Packet delay not respected in qscan.nse #1038
There is a defect in how script
The following patch remediates the issue. It also incidentally resolves #1037.
--- a/scripts/qscan.nse +++ b/scripts/qscan.nse @@ -484,12 +484,9 @@ -- Unlike qscan.cc which loops around while waiting for -- the delay, I just sleep here (depending on rtt) - if rtt < (3 * delay) / 2 then - if rtt < (delay / 2) then - stdnse.sleep(((delay / 2) + math.random(0, delay) - rtt)) - else - stdnse.sleep(math.random((3 * delay) / 2 - rtt)) - end + local sleep = delay * (0.5 + math.random()) - rtt / 1000000 + if sleep > 0 then + stdnse.sleep(sleep) end end end
Please let me know if you have any questions or concerns. Otherwise I will commit the patch in a few weeks.
