Why does it hate freedom?!

it's not the bot
it's wunderground changing their response without informing developers

i'm surprised the weather shows so cold here.
it feels hot :)

definitely about that cold here :D

that said it's only the morning
wow
huge diff :)

my room is already 26c
for inside i find 28c feels hot.

brycec

I'm sitting in a comfortable 20C

mercutio

most people run air conditioning at 23 to 24c.
mercutio has no air conditioning
yeah i reckon 20c is better for doing stuff normally :)

brycec

My AC is "open the window" which currently would let in snow, undesirable :p

[13:20]

mike-burns

20C is the temperature of our skin, IIRC.

[13:20]

20c is pretty common for data centres..

mercutio

it doesn't really need to be that cold, but if air conditioning fails it gives more time to recover

mike-burns

OK now @weather hates Europe.

Boom.

brycec

mercutio: Plenty of computers and monitors keep my place plenty warm, plus good insulation and insulative windows.

mercutio

Brycec: any idea how hot rooms are normalyl that you're not in?
yeah, when i used to live in colder city i had bad insulation
which was typical.

brycec

Not sure what you're asking, mercutio

[13:23]

mercutio

and it could get down to like 8 or 9 c
brycec: like my kitchen would be cold :/
because not in there.
and no double glazing, and not a good seal on windows, doors etc, and no heater in there..
but you go to a room you're using and it's like 20c or whatever

[13:23]

brycec

Ah. Hard to say because my fiancee won't let me keep the heat off. Currently though, it's around 18-19 without the heat having run for a couple of days.
(Bedroom)

[13:24]

mercutio

oh, central heating?

[13:24]

brycec

No, baseboard electric heaters. (which are awful)

[13:24]

mercutio

i was more meaning what it was like in maybe rooms you don't use as much so don't heat.

[13:25]

brycec

There are 4 "rooms" - bedroom, office, bathroom, living room. Not a lot of unused space.

[13:25]

mercutio

oh apartment?

[13:26]

brycec

Yeah

[13:26]

mercutio

yeah that may make it easier.

you're in stockholm mike-burns ?

[13:28]

mike-burns

Yup.

[13:29]

mercutio

and you want to pack your swimming trunks? :)
oh! because you're going somewhere hot :)

[13:29]

mike-burns

Right yeah. I'm packing!
I'm already in Stockholm.
But apparently I'm going to a place that is 7C. 1 degree warmer!

[13:29]

mercutio

damn
well there's optimism :)
damn stockholm weather seems to vary btewen 6 and 9 c

[13:30]

mike-burns

Global warming.

[13:31]

mercutio

ok that's just bizare, 9c at 2 am is warmest time of day?

[13:31]

mike-burns

Ha. I can't explain that one.
The sun is mostly set at this time of year, so I guess the weather just does what it wants.

[13:31]

mercutio

sunset at 3 pm?

[13:33]

brycec

brycec assumes cloud cover is involved

[13:33]

mercutio

brycec: that'd make sense

[13:33]

brycec

I always hated cloudy days+nights where I grew up because it meant the next day would be even hotter - the clouds served as a blanket and didn't allow the heat to escape overnight.

[13:34]

mercutio

ahh
my old city had taht problem with pollution
ie winter problem rather than summer problem
not made better by people with fires etc

[13:35]

brycec

Yeah we had pollution and no-burn days/nights too. but that was less of a day-to-day problem, just ongoing stuff. the clouds/heat thing was noticeable day to day.

mnathani_

its that time of year again and I am looking out for a deal on a wild card SSL. Any suggestions?

[15:41]

mercutio

it's cheaper to buy many non-wildcard unless you need a lot of subdomains.
that free ssl thing is in open beta now
i haven't tried it yet
normally i buy certs from namecheap, because they're cheap
but positivessl seems to be $94/year there
where non wildcard is $9/year
so even if you want 6 domains or such, it's cheaper to buy many, and it's arguably more secure.
in that if one gets compromised they don't all get compromised. (but if you're running everything on one server it doesn't make so much difference, and it may make it more likely that you leave files in insecure directory or such)

[15:45]

......................................... (idle for 3h22mn)

mnathani_

mercutio: yea 1 server at the moment

[19:10]

mercutio

well you have to ask yourself if you really need that many domain names :)
i suppose it's "easier"
than managing multiple certs.

[19:14]

mnathani_

over time I would be adding additional subdomains, not to mention the ones already configured with my existing wildcard ssl. And it is easier to manage a single cert for all subdomains.

yo
was wondering if there was something that had to be set up on arp's end for the /48 & fe80::/64 routing to take place
I setup my interface but then set an ip address on another interface and it didn't work
guess I could look at some packet caps but this seemed to work seemless last time and my account was off for awhile

[19:50]

brycec

Yes there is.
Normally ARP provides your gateway as a 2000:/3 address, but if you're getting a /48 from ARP, your gateway is a link-local fe80:: address
http://support.arpnetworks.com/kb/main/what-is-the-difference-between-my-ipv6-64-assigned-space-and-48-allocated-space

[19:52]

erratic

yeah I found that, I used to have this setup now I can't figure it out anymore xD
I assigned fe80::/64 to eth0
then 2607:f2f8:a2c4:f00f::1/64 to a GRE tunnel I setup..

[19:56]

brycec

If this is a new account/address block than before, they're going to have to setup their end before it'll work for you...

[19:58]

erratic

it should be the same, the only thing is I let my account go inactive for a couple of months like I think it went inactive in july then I logged in and set it back up late last month
and my /28 is still routed it seems
oh hmm maybe its not
wait yeah it is.
yeah so the agg is prob still in the table
unless they took it out for some reason but left the ipv4 agg

[19:59]

mercutio

erratic: send a ticket in if you want to check.
you should be able to ping6 fe80::1 though
if you're routing between interfaces you probably have to have forwarding enabled too

[20:08]

erratic

yeah
fe80::/64 dev eth0 proto kernel metric 256

[20:14]

mercutio

can you ping fe80::1 ?

[20:18]

brycec

I think that should be fe80::2/64, btw

[20:18]

erratic

gw-208-79-92-66 ~ # ping6 fe80::1
connect: Invalid argument
gw-208-79-92-66 ~ # ping6 fe80::1/64
unknown host

[20:18]

brycec

well duh, it's a link-local, gotta ping6 fe80::1%$interface

erratic

brycec

eg: PING fe80::1%eth0(fe80::1) 56 data bytes
64 bytes from fe80::1: icmp_seq=1 ttl=64 time=0.464 ms

erratic

yes, I can ping it

brycec

erratic: fix your interface IP 20:15:20 brycec | I think that should be fe80::2/64, btw

[20:20]

erratic

sorry about that :S thanks for showing me that though :)

[20:20]

brycec

fe80::1 is routing traffic to fe80::2, not fe80::

[20:20]

erratic

inet6 fe80::2/64 scope link on eth0?

[20:23]

mercutio

i've been tracing you and 'm not even getting a response back from your vm it seems
let alone the other end of gre tunnel.

[20:25]

erratic

looking at a packet dump when I ping6 fe80::1%eth0 I am seeing 2607:f2f8:add0::2 > 2607:f2f8:a2c4:f00f::1: [icmp6 sum ok] ICMP6, echo request, seq 59012
yeah the other end isnt setup yet you should be able to ping6 2607:f2f8:a2c4:f00f::1: though presumably
minus the trailing :..

[20:27]

mercutio

hah that's the ping i left running erratic
mercutio stopped it for you
you did enable forwarding right?
and judging by eth0 you're using linux. so check iptables FORWAD table too
s/FORWAD/FORWARD/

[20:28]

BryceBot

<mercutio> and judging by eth0 you're using linux. so check iptables FORWARD table too

[20:32]

erratic

yep default policy accept and net.ipv{4,6}.forwarding = 1
I might have to try tearing down the gre tunnel
and seeinf I can get it to work some how

[20:33]

mercutio

make that ipv6tables
err ip6tables
ip6tables -vL -n
and check forward policy is accept, or has rules to allow traffic through
if the gre tunnel is working, you can try running a trace through it, and then tcpdump on the external interface to make sure it's going out
also if you're routing your ipv6 traffic back out again from the tunnel you probably have to route it it back via the tunnel or your isp will drop it. (or your isp may not even have ipv6)

then here on my end of the tunnel just ip -6 route add 2000::/3 via 2607:f2f8:a2c4:f00f::1 dev sylmar0
thanks for the help guys :)
actually helps more than you know this is good stuff to know

[21:08]

mercutio

you have no default route?
was that your issue?
it's kind of werid how you can default route with just 2000::/3 when used to ipv4

[21:13]

brycec

I for one love that public unicast can be expressed so simply :D
unlike ipv4 with its interspersed RFC1918

[21:19]

mercutio

yeah i'm starting to like ipv6

Im curious to ask what is arp using for .. I guess layer 2/3
just 802.1q?
or vxlan or something
I just read about vxlan I was wondering myself, I dont get to wonder about things like that too often though unfortunately

[22:46]

brycec

vxlan != vlans
for layer 1 ARP has copper plugged into switches (except for fibre interlinks). On top of that are VLANs, 1 per customer. Nothing fancy.
ARP will need to look into better scalability such as using vxland, but right now it's pure 802.1q

[22:49]

mnathani_

s/vxland/vxlan

BryceBot

<brycec> ARP will need to look into better scalability such as using vxlan, but right now it's pure 802.1q

brycec

heh

erratic

well 1001 vlans per trunk termination thats like... a lot of hosts for a single host I would imagine..

brycec

brycec is reaching over things to type, always makes for fun typos
"a lot of hosts for a single host" I have no idea what you mean
(nor how you arrived at 1001 as a number)

[22:54]

mnathani_

cisco switches go up 4000+ vlans if I remember correctly

erratic

untagged

brycec

why would anything be untagged????!!

erratic

trunks carry up to 1001
