Zen attention

Attention is one of the most powerful features of the human mind. In Zen, attention allow us to be "here and now", with no errors, without losing energy in other thoughts and with a clear mind.

You can train attention through meditation and in you everyday tasks and life. That demands hard work, you can't allow your mind do what it wants, it must do what you want. With this awareness you are always in the present (there isn't nothing more than the actual moment)

At the same time, attention is useful against fears, stress or problems, because you can see the moment that that thoughts begin to appear, because you only made one thing at a time. In the work, at home or in your spiritual life, you always must pay attention.

Avoid SPAM in Internet

I will assume all the network administrators close the SMTP relay in their mail servers. But there is another important thing to do against SPAM which is not configured for everybody: close SMTP port in the firewall (or router) outgoing rules.
This is, not allow SMTP traffic leave your organization (or home), or if necessary only allow your IP email server address. In this way, you can be sure spammers can't use your network, SPAM is not send from your company. What will happen if everybody takes the same security action?

It's so easy as:

access-list ACL_OUTGOING deny tcp any any eq 25
access-list ACL_OUTGOING permit ip any any

Dan Brown, The Lost Symbol, Noetic Science and Zen

I've bought at Amazon the new Dan Brown’s novel, The Lost Symbol, and it has produced at me a great interest in Noetic Science. This science studies the effect of the mind over the body and physical world, the existence of an universal mind which all of us take part, we are a whole, like a human body who is formed from millions of cells, we are all interconnected in a subatomic level (our human cells are together with the air atoms and next to other human cells, without space between them) all is a whole in movement, thoughts have a power, there is a God within us (and not only outside), we have the power to change the world, and things like that.

For me, all this stuff is interesting because it connects in a scientific level and tries to demonstrate issues that I have heard before in a more spiritual environment, like it can be ZEN philosophy, as well important for me.

I haven't finished the book yet, but i think is a very interisting one

Deploying a secure wireless network

Today if you want to create a “SECURE” (the most secure) wireless network, you must use WPA2 wit AES and EAP-TLS. To deploy it, you’ll need to configure your Access Point with AES encryption and authentication through a Radius Server with user and server certificates, this is EAP-TLS.



So you need a PKI infrastructure to manage the user certificates. It could be hardworking to deploy, but it’s very easy to maintain and you’ll never get worried about pre shared keys and their distribution.

Moreover, you always have the radius log with all the access to your wlan and with the name of each user.

To hide or not the SSID doesn’t matter, if you hide it a hacker can easily discover it with a wireless sniffer, like Kismet (very easy to install in Ubuntu, for example)

I've always found extraordinary that when I'm in trouble the solution can be found in Internet. Yes, someone has shared it without expecting nothing in return. So, this blog is born to return something of that and to be part of this community that built Internet.
