Hello guys. Program compiled with Lazarus / FreePascal under Linux tested on a Raspberry Pi. This error message appears even though the libtgputty.so library is included in the same directory.

How to get a list of files in a directory with their names, timestamps, filesizes etc as individual fields? Doing the "ls" outputs to the console the list but I can't access the string of the output nor do I see how I can get a list of files like in a to access them? I'm using C++ (with GCC under Linux and VisualStudio under Windows) and saw that these class-files are different per compiler vendor but both incomplete with regards to the C interface:

• tgputtylibcbclass
• tgputtylibvcclass

When I transfer files, they seem to have random permissions, e.g.:

[email protected]:~$ ls -la README.md 
---------- 1 user user 2053 Dez  3 09:28 README.md

Server umask is 0002. I observed other (sometimes quite strange) permissions as well. As a workaround, I read the stats of the target directory and assign the permissions to the transferred file. It seems to be quite awkward to having to do it this way:

sftp.GetStat('.', Attrs);
sftp.UploadFile(MyFile, False);
sftp.GetStat(MyFile, AttrsUpload);
AttrsUpload.permissions := Attrs.permissions;
sftp.SetStat(MyFile, AttrsUpload);

Is there a better way to achieve proper permissions of the uploaded files?

Get this error when compiling it with XE$ for the first time: [dcc32 Error] tgputtysftp.pas(494): E2034 Too many actual parameters at: attrs.mtime:=DateTimeToUnix(ATimestamp,isUTC);

I guess it's just a very small issue and I'll fix it when I started using it some time later if you don't , but just report it here first :)

Happy holidays :)

I'm running D10.2 and copied the file tree to a folder, built the libs and component and installed the component.

I tried to open the VCL component demo and it gave a weird "External Exception C06D007E" while opening the form, and didn't load the component properly.

So I opened the VCL non-component demo and it builds and runs just fine.

I copied the code to init everything from this running app into my app. It compiles fine, but it blows up when it get to initializing the DLL. Same error as the component (different address).

I don't work with DLLs very much, and this just seems to be throwing an unhandled exception. I'm not sure what to do to make it work, or why the one demo would work fine and my code that's doing the exact same stuff would blow up.

Is there supposed to be a delay in opening the DLL so it can get the OnVerifyHostKey callback configured? Because it's blowing up on the initial Create with no opportunity to set the callback.

It's blowing up here:

constructor TTGPuttySFTP.Create(const verbose:Boolean);
var puttyversion:Double;
    tgputtylibbuild:Integer;
begin
  tgputtygetversions(@puttyversion,@tgputtylibbuild);    <<-----------------

So I started evaluating and choosing a sFTP client.

I'm testing it against a FreeSSHd SFTP server on local Windows, and an OpenSSH server also on Windows.

• I first tried https://github.com/pult/libssh2_delphi, it can connect to OpenSSH, and failed to connect to FreeSSHd (returns some thing like 'waiting for password response' which I couldn't figure out how to fix).

• Then I tried SecureBridge (not the latest version, I don't have it. It's an old version released about 2 years ago). It failed to connect to the local FreeSSHd server (I foroget the error message), so I stopped testing it further.

• At last I tested TGputtyLib, and it can connect to both of the servers! I'm testing it further now...

Hi, there is any way to connect to a SFTP server with a private key(without using a password)?. I only have a ppk file and i don't have the password.

When I use the latest Windows (under Windows10) GUI app (Build13) and replace the lib with the latest binary (Build16) then I receive the following error each time, while I can connect to that ftp server fine with CyberDuck. It gave the same error using lib version Build13 btw. This is the log:

Hello Tobias,

When I get errors like:

TGPuttySFTPException: tgsftp_cd: Error 5, bad message

Where I can find a list of such errors along with the explanations of the errors?

PS, from the log of the FreeSSHd the error is that the directory the client want to change to doesn't exist.

Thanks!

This is definitely a useful project! Just out of curiosity - why don't use libssh directly? From the homepage I read that the advantage of TGPuttyLib is faster transfer speed?

I've no experience with libssh nor TGPuttyLib yet, but will need to implement sFTP transfer function in the near future, so will be happy to hear about how do you think. Because I guess using libssh needs less work if libssh satisfied you at the very beginning.

And happy holidays!

From time to time, updating local repository fails no matter it's TortoiseSVN or GitExtension, using direction connection or going through Socks5 proxy. I guess it maybe because there a quite amount of the big EXE files in the repo.

Would you consider separate those DEMO EXEs out of the source repository?

Thanks for your consideration.

Hi, thanks for the great software. I'm trying to add gputtylib.pas and gputtysftp.pas to a C++ Builder project. I can usually mix PAS and CPP with no problem, but I am getting an unresolved external for each procedure in gputtylib.pas that declared to be in the DLL. here's an example.

procedure tggetstructsizes(const Pulongsize,Pnamesize,Pattrsize,Pnamessize:PInteger); cdecl; external tgputtydll {$ifdef HASDELAYED}delayed{$endif};

I can use the PAS files in a Delphi program with no problem. Any ideas what I can do to keep the linker in C++Builder happy.

As an aside, I have made a C++ project using the C++ specific files, but it crashes when downloading a file from an SFTP server. This is why I'd like to use the PAS files, as they work perfectly in a Delphi app.

It would be helpful to have an example of a generic C++ use of strings with STL that can run under Windows and Linux. The examples now are very specific to compiler vendors only, I don't see this as an advantage, especially for a C++ user. Also I find the mislabelling of C code as "C++" not appropriate.

The progress information during download (OnProgress event) is driven due to

if Assigned(TGPSFTP.OnProgress) then
 TGPSFTP.OnProgress(Offset+bufsize,false);

In write_to_stream(), is there a reason the same code is not in read_from_stream() to give equal progress during upload? Like this:

function read_from_stream(const offset:UInt64;const buffer:Pointer;const bufsize:Integer;const libctx:PTGLibraryContext):Integer; cdecl;
var TGPSFTP:TTGPuttySFTP;
begin
  TGPSFTP:=TTGPuttySFTP(libctx.Tag);
  if Assigned(TGPSFTP.FUploadStream) then begin
     TGPSFTP.FUploadStream.Position:=Offset;
     Result:=TGPSFTP.FUploadStream.Read(buffer^,bufsize);
     if Assigned(TGPSFTP.OnProgress) then
        TGPSFTP.OnProgress(Offset+bufsize,false);
     end
  else
     Result:=0;
  end;
