mnathaniIf my quota limit says: 20000000
how many gigs is that?
[00:25]

brycecApparently 20MB?
mnathani: or just quota -s
(assuming GNU quota)
But yeah, quota uses bytes normally
[00:27]
mnathaniI think its in blocks
approx 10 gigs
@wa 20000000 blocks to gb

brycecblocks are somewhat arbitrary though
and usually abstracted beneath the FS
[01:26]
mnathanican anyone ping M.ROOT-SERVERS.NET [2001:dc3::35] (works from ARP, but not from my HE.net tunnel)
@smokeping
[01:26]
BryceBothttps://smokeping.cobryce.com/ [01:27]
brycecworks over my HE tunnel
And no I'm not hitting the root servers (yet) from my smokeping
[01:28]
mnathanithats wierd, I can ping it from the linux box that has the tunnel setup [01:28]
brycecmnathani: on ARP's backup system, "limit" is bytes (you have 20GB) and "blocks" are also bytes" [01:28]
mnathaniI should only have 10 GB though
thats what the portal says
[01:29]
brycecWell I have 20000000 and the portal says 20GB.
What's more, du says 8.5GB used, and quota says 8870132 blocks used.
so aside from a base-2/10 discrepency
, it's all kosher
at least for me
[01:29]
mnathaniMy du = 7.6G .
portal says 10GB
and quota is 20000000
probably a typo on up_the_irons part when provisioning
[01:31]
bryceccould be [01:31]
mnathaniI can ping 2001:4860:4860::8888 just fine
from my Windows 8.1 box that is routed via Linux to HE.net
but 2001:dc3::35
not able to ping
[01:36]
brycecbrycec blindly blames Windows [01:37]
mnathaniis there a different protocol
between the windows ping
and linux ping
not just my windows 8
I also have a centos behind the original linux box with the same behavior
[01:38]
brycecDoesn't one still use ICMP ping? [01:39]
gizmoguymnathani: what does a traceroute or mtr look like? [01:40]
brycecvs UDP ping? [01:40]
gizmoguyI'm thinking it's either a routing problem or an MTU problem [01:40]
mnathanihttp://pastebin.com/YiirLqmv
why would it work from the linux he.net tunnel box
[01:41]
gizmoguywhat does a traceroute from the linux he.net tunnel box look like out of interest? [01:42]
mnathanito m-root? [01:42]
gizmoguyyeah [01:42]
mnathaniits in the same pastebin [01:42]
gizmoguyjust to compare [01:42]
mnathaniat the bottom [01:42]
gizmoguylol
sorry
[01:42]
mnathaninp [01:42]
gizmoguyI didn't scroll my firefox window [01:42]
mnathaniI put a bunch of blank lines [01:43]
gizmoguyyup
well that's strange
[01:43]
mnathaniI would expect not to ping any ipv6
or all pingable ipv6
rather than ping most and not all
[01:43]
gizmoguyif you want to replicate windows's traceroute on linux
try "sudo traceroute -I M.ROOT-SERVERS.NET"
[01:44]
mnathaniI have another linux box behind
there is no traceroute command on windows
oh ok
I see
[01:44]
gizmoguythough I was pretty sure windows tracert used UDP
I wonder if it's an issue with source IP?
[01:44]
mnathanihow come other destinations like google and facebook come back [01:45]
gizmoguyare all your machines on the same /64?
true.
[01:45]
mnathanithey are
how do you source a ping from a different interface /ip on linux
[01:45]
brycec-I $IP, as I recall [01:46]
mnathaniconfirmed
its the source ip
http://pastebin.com/CcV0dxy7
[01:47]
gizmoguywoo 10 points to gizmoguy [01:48]
mnathaniping to google from he.net linux box sourced from /64 within routed /48
works, however same source to m-root fails
could there be a bogon
or source address filtering going on?
[01:48]
gizmoguyi'll try ping you from here
ping6 2001:470:b148::1
PING 2001:470:b148::1(2001:470:b148::1) 56 data bytes
From 2001:470:0:1b4::2 icmp_seq=1 Time exceeded: Hop limit
[01:49]
mnathaniFrom 2001:470:0:1b4::1 icmp_seq=1 Time exceeded: Hop limit [01:50]
gizmoguyyeah, i think you have some issues [01:50]
mnathanilol, I get the same thing
never thought of pinging from ARP before
[01:50]
gizmoguyhttp://pastebin.com/9FqhpmyN
so HE have a routing loop for your /64
[01:51]
mnathaniI could pick a different /64 [01:51]
gizmoguyoddly enough, this is the second routing loop in the past 10 mins i've helped solve [01:52]
mnathani2001:470:b148:0:1::1
thats in a different /64
?
my routed /48" 2001:470:b148::/48
[01:53]
gizmoguysame issue
it's probably an issue with the /48
[01:54]
mnathaniyea
I have a routed 64
as well
which I tried using, and that seems to work just fine
2001:470:1d:76e::1
2001:470:1d:76e::25
thanks gizmoguy :-)

m0undslate to the party, but windows traceroute = tracert, also you can get winmtr which is..well, you guessed it, mtr for windows. [06:48]
staticsafewinmtr doesn't do v6 :( [06:50]
m0undshasn't been updated in years either
my rust server has been invaded by korean, chinese and russian people
[06:51]
staticsafe:o [06:54]
m0undsi set up a log notifier that sends server connect/disconnect and chat stuff to an irc channel
every night, between 0000-1000, it's nothing but russian, chinese and korean chat
[06:54]
phluxWe're gowngrading to 1.5Mbps internet out of spite for the company we're currently with (only one other provider)
rip Netflix streaming
[06:55]
m0undscould just stream super ugly video at 500kbit/sec [06:56]
phluxI'll probably just move from streaming to DVDs/blurays and rip them as soon as they get here [06:56]
m0undsah, dlna streaming server or something?
mkv -> tv?
[06:57]
phluxyeah, via ps3 [06:57]
m0undsright on [06:57]
phluxtbh, I'm fine with 1.5Mbps until there's a larger market out here as long as I can still get on IRC :P [06:58]
m0undsare you in a rural area? or is your choice of providers just really shitty vs super shitty? [06:59]
phluxI'm in a new development on a military installation
There are only two companies that offer service out here so far. AT&T offers U-Verse one street away, so I'm hoping that comes our way soon
For now, we've been using this company called "CMA Access"
[06:59]
m0undsah [07:00]
phluxThey are expensive, and their staff won't believe me when I say problems are on their end
So I'm done with them
[07:00]
m0undsgross [07:01]
phluxI got into it with a customer service rep and decided "Fuck it"
Sooooooooo out of spite, we're moving to AT&T DSL until U-Verse is offered again
[07:01]
m0undshah [07:01]
phluxThankfully I already have DirecTV for my television needs
but I'm fairly certain I can live with it..my wife's parents live out in the sticks, and I'm pretty sure all they get is 1.5Mbps and it seems to work fine
OH, and CMA has a bandwidth limit where AT&T does not
so that's another plus
Of course, I won't be able to use too much bw only getting 150kb/s down :P
[07:01]
m0undshah
at least you're not stuck with satellite stuff
[07:04]
phluxVery true
tbh, as long as I can check e-mail, reddit, and IRC without having to restart my modem 500000 times a day, I'll be happier overall.
Plus I have a son due in April, and AT&T's price is only $24/mo
[07:05]
m0undswow, that's cheaper than a pots line here w/no additional svcs
also, congrats
april birthdays ftw
[07:08]
phluxthanks man [07:16]

ant21:09:36 <arpnetworks> [2e] We're investigating very high traffic (likely DoS) to host kvr24, also consuming resources in other [12:19]

maybe it wasn't a high pps attack
just high traffic

and that it was usually still few hosts
but yeah now with ntp reflection attacks..
any idea what kind of ddos it was?
[13:16]
m0undsi read something that 75% of the ntpds implicated in the attack on cloudflare have either been filtered or reconfigured [13:16]
mercutioi bet more of them have been filtered than reconfigured [13:17]
m0undsthat'd be my guess too
but at least the network ops are paying attention
haha

brycecYup, that was quite a chunk of disruption earlier. <obligatory smokeping graph: https://smokeping.cobryce.com/images/ARP/ARPWebsite_mini.png> [13:27]
m0undsugly [13:28]
mercutiothat looks milkd to me? [13:28]
m0undsi saw a ton of extra flow sessions open up w/my srx trying to reestablish the tunnel, til i took it down [13:29]
mercutiohttp://postimg.org/image/yd2ezgmhn/ [13:29]
m0undspretty funny
roughly....8 times as many as normal
[13:29]
mercutiomaybe i was just unlucky [13:31]
m0undsmy route to one IP is via SJC, and the other is straight to LAX - both nlayer. the LAX one was ~85% max pkt loss, the SJC one was 75.50% [13:31]
mercutioit looks like i was 95 to 100% packet loss
via ntt
[13:32]
m0undsthat's what i saw via ntt too (work uses centurylink -> ntt) [13:32]
mercutioso ntt went out harder [13:32]
m0undsyeah, seems that way at least [13:32]
mercutiojoy
does ntt have blackhole community?
[13:32]
m0undsthere was so much loss via ntt that i thought my vps had crashed or something at first because i wasn't getting any icmp replies whatsoever
it took almost 2 mins before i started seeing 1 or 2 here and there
[13:33]
mercutiolooks like it has standard 666
By default, peers are not configured for the blackhole functionality. Please contact the NTT NOC @ noc@us.ntt.net for this feature.
[13:33]
up_the_ironsmercutio: m0unds : i say filtered too. We filtered like 150 hosts. there's NO WAY one can just "wait" for the host admin to fix it [13:34]
m0undsyeah, for sure [13:34]
mercutioup_the_irons: lots of people are businesses etc
that may be able to fix themselves or filter
err lots of networks are businesses
still probably quicker to filter first
[13:34]
m0undsyup, as a reactive measure
and i guess preventative if there are systems that hadn't participated yet
[13:35]
up_the_ironsyeah but think about VMs here. lots may be businesses, but also lots are just home / hobby stuff [13:35]
mercutioi imagine most participated [13:36]
m0undsyep [13:36]
mercutioup_the_irons: but you're a provider to others
i mean if someone had their own network
[13:36]
up_the_ironsyeah [13:36]
mercutiontp being a problem all over the place [13:36]
up_the_ironsright [13:36]
mercutioif you have no control of course you're going to filter.
if you do have control you might or might not filter
upgrading ntp everywhere or fixing configs everywhere could be consdiered time-consuming
i wonder how big that ddos was
i've been hearing from a few various people getting hit by 10 gigabit+ ddos attacks recently
for small providers.
with less than 10 gigabit transit
it used to be considered reasonable safe for ddos attacks if you had 10 gigabit pipes or bigger
but it's probably shifting to 40 gigabit for safety or something now, which gets crazy if your average traffic is < 1 gigabit
[13:36]
brycecbrycec switches to 100mbps "If you can't take care of this Internet, you don't deserve to have good Internet." P [13:39]
m0undshahah
all your smokeping icmp traffic would clog the tuubs
[13:39]
mercutio100 people with 100 mergabit ddos is still 10 gigabit :/ [13:40]
m0undssave some internet for the rest of us
jeez
[13:40]
mercutioi can't type today
brycec: do you have any2ix/any2ix host?
on your smokeping
i'm curious what packet loss was like there
[13:40]
***iain has quit IRC (Remote host closed the connection) [13:42]
brycecI have no idea [13:44]
acf_http://kremvax.acfsys.net/smokeping.cgi?target=Remote.voipms-dnvrco [13:44]
m0undsouch [13:45]
mercutiothat's probably the normal ntt thing acf
just you're motiring ervery 5 minutes..
[13:45]
brycechttps://smokeping.cobryce.com/?target=Internet.VoipMS.denvervoipms
^ Mine for denver.voip.ms
(And I monitor every minute )
[13:46]
acf_20 pings every 2min [13:46]
mercutioif you look at his local thing he got heaps of gaps
it may be due to monitoring not completing in time?
it said 5 minutes acf?
well 300 seconds
[13:46]
acf_hmm ok [13:47]
mercutiomaybe you using a dns server outside network? [13:47]
acf_yeah, probably the DNS thing [13:50]
