good network troubleshooting tool

[Roger 'Rocky' Vetterberg]

Hi list,

Im looking for suggestions on a good tool to track down packetlosses.
MTR (/usr/ports/net/mtr) is exactly what I want with one exception: 
MTR uses ICMP, I would like something TCP based.
I have tried a lot of the utilities in ports but has so far not 
found anything that suits my needs. Does anyone have any suggestions 
on utilities or pointers where to look?

TIA
