Backtrack 5 R2 - Scapy

[triplexxx]

Hallo!

I am using the Live-Cd Backtrack 5 R2 Gnome. The installed version of scapy of this Live-CD is v2.0.1. In this version, I think there is a bug. When I am executing an ELF that uses scapy, it allways gives an error that tells me that tcpdump is not installed despite it is installed. I found out that the error comes from a wrong path definition in the file the linux.py.

But the ELF I want to execute needs scapy v2.2.0. Therefor I went to http://www.secdev.org/projects/scapy/, downloaded v2.2.0 and installed it:
# chmod +x scapy.py
# ./scapy install

But when I execute scapy, Backtrack tells me, that v2.0.1 is installed a not v2.2.0. I am not able to install v2.2.0.

Can anyone tell me how to install v2.2.0 correctly?

Thany you very much!

Solved!!

You have to install scapy using the following command:
# cd scapy-2.2.0
# chmod +x setup.py
# ./setup.py install --user

--user was missing!

Now it works pretty fine!

triplexxx,

The reason that this is happening is that both the scapy and the python-scapy is installed. the version of just scapy is 2.2.0-dev.

apt-get purge python-scapy

and just install scapy

apt-get install scapy

this fixes my error.
I do get this error:
WARNING: No route found for IPv6 destination :: (no default route?)
Welcome to Scapy (2.2.0-dev)
but the this can be suppress if you like by adding

import logging
logging.getLogger("scapy.runtime").setLevel(logging.ERROR)

before importing Scapy to suppress all messages below error messages

Getting some other errors, besides the IPv6 dest one:

INFO: Can't import python gnuplot wrapper . Won't be able to plot.
INFO: Can't import PyX. Won't be able to use psdump() or pdfdump().

... any ideas?!?

Thanks,
