@Cole Why are you thinking about shit anyway

Dennis Kaarsemaker

@Cole try focusing on boobs instead.

JohnMerlino

Can I question about at commands on this site? I just want to know if there is a universal at command that dumps the modem info, such as the ip address its using, etc

Dennis Kaarsemaker

Hayes command set

In computer telecommunication, the Hayes command set is a specific command language originally developed for the Hayes Smartmodem 300 baud modem in 1981. The command set consists of a series of short text strings which combine together to produce complete commands for operations such as dialing, hanging up, and changing the parameters of the connection. The vast majority of dialup modems use the Hayes command set in numerous variations. The command set covered only those operations supported by the earliest 300 bit/s modems. When new commands were required to control additional functiona...

AT&V Status
ATI Status (Manufacturer, Model, Revision, IMEI, capabilities)

and modems don't know about IP addresses, that's PPP's job.

JohnMerlino

thanks

ManuelSchneid3r

Hi. Can anyone give me some homeserver hardware recs?

Just a few hints. I dont know where to start. I thought starting with the cpu would be fine. What do you think of i3-3227U?

jscott

14:13

Get a Mac mini and a Time capsule.

Cole

Fuck NFS

ManuelSchneid3r

Mac Mini? Time capsule?

jscott

@ManuelSchneid3r Works great for me.

voretaq7

@DennisKaarsemaker ATH0

Cole

Well NFS on Windows to a Solaris box is making me want to punch myself in the face.

voretaq7

14:15

@Cole Use protection.

ManuelSchneid3r

Okay let me specify what I need first

Dennis Kaarsemaker

@voretaq7 +++ATH0

jscott

@ManuelSchneid3r Ah, requirements, yeah, that'll help. :)

voretaq7

@ManuelSchneid3r IBM Power 7

Everyone needs Power7 hardware :-P

for everything.

jscott

@voretaq7 But Power8 coming Real Soon!

Dennis Kaarsemaker

14:16

yuck, home servers

I'll tune out for this one

voretaq7

@jscott yes and when it's released everyone will need that.

ManuelSchneid3r

1. priority is powerconsumption. I will first run RAID1 2x2TB later eventually RAID5 3x2TB. I guess this will make up to 15Watts of power. But I do need those rarely. I guess every second day. All other time those shall be in standby. Well due to this, the idle consumption will mostly result form the rest of the system.

I will need this for streaming to HTPCs at home, webserver, mailserver, git repos, fileserver an some linux experiments.

Jacob

Hey all

ManuelSchneid3r

So I need a perfect combination of CPU, Mainboard, RAM ca 16GB SSD.

Tanner

@Jacob How goes it?

Jacob

14:21

Everytime the word cPa*** appears that message should be flagged as inappropriate

2

ManuelSchneid3r

I will try to undervolt the system. And my goal is to reach at most 20W in idle not runnning the HDDs. Do you have any suggestions?

Jacob

@Tanner Waiting for my roommate to show up on move in day.

Tanner

Root Access

For all you Super Users out there. You have backups, right?

5

Dennis Kaarsemaker

@ManuelSchneid3r yes. Read the message in the top right of the screen

Tanner

Try there.

Dennis Kaarsemaker

14:22

then go to superuser.com

jscott

@ManuelSchneid3r If you just want low power, there's lots of mini-ITX stuff out there. What sort connectivity for your drives?

Jacob

@ManuelSchneid3r Why bother? Power isn't too bad?

ManuelSchneid3r

SATA. Or what do mean?

Tom O'Connor

@ManuelSchneid3r Please don't do RAID 5 with big disks. You will lose all your hard-earned data. Use RAID6 instead.

Jacob

@TomO'Connor This is very true... If you want to go all RAID Cowboy than you might aswell use RAID0 because your data will get lost either way...

jscott

14:26

@ManuelSchneid3r Here's a CD101-N2800, 1.86GHz Atom, 6.5 W <=4GB RAM -- note that's just an quick Google example. There are lots of other manufacturers and models out there.

Dennis Kaarsemaker

@TomO'Connor raid 1+0. 5 and 6 are just performance killers.

Olipro

@TomO'Connor depends how many drives you've got...

and lose "all" your data is a bit of a stretch

Dan

@DennisKaarsemaker Only a hero would use Raid Zero

Olipro

if you hit a bad sector when rebuilding, you lost that sector

Dan

@Olipro Good luck recovering from a failed RAID5 build

Tom O'Connor

14:27

@Olipro No it doesn't.

Dennis Kaarsemaker

@Dan that's why I said 1+0

or 0+1

Chris S

Called pop supplier, asked for a product list, they said "Sure, we'll fax it to your in two days". WTF?

Olipro

@TomO'Connor sure it does, it affects the probability of a bad sector when rebuilding

Tom O'Connor

If you've got 10 1TB disks in RAID 5, and you get a read-error whilst rebuilding, you lose the entire thing.

Olipro

if I have a 4 drive RAID 5, the odds of a bad sector at rebuild are lower than a 20 drive RAID 5

Dennis Kaarsemaker

14:28

@ChrisS oh, nevermind, I'll have ordered from your competitor by then

Olipro

if a drive chokes during rebuild, sure

if the drive just gets a single bad sector

you've lost a stripe

Dan

@Olipro That's what theyr'e referring too

Chris S

@DennisKaarsemaker We have them locked into a 22 year old contract... The terms are rather favorable for us. So we'll wait, but still....

Olipro

and if you've got a small scale array, assuming all the drives aren't from the same manufacturer/batch, the odds of another failing during rebuild aren't that high

Dan

With RAID5, when rebuilding you're hammering the other drives which are probably part of the same batch as the one that just failed.

Olipro

14:30

osnap

Dennis Kaarsemaker

@ChrisS ah, so they're trying to get rid of you. Cunning :)

Dan

So that's point, RAID6 gives you that resilience.

Chris S

I wouldn't put it past them...

Olipro

it gives you 1 additional disk's worth of resilience

Dan

@Olipro Yes, which is a lot as during a rebuild you have 0 resilence vs having some reslience

Olipro

14:31

if you're using drives ALL from the same batch with a large quantity of them, RAID6 could well be insufficient

really comes down to density and number of drives, as well as your storage goals

Dan

@Olipro Well, yeah, there's still a reasonable limit to the number of drives. And there are alternatives (RAID10 springs to mind), plus that's why we have backups! But ultimately, I accept the view that RAID5 isn't tolerent enough vs 6

Olipro

RAID 5 is just fine, if you have a sufficiently low number of drives and can rebuild in a reasonable space of time

Chris S

@ManuelSchneid3r Raspberry Pi - <10W. You'll have an insanely hard time getting a x86 system under 20W at the wall.

Olipro

unless you're in a situation where you can't even tolerate a single stripe being lost

ewwhite

I RAID5 with fast disks... that's about it

Olipro

14:35

odds of a drive having a few bad sectors aren't too low, odds of the entire drive fucking itself during rebuild? not hugely likely either

looks at starred comments

What the cPanel?

MothercPaneling cPaneler

Dan

@Olipro I've seen it loads

Well, back in the older days granted

Olipro

jeez, that was comic gold, go cPanel yourselves :(

ewwhite

I DO have a monster RAID6 that would make @Basil cringe.

ManuelSchneid3r

@ChrisS I have a RPi Running. But there is no SATA and hence no RAID and additionionally just 100MBit. But quite efficient with 1-3W headless

Olipro

what sort of drives are in the array?

ewwhite

14:39

@Olipro 146GB 15k disks.

Dan

@ewwhite From this point on RAID6 will be a euphemism

voretaq7

Odds of a drive having bad sectors are 100%.
Odds of a drive having bad sectors in excess of the spare block count is much lower :)

Olipro

hurr hurr

Chris S

@ManuelSchneid3r USB External HDs - And 100Mb is plenty for what you've described...

Sounds like you need to get your requirements straight, then go shopping.

ewwhite

@Dan it's huuuge

Cole

14:41

That's what she said

Wesley

@DennisKaarsemaker Don't make me cPanel all over you!

You asswagons.

3

Josh Gitlin

lmao at how someone flagged "cPanel" as offensive and not "asswagons"

6

Wesley

@JoshGitlin Buncha cuntfurlongs.

Josh Gitlin

But, at the risk of being attacked for reminding everyone, flags are really not toys...

Dennis Kaarsemaker

@JoshGitlin welcome to the comms room. Where insults are the norm and stupidity is offensive :)

2

Josh Gitlin

14:44

hahahaha

Nathan C

I'm not stupid! Oooh shiny

Wesley

@DennisKaarsemaker Douche-slingshot.

Dennis Kaarsemaker

@Wesley neh, that's hard to pronounce

voretaq7

@Wesley stop describing cPanel.

RegDwighт

I dunno, asswagon is just a wagon pulled by a donkey. cPanel, on the other hand, really does sound offensive.

Dennis Kaarsemaker

14:45

douchewaffle works better

Cole

CUNT SOCK! that's a new one I came up with last night.

RegDwighт

You are very creative.

Dennis Kaarsemaker

@Cole that... makes even less sense than normal...

RegDwighт

I will come up with a medal for you.

Cole

@DennisKaarsemaker you're welcome.

Dennis Kaarsemaker

14:46

@Cole you're approaching @Wesley levels of insanity

Cole

It's the cats.

These dual 23" monitors are sexy

Jacob

@Cole Did you get new ones?

Cole

@Jacob yeah work got me 2 x 23" widescreen monitors

Because I'm awesome.

Josh Gitlin

Ah ha it was you @Jacob who flagged cPanel as offensive, amirite? ;-)

Jacob

@JoshGitlin actually no, I considered it.

Dan

14:49

@ewwhite Yes, your mother mentioned

Dennis Kaarsemaker

2

Cole

yup

Josh Gitlin

@Jacob haha. How's life been?

Dennis Kaarsemaker

@JoshGitlin no, that was @Wesley's nemesis

Cole

Who has a rotating on-call schedule here?

with more than one person on call at a time.

Dennis Kaarsemaker

14:51

@Cole me.

Jacob

@Cole I bought 2 of these for University on sale for 160 a piece, they're brighter than the room light.

@Cole me

Nathan C

I'm glad I'm not. Then again, we're not a 24x7 shop anyway.

Jacob

@JoshGitlin I just started attending University at WVU Tech NOT WVU after graduating HS early. WVUTech.edu

Josh Gitlin

Congrats! Enjoying it so far?

Tanner

@Cole We started one about a month after I got here. Unfortunately, we never decided who was on call first. The schedule is rotating, but we're never sure whose turn it is.

Fuck you Verizon for not allowing symbols in passwords.

Jacob

14:55

@JoshGitlin Class hasn't started, so yeah why not.

ewwhite

@dan Huuuge...

voretaq7

@Cole more than one person?

Cole

@voretaq7 we have 3 people on call

1st, 2nd, and 3rd.

voretaq7

why would you have such a situation? The point of on-call is so that the rest of your team can sleep.

Cole

@voretaq7 in case you can't reach the first or second person

Tanner

14:58

@Cole wait, wat?

Cole

Plus not everyone is cross trained

voretaq7

@Cole If you have enough people to have 3 deep, have a primary, a backup, and an off.

Cole

We're supporting 80 sites here.

voretaq7

@Cole then cross train them.

Cole

@voretaq7 lol.

Dennis Kaarsemaker

14:58

@Cole err, you're doing it wrong. You should always be able to reach the primary on call

Cole

riiiiight

voretaq7

There is no valid reason for the whole company to be "on call"

Cole

@DennisKaarsemaker that doesn't happen.

@voretaq7 there's 5 of us

Dennis Kaarsemaker

@Cole then make it happen :)

voretaq7

@Cole then fire them.

Cole

14:58

3 on 2 off. They're not going to change it

voretaq7

You're on call, you're available.

Dennis Kaarsemaker

in helpdesk, supporting all the remote offices, we have 1 on call

voretaq7

@Cole Like @DennisKaarsemaker said, you guys are Doing It Wrong

Cole

@voretaq7 i agree, but not so much here

Dennis Kaarsemaker

(120 offices)

Cole

14:59

We have a 24x7 help desk

voretaq7

I'd quit.

Dennis Kaarsemaker

in production, supporting beeelions of euros, we have one on call.

Cole

We don't get a lot of calls I should say, apparently only when I'm on call do I seem to get calls.
