Danny, read the iperf man page: -b, --bandwidth n[KM] set target bandwidth to n bits/sec (default 1 Mbit/sec). This setting requires UDP (-u). The page needs updating, though. It should read "-b, --bandwidth n[KMG]. It also does NOT require -u. If you use -b, UDP is assumed. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
