I wanted to experiment with sniffing data on the network. Of course, my own network. This was not a creepy sniffing of my neighbours’ network. I was keen in converting my Ubuntu VM into a router VM. Then I can redirect all traffic from ‘client’ VM via the ‘router’ VM on which the sniffer is […]
Often times I get into a situation where I mess up with my development (of personal projects). Though I use github for personal projects yet sometimes it is convenient to have a local SVN for all silly works (like .vimrc, .bashrc, etc…). After a lot of procrastination, I decided to set a local svn repo […]

So, my search was for a similar tool […]
How many of you are bored of typing your password every time you run a sudo command on your personal computer?! This is a bloody waste of time! I mean, I appreciate the sudoer jazz and the importance of security but then this is my freaking single-owner-only laptop! Why do I need to type password […]
Ubuntu comes with a pre-locked ‘root’ user. That is, root account is not accessible, not login-able but exists nevertheless. The default user (or the primary user) owns the sudo rights. Hence this user has all rights to perform “on behalf” of the root. But still root account, sometimes, is very important and useful. The question […]
