The omping tool is a pure UDP client and server wrapped in a small binary. Perfectly suited for verifying multicast connectivity on your local network.
Compared to traditional ping omping does not use ICMP. It is based on RFC draft http://tools.ietf.org/html/draft-ietf-mboned-ssmping-08 and can thus test many different aspects of a setup:
“In addition to checking reception of multicast (SSM or ASM), the protocol can provide related information such as multicast tree setup time, the number of hops the packets have traveled, as well as packet delay and loss.”
Features:
- Similar user experience as classic ping tool
- Ping multiple hosts at once
- Any-source and Source-specific Multicast
