Packet Sender is an open source utility to allow sending and receiving TCP and UDP packets. It also supports TCP connections using SSL , intense traffic generation, HTTP(S) GET/POST requests, and panel generation.
Storage : 4 GB: GPLv3: Free: IPFire is a hardened Open Source Linux distribution that primarily performs as a Router and a Firewall; a standalone firewall system with a web-based management console for configuration. Kerio Control: Active: Linux: x86-64: Proprietary: Paid hardware or virtual appliance: Router/firewall distribution. LEAF Project ...
The program is allowed to edit the packet data and, after the eBPF program returns, an action code determines what to do with the packet: XDP_PASS: let the packet continue through the network stack; XDP_DROP: silently drop the packet; XDP_ABORTED: drop the packet with trace point exception; XDP_TX: bounce the packet back to the same NIC it ...
The Windows Package Manager (also known as winget) is a free and open-source package manager designed by Microsoft for Windows 10 and Windows 11. It consists of a command-line utility and a set of services for installing applications. [5] [6] Independent software vendors can use it as a distribution channel for their software packages.
Wireshark is very similar to tcpdump, but has a graphical front-end and integrated sorting and filtering options.. Wireshark lets the user put network interface controllers into promiscuous mode (if supported by the network interface controller), so they can see all the traffic visible on that interface including unicast traffic not sent to that network interface controller's MAC address.
Netfilter is a framework provided by the Linux kernel that allows various networking-related operations to be implemented in the form of customized handlers.Netfilter offers various functions and operations for packet filtering, network address translation, and port translation, which provide the functionality required for directing packets through a network and prohibiting packets from ...
eBPF is a technology that can run programs in a privileged context such as the operating system kernel. [5] It is the successor to the Berkeley Packet Filter (BPF, with the "e" originally meaning "extended") filtering mechanism in Linux and is also used in non-networking parts of the Linux kernel as well.
Additionally, the routers will use reverse-path forwarding to ensure that there are no loops for packet forwarding among routers that wish to receive multicast packets. When a data packet is received on a non-RPF interface, a mechanism is required to prevent loops. If the non-RPF interface is a LAN, an Assert message is sent.
