      @Timo Ok then… apologies, it wasn’t totally clear to me. I’m informing @Jbob about it to see what he says then.

      Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

        Redirecting ping to @Tom-Elliott, this is most likely a server issue.

          This translates to “value of Content-Length header is invalid”! Possibly .Net does not like such a big value??

          Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

            Good Morning, this MOrning i’ve updated to latest GIT 7242. Now when i try to download the Snapin via Basic Task “Single Snapin” it comes up in the Log with " Unable to hash file, The file is too long. This process currently only supports files with a size of less than 2 GB.

            So i think at this time it is not possible… 😞 !!!

              Is it possible to increase that? If so, where i can change that value?

                @Timo Can you simply try updating? I removed the Content-Length setter in hopes that is all it takes to fix the issue at hand.

                          @Timo This seems to be a restriction in C# following the discussion here: http://www.codeproject.com/Questions/142532/appending-and-splitting-files-larger-than-gb

                          Possibly this is only happening because you have 32 bit Windows installed?? Please check! Or this might be a general restriction and we need to read large snapin files as chunks, @Jbob?

                              @Timo the original header problem is fixed. @Sebastian-Roth is correct in that the hashing error is a limitation of c#. I’ll see what I can do.

                                @Timo for now you could set the snapin file to a batch script which downloads the exe from a samaba share or something and runs it.

                                  Hi Jbob thx for your help. How can i realize that? I’ve an Synology NAS where i can store that, do you have an example script, maybe?

                                    @Timo Batch lacks the ability to download a file natively. Here is a vbs script which should do what you are looking for.

                                    Save the code as “Bootstrap.vbs”, and update the http://fog-server/MyProgram.exe line to reflect a real URL where your snapin can be downloaded, the easiest way may be to just copy your snapin file to /var/www/html/, and then it is accessible via http://{fog-server}/MyProgram.exe, where Myprogram.exe is the file name. Also update references to MyProgram.exe to your program’s file name.

                                    Note that this code is untested.

                                    Use the following snapin settings:
                                    Snapin Run With: cscript
                                    Snapin Run With Args: //B //Nologo
                                    Snapin File: Bootstrap.vbs

                                    Bootstrap.vbs code:

                                      I’d opt for a batch file still as a stop-gap.

                                      use xcopy to get the file. it supports UNC paths.

                                        @Jbob said in FOG Snapin Client download error:

                                        @Timo Batch lacks the ability to download a file natively. Here is a vbs script which should do what you are looking for.

                                        Save the code as “Bootstrap.vbs”, and update the http://fog-server/MyProgram.exe line to reflect a real URL where your snapin can be downloaded, the easiest way may be to just copy your snapin file to /var/www/html/, and then it is accessible via http://{fog-server}/MyProgram.exe, where Myprogram.exe is the file name. Also update references to MyProgram.exe to your program’s file name.

                                        Note that this code is untested.

                                        Use the following snapin settings:
                                        Snapin Run With: cscript
                                        Snapin Run With Args: //B //Nologo
                                        Snapin File: Bootstrap.vbs

                                        Bootstrap.vbs code:

                                            @Timo memory is not disk space. It sounds, to me, like it’s trying to put the whole file in ram. You may need to have the script copy the file locally then run it from the local machine.
