m0undshaha
haven't noticed any issues for a while
comcast just deployed some new gear in my area, so i've been seeing +/- .7ms or so to arp for the last few days
[09:36]
brycecbrycec is having major TWC issues this a.m. :(
(but it might also be my own gear at fault)
(either way, I'm seeing 300+ms to the cable modem 2 feet away)
[09:41]

up_the_ironsmnathani: for larger amounts of ram, you need registered. udimm's can still certainly be used in servers. all our dedi's have udimm's, but the are of course ECC too. we don't need rdimm's on the dedi's b/c ram count is not too high [15:28]
mnathaniup_the_irons: thanks [15:31]
up_the_ironsnp [15:31]
***Konata has quit IRC (Quit: Leaving...) [15:32]
mnathaniup_the_irons: How do you manage IP address assignments across ARP Networks customers? Spreadsheet, or something more elegant?
Perhaps something like phpIPAM
[15:32]
up_the_ironsmnathani: internal app i wrote. uses rfc 3531 allocation method (can be used on ipv4 also). parts of it are somewhere on my github.
the "spreadsheet method" lost scale long ago ;)
[15:34]
mnathaniyour app take care of historic VLAN assignments as well? [15:35]
up_the_ironshistoric?
it takes care of vlan assignments; not sure what you mean by historic
[15:35]
mnathaniover time, like presently vlan 10 is assigned to a range, but before that it used to be vlan 20 etc [15:36]
CaZeWhat if you get a subpoena for an IP that ended service like six months ago? [15:36]
mnathanias customer turn over takes place [15:37]
up_the_ironsit does not keep history like that, no. i have rancid on all my switches, so if i really wanted to see the past, i could pull it up via CVS (ick, i know)
CaZe: you would respond to the court and say the IP is no longer in use
[15:37]
mercutioregistered ram is actually cheaper at least on ebay
and you can get bigger sticks
up to 16gb on ddr3 i think, which is how people get 192gb of ram etc
(6 per cpu)
[15:41]
up_the_ironsyeah udimm's can be more expensive [15:49]
.... (idle for 18mn)
mercutiowell ecc udimms can be at least
looks like 8gb cost a bit more still
[16:07]
up_the_ironsyeah i meant ecc [16:17]
hazardoushi nerds!!!

RandalSchwartzgeek. not nerd
no pocket protector here
[16:53]
mercutiosure sure :") [17:03]
RandalSchwartzoh - I admit... I used to have an HP41C attached to my belt. but never a pocket protector.
RandalSchwartz wonders how many people in channel will be googling HP41C to see what it was.
[17:12]
novaenovae googled it [17:17]
CaZeCaZe wonders how many people in the channel didn't have to google it to know what it was [17:18]
.... (idle for 17mn)
up_the_ironslol [17:35]
mercutioit's a calculator isn't it?
with reverse polish notation?
oh shit now i must be a nerd
[17:41]
RandalSchwartza hospital, what is it! [17:47]
mercutioup_the_irons: did hivelocity ever update saying anything more than they'd look into it? [17:56]
up_the_ironsno [17:56]
mercutioit's still down it seems. [17:56]
up_the_ironsbang on their door [17:57]
mercutioheh
i'm not a customer of theirs
but you never know
[17:57]
up_the_ironsstill, noc's get emails from the outside all the time
anyway, i've just disabled their session
(just now)
no point leaving up something broken that they don't seem to care to fix
[17:57]
mercutioahh ok
it still looks the same sdo far
10.10.10.6 is last hop
did people start using the new ip adddress block much yet?
for coresite
[17:58]
up_the_ironseveryone has migrated [17:59]
mercutioahh ok
is 10.10.10.6 your peering box?
[17:59]
up_the_ironsoh crap, they send routes over any2easy too [18:00]
mercutioahh [18:00]
up_the_ironsnot as easy to filter
i could do it, just not now
[18:00]
mercutiois this a reverse path filter issue?
with assymetric routing
[18:00]
RandalSchwartzthis weekend.... is upgrade weekend!
just gonna use csup to get from 8.3 to 8.4
minimal ruisk
[18:05]
mercutiofreebsd? [18:05]
RandalSchwartzbut I also have to go from perl 5.10 to 5.16 :)
yeah
also upgrading to pkgng
[18:05]
mercutiocautious :) [18:06]
RandalSchwartzand probably installing poudeiere to do my package building from now on [18:06]
brycecbrycec didn't have to google it... I had an HP-48 [18:06]
mercutioi haven't seen perl being that annoying recently with upgrades
not compared to in the past
php is still nasty though :)
[18:06]
RandalSchwartzyeah - I have a half dozen bsdpan though
hopefully none of them have XS
[18:07]
mercutioit's a bit disconcerting how much stuff doesn't support python3 [18:07]
RandalSchwartzhmm. WTF. IO::Tty is bsdpan? [18:08]
brycecReal schism in the Python world, with python3 [18:08]
RandalSchwartzshould be able to replace that with a real port [18:08]
mercutioat least python 2.7 still seems to be supported and you can have both at once
arch linux changed /usr/bin/python or whatever to point to python3
it's a way to break a lot of things.
[18:08]
RandalSchwartzawesome - http://www.freshports.org/devel/p5-IO-Tty/
so zero bsdpan now
[18:09]
mercutiocool. [18:09]
RandalSchwartzprobably have to force-install since it'll have to overwrite the bsdpan stuff [18:09]
mercutioup_the_irons: is level3 capacity up yet btw? [18:11]
up_the_ironsok, i created a "bad peer" filter and now hivelocity routes should be eradicated [18:12]
mercutiowell route changed and it's not working
i wonder if it's the reverse path
[18:13]
up_the_ironsmercutio: not yet; everything is done i just need to find time to set up the vlans and turn up the sessions. There was a big delay when I requested that they renumber the vlans they gave me (cuz I had them already in use) [18:13]
mercutioit's going via AS11799 now [18:13]
up_the_ironsoh god
so yeah, bgp collective picked it up
[18:13]
mercutiowell that's from whois [18:13]
up_the_ironsand they probably have the exact same problem [18:14]
mercutioerr reverse lookup even
hahaha
shit
you'd think hivelocity would fix it then
cos surely it's affecting lots of people
[18:14]
up_the_ironsyeah [18:14]
mercutioi do wonder about the vlan thing
4096 vlans isn't many
it's easy to get clashes
[18:14]
up_the_ironshappens all the time [18:15]
mercutioand vlan over vlan is a stupid way to go about things :)
hmm, here vlans are done because there's often national/international split etc
but is there any reason it actually needs to be tagged for you?
[18:15]
brycecGood point... I don't see why it couldn't be handed off un-tagged, [18:17]
mercutioi can see lots of reasons in general bryce :)
i normally advocate tagging...
like there may be a different vlan to send ddos blocks
[18:17]
brycectagging is swell, but I figure when it comes to the handoff of a single connection, I reckon they could hand it off un-tagged and let you absorb it as you wish, tag it on your switch, etc [18:18]
mercutioalso you can do the thing of having two vlans that talk to different routers
that share the same bandwidth allotment
so you plug into switch that then plugs into two routers
which means you have switch as point of failure rather than router
but then you have two switches and two cables, if you want to fix that
but then it's normally failover only, and each router can talk normally, so you can use both routers for transit
and only in the case of switch failure switch cables
and pay for bandwidth allotment rather than two
[18:20]
up_the_ironsmercutio: brycec : it's handed off tagged b/c i request 2 separate sessions (for redundancy) [18:24]
mercutioahh cool, well that's a good enough reason to me :) [18:24]
brycecbrycec nods [18:24]
mercutiobgp is so slow when sessions go down [18:25]
staticsafeyes [18:26]
mercutiowith all the talk of ddos and 10 gigabit+ links etc
bgp still takes ages to converge
[18:26]
easymacsome carriers run bfd with their customers [18:35]
mercutio*cough*
that can make it worse
[18:35]
easymachow so? [18:36]
mercutiobfd can lose sync
when the connection is up
esp. with ddos attacks
and means the total outage time is worse
[18:36]
easymaci suppose [18:36]
mercutioddos attacks are pretty common these days [18:37]
easymacthen what's the solution? [18:37]
mercutiomore common than fibre failures i imagine [18:37]
RandalSchwartzupgrade from ddos to dwindows :) [18:37]
easymacRandalSchwartz++ [18:37]
mercutiousually it's fibre level redundancy
with link path fast failover
and redundant sessions
and redundant routing engines
but that starts getting more expensiveetc
[18:37]
staticsaferedundant all the things [18:42]
m0undsRandalSchwartz: baahaaahaaaaa [18:44]
brycecRedundancy! Load-balancing with failover!
CARP!
[18:45]
m0undsaw carp [18:45]
RandalSchwartzcarp diem
fish of the day
[18:46]
staticsafethe CARP drama on NANOG recently was great [18:46]
m0undsi saw a lady with "carpe deim" tattooed on her back
not to be confused with carpe diem
carp drama?
[18:46]
bryceclol m0unds [18:47]

[18:50]
brycec(Yay Henning Brauer)
He's a good dev
[18:51]
mercutioyeah he does seem good [18:52]
RandalSchwartzcarp dime
10 cents a day
[18:52]
seize the dime! [18:57]
brycecbrycec steals RandalSchwartz's dime
Wow this nong thread is godawful
[18:58]
staticsafeit got pretty bad yeah [18:59]
brycec"So yes, the problem only exists if you are running VRRP and CARP on the same subnet and happen to have a host identifier conflict."
brycec wonders why he's wasting so much brainpower on this
[19:00]
mercutiomasochistic [19:01]
brycechaha [19:01]
RandalSchwartzthe problem happens only if the moon is in the seventh house... [19:04]
mercutioryan shea is a troll
oh so is paul wall
i wonder if they're from cisco or something
[19:05]
brycec(Feels like Paul Wall is the bigger troll, so far) [19:08]
m0undsgoogle
haha
[19:08]
mercutiogmail you mean?
i don't turst people with gmail addressses :/
[19:09]
RandalSchwartzbetter than hotmail! [19:09]
m0undsno [19:09]
mercutionot really
same diff
same with yahoo etc
[19:09]
m0undsryan shea @ google.com [19:09]
brycecRyan Shea has a google.com address [19:09]
RandalSchwartzor comcast.net [19:09]
m0undsis that dude's addr
durr
[19:09]
mercutiohave a work or personal domain [19:09]
brycecexcept @google.com is legit, corporate google [19:09]
m0undsyes [19:10]
RandalSchwartzI see bizcards that list @comcast.net
and I go... WTF
[19:10]
brycecI'm with you RandalSchwartz [19:10]
m0undsi've seen verizon.net on biz cards before [19:10]
RandalSchwartzgeez [19:10]
mercutioexactly [19:10]
m0undsor verizon.com, whichever their hsi email domain is [19:10]
brycecI see sooo many doctors offices with @aol.com [19:10]
mercutioit doesnt' inspsire confidence
unless it's a small individual
or small company
[19:10]
m0undssmall in stature?
like a mouse?
[19:10]
mercutiothat isn't internet related
but as soon as you're doing internet related stuff it's expected
[19:10]
brycecI love when doctors offices have a website, but email @isp/webmail.com [19:11]
m0undshahaha, yeah [19:11]
mercutiohaha [19:11]
RandalSchwartzheh [19:11]
m0undsmy dentist's office recently changed from an @qwestbusiness email (or somesuch)
q.biz or something
[19:11]
RandalSchwartzseriously - you can't afford $7/year for a forwarding domain? :) [19:11]
m0undshaha
it's really funny too when an office uses comcast biz, but they never got help configuring the hosted exchange that gets bundled w/that connection
so you see @comcast.net when they could do @domain.tld via a svc they're effectively paying for
[19:11]
brycec(TIL that comcastbiz comes with exchange) [19:12]
m0undsyeah, it's 2007 or 2010
5 or 10 users too
[19:13]
brycecIt's sad, we have TW-biz, and all I know is IP block we're allocated. No idea what else it comes with
(because the guy who handles the account is useless)
[19:14]
m0undsah, rep w/TW? [19:14]
brycecNo, I meant the company owner who called TW and said "we need Internet" never passed any of the information along [19:15]
m0undsjust logged in to my acct to look - came with 5 accts, also some amount of sharepoint space too
oh, gotcha
[19:15]
mercutioi dunno why i reading the web archives of nanog
i'm subscribed
[19:15]
m0undshahaha [19:15]
brycecHe told me that a TW guy was coming out, and the TW guy setup the cable drop and modem and handed me a piece of paper with the IP
lol mercutio
[19:15]
mercutioi don't read it often
it's got it's own folder
[19:16]
m0undsyeah, that's part of why i unsubbed
wasn't reading it because i kept seeing the same inane stuff popping up day after day
[19:16]
mercutioi thought it was interesting that people were talking about new zealand
but not the subject matter argh
[19:16]
m0undsand i couldn't be bothered to dig into it to see interesting stuff [19:16]
mercutioevery isp has to be registered here now [19:17]
m0undsthen there was some event early this year or late last year that resulted in /tons/ of digest msgs, so i unsubbed [19:17]
mercutiowhere isp is a loose term
which basically means anyone that provides network capabilities iirc
[19:17]
brycecmercutio: Would a home wifi connection qualify as "ISP"? :p [19:18]
m0undshahahaha [19:19]
mercutioif you sold it to your neighbours probably [19:20]
brycecBut if it's given away freely?
Like a coffee-shop?
[19:20]
mercutiono idea
coffee shops charge for internet here
[19:21]
brycecAh [19:21]
mercutiomcdonalds has free internet i hear
but i haven't been there
usually 3g is faster than cafe internet anyway :/
[19:21]
m0undsuser@goldenarches.net [19:21]
mercutiomost are just adsl connections
with shit routerse
[19:21]
brycecOuch. I don't know about 3G, but LTE is certainly faster than every hotspot I've tried lately [19:22]
m0undsi don't know the last time i used public wifi somewhere [19:22]
mercutiowhere you have to put in some coupon code
which is annoying if you use a tablet
[19:22]
m0undsat&t provides their own preconfigured gateway for most attwifi hotspots in restaurants and offices and stuff
don't remember what it is, but it handles the captiveportal and network registration stuff
[19:22]
brycecbrycec isn't surprised [19:22]
m0undsprobably a lot easier for at&t and for businesses that offer free wifi branded by at&t [19:23]
haha, can't wait for verizon to start marketing "XLTE" more
FOUR GEE EX EL TEE EE
