netstress(1) utility designed to stress and benchmark network activity


netstress -m[NAME] | --master=[NAME] [OPTIONS]


Client/server utility designed to stress & benchmark network activity of a given ethernet device or path using simulated (random) real world data and packet sizes instead of fixed data and packet sizes.

Easily command line usage with random packets sizes and random data for read, write, or read & write (default) testing and reporting benchmark results from the ethernet device.


-m[NAME], --master[=NAME]
This instance is the master
-s[NAME], --slave[=NAME]
This instance is the slave
-h, --host nnn.nnn.nnn.nnn
Use this host or IP address
-p, --port nnn
Use this port (default=5678)
--seed, -S nnn
Use this random number seed (master only)
-c, --ctime
Report current time (default reports elapsed time)
-n, --nsec nnn
Report every nnn seconds (default=5)
-N, --nrep nnn
Benchmark every nnn reports (default=3)
-b, --bytes
Benchmark using bytes (default is bits)
-M, --mps
Benchmark using mbytes/sec or mbits/sec (default)
-K, --kps
Benchmark using kbytes/sec or kbits/sec
-B, --bps
Benchmark using bytes/sec or bits/sec
-w, --mwo
Only test master write / slave read
-r, --mro
Only test master read / slave write
-R, --realrandom
Do real random test (not pseudo random)
-f, --fast
Run Fast (no checking, no real_random)
-v, --verbosity
Enable verbosity (multiples increase level)
-d, --debug
Enable debugging (multiples increase level)
