# tcpv4tracer Trace TCP connections.
# For Linux, uses BCC, eBPF. Embedded C.
#
# USAGE: tcpv4tracer [-h] [-v] [-p PID] [-N NETNS] [-4 | -6]
#
# You should generally try to avoid writing long scripts that measure multiple
# functions and walk multiple kernel structures, as they will be a burden to
# maintain as the kernel changes.
# The following code should be replaced, and simplified, when static TCP probes
# exist.
