Compiling Bitcoin Core Source Code : Ubuntu 16.04 LTS

1.   Bitcoin Core is the reference implementation of bitcoin and anyone ON with any projects around bitcoin would need to compile the bitcoin source code to create the bitcoind for his/her own node. Ubuntu is usually the operating system recommended to run Bitcoin Core.This post will build upon with screenshots as done and terminal commands as executed to compile the same vide GIT.

2.  The machine I have used here is a Ubuntu 64 bit running on a virtual box platform with the following details as seen in the screenshot :

Now on I will just share the terminal commands as i executed in the terminal :

sudo apt-get update

sudo apt-get upgrade

sudo apt-get install git

Search for Bitcoin github and click the first link as seen below :

Goto the link as seen below at https://github.com/bitcoin/bitcoin/blob/master/doc/build-unix.md

sudo git clone https://github.com/bitcoin/bitcoin.git

sudo apt-get install build-essential libtool autotools-dev automake pkg-config libssl-dev libevent-dev bsdmainutils python3

 

sudo apt-get install libboost-system-dev libboost-filesystem-dev libboost-chrono-dev libboost-program-options-dev libboost-test-dev libboost-thread-dev

 

sudo apt-get install libboost-all-dev

ARACHNI Web Scanner

1.    When we start finding vulnerabilities in a web application,either we have a option to do it manually by putting in hours of patience and grilling or we generally hear the commonly used tools like Acunetix and few other online scanners...or for may be afford a luxury like IBM - Proventia Network Enterprise Scanner ..but there is an open source tool option to Acunetix. Takes lil bit of time but the amount of options that it offers are huge...and gives a great report that is exhaustive.

2. Arachni is an Open Source, feature-full, modular, high-performance Ruby framework aimed towards helping penetration testers and administrators evaluate the security of web applications. It is smart, it trains itself by learning from the HTTP responses it receives during the audit process and is able to perform meta-analysis using a number of factors in order to correctly assess the trustworthiness of results and intelligently identify false-positives. It is versatile enough to cover a great deal of use cases, ranging from a simple command line scanner utility, to a global high performance grid of scanners, to a Ruby library allowing for scripted audits, to a multi-user multi-scan web collaboration platform.

3.   Arachni is a fully automated system which tries to enforce the fire and forget principle. As soon as a scan is started it will not bother you for anything nor require further user interaction.Upon completion, you will be able to export the scan results to several different formats (HTML, Plain Text, XML, etc.).Few useful pointers about details of this good scanner :
