I wasn't even aware of it. I read the comments in
sys/netinet/tcp_vtw.c. Seems useful for systems that handle a lot of
sockets. Pretty neat.

Is there some reason why this is obsolete or something?

I think it's a notion invented to avoid offending people, by people
who themselves like to avoid confontation. Which masks facts and true
debate.

Respect for someone doesn't include agreeing with them. This is what
is missed in political correctness.

Yeah that's a step too far for me.

Preserving the fortune program as it is for historical context is fine
for me. Adding more quotes from this jerk isn't productive. That would
send the wrong message. People can find these quotes elsewhere.

In that sense I guess my position is preserving fortune as a
historical relic, nothing more. It's a snapshot in time of what the
developers of this stuff were thinking.

I was hoping some context of the fortune program would emerge from
this discussion. I'll try.

It's a snapshot in time of the mindset of people creating the
forefather of this operating system and programs. I, personally, love
it. It's a reminder that this project didn't start out of a stuffy
commercial setting, which is unfortunately what FreeBSD is becoming
(my opinion only). It was different than the big commercial programs
that were dominating computing at the time. And it still is.

I'm about 99% sure that these messages causing offense were not put
there to offend, but to remind. Possibly to remind the developers why
they were doing what they were doing. Someone said earlier that, to a
large extent, offense is taken, not given. I mostly agree.

If they (the quotes causing offense) need to go I'm not that bothered
because they will still exist elsewhere to remind us of the wrong way
to behave. I guess my question is, why shouldn't they exist here if
they exist elsewhere?

At the risk of not being politically correct, I agree.

The world seems intent on not remembering all history and even
changing parts of it to suit today's sensibilities. Which seems
dangerous to me. "All of it" (history) is "how we got here" and should
be learned from.

I'm not necessarily against removing stuff that is offensive to more
than a few people. But if there is value in remembering it to put it
into modern context, then we should think about it a bit.

Hello fellow moron :)

I have a general question:

I see some comments around unifying route caches, but in this
particular case it seems related to ipv6. Is this an ipv6 problem or a
general problem? I have a -current machine and it's not likely to
encounter this particular scenario (sorry, heh), but wondering anyway.

You don't need to configure it with ifconfig if you use hostap. Usually you
bridge it to your wired adapter and that adapter carries the address info.
Here is a hostapd.conf file that worked for me:

interface=urtwn0
ctrl_interface=/var/run/hostapd
ctrl_interface_group=0
ssid=NetBSD
macaddr_acl=0
auth_algs=1
wpa=2
wpa_psk=key
wpa_pairwise=TKIP CCMP

You generate the key with wpa_passphrase.

 Hello,
 today I've done a network install of netbsd-7/i386 (over http) and it was

 then choose configure network. Here things did start to go wrong:
 - I choose to configure wm0 with dhcp. dhcpcd did find the network
   parameters, including host and domain names. Then sysinst apparently
   decided to flush routes and remove the dhcp-configured address and
   network was not working after that. I had to do a static network config
   to get network working again
 - then, back to the http menu, I selected get distribution which did
   bring me back to the previous menu instead of downloading and installing
   sets. I had to go to the http menu again and select get distribution
   again to have it start the installation.

 Has anyone else noticed this ?


I noticed when I select get distribution (7.0_BETA for amd64) it would
take me back to the network config I believe.

Something is wrong but ultimately it didn't prevent an install so I didn't
follow up on it like I should have.

Re: dhcpcd ignores netmask from server, installs /8 or /24 instead

 I've been using NetBSD/sparc as a router/firewall for a long time.  My
 ADSL service provider uses DHCP for address assignment.  When I first
 started using ADSL, I was using ISC 'dhclient' and it worked quite well
 in exchange for having to do some fiddly bits in the /etc/ifconfig.xxx
 file.

 In the netbsd-6 era, with 'dhcpcd' being the default mechanism for a
 simple dhcp configuration line, I figured I'd give it a try for handling
 the upstream connection to my ISP.  It has required even more fiddly
 business to make it work than its alternative.  At present, using
 netbsd-7, the most vexing problem is as follows:

 Following an update and a reboot, 'dhcpcd' ignores the /20 netmask
 presented by the ISP's DHCP server and instead installs the address with
 a /8 netmask instead (the address assigned by the DHCP server would
 otherwise be a Class A were it not for the /20 netmask).

 This, naturally, cuts off vast swaths of T3h Intarw3bz (most notably
 Google) since my router then assumes they are on the same network and
 expects to get a response via ARP.

 Using '/etc/rc.d/network restart' gets things working again, but it's
 still not right.  The ISP's DHCP server again issues a /20 netmask,
 but this time, 'dhcpcd' installs a /24 netmask instead.  It installs
 a route to the /20 network along with the nearest /24 network.

 My ISP's upstream router is operating as a DHCP relay as the DHCP
 server is on an entirely different network from that presented by
 the upstream router.  Perhaps this causes confusion?

 My ISP seems to suffer prolonged outages of its upstream router, so
 when the lease expires, an IPv4LL/APIPA address is assigned and this
 also frequently has the wrong netmask (usually /24 instead of /16).

 I don't know if this is architecture-dependent or not.  Perhaps I'll
 copy my firewall rules over to one of my Soekris net4501s and see how
 it behaves on an i386 system in place of the sparc system.  (I have a
 local patch to work around kern/49124 for -7/-current.)


Have you tried dhclient lately? It's still there I think.

I didn't get the memo either.

This is not true in a relatively recent build of 6 when trying to

I didn't see a recent PR.

I'm wondering what is going on because I'm considering putting current
