How can I install Scapy?

Webmaster4o

Fixed ;) Those were my math grades :)

You script didn't work for me. This one did however and basically works as the open in replacement :)

Does Scapy actually run under Pythonista?

Webmaster4o

@ihf yes, it imports without error.

Webmaster4o

@miwagner1 I updated it, that might fix your issue?

miwagner1

Ya fixing the path to have Pythonista generate, os.path.expanduser did it. now lets hope apple won't make him pull the extension as its letting me do all sorts of cool stuff.

ihf

Just for fun, I downloaded scapy 2.3.1, unzipped it, and moved it to site-packages. If I then try to run main.py, I get errors in console regarding IPv6 support disabled in Python. That's probably OK but then the program stops at line 278 with NameError:name 'LOOPBACK_NAME' is not defined. How did you get this to run?

Webmaster4o

I didn't actually test it, I just imported. Import worked for me, though.

inzel

I am getting the same NameError:name 'LOOPBACK_NAME' is not defined error that @ihf came across a year ago. Does anyone know how to get around that? I would really like to be able to use scapy. Thanks!

abcabc

Look at this link. I have not tried it.
https://github.com/secdev/scapy/issues/401

inzel

I came across this before but didnt make test the change because Im on an iPad running stash. Ill give it a shot and see what happens. Thanks!

inzel

I added this to the ../windows/__init.py__ file and there was no change. I then added it to the __init.py__ file in the arch folder and that changed the error from LOOPBACK_NAME to consts...

stash: <type 'exceptions.ImportError'>: No module named consts

Any other ideas? Thanks in advance

ccc

I posted a GitHub issue... https://github.com/secdev/scapy/issues/598

inzel

@ccc Thank you!

abcabc

Pythonista does not support modules like subprocess. Hence I think that you may not be able to run this on pythonista.

I am able to install it but it gives error while running (not able to start the interactive session).

inzel

@abcabc Interesting. So how are people actually using scapy then? Just running it from a script? Seems odd that there is no interactive shell to test on..

ccc

@inzel Can you please respond to https://github.com/secdev/scapy/issues/598 by posting a full stack trace there?

yolelechamp64

@abcabc Not at all, that was an old windows bug...

yolelechamp64

@inzel Scapy is a very complete program. There are tons of usages:

using the scapy shell (based on the python code.interact shell)
directly from a script (it's easily importable)

It does not support IOS devices, neither pythonista. It works on Mac though...

Indeed the code integration is quite complex: for instance we need to detect the networking routes on the device, using a different way for every OS (we have a custom support for linux, windows, Mac...), as it's not supported in Python.

If we want to support IOS, there will be a lot of edits to do.

I would like to know if we will be able to support python on IOS one day, so if someone could answer those questions if would be great:

Does pythonista supports RAW sockets ?
Are there different networking interfaces ? Are they all detectable/accessable ?
Does pythonista/IOS supports IPv6 ?
Is it still impossible to get the device's MAC ? (pretty sure it was so in the past)

Thanks for reading.

I don’t think this is feasible with iOS. I tried running

socket.socket(s.AF_INET,s.SOCK_RAW,s.IPPROTO_ICMP)

as part of an experimental host scanner and got operation not permitted. It might work on a rooted device but I’m not going to do that.

Cheers
