WhoWhatWhen
plettI had a quick play with bhyve in 10.0 and never got anywhere with it. Maybe I should revisit it
I see that libvirt supports it now, that will make my life easier

mnathani_staticsafe: have you tried contacting their noc? I know you are not a cogent customer or anything so not sure how helpful they would be [14:31]
staticsafethey would politely tell me to fuck off :P [14:31]
mnathani_but all their customers cant reach you either
:)
[14:32]
mercutioi don't think it's cogent's fault anyway
cos ntt isn't working either
[14:39]
mnathani_ntt is directly connected to arp though isnt it? [14:41]
mercutioyes [14:41]
mnathani_Seen by #peers: 15
that number is rising
[14:42]
mercutiowhat is it now? [14:42]
mnathani_15 [14:42]
mercutiothat's what it was yesterday [14:42]
mnathani_was 5 yesterday
when I tried
[14:42]
mercutioit's ~230 for other ip's
it was 15 when i tried
[14:42]
mnathani_would the 32 bit ASN make a difference? [14:52]
mercutiomaybe [14:53]
mnathani_Seen by #peers: 15
9 orochi-sov-interconnect.mythic-beasts.com (93.93.133.42) 94 msec 99 msec 93 msec
10 192.67.222.1 89 msec 88 msec 89 msec
does that hop 10 mean someone else is advertising the net block?
[14:53]
mercutiothat's his ip
hop 9 is his interconnect /30 or whatever
[14:55]
mnathani_2 AS PATH as per NTT LG
3356 3491 40193 25795 393949
12496 12496 12496 44684 393949
staticsafe did mention he was trying Anycast?
[14:56]
mercutiothe thing is it should be advertised to ntt
not via trit
maybe as well
so asn path should be shorter
[14:57]
mnathani_is it like a convergence time for BGP? [14:57]
mercutionope
it's like routing policy mess
because bgp doesn't do such
well it could be - or it could be something simple like the route filters for export on arp didn't catch it properly because of beign 32bit asn instead of 16bit and doint translation
[14:58]
staticsafeim going to send an email to Mythic Beasts asking if their filter configuration is complete [15:02]
............ (idle for 59mn)
mercutiooh one of the other hosts changed now
ntt !
oh hangon it's more complicated than that
it changed then it chagned back!
http://pastebin.com/dEN2E6S3
ahh it looks like they shifted from ntt to gtt temp at one point
[16:01]

up_the_ironsanyone who has their /48 IPv6 routed to them have any references to HOWTOs on how you set it up? I'm asking only because there's a customer that has requested this, and despite me insisting it is an "experts only" feature, he can't figure it out but still doesn't want to give up. i want to point him to some resources. [18:08]
RandalSchwartzthat seems doable, but I haven't done it. :) [18:15]
mnathani_up_the_irons: what OS? [18:26]
up_the_ironsmnathani_: CentOS [18:28]
mnathani_is this an IRC person? If so I can assist via IRC
I am running CentOS with a routed /48
if not an IRC person - I can provide my config

mnathani_brycec helped me out when configuring my IPv6, though his instructions were debian / ubuntu styled [18:39]
up_the_ironsmnathani_: awesome, thanks for that! [18:46]
mnathani_up_the_irons: You are welcome! Happy to help out. [18:56]

mercutioi beat you by 3 weeks :) [20:43]
mnathani_I kinda remember being drawn to ARP due to the FreeBSD and IPv6 support - both of which I had never worked with before [20:53]
mercutioyeh ipv6 wasn't so common back then [21:00]

up from 15
[21:10]
I just compiled mtr from the git repo
and now all it says is Start with date
no trace output
[21:17]
mercutioweird
what's new in mtr in git?
arch has a git aur pkg i think
[21:17]
mnathani_last release was 0.86
not sure whats new in git
thought I would get the latest version
[21:18]
mercutio0.86 isn't recent enough? [21:18]
mnathani_my version was .75 [21:19]
mercutioahh
arch has 0.86 ;)
[21:19]
mnathani_trying to get newer version
I am running CentOS
[21:19]
mercutioubuntu has 0.85
ahh yeah
centos tends to be old
centos6?
[21:19]
mnathani_6
yea
I must be missing something
its like I get a prompt to enter something
mtr 4.2.2.2
Start: Sat May 9 00:17:07 2015
[21:19]
mercutiodid you enable curses? [21:20]
mnathani_dont think so [21:20]
mercutioi dunno if it does by default or not
but i disable gtk
and if it's not showing anything..
[21:21]
mnathani_mtr --report google.com does work though [21:21]
mercutioipinfo lookup hmm [21:22]
mnathani_checking ncurses.h usability... no

[21:22]
mercutiook that's your issue, install the curses dev package
hey i got the same thing on ubuntu
/except/ it shows lines 1 at a time
after big delay
yeh installing curses-dev fixed it on ubuntu
[21:23]
mnathani_there we go
it should complain more if no curses
[21:24]
mercutioheh
what's this ipinfo thing
oh try -y
err -y IPINFO
it tells you the ASN's
it's in 0.85 too
[21:24]
mnathani_y you mean during the output?
it gives me the block
[21:26]
mercutiomtr -y IPINFO 4.2.2.1 etc [21:27]
mnathani_I think hitting y does the same time [21:27]
mercutiooh [21:27]
mnathani_repeatedly
switches the view
[21:27]
mercutiohitting y does ntohing for me normally [21:27]
mnathani_My traceroute [v0.86+git:592de82d] [21:27]
mercutiomtr 0.86+git:592de82d
yeh same version
[21:28]
mnathani_toggles between prefix, AS NUmber, Country, ARIN etc [21:28]
mercutioyeh ? seems to suggest there is such an option
it just doesn't work for me
but mtr -y IPNFO does
[21:28]
mnathani_are you in screen or something? [21:28]
mercutiooh [21:28]
mnathani_I am in tmux and it works for me [21:28]
mercutioif i use -y IPINFO then it works [21:29]
mnathani_cool [21:29]
mercutioi mean y works if already doing -y IPINFO
juust not without
[21:29]
mnathani_mtr -4z [21:29]
mercutioweird i found some field which was usually a date code [21:29]
mnathani_I was in that option [21:29]
mercutiobut it's showing 3356 for level3 :/ [21:29]
mnathani_mtr -4z 4.2.2.2 [21:29]
mercutiowhh -z does work too
it's not in my man paeg though?
yhow did you figure that out?
[21:29]
mnathani_I think you told me about that option a long time ago [21:30]
mercutioheh
and then forgot about it? :)
i usually use traceroute -A
if i want to see asn's
[21:31]
mnathani_2014-07-09 20:19:03 m0unds mtr -z4 somev4host.domain.tld
it was actually m0unds
[21:32]
mercutiocool
'cos i didn't remember that at all :)
hmm i'm playing with mtr -T now :)
[21:32]
mnathani_what does that option do? [21:37]
mercutiodoes a tcp traceroute
mtr seems to show high tcp pings for last hops
but tcptraceroute doesn't.
[21:37]
mnathani_perhaps it uses a different port
that gets prioritized differently
[21:47]
mercutioyeh it could be
i haven't looked into it yet
that path changing stuff is real btw
[21:48]
mnathani_you referring to the ntt stuff? [21:49]
mercutiotheres' heaps of load balancing that shows up easily with tcp but not icmp
when you trace nearly anywhere with mtr
level3 etc are bad too
[21:50]
mnathani_how is load balancing bad? [21:50]
mercutioit's not necessarily.
it just means you can have inconsistent performance
like i can ssh to the same host and have different latencies different times
that can be different by like 30 msec
which is noticable.
but bandwidth can vary too
[21:50]
mnathani_right [21:51]

how come the tmux that arch installs is so different than the one I get with centos or ubuntu? [22:27]
.... (idle for 17mn)
jbergstroemmercutio: it depends on how often you're willing to update. between updates its very stable imo - but there's been some minor hiccups that "forces" me to update -- change to bootloader, the arc4random thing and so on. you need to track upstream (if you care) every now and then [22:44]
mercutioso it's similar to tracking openbsd i suppose
i've found openbsd -current pretty stable except hiccups
the time thing was kind of annoying
