WhoWhatWhen
mercutioit shoudl aslo probably be extended to 703 and verizon
err s/verizon/comcast/

***KILLALLHUMANS01 has quit IRC (Ping timeout: 240 seconds) [00:05]
acf_up_the_irons: here's a paste
ip as-path access-list 4 permit _701_
ip as-path access-list 4 deny .*
route-map crappyisp permit 10
match as-path 4
set as-path prepend 25795
I mean http://paste.unixcube.org/k/961352
[00:10]
mercutiooh did i delete the line somehow [00:11]
acf_don't think so
I just added it
[00:11]
mercutiook cool [00:11]
***KILLALLHUMANS01 has joined #arpnetworks

[00:11]
up_the_ironsacf_: ok interesting [00:13]
acf_http://paste.unixcube.org/k/6e9d7a
^ contains more ASNs (in case you wanted to match more)
[00:14]
mercutioverizon is still congesting
i left a trace running
i thoguht it was ok by this time normally
acf: there's also at&t
maybe just prepend all ntt traffic by one :)
[00:23]
acf_oh forgot about them [00:24]
mercutioat&t have two asn's [00:25]
acf_are there any others I missed?
like Time Warner or Frontier or something
[00:25]
mercutioAS7018, AS17233
tbh, i think it's better to go step by step
it's unknown whether it's forward or reverse path
and level3 isn't advertised yet i think
[00:25]
acf_yeah
for Verizon I think we determined forward from arp
[00:26]
mercutioand for every one you add it's good to make note of before/after
so you can complain to ntt properly :)
[00:27]
up_the_irons-rw-r--r-- 1 garry garry 13227 Jun 14 2000 objects.php
hmmm
that's one OLD server
[00:27]
mercutioit's an old server not an old file?
is that php3 or php4? :)
[00:27]
acf_looks like verizon is *not congested* for about 6 hours/day [00:28]
mercutiooh wow
that's pretty insane
[00:29]
acf_that is it's congested 75% of the time
http://kremvax.acfsys.net/smokeping.cgi?epoch_start=1402988400;hierarchy=;epoch_end=1403024400;target=Remote.verizonnet;displaymode=n;start=2014-06-17%2000%3A00;end=2014-06-17%2010%3A00
those are the six
[00:29]
mercutioacf: well some of that level3 blog stuff was disturbing
100 gigabit links run to capacity
[00:29]
acf_I didn't notice the capacity of the links
oh wow "It is a 100Gbps interconnect in Dallas"
[00:30]
mercutiono excuses for that really
you can't say it's only a few users
[00:33]
acf_I wonder if Verizon, etc... will even be better with Level3
given that they have the same issues
[00:35]
mercutioi think so
it's worth a shot
[00:35]
acf_http://blog.level3.com/wp-content/uploads/2014/05/route_info_1.jpg
the text blotched out is potentially "verizon"
or "comcast"
[00:35]
mercutioup_the_irons could add a static route for /32 of verizon.net
that's dallas
[00:36]
acf_that's a really good idea actually
because it wouldn't really affect anything
[00:36]
mercutiothat's how i normally test things [00:37]
.... (idle for 19mn)
up_the_ironsmercutio: pretty sure that is php3 :) [00:56]
mercutioyeah it's about the transition time
and if you aren't quick to leap on new stuff now, you probably wern't back then :)
[00:56]
up_the_irons:) [00:56]
mercutiowhat do you think about our idea of a shared lan segment different from the backup one? [00:57]
up_the_ironsit's possible
hardly a lot of demand though
and really wouldn't be any different than the backup one

brycecI would've guessed PHP4. PHP3 was still traditionally .php3 , the .php didn't come about until php4
Of course you could always use whatever extension you wanted... But as far as what the docs showed/said to use.

mercutiobrycec: point, i wonder :) [15:43]
bryceclol phtml [15:43]
mercutioi don't remember phtml [15:44]
brycecheh http://stackoverflow.com/questions/11859015/what-is-phtml-and-when-should-i-use-a-phtml-extension-rather-than-php [15:44]
mercutiogoogle knows all
oh php2, i don't remember php2
php stated at php3 for me
[15:45]
brycecSame. I knew of PHP2, but it wasn't really "a thing" yet. PHP3 was when it broke free and got popular
Also PHP2 sucked
[15:46]
mercutiophp still sucks :)
although at least people are investing in making things faster
fwiw, apparently lua jit is extremely fast
[15:46]
brycecPHP sucks for vastly different reasons than PHP2 did
php2 was still hacked together, php3 they had a working parser and stuff
And overall, the language is still poorly thought out with inconsistencies everywhere.
[15:48]
***Guest3064 has quit IRC (Ping timeout: 272 seconds) [15:49]
mercutiolike perl [15:49]
brycec(Some functions are $needle,$haystack, others are $haystack,$needle. and both need to die in a fire)
@diaf php
[15:49]
BryceBotphp, AAAAAAGGGGGHHHHHH IT BURNS IT BURNS IT BURNS. Oh. Wait. No it doesn't. I have no feelings. [15:49]
mercutioi don't erally like the notion of each page being independant code
and just pulling in what it needs
i prefer the idea of applications, that deal with various areas
and run all the time
but php is fine as far as footer/header/small amounts of code
i suppose that's a separate issue
the problem with php is that it's "good enough"

mnathaniAnyone else get spam from: ARIN Ticketing System today? [20:37]
erratic_heh [20:37]
.......... (idle for 46mn)
mnathaniwhats a good way to copy / paste mtr output so it is still legible? [21:23]
mercutioresize the wnidow to not be too wide
and paste it into something with a monospaced font
it'd be kind of cool if it could automatically just store results
and be able to create reports etc :)
if you run it with --report it's easier
but you don't get result until the end
[21:24]
mnathanithanks, trying --report now [21:26]
mercutioyou do --report-cycles=25 etc for how many you want
it defaults to 1 a second, so that'll take 25 seconds
[21:27]
mnathaniyea set to 100
the congestion or whatever that was I was trying to troubleshoot has cleared up though
[21:27]
mercutiothat's why repotr is annoying
because you do a mtr, and you identify an issue
then you want to reproduce with report and it's behaving itself.
[21:28]
mnathanihttp://pastebin.com/F73iFTPQ
thats my mtr report showing both directions
80msec is kinda high though for LAX to SJE
[21:29]
mercutiodamn nlayer and their icmp deprioristation
it's going cia chicago i think?
ae4-587.cr2.ord1.us.nlayer.net
that's chicago right?
[21:31]
mnathanilooks like it
@iata ord
[21:31]
BryceBotORD: O'Hare International Airport (formerly Orchard Depot Field) located in Chicago, Illinois, United States [21:31]
mercutioso nlayer san jose to los angeles is via chicago
so nlayer have a down link in california i imagine
because i imagnie normally it's direct
[21:32]
mnathaniwhat about above.net
lax to sje with 80msec
[21:32]
mercutioho hmm
ahh.. but what's the return path for above.net ?
from san jose
[21:32]
mnathaninlayer again?
traceroutes really confuse me
[21:33]
mercutiooh, it looks iltk it yes
so yeah it's just the nlayer issue
most liskely
it's what 10 msec from san jose to los angeles noramlly
and 55 msec from san jose to chicago?
that's both directions
so really it's behaving like it's going via chicago in both directions latency wise
so it may be that there's congestion due to link failure as well
it's 52 msec to chicago from asn jose
san
via cogent
and 60 msec from los angeles
[21:33]
mnathanilol
its back to sub 15msec
end to end
[21:35]
mercutiothat's still high
i'm getting 8.9 msec from san jose to los angeles
but i suppose that's normal if it's dsl/cable/etc
[21:35]
mnathanimore like 10msec actually [21:36]
mercutiooh yip
that's what you'd expect
so yeah i'd go with some congestion plus rerouting
where congestion was prboably created from the rerouting
[21:36]
mnathaniatleast they didnt just drop the packets
http://pastebin.com/vWyaM7s2 < Thats the updated mtr reports
[21:39]
mercutioyeah
this paste has been removed oh
i was having cut and paste issues a,d it added %20 <
yeah that looks good
it's only icmp deprioritisation making it look high
[21:40]
mnathaniIf the issue persisted, would ARP or the other host look into it? [21:43]
mercutionlayer would be the one to look into it [21:45]
mnathanithey probably would not even talk to me - seeing how I am not a customer of theirs
maybe emailing their noc might help
[21:45]
mercutioprobably not
nlayer is reasnoably ok
[21:47]
mnathanitinet, gtt, and nlayer are all the same? [21:58]
mercutiotinet isn't
gtt bought out mzima who bought out nlayer i think?
[21:58]
mnathaniIn April 2013 GTT acquired the IP network Tinet from Inteliquent, for $54.5 million in cash and services.[6]
as per wikipedia
[21:59]
mercutiooh [21:59]
............... (idle for 1h14mn)
hazardousi still stand by my b elief that inteliquent is almost as bad/weird a name as ti sparkle [23:13]
