	-h 
		Help
	-no 
		Disable logging to file. Logging to file is enabled by default.
	-o <filename>
		Name of log file. By default, following file names are used:
		Server mode: 'ethrs.log'
		Client mode: 'ethrc.log'
	-debug 
		Enable debug information in logging output.
	-4 
		Use only IP v4 version
	-6 
		Use only IP v6 version

In this mode, Ethr runs as a server, allowing multiple clients to run
performance tests against it.
	-s 
		Run in server mode.
	-ip <string>
		Bind to specified local IP address for TCP & UDP tests.
		This must be a valid IPv4 or IPv6 address.
		Default: <empty> - Any IP
	-port <number>
		Use specified port number for TCP & UDP tests.
		Default: 8888
	-ui 
		Show output in text UI.

In this mode, Ethr client can only talk to an Ethr server.
	-c <server>
		Run in client mode and connect to <server>.
		Server is specified using name, FQDN or IP address.
	-b <rate>
		Transmit only Bits per second (format: <num>[K | M | G])
		Only valid for Bandwidth tests. Default: 0 - Unlimited
		Examples: 100 (100bits/s), 1M (1Mbits/s).
	-cport <number>
		Use specified local port number in client for TCP & UDP tests.
		Default: 0 - Ephemeral Port
	-d <duration>
		Duration for the test (format: <num>[ms | s | m | h]
		0: Run forever
		Default: 10s
	-g <gap>
		Time interval between successive measurements (format: <num>[ms | s | m | h]
		Only valid for latency, ping and traceRoute tests.
		0: No gap
		Default: 1s
	-i <iterations>
		Number of round trip iterations for each latency measurement.
		Only valid for latency testing.
		Default: 1000
	-ip <string>
		Bind to specified local IP address for TCP & UDP tests.
		This must be a valid IPv4 or IPv6 address.
		Default: <empty> - Any IP
	-l <length>
		Length of buffer to use (format: <num>[KB | MB | GB])
		Only valid for Bandwidth tests. Max 1GB.
		Default: 16KB
	-n <number>
		Number of Parallel Sessions (and Threads).
		0: Equal to number of CPUs
		Default: 1
	-p <protocol>
		Protocol ("tcp", "udp", "http", "https", or "icmp")
		Default: tcp
	-port <number>
		Use specified port number for TCP & UDP tests.
		Default: 8888
	-r 
		For Bandwidth tests, send data from server to client.
	-t <test>
		Test to run ("b", "c", "p", "l", "cl" or "tr")
		b: Bandwidth
		c: Connections/s
		p: Packets/s
		l: Latency, Loss & Jitter
		pi: Ping Loss & Latency
		tr: TraceRoute
		mtr: MyTraceRoute with Loss & Latency
		Default: b - Bandwidth measurement.
	-tos 
		Specifies 8-bit value to use in IPv4 TOS field or IPv6 Traffic Class field.
	-w <number>
		Use specified number of iterations for warmup.
		Default: 1
	-T <string>
		Use the given title in log files for logging results.
		Default: <empty>		

In this mode, Ethr talks to a non-Ethr server. This mode supports only a
few types of measurements, such as Ping, Connections/s and TraceRoute.
	-x <destination>
		Run in external client mode and connect to <destination>.
		<destination> is specified in URL or Host:Port format.
		For URL, if port is not specified, it is assumed to be 80 for http and 443 for https.
		Example: For TCP - www.microsoft.com:443 or 10.1.0.4:22 or https://www.github.com
		         For ICMP - www.microsoft.com or 10.1.0.4
	-cport <number>
		Use specified local port number in client for TCP & UDP tests.
		Default: 0 - Ephemeral Port
	-d <duration>
		Duration for the test (format: <num>[ms | s | m | h]
		0: Run forever
		Default: 10s
	-g <gap>
		Time interval between successive measurements (format: <num>[ms | s | m | h]
		Only valid for latency, ping and traceRoute tests.
		0: No gap
		Default: 1s
	-ip <string>
		Bind to specified local IP address for TCP & UDP tests.
		This must be a valid IPv4 or IPv6 address.
		Default: <empty> - Any IP
	-n <number>
		Number of Parallel Sessions (and Threads).
		0: Equal to number of CPUs
		Default: 1
	-p <protocol>
		Protocol ("tcp", or "icmp")
		Default: tcp
	-t <test>
		Test to run ("c", "cl", or "tr")
		c: Connections/s
		pi: Ping Loss & Latency
		tr: TraceRoute
		mtr: MyTraceRoute with Loss & Latency
		Default: pi - Ping Loss & Latency.
	-tos 
		Specifies 8-bit value to use in IPv4 TOS field or IPv6 Traffic Class field.
	-w <number>
		Use specified number of iterations for warmup.
		Default: 1
	-T <string>
		Use the given title in log files for logging results.
		Default: <empty>
