tcpblast - tool for measuring network bandwidth
tcpblast [options] destination[:port]
tcpblast/udpblast is a simple tool for probing network and estimating its throughput. By default it sends 300 blocks (1024 bytes each) of data to specified destination host.
Destination can be name or address, IPv4 or IPv6. When IPv6
address is specified with port it should look like: '[3ffe:8010::1]:9' (with
single quotes to prevent shell expansion of []).
Options
RATESPEC RATE[,TIME][:RATE[,TIME]]... RATE generating data at RATE
speed in B/s TIME for TIME seconds (can be floating point number), last can
be omitted and that time will be infinite
Options -b, -c, -R, -s and -t can use case insensitive unit
multipliers and specifiers:
size (bytes):
-b and -s argument without units is in bytes, can use [{k,m,g}]b (lower
or upper case) for KB, MB or GB. {k,m,g} are powers of 1024.
number:
-c argument is just a number, can have k, m or g added (powers of 1024),
no unit needed
rate (bytes pes second):
-R RATE is in B/s or Bps, the postfixes can be [{k,m,g}]{b/s,bps}
time (seconds):
-t and -R TIME argument is in seconds, can be postfixed with
[{k,m,g}]{s,min,h,w,m,y}
Example:
tcpblast -b 4KB -c 10k -R 10kbps,2:20kbps,3s target
tcpblast version: FreeBSD + rzm 20001030
