I'm trying to run an executable using pwntools using a different version of libc than the one I installed locally. Is there any way I can do that?
I tried this way, but it doesn't seem to work.
I will attach a picture with the script and also with what error I got.
io = process(BIN, env={"LD_PRELOAD": "./libc.so.6"})
I am running this on Ubuntu 20.04 using python 3.8.

im trying to make v4l2loopback work on my desktop PC (no hardware camera) with mint 19.3, kernel 5.4.0-42-generic x86_64.
I followed the official instructions and compiled from git the v4l2loopback module and everything seem to run correctly, as no error prompted while running the instructions, but when i do ll /dev/v* there's no /dev/videoN entry.
I also tried with the flags exclusive_caps=1 and devices=2 but to no avail.
Any idea what i might be missing or doing wrong?
you need to load the module (e.g. using modprobe) before you can use it.

I am using cygwin on window.
and Running follows command on cygwin for starting ksql server.
bash ksql-server-start .properties
Error: Could not find or load main class Folder.confluent-5.5.1-2.12.tar.confluent-5.5.1-2.12.confluent-5.5.1.logs
Thanks.
No Windows compatible scripts are provided with ksqlDB. You may be able to 'fix' the scripts that do come with it to work on windows. Alternatively, you can just run ksqlDB and the CLI in docker, which is the supported routed for Microsoft windows. See the ksqlDB microsite for instructions on how to get something up and running in docker, or the Kafka examples microsite.
This one may be for the experts!
So here is the problem:
I have a flask app that gets its data from Postgresql and it runs fine in my normal environment. I tried to deploy it locally using virtualenv and after pip installing all the requirements the only one that gave me trouble is psycopg2 which appears to be dependency of Postgresql.
I then used this amazing article to help me install it, by putting export PATH=/Library/PostgreSQL/9.3/bin:$PATH to the .bash_profile file.
But now I get this error:
Library not loaded: libssl.1.0.0.dylib ...Image not found
What is going on?
My final goal is to use Python scripts with SciPy, NumPy, Theano and openCV libraries to write code for a machine learning application. Everything worked so far apart from the openCV.
I am trying to install openCV 2.4.8 to use in Python projects in my Eclipse Kepler installation on my MBA running Mac OSX 10.9.2. I have the PyDef plugin v2.7 and a installation of Anaconda v1.9.1.
Here is what I did to install opencv:
sudo port selfupdate
sudo port upgrade outdated
sudo port install opencv
Then I realized that I can't use it that way in Python and did another:
sudo port install opencv +python27
Ok, then I had another Python installation and I added it to my PYTHONPATH in Eclipse>Preferences>PyDev>Interpreter-Python>Libraries.
Before the installation I got an error in the line import cv2, and everything else looked promising. Now this error disappeared but I get other errors when using any functions or variables of cv2. For example I get two errors in this line: cv2.cvtColor(image, cv2.COLOR_RGB2BGR)
Also Python crashes and has to be restarted when I run a simple test program which worked fine before.
With this PYTHONPATH everything works but I have no openCV:
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages
/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload
/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pyObjC
/Library/Python/2.7/site-packages/
/Users/xxx/anaconda/lib/python2.7/site-packages
When I add this new folder to the PYTHONPATH...
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages
... openCV seems to work but I have the crashes and the other issue described above.
So, can anyone tell me what the problem is and what I can do to make this work?
Thanks for reading this so far and any help/hint you can provide! Please don't be too harsh, I am, as you can probably easily see just a beginner.
Ok, it's working now. Here is what I did:
Install Python and every package I need for it with Macports
Set the Macports version as standard
Adjust PATH and PYTHONPATH
Reboot (not sure if needed)
Remove old interpreter and libs in Eclipse
Choose the new Python installation as Interpreter in Eclipse
Confirm the new libs in Eclipse
Restart Eclipse
Done
I've been learning python for some time now. Recently I needed to install in my Mac the Image module for Python, and after a while I achieve this running a mpkg installer specially for my OS, so far everything was ok and I could run my script.
Now I'm in the needing of running my script in my jailbroken iPhone, which already has a python interpreter, and I need to install this Image module again but this time on my phone.
Is there another way to do it? How can I do it manually?
I found out how
I downloaded the PIL 1.1.7 source from http://www.pythonware.com/products/pil/ and untared the Imaging-1.1.7.tar.gz file, then I made the following commands:
cd Imaging-1.1.7/
python setup.py install
You can also follow the instructions on the README file in Imaging-1.1.7/ for building the package on your own.
that's it
