yeah it kinda seems broken. i can see the pipes being hit by traffic, but no bandwidth limitation is done whatsoever. I tried specifying dedicated port based pipes, that didn't work, I tried using queues for port specification while specifying pipes with the the same port numbers, that didn't work. I tried connecting pipes to the queues, no result as well.
for example, to limit outgoing ftp, I tried this,
${fwcmd} add pipe 6 tcp from ${oip} 21 to any out xmit ${oif}
${fwcmd} pipe 6 config bw $2Kbit/sno effect.
${fwcmd} add pipe 6 tcp from ${oip} 21 to any out xmit ${oif}
${fwcmd} pipe 6 config bw $2Kbit/s
${fwcmd} add queue 6 tcp from ${oip} 21 to any outno effect.
${fwcmd} add pipe 6 tcp from ${oip} 21 to any out xmit ${oif}
${fwcmd} pipe 6 config bw $2Kbit/s
${fwcmd} add queue 6 tcp from ${oip} 21 to any out
${fwcmd} queue 6 config pipe 6
setsockopt error.I guess it craps out when trying to bind queue to the pipe. Why ?? who knows.... I really can't make much sense from what I've read about dummynet in ipfw and dummynet man pages, if anyone knows of a good manual, please let me know.

Can someone tell me about a good way to troubleshoot pipes/queues or point me in the rigtt direction. I'm trying to restrict outgoing ftp traffic and create some pipes for VOIP. dummynet and pipe rules load fine ( and are in the kernel ) but seem to have no effect. I did read the manual pages 20 times over. I tried adding pipes before doing "config bw" on them, but that didn't make any difference.
thanx a lot in advance.
I have tried using DUMMYNET also and don't see any effect. If you find an answer, please let me know. It's my goal to give highest priority to ssh connection, next highest priority to the traffic originating on machine "bigdaddy" port 8080, and then all remaining traffic gets passed when there's nothing else going on. I have DSL with a 128K uplink. Here is my rule set in case someone can find my error:
# Flush before we define $fwcmd -f queue flush $fwcmd -f pipe flush
$fwcmd pipe 1 config queue 128Kbyte $fwcmd queue 1 config pipe 1 weight 85 queue 8Kbyte $fwcmd queue 2 config pipe 1 weight 1 queue 112Kbyte $fwcmd queue 3 config pipe 1 weight 100 queue 8Kbyte
$fwcmd add queue 1 ip from bigdaddy 8080 to any out via $oif $fwcmd add queue 3 ip from any 22 to any out via $oif $fwcmd add queue 2 ip from not bigdaddy not 8080 to any out via $oif $fwcmd add queue 2 ip from bigdaddy not 8080 to any out via $oif
And I have these options compiled into my kernel:
options IPFIREWALL options DUMMYNET options HZ=1000
Thanks,
Drew
