New Post: ExpectAction Problem

jimmychanga — Sun, 19 May 2013 14:28:55 GMT

Is it correct to assume that only two "choice" can be used in an ExpectAction?

I'm trying to issue a traceroute command on a cisco router without the host specified. This causes the CLI to ask for additional information, including target and source host. A total of 10 questions are asked before the command is successfully executed.

I thought I could just chain ExpectActions as so:

 ss.Expect(
                            new ExpectAction(@"Protocol \[ip\]: ", (s) =>
                                {
                                    ss.WriteLine("ip");
                                    _reply += s;
                                }),
                            new ExpectAction(@"Target IP address: ", (s) =>
                                {
                                    ss.WriteLine(dIpAddress);
                                    _reply += s;
                                }),
                            new ExpectAction(@"Source address: ", (s) =>
                                {
                                    ss.WriteLine(sIpAddress);
                                    _reply += s;
                                }),
                            new ExpectAction(@"Numeric display \[n\]: ", (s) =>
                                {

                            new ExpectAction(new Regex(@"\\*  \\*  \\*"), (s) =>
                                {

However, only the first two are ever processed.

I assume I'm doing this wrong. I appreciate any input.

New Post: Zlib compression support

tony1 — Thu, 16 May 2013 21:38:13 GMT

I followed the last comment mentioned in Issue 219, and I am able to get zlib compression working. Thanks olegkap! By the way, in addition to uncommenting lines in Zlibstream.cs, I also have to update variable CompressionAlgorithms in ConnectionInfo.cs.

I also want to use the assembly referenced from an assembly that is signed. I'd like to put in a request for you to sign the released assemblies. It allows people like us to download the binary as is and not have to keep a copy of the source code that we build ourselves. Thanks.

New Post: Zlib compression support

tony1 — Tue, 14 May 2013 21:11:14 GMT

Will SSH.NET support Zlib compression anytime soon? A SFTP server that I connect to require Zlib compression and SSH.NET gives error "Compression algorithm not found."

Is there a way for client to tell server disabling compression for the connection?

I would be happy to try out if there is an alpha version available. Thanks.

New Post: SftpClient.Exists and SftpClient.DownloadFile CREATE a file on server if file does not exist

trike007 — Tue, 14 May 2013 15:32:49 GMT

I managed to get it to work last night. In my case, for some reason, when using the pre-compiled .dll downloaded from here, it wasn't working. I ended up removing the reference to the DLL and re-referenced it to the project instead. Hoping that I could troubleshoot further with the project loaded. Once I re-compiled everything, the Exists() function works now.

New Post: SftpClient.Exists and SftpClient.DownloadFile CREATE a file on server if file does not exist

dwynne — Tue, 14 May 2013 15:27:29 GMT

We just don't call Exists(). Get() or DownloadFile() seem to work as expected.

trike007 — Tue, 14 May 2013 01:37:46 GMT

Did you happen to resolve this? I'm having the same problem with the exists method. It always returns true, and changing directory into an invalid path doesn't throw an exception either.

I'm also using sysax multi server.

Yes. In the ScpClient itself.

mwpowellhtx — Thu, 09 May 2013 13:45:02 GMT

This is in ScpClient itself? So it is a bug in ScpClient? Any chance that's finding its way back into the master/trunk, much less NuGet package? Thank ye!

New Post: No such File or Directory

jimtal001 — Thu, 09 May 2013 13:36:01 GMT

My file upload issue was finally resolved by adding the modified Upload method (redled, Feb 7, 2012) to the ScpClient.cs:

    public void Upload_2(FileInfo fileInfo, string filePath)
    {
        using (var input = new PipeStream())
        using (var channel = this.Session.CreateChannel<ChannelSession>())
        {
            channel.DataReceived += delegate(object sender, Common.ChannelDataEventArgs e)
            {
                input.Write(e.Data, 0, e.Data.Length);
                input.Flush();
            };

            channel.Open();

            //  Send channel command request
            string directoryPath = filePath.Substring(0, filePath.LastIndexOf('/') + 1);
            string filename = filePath.Substring(filePath.LastIndexOf('/') + 1);

            if (String.IsNullOrEmpty(directoryPath))
                channel.SendExecRequest(string.Format("scp -qt {0}", filename));
            else
                channel.SendExecRequest(string.Format("cd {0};", directoryPath) + string.Format("scp -qt {0}", filename));
            this.CheckReturnCode(input);

            this.InternalUpload(channel, input, fileInfo, filename);

            channel.Close();
        }
    }

New Post: No such File or Directory

mwpowellhtx — Wed, 08 May 2013 22:07:24 GMT

May be helpful, I ran an experiment with "local.txt" instead of "~/local.txt" and wouldn't you know it, I got the file transferred! Yay!

However, I would expect anything after the ":" in a typical Scp command would be fair game for Download remote file name, but who knew?

Perhaps some documentation around that issue would be a good thing.

mwpowellhtx — Wed, 08 May 2013 22:01:21 GMT

Any luck with this one? I too am finding the library WONDERFUL! THANK YOU! SSH works like a charm. Now I would like to copy a result that I redirected from the SSH command:

~/command --some_args >~/result.txt

Now via SCP, I say:

//The Configure and Connected are some extensions I cooked up to help it out by convention.
using (var client = new ScpClient(Host, User, Password).Configure().Connected())
{
  using (var fs = new FileStream("local.txt", FileMode.Create, FileAccess.Write, FileShare.Read))
  {
    //TODO: May hook up Downloading event (in fact I am, but for sake of example, the point is moot.
    client.Download("~/result.txt", fs);
    //ScpException: scp: ~/result.txt: No such file or directory
  }
}

However, like my colleague here, getting the same issue. It's there! I checked via Ssh. Is there a trick to making the Scp client work?

I could run the following and pick up the file: scp root@10.10.0.1:~/result.txt local.txt

I am working with the latest binary (SshNet 4.0 Binary, 2013.4.7) and still get the scp error: "No such File or Directory" when trying to upload a file using the scp client.

Any suggestions would be greatly appreciated.

Thanks

New Post: Sharing Download/Upload methods in BaseClient

roker002 — Tue, 07 May 2013 12:50:30 GMT

actually i'm writing a clr for download and upload file through ms sql.
Both scp and sftp support upload and download. It could be a good approach to write a virtual method for upload and download in BaseClient. So if i like to switch the protocol, i just need to get the base class and execute download/upload method.

right now, i need something like this.

Boolean isSftp = (transferProtocol.Value.ToLower() == "sftp");
            using (Renci.SshNet.BaseClient ssh = isSftp == true ? 
                (new Renci.SshNet.SftpClient(new Renci.SshNet.PasswordConnectionInfo(server.Value, 22, user.Value, password.Value)) as Renci.SshNet.BaseClient) :
                new Renci.SshNet.ScpClient(new Renci.SshNet.PasswordConnectionInfo(server.Value, 22, user.Value, password.Value))
            )
            {
                ssh.Connect();
                //sftp.ChangeDirectory(System.IO.Path.GetDirectoryName(source.Value));
                //if (sftp.Exists(source.Value) == false)
                //    throw new Exception(String.Concat("File: ", source, " do not exists on the remote server"));
                System.IO.FileStream file = null;
                using (file = System.IO.File.Exists(destination.Value) == false ? System.IO.File.OpenWrite(destination.Value) : System.IO.File.Create(destination.Value))
                {
                    if (isSftp == true)
                        (ssh as Renci.SshNet.SftpClient).DownloadFile(source.Value, file);
                    else
                        (ssh as Renci.SshNet.ScpClient).Download(source.Value, file);
                }
                //delete only if sftp
                if (delete.IsTrue == true && isSftp == true)
                    (ssh as Renci.SshNet.SftpClient).Delete(source.Value);

New Post: SCP copy to a specific folder

MarkusLanglotz — Tue, 07 May 2013 07:46:06 GMT

Hi,

i'm using 2013.1.27 and i try to copy a file from a windows to a linux machine.
My copy command looks like:

m_Scp.Upload(fi, sTargetDir + fi.Name);

where sTargetDir is "update/". My copied file pops up on the linux machine within directory ~/update/update/.
Looks like a bug.

If i use "./update/" everything works fine.

Thanks - Markus
