This is a small program as a tester for a basic sweep generator for bandwidth testing of AudioScope.sh.
This DEMO is only capable of 4KHz down to about 85Hz and back due to the low bit rate, but it is proof of concept for a much wider variant using a much higher bit rate.

mrinfo
mrinfo(8) System Manager's Manual mrinfo(8)NAME
mrinfo - Displays configuration information from a multicast router
SYNOPSIS
/usr/sbin/mrinfo [-d debug_level] [-r retry_count] [-t timeout_count] multicast_router
OPTIONS
Sets the debug level. When the debug level is greater than 0 (the default), additional debugging messages are printed. Regardless of the
debug level, if an error condition occurs, mrinfo writes an error message and terminates. Nonzero debug levels have the following effects:
Prints packet warnings to stderr. Prints all level 1 messages and notifications of down networks to stderr. Prints all level 2 messages
and notifications of all packet timeouts to stderr. Specifies the number of times to retry a neighbor query. The default is 3 retries.
Specifies the number of seconds to wait for a neighbor to reply to a query. The default timeout is 4 seconds.
DESCRIPTION
The mrinfo command displays the configuration information from the multicast router multicast_router.
The mrinfo command sends the ASK_NEIGHBORS IGMP message to the specified multicast router. If the multicast router responds, the response
includes the version number and a list of addresses for their neighboring multicast routers. If the responding router has a recent multi-
cast version number, mrinfo requests additional information such as metrics, thresholds, and options from the multicast router. Once the
specified multicast router responds, the configuration is displayed to the standard output.
RESTRICTIONS
You must be superuser in order to run mrinfo.
EXAMPLES
The following example shows the output of the mrinfo command where mbone.phony.dom.net is specified as the multicast router: mrinfo
mbone.phony.dom.net 127.148.176.10 (mbone.phony.dom.net) [version 3.3]:
127.148.176.10 -> 0.0.0.0 (?) [1/1/querier]
127.148.176.10 -> 127.0.8.4 (mbone2.phony.dom.net) [1/45/tunnel]
127.148.176.10 -> 105.1.41.9 (momoney.com) [1/32/tunnel/down]
127.148.176.10 -> 143.192.152.119 (mbone.dipu.edu) [1/32/tunnel]
For each neighbor of the queried multicast router, the IP address of the queried router is displayed, followed by the IP address and name
of the neighbor. In square brackets, the metric (cost of connection) and the threshold (multicast ttl) are displayed. If the queried multi-
cast router has a newer version number, the type (tunnel, srcrt) and status (disabled, down) of the connection are displayed.
