Hello,
I've been trying to wrap my head around the differences between address
resolution in IPv6 and IPv4 and I'm a bit confused by a real-world issue
I'm seeing in a colo facility where we have dual-stack connectivity.
Basically, what I see is summed up in this recent post:

though,
but info on the guts of address resolution was hard to come by.
It would be really great if the network_ipv6 script would toggle the
link-local sysctl when run. Why it does not puzzles me.
Thanks,
Charles

Hello,
We're running a few 8.1-R servers with Broadcom bce interfaces (Dell R510)
and I'm seeing occasional packet loss on them (enough that it trips nagios
now and then). Cabling seems fine as neither the switch nor the sysctl
info for the device show any errors/collisions/etc, however there

Hello,
I've run into an odd problem on an 8.1 amd64 box (still running GENERIC)
with aliases on the em interface.
Config is very simple:
em0: flags=8843 metric 0 mtu 1500
options=9b
ether 00:14:22:b1:54:18
inet 10.3.2.233 netmask 0xff00 broadcast 10.3.2.255
Following up on my own post...
Well, that was dumb. I had IPMI enabled, and it had the same IP I was
trying to use for the alias. Had no idea it somehow created it's own MAC
though, that's odd.
Sorry for the noise.

I'm having trouble finding the canonical answer on two uses of

First, the easy one. For IPv6 aliases, what is the proper subnet? I've

Normally it is a /64. See also Section 2.5.4 in RFC 4291.
My understanding was that a /64 was a common subnet since it's the minimum
size

How about attaching that to one of the PRs open on this bug? Maybe
someone will commit it then...

Howdy,
Sorry to bring what seems like a simple issue up here. I had been blaming
slow afp filesharing between my OS-X (10.3.8 and previous) and FreeBSD 4.x
boxes on netatalk's afp implementation for some time. Not too long ago I
got frustrated with this and tried smb and then ftp. On a simple
