@ewwhite Is it remotely worthwhile to add SATA SSDs for L2ARC in a home server?

@JoelESalas Depends on what the home server is doing.

Q: How do I view my website stats via cmd line?

I use Wordpress for my website. Is it possible to use SSH or such to view the stats on my website? Via cPanel, I can see latest visitors, logs and errors. I just want to be able to view them via command line (more geeky). I am using the latest OS X.

ewwhite

But possibly, yes.

Shane Madden

I just want to be able to view them via command line (more geeky) .. ok?

Jacob

@ShaneMadden Lynx? :)

Michael Hampton

12:11 AM

If you want to be geeky, don't rely on cPanel and set up a server the same way the rest of us do? :) — Michael Hampton 5 secs ago

Shane Madden

@Jacob I'd upvote that answer.

Mark Henderson

@MichaelHampton Must I remind you?

Oct 19 at 16:50, by Iain

On a serious note guys, can we stop the BOFHish/snarky/sarcastic comments on the main site please. If you can't say something politely then it's much better that you don't say anything at all.

Joel E Salas

So our corporate IT team decided to "update certificates" on our vCenter Server (we don't control it directly)

Mark Henderson

The actual cpanel part of the question is irrelevant, and you know it, he'd have the same issue if it was cpanel or not

Michael Hampton

Eh, it got the necessary information out of him. He's on shared hosting.

Joel E Salas

12:13 AM

Result: All host and VMs disconnected, have to reconnect them manually

WesleyDavid

@JoelESalas Good exercise. Builds character.

Jacob

@ShaneMadden done, minus snark

Shane Madden

@JoelESalas Yeah, of course... they weren't expecting that?

Adrian

Well, that was the most fscked up meeting I've ever had to attend.

Shane Madden

@Jacob Nice.

Michael Hampton

12:18 AM

@Adrian They expect you to pull off another miracle with no funding?

Zoredache

@Adrian You have too many meetings. It sounds like you have 2-3 a week, and each one they decide to do something different.

Adrian

@MichaelHampton Oh, that's old hat. I had the joy of trying to convince my boss to something I don't want to do and convince him that it would probably be a good idea to lay me off to get it done.

@Zoredache I have 2-3 on Mondays. The rest are spread out into impromptu chats in the boss' office.

Michael Hampton

@Adrian You're trying reverse psychology on them?

Adrian

@MichaelHampton Moving our 300 workstations to Windows. Honestly, for what our staff need and their LOW level of tech savvy, I have no justification in continuing to inflict Linux on the Desktop on them.

pauska

@ewwhite nah, I'll probably just use ARC.. 99% of writes are going to be sequential

or well, ARC/L2ARC

Michael Hampton

12:22 AM

@Adrian I hope you plan to leave before that happens.

Zoredache

@Adrian Has he come up with the budget to upgrade the hardware, and buy lots of licenses?

Adrian

@MichaelHampton I hope to leave before Christmas.

Michael Hampton

@Zoredache That's my fault... I accidentally mentioned a site where Microsoft donates software to non-profits...

Adrian

@Zoredache Licenses for everything but Office will be easy, the hardware will be interesting. But he'll likely still pull it off under $250/seat with maxed-out 2nd-hand Dell GX520s.

@MichaelHampton We've known about TechSoup for years. We buy stuff from them all the time for our client networks that are all Windows XP.

"Buy", of course. It's mostly to cover shipping.

So it's pretty much 2013 or 2014 that it'll happen. I certainly plan to be gone before then.

Michael Hampton

I hope they're not deploying... XP!

Zoredache

12:27 AM

go Windows 8 :) Since you are changing to a different UI, you might as well go straight to the new UI

Adrian

@MichaelHampton Probably not. The new padawan knows 7 pretty well.

Shane Madden

That'd be awesome - deploy Windows XP about a month before it's end of life.

Adrian

My assistant can handle Windows Server. I'm the one that isn't a good fit anymore.

@Zoredache They might. I'm not sure I really care enough to even provide a recommendation.

Michael Hampton

Gawd, I don't think I'd inflict Windows 8 on anybody.

Journeyman Geek

lol

Peter Grace

12:32 AM

hah

Baby steps, guys. I have to actually teach the whole team IPv6 first before they'll let us spin it up.

Journeyman Geek

@Adrian: maxed out how?

Michael Hampton

I have lost count of how many times daily I manage to hit the right Win key and have Metro pop up right on top of what I was doing.

Journeyman Geek

lol

Mark Henderson

@PeterGrace Are you going to have the same problem everyone has where your IP addresses are stored as either char(15) or int?

Shane Madden

I haven't even touched the desktop version, just server 2012.. but yeah what a bad UI.

Journeyman Geek

12:33 AM

@MichaelHampton: been forcing myself to use windows 8 for the contest on SU. I think I can live with it.

Michael Hampton

@PeterGrace You mean teach the sysadmins, right?

Journeyman Geek

will probably end up installing a proper start button replacement tho

Shane Madden

That few-pixel-wide corner where the start menu fires is not fun to hit when it's a VM in a window.

Peter Grace

@MichaelHampton Right. We're getting to be a big team.

Michael Hampton

Just checked my MySQL database schema, to be sure...
`ip` TEXT NOT NULL,

Mark Henderson

12:36 AM

@PeterGrace Hows the hiring process? I saw the ad go up a while ago but radio silence since ;)

Michael Hampton

I saw the ad too. If it weren't so much a Windows shop I'd be all over it.

Peter Grace

We've filled the position

Mark Henderson

@PeterGrace So when do we get to meet them?

ewwhite

I think @peter didn't want to tell everyone that I was hired.

Peter Grace

@ewwhite haha, why didn't you interview again?

ewwhite

12:37 AM

@PeterGrace Kyle didn't think I was good enough :)

Peter Grace

oh pishposh

ewwhite

I failed the interview.

Mark Henderson

@ewwhite Well i didn't get a chance to interview at SE, but I failed an interview at FC, so welcome to the club :)

Peter Grace

Anyways, we have filled the position, and it is a pretty big name in the windows community and I'm not sure if I'm allowed to disclose it just yet since I think he's still notifying people.

Journeyman Geek

@ShaneMadden: I gave up running windows 8 as a VM, threw it on spare system, VHD install since its disposable.

Peter Grace

12:39 AM

Once we get the all clear, I'll spill the beans.

Journeyman Geek

Works fine other than boot time

Shane Madden

@PeterGrace Windows community here, or elsewhere?

Mark Henderson

@PeterGrace Is his name Gates... Bill Gates?

Journeyman Geek

windows 8 is not a great vm guest.

Zoredache

Evan?

Shane Madden

12:40 AM

@JourneymanGeek Yeah.. I need to support it in VMs. Works decent on a new enough ESXi.

Journeyman Geek

@Zoredache: thats one of the few things that might make me ponder leaving SU/SF ;p

Michael Hampton

Now if you guys ever need a Linux person....

Journeyman Geek

@ShaneMadden: might be less painful when you learn the shortcuts. Win-C does the same as 'hover, not click on the hotspot that we have hidden somewhere'

Peter Grace

@ShaneMadden Elsewhere.

@MarkHenderson Nope.

@Zoredache Nope. :)

Zoredache

@JourneymanGeek Did you think I was talking about Evan Carrol? I was was talking about Evan Anderson, the guy with the most Windows upvotes. serverfault.com/users/7200/evan-anderson

Shane Madden

12:42 AM

@PeterGrace Gotcha. Interesting!

@JourneymanGeek For a VM console, that's even worse ;)

Michael Hampton

Wait until you run VMware full screen, AND you have virtual desktops on your Win 8 host which switch when you move the mouse to a screen edge. It becomes impossible.

Shane Madden

Ugh.

Michael Hampton

After living with this for a few weeks, I am utterly convinced that either Microsoft skipped UX testing on Windows 8, or completely ignored the results.

Peter Grace

@ShaneMadden Well, that's not entirely accurate. He participates mainly on StackOverflow, not so much serverfault or comms room, specifically. But he is a member of the stack community at large.

Michael Hampton

Is there anyone left who isn't on Stack Overflow?

Mark Henderson

12:49 AM

@PeterGrace Well I look forward to finding out who it is

Especially as how they TOOK MAH JOB

ewwhite

ouch

Mark Henderson

@MichaelHampton I have about 100 rep there cos I spent it all on a bounty

Peter Grace

heh

Michael Hampton

Heh, I still collect the occasional 10 rep on SO from answering a question about PayPal's API and a really obscure OpenSSL question.

Shane Madden

@PeterGrace Also interesting. So I should start digging around in the powershell tag on SO to find out who it is, then? ;)

Journeyman Geek

12:52 AM

@Zoredache oh, him ;p. Then its fine

@MichaelHampton: I'm convinced they let the designers run wild

Michael Hampton

I have 1,103 rep on SO. WTF?

Journeyman Geek

have you seen the DX 11.1 changelist?

Peter Grace

@ShaneMadden ;)

Journeyman Geek

most addons seem to do with faster 2d rendering and text. tho tesselation seems juicy

Michael Hampton

So my gf is getting her master's in accounting. The other day I saw a textbook titled "Accounting Information Systems" on the kitchen table. I flipped it open at random and saw screenshots of Microsoft Access. This is apparently, according to the textbook, an enterprise database.

Journeyman Geek

12:58 AM

lol

Peter Grace

Nice.

Journeyman Geek

@MichaelHampton: according to some, excel is too

Peter Grace

Well, accountants don't generally require databases on the same level that we do

Michael Hampton

Yeah. We're going to be having a long talk about that eventually. Fortunately she'd bought the wrong textbooks and they were being sent back.

Peter Grace

access "works" for them

Journeyman Geek

12:59 AM

(hell, while we did a ms-sql investigation, the other assignment we had for forensics analysis involved spreadhseets)

not to mention, most end users probably won't see anything past a frontend.

HopelessN00b

@MarkHenderson No, just 30Mb/5Mb Cable. No FIOS servcies in this crappy state. Though, as of 2004, they'll start rolling it out any time now.

Zoredache

@MichaelHampton So what off-the-shelf RDBMS would you suggest for an accountant?

Shane Madden

I'd recommend sqlite over Access. But then I've had to support web applications with Access backends. shudder

Michael Hampton

@Zoredache I could suggest many things, but they'd never actually spend the money on them. Guess they're stuck with Access.

HopelessN00b

@Zoredache For an accountant? I've got a claymore mine I could take off my shelf for that usage, as long as you promise to make sure you point the front at the accountant.

Zoredache

1:10 AM

Or better yet, can you point at a simple RDBMS you can point to an end users so that can mess around enough so they understand database design enough to realize they are not smart enough to build databases.

Journeyman Geek

lol

@Zoredache: from what i've seen of databases, I'd think i'd rather leave designing them to someone who actually specialises in them

Michael Hampton

So why does the system wait until there are 6 posts with flags before it bothers to put up the notification?

HopelessN00b

And speaking of dipshits who shouldn't have jobs or be allowed near a database, does anyone know what the deal is with "password must be between 8 and 12 characters and not contain special characters?"

I mean, just a database field, so... fut the whuck?

Zoredache

@JourneymanGeek I certainly agree, but end-users don't think that. I think Microsoft built access so bad specifically to make people realize that they should hire a developer.

Shane Madden

@HopelessN00b It better be stored as a hash, not the actual password.

mgorven

1:13 AM

@HopelessN00b Because the password isn't hashed, not escaped/quoted in the application, and someone defined the column as TEXT(12).

Michael Hampton

Which also means that a SQL injection on the username or another field is likely to succeed...

Shane Madden

I can understand not allowing some of the stranger characters like newlines that might screw things up. But most anything else should be fair game.

Michael Hampton

@HopelessN00b Is a claymore mine cheaper than an Access license? If so, I might actually manage to get the beancounters to approve it before they realize what's going on...

2

Mark Henderson

@HopelessN00b Because in some non-SQL databases the * letter acts a wildcard nomatter where

I once had to maintain an app on a btree database that had no notion of sql escaping (because it wasn't SQL), and if you entered a password of "*" it would match all fields

My (old) bank forced me to use a password that was exactly 5 characters once

I encountered one! My first computer was a Soviet Iskra EVM (basically an IBM PC/XT with the Iron Curtain's own bus, but fully software compatible). On some rare instances it was freezing, sometimes producing garbage on the screen. Upon closer investigation I discovered: The system had a Sieme...

Cool story bro, but it really isn't relevant to the question.

HopelessN00b

1:20 AM

@mgorven Great. The first explanation for that BS that actual makes sense and makes my asshole pucker so hard it hurts.

@MichaelHampton Like I said, free provided you make the accountant use it with the right end pointed at him. Have him invite the whole department to watch over his shoulder too, for bonus points.

Shane Madden

@HopelessN00b This is why I use a different random password for every login everywhere. Because people do dumb things.

Michael Hampton

@HopelessN00b Yes, but I was hoping to have the company pay for the claymore...

HopelessN00b

@ShaneMadden Me too, but still a password like that protecting my internet account? Ouch. On the other hand, the username field could be up to 32 characters. :/

Michael Hampton

@HopelessN00b You might need all 32 characters for the SQL injection.

Shane Madden

@MichaelHampton Never hits the table if properly escaped!

Poor little Bobby Tables.

Mark Henderson

1:25 AM

@PeterGrace - Your RSS feed is feeding up some vomit

It regurgitated an old blog post from 2010

Blog - Stack Exchange: Stack Overflow API Private Beta Starts

Jeff Atwood on March 31, 2010

If there’s some kind of award for longest running user request, it has to be this one:

When will you guys have an API?

One of our new year goals for 2010 is to build and release a great API — for all the trilogy sites.

Over the last month, API work has been our highest priority. Now we’re finally ready for private beta. We realize that getting an API right is challenging, and we would like “friends of the Trilogy” to begin giving us input on how our API should look and function. …

Michael Hampton

Where in hell are all these home server questions coming from?

Peter Grace

@MarkHenderson Yeah, we noticed it earlier today, the appropriate people were notified I think.

@MarkHenderson Here's another one you can burninate.

Q: Default Centos Linux password for root account

I installed Centos 5 OS and didn't setup any user password at that point but when boot up machine its looking for a username & password. default username is root I am sure doesa anyone knows default password for it.

linux centos password

Michael Hampton

NARQ

Shane Madden

30k views, really?

Michael Hampton

You can't proceed through the installation without choosing a root password and typing it twice. So he's missing critical information there (e.g. somebody else installed it, he used someone's kickstart template, etc.).

Mark Henderson

@HopelessN00b Just... be careful. 30kviews means its bringing a lot of traffic to the site

Michael Hampton

1:50 AM

30K views over 3 years is... ~ 29 views/day

I wouldn't delete it, but it really isn't definitely answerable in its current form, and the user's probably never coming back to clarify it.

Adrian

@JourneymanGeek Maxed out in terms of RAM. I think they'll do 4GB max, which should be enough for Win7.

Mark Henderson

@MichaelHampton Im considerign nuking the +8 answer from that question because it doesn't answer it, and there are better answers down below

The guy has never been to the site before

So he won't miss the rep

Adrian

@MarkHenderson I'd support that. Also VTC'd it.

Michael Hampton

Ehhh... Maybe it was worth +8 then but I wouldn't upvote it now. And all of the answers are just wild guesses.

Shane Madden

8

A: Default Centos Linux password for root account

I'm pretty sure that the normal install process requires you to type in a root password. There is no 'default'. Since you can't login at all, you haven't customized the machine yet or populated it with data, maybe you should try the install process again and look for the screen that is promptin...

A: Default Centos Linux password for root account

Some default root passwords I've encountered in the past: "root" "toor" "" (no password) Googling CentOS root password gets me this, which has the LiveCD password as "12qwaszx". If you installed using the LiveCD, then that may be it. Edit 2: the editing - Finally, this document on CentOS 5 ...

Shane Madden

@MarkHenderson I just pushed it up there. :)

Michael Hampton

The +5 link-only answer can probably go; the +4 answer right below it actually explains the process.

Though, overall I'm sticking with NARQ

Mark Henderson

IU like the answer about kickstart; although I dobut that's this guys problem

Adrian

If the guy's still having the problem, he's beyond hope anyway. =)

Are Proxmox questions actually on topic? I've never heard of anyone using that in production.

Michael Hampton

I usually consider those "too localized".

Journeyman Geek

2:04 AM

@Adrian been running it on 1 and 2, which seems ok. I do use beefier processors tho, not celeries

Adrian

@JourneymanGeek I have a hard time considering anything running a Celeron to be production.

Journeyman Geek

no scratch that, i've run it on a 1.6 ghz atom, with 2 gigs of ram

Michael Hampton

We wouldn't use something like Proxmox but low-end hosting providers and end users who don't know any better use such things. Sometimes they find their way here since it's a "server".

Journeyman Geek

@Adrian: I'm a little too familiar with the concept of 'working with what I got'

Adrian

@JourneymanGeek Dude, I know that well. I work for a homeless shelter. But there's limits.

Journeyman Geek

2:06 AM

;p

@Adrian: we're still were still running PIV 1.6es until this year.

HopelessN00b

@MarkHenderson Alright, now it's just run-of-the-mill crap and not heinous crap, with all that pruning complete.

Michael Hampton

Yeah, and it got 4 close votes.

On second thought, Proxmox looks like it's shaping up to be a nice little product. Still rather niche though.

@Adrian Careful playing around with mangle; you'll usually end up mangling a vital organ.

Adrian

Michael Hampton

You have really good health insurance, right?

ewwhite

WHat is mangle?

Adrian

QoS and packet modification

Michael Hampton

2:38 AM

@ewwhite It's a whole set of iptables possibilities for rewriting pretty much anything in a packet.

And it scares me.

Adrian

Oddly, I usually only fiddle with that when I've been drinking a little. It's got some really cool features.

Mark Henderson

@Adrian I'm fiddling right now

@MichaelHampton Uhhhhhhhh

What image?

Michael Hampton

@MarkHenderson I think you're still asleep and dreaming. Go have some coffee and wake up.

ewwhite

probably

Adrian

Watching the cat pester the GF while she tries to do Yoga in the living room. Who needs television?

Mark Henderson

@Adrian GF doing yoga in living room == all the entertainment anyone needs

Michael Hampton

My first thought is... you don't do this on AWS.

ewwhite

@MichaelHampton yoga? Or scalable ZFS-based storage?

Michael Hampton

Either.

Adrian

2:57 AM

Cat's all pissed off because someone's on the floor and not there to pet him.

Mark Henderson

@Adrian Now the question is, which pussy do you stroke?

Adrian

Heh. =D

Mark Henderson

So does anyone ever bother with defragging any disks any more?

Michael Hampton

Did they ever?

Mark Henderson

@MichaelHampton I used to defrag slow drives, like laptops, once a week

I dont think I've defragged anything since about 2002

Michael Hampton

3:02 AM

I had a friend's XP laptop in here for general cleanup a couple of weeks ago, and defrag took two days.

(My friends get a discount rate, but they DO pay...)

Mark Henderson

@MichaelHampton Shiiiittteeee

Jeff Ferland

@MarkHenderson Once in a while. My Mac managed to fragment a bunch of 8MB image files. That was worth the time to delete & restore them all.

Michael Hampton

On the bright side, it was malware free.

Adrian

@MarkHenderson My padawan spends quite a bit of time defragging XP workstations and running registry cleaners.

On the bright side,i soon hope to make that someone else's problem.

Even thinking about going for a Microsoft position if the pile of cash is big enough.

Mark Henderson

@Adrian I thought you guys were an Ubuntu shop?

Adrian

3:09 AM

@MarkHenderson 95% Ubuntu. But soon not to be.

Mark Henderson

@Adrian Ohh, big move?

Michael Hampton

He used some clever reverse psychology to convince his boss to switch to Windows.

Adrian

Boss is planning a 12-month migration to Win7 starting whenever he gets the budget.

Michael Hampton

.....That'll probably be sometime after Windows 14 comes out.

Adrian

@MichaelHampton Yeah, so I'm coasting there. I quite literally don't give a shit whether they decide to go with XP since they have XP licenses for all their workstations.

If I had the cash, I'd have given notice today.

Mark Henderson

Or accidental.

I spy with my little eye... an RFC1918 address as hop #1!

gparent

typical of hosting providers

Michael Hampton

I'd expect something like that to be very well documented.

gparent

3:44 AM

Well, my hosting isn't exactly premiere, but do you think that would really affect anything? Every other site on the internet seems to handle it fine, as well as the entire routing path until SE's router.

Michael Hampton

Bah, I am sure it breaks SOMETHING, like any use of NAT.

gparent

well if it's one to one nat.

don't think it would change much

ipsec maybe

Michael Hampton

Sure, 1-to-1 NAT is fine. Again, as long as it's well documented.

gparent

What is there to document though, I don't understand

Michael Hampton

Gawd, I can't wait for IPv6.

The fact that it's in use, to start with.

gparent

3:48 AM

is one to one nat not common for VPS providers?

Michael Hampton

No, it's highly unusual at the low end.

gparent

I don't know how these guys do their networking, perhaps I could ask for some information

Michael Hampton

So on your VPS, if you run ifconfig do you see YOUR IP address or an RFC1918 address?

gparent

I see my IP.

Michael Hampton

Oh, so it isn't 1:1 NAT at all. They're just using RFC1918 on their router links. That's a whole other class of weird.

gparent

and you can ping my VPS directly, and I can host services on any port

Well I'd think it'd be common for WAN

but I'm not really experienced in that sort of things, going by what I know and extrapolating.

Michael Hampton

Quoting from a nice Cisco guide:

Or I would if it would let me copy the text, which it won't. Fucking PDF.

Anyway, the gist is if you put RFC1918 addresses on a (public) router link, certain ICMP messages break, and certain TCP connections break.

So, yes, your host has done something incredibly stupid.

gparent

I'll ask around

Hm yeah, good point

reading that document now

Michael Hampton

It's at the bottom of page 4/13

gparent

I thought the (ip) clarified it

Adrian

Hmm. OT? Not OT?

Q: (include_path='.:/usr/share/pear:/usr/share/php') in Unknown on line 0

I'm trying to setup zabbix on a right-installed CentOS 6.3 server. Apache and php have been installed. The test page with phpinfo is working fine. However, when I try to access the zabbix frontend setup pages, I get the following error message in error_log PHP Fatal error: Unknown: Failed o...

php centos pear zabbix

Appears to be annoyingly code-focused, but probably needs a rewrite.

@gparent OK, I'm posting this as an answer.

gparent

SE isn't replying to me as of yesterday because path MTU discovery is broken?

Michael Hampton

There's more than one way to copy text from a PDF.

That's what it looks like. And it's broken because your host's network is run by an idiot.

gparent

I asked for some info on their networking on a forum I visit until I get a reply from team@stackoverflow

Michael Hampton

Copy and paste successful!

@gparent I know a great place to ask a question like that. It's called Server Fault...if you can ever get there.

Adrian

@MichaelHampton Blocking ICMP again?

My boss used to like to do that. Didn't understand why MTU Discovery didn't work.

gparent

4:07 AM

@MichaelHampton Except I meant their networking, not a networking question :)

Michael Hampton

@Adrian These particular idiots used RFC1918 addresses on a public (OUTSIDE the bloody NAT) router.

Where there isn't supposed to be any NAT in the first place.

Adrian

@MichaelHampton Ok. That's pretty damn stupid.

A: Cannot contact serverfault.com

This looks like a problem with the network where your servers are hosted. They have used RFC 1918 addresses on their router on a public network, a huge no-no. 1 172.18.13.130 (172.18.13.130) 0.026 ms 0.013 ms 0.011 ms Among other things, this causes Path MTU discovery to break, which me...

Have you deployed IPv6 yet? I'm getting sick of this NAT shit.

gparent

it's in various states of deployment

Adrian

No, they didn't get rid of the 20 review limit. I got cut off again.

I wonder if the 20 limit goes up with rep.

Honestly, there's so much bullshit with changing stuff around all the time that I it drastically reduces me interest in pushing my rep up.

Michael Hampton

4:14 AM

@Adrian I can review maybe 35-40 items before I get cut off. But I never get to, since I RUN OUT OF CLOSE VOTES on the NEW shit that gets posted.

Adrian

Screw it. All the dicking around is annoying.

Michael Hampton

@gparent Just out of curiosity, what's your default gateway set to?

gparent

it's a p-t-p openvz thing

I can't tell

Michael Hampton

Can you move off of that POS before the next monthly bill?

gparent

not if the only thing it can't do is reach serverfault.com no

Michael Hampton

4:20 AM

Oh, trust me, this isn't the FIRST or ONLY problem you'll have. I presume you're using it as a proxy or VPN or something?

gparent

Between what you mentioned, only as SSH tunnel.

Michael Hampton

Gawd. And I thought I'd seen all the possible ways somebody could fuck up an OpenVZ installation.

gparent

IPs sure make you mad

Michael Hampton

Doing it wrong, whatever it is, makes me mad.

Which is why I don't work in the corporate world anymore.

Anyway... I recommend you go hit up lowendbox.com sometime, and pick anything that isn't OpenVZ. I have yet to see a single OpenVZ installation that wasn't horribly overcommitted, misconfigured, completely unusable...

A: Sudoers file permissions

Put your code in a script (you ARE writing a script, right?) and grant the user sudo access to the script. And, I hope you have good backups.

Journeyman Geek

ugh.

So, I have a gig with a local company... apparently helping them draft bid proposals

Michael Hampton

And the problem is...

Journeyman Geek

and basically I got an e mail saying 'We have a meeting with XXX, Tech Director - to introduce you; and we can get things moving. 1pm at YYY' I got the e mail at 12.11

I don't know if I need to be there or not.

Michael Hampton

Might be a good idea. Better eat something first, though.

Journeyman Geek

done, and the laundry, need to leave the dog home alone tho

Jeff Ferland

5:29 AM

@MichaelHampton How the hell did 3 different people write about putting destination filename as the target of the sudoers config line??

Michael Hampton

@JeffFerland Because developers.

And, you forgot to advise the guy to make backups. Whatever he's trying to script, I'm quite sure it's going to end in data loss.

Jeff Ferland

@MichaelHampton a) you already did. b) we're professionals! :D

Michael Hampton

Eh, I'll give fair warning, even to a developer.

Jeff Ferland

@MichaelHampton I was nice enough to give fair warning last night when I reserved a cluster for testing. Letting resources like that timeout on the calendar without realizing it is dangerous.

Michael Hampton

Oh, I just gave up and wrote his script for him...

Journeyman Geek

5:40 AM

Oh. Mon before class.
Oops. And this is why I need work experience.

Michael Hampton

So that you can figure out which day a meeting is when it isn't specified in the email?

Journeyman Geek

lol. so I know not to bother turning up for a meeting that may be in 50 minutes, and not in the same building I'm in

Michael Hampton

@JeffFerland I hope he likes my variable name.
