Installing Ruby with rvm
May 22, 2016, 11:31 a.m. by Nitin Venkatesh

From the time I discovered rvm, it has become the way of installing Ruby on a Linux box. So what is rvm? From the official page, RVM is a command-line tool which allows you to easily install, manage, and work with multiple ruby environments from interpreters to sets of gems. And that is exactly what it is. It helps you ...

Fixing errors while installing Metasploit Framework on Ubuntu
June 24, 2015, 8:11 a.m. by Nitin Venkatesh

I followed the excellent instructions by darkoperator to install the Metasploit Framework on Ubuntu. However, I had a tiny hiccup when it came to doing the bundle install. (The bundle install step is in the section marked Installing Metasploit Framework in the instructions guide). I got the following error: Errno::EACCES: Permission denied @ rb_sysopen - metasploit-framework-4.11.0.pre.dev.gem An error occurred while ...


WARNING: Sourceforge has gone ROGUE!
May 28, 2015, 12:49 p.m. by Roland Taylor

This is not a joke. First it was GIMP For Windows, now as others are reporting, Sourceforge has turned evil and is now distributing adware and malware with open source software. If you use Sourceforge for any downloads, stop. If you've got Sourceforge links, take them down. Again, this is not a joke. It's one thing for a company to ...


Finding ModSecurity version info
March 7, 2015, 8:06 p.m. by Nitin Venkatesh

If like me, you installed ModSecurity on Ubuntu or a Debian machine with something like $ sudo apt-get install libapache2-mod-security2 , we might end up clueless trying to find the mod_security.c file (as suggested in a few places) because the LoadModule in the Apache config uses a .so file. But whether you're using Ubuntu, Debian or CentOS, there is an ...


Setting up chroot jails for your vsftpd users
Jan. 23, 2015, midnight by Nitin Venkatesh

chroot jails keep your users locked in a directory and not let them wander about the filesystem to places they have no business poking their noses into. Alrighty, let's implement this in our vsftpd server so that you don't have your FTP users peeking at the passwd and shadow files. We assume you've already created your FTP user and have ...

Dec. 14, 2014, 8 a.m. by Nitin Venkatesh

So, you've setup OWASP ZAP and are routing your browser's traffic through it and are ready to do some digging, but everytime you hit a site, you get an annoying SSL Security Exception error and when you view the certificate, it is the OWASP ZAP Certificate.

Wordpress comments RSS feed for posts by a single author
Nov. 23, 2014, 6:31 a.m. by Nitin Venkatesh

Wordpress offers a plethora of RSS feeds right out of the box. It's pretty well-documented at the Wordpress.org Codex - Wordpress Feeds page. One thing that was missing from the documentation, and for which I was actually looking for when combing through it in the first place, is the hidden feature of retrieving all comments made on posts by a ...


Accessing your Virtualbox Guest from your Host OS
Nov. 8, 2014, noon by Nitin Venkatesh

We all use VirtualBox to setup our playgrounds and experiment(wreck) everything without ever having to bear the repercussions. Sometimes, we want to access this guest machine from our host, but we fail. For example, I have an Ubuntu guest (nitin-VirtualBox) running inside my Ubuntu host(trusty) and I want to access the Apache Web Server running on my guest. Running an ...


Installing vim.basic - making vi normal again
Oct. 5, 2014, 8:24 a.m. by Nitin Venkatesh

On Debian and other Debian-based distros, when you use Vim, you might find it a little weird. For example, in the insert mode, when you press the arrow keys, you end up with inserting characters - A, B, C and D which gets confusing for people new to the editor (like me). This is because Debian uses the vim.tiny configuration ...


Monitoring webpages with Last-Modified and ETag headers
July 14, 2014, midnight by Nitin Venkatesh

Most sites have a lot going on in their HTTP headers which can sometimes help us easily identify if the web page has changed since the last time we visited it. This ofcourse depends on if the server responds with these headers and has been configured correctly to reflect any changes in the headers. Enough said, so when we query ...
