I was wondering if anyone was busy looking at implementing
TCP SACk (selective ack) on FreeBSD.
Thanks,
Geoff.

Back in the days of version 1.1, the tree was often broken in the
European / South African morning, which meant that a I was sometimes
doing patches before a make world would work again.
I think the maturity of the FreeBSD development process has changed
somewhat si
past the
initial problem. (Not the right thing to do, but it allowed me
to reboot without hitting single user mode.)

I just rebooted on an August 11 kernel. My system
still is happy with the disks. Hmm.
I can't remember exactly where my tracing went, before I
left off before, but the message you are seeing comes from
/sys/i386/isa/diskslice_machdep.c, line 200 (version 1.35).
What you will probably find, is
o portscan them.)
In default configuration, everything would behave as per
normal, and you would have to set a sysctl MIB before the
behaviour that I have described is displayed.
Can anyone think of any reason why this feature should
not be implemented?

Hmm, i would also look at something similar - rather generalise towards
countries that are crypto-unfriendly (like the USA, France, etc.)

I was just wondering if anyone has been experiencing problems with
TCP performance on -current -- my box built on 11 Sept is dog slow -
max 60kbps over 10baseT. I'm going to try and revert to an older
kernel and see if there is a difference.

My ethernet card is definitely running half duplex. Also,
as I mentioned, as a client, the box behaves fine, but not
as a server.

I intend to change my NIC. That will just take a little more time to arrange.

Apart from the comments in src/UPDATING,
Peter Wemm's ELF day web page, and Robert
Nordiers page on the new bootblocks, can anyone
think of anything I should take into account?

networks. (Not an easy one.)

having a quick look around - it would be a good idea to look at the
code which already exists in libstand (/usr/src/lib/libstand/bootp.c).
I haven't had an exhaustive look through the code, but this should
give the necessary material to work out another way of doing things.

Going into polled mode (lptcotnrol -p) is probably your best bet
at the moment.

The only significant diference is on Sequential block inputs and random
seeks where, notably the CU times have gone down. (I have taken no
account of other changes in the kernel.)

The same happened with the swap partition in question - a second
"swapon -a", and everything worked - that slice has however since
become my /tmp, as I already had enough swap.
I have only been getting "device not configured" errors on ad2 though.

I re-CVSuped this morning, and am now working again.
(Trust me not to enable crash dumps when I installed my system -
back in the old days, it was default)
Anyhow, I'm now waiting to catch the bastard when it falls!
