@qroberts Networking stuff is generally going to be standardized. It's not like Cisco has its own idea of what a subnet mask is. Furthermore, Cisco is big enough that other companies tend to emulate them/rip them off
One example that happened last week for instance, one of our clients has a custom built CMS that they distribute to their clients for webhosting etc. I found a SQL injection in it, which applies to ALL their clients websites. I know the founder of the company through meetings etc and let him know. Their lead programmer called me instantly and had me explain the problem.
I'm more of an assembler kinda guy, I use to do a lot of reverse engineering for making cheats for games
@ewwhite From a comment: "If you can't name two things you're regularly doing outside of work, you're spending too much time there." Does it work the same way if those two things are drinking gin and throwing rocks at old people?
@MikeyB That's gonna be strange... will they mandate rounding up or down? If I'm a big merchant, I'm gonna report that I always round down and pocket the difference...
@MikeyB It's a sad fact of living in this modern world that you're already tracked. I don't mind that really, but I do mind if they sell that shit out. So I know that every time I use my credit card at the supermarket, because I use the same card all the time, they know that Mr 5404574125414121 always buys a roast chicken from Carlingford on Thursdays, but he spends between $150-$200 every saturday at Baulkahm Hills and 2 years ago started buying nappies
In fact I read an article about WalMart sending personalised coupons to people that their stats said were expectant mothers, and they were freakishly accurate so much that one man cracked the shits because WalMart knew his daughter was pregnant before he did
one of our larger clients is in the building industry, so as soon as a hail storm hits in a particular area, they look at all the previous repairs they did for hail storms in that area and stock up on roof tiles/etc that are commonly used in that area within an hour of the hail storm hitting, before stock runs out and prices go up
They also discover alls orts of interesting things. They were purchasing at retail prices something like 100 "corinthian" doors every single week, so they wholesaled 1,000 of them. Bam, the cost of finding that out just paid for itself 3x over
Anyone want to recommend reasonably priced horizontal cable management with pass-through holes? You'd think it would be cheaper with holes on account of less metal, but no.
@MilesErickson Im guessing they make them without holes, then punch holes in them. Meaning you ahve to pay for them to make the hole and recycle the material
I've had that sort of thing happen with VirtualCenter's Oracle DB log when VC was upgraded. Apparently rewriting all the data make it generate hundreds of times as much log as there was original data.
@Joel If you don't have access to what you need to quantify the potential losses associated with downtime, how in the world can you give them the information they need to make reasonable business decisions about risk management?
@Joel I mean, even if you're doing IT for a 20-person shop, that's really what it comes down to. Is the cost of not doing X likely to exceed the cost of doing it? Even if not, will failing to do X expose the enterprise to an unreasonable risk of catastrophic losses?
@Joel Well, if you have any external auditors, tell them about your access issues when they're asking you what your password length setting is... auditors like to be the good guys and will call things like that a "finding"
@MilesErickson I don't think you know my backstory. My company did devops before it was cool. Then they hired me to fix it. A lot of this is new ground for them
@MarkHenderson Pfft. My mother had a life career as a trauma nurse. She's now the shift supervisor. In her early days, she once played "Another One Bites the Dust" over the PA when a patient passed.
The idea is: A chimpanzee somehow got in the server room and is swinging on racks, pulling cables and otherwise making a mess. How long do you have to subdue the ape before downtime is achieved?
She said people will think twice about going to the hospital for treatment out of fear they’ll be made fun of or mocked by staff. - yeah but, they're mocking you in the lunch room ANYWAY. Same as you're mocking people dressed in purple parachute pants when you're safely in your car, or you mock the people on Jersey Shore, or you mock people who live in trailer parks.
In the USA, people think twice about going to the hospital for treatment unless they're 65+ or on the dole because they know they'll go home with a $40,000 bill whether they have insurance or not. I don't think fear of mockery has much to do with it.
@Joel In truth, I probably would use food to lure it out of the server room and into an open office area. Then I would lock myself inside the server room and start cleaning things up while everyone OUT THERE figured out how to convince the cops that there really was a chimp on a rampage.
@JeffFerland Well if that's the case, if everyone just independently queries it from the authorative server and from other servers, then I would agree it's definately not propagation.
@IlariKajaste If I make changes to my zone, the only places that exists is on my servers hosting that zone. Until someone queries for that name and it becomes cached, yeah.
I installed Debian (2.6.32-5-amd64) on my HP ProLiant MicroServer (purchased recently.) I also added 3 2tb hd in zfs. I've experienced several server froze. Sometimes it showed Soft lockup CUP stuck for 61s! Today I experienced a different problem (I think) and the message looked like this
[4313...
@ewwhite The problem is people expecting it to work perfectly on Linux when it is known not to be production-ready on anything except Solaris, Nexenta, and possibly FreeBSD.
@IlariKajaste OK, so you need chat.stackexchange.com? First you ask the .com name server (which is seeded in the root hints file). That gives you the stackexchange.com servers. Then you ask those servers for chat... (well, you don't. Your DNS server does).
I have an ME1 save, but no longer have access to the game itself. I wish to start a new game in ME2 (Xbox 360) based on this save in preparation for ME3.
I haven't started the playthrough yet and am wondering how I can tell who I had a romance with in ME1? This will determine how I will make my...
but then you end up with someone complaining about the OOM killer on their Debian server running ZFS in a situation where they should have just lived with XFS....
I am married to Camila from Riverwood, and I realised I would prefer being married to someone who acts as a follower.
I don't want to get a bounty or be confronted the guards of Whiterun whatsoever, so how do I kill her discreetly? I'm not going to slaughter her in public.
@JeffFerland I don't think I still get it... There's an authorative DNS server for each of those (www.example.com, example.com), right? And they could be different?
@MarkHenderson I think I've been rather lucky with my daughter. She's VERY eager to learn and do things herself and I've been able to properly reason with her since before she was 2.
The question is, if I've made a change to the authorative server, when somebody's (ISP's) cache expires, will they (or their ISP) get the new data directly, or will they be more likely to get another cached old data from somewhere else?
Because if it's the latter, then that does cause a propagating behaviour for the change.
@MarkHenderson Yeah, I do think it's possible my daughter understands pretty much only that "Ok dad is now explaining something to me, that's good, makes me feel so awesome that he thinks I can understand it. Also, this request he's making apparently has some point and is not whimsical, so I'll feel very very adult if I now follow that request" :D
@IlariKajaste OK. Imagine you have a workstation in a typical Windows domain.
@IlariKajaste You type "serverfault.com" into Google Chrome. Your workstation sends a DNS request to a local DNS server, which is almost certainly a domain controller.
@IlariKajaste Your domain controller might or might not have an answer in its cache.
@IlariKajaste If it doesn't, it's going to ask a forwarder, which may be a DNS server at the office's ISP. It too may or may not have a cached response.
And if the ISP doesn't have it in cache (that is, the cache is expired) then does that ISP ask it again from some other server that may have it in cache?
@IlariKajaste Here's the thing: even if you don't agree that it's a misnomer, you shouldn't use the word "propagation" because its use suggests an unsophisticated understanding of how DNS works.
@MilesErickson The question is, what information - to a professional sysadmin - is the word "propagation" expected to imply or leave out that some other word or explanation would not leave out or imply.
@MilesErickson But that is just a social issue, and in that case it would also be a self-fulfilling prophecy.
Maybe professional sysadmins have some other connotations to "propagation" that people outside their group (me) is not aware of?
Could it be the case "propagation" has siglthly different, or at least more specific, meaning in professional lingo?
Because to me (not a professional sysadmin) the word "propagation" (in connection with information) means a gradual, networked pattern of information spreading. And only that. So if the information in question is a DNS change, that would then fit right into that meaning.
@IlariKajaste There is no question that the pattern of information spreading looks like propagation.
@IlariKajaste Of course, that's why people like to call it propagation.
@IlariKajaste Here's the thing. If you register a new DNS record for something that no one has looked up before -- say I create a subdomain puppies.mileserickson.com -- it is available to everyone in the world instantly.
@IlariKajaste There is no "propagation" delay.
@IlariKajaste So, do DNS changes take time to propagate?
@IlariKajaste No, they don't. Outdated DNS information takes time to expire.
@IlariKajaste Yes, that's why we get hung up on it.
@IlariKajaste Clearly, there is no such process. A new DNS record is available instantly, unless someone has tried to look it up and there is a cached negative result.
@MilesErickson Yes, and I woudn't say that a new DNS entry propagates, only that a change does.
@MilesErickson Ah, but if we're talking linguistics, we do prefer to behave like most people, even if we'd rather imply that we want to stay culturally separate. :)
@MilesErickson Yeah, but I'm not referring to those people that don't care. I mean I bet the only differentiating factor between people who consider the term "propagation" to imply a method and those that see it as a pattern is whether they're professional sysadmins.
@MilesErickson ohoo, oh, jokos on ookoo jos kokko kokoo koko kokon kokoon?
@MilesErickson Well, I'm going to reword myself when talking with sysadmins. And really, if I talk about DNS changes, it's probably going to be sysadmins I'm talking with. :)
@IlariKajaste I think that the next time I'm traveling in some remote yet over-touristed part of the world and a tout asks me where I'm from, I'm going to say Gibberland.
@IlariKajaste And I think it's fair to say that bonfires propagate.
It's the first annual Security.SE DEFCON meetup! It's your excuse to go this year! DOOO ITTTT
