As in: NAME ttcp - test TCP and UDP performance SYNOPSIS ttcp -t [-lbuflen] [-s] [-nnumbufs] [-pport] [-u] [-D] [-L] [-Aalign] [-Ooffset] [-v] host [out] DESCRIPTION Ttcp times the transmission and reception of data between two systems using the UDP or TCP protocols. It differs from common "blast" tests, which tend to measure the remote inetd as much as the network performance, and which usually do not allow measurements at the remote end of a UDP transmission. It's extremely useful. Steinar Haug, Nethelp consulting, sthaug@nethelp.no To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
