Si ya hemos hablado en entradas anteriores de copiar ficheros mediante SCP usando un fichero PEM para autenticarse y de conectarse a un servidor por SSH con un fichero de certificado digital PEM, hoy seguimos nuestra serie dedicada al manejo de conexiones seguras con ficheros PEM con el uso de rsync.
Como veis son tips muy cortos pero verdaderamente útiles en ambientes como Amazon Web Services donde este tipo de autenticación es frecuente.
Lo único que debemos hacer en este caso es indicar el tipo de comunicación, mediante SSH y más concretamente usando dicha clave:
rsync -e "ssh -i miclave.pem"
Un ejemplo completo podría ser:
Creo que no soy el único que maneja a diario SSH para administrar servidores remotos desde la estupenda consola bash de Linux. Normalmente, el uso más frecuente, es autenticar usando un par usuario/contraseña, es decir algo así:
ssh administrador@dirección_equipo
Y luego introducir el password. Sin embargo, esta no es la única forma. Para mayor seguridad y sobre todo para evitar ataques de fuerza bruta, podemos generar un certificado digital en formato X.509 y guardarlo por ejemplo en un fichero .PEM, que almacenará dicho certificado codificado en Base64 y encerrado entre “—–BEGIN CERTIFICATE—–“ y “—–END CERTIFICATE—–“.
En algunos casos, debido principalmente, a que nuestro proveedor de Internet puede entender que una conexión que no produce ninguna comunicación en un tiempo debe de ser cerrada, nuestra conexión con un equipo remoto es finalizada inesperadamente.
Existe una solución bastante sencilla para evitar este problema. Desde el blog de nuestro colega LoPsT, leo el resultado a este problema.
Bastará con modificar el fichero ssh_config y añadir la siguiente línea, que nos indica que cada 60 segundos se envía un AYA (are you alive?) evitando que el proveedor piense que la conexión se encuentra inactiva, así:
En algunas ocasiones necesitamos acceder a algún servicio o aplicación que usa un puerto diferente al que por defecto tenemos permitido.
Esta mañana en el trabajo me he encontrado con la siguiente situación. Deseaba agregar el repositorio UbuntuGis para instalar algunos paquetes del mismo (Grass y Quantum GIS entre otros), pero al añadirlo:
sudo add-apt-repository ppa:ubuntugis/ppa
Me he encontrado con el siguiente problema:

En muchos casos no tendremos acceso directo a un PC, entonces existen diversas opciones para conectarnos a él, mucho de vosotros habréis usado Telnet, SHH, NX, etc. Todas me parecen buenas opciones, quitanlo la primera ya que el paso de información es en texto plano, con lo que si esnifan de nuestra red tendrán todos los mensajes enviados/recibidos.
Dicho esto, tenemos dos opciones principales para conectarnos a un PC, por SSH o por NX, quizás conozcáis ambos, básicamente un cliente NX se trae las X del sistema host generando un escritorio sobre el equipo que se conecta, parece buena idea para conectarse, de hecho lo es, ya os comentaré a través de otra entrada una forma sencilla de configurarlo. Ahora simplemente me gustaría que probaseis a traeros las X de un equipo Linux desde otro equipo Linux mediantes SSH, para ello basta con conectarse añadiendo la opción -X:

The UK has been cracking down hard on CFD and forex brokers in the past few years. Included in this ban was F1Markets Ltd, the parent company behind Fxclearing.com and several other brands. This wave of bans was in reaction to a campaign by multiple brokers that involved the use of fake celebrity endorsements. The FCA claims that UK traders have lost hundreds of thousands of pounds due to these endorsements. This question has an answer that consists of a complex number of items that need to be discussed. The fist of these are the reviews that are provided online by the past users of the brokerage. A vast majority of the reviews, on the other hand, list a number of issues which all stem from the fact that the company ended up marketing the services it provides in a false manner. So, in theory, the broker can be trusted to provide a service that they promised, but only as long as the service is fully understood.
This way the users will think that it is better to deposit more money with the company. Fxclearing.com claims to be an industry leading online trading platform, specializing in stocks, commodities, indices, CFDs and currencies. They offer a unique and fully transparent trading model which guarantees best price execution. In any case, Vanuatu is an offshore zone and we recommend that traders choose carefully the brokers they will work with. We recommend that all investors and traders avoid Europrime and other Vanuatu brokers. Some brokers may provide a wide variety of trading products, while other brokers may specialize in one area, such as foreign exchange. Traders should trade with well-regulated brokers and reputable brokers.

Although HODLers will probably not notice a big impact, Taproot could become a key milestone to equipping the network with smart contract functionality. In particular, Schnorr Signatures would lay the foundation for more complex applications to be built on top of the existing blockchain, as users start switching to Taproot addresses primarily.
