@Magellan: its midnight ;p
@LucasKauffman I did find the machine chundered a bit when running more than two machines - but the models I have have dual 1.5Ghz and 250GB HDDs.
@JourneymanGeek Sydney time.
ahh, damned future people ;p

@JennyD Hehe
"limited time discount" - "offer started 06-19-2012" - and I just verified the code is valid. Hard. De. Har.
16:01
soon as we hire another aussie and train them up, I can go back to a reasonable noon to 8 local time.
@Dan Seriously, of course I can get upset and pissed off, and most especially by people that I care about in some way. But I don't keep grudges; I may step away to cool down but I wouldn't just disappear forever because someone upset me.
@TheCleaner Compaq is dead to me. It was all over when "BBS Download Service" stopped answering my phone calls.

@JennyD That's okay then - the room was definitely missing you
RIght, I'm off to go have my arse kicked some more by c#
Is @pauska around?
I have an RDS question
Hm. What kind of RDS question?
16:05
I have a customer using UAG to publish VDI desktops
But they get the "This remote connection could harm your local or remote computer" prompt
The broker and the UAG portal are both using wildcards trusted by GeoTrust so the certs are good
just not sure why they're being prompted for that

So, one of my coworkers has left, and we're currently looking for someone to take over as the primary Linux admin on the team. There are currently three of us, including David Blank-Edelman, who you might know as the author of a few Perl and SysAdmin books. Here's the job posting. Submit a resume and […]

@Skyhawk LOL
@StackExchange ooooh
This guy sure wants to do EVERYTHING from his installer. (note previous question as well)

Q: deny local logon for a new user through command line windows server 2008

diceI am creating a local user account that I want to be able to connect over ftp, but not log on to the server, I believe the way to do this is to deny local logon but am unsure how to achieve this via the command line. This needs to run from an installer on windows server 2008 hence the command li...

Ars Technica's review of the 2013 Mac Pro. "Price as reviewed: $6,499" hnng
Yeah, but it ain't working for them...it's with him at his University.
So I'm assuming sucky pay? I say that because I did a year contract at a local university and made about 20k less than the average sysadmin was making at a private company. They touted the retirement system and tuition allowances, but I still thought the pay was pretty lousy.
@TheCleaner yeah, that's why I walked away from that job offer I received 3 weeks ago.
@TheCleaner Oh, okay. I'll go work at StackExchange then...

@ewwhite Really?
@ewwhite its OK everything you need to know you can scrape off SF :-)
@ewwhite Sure but then you'd never come back to SF, except to post in Meta once a year about how you guys still like us and then go back to SO.
heh, yeah.
Bart, what?!?

A: deny local logon for a new user through command line windows server 2008

Greg DrakeThe answer in this thread isn't exact, however it should start you on your way. In a nutshell, you just want to use the command line to modify the registry value of the Deny Logon Locally (or Interactive Remote or both).

Bart who?
16:21
Hopefully that guy doesn't go all "SnakeDoc" on us now.
@ewwhite o.O
@tombull89 It burned a little.
@ewwhite Not enough Windows?
@Tanner I was asked a bunch of BS trivia questions, and bristled at it
I've been repeatedly sending the lyrics from Eric Carmen's "All By Myself" to syslog for the past couple days. Nobody has noticed.
16:27
@TomO'Connor d'aww.
The scheduler and I have been chatting, and we've decided that web requests are the last thing we feel like doing right now
The server quits.
@ewwhite they're a windows shop. I always find those places to be suspect.
I want to write a bot now that'll randomly squirt song lyrics to random IP addresses, hoping to find an unfiltered UDP:514 syslog out there somewhere.
@Magellan Nah, Kyle told me I wasn't good enough.

shit's on fire yo
16:28
So I took the job at Logicworks instead.
@ewwhite Heh. That why he doesn't hang here anymore.
He said something about me "going back and learning fundamentals..."
@ewwhite Cute. More confirmation of my impression that it's a company populated primarily by assholes.
I think I was asked the, "what happens when you type www dot blah in your browser and hit Enter?" question.
@ewwhite standard fare in every interview I've ever done.
16:33
I think I replied with, "suck my ASS!!!"
@ewwhite "Gee, nothing?"
@ewwhite That's a schoolbook question, not a sysadmin question...
lol, the Danish Prime Minister yesterday afternoon:
@JennyD Right, over time, I've grown impatient with questions like that...
@ewwhite If they are interviewing people for entry-level - then yes, it might be valid. Someone with your experience? It's insulting.
16:34
I used to have a a crib-sheet of things I'd encounter in every Linux/finance interview...
hard-links/soft-links/Nagle's algorithm/CPU schedulers/rtctl/cset/taskset/common sysctl settings.
what to do if a filesystem fills up with a runaway logging application...
@ewwhite shoot the programmer? No wait, that's wrong.
Set programmer on fire as warning to others.
@JennyD Naw. Log trucks. Lots of them.
@JennyD I so wish that were the case.
16:39
@Magellan Is DevOps still the way of the World?
@ewwhite of course it is. My Dev are too clueless to even figure out DevOps though.
really.
@Magellan I've heard a lot less of devops speak recently
each of them has their own personal server hardware. and if it deploys on their own personal hardware, it's good enough to ship.
And my group gets to deal with figuring out how to do 1500 deployments.
@ewwhite Not if this is to be believed: dave.cheney.net/2014/01/23/what-did-devops-mean
and then they whine that we're 5 builds behind and throw hissy fits to avoid issuing hotfixes.
16:42
@TomO'Connor I hated the word.
I dunno. It got me some very lucrative jobs.
@TomO'Connor how lucrative is lucrative?
@TomO'Connor That article does make sense. But the word has buzz so it's not going to die...
@ewwhite The best paid one (which ironically was the least enjoyable) was about 100K USD equiv.
give or take
@TomO'Connor See, a good DevOp (singular) in Chicago or New York can get $150k-$200k.
16:44
@ewwhite finance?
mainly because the finance companies are starting to embrace DevOps (automation) in that sense.
I refuse to work in finance.
btw - this customer has a standard wildcard cert from a trusted CA that they feed into openssl and export "new" certificates from, except they're all untrusted. And they install them everywhere. wtf
but then the startups are trying to get the same talent pool....
I turned down a job with a payday loans company which would've probably been closer to 150k
16:46
@MDMarra So they sign new certs with a non-signing certificates and then wonder why they don't validte?
because of their ethics.
or lack of.
@MikeyB yes
@TomO'Connor you're a sysadmin. Ethics don't matter :P
@TomO'Connor heh, I did the same... plus they used Debian.
@MDMarra Cause it's SO HARD to just make your own CA and make your devices trust it.
16:47
Oh, they totally do.
These are the folk who lend money to people with no credit rating, then the interest goes up daily, so the APR is like 5600%
it's just wrong
Usury...
Payday loans in the United Kingdom are typically loans of up to £500 to be repaid over a short term, or until "payday". In the absence of restrictions on interest rates the typical annual percentage rate (APR) for payday loans can be 1,000 percent APR or more. A typical payday loan in the United Kingdom costs as much as £25 for every £100 borrowed per month The Payday loan industry in the United Kingdom has grown rapidly, with four times as many people using such loans in 2009 compared to 2006. In 2009 1.2 million people took out 4.1 million loans, with total lending amounting to £1.2 b...
I almost thought @MDMarra would jump on this one with a fiendish rub of the hands and thoughts of rep gold. But I don't know...it seems like a good answer would be a book. I considered adding a few options for each but even then my head started swimming with alternatives and rabbit trails.

Q: What are some good reasons to create a new forest, child-domain, tree, site, OU in Active Directory?

tr3quart1staWhen is it worth it to create one of the above and when is it better to keep things in the same place?

@TheCleaner goddamn it. There goes my lunch break
@ewwhite Usury laws even in the US aren't necessarily that good
e.g. "H&R Block's Rapid Refund" that can wind up costing you more than your refund
16:52
Linux people... thoughts on this?
Stupid question... how do I do this properly:
XFS (zd16p1): Filesystem has duplicate UUID a22fbb0d-b6ad-48a7-9a86-56276d19230c - can't mount
@ewwhite You are using multipath?
@MikeyB naw, trying to take advantage of ZFS zvol snapshots of XFS volumes for a tape backup.
@ewwhite Trying to mount via uuid or devname?
16:53
dev name...
there's a duplicate UUID
mounting with nouuid
@ewwhite Oh.. I was going to say try '-o nouuid'
burn...
[root@OGC_Mirror ~]# mount -t xfs -o nouuid  /dev/zd16p1 /pprobackup
mount: block device /dev/zd16p1 is write-protected, mounting read-only
mount: cannot mount block device /dev/zd16p1 read-only
Got it...
mount -t xfs -o nouuid,norecovery  /dev/zd16p1 /pprobackup
@MDMarra I retracted my close vote. Have at it...should make for a canonical possibility on AD design if it rocks.
@MDMarra it's a warning from activating resource mappings
(local printer, local disks etc)
@pauska We have those disabled per UAG policy
16:58
If it's published through UAG then it should be signed..
@MDMarra so no redirection at all? not even clipboard?
@pauska none
no clipboard, printers, or drives
the UAG policy is set to "never" for those three
@MDMarra - whoa...the OP deleted the question...maybe you should create a question AND the answer if you still want to go down that path?
Also, who the fuck deleted that question
Can a mod undelete it?
OP
but yes, i've undeleted it.
Stupid OP.
Hey...I'll be happy to create a new one with a better question scope if it means free rep... :)

Was it a stupid question ?

Q: Workstations in remote site don't know about new AD realm

MikeyBI've recently migrated a classical Windows Domain (samba3) to an Active Directory domain (samba4). Workstations in remote sites do not have a local DC so they are not aware of the transition, hence they do not automatically migrate to the Active Directory setup and I have to join them manually. ...

@Iain Not really.
Hey! Look! A question.
@pauska what should be signed?
It really borders over to the "book answer" @Iain -- but since Mark doesn't mind spending the time to write the book answer, I retracted my close vote.
17:01
@MDMarra the RDP file that the client gets
try exporting the RDP instead and launch it
and try to edit it.. it should be encrypted
Its just using the pre-defined RDP application in UAG
@pauska "encrypted"
@MikeyB well.. yeah
@MikeyB I thought you were deploying 7,000 RODCs?
3
@pauska How do I do that - never used UAG
17:04
@TheCleaner 28000!
@MDMarra I can't remember to be honest, been years since I've touched it
ah ok
@MikeyB well, now that's just silly.
@TheCleaner done
@pauska do I have to add the UAG portal's certificate's thumbprint to the trusted RDP shit?
@MDMarra Same as everything else, make sure the clients trust the root CA
17:09
Yeah, they do. It's signed by GeoTrust (Equifax)
But I'm seeing some things about needing to configure the thumbprint in RDS policies
but I dont know how that factors in with UAG
there are so many moving parts to this that I've never worked with, I'm half tempted to just have them open a ticket
That blog post ^ contains a walkthrough of creating a GPO with a specifically trusted thumbprint for rdp
@MathiasR.Jessen How does that factor in with UAG and non-domain computers
UAG is actually publishing the RDS session
So does the GPO need to apply to the UAG server...or
@MDMarra That would only apply to domain joined computers
Are you trying to build some sort of FFA portal?
17:13
FFA?
Home time. I will be back at some point, not tomorrow though. waves
@JennyD lata
missed ya
@MathiasR.Jessen instead of VPN to get a VDI desktop, they go to the UAG portal, launch the published RDP application to connect to the VDI farm, then they get a VDI session
They were going to use RDWebAccess and a RD Gateway at first, but decided on publishing through UAG instead
An the VDI farm is behind UAG as well?
yes
So they have a gateway/webaccess box that isnt really being used, and are basically connecting straight from the RDP application published in UAG to the VDI farm
the subnets of the VDI desktops and the broker, etc are all trusted in UAG
And they can connect
But they get the warning I mentioned when connecting
If they click "Continue" they're prompted for creds a second time even though UAG us configured for SSO, and then they connect
17:17
@MDMarra Interesting ... I've only done RD publishing though UAG with wildcard certs
@MDMarra More concise then I would have expected. Nice job.
@MathiasR.Jessen This is with a WC actually
Oh @MDMarra - there's also this article you can use to help your post too.
Well there's a wildcard on the broker, etc, but the portal itself has a single name cert from the same CA
"Active Directory offers five basic containers: forest, tree, domain, site and OU. These containers, used to segment and organize a network, were designed with specific uses and restrictions in mind. Thus, it is important to understand these restrictions when planning out your AD-based network.

Forests are used to create a structure with administrative independence and autonomy from any other forest. Each forest has its own unique schema. In most cases, a single organization should have a single forest. The reasons for multiple forests include merger or acquisition of an existing IT depart
from there ^ ... I didn't feel like quoting the whole article and editing your answer, and didn't want it to be a separate answer from yours.
17:27
@MDMarra The clients are all Win7? Sounds a bit like this issue
@MathiasR.Jessen It's exactly that issue
I only want some key points, didn't expect long answers. — tr3quart1sta 34 mins ago
But thats literally the only thing I've found that mirrors this situation so I dont know if I trust it haha
boy, you came to the wrong neighborhood.
@MathiasR.Jessen But yeah they have UAG 2010, 2012 R2 Hyper-V clusters and 2012 R2 VMM, 2012 R2 RDSHs, and Windows 7 VDI guests
I may just tell them to open a case with Microsoft
:(
Too many things outside of my area of expertise, and I'm just racking up billable hours guessing at this point
17:29
@MDMarra Make dat money!
ha
I get paid the same
(and feed me Cheesesteaks next visit)
gross
Next time, we'll go to Baby Blue's BBQ. They have great pork there
@MDMarra Hmm, I do need a daily helping of cow, chicken and pig.
yarr whitespace will be the death of me
17:33
@ewwhite They have a dish there that has pulled pork, a smoked sausage, and brisket with corn bread and a side of your choice (I get mashed sweet potatoes)
You basically die after eating it
@MDMarra Hmm
@ewwhite First you take the chicken, and wrap it n a pig. then you take the pig and wrap it in a cow. Then you take the cow and you slather it in mashed potatoes. Then you deep fry the whole thing.

...now I want that :(
potcowporken!
Just running a SCSI tape backup of a snapshotted XFS filesystem on top of a compressed ZFS block volume running on an HP ProLiant Smart Array RAID 1+0 logical drive comprised of SATA disks... NBD.
The weird benefit of this is that the tape backups run 300% faster...
But is 300% 3x as fast or 4x as fast? :)

user2683Suppose John has 5 sweets. Is there any difference between the following two sentences? Jack has 3 times as many sweets as John. Jack has 3 times more sweets than John. I prefer the first construction and would know unambiguously that Jack has 15 sweets in this case. However in the sec...

@PatoSáinz Eterm

@voretaq7 Gonna need a bigger deep fryer...
@Tanner we're going to use the eerie canal locks.
the goal is to eventually get the meal wrapped in a mink whale :)
@voretaq7 You like security, right?
Also why is my development environment being an angry bitch?!
@ewwhite security is inconvenient :(
@voretaq7 the software vendor I deal with is pushing a solution that provides direct access to their Linux server shell/console via code.google.com/p/shellinabox
"It's okay.. it's secure... we're using SSL"
except it's a web browser link right to the shell of a production server.
@ewwhite Shell In A Box implements a web server that can export arbitrary command line tools to a web based terminal emulator . . . Lock In A Sock implements a lock in a sock that can crack open the skull of anyone stupid enough to install Shell In A Box

18:04
So I asked the developer to at least add a form of Apache authentication...
just so a stupid user with test:test can't result in an a breach that I can't audit/trace
@ewwhite I prefer to take whatever is said 100% literally. I don't believe there is any ambiguity in how either of those statements is written. There is only the question of the person who reads it being capable of interpreting it correctly, which should never be assumed.
@ChrisS so my backup runs at 4GB/min instead of 1GB/min...
Where's the 300% number coming from?
@ChrisS some people would say "300% faster". Others would say "400%"
or you could not confuse people and use the numbers directly. if you want to communicate, communicate directly.
18:10
@RyJones this is benchmarking! We don't "Communicate" here!
@ewwhite 4x the speed
@voretaq7 true.
this is why we have basis points, btw
Like percentage points, basis points avoid the ambiguity between relative and absolute discussions about interest rates by dealing only with the absolute change in numeric value of a rate.
I think you should just use overwhelming force to take the sweets from Jack and John. Then, unambiguously, Jack has 0 times more sweets than John. As a bonus, you now have plenty of sweets of your own. — Ben Hocking Jun 16 '11 at 12:38
There. There's your fucking answer. And I ripped the CPU out of the benchmarking machine and threw it in the lake.
<harumph>
now I know why Lantus and all my syringes are labeled U100
@ewwhite Yeah, both of those would mean the same to me.
18:16
@RyJones US has bigger insulin syringes? I guess that shouldn't surprise me.
@Tanner same syringe, higher concentration of insulin in the solution
@Tanner different concentration, 100 units per mL versus 40
ahh
0.01ml = 1 unit
so theoretically easier to dose (U40 makes no sense to me. U50 would be sensible...)
@MDMarra wilcard support for RD services are a bit.. sketchy
18:17
@voretaq7 So ShellinaBox==bad?
last time I checked the subject name had to be an exact match - at least for RDS
@ewwhite anything that involves remote command execution via a web browser is bad IMHO
@voretaq7 would adding apache .htacces-style auth be better?
(marginally)
@ewwhite better than unauthenticated access certainly
and using TLS would be mandatory
@voretaq7 If you open right now, it gives a console login prompt.
SSL is there to protect the session flow
18:18
@ewwhite that's still pretty fucked because I can sit there all day and brute force your username/password pairs
they should use a web SSH client
but now I've lost my granular SSH auditing... logging, denyhosts, AllowUsers.
preferably one that authenticates with keys.
and my clients are buying this left and right.
@ewwhite you should be doing your auditing and access control through PAM
which means you just add those to the chain
@pauska Hm
18:20
@ewwhite And people will be hacking showing them the error of their ways
It's a single name on UAG (which is the gateway)
@voretaq7 well, the brute force issue... denyhosts is an easy thing to toss on a server with SSH open to the world
just think how long I've fought to get rid of telnet... this is a step back
can't brute-force a server with keys-only auth ;)
@NathanC sure you can. It just takes more force.
ANY system can be brute forced, given sufficient resources.
@ewwhite Make any client who wants this thing sign a big scary form saying you have no responsibility for security in the environment
and find/offer a web-based SSH/key-based login system
@voretaq7 I've tried web-based SSH in the past.. Mindterm...
18:23
or make them use Apache certificate-based authentication to connect to this thing
@ewwhite there are dozens of them, one has to not suck.
but getting the terminal emulation for the application just right is a problem.
I need 81x25, 16-color, extended fonts, etc.
@ewwhite get one that speaks VT100 or ANSI and doesn't just fucking lie about it
@voretaq7 We use a customized putty.
but Ansi25 works... SCOANSI works... some other shit
@ewwhite then you deserve the problems you have man :)
@voretaq7 I'm just trying to generate a cogent argument against leaving a wide-open web interface...
18:26
first of all 81 x 25 you're already one of those Hitler cats :)
@MDMarra maybe UAG does some voodoo tricks, but I've only published RD stuff through RD Web Access
@ewwhite It's a wide open web interface. that's the cogent argument. You're offering up a terminal for anyone who wants to try to break in.
@voretaq7 but wide-open SSH is better?
I think they dont have the right cert on the gateway config
It surprises me that in 2014 people are still using DOS-style terminals for applications...then again...
18:27
Gotta ask though - why UAG? Isn't the built-in stuff in 2012 R2 enough?
So they have the right cert on the UAG trunk but not the gateway role
checking now
@ewwhite ssh should be forcing you to use keys
@voretaq7 for root, yes...
I haven't configured a machine to allow username/password auth via SSH in years. It's either a key or OTP
but remember the application.
18:28
@pauska They use UAG to publish otehr things, so its nice to have their VDI pool available through the same portal
especially if they get SSO working
(warehouses, hourly employees, high turnover, salespeople)
@ewwhite For everyone. and root shouldn't be logging in period - you should be connecting as an authorized user and using su or sudo...
@NathanC because enterprise
make sure they have have done the portal publish thingy correct
you gotta find some template file, edit that a bit and then publish with a complete list of any kind of server or subnet involved
broker, gateway, vdi pool, subnet for the vdi etc
@voretaq7 That only exists in academia... root-login4lyfe!
18:29
@ewwhite lol, academia and also where I work
google "microsoft uag vdi" and you'll see
@pauska yeah its in the UAG config not the RDP template
The only way you can log in as root on my corporate machines is to be physically at the console.
The only way you can be root on my personal machines is by being physically at the console, shutting the system down, and bring it back up single user.
connecting works fine, its just with an extra prompt
@JoelESalas heh... Well, in my cloudy, financial and pr0ny experiences, root login was pretty normal.
18:30
@ewwhite I don't have any servers that root can log in to over ssh
@ewwhite The only thing that the DevOps Cloud people, the financial people and the porn people have in common is they all like rawdoggin' it
In fact, the most developed sudoers files I've ever made were in the produce industry.
@ewwhite They're Doing It Wrong
@JoelESalas well, I can't disagree...
itch
@JoelESalas and yet again "Banks should never be used as an example of how to do ANYTHING" :-)
18:32
@pauska they had a self-signed cert on UAG, but it was in the RDP gateway config
@voretaq7 heck, every server at last firm had the same root password
but without consistent out-of-band access and shaky hardware, I needed root console pretty often,
All of our servers here have the same root password. It's really long, you'll never remember it, and you'll have to GPG-decrypt the master password list to type it in.
single-user mode to repair ext3 because: Supermicro
@ewwhite and pinned kernels ?
:( that too
I admit, I go to all of my systems via root... but keep a sudo-enabled service account managed by Puppet.
(because I know I'm doing it wrong)
18:36
@ewwhite you're wrong and you should feel bad
@RyJones I'll flog myself with a bag of $100 bills...
also, nobody told me Lantus expires 28 days after you open the bottle, so I've been injecting my cat with non-insulin for 5 months: care.diabetesjournals.org/content/26/9/2665.full
@ewwhite if still wrapped, that could hurt
IS apache 2.4 sufficiently different from earlier versions that we should give it it's own ?
@Iain I know there was a change in config handling, let me look
httpd.apache.org/docs/trunk/new_features_2_4.html shows a lot of churn, esp wrt mod rewrite
@RyJones There's changes throughout
18:40
@Iain I think so
it's pretty substantially different
@Iain I think I'd lean towards a new tag, yeah
2-4 or 2.4 ?
@Iain dots would be preferable to dashes
done
apache2 should probably become apache-2.2
unless you guys see some egregious "no" cases for that?
18:42
I don't see one now
@RyJones I don't care about the changes, I care about the questions
If there are a substantial number of apache 2.0 questions in there I can't just rename the tag
gotcha
@Iain I think so as well.
(intuitively I don't think many folks switched to Apache 2.x before 2.2)
18:46
@voretaq7 2.2 was released almost a decade ago. 5 years before SF existed. If there's 2.0 questions around, F'em.
@ChrisS I'm going with that logic because sorting the tag is painful :-)
I totally have a box with apache httpd 2.0.52 installed on it...
multiple renamings retaggings and rewikiings completed
@freiheit you're a filthy godless heathen :-)
Anonymous
Anonymous
who'd ever think that is a good idea
18:57
@voretaq7 Nono, I definitely bathed today. More of a godless barbarian heathen...
@voretaq7 did you alias myapache2.4 - it just stopped working
RHEL4 came with apache httpd 2.0, and I still have an RHEL4 box, because terrible terrible reasons
or rather seems to have become apache-2.4
@Iain yeah I aliased that to apache-2.4 (and I'm going to create apache2.2->apache-2.2 as well)
bummer - that may be a badge opportunity lot
speaking of which I figured out how I lost my Gold Linux badge - CW all the things does it :(
18:59
@Iain it should carry over to the new name in the merge
(if it doesn't that's a bug)
