I like to use Scapy with Python v2.7 under Windows 7.
How can I install the required module pypcap for Python 2.7?
Will it be possible to make Python scripts depending on Scapy into standalone Windows applications using a distribution tool such as py2exe?
The particular Python distribution I am using is Enthought Python distribution 7.02.
Intrusive update: please note that this answer is outdated, with recent versions (>=2.4.0) scapy will ONLY require Npcap (or Winpcap) to work, and IPython for the console. Have a look at the official windows page
In case someone needs Scapy for 64-bit + Python 2.7, I've uploaded the binaries here:
https://github.com/Kondziowy/scapy_win64
dnet-1.12.win-amd64-py2.7.exe
pcap-1.1.win-amd64-py2.7.exe
scapy-2.2.0.win-amd64.exe
In addition, you probably need to install WinPcap from the official site
Compiling it yourself required a few fixes - I'll commit them upstream soon.
Q: how can i install required module pypcap
Using Scapy with Windows 7 is possible, but it does not exactly work out of the box. An install guide can be found here:
http://www.secdev.org/projects/scapy/doc/installation.html#windows
I strongly recommend to switch to python 2.6, as this will make your live much easier.
When you insist on 2.7 you will have to compile some of the require modules yourself. Also, some key modules like pypcap have to be patched before they can be compiled with python 2.7 (see pycap patch).
Here you will find some guidance on how to build the modules.
Q: will it be possible to make python scripts depending on scapy into standalone windows applications
Yes and no. While you can use py2exe to build a an EXE from your python code. Scapy uses WinPcap which you have to install in addition to your application.
Dirk Loss provides an Windows installer for the dnet package for Python 2.7. Together with the Windows installer for the pypcap package for Python 2.7 I was able to run Scapy successfully on Python 2.7 on Windows.
A LOT OF ANSWERS ARE OUTDATED !
Latest scapy version, that you can download on the official GitHub page:
https://github.com/secdev/scapy
Works without the old hand-compiled dependencies!
They are two easy requirements: IPython (for the console) and npcap (or winpcap)
You may follow the official tutorial here:
http://scapy.readthedocs.io/en/latest/installation.html#windows
Using the link posted by circus, I created binary installations for Scapy for python 2.7.x 32bit. Link for the setups (with dependencies) https://github.com/Kondziowy/scapy_win64
If you don't have limitations forcing you to work with python2, you can try scapy3k from http://github.com/phaethon/scapy or pip install scapy-python3.
It does not require dnet nor pypcap, no C compilation required. I work with following config Windows 10/Anaconda 3.5/latest WinPcap.
Minimum requirement to get Scapy running on Windows with Python 2.7 seems to be: pyreadline, pcapy, and dnet. The last two are the trickiest to compile and/or find pre-compiled binaries. One option for these is listed in the above answer. Another download, together with with detailed steps on how getting Scapy to run on Windows is at: https://github.com/zlorb/scapy. These steps describe also how to get the optional dependencies, such as Gnuplot and Tex.

We used to distribute (for Windows) a very large Python 2/PyGTK application by packaging Python installer itself along other needed installers and packages through an InnoSetup script. Among with those other installers and packages we deliver an all-in-one PyGTK package and it worked very well.
Now we've converted our software for Python 3 and GTK 3. Ok, there is an all-in-one for PyGI [1] (PyGObject Introspection), but just for Python 2.7 to 3.4 and we need at least Python 3.7.
I've spent last couple of weeks learning MSYS2 and trying to understand how MyPaint or Gaphor (which are similar apps) are distributed for Windows without success. I am able to download and install GTK and PyGI using pacman on MSYS2/MingW64 but I cannot figure out how can I create such a package like PyGI all-in-one. I asked for help or instructions on SourceForge but I got no responses so far.
I am asking for help or any clues on how can I generate a PyGI-all-in-one-like installer. Thanks in advance!

You can bundle a PyGObject app in Windows using PyInstaller. It can be used with either MSYS2 or gvsbuild to find and bundle all the GTK libraries you need. Then you can use your InnoSetup script to create an installer.
I am not a regular Linux user so this might be completely trivial question. I am running 6.2 PUIAS version i386_64 on one of my GPU based "super" computers due to the unavailability of NVidia drivers for NetBSD. The installed version of Python is 2.6.6. I need 2.7.2 Python and newer version of scipy, numpy, matlibplot and friends. I have PUIAS and EPEL repositories enabled. However they do not have newer versions of Python. What is the "recommended" way to install newer version of Python without braking the system which depends on it. I am not interested in Python 3.2 due to the lack of libraries for scientific computing.
When the install-Python-from-source routine tells you to use make install, type make altinstall instead. This will leave the normal python executable untouched and instead create python2.7 for you to use. Install the other packages from source using this new executable. Don't forget to change the shebang line in your scripts accordingly.
I am going to answer my own question. For people who are using Python for scientific computing on RedHat clones (PUIAS for example) the easiest way to get all they need is to use rpm package manager and Enthought Python Distribution (EPD for short). EPD installs everything in a sandbox so system tools which are based on an obsolete version of Python are not massed up. However, paths have to be adjusted for system or even easier on the user base so that the using shell invokes non-system tools. One should never compile Python from source unless you are interesting in Python itself or in porting it to your favorite operating system rather than in your own research!
I have Python2.6.5 and Python2.4.4 on my linux machine.
At the moment, all the modules I have (wx, ply, pyserial, twisted, to name a few) are installed for the 2.6 version of python. If I try to import wx on Python2.4, I get the expected no module error.
The problem here, is that I have a lot of devices (Let's say over a thousand) all running 2.4.4, which will soon need to be supported by this machine (For builds of code, releases etc). Until now, I've been using an EeePC (Same device as the ones I'm supporting) to do builds and releases, which has worked well. (I develop on the 2.6 machine, and build on the EeePC).
How would I go about getting these modules to work for Python2.4? I've tried reinstalling (With 2.4 as my primary), but that just caused errors. The blogs/answers I've found say to use easy_install, but that doesn't support the packages I need (Or at least, it just died when I tried).
In short: I'm currently using python 2,6, but I'd like it to change to 2.4 for all the modules as that's what I'm going to be using.
You can't share modules between different versions of Python. If you want to use wxPython from Python 2.4, you need to install it for Python 2.4.
You said you tried to install it with Python 2.4 as your "primary". I'm not sure what that means. You would install wxPython for Python 2.4 by running the installer with Python 2.4, like so:
$sudo /usr/bin/python2.4 setup.py install
Or similar.
You can use easy_install as well, but then you need to install Distribute for Python 2.4 first. Did you do that?
I recently wrote a full explanation on my blog about this: http://regebro.wordpress.com/2011/02/02/newbie-hint-on-installing-python-and-its-modules-and-packages/
Don't attempt to share them; this has some chance of success with pure Python modules, but C modules will fail to work. Instead, install them using the appropriate interpreter executable, e.g. python2.4 setup.py install.
I have Mercurial 1.3 installed on my Windows 7 machine. I don't have python installed, but Mercurial seems to be OK with that.
How does it work?
Also, is it possible to force Mercurial run on IronPython and will it be compatible?
Thank you.
The Mercurial windows installer is packaged using py2exe. This places the python interpreter as a DLL inside of a file called "library.zip".
On my machine, it is placed in "C:\Program Files\TortoiseHg\library.zip"
This zip file also contains the python libraries that are required by mercurial.
For a detailed description of how mercurial is packaged for windows, see the developer page describing building windows installer.
Since there is a "library.zip"(9MB), Mercurial's Windows binary package maybe made by py2exe, py2exe is a Python Distutils extension which converts Python scripts into executable Windows programs, able to run without requiring a Python installation.
Others have answered the first question -- let me give a guess about the second part.
Mercurial will normally use some C extensions for speed. You cannot use those with IronPython.
But we also ship pure Python versions of these modules, and depending on how much IronPython implements of a standard Python 2.4 environment, those modules could be compatible. I have seen reports on IRC about Jython (the Java port of Python) being able to do a few operations using the pure modules. You should download Mercurial and take a look at the mercurial/pure folder. These modules simply has to be moved up one directory level to be found, the setup.py script can do this if you pass the --pure flag. Please see its source or come talk with us on the Mercurial mailinglist/IRC.
Mercurial bundles the necessary python binaries within it, I believe.
I have a linux VPS that uses an older version of python (2.4.3). This version doesn't include the UUID module, but I need it for a project. My options are to upgrade to python2.6 or find a way to make uuid work with the older version. I am a complete linux newbie. I don't know how to upgrade python safely or how I could get the UUID modules working with the already installed version. What is a better option and how would I go about doing it?
The safest way to upgrading Python is to install it to a different location (away from the default system path).
To do this, download the source of python and do a
./configure --prefix=/opt
(Assuming you want to install it to /opt which is where most install non system dependant stuff to)
The reason why I say this is because some other system libraries may depend on the current version of python.
Another reason is that as you are doing your own custom development, it is much better to have control over what version of the libraries (or interpreters) you are using rather than have a operating system patch break something that was working before. A controlled upgrade is better than having the application break on you all of a sudden.
The UUID module exists as a separate package for Python 2.3 and up:
http://pypi.python.org/pypi/uuid/1.30
So you can either install that in your Python2.4, or install Python2.6. If your distro doesn't have it, then Python is quite simple to compile from source. Look through the requirements to make sure all the libraries you need/want are installed before compiling Python. That's it.
The best solution will be installing python2.6 in the choosen directory - It will you give you access to many great features and better memory handling (infamous python=2.4 memory leak problem).
I have got several pythons installed onto my two computers, I found that the best solution for are two directories:
$HOME/usr-32
$HOME/usr-64
respectively to using operating system (I share $HOME between 32 and 64 bit versions of Linux).
In each I have one directory for every application/program, for example:
ls ~/usr-64/python-2.6.2/
bin include lib share
It leads completetely to avoiding conflicts between version and gives great portability (you can use usb pendrives etc).
Python 2.6.2 in previously example has been installed with option:
./configure --prefix=$HOME/usr-64/python-2.6.2
