.SH "NAME"
tcpblast \- tool for measuring network bandwidth
.SH "SYNOPSIS"
\fBtcpblast\fR [options] \fIdestination[:port]\fR
.SH "DESCRIPTION"
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.
.PP
Destination can be name or address, IPv4 or IPv6. When IPv6 address is specified
with port it should look like: \*(L'[3ffe:8010::1]:9\*(R' (with single quotes to prevent
shell expansion of []).

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 \s-1KB\s0, \s-1MB\s0 or \s-1GB\s0. {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 \s-1RATE\s0 is in B/s or Bps, the postfixes can be [{k,m,g}]{b/s,bps}
  time (seconds):
    \-t and \-R \s-1TIME\s0 argument is in seconds, can be postfixed with
    [{k,m,g}]{s,min,h,w,m,y}
