Newly installed 6.1-RELEASE system with dummynet and hz=1000 built into the kernel. I ran this succession of commands: ipfw pipe 1 config bw 10Kbit/s ipfw add 00005 pipe 1 all from any to any Great. It works. Things are damned slow, which proves it is doing what I want it to. I also want to pass the packets through after the pipe to a few other ipfw rules, so I then did this: sysctl -w net.inet.ip.fw.one_pass=0 Everything still working great. Now, I want to just adjust the rate to the bandwidth I _really_ want, not 10 Kbit/s. So I run this command: ipfw pipe 1 config bw 10mbit/s Oops. After about 5 minutes, the prompt returns, so it's not like a normal accidental-ipfw-lockout (when those happen you never see the prompt again). But it might as well be, because that was the last response I got out of that system - can't ping it, can't connect, and both ssh sessions timed out trying to get a prompt back. So what did I do wrong ? I see that the man page calls for a uppercase M (10Mbits/s) whereas I typed a lowercase 'm'. Was that the problem ? Or was I supposed to remove the first pipe completely before reissuing the 'ipfw pipe 1 config' command again ? Any idea why that command took it off line ?
