It is probably not the normal thing that people would want to slow
down packets but I have to remote sites and have a few different
options for connecting them. There is no copper or fibre so I am
restricted to certain wireless and satellite systems.
I know what the latency of these proposed systems would be but I need
to make a realistic evaluation of the different systems in terms of
using our in house applications to test what latency would be
acceptable for users to actually work effectively.
Is there a way using iptables (or another linux method) that I can
create artificial latency by adding say 500 msecs to each packet
before it is forwarded?
Thanks and regards,
Abdul-Wahid

Hi,
Google for "netem and delay".
