I have installed Mulval successfully.
The problem is : I have not get the AttackGraph.pdf by using the coding "graph_gen.sh /root/data/mulval/testcases/3host/input.P -v".
May I know,
system give the tip: render.sh: epstopdf : have not find the order.
the reason is : the "eps" file have not translated the "pdf" file.
Because i use the centos7 , not the Ubantu, Maybe system need the transfor tool.

I need to create ECDSA keys and used old OpenSSL code until now, which dosn't compile any more under OpenSSL3, there are now lots of deprecation errors. I invested now several days with search & try, but I can't solve it. I am trying the simple example [https://fm4dd.com/openssl/eckeycreate.shtm][1], but already the first lines create these errors:
WorkerThread.cpp(34,2): error C4996: 'ERR_load_BIO_strings': Since OpenSSL 3.0
WorkerThread.cpp(47,19): error C4996: 'EC_KEY_new_by_curve_name': Since OpenSSL 3.0
WorkerThread.cpp(54,2): error C4996: 'EC_KEY_free': Since OpenSSL 3.0
So the first idea would be to eliminate these compiler errors somehow. I found the switches
#define OPENSSL_API_COMPAT 30000
#define OPENSSL_NO_DEPRECATED
but they create even more errors, because now suddenly even the EC_KEY is unknown to the compiler. No solution.
So there stays the hard way to try to migrate the code somehow to OpenSSL3, because there seems to be no example code in the whole internet for simply creating an ECDSA key with OpenSSL3, and extract the private and public part. But just changing single functions with an OpenSSL3 matching function doesn't solve it, because the whole concept changes (switching from low level API to high level, with a completely different programming model).
I have tried fiddling around with lots of examples, but it looks like my programming task that seems so simple is a very complicated thing. Any help is appreciated, but I want to stay in C/C++ because my application is performance critical.
Environment: MS Win10, MS Visual Studio 2019, latest OpenSSL 3
[1]: https://fm4dd.com/openssl/eckeycreate.shtm
WorkerThread.cpp(34,2): error C4996: 'ERR_load_BIO_strings': Since OpenSSL 3.0
You don't need to call any of those initialisation functions. Just remove them from your code. They are not needed with any version of OpenSSL from 1.1.0 onwards.
In the example, all of the code for getting an EC_GROUP, creating an EC_KEY, generating a key, setting the OPENSSL_EC_NAMED_CURVE flag and assigning it to an EVP_PKEY can be completely removed. Replace it with a simple call to EVP_EC_gen(). See the man page here:
https://www.openssl.org/docs/man3.0/man3/EVP_EC_gen.html
E.g. all of that code can be replaced with something like
pkey = EVP_EC_gen("secp521r1");
if (pkey == NULL) {
BIO_printf(outbio, "Error generating the ECC key.");
abort();
}
I am running libsvm through weka. Its output accuracy looks good to me, so I am planning to write a svm model by myself. However, weka didn't generate any training parameter, such as number of support vector. Therefore i cannot do anything. Searching the web, i found somebody said it would generate some parameters like the following:
optimization finished, #iter = 27
nu = 0.058475864943863545
obj = -1.871013102744184, rho = -0.19357337828800944
nSV = 9, nBSV = 0 `enter code here`
Total nSV = 9
but how come i didn't see any of them? any step that i missed? please help me. Thanks a lot.
Weka writes the output you mentioned to stderr.
So if you have started weka.sh or weka.bat from a terminal (or "command window" if you are on Windows), you should see that output appear in your terminal window after clicking "classify"
If you want to have access to this information via scripts, you can
redirect the output to a file and read in that file.
Here is how to edit the startup file weka.sh / weka.bat.
Edit this line (it is probably the last line) in order to write log info to a file instead of the terminal window:
java -cp $CP -Xmx8092m weka.gui.GUIChooser 2>>/opt/weka-stable/weka.log &
You can also add a properties file to your home directory to add more fine-grained behaviour.
https://weka.wikispaces.com/Properties+file
(You probably can also access information via the Weka Java API somehow, but you did not ask for that)
So I have a software program that for reasons that are beyond this post, I will not include but to put it simply, I'd like to "MOD" the original software. The program is launched from a Windows Application named ViaNet.exe with accompanying DLL files such as ViaNetDll.dll. The Application is given an argument such as ./Statup.cat. There is also a WatchDog process that uses the argument ./App.cat instead of the former.
I was able to locate a log file buried in my Windows/Temp folder for the ViaNet.exe Application. Looking at the log it identifies files such as:
./Utility/base32.atc:_Encode32 line 67
./Utilities.atc:MemFun_:Invoke line 347
./Utilities.atc:_ForEachProperty line 380
./Cluster/ClusterManager.atc:ClusterManager:GetClusterUpdates line 1286
./Cluster/ClusterManager.atc:ClusterManager:StopSync line 505
./Cluster/ClusterManager.atc:ConfigSynchronizer:Update line 1824
Going to those file locations reveal files by those names, but not ending with .atc but instead .cat. The log also indicates some sort of Class, Method and Line # but .cat files are in binary form.
Searching the program folder for any files with the extension .atc reveals three -- What I can assume are uncompiled .cat files -- files. Low and behold, once opened it's obviously some sort of source code -- with copyright headers, lol.
global ConfigFolder, WriteConfigFile, App, ReadConfigFile, CreateAssocArray;
local mgrs = null;
local email = CreateAssocArray( null);
local publicConfig = ReadConfigFile( App.configPath + "\\publicConfig.dat" );
if ( publicConfig != null )
{
mgrs = publicConfig.cluster.shared.clusterGroup[1].managers[1];
local emailInfo = publicConfig.cluster.shared.emailServer;
if (emailInfo != null)
{
if (emailInfo.serverName != "")
{
email.serverName = emailInfo.serverName;
}
if (emailInfo.serverEmailAddress != "")
{
email.serverEmailAddress = emailInfo.serverEmailAddress;
}
if (emailInfo.adminEmailAddress != null)
{
email.adminEmailAddress = emailInfo.adminEmailAddress;
}
}
}
if (mgrs != null)
{
WriteConfigFile( ConfigFolder + "ZoneInfo.dat", mgrs);
}
WriteConfigFile( ConfigFolder + "EmailInfo.dat", email);
So to end this as simply as possible, I'm trying to find out two things. #1 What Programming Language is this? and #2 Can the .cat be decompiled back to .atc. files? -- and vice versa. Looking at the log it would appear that the Application is decoding/decompiling the .cat files already to interpret them verses running them as bytecode/natively. Searching for .atc on Google results in AutoCAD. But looking at the results, shows it to be some sort of palette files, nothing source code related.
It would seem to me that if I can program in this unknown language, let alone, decompile the existing stuff, I might get lucky with modding the software. Thanks in advance for any help and I really really hope someone has an answer for me.
EDIT
So huge news people, I've made quite an interesting discovery. I downloaded a patch from the vendor, it contained a batch file that was executing ViaNet.exe Execute [Patch Script].atc. I quickly discovered that you can use Execute to run both .atc and .cat files equally, same as with no argument. Once knowing this I assumed that there must be various arguments you can try, well after a random stroke of luck, there is one. That being Compile [Script].atc. This argument will compile also any .atc file to .cat. I've compiled the above script for comparison: http://pastebin.com/rg2YM8Q9
So I guess the goal now is to determine if it's possible to decompile said script. So I took a step further and was successful at obtaining C++ pseudo code from the ViaNet.exe and ViaNetDll.dll binaries, this has shed tons of understanding on the proprietary language and it's API they use. From what I can tell each execution is decompiled first then ran thru the interpreter. They also have nicknamed their language ATCL, still no idea what it stands for. While searching the API, I found several debug methods with names like ExecuteFile, ExecuteString, CompileFile, CompileString, InspectFunction and finally DumpObjCode. With the DumpObjCode method I'm able to perform some sort of dump of script files. Dump file for above script: http://pastebin.com/PuCCVMPf
I hope someone can help me find a pattern with the progress I made. I'm trying my best to go over the pseudo code but I don't know C++, so I'm having a really hard time understanding the code. I've tried to seperate what I can identify as being the compile script subroutines but I'm not certain: http://pastebin.com/pwfFCDQa
If someone can give me an idea of what this code snippet is doing and if it looks like I'm on the right path, I'd appreciate it. Thank you in advanced.
I am new to c++ programming , today i was trying to save an image using CImg .
CImg is C++ Template Image Processing Library .
The basic code i wrote is(Please forgive any syntax erros , as copied part of my codes) :
#include "CImg.h"// Include CImg library header.
#include <iostream>
using namespace cimg_library;
using namespace std;
const int screen_size = 800;
//-------------------------------------------------------------------------------
// Main procedure
//-------------------------------------------------------------------------------
int main()
{
CImg<unsigned char> img(screen_size,screen_size,1,3,20);
CImgDisplay disp(img, "CImg Tutorial");
//Some drawing using img.draw_circle( 10, 10, 60, RED);
img.save("result.jpg"); // save the image
return 0;
}
But I cannot run my program as it says :
Invalid Parameter - 100%
'gm.exe' is not recognized as an internal or external command,
operable program or batch file.
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
[CImg] *** CImgIOException *** [instance(800,800,1,3,02150020,non-shared)] CImg<unsigned char>::save_other() : Failed to save file 'result.jpg'. Format is not natively supported, and no external commands succeeded.
terminate called after throwing an instance of 'cimg_library::CImgIOException'
what(): [instance(800,800,1,3,02150020,non-shared)] CImg<unsigned char>::save_other() : Failed to save file 'result.jpg'. Format is not natively supported, and no external commands succeeded.
Though i can see the image , I cannot save it.
After googling a bit i found people saying to install ImageMagick , i have installed it but no help .
Some of the Forum says to compile against libjpeg, libpng, libmagick++. But i don't know how to compile against those libraries.
I am using Eclipse CDT plugin to write C++ project .
Please help me .
I had the same error, and installing of GraphicsMagick (not ImageMagick) helped me.
I've downloaded and installed GraphicsMagick-1.3.26-Q8-win64-dll.exe from ftp://ftp.graphicsmagick.org/pub/GraphicsMagick/windows/. You may choose another one, if you need:
Note that the QuantumDepth=8 version (Q8) which provides industry
standard 24/32 bit pixels consumes half the memory and about 30% less
CPU than the QuantumDepth=16 version (Q16) which provides 48/64 bit
pixels for high-resolution color. A Q8 version is fine for processing
typical photos intended for viewing on a computer screen. If you are
dealing with film, scientific, or medical images, use ICC color
profiles, or deal with images that have limited contrast, then the Q16
version is recommended.
Important: during installation, don't remove checkbox "Update executable search path", which updates environment variable %PATH%, making gm.exe available from any place.
In my case, it was also required to install Ghostscript - which is highly recommended to install by GraphicsMagick. There is a link to x64 Ghostscript: https://sourceforge.net/projects/ghostscript/files/GPL%20Ghostscript/9.09/gs909w64.exe/download (I've put it here, because links from the GraphicMagick websites leads you to 32-bit only).
After that, it worked fine for me.
For some image formats (as .jpg, .png, .tif and basically all formats that require data compression), CImg will try to use an external tool to save them (such as convert from ImageMagick or gm from GraphicsMagick).
If you don't have any installed, then you won't be able to save .jpg files without having to link your code with the libjpeg library, to get a native support for JPEG read/write (then, you'll need to #define cimg_use_jpeg before #include "CImg.h", to tell the library you want to use the libjpeg features).
If you want to keep things simpler, I'd recommend to save your image using another (non-compressed) image format, as .bmp or .ppm.
These formats are handled natively by CImg and do not require to link with external libraries.
I know this question is old, but I kept getting the same error on one project and not on another and this is the only thing on Google.
To get rid of it, you must do 2 things:
Install dynamic ImageMagick libraries for your appropriate OS and architecture(32/64). Link
I was using VisualStudio, and the character set must be set to "Unicode". The error would appear again when I reverted back to Multi-Byte character set. I guess this has something to do with the way CImg handles strings and miscompares them.
Good Day,
I have searched the Internet tirelessly trying to find an example of how to start Windows Speech Training from with in my VB.Net Speech Recognition Application.
I have found a couple examples, which I can not get working to save my life.
One such example is on the Visual Studios Fourms:
HERE
this particular example users the "Process.Start" call to try and start the Speech Training Session. However this does not work for me. Here is the exmaple from that thread:
Process.Start("rundll32.exe", "C:\Windows\system32\speech\speechux\SpeechUX.dll, RunWizard UserTraining")
What happens is I get and error that says:
There was a problem starting
C:\Windows\system32\speech\speechux\SpeechUX.dll
The specified module could not be found
So I tried creating a shortcut (.lnk) file and thought I could access the DLL this way. My short cut kind of does the same thing. In the short cut I call the "rundll32.exe" with parameters:
C:\Windows\System32\rundll32.exe "C:\Windows\system32\speech\speechux\SpeechUX.dll" RunWizard UserTraining
Then in my VB.Net application I use the "Process.Start" and try to run the shortcut.
This also gives me the same error. However the shortcut itself will start the SPeech Training session. Weird?!?
So, I then took it one step further, to see if it has something to do with my VB.Net Application and the "Process.Start" Call.
I created a VBScript, and using "Wscript.Shell" I point to the Shortcut.
Running the VBScript calls the Shortcut and low and behold the Speech Training starts!
Great! But...
when I try to run the VBscript from my VB.net Application, I get that error again.
What the heck is going on here?
Your problem likely is that your program is compiled as 32-bit and your OS is 64-bit, and thus, when you try to access "C:\Windows\System32\Speech\SpeechUX\SpeechUX.dll" from your program, you're really accessing "C:\Windows\SysWOW64\Speech\SpeechUX\SpeechUX.dll" which, as rundll32.exe is reporting doesn't exist.
Compile your program as 64-bit instead or try the pseudo directory %SystemRoot%\sysnative.
Also, instead of rundll32.exe, you may want to just run SpeechUXWiz.exe with an argument.
Eg.
private Process StartSpeechMicrophoneTraining()
{
Process process = new Process();
process.StartInfo.FileName = System.IO.Path.Combine(Environment.SystemDirectory, "speech\\speechux\\SpeechUXWiz.exe");
process.StartInfo.Arguments = "MicTraining";
process.Start();
return process;
}
private Process StartSpeechUserTraining()
{
Process process = new Process();
process.StartInfo.FileName = System.IO.Path.Combine(Environment.SystemDirectory, "speech\\speechux\\SpeechUXWiz.exe");
process.StartInfo.Arguments = "UserTraining";
process.Start();
return process;
}
Hope that helps.
Read more about Windows 32-bit on Windows 64-bit at http://en.wikipedia.org/wiki/WoW64
or your problem specifically at http://en.wikipedia.org/wiki/WoW64#Registry_and_file_system
If you are using a 64bit OS and want to access system32 folder you must use the directory alias name, which is "sysnative".
"C:\windows\sysnative" will allow you access to system32 folder and all it's contents.
Honestly, who decided this at Microsoft is just silly!!
