
        transfer.Disconnect();
      }

results in "scp: error: unexpected filename: test/testsub

Same with fully qualified path:         transfer.Upload(new System.IO.DirectoryInfo("D:\\Temp\\Test"), "/Users/demo/test/testsub");

results in "scp: error: unexpected filename: /Users/Demo/test/testsub

Changing InternalUpload to

        private void InternalUpload(ChannelSession channel, PipeStream input, DirectoryInfo directoryInfo, string directoryName)
        {
            this.InternalSetTimestamp(channel, input, directoryInfo.LastWriteTimeUtc, directoryInfo.LastAccessTimeUtc);

            var dirPath = Path.GetFileName(directoryName);
            this.SendData(channel, string.Format("D0755 0 {0}\n", dirPath ));
            this.CheckReturnCode(input);

            //  Upload files
            var files = directoryInfo.GetFiles();
            foreach (var file in files)
            {
                this.InternalUpload(channel, input, file, Path.Combine(dirPath, file.Name));
            }

            //  Upload directories
            var directories = directoryInfo.GetDirectories();
            foreach (var directory in directories)
            {
                this.InternalUpload(channel, input, directory, Path.Combine(dirPath,directory.Name));
            }

            this.SendData(channel, "E\n");
            this.CheckReturnCode(input);
        }

does the trick ... mostly.

It however still fails if the target path consists of more than one folder and the first folder of the chain is missing in the target system.

doing an explicit
                channel.SendExecRequest(string.Format("mkdir -p \"{0}\"", directoryName));

within its own channel

            using (var input1 = new PipeStream())
            using (var channel1 = this.Session.CreateChannel<ChannelSession>())
            {
                channel1.DataReceived += delegate(object sender, Common.ChannelDataEventArgs e)
                {
                    input1.Write(e.Data, 0, e.Data.Length);
                    input1.Flush();
                };

                channel1.Open();

                channel1.SendExecRequest(string.Format("mkdir -p \"{0}\"", directoryName));

                channel1.Close();
            }

solves this as well - not overly elegant, but functional :)
