issue plotting .cap files ScaPy Python3

Question

After reading .cap file using rdpcap successfully, I've been trying to use the function pdfdump but it keeps giving me an error:

"AttributeError: 'SingleTexRunner' object has no attribute 'texoutput' "

here's my code:

from scapy.all import *
import pyx

a = rdpcap("the file path..")
a.pdfdump("output filename")

anyone got an idea how to solve this issue?

Answer 1

I'm using Python 3.6.0

I've installed scapy with:

pip3 install scapy-python3

Using wireshark 2.2.3, I saved a dump using the default file format which is .pcapng

I've used the same code as you :

from scapy.all import *
import pyx

a = rdpcap("test.pcapng")
a.pdfdump("test.pdf")

and I obtain a valid pdf.

Answer 2

Use sudo apt-get install python3-pyx on Linux(Debian, Ubuntu...) to install pyx and its dependencies; installing pyx with pip install pyx is not enough.

Answer 3

Don't run scapy (if you use the command line) or your script as root. This fixed it for me.
