Hello, I am trying to help a customer track down where the bottlenecks are in his WAN. The problem is that the main firewall, as well as other key points in the WAN structure are NT servers, which I don't have the complete access to. (OK, please don't tell me *those* NT boxes are the bottlenecks -- both the customer and I know well that NT might not have been the wisest choice when the WAN was built three years ago, but that's the way it is and things aren't going to change overnight...). Last year I slowly began introducing FreeBSD boxes for mail and database management tasks, with excellent results so far. Now, my question is: Are there any tools that might be useful to take timings of the WAN from a FreeBSD 4.1-RELEASE system that sits behind the firewall? I'm thinking about something that could show how much time it takes for a packet to reach a given point from the FreeBSD box. traceroute perhaps? But how could I then plot the results in a meaningful way, i.e. that will help us improve the WAN topology, as far as technically possible. Thanks to everybody in advance for any pointer.
