Peter, I have just now had a chance to look at the nfsen.conf file as you recommended, and I'm not sure that I follow all of the steps I'm supposed to perform. It sounds like I need to create a separate instance of nfsen (can I just make a copy of the relevant directory hierarchy from my current install?) in which to run the simulation, with the data and configuration inserted into the live profile locations. I'm fairly confident I can do this, but unfortunately I do not have the disk space available to make a copy of the data - it's over 12TB and I only have about 9TB free on my flow collector. Would moving or symlinking the data temporarily work for this purpose? Ideally I need to find a way to do this without having to stop the live flow collection on my production nfsen installation. If this is possible, what would I need to do after the simulation completes in order to merge the freshly-graphed archive flow data back into my existing live profile? Thank you for your help with this, I think that nfsen could be a lot more useful for us if we can find a workable solution for graphing our imported nfdump flow data without impacting real-time collection :-) -- Robert Vineyard, CISSP, RHCE Senior Information Security Engineer Georgia Tech Office of Information Technology 404.385.6900 (office/cell) / 404.894.9548 (fax) ------------------------------------------------------------------------------ What Every C/C++ and Fortran developer Should Know!
