Server badwidth consumption

[Steve Davidson]

Hello BSDers,
I am working for a new company that has a server running SCO (Unix flavor I
haven't encountered b4) and I need to measure the traffic flow in and out of
this box. Is there a way to do this without a) messing with the SCO box or
configuration or b) installing a bridge between the server and the network.
I am running FreeBSD 6.1 on my desktop. Any advice would be much
appreciated. Thanks.
