Error:Traceback. #15

Closed r00tb3 closed 6 years ago

r00tb3 commented 6 years ago

I'm getting the following error:--

Traceback (most recent call last):

Tried with python2.7/3/3.5 it runs only with 2.7 with the error above.

After going through closed issues I figured out to move the fat.py and reset.py to firmadyne directory and start the PostgreSQL service but now I get the following error:--

To bypass the authentication error this worked for me :--

sudo apt-get install postgresql

sudo -u postgres createuser -P firmadyne, with password firmadyne

sudo -u postgres createdb -O firmadyne firmware

After that running fat.py gives me EOF error again:--

I guess the problem is with the database ID but I don't know how to resolve!!

Please help me resolve. Thanks!

extremecoders-re commented 6 years ago

The scripts are intended to be run on Python 2.7 and wont work with other versions.

Looking at the error trace, the database is probably not configured. Can you try the steps below

  1. sudo apt-get install postgresql
  2. sudo -u postgres createuser -P firmadyne, with password firmadyne
  3. sudo -u postgres createdb -O firmadyne firmware
  4. sudo -u postgres psql -d firmware < ./firmadyne/database/schema

@extremecoders-re

I've already followed the steps above but now I'm stuck on this:--

I figured out what the prob was...

In firmadyne.config the var FIRMWARE_DIR I mistakenly replaced the var to my location of firmadyne and messed up everything now I've set the var correctly and everything is working fine.

Thanks for the support.

extremecoders-re commented 6 years ago

@V33RU From the error trace, it looks like qemu-system-mips is not installed.

command: /usr/bin/sudo
args: ['/usr/bin/sudo', '/root/firmware-analysis-toolkit/firmadyne//scripts/inferNetwork.sh', '1', 'mipseb']
buffer (last 100 chars): ''
before (last 100 chars): 'e-analysis-toolkit/firmadyne//scripts//run.mipseb.sh: line 25: qemu-system-mips: command not found\r\n'

You can run qemu-system-mips in a terminal to check whether its installed properly.

To install just qemu-system-mips you can run sudo apt-get install qemu-system-mips or alternatively sudo apt-get install qemu-system to install qemu for all supported archs.

yangshouguo commented 6 years ago

maybe you need try your binwalk and see if it works correctly.

I've had the same problem. It's been bothering me for a long time. However, I don't think the problem arises from the wrong path. What should I do?

Can you please tell me the exact setup by which you actually installed all the tools, because looking at the log it looks more like a bit of a misconfig issue.

wangyankun17 commented 5 years ago

Thank you for your patient help

The following is the beginning of firmadyne.config `#!/bin/sh

uncomment and specify full path to FIRMADYNE repository

FIRMWARE_DIR=/home/lessiewang/firmware-analysis-toolkit/firmadyne/

specify full paths to other directories

BINARY_DIR=${FIRMWARE_DIR}/binaries/ TARBALL_DIR=${FIRMWARE_DIR}/images/ SCRATCH_DIR=${FIRMWARE_DIR}/scratch/ SCRIPT_DIR=${FIRMWARE_DIR}/scripts/

functions to safely compute other paths`

The following is the beginning of fat.py

`#!/usr/bin/python

import os import pexpect import sys

Put this script in the firmadyne path downloadable from

https://github.com/firmadyne/firmadyne

Configurations - change this according to your system

firmadyne_path = "/home/lessiewang/firmware-analysis-toolkit/firmadyne" binwalk_path = "/home/lessiewang/firmware-analysis-toolkit/binwalk"`

Infiltra commented 5 years ago

In my case, the same issue was resolved by having the fat.py file in the same directory as that of firmadyne directory. It might be the issue as I find no problems with your installation and path specs and just for confirmation check your binwalk path as well, sometimes that might also cause an issue.

wangyankun17 commented 5 years ago

Thank you for your sincere suggestion. I tried it, but it didn't seem to work. I'll try something else. If it works, I'll come back.

flamecopper commented 2 years ago

Could this be the reason, the extractor.py mention password is toor.

self.database = psycopg2.connect(database="firmware", user="firmadyne", password="toor",

However, the installation manual say the default password is firmadyne
