TCPRTT(8) System Manager's Manual TCPRTT(8) NAME tcprtt -- measure TCP handshake RTT using the stats(3) framework SYNOPSIS tcprtt [-f] host port DESCRIPTION The tcprtt utility reliably measures the TCP handshake round trip time us- ing the stats(3) statistics framework. Both IPv4 and IPv6 are supported. If the host argument is a hostname con- taining several A and AAAA records, one line per record will be printed. The options are as follows: -f Stop after the first address of each family For each address measured, a line is printed with 3 columns: address family (4 or 6), the numerical address and the measured RTT in milliseconds. When an error occurs for one of the measurement, the -errno(2) is printed in place of the RTT. If at least one entry returns an error, the command exits with the value of the last encountered error.
