MacPorts, formerly DarwinPorts, [4] is a package manager for macOS and Darwin.It is an open-source software project that aims to simplify the installation of other open source software. [5]
The port numbers in the range from 0 to 1023 (0 to 2 10 − 1) are the well-known ports or system ports. [3] They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the ...
WireGuard is a communication protocol and free and open-source software that implements encrypted virtual private networks (VPNs). [5] It aims to be lighter and better performing than IPsec and OpenVPN, two common tunneling protocols. [6]
Port forwarding via NAT router. In computer networking, port forwarding or port mapping is an application of network address translation (NAT) that redirects a communication request from one address and port number combination to another while the packets are traversing a network gateway, such as a router or firewall.
Using the reverse proxy of a third party (e.g., Cloudflare, Imperva) places the entire triad of confidentiality, integrity and availability in the hands of the third party who operates the proxy. If a reverse proxy is fronting many different domains, its outage (e.g., by a misconfiguration or DDoS attack) could bring down all fronted domains. [7]
My traceroute, originally named Matt's traceroute (MTR), is a computer program that combines the functions of the traceroute and ping programs in one network diagnostic tool. [ 2 ] MTR probes routers on the route path by limiting the number of hops individual packets may traverse, and listening to responses of their expiry.
XDP_REDIRECT: redirect the packet to another NIC or user space socket via the AF_XDP address family XDP requires support in the NIC driver but, as not all drivers support it, it can fallback to a generic implementation, which performs the eBPF processing in the network stack, though with slower performance.
In computer networking, a media access control attack or MAC flooding is a technique employed to compromise the security of network switches.The attack works by forcing legitimate MAC table contents out of the switch and forcing a unicast flooding behavior potentially sending sensitive information to portions of the network where it is not normally intended to go.
