IPv6 now faster than IPv4 when visiting 20% of top websites – and just as fast for the rest

Nate Amsden
Silver badge

Re: Time to learn

one of my ISPs is Hurricane electric (co-lo in fremont facility just a 1U server though I have a 3rd of a rack, power limits prevent me from using more though). They asked me if I wanted IPv6. I said...NOPE. don't need it. They did give me some IPv4 IPs, I think I got 6 or something (running vSphere on my server with a few VMs on it, also running an openbsd firewall inline in front of the VMs which does NAT for other VMs that don't have external IPs). I do like the 100meg unlimited connection I have with HE though, I proxy most of my HTTP/HTTPS traffic through the colo.

I see what you say about IPv6, but if I am going to play around with things I'll go play Fallout 4 or something, playing with IPv6 "just because" doesn't sound remotely fun or interesting to me.

20% is not noticable

20% of anything generally is a rounding error for me. 20% faster, 20% cheaper, 20% more efficient.

I just checked my AT&T phone again, it is not roaming, and is assigned an IPv4-only IP 10.xx address. www.whatismyipaddress.com says I am coming through a proxy server(or perhaps carrier grade NAT maybe they don't differentiate). Never had a problem accessing things even with tethering.

I just spent 3 months in thailand, didn't happen to notice what my phone with a local SIM card was assigned if it was v4 or v6, but more than anything the latency(purely distance I imagine) killed performance, I managed to get somewhat better web performance tethering and going through a VPN and proxying my HTTP traffic through my co-located server in California, though not for geo-diverse sites).

Myself I have no interest in IPv6, I do not have any plans to deploy it on any of my networks, if it happens to get deployed in a transparent fashion upstream on my mobile or broadband connection I don't care since it is transparent (I do not make inbound connections to my phone, and any inbound connections to my broadband are done through a VPN established outbound to my co-located server so I don't need static IP and don't have to care about NAT that the ISP might be doing).

I figure if at some point I really need to support inbound IPv6 to the websites that I manage then I'll have that translation handled by the CDN (just like they already do things like SSL termination and TCP optimizations already).

The die hard IPv6 fans remind me of the modern web developers who want you to jump on the new thing just because.

I would put IPv6 up there along with Software defined networking(SDN) as something that can benefit large scale companies well(mainly service providers), but for 95% of the downstream organizations it provides no benefit.

IPv4 addresses are available, getting large blocks of them may be difficult, though every company I have worked for in the past decade hasn't needed more than a few dozen external IPs at most (even today not hard to get). Smart use of NAT and name-based virtual hosting(with good proxy servers - in my case Citrix Netscaler or F5 BigIP) goes a long way.

Now that SNI is pretty widely adopted that removes a large reason to need a big number of IP addresses on servers with multiple SSL certs(covering multiple domains so a wildcard cert wouldn't be sufficient).

Die hard IPv6 proponents say IPv4 is full of hacks and brokeness so we should upgrade because of that. The hacks seem to work fine, I suppose if you are directly suffering from those limitations then you should probably upgrade, myself, I really haven't had any pains associated with IPv4. For example the last time I was at a company that needed a site to site VPN with another company and we happened to have overlapping IPs so had to do 1:1 NAT -- that was literally 11 years ago).

Myself I don't do peer to peer anything and the VoIP solutions I have used seem to work fine with IPv4 and NAT etc.

So no pressing need to upgrade, I don't see a pressing need for many years to come(for folks like myself anyway).

Explo-Xen! Bunker buster bug breaks out guests from hypervisor

Nate Amsden
Silver badge

Re: Please be more critical of the Qubes project

I do not use KVM but did not believe the claim that it is a type 2 hypervisor, did a quick search and came up with

https://www.ibm.com/developerworks/community/blogs/ibmvirtualization/entry/kvm_myths_uncovering_the_truth_about_the_open_source_hypervisor?lang=en

"Myth #1: KVM is type 2 hypervisor that is hosted by the operating system, and isn’t a bare metal hypervisor.

This is a persistent myth, but the truth is that KVM actually does run directly on x86 hardware. People assume it is a type 2 hypervisor because one of the ways that it is packaged is as a component of Linux - so you can be running a Linux distribution and then, from the command-line shell prompt or from a graphical user interface on that Linux box, you can start KVM. The interface makes it look like it is a hosted hypervisor running on the operating system, but the virtual machine is running on the bare metal - the host operating system provides a launch mechanism for the hypervisor and then engages in a co-processing relationship with the hypervisor. . In a sense, it is taking over part of the machine and sharing it with the Linux kernel."

I assume the misconception is similar for those people that think Vmware ESX/ESXi runs on top of linux because they see linux messages on bootup.

(Vmware customer since 1999 - haven't seen anything in Xen or KVM that has gotten me interested in evaluating them as alternatives - Linux user since 1996 so not like I don't have experience with open source stuff)

Re: No central provider.

scalr was crap 6 years ago

Regular outages and screw ups. The concept was interesting just implimented poorly (same goes for EC2)

It was cheap though. I recall rightscale wanted more than 50,000 dollars a month to do similar things as scalr which was a tiny fraction of the cost. Company was spending about 400k a month on cloud services. Recipe for success there.

If it was up to me I wouldn't use either. Company i was at imploded years ago so not really a concern anymore

Containers rated more secure than conventional apps

Nate Amsden
Silver badge

big caveat there

Anything will be more secure if you "do it right", whether conventional/legacy or containers. Many conventional/legacy systems could be much more secure without even thinking about containers but generally companies are too understaffed or under equipped to handle changes in the face of everything else that is going on at a given time.

For the vast vast majority of use cases simply having single use VMs is more than adequate, a reasonably secured base OS with one app running in it (along with whatever base services you might need e.g. ssh, splunk agent, monitoring agent(s) or something). The overhead is really minimal.

Of course there are crazy people out there that want to be spinning up and down constantly, which is just overkill for just about everyone else. Most workloads are not very dynamic in nature(coming from someone working in more or less SaaS services for the past 13 years across many companies, none of which I would consider were using "legacy"(or "conventional") applications).

Some people like to THINK they are dynamic but in most cases the amount of variability isn't very extreme at all to warrant overhauling everything for a fully dynamic environment(which is a massive investment).

There are exceptions for everything of course, no one solution fits every problem.

I do use containers BTW, in production even(for about two years now with good results). Though the containers are generic LXC containers(that to a system admin look more like a VM than what one might consider a "container"), not docker. Looking to expand on the use cases of containers after the success we have had. The main benefit of containers at my org is to be able to oversubscribe a host and have the containers be able to instantly scale up and down(because they have no restrictions on CPU) based on load(while removing overhead of a hypervisor and licensing costs of hypervisor). Of course we use only similar application loads for a given container host, and we have data that shows the likelihood of one system overwhelming all others on the host has never shown to be a threat in the past 5 years(or anywhere close to one).

For everything else it goes in vmware which is of course far more flexible with networking, storage, and resource limits.

question on google nexus

I think I know the answer but would like to know anyway.

If a user is using a nexus on android 4.4.4 which is still supported from what I see would they get security patches for 4.4.4 or would their only option be to upgrade to 5 or whatever the latest supported build for that device is (assuming it is newer than 4.4.4).

I assume the user would be forced to the newer build. But maybe that is not correct.

It's not as if they have no CPUs. Their gen 5 high end flash box has 128 2.5ghz xeon cpu cores and 16 ASICs (across 8 controllers) sitting next to 3,500GB of cache.

It's rated for 75GB per sec reads and around 30GB per sec writes(to/from servers), posted good SPC2 numbers a while back no SPC1 yet though. It will get faster in the future as the software is optimized further for the Gen5 ASIC.

Seagate axing 1,600 staff amid PC sales slump

Nate Amsden
Silver badge

Re: Seagate might invest in Linux to offset PC sales slump

Sounds like a pretty terrible idea, I say that as someone who has used Linux (and continues to) for the past 20 years on my desktops and laptops (currently Lenovo P50 with Linux Mint/MATE 17).

Seagate makes storage, changing gears to start making servers or desktops is just a bad idea, and trying to make desktops with Linux on them even worse.

People are obviously more likely to switch to Mac than Linux if they don't want windows 10. The more technical bunch like myself will refresh their computers before windows 7 can no longer be sold by OEMs (October 2016 I believe) to maximize the life of windows 7 (I dual boot though 99% of time is spent in linux, I do use a windows 7 VM for work related things as well while in Linux).

Back in the late 90s I too had high hopes for linux on the desktop, there was certainly a massive opportunity, but the community building the software kept shooting themselves in the feet (a practice that continues today, with no signs of changing - biggest issue is driver ABI stability in the kernel).

Then IOS/Android tablets came out and gobbled up that entire market opportunity that was there for Linux on the desktop. Of course Android uses Linux underneath but it's really just a shell, so to me I don't really count Android as "linux" it seems to share practically nothing in common (from my perspective as an end user) with what I get with my regular linux laptop or servers.

3PAR released something similar about 3 years ago, but it was specific to I/O optimization not data storage, specifically optimizing the I/O to and from SSDs to minimize wear and maximize efficiency, also improved bandwidth efficiency as well.

You could google for "Adaptive Read Caching" and "Adaptive Write Caching" for HP 3PAR for more info on the topic(you could throw in the google search term 'techopsguys' for my blog post on the topic back in 2013).

capacity licensing

is pretty old isn't it ? HP has had it with 3PAR for years, and 3PAR had it on their own for years before that. I have little doubt that EMC and HDS and others have it as well.

I don't think it is very common, but the option has been there for a long time.

HP even has a "Facility as a Service" where they will go so far as build you your own data center from the ground up(at the time 150kW was entry level) and operate it for you.

They also have a "Flexible Capacity" program which is sort of capacity licensing for severs/networking/storage(I assume basically anything data center related) as well.

Though I'm sure FaaS and Flexible capacity are not well known, when HP told me about them at Discover 2 years ago I had not heard of them myself.

Does it even make sense to buy a VTL today?

Nate Amsden
Silver badge

you referring to tape in general or VTL specifically?

Because to me tape in general is still useful. The distinction between OFFLINE and OFFSITE. Wouldn't want someone to fat finger a command and delete all data and all backups(or an attacker do it). With so many things driven by an "API" these days it's easier than ever, more so with cloud services.

Having to have a human physically insert a tape into a library in order to access it is appealing to me anyway. Not to say that tape is the only backup, having onsite (online), and offsite (online) backups are still very useful but as a last resort I still consider it a good idea to have offline backups as well, after being written to physically disconnected from any level of automation that would allow it to be destroyed remotely -- whether that is on tape or another medium doesn't really matter though tape seems like the most likely target.

Lenovo cries 'dump our support app' after 'critical' hole found

Nate Amsden
Silver badge

Re: Sigh

my real user review of the Lenovo P50 is it works ok(about $3600 loaded up including 3 aftermarket Samsung SSDs and 4 year on site support). 98% of the time in Linux(with a windows 7 VM for some work things), 2% of the time in Windows 7(bare metal).

I think if you don't want the crapware you most likely have to pick a small OEM that installs vanilla software. For me it was more important to have on site support so I wanted a big name vendor. Previous laptop was toshiba (bought in 2010), worked fine though support was a year expired and I didn't want to risk my primary work machine being without support anymore.

Vulnerabilities like MITM to me are such a low threat level for most users it's just a knee jerk reaction by people a lot of times. Most technical folks will practice relative safe computing habits(I don't recall being infected with a virus or malware since roughly 1992), and hopefully not using (m)any public wifi access points to reduce attack vectors.

Less technical folks are likely to be compromised 100 different ways before anyone does a MITM attack against them.

I remember my grandfather before he died was apparently addicted to granny porn. He bought a Dell computer, would go to the porn sites, get infected, then after a few weeks or whatever the computer became mostly unusable, he would call up Dell, they would remotely reinstall the system, and he would go at it again(this was about 8 years ago maybe).

Windows 7 OEM end of sale date is coming up pretty quick (end of Oct 2016), and even now it can be difficult to find systems that will ship with it. MS has worked with big players like Intel to ensure lack of compatibility going forward with older Windows systems on new hardware, my company's PC supplier told me some horror stories about their customers rushing to stock pile compatible equipment before the hardware is no longer available(sometimes literally selling out while they had them on the phone).

LinkedIn mass hack reveals ... yup, you're all still crap at passwords

Re: Time to...

And move to what ? I have never had a facebook or twitter account but I do use linkedin. Though all of my info is "public" on linkedIn(just career stuff) so there is really nothing to compromise data wise(I believe linkedin had me reset my pw back with the original breach(?)).

I don't use linkedin for MUCH(though I am a premium subscriber), it has gotten me tons of career leads over the years(none of which I need right now), and really if just one of those pans out again in the future(little reason to think it wouldn't) it would of paid for itself right then.

In general I'm not a social person so being able to stay "connected" to the people in my career is handy.

I was thinking more along the lines of it shouldn't take much work to block such simple passwords from being used in the first place. I don't advocate requiring really strong passwords for something like linkedin, but people shouldn't be using 1234567 etc (unless I suppose it is a throwaway account or something). Maybe linkedin has already implemented this since this data is pretty old already.

Storage array firmware bug caused Salesforce data loss

Nate Amsden

zfs to blame?

My experiences with zfs and corruption were very frustrating. This was on OpenSolaris. I was expecting a simple tool to just clean the corrupt blocks and mount the FS like any other fsck. But no it went to immediate kernel panic and a reboot loop.

With Oracle i would expect it to roll back trx that were bad.

I was at another company a long time ago where we had oracle corruption caused by both controllers in SAN failing at the same time.(the SAN admin blamed himself for misconfiguring the controllers to allow that to happen. To this day I can't imagine why a system would allow you to configure it in such a way) About 20hrs to recover from what I recall. Though we were still seeing the occasional ORA-600 or something error that indicated a corrupt part of the DB more than a year later. They had no really good backups either. They got budget for real standby servers after the incident though.

The tools to deal with zfs corruption were very immature at the time(maybe 4 yrs ago). It seemed to be generally regarded as voodoo to repair zfs corruption. There were things i tried at the time i don't recall what it was a while ago. Nothing helped all data lost.

Fortunately the data was a collection of backups so nothing really was lost other than downtime from the panics and tracing down the cause of the panics.

The system was a nexenta HA cluster that went split brain. Both nodes tried to write to the same volume and bam it imploded. Nexenta support immediately said we were fucked and to restore from backup. They refused to offer advice on the zfs tools used to try to repair the system.

After 2 or 3 incidents of this we disabled HA until we could find a replacement solution.

Re: So Much hatred...........it leads to the dark side

If google didn't do what they did it is likely android would not be in the market leading position it's in.

Apple of course had millions of customers ready to gobble up the first iphones. What did google have? Not much. Microsoft was able to get full control of their phone platform (i think?) But of course nobody uses it.

Webos was the same. BB10 the same. Firefox OS the same (i assume).

For all the doom and gloom about android vulnerabilities I've yet to read about wide scale expoitation. Usually the stories are crap coming from dodgey chinese sites targeting chinese users.

I don't pay close attention most of my tech news comes from el reg. Though I believe if there was serious exploitation going(not involving manually instaling apks or non main stream app stores) on there would be articles here about it.

Every once in a while some security thing comes up that affects a few apps though usually it is yanked from the stores pretty quick.

Android updating won't be fixed in my mind until there is the ability to roll back any upgrade(app or OS) easily. There have been several apps I have updated only to find them worse than before with no way to go back.(I supose one exception is the built in apps. I was able to downgrade samsung S health this way.

what he said

I used openfiler a decade ago with some spare HP JBODs for some dev workloads. As long as it worked there was no issue. Forget about upgrading though(I recall the uograde path at the time was basically full data migration to avoid loss).

I tried nexenta a few years ago as JUST a NFS solution for small file set (under 1TB). On paper seemed ok. In reality it sucked hard, made worse by non existent support (yes i paid for their support and professional services to certify the configuration). I have since heard nasty insider stories about ZFS solutions in general which make me glad I have never considered that as a viable solution. I use ZFS at home and it works fine. And I'm sure it has it's use cases at larger scale as well. Keep it away from my vmware and mysql databses though.

Not even solutions like pure storage are mature enough for my liking.

The more i have learned about storage over the past decade that i have been using it more closely, the more conservative I have become in deploying solutions.

I just need it to work without fuss, and for me and my org's mission critical data that means 3par on fibre channel(3par customer for 10 years now ). My experience with 3par is certainly not flawless by any stretch(no solution is perfect). That just reinforces not being interested in taking risks with any other block storage system. My feature usage of 3par is quite limited which probably means I encounter fewer bugs). I love the core of the platform that is very very solid.

Now if HP only had a decent NFS offering (storeEasy and storeAll don't count). 3PAR NFS is a combination of not mature enough and requires special controller versions that only 1 of my 4 arrays happens to have. Even if all my arrays had them I don't believe it would do the job for what I want.

If i was at a larger org we would have more flexibility in testing other things. As-is every piece of storage and server and networking is mission critical(all workloads whether development or qa or testing or production are all consolidated). I have no lower tier of stuff. Maybe at some point but not yet.

For a while we were pumping 200 million in revenue through 8 DL385G7s (384GB with vmware) and a single small 3par array. Today we are bigger for sure. Not big enough to justify segmented servers or storage though.

systems like 3PAR (I think XIV does something similar though last I read they were limited to RAID 1 only, XIO did something similar too they distributed RAID over individual platters from what I recall, so you could have a platter fail and keep using the remaining platters in the disk(systems sold with enough capacity that this was transparent), which is one way they were able to go so long without any disk replacements), distribute RAID across many disks, so you could have dozens or even hundreds of disks rebuilding data in parallel, meaning faster recovery times, and lower latency.

Enterprise class arrays often protect against an entire shelf of disks failing as well(for 3PAR this is the default). So you can lose many drives(as long as they are the "right" drives). Enterprise systems go above and beyond even that and typically only rebuild the data that is written, reducing rebuild times even further depending on how full your system is. I wrote about this more in depth 6 years ago (http://www.techopsguys.com/2010/08/13/do-you-really-need-raid-6/)

Also most/all enterprise systems proactively fail disks before they completely die. Though that certainly doesn't catch all failures, I would wager it accounts for a decent amount though.

SSDs seem to be more optimized for IOPS rather than throughput, short of NVMe SSDs at least, from what I have read anyways SSDs aren't all a million times faster on sequential operations(RAID rebuild) like they are with random operations.

HP at one point said something like 90%+ of the SSDs they have sold were still in operation in the field. Results like this is what helped them decide to offer a 5 year unconditional warranty on all of the SSDs on 3PAR (maybe other platforms too).

my company's first all flash array was a 3PAR 7450 which came online on 2014-11-04, according to the system, from an endurance perspective (initially used the 2TB SSDs, since added 4TB as well), the system is reporting the 2TB SSDs have 98% of endurance left, and the 4TBs installed late last year still have 100% of endurance left. These are for what are otherwise designed to be "read intensive" SSDs, though HP (and others now too) support any workload running on them(HP doesn't market them as read intensive), no restrictions.

Opera claims 50 per cent power savings with browser update

I have to askm. W T F are you needing 200 tabs for.

Most i ever have open is MAYBE 25 (across 3 browser windows)

I think much more than that and my Firefox would explode.

I haven't tried on my new lenovo P50 laptop but on my nearly 6 year old Toshiba (i7 dual core with HT). I was forced to restart firefox after maybe 1.5gb of usage. It would just slow to a crawl (64 bit of course). I do have a very old user profile (about 10 years worth of data)

So im sure that is part of it. I don't want to lose the history or cookie access lists (12k+ sites). I know firefox retired the cookie feature i use so not sure what I will do when i get around to upgrading

Even with gigs of free memory. Oh and this is on Linux mint. Maybe it works much better on mac or windows. I have a windows VM but web browsing is generally limited to work related things on it.

I don't use chrome. But if firefox continues to go full retard I may as well switch(to chromium ) because they will be chrome.

Virtuozzo to build full container stack, target the data centre

I read a bit of your link and see nothing of interest. What is so interesting to you there. It seems like nothing more than a generic hypervisor running on top of openbsd.

I've been using openbsd as a firewall off and on for about 11 years but don't see a useful role for it outside of that for anything I deal with anyway.

Not that I care about virtuozzo or however it's spelled either.

Hackers' paradise: Outdated Internet Explorer, Flash installs in enterprises

not the only one

But it seems folks similar to you are very vocal about every tiny little security flaw.

If security fixes were acutally just fixes instead of new versions changing and breaking other things people would be more inclined to patch more often.

Firefox is like this of course. Windows 10 is like this as well.

Android too. I have been using android 5 more on one of my phones and really dislike it compared to 4.4 on my other phone (phone hardware is identical).

Flinging Slack at them won't get team talking – senior Etsy engineer

I see the linux slack client pretty regularly chew up to 4GB of memory before I kill it. It works pretty well in general. I don't really use any of the fancy stuff(others at my company do) I just treat it as a dumb chat client, since that is all I need.

windows phone on arm

How many windows phone models shipped with intel cpus?

I think the number was quite small if there were any so intel dropping support shouldn't matter MS wasn't using them anyway
