Detect man in the Middle

jeann — Sun, 01 Mar 2020 23:13:41 +0000

nmap -sn --script=sniffer-detect 192.168.0.102

"sn" This command is for "ping" scan, but it will not necessarily do an ICMP request.

"--script" This will tell Nmap to run a script. In this case, it was "sniffer-detect."

"sniffer-detect" This was the script name that we used for detecting the sniffer.

"192.168.0.108" This is the target network that may be compromised. In this case, this may not always work, so you can also scan the whole network by adding /24 after the gateway address. For example, in this case, it would be 192.168.0.1/24.

Learn is Hard, but learn all is so hard

jeann — Tue, 28 Aug 2018 12:02:38 +0000

I got 41 years old, I am a programmer, all my life is programming, C, C++, VB6.0, Php, Javascript, SQL, Ruby, Golang and more.

When I was 20 years old just with 3 technologies are enough to achieve success development application, like:

Languages like VB or Java or Pascal or C++, SQL (Structured Query Language) and a System Operative (Windows or Linux is last very weird), that is, with this is enough for development any applications.

Today is so more complicated because every day came up with new technologies, new paradigms, a new framework, each language came up every week new parches security, new stuff than learn, new stuff than change and adapt it, for example, a developer rookie have to know: a language like: Php or Javascript(ECMAScrip 2015 or 2017)or TypeScript or Ruby or Python or Golang or R or C# or Java(JSE, JEE) in some case 4 or 5 language, to they have to know technologies require: Javascript, Html and CSS and SQL is very basic which is a lot

Today to be a Senior developer is a lot more complicated than 15 years ago, these people have to know Desing Patterns, Methodologies Agiles, programming is a save way with standard of language, they have known many System Operatives(Windows, Linux, Unix, System Operativo Embedded or microsystem), minimal 9 o 10 languages(R, C, C++, Java, Php, Golang, Python, Pascal, C#, Solidity, etc), IA(Artificial Intelligent), DataMining and more.

Today is more hard be Senior because have known more, but the information is more easy get.

Thanks!

My First Hellow Word

jeann — Thu, 23 Aug 2018 04:19:42 +0000

My first program inteligent was with pencil and paper, Yes Really!, 1995 a computer was is not possible for buy, because I was 17 years old,
not working, my parents give me all, ehhhh; Ok, the basic, like money for the university, three food for day, clothes, shoe, only that, for me is OK,
because was just I need.

The closest a computer was in my head, in my imagination or in laboratory of my University.

My first hours the programming was Pascal, C, and C++, they was the languages in that years, was my first program was not print "Hello Word" else a sort arrays
with 100 numbers and exploit my head, was very amazing for me.In vacations my notebook it was my way of letting go of my desire to program and
remember clearly that was switch case of C for simulate IA (Inteligents Artifical),Jajajajajaajajaja, like that:

#include <stdio.h>
int main()
{
   char a;
   printf("Is not Raining Now?...(Y)es-(N)o \n");
   scanf("%c", &a);
   switch(a)
   {
    case 'N' :
        printf("Then Is Raining, Human!\n");
        break;
    case 'Y' :
        printf("Is not Raining, Human!\n");
        break;
   }
   return 0;
}

Realy that code is amazing for me in 1995 and my notebook was look very pretty

I hope will like my post.

See soon.

Rails Migrations

jeann — Thu, 23 Aug 2018 04:14:39 +0000

Rails Framework is very interesting, because put layer between programmer and database, you name is ActiveRecord,
very nice library of ruby for manipulate, data, structure of table and manipulate object of database for all Database, example:MySql, Postgresql,
SQLite,Oracle,Sybase,SQL-Server, etc.

For me, the most interesting are the migrations, because, we can control of version of database and this is very importante, for project large.

We can to do, on the console:

Example simple:

Inline rails generate migration Person.

Example Simple, but nice, with this example we can create inmmediately the script for create table on Database:

Inline rails generate migration Person name:string address:string.

ActiveRecord is a ORM ->Object-Rol Modeling and the with more Security.
