Dear all,
I am currently experimenting with ipfw dummynet features (coming rather from
the netem tc corner; so being new to dummynet and apologise for these kind of
questions) and was wondering how to syntactically achieve build cascades of
pipes? listed on [1]?s front page. Unfortunately, I could not find a minimal
example for this in the documentation (or I missed the point).
Background: I am currently looking for concepts allowing me to put some
traffic into a pipe being followed by several queues, the scheduler and then
reinserted into another pipe (optimally as clean as possible). So, basically,
a cascade of pipes, optimally being able to consume from different other
pipes or interfaces. From the statement in [1], I assume ipfw + dummynet
could be the perfect playground for this, but from the syntax it was not
clear to me how this is done.
Any pointer to a minimal example or any reading recommendation would be
highly appreciated (maybe I have been searching the wrong channels so far).
Thanks in advance for reading and potentially commenting :)
the trick to enable cascades is to set the sysctl variable
net.inet.ip.fw.one_pass=0
(or equivalent in linux, /sys/modules/...)
so that packets coming out from a pipe re-enter the
firewall at the next rule.
cheers
