Haven't written much lately, but it is time to come back to share experiences and findings. So I expect the blog to grow in the coming months and therefore a search function starts to become a need. Actually, there is already a decent amount of posts in the blog and the current navigation makes very painful to find an old post . Moreover, I'm using the same blog platform pBlog for my side project ROOR (Revista Online Occam's Razor... and online technical magazine), that contains also a few tenths of posts.

Almost 2 years ago I wrote about a PoC Crypter for GNU/Linux. In the meantime I had learned a couple of things and it's time to revisit that old post and update it with new and fresh information.

PROGRAMMING
Some years ago I participate in a challenge. It went fine and all participants got some feedback afterwards so we could figure out what we had done wrong. As part of that feedback, the question of re-using parameters within function rose... so I decided to look into the details.

Not so long ago I had to configure a machine following some strict rules. It was pretty painful and, when I was done, I was asked to provide an image of the configured machine to some remote team to do some checks on it. The machine was installed in a 1 TB disk, so making and image and send it around will require quite some time (either to transfer the file or to wait for the post to deliver some physical storage device).

A SYN scan is, maybe, one of the simplest stealth port scanning techniques you can think about. There are some claims around the Internet about how it works and I was curious to know more about thats. This post summarises my findings.

For many years I have successfully used the techniques described in Four Unorthodox Ways to Transfer Files, for my transfer need. But, recently, I found a case where none of those techniques worked. So I have to come up with innovative ways to deal with the that.

tee
and splice
long ago. I quickly went through the man pages and, like in the Matrix movie I said to myself.. "I know tee and splice". Recently, I have to write some code that perfectly matched the functionality of these two system calls... but when I tried them.
BLOG
Haven't write for a while about pblog. Actually I haven't done many changes on it lately but there were some... So, many of the changes you had probably already noticed. Maybe the most obvious was the use of Disqus for the comments. I'm still not fully convinced. I was almost ready with my own comment systems but spam was maybe the biggest problem to solve.
Anyway, if you are reading this, you have probably noticed that I can now post without a header image. Header images are really nice and give great visuals to the posts. But, sometimes, I have an idea to write, or even I have already written the post and it takes me a while to finally publish. Just because I cannot find a nice picture to use as header.
