Hallo,
ich habe auf einen Tip von hier vor einigen Tagen das Porgramm iperf
gesaugt. Der Rechner hat die Datei iperf3-3.1.3-amd64-freebsd10.txz
automatisch ausgeapckt und ein "Unix executable" draus gemacht. Wenn ich
nun im Terminal per cd Downloads in das Verzeichnis springe, wo das
Programm liegt kann ich es starten - allerdings bekomme ich
Mac-Mini:Downloads th$ ls i*
iperf3 iperf3-3.1.3-amd64-freebsd10.txz
Mac-Mini:Downloads th$ sudo iperf3 -c 192.168.2.100
Password:
sudo: iperf3: command not found
Mac-Mini:Downloads th$
Warum???
Wenn ich im Finder das Programm doppelklicke bekomme ich in eimen neuem
Fenster folgernde Ausgabe:

iperf3: parameter error - must either be a client (-c) or server (-s)
Usage: iperf [-s|-c host] [options]
iperf [-h|--help] [-v|--version]
Server or Client:
-p, --port # server port to listen on/connect to
-f, --format [kmgKMG] format to report: Kbits, Mbits, KBytes,
MBytes
-i, --interval # seconds between periodic bandwidth reports
-F, --file name xmit/recv the specified file
-B, --bind <host> bind to a specific interface
-V, --verbose more detailed output
-J, --json output in JSON format
--logfile f send output to a log file
-d, --debug emit debugging output
-v, --version show version information and quit
-h, --help show this message and quit
Server specific:
-s, --server run in server mode
-D, --daemon run the server as a daemon
-I, --pidfile file write PID file
-1, --one-off handle one client connection then exit
Client specific:
-c, --client <host> run in client mode, connecting to <host>
-u, --udp use UDP rather than TCP
-b, --bandwidth #[KMG][/#] target bandwidth in bits/sec (0 for
unlimited)
(default 1 Mbit/sec for UDP, unlimited for
TCP)
(optional slash and packet count for burst
mode)
-t, --time # time in seconds to transmit for (default 10
secs)
-n, --bytes #[KMG] number of bytes to transmit (instead of -t)
-k, --blockcount #[KMG] number of blocks (packets) to transmit
(instead of -t or -n)
-l, --len #[KMG] length of buffer to read or write
(default 128 KB for TCP, 8 KB for UDP)
--cport <port> bind to a specific client port (TCP and UDP,
default: ephemeral port)
-P, --parallel # number of parallel client streams to run
-R, --reverse run in reverse mode (server sends, client
receives)
-w, --window #[KMG] set window size / socket buffer size
-M, --set-mss # set TCP/SCTP maximum segment size (MTU - 40
bytes)
-N, --no-delay set TCP/SCTP no delay, disabling Nagle's
Algorithm
-4, --version4 only use IPv4
-6, --version6 only use IPv6
-S, --tos N set the IP 'type of service'
-Z, --zerocopy use a 'zero copy' method of sending data
-O, --omit N omit the first n seconds
-T, --title str prefix every output line with this string
--get-server-output get results from server
--udp-counters-64bit use 64-bit counters in UDP test packets
[KMG] indicates options that support a K/M/G suffix for kilo-, mega-, or
giga-

Also muß das Programm irgendwie lauffähig sein. Nur wie bekomme ich es
mit Parameterübergabe gestartet?
