How can I install Scapy?

pythonista72

Hi,

just read about 2.0 release, great! :-)

But one question. How can I install something like Scapy?
http://www.secdev.org/projects/scapy/

It's a complete package with many files...

Thank you for your help!

Try using the pip command in StaSh. I guarantee that you will find yourself using StaSh in the future for other tasks as well.

I use this appex scripts for downloading things into pythonista:

import urllib2, appex, time, zipfile, os
a=time.time()
if appex.is_running_extension():
	url = appex.get_url()
	print url
	e=0
else:
	import clipboard, editor
	url = clipboard.get()
	e=1

response = urllib2.urlopen(url)
file = response.read()

name = url.split('/')[-1]
home = os.path.expanduser('~/Documents/')
output = open(home+name, 'w')
output.write(file)
output.close()

print 'Downloaded '+name+' to /Documents/'+name+' in '+str(time.time()-a)+' seconds'

if zipfile.is_zipfile(home+name):
	print 'Extracting zip...'
	zipfile.ZipFile(home+name).extractall(home)
	os.remove(home+name)
if e:
	editor.reload_files()

Go to the scapy website, download the zip. Once you see it in Safari like this:

Click "Open in…", select pythonista, then run my script. Returning to pythonista, you should see a folder scapy-2.3.1. Go into this, and move the scapy subdirectory into site-packages

@Webmaster4o Is that the right screenshot? :)

Gerzer

@Webmaster4o Nevermind, I see you changed it.

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!

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!

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).
