I have two networks connected via point-to-point T1 with a 1750 at each end. I want to measure maximum TCP throughput on the link for isolating a slow connection to a server across the WAN. I tried ttcp but the 1750 doesn't recognize the command to launch the transmitter. Is anyone aware of a freeware tool to send a large file to a windows machine on the other network and measure the amount of time it took to send the file? Thanks in advance.
