@MichaelHampton: I primarily have it so that at some point, I can stick AAAA addreesses on resources I need outside and either tether an ipv6 capable phone (alas, starhub dosen't do mobile ipv6) or stick a tunnel on it so I can access stuff.

faker

apparently these number are from the last campaign they ran

Michael Hampton

Gawd. I can't imagine what you'd have to do to Magento to make it actually serve 250 simultaneous users.

@JourneymanGeek A bit behind the times, eh? I already have several things with AAAA records that point into my home network. And have done for years.

faker

they don't use Varnish, just directly served -- from Apache! Without fpm-php -- mod_php! My god...

Journeyman Geek

@MichaelHampton: I haven't really needed it

Michael Hampton

@faker You're going to have a fun week!

Journeyman Geek

12:05

@faker: 0_0. I suspect the setup on ~~my phone~~ old mini server is probably somewhat better set up for that

faker

@MichaelHampton I bill them by the hour :D

@JourneymanGeek well, honestly that setup is good enough for their normal traffic

Michael Hampton

Back about 10 years ago I got my Pentium 166 slashdotted. It mostly held up, sort of.

RobM

always fun to reply to users who have demanded satisfaction from a senior tech support person because their "remote worker" desktop session isn't right and that clearly must be something our helpdesk is doing wrong with "Actually, you were typing in your username incorrectly".

MichelZ

@RobM yeah, users....

Journeyman Geek

@MichaelHampton: I'm pretty sure a pentium 166 was a museum piece 6 years ago.

Today's gem from the spam mailbox:

Subject: The Benefits of Running IBM PowerLinux Solution for SAP

hilmanshini

hello

Michael Hampton

12:23

@JourneymanGeek Oh yes, it was ancient even then. I tossed it in a nearby dumpster not long after that.

MichelZ

@hilmanshini hello

Dennis Kaarsemaker

Fuck IBM. Fuck SAP.

MichelZ

@MichaelHampton you really should consider recycling

Dennis Kaarsemaker

@JourneymanGeek it was a museum piece 16 years ago..

hilmanshini

err anyway how downvote system works?

MichelZ

12:24

@hilmanshini we downvote everything with JAVA in it, yes

Dennis Kaarsemaker

@hilmanshini you vote down, you lose rep.

hilmanshini

-_-

Journeyman Geek

And I mainly need external access for stuff like ttrss (I run that on a VPS). My rtorrent/rutorrent system has ipv6 as well, but that's for hipster seeders, and I'm not sure my rtorrent supports it

@hilmanshini: Yanno, there's this thing called the help page...

hilmanshini

wherisdat?

no just asking

Its a great way to download linux livecds nonetheless ;p

hilmanshini

oh ok then

so downvoted made from user not systems

ok then .

okies then

Journeyman Geek

@DennisKaarsemaker Yeah, that ;p

hilmanshini

okay then

Journeyman Geek

Though I should probably have said 10 years ago. Damned dyslexia.

hilmanshini

12:28

and why you downveted anything about java?

@MichelZ

is the java haunted you?

Dennis Kaarsemaker

23 hours ago, by Falcon Momot

> The additional security surface java puts into your environment is complex, and it's important not to ignore it or try to simplify it away.

Firstly, there is the horrible record the JRE has for having security bugs. It's hard to point out a specific one, and this is the scary part - the bugs are overwhelmingly unspecified vulnerabilities with unspecified vectors.

When I, as a security consultant, read clauses like "allows a remote attacker" without further qualification as to their meaning, I see that it could very well mean that certain parameters getting into a certain function might…

hilmanshini

i dont believe that happens

how can that happens with what protocols? RMI?

MichelZ

@hilmanshini java haunts EVERYONE

hilmanshini

it feed me everyday

why it haunt?

MichelZ

because java is a lame piece of shit

hilmanshini

12:31

yea that can be

javanese

MichelZ

it's full of securty flaws and it's extremly slow

and impossible to properly maintain (on windows)

hilmanshini

btw java has an island now

MichelZ

we are talking about the programming language, not the island

hilmanshini

haha yea kidding

MichelZ

I guess everyone is aware that there's an island called java

Michael Hampton

12:33

@MichelZ Isn't that where coffee comes from?

Journeyman Geek

I was under the impression it was named for coffee from there?

Now you're just being silly.

Dennis Kaarsemaker

that can't possibly be misinterpreted...

Michael Hampton

Well, then.

And that is what I think of that.

Journeyman Geek

and eh, the only reason I have java installed is minecraft.

Michael Hampton

Java is the reason I have never played Minecraft.

MichelZ

12:37

adobe should buy java and then we can nuke them both out of the orbit

Dennis Kaarsemaker

The only reason I have java is the iLO remote console.

I should reverse engineer the protocol and write a client in C.

Dennis Nolte

@DennisKaarsemaker add DRAC .. same shit different provider.

Dennis Kaarsemaker

I have no dells \o/

not in the dc at least

Michael Hampton

Isn't there already a standard protocol for that?

Dennis Kaarsemaker

@MichaelHampton I tried a vnc client, but that didn't work :)

Basil

12:52

morning

Dennis Kaarsemaker

@Basil hi!

Michael Hampton

Oh...there's a standard protocol for serial console, but doesn't seem to be one for a graphical console

Dennis Kaarsemaker

@MichaelHampton if I just want text, I can just ssh to it and use textcons

which, tbh, is enough in 99% of cases. I haven't actually used the gui remote console in months

ewwhite

textcons is good

It took me years to realize it replaced remcons

Q: smartctl error end_request: I/O error, dev sdb, sector

I have a Scientific Linux 6.5 server with a RAID with SSD disks. I see several error on dmesg file but there is no alert or errors provided by the utilities of the RAID controller (LSI controller). The server is a Supermico D20-4x-M4, connected directly using Infiniband to a storage server with ...

is it just me or are those drives directly connected and not using the raidcontroller

Journeyman Geek

13:04

superuser.com/questions/804666/… <--- is this more SF territory?

RobM

@JourneymanGeek I'd say so, yeah

ewwhite

@DennisNolte basically, yes

The server is a Supermico D20-4x-M4, connected directly using Infiniband to a storage server with the SSD RAID. The controller is LSI MegaRaid SAS 9286CV-8e. And the disk are SAMSUNG MZ7WD120.

Dennis Nolte

13:19

@ewwhite so are those devices "behind" the hardware raid or not?

Dennis Kaarsemaker

13:41

@ewwhite that's not your fault. It was missing for years.

ewwhite

@DennisKaarsemaker oh, so I wasn't crazy?

@DennisNolte I can't tell. Likely not.

Dennis Kaarsemaker

@ewwhite I didn't say that :)

@JourneymanGeek YOU ARE A BAD PERSON AND YOU SHOULD FEEL BAD

Nathan C

@Basil Burn the mp3 player/computer/whatever it is

Journeyman Geek

Basil

@NathanC It is a rather expensive mac ;)

Journeyman Geek

@Basil: Gundam style?

So giant japanese robots fighting music?

MikeyB

14:12

@MichaelHampton Yeah it's all good.

MichelZ

gangnam style?

Basil

Uh, yeah, that

ok, I clearly need more coffee

MikeyB

@Basil Gundam style would be pretty cool.

Basil

brb

@MikeyB in my defense, that's exactly what it sounds like when they say it

Michael Hampton

@MikeyB We've been trying to figure out if you really meant Celsius.

MikeyB

14:14

@Basil Weak, but:

Basil

@MikeyB oh lord

MikeyB

On second thought, no that doesn't make sense and then I remember that APC's developers are retarded:

The columns don't line up - sorry it got up to 52℃

Journeyman Geek

Hot, but not facemeltingly so?

MikeyB

Yeah. Also: damn we need to change the taps:

Bob

@MikeyB ...that makes far more sense :P

MikeyB

14:27

@Bob Now that I'm mostly awake... "Oh yeah... that's kind of overly hot."

Nathan C

So, riddle me this:I have two identical APC PDUs and attempted to hook them up to an APC Smart-UPS 6000. I was able to connect one perfectly fine into a 20A socket, but the other one wouldn't fit in either the 20A or 30A plug. Any idea why?

But yet, I have two 20A plugs in the wall for these PDUs and they both fit.

Basil

So my new acquaintance at IBM Switzerland thinks that a lack of a formal university education might hurt my chances of finding a job there, should I ever go fishing for one...

but on the plus side, both Netapp and HDS are huge, at least in the accounts he works with

ewwhite

14:44

@NathanC L5-20?

NEMA 5-20?

I mean, it should be very easy to see why the plug doesn't fit.

Nathan C

@ewwhite 5-20 for both. The one that doesn't fit is plugged into a 20 amp

ewwhite

How doesn't it fit?

this should be pretty basic :)

Nathan C

@ewwhite One of the teeth is slightly off...by maybe a quarter inch

ewwhite

bent?

just bend it back

Nathan C

I can't experiment much since the PDU's connected to our core switches :[

@ewwhite Nope. Tried that.

I spent literally 10 minutes trying to get the dang plug to fit, but no dice.

Then I had to plug it back into mains so people could work... :(

ewwhite

14:51

for your Euro, APAC folks, we're talking about...

So what's bent?

Journeyman Geek

o0

It never fails to confuse me that you guys use such puny plugs

Nathan C

Oh, I guess I didn't understand the plug we were talking about, lol. Mine's a twist-lock.

ewwhite

Nathan C

That ^

ewwhite

@NathanC That's an L5-20 (L == locking)

Nathan C

14:54

Sorry, noob at the whole power thing...never usually have to deal with them. :P

ewwhite

@NathanC So the ground on that sets the orientation...

Nathan C

The unmarked slot in the diagram is the one that's off by just a hair

@ewwhite Right. It can only fit one way.

ewwhite

bend it

Nathan C

@ewwhite Can't bend it left or right...it's almost like it wants to be twisted just a little more, but it doesn't work. ha

ewwhite

Take a pic

MichelZ

14:56

@NathanC buy a new cable

:)=

Nathan C

@ewwhite Can't unplug it :( it's a production PDU powering our core network switches

ewwhite

so it doesn't fit, but it's plugged in?

Nathan C

@ewwhite It's plugged into a socket in the wall that's exactly the same thing, and it fits

but it doesn't fit into the plugs on the UPS

Trying to get my pics on google drive so i can show you >.>

ewwhite

flashlight, check debris...

Nathan C

This is the back of our UPS

MichelZ

14:59

blog.fox-it.com/2014/08/27/…

Nathan C

There's one PDU plugged in...and it works fine.

MichelZ

Isn’t it ironic getting a Java exploit via java.com, the primary source for one of the most common used browser plugins? Current malvertising campaigns are able to do this

hahahaha

Nathan C

@MichelZ Lulz

ewwhite

@NathanC most of those look like L6-20/30 plugs

Nathan C

Get pwned while trying to update!

ewwhite

15:00

208V

Nathan C

So, that?

ewwhite

it's printed on the plugs

Nathan C

Let me see if I can get a good look at them...

ewwhite

the diameter of the prong circle is what's different between 120V and 208V

or give the model of the PDU

AP89xx?

Dan

What's the obsession with disabling ICMP internally FFS

ewwhite

15:04

@Dan doesn't the windows firewall do it by default?

Bob

@MichelZ Java is the exploit.

@ewwhite Dunno about Windows, but Norton's firewall sure did.

Dan

@ewwhite Dunno

Probably

Nathan C

@ewwhite You were right. One's an L5-20, the other's an L6-20

They're the same model, but they can be configured differently when ordered...so yeah. We inherited the equipment so we had no idea.

We're gonna look at replacing the PDU with one that works or rewiring the room so the UPS can power all the outlets instead.

Journeyman Geek

@Bob it does

Nathan C

Or get an adapter. Depends on what'll be cheaper in the end :p

ewwhite

15:19

@NathanC no adapter option

what model number?

Nathan C

@ewwhite Smart-UPS 6000

ewwhite

@NathanC Of the PDU.

Nathan C

Oh, right...sec

ewwhite

There's a model number... AP79xx

Falcon Momot

@Jacob not in the US, no... I have a few in Canada, but that won't help you.

Nathan C

15:54

@ewwhite I don't see one anywhere. The issue is a plug mismatch ...we'll figure out a solution. :P

We can use a standard power strip since all the equipment isn't even pulling 4A total, so it's not a huge deal.

(Obviously it won't be an el-cheapo power strip, but you get the idea)

Erm which bit of the error message did the OP not read serverfault.com/questions/625046/… ?

Ry Jones

@Iain that's an impressive amount of not reading

Iain

This is pretty galaxyzoo.org.s3.amazonaws.com/subjects/standard/…

@RyJones yah if it's one line lost in amongst lots of others then ... but ...

Ry Jones

@Iain I mean, it's right there.

Tom W

@RyJones having never used mysql, the first thing I'd want to know is what a PID file is - and the man page doesn't mention those at all

I get the impression OP doesn't understand the message

Iain

@TomW he's updated it look at Revision 1

Tom W

18:34

I don't either, tbh.

Ry Jones

so it looks like it isn't installed, right?

yum doesn't show it?

Iain

@RyJones could have done a source install which would be compatible with /usr/local

Ry Jones

@Iain of course you're right. I assumed he was running yum because that's how he normally manages packages.

actually, this is almost certainly on a webhost, right? it shows cpanel in there

Iain

@RyJones all bets are off then !

ewwhite

having drapes installed...

I feel like a grown-up.

@ewwhite curtains ?

they have one server at Hetzner. Running Magento. On Apache. With mod_php. ffs.
