Linux backdoor squirts code into SSH to keep its badness buried

Tom 38

Re: @AC re slipstream SSH datastream

So there is a vector (possibly OS specific) that was used to break into SSH, and SSH itself is a vector to compromise whatever OS is being used. Which may be Linux.

No-one has suggested that sshd was broken in to, only that once the server was broken in to with enhanced credentials, that allowed them to install a backdoor that hooked itself in to sshd.

Re: Infection Vector?

Place your bets:

Unpatched Apache flaw or zero day Apache flaw ?

Do you even know how little of httpd executes with enhanced credentials? I would very much doubt that that is the vector.

Re: Doubt it

SSDs are the same as HDDs in the same way that HDDs are the same as tape. They all store blocks of data. You can write data to all of them. You can read back the data from all of them.

The only differences between any of them are the underlying technology and performance characteristics of each technology.

HUMANITY STUNNED - Apple Retina iPad Mini arrives. A solemn moment

WTF?

Re: Apple does it again ...

"Someone with common sense" complains that ipad is a waste because the apps won't use that power, and then asks for a 5" tablet with an i7 inside it.

"Someone who hasn't taken their meds" sounds more probable.

PS: Did you know that all Apple phones and tablets with Lightning ports come with a free USB to Lightning adapter so you can charge from USB ports? It's just like the cable you use to charge your iphone 3G, but one end is tiny instead of fat. I can see how this might upset you.

Re: Why mock?

You've got it wrong, this is just the appropriate point in the story cycle. Wait a few months after launch for the stories "Why Apple is failing to launch new things" and "Apple insider rumours insist new iphone fellates you".

It's all click bait to get the people who either hate or like apple to post, but you need to use a different lure depending upon the season.

REJOICE! Windows 7 users can get IE11 ... soon they'll have NO choice

Tom 38
Silver badge

I wish MS would abandon IE versions and disassociate it with Windows

Purely from a technical viewpoint, what they do means there is always a significant proportion of users with different versions of the browser. This doesn't happen with Chrome or Firefox, users of these browsers are continually updated to the latest stable version, but with IE, particularly globally, you will always have some clients on really old browsers.

For instance, our website has Chinese users. This means everything has to work correctly in IE 6. A minority of our XP users still use IE 7 and 8, we have lots of IE 9 and iE 10 users, and more IE 11 users.

What this means for us developers is a non-ending game of whack-a-mole as we fix an IE bug in IE 6, only to see an unintended side effect in IE 9 - it drives you bonkers.

Do they really think people upgrade windows to get a newer version of IE?

Apache is phenomenally configurable in its mode of operation. If you choose the default chosen by most distributors, you get a mode of operation - prefork - where performance does blow. They choose this mode by default for two reasons, PHP and ease of use for their users.

PHP can run in two modes, an interpreter embedded in to the web server, or as a standalone process with worker children/threads that communicates with the webserver via FCGI. In the first mode, it is easier to setup a PHP app, simply put PHP files in a directory served by the webserver, in the second you need to configure FCGI - its not hard configuration, but it is extra work. Distros prefer not to do that, so prefer the first mode, however the first mode can only run in apache in prefork mode, therefore they choose prefork.

Each worker in prefork has a PHP interpreter active in it, whether it is serving static files or running PHP apps. This means you have more interpreters 'active' than are necessary - wasting resources. Plus, you can only handle as many simultaneous connections as you can handle simultaneous workers - regardless of what those connections are doing. So prefork is a dog, and to be avoided.

Apache has other modes. We use "event", which is a hybrid thread/process model, basically the same model as nginx, and guess what, it performs just as well as nginx. Plus, we can still use the billion or so apache modules out there. We have to use a fcgi-wrapper for our web apps, but this is good anyway as it allows us to control how many PHP processes are active at any one time, which prevents you having too many DB connections, which, if you've ever run a dynamic website will know, is usually the limiting factor of any hosted site.

nginx, as a bare bones web server, doesn't have the option of the prefork model, nor of embedding PHP directly in to the webserver, so you need to configure a php-fcgi wrapper for each app, just like we do for apache-event.

tl;dr - apache not dead, read the manual and learn how to configure it for performance.

The 10 most INHUMAN bosses you'll encounter: A Reg reader's guide

Re: 10 Types of bosses

@ hammarbtyp that "small company" must have been quite big. Small companies don't have share options and are not publicly traded.

What drivel, who said anything about "publicly traded" shares? Share options can be had in any company where the ownership of the company is vested in shares, typically they are used to allow new equity investment or to provide an equity share.

For instance, Jim and Bob own a catering company, Jim has 50 shares, Bob has 50 shares. They have an employee, Phil, who is so essential to the business that Jim and Bob create an extra 20 shares, and grant an option to Phil that he can buy the shares for £20,000. This is a share option - if Phil executes the option, he will own 1/6th of the company, and Jim and Bob will own 5/12ths each.

hammarbtyp is describing a situation where Jim and Bob keep telling Phil that "you are so essential, we're going to have to see about getting you some equity", without actually doing shit. It happens all the time.

Actually it's pretty cheap for what you get. Loads of functionality is now rolled into the OS that you used to have to pay extra for.

You might have had to pay extra - these are features that MS decided to use as price differentiators - as Windows fades in to irrelevance, differentiators are not required.

You could always use Linux and pay in time and inconvenience instead

Sometimes when you are skiing, it can also be snowing. When it is snowing, the sky is white, the ground is white, the clouds (which you are in) are white. A big glowing red line in the HUD would delineate the piste from the off piste, and perhaps stop you accidentally skiing off a cliff in bad vis. Things that stop me killing myself I generally consider "useful" and not "part of the video game".

Similarly, if you're on a long piste, is that bloke in the black 1km downhill your mate, or just another person wearing black. Did they go left or right at the junction? Which restaurant were we skiing to again*?

Plus, skiing isn't necessarily sport, it's just spending some nice time in the mountains moving from place to place on skis. It's not all Ski Sunday grand slalom races y'know.

If you think Oakleys are stylish sunglasses, you are the one doing away with the style component. Oakleys are tough, the frames are titanium, the lenses are strengthened polycarbonate and are interchangeable for when even tough is not tough enough.

You buy Oakleys because you are fed up of snow blindness from the ineffective anti glare coating on the gas station glasses, and/or have sun burn from the gas station glasses filtering UV-A and not UV-B, and/or are fed up of having to replace them for the 5th time this trip because you took a minor spill.

Besides which, you would hope most of it can be put behind the mirror blue lenses.

I bet he's found plenty of developers, but his idiotic "I'm gonna be RIIIICH" plan will be ill thought out, with no way of monetizing, require a huge amount of development, for which he is willing to offer only sweat capital.

The funniest offer I got was when one of my cousins suggested that I act as his unpaid system architect and project manager, overseeing and directing a team of indian/chinese outsourced developers who would develop his "travel website". His "site" had no way of monetizing users apart from ads, and would be based around some magical algorithm for determining what you are after, which he hadn't yet come up with.

Er. No thanks.

Glad you class yourself as a bumpkin, but 200m from the exchange puts you in the middle of the locale. Furthermore, your locale is large enough that your exchange has been unbundled.

This article is not talking about you, since you are, effectively, a townie - you live in an area where you have access to multiple wholesale providers, OFCOM would class your exchange as Market 2 (2-3 wholesale providers) or Market 3 (4+ wholesale providers, fully deregulated).

This article is talking about people connected to Market 1 exchanges, where BTw are the only provider. People like my old man, 8km from a Market 1 exchange, no ADSL2+, no 21CN WBC, 2 Meg on a good day and on a bad day nothing.

The new devices do not offer the storage i want, nor are they really offering anything new for the price point... sorry Apple, but if you want to keep charging premium prices, you need to give us premium hardware.

Depends if you consider an ipad to already be premium hardware. Making the full size ipad thinner and roughly a third lighter is a premium enhancement. Giving the mini a much higher resolution is a premium enhancement. Saying otherwise is sophistry.

Not totally convinced

a) Another SAN. This time it is all ethernet, but that won't be routed through our regular switches, ergo another new SAN.

b) No filesystems. FS do offer benefits that kv stores can't. Snapshots, being able to browse, permissions, end-to-end checksumming...

c) No real difference over iSCSI or AoE and giving a raw block device to the kv store of your choice as backing storage.

d) Loss of bandwidth or ridiculously expensive adapters. Running this on GigE, you won't hit 125MB/s. Run on 10GigE, that will go up to about 1250 MB/s, and I'm not even including overheads here. Presumably you would have one, possibly two aggregated connections to the SAN switch, you're going to be hard pushed to even match the bandwidth in a single MiniSAS cable.

e) No mention of redundancy, which normally means if you want redundancy, store multiple copies on different disks. Eww.

Last living NEANDERTHALS discovered in JERSEY – boffins

Tom 38
Silver badge

Re: Interbreeding and species

This is oxymoronic. To a good first approximation, the definition of a species divide is that (fertile) interbreeding does not occur across the boundary.

If all things were nice and neat and tidy, then that would be a good definition of a species, however inter-species breeding is not uncommon, and whilst most interspecific hybrids are infertile, some individuals are not, which can lead to a new hybrid species. For example, ligers (lion/tiger) and tiglons (tiger/lion) are largely infertile, but certain individuals are not and have reproduced.

Besides which, there is a good argument for saying this it is intra-specific hybridization between H. sapiens sapiens and H. sapiens neanderthalis, both being sub species of H. sapiens.

Even if they are not sub species, interspecific hybrids forming new species is not unknown either - the Red Wolf may be (opinions differ) a coyote/grey wolf hybrid.
