Re[2]: Is it possible to slow down the network interface?
--- Original message --- From: Jason Hellenthal jhellent...@dataix.net Date: 3 April 2013, 03:16:11 Bandwidth limiting via pf or ipfw ? IPFW for this task is the best choice since PF has ALTQ which is 1990s technology. For the experimental/testing tasks IPFW has another advantage: this is possibility use as bandwidth limitation as well as delay. ___ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to freebsd-net-unsubscr...@freebsd.org
Is it possible to slow down the network interface?
For the testing purposes, I would like to be able to control the maximum speed of the interface. There is this command 'ifconfig re0 media 10baseT/UTP' that is supposed to lower the speed to 10Mbps. However, it makes interface unusable on my system. All connections are broken, even the router had to be rebooted. Maybe this is the router issue. Is there any other, soft way to change maximum interface speed to a particular value? When somebody sends data too fast, OS sends back ICMP notifications that connection is jammed. My question is, is it possible to impose such condition artificially? Is 'ifconfig re0 media 10baseT/UTP' actually supposed to work transparently, or disconnects are to be expected?

There are man pages describing all of the above and should be a good starting place for you. ~Paul This message may contain confidential or privileged information.

Re: Is it possible to slow down the network interface?
Bandwidth limiting via pf or ipfw ? ipfw may be more forward to use since its usually easier to comprehend the syntax and type it directly on the command line. -- Jason Hellenthal JJH448-ARIN - (2^(N-1)) On Apr 2, 2013, at 19:25, Yuri y...@rawbw.com wrote: For the testing purposes, I would like to be able to control the maximum speed of the interface.
