I tried "questions" for this but no answer.
I am attempting to use ipfw and dummynet to instrument some network
traffic tests. I am running freebsd 4.3 release and have built the
kernel
with ipfirewall, dummynet, and default to enabled. For a simple test, I
added a pipe "ipfw add pipe 1 icmp from any to any". When I ping this
machine, I can do "ipfw pipe 1 show" and watch the counters increment,
but the machine doing the pinging does not see a response to the ping.
That's
my first question. Next, when I try to delete the pipe, "ipfw pipe 1
delete", it
won't delete. The only way I can get rid of it is to do a flush. That's
the second
question. Third question, if I type "ipfw pipe 1 config bw 10Bytes/s",
I would
expect the bw to be limited and the counters to reflect this limit. The
counters
indicate no change in the 64 byte/s generated by my windows client.
I have read the man pages for ipfw, dummynet, and ipfirewall. If these
are
obvious questions, I would appreciate a pointer to a good reference.
Thanks
