Busy This Week, Here’s A tcpdump example

This is a very granular filtering usage of tcpdump and it helps my understanding of the simply but powerful tool.

The Scrutinizer

I have been behind in my posts, and I have quite a few items to get posted. Today I wanted to walk through an example of tcpdump can be useful when tracking down malicious traffic on your network. I am going to use the example of IrnBot to demonstrate a handy technique. IrnBot (named after the Scottish drink IrnBru), also popularly known as Rinbot, produces a lot of traffic on port 1433, 2967 and 139. It also opens up a connection to irc servers on the outside over port 8080.

Living a Full Life Span (my thought)

Oftentimes, we pray to live long, probably, longer than the ones before us. The desire for long life thus, has robbed many of us of our joy when a loved one suddenly dies “prematurely”, our prematurity being years younger than the expected life expectancy of such individual.

However, recently, I started thinking differently. I see life solely as an existence for a particular purpose. Coming from the school of thought I belong to, a useful life ends when the purpose of such a life has been dutifully fulfilled. God does not live anyone roaming about here who has completed his assignment, no no. He sent us here for a purpose and watches to see how aligned we are to that purpose in a lifetime. Different purposes requires different duration to accomplish, therefore, the duration of one’s purpose determines the longevity of each man’s life.God is pleased when our lives are lived on purpose and He’s content to withdraw anyone from this earth as soon as the assignment is done with.

Living a full life span, therefore, is staying  up long enough to fulfill that assignment and, not just to stay here marking time when there’s nothing more to do. Premature death therefore, would be, dieing before a divine purpose is accomplished and not, before a certain age, as expected by mortal man. Jesus completed his assignment at age 33 and he said

It is finished“,

referring to his reason for coming here. Paul lived a much longer duration because his assignment required it.

A full life span is not necessarily 70 years or 90 or 100. It is the exact time duration required for your assignment. Seek to live according to purpose and to fulfill it. When the time comes to be taken out, age notwithstanding, you would be able to say, Yes, It is finished!

Persistence pays

A salesman knows very well that hardly (if at all ), would you sell an item on your first call and, unless you’re the President of a nation (even at that), you would often need to repeat your requests before they are granted.

Nothing comes to you so cheaply; you have to go hard and strong after it. The only way to prove your desire for a thing is how resilient you are at getting it. Myles Munroe said, … pursuit is the proof of desire. In my experience in the little time I’ve spent up here, I discovered you don’t get a thing until you insist on getting it and that, if you insist and stand your ground, no matter how long it takes, you’ll always get whatever you ask for  … always.

You could be determined but not have the tenacity to get your desire delivered. You would be discouraged when you face rejection time and again. However, if you insist on getting it, you would develop courage and stand your ground. That is the power of persistence… it never fails.

Stand your ground. Keep pushing. Don’t give up. You will get there.

Duties of a Man

Speaking of marriage and the requisite qualities expected from both contracting parties, we all (or at least, most of us) know what are the base qualities a man getting ready for marriage should possess. I will not go into that here.

However, something caught my attention and, the more I tried to ignore it, the harder it is to let go. In my observation (addressing the men folk) I have seen many men that have all the expected base qualities, otherwise, their spouses wouldn’t have signed the dotted lines in agreement with them.

Most married men are caring. Women have an acute need for attention. Alas! Very few men realise this innate desire in their wives, at least, in the first few years of marriage. For guys that have been used to hanging out with friends for long hours, even late into the night, they find it difficult to pluck their own feet out of the peer trap. They fail to realise that their status has changed, therefore, there must be a change in lifestyle… and trouble begins.

In a bid to make this as brief as to not abuse your patience, let me say this: ability to say NO to PEER PRESSURE is a very essential quality a man must cultivate before he ventures into marriage. Whatever you agree to or decides for outside, has a direct impact on your family as long as it affects your own life. A married man, therefore,  must learn to recognise his boundries, acknowledge the parties to which his allegiance lies and control himself in the things he allows himself to be influenced by, giving his family the highest priority after God.

God bless your home.

God, Give Us Christian Homes!

God, give us Christian homes!

I Love Python

The Zen of Python
Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
Special cases aren’t special enough to break the rules.
Although practicality beats purity.
Errors should never pass silently.
Unless explicitly silenced.
In the face of ambiguity, refuse the temptation to guess.
There should be one– and preferably only one –obvious way to do it.
Although that way may not be obvious at first unless you’re Dutch.
Now is better than never.
Although never is often better than *right* now.
If the implementation is hard to explain, it’s a bad idea.
If the implementation is easy to explain, it may be a good idea.
Namespaces are one honking great idea — let’s do more of those!

Take That Step


Its amazing how much thinking and planning often goes into preparing for an endeavour. Yes, planning is good because it guarantees that nothing takes you unawares and that you have what it takes to tackle any challenge and, ultimately, success.

That being said, it is equally not wise to spend all the time thinking in the name of planning. There are certain things you would never see or envisage sitting on the shore, you have to launch out, take a step. Life’s journey atimes is like an onion; you must unwrap it in layers starting from the first and outermost layer.

Don’t sit all day waiting for all your expectations and variables to fall in place before you move out…move out anyway and keep your vision in Focus.
As other steps follow, the other layers will be unveiled.
