Hi All,
I'm working on a minor modification to dummynet to create a pipe option
that allows arbitrarily specified packets to be dropped (as opposed to
the current "plr" option that introduces random, uncontrollable packet
loss). I can't seem to figure out how to clear/reset dummynet queue
counters associated with a pipe, which are shown when "ipfw pipe list"
is issued.
Example of counters I'm referring to:
... Tot_pkt/bytes Pkt/Byte Drp
... 2619 219996 0 0 4
^^^^ ^^^^^^ ^ ^ ^
The ipfw man page and source does not reveal anything obvious, and in
fact indicates to me that the functionality does not exist at all. Yes,
I can delete and recreate the pipe which has the same net effect, but
it's not as useful as, say, a "ipfw pipe zero" option. It's entirely
possible I've missed something though so I wanted to check before diving
in and attempting to add support for this.
Cheers,
Lawrence
