1/19    What is the easiest way to figure out how much data is going over
        an interface/interfaces to another set_of_interfaces/interface?
        (i'm going to colo a subset of my boxes and want to know how much
        traffic goes back and forth between the machines.)
        \_ Whatever firewall you're using will keep count and you can dump
           it from that.  Instructions vary by firewall, naturally.  If you
           just want momentary numbers, trafshow is very handy.
           --dbushong
           \_ a lot of this traffic now is on the same logical/physical
              network so there is no firewalling involved.
              \- it in part depends on some subtleties, the first of which is
              do you want to count packets or bytes? do you want to distinguish
              between vifs or real real interfaces? if WAN, asymetric routing
              is a factor. How are you going to count lost packets, retrasmits
              etc. if my answers frighten you, perhaps you should cease asking
              scary questions. --psb

              \_ psb, why don't you ever indent your entries. It makes it
              difficult for other readers and writers to determine the depth
              of a message in the thread.
                \_ The psb shall do as the psb pleases, peon!  --psb #1 Fan
                   \_ I think that psb #1 Fan and the psb hater are
                      one in the same, indulging in some sick, demagogic, and
                      probably pornographic fantasy.

7/20    Do people not know that the only place where there is no speed
        limit is on a freeway onramp?  Which means that it is the entrant
        driver's job to speed up and get in past the existing traffic?
        \_ The ones who can't accelerate are in SUVs
           \_ True.  My 2nd-gen Prius (not the 2010) accelerates on the
              on-ramps fine.  -- !OP
