The make buildworld failed because it was not able to find certain defines in the include files. This is no the first time I have encountered this. The work-around is to copy the include files to /usr/include and do the buildworld again. Sometimes you have to copy complete libraries to make it work. The canonical way to do this is to run 'make includes' from /usr/src. Incompatible changes do happen to -stable, I hate it when it happens too, but sometimes they are necessary.

Clock granularity, dummynet netperf
Hi, I'm trying to use the netperf benchmark to measure the throughput for a TCP connection whose propagation delay is controlled by dummynet. I'm running these experiments on FreeBSD 4.4 machines. According to my first results (even a simple ping shows it), the delays are not properly set by dummynet. Ok, the HZ option is set initially to 100. Following Luigi's recommendations, I've increased HZ to 1000. It turns out that I'm now getting segmentation faults when I run netperf! I've tried to play around with the quantum clock as well without success... I've increased it and the measurements get really wild, totally inconsistent. I've read Luigi's previous message about the impact on select() behavior on softwares that are not aware of this. So, considering that so many people have played around with the HZ option and could perform measurements without no problem, is there a patch to netperf that overcomes this problem or a better software for performance evaluation as good (or better) than netperf??? In case not, is anybody here familiar with this problem and has fixed it in the past? I would really appreciate any help, comments, etc. Thanks, Marcelo. __ Do You Yahoo!? Yahoo!

Subject: load balancing with 2 nic cards possible?
Is it possible to split the load of IP traffic with 2 ethernet cards on a
4.x machine? I'm new to load balancing in a sense, however, I'd like to
try something that seems more robust
The netgraph one2many framework allows you to aggregate 2 or 4 NICs together
even on an unmanaged switch. Obviously, this is only really beneficial if
the machine is serving several clients attached to the same switch or if
there is another machine set up similarly (also on the same switch), since
unmanaged switches generally only have one uplink port.
See the ng_one2many(4) manpage for details. Following is a script I use to
set this up (I call it from rc.local). fxp0 is the primary interface and
rl0 is the secondary.

Re: load balancing with 2 nic cards possible?
The FEC works for me doing the following on 4.5-STABLE: # cd /usr/src/sys # tar -zxvf path-to-download/fec.tar.gz # cd modules/netgrah/fec make install # kldload ng_fec.ko # ngctl mkpeer fec dummy fec # ngctl msg fec0: add_iface 'fxp0' # ngctl msg fec0: add_iface 'fxp1' # ngctl msg fec0: set_mode_inet then it usually needs a ifconfig fec0 up to start moving packets. Uplink is to a Cisco 3534 with the two ports setup with port group 1 distribution source, using distribution destination gives me countless duplicates obviously because the same mac-address is on both interfaces. I also added the mac-address to forward to both interfaces using mac-address-table static With this setup the max throughput from one remote machine is the capacity of one interface, but that is enaugh for me. /Oli Þann 27.
