# This can be used with the debug build option ZT_TRACE_MULTICAST to trace |
|
# a multicast cascade. |
|
# |
|
# Define ZT_TRACE_MULTICAST to the IP/port where this script will be listening. |
|
# The default port here is 6060, so an example would be to add: |
|
# |
|
# -DZT_TRACE_MULTICAST=\"10.0.0.1/6060\" |
|
# |
|
# ... to DEFS in the Makefile. Then build and run ZeroTier One on a testnet and |
|
# the box defined as the trace endpoint will get spammed with UDP packets |
|
# containing trace information for multicast propagation. This script then dumps |
|
# these trace packets to stdout. Look at the code in PacketDecoder.cpp to see |
|
# what this information entails. |
