Anyone else?

Might not have been network, my VPS' loadavg hit at least 30 according to munin once things came back. [14:17]
mercutiowhat host? [14:30]
bryceckvr21
from about 13:45-14:00 ARP time
my VPS became unresponsive (syncthing even claimed "Paused state detected, possibly woke up from standby."), then when it came back it got slammed and triggered its OOM killer too
I'm still poking through my logs to figure out what happened
No reboot or anything at least.
Looking at my smokeping slave access logs (the slaves connecting to the master which is this VPS), it looks like there were a handful of missed check-ins. There should be several every 60 seconds, but in that period, at least 1/3 are missing. Packet loss maybe? :/
Looking like it was isolated to ipv6 connections?
[14:33]
mercutiochecking disk situation first [14:38]
brycecCool. I'm not finding much in the way of definitive evidence of what exactly happened (I wasn't paying attention at the time either) :/ [14:39]

mnathani_lol [20:16]
mercutioit would be nice if ipv6 was everywhere
nat is so ick
[20:29]
mnathani_I was ISP Summit Canada today, and folks there believe IPv6 will be ubiquitous within the next 2 years [20:30]
mercutiohmm
i'm pessimistic
[20:30]
mnathani_I think we will see a lot more CGNAT type stuff before IPv6 becomes mainstream [20:31]
brycecI'm realistic :P [20:31]
mercutiois this about having ipv6 support available opt-in
or sites actually serving on ipv6?
[20:31]
mnathani_ISPs rolling it out to subscribers [20:31]
brycecThough I was surprised to see TWC offering native IPv6 at the home office.
(tcpdump picked up their RAs)
[20:31]
mnathani_I'd like to know when it will be OK to provide IPv6 only connections [20:32]
brycecI've been seeing more ISPs offering it than I have websites serving over it.
Google, Facebook, Wikipedia (aka: like 75% of my browsing) are all IPv6 which is great. But Twitter and Netflix are not.
[20:32]
mnathani_Skype isnt either [20:33]
brycecWell Netflix actually seems to vary - right now is IPv6 apparently.
(Last I'd checked it was IPv4)
[20:33]
mnathani_I get BLOCKED
when browsing with IPv6 on
[20:36]
brycecHulu and Amazon are both IPv4-only as well [20:37]
mercutioare any public news sites on ipv6 at all?
maybe some cdn ones
[20:37]
brycecDoes google.com/news count? :P
wikinews.org is ipv6
[20:37]
mercutioebay, amazon, paypal are all ipv4 only
i mean like cnn, fox etc
to use american examples :)
[20:37]
brycecI thought you said news, not drivel? [20:38]
mercutiohaha
even if you don't read them lots of people do
[20:38]
brycecAnd those all return no ipv6 DNS records.
[for me]
[20:39]
mercutioyeah same
i just tried heh, the local news stuff here is ipv4 only too
actually ipv6 adoption is rather weak locally
[20:39]
brycecI blame the hobbits. [20:39]
***Speakz has joined #arpnetworks [20:40]
mercutioi just think no-one cares
the biggest news site is using coldfusion
[20:40]
brycecbrycec knows a CF dev. He hates it. [20:40]
mnathani_my weechat-relay server is running on : 10.10.2.2 port 8001 as well as public IP: port 60001 [20:40]
brycecThat's good to know. I'll start DDOS'ing 10.10.2.2 right away. [20:41]
mnathani_what do I need to change this config to: /ip firewall nat add chain=srcnat src-address=192.168.1.0/24 dst-address=192.168.1.2 protocol=tcp dst-port=80 out-interface=LAN action=masquerade [20:42]
brycecdst-address should be your external IP
dst-port should be 60001
to-address should be 10.10.2.2
(I might be unclear about the port)...
[20:43]
BryceBotThat's what she said!! [20:43]
mercutioany port in a storm [20:44]
brycecheh [20:44]
mnathani_:-) [20:44]
brycec(Full disclaimer,I'm just going off that mikrotik wiki page, and don't actually know this syntax in the slightest) [20:44]
mercutioi prefer to touch routeros as little as possible
so don't have deep understanding
[20:44]
brycec(re-reading the wiki, apparently you should ignore what I've said :P) [20:45]
mercutiomercutio rereads
i don't think i understand the problem
[20:45]
brycecProblem is that from inside his network, he cannot reach $extip:60001 [20:46]
mercutiooh, you can't connect to your public ip from internal [20:46]
brycecFrom outside his network, that works. [20:46]
mercutioyeah that makes much more sense
i'm sure that's googleable
[20:47]
brycecmercutio: read scrollback ;) [20:47]
mercutioi mean not the wiki [20:47]
brycecit was Googled, and here we are now :P [20:47]
mercutiobut real useres.
users
the wiki is terrible
i'd check the forums
[20:47]
brycecAw I thought it looked promising. Only difference between the example and mnathani_'s situation is there's a port forward too, not 1:1 port numbering. [20:47]
mercutiowhy not just relay to arp? [20:48]
brycecwell there were forum results for that too. :P http://stackoverflow.com/questions/20163669/mikrotik-nat-redirect-to-local-from-local seems promising (complete with port number change) [20:48]
mercutiorelaying through your home setup seems messy
or use a dns naem
[20:48]
brycecIf only he had some kind of public server... [20:49]
mercutioand give internal ip for local lookup [20:49]
brycecsplit-horizon DNS? [20:49]
mercutioyeah [20:49]
brycecOf course he'd have to change the internal port number too, but no reason not to [20:49]
mercutiowith dnsmasq it's real easy to overload
so you just force a diff ip for local
[20:49]
brycec(It certainly is) [20:49]
mercutio1 to 1 port mappings are more sensible too [20:50]
brycecNot sure I 100% agree with that [20:50]
mnathani_I can change the port [20:50]
brycecEspecially with things like RDP - you can't change Windows' port it listens on, and all number of bots look for 3389 [20:50]
mnathani_either the public, or the internal one [20:50]
mercutiooh true
yeh that's windows though
i was thinking normal servers :)
[20:50]
mnathani_actually through a registry change you can change the windows rdp port [20:51]
mercutiowith windows it's probably better to vpn in [20:51]
brycecAnd then there are ISP's that block 25/80/443 so you have to port-forward, but you still want the convenience internally [20:51]

mercutioi just run weechat inside tmux myself [20:52]
mnathani_I think I got the ports and IPs correct, but the out interface is confusing me
I dont have one labeled LAN

it's weird how big it is but not tall
weird no ipv6

i don't know much about germany data centres
[22:17]
brycecActually, Google indidcates that Telehouse has IPv6 in several locations
NY, Bulgaria, etc
[22:18]
mercutiowell not their primary site
oh telehouse is UK based isn't it?
[22:19]
brycecWell Telehouse Europe is :p [22:20]
mercutiooh
www.telehouse.net says location of london, Uk
[22:20]
brycecThere's also Telehouse America :P [22:21]
mercutiocloudflare noc is european.
it's pretty hard to tell where things are based these days :)
[22:21]
brycec"Together with its parent company, KDDI and sister company Telehouse Europe, Telehouse America operate a total of 44 Telehouse-branded global data centers in 23 cities throughout Asia, Africa, North America and EMEA." [22:21]
mercutiosince 1990 when it pioneered Europe's first purpose-build data centre in London.. [22:22]
brycecCloudFlare has NOCs all over, as evidenced by a NOC Engineer job listing in SFO. [22:22]
mercutioahh true, the peering one is somewhere near sweden i'm guessing from phone number
actually it's uk
[22:22]
brycecWell they do have a Stockholm location https://www.cloudflare.com/network-map/ [22:23]
mercutiocloudflare is growing quite raidly from what is aw
saw
it's kind of cool because everyone can have CDN
didn't really like the akamai high charging that discouraged small sites.
even their pay for pricing isn't that high
oh yeah nginx just added http/2 to beta version
so http/2 should be around in nginx stable soonish
