title="Informatique">informatique</a>, <b>netcat</b>, également abrégé <b>nc</b>, est un utilitaire permettant d'ouvrir des connexions <a href="/wiki/R%C3%A9seau_informatique" title="Réseau informatique">réseau</a>, que ce soit <a href="/wiki/User_Datagram_Protocol" title="User Datagram Protocol">UDP</a> ou <a href="/wiki/Transmission_Control_Protocol" title="Transmission Control

Il est conçu pour être incorporé aisément dans un large éventail d'applications. En raison de sa polyvalence, netcat est aussi appelé le « <a href="/wiki/Couteau_suisse" title="Couteau suisse">couteau suisse</a> du <a href="/wiki/TCP/IP" class="mw-redirect" title="TCP/IP">TCP/IP</a> ».

Les paramètres peuvent comprendre une plage de ports et une variation aléatoire plutôt qu'un scan d'ordre décroissant par défaut. Il existe aussi une option qui permet d'envoyer des paquets <i>source-routed</i>, des paquets qui sont envoyés via des routeurs dont on spécifie les <a href="/wiki/Adresse_IP" title="Adresse IP">adresses IP</a>.
