5:00 PM

hits @Iain and @MDMarra with the hose Stop that or I'll have you both fixed!!

@WesleyDavid Just because YOUR balls are in a jar in some vet's office...

Yeah, but I'm not bitter.

Actually, no, I am.

So, we have a DR contract with sungard where they host our DR servers and also give us workspace for up to 150 people in the event that our building is destroyed/maimed/whatever

@WesleyDavid no you're not, that's just the stuff we spray you with to keep you from eating your fur and gettn' hairballs.

I just found out that the workspace is not guaranteed to be in Philly, only the servers

So there's a good chance that the non-ops people will be shipped to atlanta, chicago, or LA if there's a disaster from the hurricane

Michael Hampton

5:02 PM

Isn't Philly right smack in the path of this hurricane?

Ya

Michael Hampton

And where is the primary site?

philly

opposite end

Michael Hampton

Hm. I'm not sure someone completely thought this out...

The DR site is on the 11th floor with super duper redundant everything and generators hooked up to natural gas lines as well as aux generators that can be fed if the gas lines break

Michael Hampton

5:05 PM

@ewwhite So in my kickstart I have repo --name="vmware-tools" --baseurl=http://packages.vmware.com/tools/esx/5.1/rhel6/x86_64 and in %packages I have vmware-tools-esx-nox. Seem reasonable? It's working fine so far, as far as I can tell...

@MDMarra Suppose ground level is flooded?

@MDMarra Wait, what? This one???

Then we have one of those cool underwater fibers that you hear about!

@ErnieTheGeek ...swing and a miss. You actually don't seem to get what we're saying. This is not something you do with DNS through your registrar's control panel. This is something you configure in your webserver, whether it's Apache, IIS, or other. — HopelessN00b 40 mins ago

@MichaelHampton I'm not saying it's the best site by any means - I've only been here for a couple of months. But if the whole city is literally under enough water that ground level is covered, no one is going to be able to get out of the city and get to the DR site anyway

@HopelessN00b ya, just as an example

Michael Hampton

Probably not. I'm just thinking about how parts of NYC flooded last year.

5:07 PM

yeah

NYC is also right on the water

Lucky them

Michael Hampton

Yeah, Philly's set back a bit, right?

There's still the schkukhill river (or however the fuck you spell it) but that flooding wouldn't endanger both sites

Michael Hampton

Ah, okay.

@HopelessN00b The problem is that some DNS regitrars actually provide URL redirection as a service. Basically they adjust DNS to point at some web server at the registrar that does the redirect. Ernie might believe this is a common or 'normal' feature.

I doubt flooding of that nature would be a problem, the issue would be if both sites lost power for extended periods of time

Michael Hampton

5:09 PM

Stupid-as-a-Service.

@MDMarra I dunno what to say, then. That's not rude, that's... factual.

I dunno how long they could feed their generators - but that's why we have contracts with them, let them worry about it

that's weird- I didnt touch the page, but when I came back to this tab, I had been logged out

@HopelessN00b The first two lines didn't need to be in there

@MDMarra when does the hurricane land ?

Michael Hampton

5:10 PM

Heh, good enough. Just when there's a hurricane, you usually want to be a couple hundred miles out of its path...

I mean, I can dig up other examples if you'd like

@Iain Supposedly it will start Sunday night and really get started on Monday

@MichaelHampton Yeah, and all of our branch offices are designed to be able to operate with us down

Michael Hampton

And pray it doesn't make landfall there. 11th floor + hurricane = flying shards of glass.

@MDMarra Well, given that he'd already missed the point twice, it seemed that pointing out that he was missing the point might be useful.

So our testing centers can continue to operate and rake in the cash

@voretaq7 what is this?!

5:12 PM

@David idunno dude that's from yesterday

my memory tapes don't go back that far.

@MDMarra If you want. Just trying to understand this... odd... definition of "rude" you (y'all?) seem to have. I mean, by the same token, your line saying "this is a terrible question" at the start of your answer was rude and unnecessary...

@HopelessN00b does have a point there, @MDMarra :)

Thats fair. I didn't say that I was perfect.

To be clear, I don't think that was rude or unnecessary, but by the standard you're applying to me... it is.

Michael Hampton

@HopelessN00b For truly bad questions I don't comment at all. Just vote to close, and maybe downvote. For questions where the person wants to DO something bad, then I may explain that what they want to do is a problem.

5:14 PM

But that doesn't minimize the fact that you could have just explained to Ernie why he was wrong instead of saying "...swing and a miss" and then not actually explaining where his misconception was.

@voretaq7 i wasnt even here yesterday...

@HopelessN00b I pointed that out to you, because I've flagged probably at least a dozen of your comments in the last week or two so it sticks out in my head, and I never flag comments.

Q: How to generate build no with SVN revision no & Maven buildNumber plugin

I am using mvn buildNumber plugin to generate build no with latest svn revision no. But, our version is not resolve to ${buildNumber} in the duration of installing in .m2 local reposotry. here is the our pom details: <modelVersion>4.0.0</modelVersion> <groupId>com.hp.cloudpr...

package-management scm

WTF?

@David idunno, probably a fucked up tab complete

@voretaq7 it was actually wednesday

but over 7 hours after i left work

5:19 PM

@MichaelHampton never tried that. Nice, though.

@MichaelHampton is there an RPM for that repository?

@MichaelHampton Well, maybe that's the difference. Seems ruder to me to just "punish" and ignore someone than to tell them what they're doing wrong.

@MDMarra Alright, well... like I said, this is me being nice? If you wanna point out comments you think are flag-worthy to me, might be more useful in providing a feedback loop. Hard to change when you don't know what needs changing.

Michael Hampton

@ewwhite Um, maybe?

@MichaelHampton or did you create the repo file?

@David then my tapes definitely don't go back that far :P

Michael Hampton

@ewwhite The docs say to create the repo file yourself.

Better add that to my kickstart...

5:23 PM

@HopelessN00b You can tell someone in a constructive way and you can tell someone in a dickhead way. The point of Stack Exchange is to help people and share knowledge, not to prove that you're smarter than people asking questions. We're all rough around the edges - it comes with the job. Some of us have a nicer disposition (@Iain) than others (me and you), but we all needs reminders of why we came here in the first place.

Michael Hampton

Oh wait, no that's going in puppet.

Trust me, I was considered the "asshole" around here for a lot longer than you've been a member. I'm not saying anything to you that hasn't already been said to me.

Just trying to be constructive, that's all.

@MichaelHampton Yeah, get kickstart to feed it to puppet then get puppet putting the repo in place then installing vm tools based on the virtual fact :)

Michael Hampton

@ShaneMadden I'm in the middle of figuring that out myself. Problem is, I have some boxes on VMware, some on Xen, some on KVM...

@MDMarra Alright, well, if you see any more rude comments by me, I'd like you to let me know (in addition to flagging if you'd like), so I have a feedback loop.

5:25 PM

Works for me

@MichaelHampton Not sure about how good its hypervisor detection is for Xen/KVM, but the virtual fact is set to vmware under VMware products, so you can do a case statement to do stuff based on the virtualization platform the system's in

Michael Hampton

@ShaneMadden facter picks them up just fine. Mainly I need to get around to it.

have any of you ever completely changed your email address?

@ewwhite Not since I was in high school

I mean, I'm holding onto an address from 2000 or so

chubbylover13@aol.com?

2

Michael Hampton

5:29 PM

I've done so, but not in a long while. My current email dates back to 2004.

Wow, it's a party in here! Look at all the active people.

@ewwhite ...thought I deleted that from everywhere

Damn, should have used the Homer Simpson address... chunkylover53@aol.com...

Quick, someone say something flagworthy then we can have The Drop Of The 10k's and The Blues as everybody rushes to see what the flag was a bout.

@ewwhite I have to laugh... When I signed up for my first e-mail address (from AOL no less) in 1995 I picked one based on my real name (mostly from lack of imagination or naivety). Over the following years I started using crazy pseudonyms until a few years ago when I returned to using my real name. What goes around comes around?

5:33 PM

I really thought I'd hit 40k. This last minute hurricanepocolype planning is throwing a kink in my style

@pauska Wut?

Michael Hampton

My first email address was assigned to me, and had my real name, and a % in it.

So let's say I wanted to phase-out my mac.com email...

THere has to be an efficient process.

@ewwhite Put a signature on your new email that says "I've recently changed my email address to _________. Please update your contacts"

@ewwhite I dunno about "change," but I abandon old ones and/or create new ones every so often.

5:34 PM

And also send an info update to all of your contacts

Michael Hampton

@ewwhite I've wanted to phase out my current primary email for a couple of years now, mainly because the spam is almost unmanageable. I still haven't actually come up with a good process to actually do it.

Then just put a forwarder from your mac.com to your new one for a while

@MDMarra Then forward it for a while, then delete or ignore the account.

yep

My forwarder is part of the problem. Apple's icloud forwarding is sketchy.

5:35 PM

Even better, put a forwarder and an autoreply on the old one and have the autoreply notify the sender of your new address

@MDMarra That's what I do... All my e-mail addresses get forwarded to my One True E-Mail. Then I forget about the account for a few years until someone uses it.

@ewwhite Use getmail or something like that to fetch your e-mail and aggregate it to a single account.

I run my own exchange and have spam filtering, etc. It's just that I've been @mac.com for so long...

@MDMarra Right, may as well make sure the spammers know where to find you. =D

You know it

That's my secret for never running out of cheap penis pills, or contacts in Nigeria. :)

5:39 PM

I get extremely little spam once SPF, DKIM, and DNSBLs get through with the incoming horde.

@ChrisS You... throw letters at the spammers? Fight fire with fire, I like it.

22

Q: How can I attract more Spammers hitting my Spam traps?

Currently I have a number or domains that are set up as Email Spam traps. So if I get mails on that domains I can be certain that it is ~100% Spam. I'm using this information to temporarily defer message delivery from spamming IPs on my real Email domains. I can also use the Spam mails to improve...

@MDMarra Heh, I like the deleted answer best.

serverfault.com/a/320150/118258

haha yeah, I remember that when it was posted

so great

Hmmm... so a storage-Vmotion. Any reason why someone would keep the disk in the same format as the source, when the source is a thick provisioned disk?

5:47 PM

@HopelessN00b I thin-provision everything these days

but no, I can't think of a reason

@ewwhite Yeah, that's what I'm thinking, but all these old VMs are tick provisioned. With lazy zeroes.

@ewwhite mornin' gents.

@HopelessN00b Supposed to be thick on the client and thin on the storage end, right?

@ewwhite Well, gimmie a minute, I'll try this on a box I don't care about and see if I can find a reason. IUt's only production, so what could go wrong?

@HopelessN00b Are you sure it's not on a thin LUN?

That's sort of the more common way

Thin LUN, thick lazy VMDK

@MDMarra Old one sure isn't. May as well check the new one first, but I doubt it is either. (Sadly.)

Oh, sweet Jesus, someone did something right around here! Nice.

SysAdmin1138 Expounds: Big-ass storm preparations

posted on October 26, 2012 by SysAdmin1138

As of the latest guidance, Hurricane Sandy is not likely to directly cross the DC area. That said, hurricanes are pretty large storms so it's likely we'll catch a piece of it. How much of it is unknown at this...

@Sysadmin1138Expounds So, follow-up question. How can you tell ahead of time when your ass-storm is going to be big?

@HopelessN00b Directly correlates to the Size/Price ratio of your lunch?

@ewwhite You got a direct link for that job you were talking about? I couldn't find a careers-related link on their page.

@Adrian naw

I actually don't like this answer...

1

A: RAID10 without write-back cache = horrible write performance?

The performance in real world applications will vary, due to the nature of the application. Asynchronous writes will go to RAM, while you have any available for write buffering. Obviously writing to RAM will be significantly faster than to disk. This is the default for most (all?) modern operati...

@freiheit Mbe, but would have to account for other factors, like content and ethnicity of the lunch in question.

6:01 PM

I'm thinking that's a poorly-written answer as he seems to be using 'application' in an ambiguous fashion.

I think I understand what he's talking about, but it wouldn't necessarily be clear to people with less experience.

@HopelessN00b I was originally going to say "burrito" instead of "lunch", but felt that was both unfair to that particular cuisine and possibly too regional

@freiheit I think having a burrito for lunch all but guarantees a big-ass storm anyway. So not unfair or regional, but... redundant.

The giant burritos I'm familiar with in the SF Bay Area are an SF-variation on an LA-invented food, with very little to do with the mexican origins...

@freiheit Yeah. Taco Del Mar kind of thing, eh?

@HopelessN00b In my experience, it really depends on the burrito place...

6:05 PM

@freiheit Well, there's the Chipotle spectrum and there's the La Bamba spectrum...

Clearly you have a more... varied... burrito experienced than I'm used to.

Heh. Installer for Ubuntu 9.10 is faster in a VM than bare metal.

Something to be said for CPU management in VMWare.

9.10? That still exists?

@HopelessN00b There's a lot of places around that have a Mission-style "Super Burrito"... The best local mexican food comes from trucks, though.

@ShaneMadden Not really, but it's what we still have in production. I'm under directive to extend its usefulness with a hand-compiled Firefox until we can roll Windows out in the next year or two.

At this point, I do what I'm told.

6:09 PM

@Adrian Ouch. Hasn't gotten a security update in a year and a half, right?

I'm done rescuing him from the consequences of his decisions.

@ShaneMadden Something like that. Our DBs run on Debian Lenny which doesn't get them either, not that my Devs ever bothered with security updates.

But considering that our public-facing websites are on FC7 and FC8, it's not the worst thing we have going on.

@Adrian Yeah, getting out sounds like a good plan.

I'm just annoyed that I know my boss is going to blame it all on me after I leave.

Decent odds that I'll get a phone in 3-4 years asking me to come back and do his job,

@Adrian To be fair to your Devs, there's little point in applying security updates when you don't sanitize your SQL inputs. So, they have a point. When you think about it... that way.

@HopelessN00b This is true. No prepared statements from what I can tell in the error messages I receive.

But I hate PHP so much that I've never bothered to checkout a copy of the code to find out.

I do know that a single quote in a staff last name broke the DB up until a few months ago. I guess we don't hire many Italians.

6:14 PM

Wow, my employer's choice of networking equipment for the upcoming refresh seems to have made it into networkworld. twice.

@Adrian Or Scots, or Irish, or...

@HopelessN00b yeah. And I don't think the Devs know enough to use anyone else's libraries for things like searches. They almost always roll their own.

Of course, that's not an uncommon problems with Devs.

Why does every stupid programming language abbreviate else if differently? Python, elif, c else if, ruby elsif php `elseif, it drives me nuts....

@Zoredache Because programming languages are developed by developers, duh.

2

Michael Hampton

@Zoredache Me too. At least PHP lets you use either elseif or else if

6:23 PM

@Zoredache Ruby's elsif is so dumb

ugh... @voretaq7 This interview is occurring over Skype...

Well, the candidate on Skype...

So much for someone else doing something right around here... turns out that storage-vMotioning running machines with snapshots isn't supported. Guess what our BES server's been using as a "backup" before making config changes? For years... sigh

my coworkers are in a conference room

and I'm on a conference bridge from my house to the conference room

@Zoredache When I was doing the Ruby track on Codecademy and got the else-if section, I got stuck for a good while with code that wouldnt run and I couldn't figure it out forever lol, until I realized it was spelled elsif

@HopelessN00b Delete all snapshots!

6:26 PM

@David Well what really gets me is when I am working on my puppet manifets(ruby style) and then I switch over to writing a bash or python script for something else. Switching back in forth drives me nuts, and I often have to keep the stupid language guides open for the stupid if/wtf/else construct.

@Zoredache Oh yes. I hate having to do that. Makes my brain hurt.

@ewwhite oy

on a bad wifi connection too?

@voretaq7 and a wet sock on the phone handset...

@ewwhite -10 points

When I speak, the people in the conference room need to translate for me.

Oh, and the candidate is british.

(muddled accent...)

6:33 PM

@ShaneMadden ...which is most efficiently accomplished by deleting this .vdmk file I see, right? :)

@HopelessN00b Sounds like a plan.

I'm embarrassed.

@HopelessN00b Delete all the files, just to be safe

wifi dropped

Definitely. It's the BES server, so safety is definitely priority #1.

So I probably go through our backups and make sure to delete all the files I see for it in there too, right?

6:36 PM

@HopelessN00b Do you have access to a bulk eraser?

@voretaq7 I think he hung up.

we're getting voicemail

@ewwhite Best interview ever?

it's rough, man

@freiheit No... but we have a mop bucket and some cleaning supplies. I should probably but the disks in there, and clean the data off with ammonia, right?

@ewwhite So, still hiring for that position, huh?

@HopelessN00b That sounds like a good start. Are their offsite backups of some sort? Make sure to get to those, somehow...

6:41 PM

@HopelessN00b this is for another senior engineer.

@freiheit We have an Avamar D2D system, so I just need to make sure to wash the drives at our colo site too, I think.

@ewwhite Jeebus. Is this for a real senior engineer, or the type of senior engineer that most places hire for (5 years experience type of thing).

@HopelessN00b No kidding, eh? Because they don't want to pay for the guys with 20.

Honestly, I want to work under an actual senior engineer. Learn a pile of good shit that way.

@Adrian Amen to that. I'm probably most of the way there myself, but I'd love to work under another guy who's got as much IT experience as I have... "being a live" experience. Like a free boot camp on... everything IT and job and career-related.

@HopelessN00b work for me

@HopelessN00b yeah, that's why I'm not terribly interested in these "You own all aspects of IT for our company" positions.

On-call 24/7/365 indefinitely is not worth what most companies want to pay.

6:46 PM

@Zoredache i hate this, except I run a Win7 VM on my iMac

switching between Ctrl and Cmd is terrible

Hmmm, live blogging an interview

I'm watching the internet collapse

@voretaq7 because my DNS doesn't work?

its kinda fun :)

@voretaq7 ay ?

@ewwhite you got him back on then ?

6:49 PM

@ewwhite because there's all sorts of funky going on with the north american backbones for some reason that has yet to make it to my ears

@Adrian Pansy

@ewwhite I'm warming to the idea, lemme tell you. I wouldn't be surprised if I end up shooting you a resume in several months, on account of... "stuff" here. I think they expect to convert me to FTE so they can get 60 hours a week and 24/7/365 support for under 100k a year. Hah!

:)

@Iain yeah... it's still bad. It makes us look bad.

@Iain it all started with tumblr being down....

6:49 PM

@JeffFerland Naw, I'm just old dude. That crazy shit is for young guys who have no immediate family.

@HopelessN00b can get you closer to $115k

and (briefly) youtube

@ewwhite Yeah, I believe ya. Still not gonna be the one to leave the team here in a lurch. Let management do that when the time comes. :)

@HopelessN00b but you won't get rich making $115k.

@ewwhite how much stress? :)

6:52 PM

@ewwhite I'd settle for Comfortable at 115k. Your mac.com email address still work?

Low stress, except for the Supermicro stuff.

possibly an issue with inertia and getting newer solutions in place.

@ewwhite why is supermicro stressing you?

anyone got sshd installed on windows handy ?

@voretaq7 3am calls because of broken stuff.

@Iain the daemon? nope

6:54 PM

@Iain Odd. Just seeing that pop on the screen makes my skin crawl.

@ewwhite redundancy?

@ewwhite Meh. If I was looking to be rich, I wouldn't be in this career anyhow.

@Iain The horror.... Would you talk to your mother that way?!

-2

Q: How can I check SFTP is running on the server and listening

I configured SFTP on windows server by following this link http://www.xenocafe.com/tutorials/windows/openssh_sftp_server/index.php. But even after setup I am not able to connect to SFTP port on this server. How can i find configured SFTP port and access it?

windows port sftp

@Iain Got it now, or has gotten it in the past? And what version family we talking about here?

I mean, I might know a guy who did it in the past, on Server 2k3, under protest.

6:56 PM

@voretaq7 software RAID crapped out

the answer is probably NARQ but I guess it could also be check the ListenAddress in sshd_config

@ewwhite redundancy? (Y U NO HAVE 2 SERVERS?)

@voretaq7 there were several behind a load balancer.

@Iain If you're too Linuxy for netstat, sure.

@Iain "Make sure it's listening and SFTP is enabled"

@ewwhite so no problem then.

6:58 PM

but what was supposed to be a simple disk replacement turned into hours of server downtime... not application downtime

and I was called because the software RAID wouldn't resync...

so yes, problem

That's the problem with cloud stuff... we can make things highly-available... but it's really just displacing the work.

@ewwhite yes, the problem is you were called...

@HopelessN00b he used netstat and it's only listening on 127.0.0.1:22 but I don't know how sshd on windows works

When people call and stuff isn't down that's a problem
