simple utility to test multicast routing
In troubleshooting multicast routing I wanted a lightweight multicast message sender and receiver. mctk provides an extremely lightweight process that can send packets to a multicast group at a configurable rate of a specified size (to test MTU). it also can receive the packets.
Written in Rust, it is runs on any platform that Rust supports. It has been tested on Linux (Redhat 6/7) and Windows 10.
This will send small multicast packets every 1 second to the 224.1.1.1 multicast group.
mctk send -g 224.1.1.1This will join the group, and receive multicast packets.
mctk receive -g 224.1.1.1In both send/receive you can specify the port (-p). In send you can also specify the sending interval in milliseconds (-i) and the packet size in bytes (-s).
$ mctk -h
