Tunneling with Putty

Tunneling with Putty

Motivation

I would like to create a ssh with a remote instance. Usually ssh is very secure, you can put password and key pair security. However it could be difficult to do other things in a more visual way, so we “tunnel” through the ssh connexion (taking advantage of it security).
Here for a better explanation of Tunneling and ssh conection: https://chamibuddhika.wordpress.com/2012/03/21/ssh-tunnelling-explained/


Set up

Preliminars:
  • Of course the possibility of doing ssh is key.
  • If you are going to “tunnel” using different port make sure those are open.
You just have to issue your standard Putty session and add “X11 forwarding” as shown here:
Also you should think which is going to be the port from your handy computer to the one you are connecting to. I want to use the port 8888 of the receiver and I am going to use port 9100 in the local machine:
Make sure you press ADD, and open and/or save.
Now you can connect:

Making MongoDB remotely available.

Imagen
Summary Here I show how to make your MongoDB accessible from a different server / computer/ instance, without using ssh. Motivation I have been using MongoDB to store and query some databases. This databases has been shared with other people and in most of the cases I have managed to use it as localhost or using ssh. However when using Docker it is easy to run into problems when using ssh. It is common to access other databases such as MySQL. For example in to use MySQL in Python you could have something like this: import pymysql.cursors # Connect to the database connection = pymysql.connect( host = ' localhost ' , user = ' user ' , password = ' passwd ' , db = ' db ' , charset = ' utf8mb4 ' , cursorclass = pymysql.cursors.DictCursor) In the same line you could query your MongoDB using ...

How to create a function in python to be used from the terminal

Imagen
To write a python code able to read variables or inputs from the command line you only have to use sys.argv. Let's see a couple of examples. You can find the code here . File called example_v1.py: import sys def main(): print sys.argv if (__name__ == "__main__"): main(); Then you go to the folder where you have it and run this comman in the comman line: python example_v1.py Like here: As you can see the output is the name of the file. Let's try this: python example_v1.py hi hola ciao Basically the comand sys.argv is giving us a list of the commandline arguments received. Now I am going to create a program that is going to say hi and the name that you introduce after file name in the commandline. I called this script example_v2.py: import sys def main(): print 'Hi ' + sys.argv[1] + '!' if (__name__ == "__main__"): main(); So now we can write in the terminal: python ...

Los mercados y las pensiones.

En estos tiempos muchos tratan a de demonizar a los mercados, en particular a los mercados de compra y venta de deuda pública, sin embargo, lo que no se dice es que estos mercados tienen en consideración y ponen a examen la economía y sostenibilidad de un país en su conjunto. Así que siendo realistas España tiene una serie de problemas  a corto, medio y largo plazo que también valoran los mercados. España tiene un sistema educativo en el que un alto porcentaje de alumnos no terminan la educación obligatoria, una universidad con poco prestigio  y proyección internacional. España dependen sobremanera del turismo (¿qué pasara cuando los países del norte de África vuelvan a ser relativamente seguros?). Nuestro inmenso paro, nuestras bajas tasas de innovación, nuestras altas tasas de pobreza relativa y creciente desarraigo. Pero no olvidemos algo mucho mayor, nuestro sistema de pensiones cuya sostenibilidad es bastante dudosa. Sobre el tema de las pensiones hay argumentos e...
