RandalSchwartzsome day, I will meet the wise and noble up_the_irons
he should just drop by Maria's Downtown, and that'd make it easy. :)
[17:55]
...... (idle for 27mn)
up_the_ironsRandalSchwartz: where is Maria's? I'm in downtown so little now, having specifically engineered all my gear to be remotely accessible (if something is down, there is no driving to add to additional downtime)
I'd say I can count that as a success :)
RandalSchwartz: are you still in LA?
all: today I will send all the pre-order people their signup link
[18:22]
RandalSchwartzI arrived the 4th, leaving the 16th or so
maria's is 600 block of floswer
flower
[18:26]
up_the_ironsah cool [18:30]
RandalSchwartzoooh, and being mayor on 4square here gives me a free appetizer and dessert!
yeay
[18:31]
up_the_ironsLOL [18:34]
RandalSchwartzbut since I get double miles for my credit card mon-wed, I'll save those for thursday :)
I've got neil's new machine mostly configured... he just has to test and approve before we go live this weekend
and then we can get off that ugly expensive EC2 box
[18:34]
up_the_ironsah cool
how is EC2 pricing these days? I find it kinda confusing so never did real calcs... but from what i've heard isn't it comparable to a vps, like $20 / month for something basic?
[18:40]
***spits has joined #arpnetworks [18:41]
up_the_ironslike if you add up all the "CPU Hours" and crap
for a full month
[18:41]
spitssup [18:41]
***spits has quit IRC (Quit: Page closed) [18:48]
cedwards has quit IRC (Read error: Connection reset by peer) [18:56]
mhoranup_the_irons: I think a basic EC2 instance costs around $70/month.
Ask cmeiklejohn for the details. He's done the calcs.
[18:59]
RandalSchwartzneil's paying about $120/month for about half of what he'll be getting from ARP
so it's about 2 or 3 to 1
and that doesn't count the multiple redundancies
[19:01]
up_the_ironswhat are the multiple redundancies?
mhoran: roger
[19:14]
RandalSchwartzpower supply, disk, network, ultimately the CPU,
EC2 doesn't promise restarting my instance if the physical machine dies
I suspect you would
[19:17]
up_the_ironsRandalSchwartz: doesn't EC2 have redudancy in those things though? I mean, it's supposed to be "cloudy" ;) [19:19]
RandalSchwartzno - they promise restarting the boot image [19:19]
up_the_ironsRandalSchwartz: well yeah, I'd copy all the instances to a new machine [19:19]
RandalSchwartzbut not the live disk [19:19]
up_the_ironsRandalSchwartz: oh i c [19:19]
RandalSchwartzwe've had to calculate that into backup plans [19:19]
up_the_ironsso the live disk is not persistent, in that case? [19:19]
RandalSchwartzright [19:20]
up_the_ironsweird [19:20]
RandalSchwartzI have a script that snapshots to permanent storage [19:20]
up_the_ironsi mean, i assume they still have the live disk stored somewhere [19:20]
RandalSchwartzbut it'd still be a pain to get restarted
Yeah - weird eh?
you can't boot from permanent storage
only attache it
[19:20]
up_the_ironsah ok
I thought you could by now
[19:20]
RandalSchwartznope
so my / is always volatile
I can issue a reboot, and it's preserved
but if they need to migrate, it's dead
[19:21]
up_the_ironsthat seems really dumb; but i think the EC2 market is different than the 24/7/365 uptime machine market [19:21]
RandalSchwartzyup
it's all about servers starting from known AMIs
[19:21]
up_the_ironsgotcha [19:21]
RandalSchwartzso / is really irrelevant [19:22]
up_the_ironsyeah [19:22]
RandalSchwartzwhat's important is where your DB is
and what your IPs are
[19:22]
up_the_ironsgotcha [19:23]
RandalSchwartzin fact, you coudl view local changes to / as distracting
and possibly destructive
you're supposed to get everything as you want for a boot image, then make an AMI from it
and then launch everything from there
it's a different model from a VPS
[19:23]
***heavysixer has quit IRC (Quit: heavysixer) [19:33]
up_the_ironsRandalSchwartz: ah ok, so you can make your own AMI's, but not have an "forever evolving" AMI which would be like a VPS, always at the last state you had it [19:40]
RandalSchwartzright
you *can* reboot your own server
but they don't promise eternal existance of it
so it's possible you'll have to boot from an AMI
as I said, you offer the far better deal for most mortals
and I really appreciate getting off the single dedicated box in texas
because god-forbit that thing go down... it'd be my problem to have backed up to another disk somewhere off box
where I know you have my disk in a place that a new CPU can look at it
and since I'm not the only guy on the box, many people would be yelling at you :)
so I don't have to be the guy yelling
[19:40]
up_the_ironsRandalSchwartz: haha, yeah that's true
a buddy of mine had his dedicated box die recently; he then just bought a vps with me
[19:44]
RandalSchwartzthere's an advantage in numbers [19:45]
up_the_ironsyeah [19:45]
RandalSchwartzI know there's a slight security risk in the ring0 being penetrated, but that's all worth the upside [19:46]
up_the_ironsyeah
i fear that enough to take measures to avoid it
[19:46]
RandalSchwartzhave you seen any recent hacks that break ring0 [19:47]
up_the_ironstheoretical ones have been demonstrated [19:47]
RandalSchwartzyeah, just wondering about things in the field
you said you'd be rebooting when you needed to update. I don't recall any of those.
[19:47]
up_the_ironsthe debian / ubuntu security mailing list shows them from time to time, but when I see "[so and so] has demonstrated [such and such]", i never know if that "hack" was disclosed or still secret
I tend not to want to reboot every time a security update comes out. Many are not applicable. The ones that are can build up into a "super" update. Unfortunately, if I rebooted every time a Linux kernel hack came out, it'd be every few weeks
[19:48]
RandalSchwartzyeah - that's what I expected.
I guess you don't do that
[19:50]
up_the_ironsthe break-ins we've seen in the past (like the fsckvps fiasco) tend to come from weaker links, like bad / common passwords, leaving this too open, etc... [19:51]
RandalSchwartzok
yeah, it'll always be low-hanging fruit
[19:51]
up_the_ironss/this/things/ [19:52]
RandalSchwartzhence, no more sshd on 22 for me [19:52]
up_the_ironsyeah me either [19:52]
RandalSchwartzneil's first box was getting hammered 24x7
so I just removed that
dictionary attacks, coordinated from 30 IPs
so clearly it was a mass attack
[19:52]
up_the_ironsyeah [19:53]
RandalSchwartza .. z but from rotating 30 IPs
bad guys got too much resourcs
I blame redmond
[19:53]
up_the_ironssame [19:53]
RandalSchwartzfor all the good that having windows made business buy computers...
I wonder if enough bad has already been done to reset that
[19:54]
up_the_ironsgotta wonder [19:54]
RandalSchwartzconsidering that 80%+ of spam is from zombies...
and zombies couldn't exist without windows desktop idiots visiting pr0n sites
[19:55]
up_the_ironsgotta return some movies to the video store...
up_the_irons wonders off
