Hard links vs soft links in Linux
April 30, 2015, 9:02 p.m. by Nitin Venkatesh

There are two types of links in the Linux world that you'll come across - hard links and soft links.

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 ...

A new browser is among us, in the form of Vivaldi, and it's all about bring the old to the new. This is a good thing.

If, like me, you've been: On the interwebs for long enough A power ...

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 ...

Setting up vsftpd on Ubuntu

So what I ended up doing is setting up FTP, making life much more simpler. Installating vsftpd vsftpd is a FTP server program. Install it on your remote machine with, $ sudo apt-get install ...

Using GlusterFS on Ubuntu Server
Jan. 1, 2015, 3:06 p.m. by Nathan Osman

One of the difficulties faced by fault-tolerant web applications is distributed file storage. Indeed, this is one of the many challenges we face here at 2buntu. We allow our editors to upload images to accompany their articles and these images must be available on each server used for serving the website.

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 Codex - Wordpress Feeds page.

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 ...
