What Me Worry?

What me worry?

What? Me Worry?
Not with this stuff
Nobody gettin’ in
Nobody get tough

I’m a comic book kid
Having fun in the woods
Carving out toys
and makin’ em good

Ya it’s spy versus spy
I got so many tricks
I got undercover agents
Even out in the sticks

Threw a brick through your window
Ya it’s teenage fun
Then I blew up a bridge
And blocked out the sun

Little black flies
on a pile of GNU
With a Dairy Queen tip
And Imma comin’ for you

Make fun of everybody
That’s my thang
Ya It’s a geeks wet dream
I give a poit! blit! spang!

It’s a mad mad world
and number 5 is alive
I gotta black submarine
and I’m built to survive

Threw a brick through your window
Ya it’s teenage fun
Then I blew up a bridge
And blocked out the sun

Keep the source open
Gonna get my kicks
I’m 16 now
Ya I don’t need mix

Got a stack o magazines
In my treehouse club
Nobody gettin’ up here
Its secure ya bub

Got a dime store bazooka
And a bubble gum tank
Got pots and pans for cookin’ up
some Open source stank

Threw a brick through your window
Ya it’s teenage fun
Then I blew up a bridge
And blocked out the sun

Presentation comparing pf and iptables

If you working with Linux or Unix (Open|Free)BSD, you probably got in situation to use their firewall tools. Linux has its iptables, and originally in OpenBSD there is pf ( packet filter )

Couple years ago, I gave an short presentation about these two firewall tools, you can find it at below link

PF_IPTABLES

I find it interesting as an comparative overview, but improvements are welcome.

Building redundant firewall using OpenBSD tools PF and CARP

I think OpenBSD is very good Unix distribution. It is secure, easy to maintain and free. I like it because of its security model, and I find it as very convenient and excellent choice for various networks servers firewall, dns , loadbalancer, etc.

At below link you can find presentation I gave on this topic, it is related to how to build HA firewall using OpenBSD and its tools : CARP and PF

In some of my future blog posts I will write detailed howto, how to set up HA firewall, where I am going to describe hardware requirements, and step by step software configuration
