Netcat nc

Netcat, kurz nc, ist ein universelles Kommandozeilenwerkzeug. Es kann im Terminal oder in Skripten für die Kommunikation über TCP - und UDP -Netzwerkverbindungen (Internet Protocol Version 4 und Version 6), aber auch lokale UNIX Domain Sockets genutzt werden. Damit eignet es sich für zahlreiche Anwendungsfälle zum Thema Netzwerkverbindungen Netcat, auch nc genannt, ist ein einfaches Werkzeug, um Daten von der Standardein- oder -ausgabe über Netzwerkverbindungen zu transportieren. Es arbeitet als Server oder Client mit den Protokollen TCP und UDP. Die Manpage bezeichnet es als TCP/IP swiss army knife (Schweizer Taschenmesser für TCP/IP)

Netcat can be a useful tool for any IT team, though the growth of internally managed network services and cloud computing make that particular environment a natural fit. Network and system administrators need to be able to quickly identify how their network is performing and what type of activity is occurring Netcat is not restricted to sending TCP and UDP packets. It also can listen on a port for connections and packets. This gives us the opportunity to connect two instances of netcat in a client-server relationship. Which computer is the server and which is the client is only a relevant distinction during the initial configuration

Netcat can perform basic client/server functions that allow 'chat' between machines. On one console, start nc listening on a specific port for a connection: # On a computer A with IP we listen on port 64 $ nc -l -p 64. nc is now listening on port 64 for a connection. On a second console (or a second machine), connect to the machine.
