sr-sprobe(1) sr-sprobe(1) sr-sprobe -Robust packet-pair bandwidth estimator
 

Summary: sr-sprobe(1) sr-sprobe(1)
NAME
sr-sprobe - Robust packet-pair bandwidth estimator
SYNOPSIS
sr-sprobe [-t] [-p] [-h]
DESCRIPTION
SProbe is a packet pair bandwidth estimation tool designed to be fast and reasonably accurate while mea-
suring to uncooperative hosts.
A novel feature of SProbe is that it would rather fail to give a response than present an errored one.
This is a scriptroute-based re-implementation of sprobe. It differs in that it does not use the TCP SYN flag,
and does not support "upstream" bandwidth measurement.
OPTIONS
-t Send TCP packets to port 80 of the remote server. Unlike vanilla sprobe, these TCP packets do
not carry the SYN flag.
-p Send ICMP "ping" packets instead. This may work well to NATs and firewalls that filter TCP
packets but respond to ICMP.
-h Show help.
EXIT STATUS
sr-sprobe exits 0 if it completes successfully, and 1 if out of order response traffic suggested that SProbe
should not even guess.
