The transport layer (where TCP and UDP reside) and the application layer are particularly important for this server course.
This video serves as the first class in a course on servers. The instructor, Carlos Andres Sarzuri Calizaya, introduces the course, outlines the curriculum, and begins discussing fundamental networking concepts like the OSI model, focusing on the transport and application layers. The latter half of the video transitions to practical command-line tools for network inspection and management, such as ping and curl, and discusses critical ports and protocols like SSH, HTTP, HTTPS, and DNS.
ping, netstat (implied by ss command), and curl are demonstrated for network diagnostics and information retrieval.La tarea mencionada en el video consiste en investigar el comando ss -tulnp. Específicamente, se pide identificar cuál de los servicios que aparecen es SSH y por qué se escucha en el puerto que está asignado. El instructor sugiere que esta será una tarea de investigación sencilla y que mañana se enviará un formulario para obtener puntos extra relacionados con ella.
