WhoWhatWhen
acf_"However, a critical detail was overlooked in that backbone provider GTT/nLayer was doing the majority of the heavy lifting for CloudFlare." [00:00]
mercutio(usually you'll hit a peered connection when browsing hosted sites)
yeah but i see ntt :)
maybe ntt do flowspec now
[00:00]
acf_so GTT was integral to the CloudFlare implementation at one point [00:00]
BryceBotTO THE CLOUD!!! [00:00]
acf_that's interesting [00:00]
mercutiohttps://njetwork.wordpress.com/2013/04/30/mitigating-ddos-attacks-with-bgp-flow-specification/
The specification was written by guys from Cisco, Juniper, Arbor Networks and NTT America, but only Juniper implements it at the time of writing.
so yeah maybe ntt are implementing it now
but yeah now they're not, and they're hosting on cloudflare, and they can't handle ddos??
that anti ddos protection crap at the beginning is like soimething to enable when you're under active ddos attack to try and reduce traffic
[00:01]
acf_that seems like it would be expensive to implement on all of your network's routers
if you're NTT and you have a bunch of customers
and you have to deal with all of their firewall rules
like rate limiting individual traffic streams?
seems like that has to be stateful, for each stream
> then rate-limit 1m;
[00:06]
mercutioi have never looked into it tbh [00:07]
...... (idle for 27mn)
:666 blackhole stops most ddos attacks.
err blackhole community, it is noramlly called 666 as that's the community number standard :)

grodymy isp has an extremely effective ddos detection
as soon as they see traffic being sent down your line faster than it is connected, they simply sever you (they also have means to filter certain types of dos too)
realisticly end users can only hope for that, at least if i get shunted offline i can log into their panels and see why im offline
after much playing (and subtle hair loss) - i have found my solution - debian & xen
hyper-v is nice n all, quite fast for freebsd guests - but no way of vga passthru on my system by looks
just need to get a way for debian to give me an option to go full X and only run the background guests (that need no head), or to choose windows passthru & background guests and leave the host idle for ssh
[14:25]
acf_the Level3 trunk is acting strange [14:36]
mercutiogrody: have you tired that alternative to vnc
uhh spice
[14:42]
grodyhave been reading about that [14:45]
mercutioit's a lot nicer [14:45]
grodyhave been using the sdl interface vs vnc [14:45]
mercutioahh ok i haven't palyed with that [14:45]
grodyit's faster in general, but if you lose that window, you kill the vm [14:46]
mercutiospice is fast over lan
i can't remember what it's like over internet
[14:46]
grodyahh i'll be running everything locally [14:46]
mercutiowell it's still worth a shot
by fast i mean web browsing on windows was good from linux :)
like scrollign was good even
[14:47]
for some reason most remote video still scrolls terribly [14:52]
RandalSchwartzI did it! I hacked my first fbsd ports Makefile!
p5-Business-ISBM required a newer ExtUtils::Makemaker, so I added that to my BUILD_DEPENDS
RandalSchwartz does a happydance
now to submit that patch back upstream
[15:01]
mercutioi had heaps of problems with freebsd ports back when i used freebsd as a desktop :/
it seemed that any given time lots of things were out of sync
there was no stable branch?
i haven't had any issues recently with much less ports used though
but they always seem to change dependencys around for versions
mind you that was mostly with things like gnome etc
[15:03]
RandalSchwartzstable what? [15:05]
mercutiolike when doing cvs upgrade on the ports tree [15:05]
RandalSchwartzwell - it claims it needs perl 5.18, which probably has the required module in core [15:06]
mercutioyou don't have release tagged versions, it just constantly updates. [15:06]
RandalSchwartzEUMM is one of those "dual-tagged" modules
both a core version, and a version in CPAN
I'm still running 5.16, so I had to "upgrade" my EUMM
but poudriere always starts with a clean slate
this is the first time that has been a problem. :)
I built EUMM 7.04, and that's what's installed on my host machine
but poudriere used the 5.16 perl stock EUMM, and p5-Business-ISBN hated that
[15:06]
mercutiohmm
i think i have perl 5.20
well on linux
i've got no idea what perl has been changing in their new versions
[15:09]
RandalSchwartzperldoc perldelta :) [15:09]
..... (idle for 21mn)
mercutioahh i have 5.20.2
lots of little things?
Errno has been upgraded from version 1.20_03 to 1.20_05.
that means nothing to me for instance
[15:30]
RandalSchwartzit means nothing to me either. :)
it probably means they fixed some bugs.
the perldelta has a lot of insignificant noise.
[15:35]
..... (idle for 21mn)
mercutioit seems to be mostly language and unicode improvements
err and fixes
[15:56]
RandalSchwartzwhat does a freebsd ABI look like?
as in, in pkg.conf, ${ABI}
ahh... like this: freebsd:8:x86:64
[16:05]
I should name my poudriere jails like that too then
hmm. that doesn't look like anything in uname -a
I wonder how you get the ABI
I could look at the source of pkg, I guess... since it parses pkg.conf with that var
Oh... geez. pkg gets it literally by reading the elf info from /bin/sh
pkg query '%o %q' can show you the same ABI string too

RandalSchwartzthere we go
the "other" auckland :)
[18:49]
mercutiothe other? [18:57]
RandalSchwartzyes... there's a story of a person getting on a flight at SFO, heading for what he though was "oakland". Turns out, it was a flight to auckland.
... http://articles.latimes.com/1985-04-11/local/me-11793_1_auckland
[18:58]
JC_Dentonlol [19:02]
***Hien has quit IRC (Remote host closed the connection) [19:02]
JC_Dentonlong flight difference [19:02]
RandalSchwartzyeah - I think he was wondering why he wasn't down in an hour or so [19:02]
JC_Dentonand why would you fly from SFO to OAK?
that has to be like the dumbest flight ever
[19:02]
RandalSchwartzspeaking of oakland, I had to pick up my girlfriend once at OAK and her flight was "alaska 404". I was wondering if I would see "flight not found" [19:03]
JC_Dentoni actually discovered OAK recently and quite like it [19:03]
mercutiorandal: don't they separate international and domestic terminals there? [19:03]
RandalSchwartzapparently this was 1985
probably more ways to make mistakes :)
US doesn't have any exit customs
so it could have been all from same terminal
[19:03]
mercutiojc: don't people regularly fly between los angeles and san francisco?
i don't know where oakland is though
oh it's one bridge away
[19:04]
RandalSchwartzOh... might have been originated in Sac [19:05]
mercutio23 minutes by car apparently
where's santa clara hmm
[19:05]
RandalSchwartzmore details - http://articles.latimes.com/1985-04-03/local/me-28522_1_europe-vacation [19:05]
mercutiooh santa clara is a bit further away [19:06]
grodygrody somehow ended up installing windows 10 TP to play with [19:06]
RandalSchwartzAhhh yeah, from LAX
either to auckland or oakland
[19:06]
mercutiogrody: i have windows 10. what do you think? [19:06]
RandalSchwartzand he was still in internatil [19:06]
grodynot bah
bad*
it's pretty damned fast on this thing too
[19:06]
mercutiogrody: windows 10 feels faster than windows 2008 did to me
but it's got a few annoying bugs.
like it keeps wanting me to do an update, but there's no update, and i have to click postpone.
[19:06]
grodynot had that [19:07]
mercutiobut like if playing a game or something, it'll pop up taking over :/
i didn't used to have it, it started at some point
also it boots into this thing saying whether you want to roll back every boot
this was "upgraded" to build 9926
[19:07]
grodyjust finished playing with miracast [19:08]
mercutioi dunno if that makes any diff
also they keep updating the amd video drivers recently, and the most recent ones seem buggy
[19:08]
grodyswmbo was watching TV, then i just took it over with IE on youtube [19:08]
mercutioand i have to unplug/replug my monitor to a different slot sometimes
or the secreen is all garbled.
[19:08]
grodyah i installed the ones off AMD site [19:08]
mercutioso yeah a few annoying issues, but nothing corrupting data or anything [19:09]
grodydidnt find 2D was all that [19:09]
mercutioreally? [19:09]
grodyplus a few windows 8 drivers for a few other specifics which has gotten everything working [19:09]
mercutioi'm pretty sure they're including the real amd drivers now. [19:09]
grodyi think so, but was no opencl :> [19:09]
mercutiooh [19:09]
***djkrikke-2 has joined #arpnetworks [19:10]
mercutioi don't know what programs use opencl
i found some opencl test which didn't work on linux
but it all seemed rather complicated.
[19:10]
grodyit also allows swapping to video ram in some scenarios
boinc uses it too
[19:10]
mercutioi don't know that program
i was kind of hoping more things would be accelerated by now
my amd cpu is so much slower than g3258
[19:11]
grodyaye, i have seen some databases being offloaded [19:13]
mercutiooh? [19:13]
grodybut would have hoped to shunt a virtual machine or most of it's load off on it [19:13]
mercutioi think amd's lack of memory bandwidth and high latency kind of hurt
like the g3258 has way faster memory speed
for the same clock rate
[19:13]
grodyhttp://highscalability.com/scaling-postgresql-using-cuda
there are some apps in debian & mint that are poc of similar
[19:15]
mercutiooh curious.
i got that library thingy for doing stuff going
for amd's hybrid mode or whtaever thing they call it
hsa?
the demo thing ran
but i couldn't find anything useful to run with it
[19:16]
grodyhm
grub will boot linux in secondary partitions, right?
[19:17]
mercutioi think so, i use uefi [19:17]
grodyfbsd in primary (with secondaries in container), windows in another primary, debiab in another with LVM then a few small to tinker with in secondaries off the last space for primary
this bios/efi is weird.. it's a bios, but supports secure boot and a uefi console, but noting fancy
freebsd's uefi boot barfs the screen like esxi does
so far only archlinux seems to utilize the uefi boot (as does windows) properly
see how long it is until i break this...

brycec(grub can boot linux on any mbr or gpt partition, provided the bios can boot to grub at least -- grub installed to the mbr, or first partition typically)

***ix33 has joined #arpnetworks [21:02]
brycecArch offers grub2, but since Arch is very much a "build it however you like" distro, I wouldn't say it necessarily uses any one thing.
(for instance, Arch provides directions on booting a kernel EFI stub directly, or using any other bootloader)
[21:07]
mercutioyeah, i've been meaning to try efi stubs directly
or at least consider something other than grub
