Netgear XAV5001 500Mb/s powerline Ethernet adaptor

try crossover between 2 machines first

Sir Runcible Spoon,

Try linking your ethernet cable directly between two machines and see how fast it goes (you will problably have to set up ip manually though as no DHCP server and you will have to connect to each other by typing the ip address. This takes out all equipment just to see what your best speed is.

Then also change on both cards your MTU to 9000 (providing your cards support jumbo frames). Doing this on between 2 macs usually get's around 80 to 90 MB/s. Do note sometimes when altering MTU connection goes a bit flakey though usually unplugging the cable and replugging it gets them to sync up a bit quicker - note setup has to be done on both machines.

If the switch also supports jumbo frames then afterwards can be left like that. If they are transmitting to each other over IP then those speeds can be obtainable.

350Mbps though is around what I'd expect a gig network to do without changing to jumbo frames etc... it has to do with what buffer the card has and how many packets per second it is able to process. When MTU is at 1500 which is the normal default for 100Mbps a packet has 1500 bytes in total. Of this 53 bytes is overhead so actual packet is 1447 bytes.

If the card/pc combo can process say 40000 packets per second then that becomes 55 Megabytes/second. This is raw ethernet though and the packets will additionally be wasted by the protocol - ftp usually being the leanest hence the fastest. Packets per second on Gb max is 1.4 million per second though it's not just the card but the OS, cpu speed and bus speed the card is plugged into...

if MTU is upped to 9000 though then the packet should be around 8947 bytes x 40000 in theory would get 341 Megabytes/Second but the ceiling is 100 Megabytes/second.

Of note most home routers cannot come anywhere near such packet switching speeds (usually they max out at around 4000 pps as the processor clock is the limiting factor though this would only effect routing to the internet or between ethernet and wireless).

ps I'm using rough figures the numbers are ballpark not spec accurate... It's mostly figures I see by observing ping flood responses when I put in a network to see if there are any bottlenecks anywhere. I'm not a routing engineer...

Skype bug gives attackers access to Mac OS X machines

Execution permissions

I've been trying to allow execution on specific folders - though at the moment it's been a bit of a fail. I'm now thinking to just deny all execution from any user folder which would solve this problem...

and not allow any user from writing to any directory outside the the user folder...

Normally needs a mac os x server but hopefully will be able to extract the changes to implement without an os x server.

I've always thought being able to just drag apps and run them from anywhere (any platform) can lead to bad things... execution should be locked down by default...

Floating website, hidden 'get' bills

or hetzner...

49 eur a month though there's a setup fee of 150 gets you a quad i7 with 8 gigs of ram and 5TB of bandwidth a month.

By the time you get utilisations and scalability are an issue it's cheaper just to get more servers.... I don't see the cost benefit to this cloudy stuff at least at it's current pricepoints... Can couple with cloudmin as well to make your own cloud ...

Actually this reminds me of Ken Livingstone and traffic lights / Congestion Charge of rephasing to silly timings prior CC then setting them back.. did MS have any involvement?? heh..

FTC and DoJ toss-up on Apple subs plan 'probe'

Dino
Alert

not exactly the same...

as in completely different.

The transit in this case is analogous to the whole infrastructure that delivers apps... It would be ok for apple to charge 30% if that was the agreement, based on you getting the transit for free with free fuel all other running costs. They just take a cut of 30% of the revenue instead.

charging 30% on subs though and not allowing other channels to undercut stinks anticompetitive to high heaven though... - I'd ignore it and see what happens.... say still provide through itunes but also go to web site for a cheaper offer...

Thing is it's more common place than thought - ebay has such stinking rules - though nobody follows them thankfully... They should be looked at as I'm sure they are breaking anticomp eu rules...

re depriving the tax --

I'm having a hard time getting my head round this.. is it possible this isn't correct and the bbc is wrong about this? Seriously if there's any basis on this shouldn't this open the way for a massive lawsuit against the government?

apart from wasting fuel and increasing co2 emissions which supposedly the gov has had as a target in one way or another since long before 2009, it causes other damage to vehicles, frustration not to mention loss of productivity.

How about we sue for lost earnings, extra wear and tear on our vehicles , extra fuel consumption and even extra wear and tear on the roads themselves.

Am I the only one seing red here?? It's like me, a system support engineer, creating faults on the network so that I get more callouts afaics.

But also if true this is just monumental stupidity, even if we say that its' ok to want to increase tax revenue by any means necessary - this would in fact have the opposite effect as everyone would just reduce travel by car because if taken to the extreme and just having cars waiting at lights all day then people will stop using their cars (if they haven't burned down all the lights in the meantime)

I've often wondered though how they are meant to be synced - cause most of the time there is a wave of green to be had if you speed - and sometimes excessively over the speed limit and sometimes end up doing it not because I want to speed, but because I just cannot stand waiting at traffic lights...Seriously I think I'm gonna start asking questions about this ... Where to write the FOIA requests on this I wonder??...

farcical really

If I go around war driving and capturing all data and get caught I'll get thrown in jail..

Large company?? oh lets share the loot and pretend we're doing something about it...

Also would it be unreasonable to assume that the kit doesn't discriminate between unencrypted and encrypted traffic? it could just be capturing encrypted and unencrypted traffic and they are just saying well we can't read the encrypted stuff anyway..

Given that a lot of traffic in general is already to google whether it be from it's services (search, email dns etc) or from ad-sense or analytics and since it knows what the traffic is to itself could it not correlate that with the encrypted captures and could give it a hand in deciphering the encrypted stuff also? It would have to sync the stream to an accurate time source - and it definately has that as there's an active gps recording position at the same time.

Paranoid ? That's what they were saying when the Germans were poking around google asking what they've been up to then suddenly this came out...

Broadband boss: 'The end of freeloading is nigh'

Dino
FAIL

He is right but he is also mad

Ok he is right - I completely agree that all you can eat data is not sustainable. There is a clear cost to every byte that is consumed.

However his suggested price point means he needs to be locked up in the mental asylum and the key thrown away.

I currently get 1 TB /month for 14Euro a month at my data center. (first 1.5 TB is free). This I get at 'proper' un-congested data rates. if don't upgrade to extra data and just stay at 1.5 TB which is free I am on a 100Mb circuit. I've frequently passed images, backups etc to other sites across the world and easilly get 95% and over of the bandwidth (so it's not just theoretical). If I buy even one TB per month extra I can then get a Gigabit network connection.

I would have no objection to a pricing structure like this.. Infact I'm currently on half the bandwidth (50Mb with Virgin) at home and 100 times less upload speed and pay 30 odd pounds a month.

The german datacenter (hetzner btw) I pay 49 euros a month, I get a decent speck server thrown in and damned good network connections.

So the equivalent .... I'd say 8-9 TB free per month should about balance it out as virgin offers such a lower network capability in comparison, the service is nowhere near as resilient and equipment provided is probably an order of magnitude or two less expensive than that provided by a data center (completely making it up but lets start at that point...)

9TB/30 days = 307 GB per day .. that's fine. (such a figure is about 65% utilisation running 24/7 non-stop)

Where's the problem? I'll pay... Infact I've already paid so where's my data?.

Those fuel prices are bogus

There are a lot of bogus fuel prices. The data is constantly out date and to report them they insist on submitting a form with long/lat coords of incorrect prices.

I have found several (12 in london) that prices are impossible and the top 5 don't even exist.

I then tried to find cheapest fuel coming back from gatwick and found one just off the M3. The price showing on the tomtom was 9ppl cheaper than reality and my neighbourhood BP which is usually not the cheapest around was cheaper than that.

So Ignore petrol price data as it's absolutely incorrect and they don't seem to be interested in doing anything about it.

I've already logged 2 calls about this with them and they still haven't updated this crappy data.

apple u suck for what u forced on iphone customers

This is the thing that stopped me from getting an iPhone... Pay through the nose AND get locked into a carrier (doesn't matter which carrier just getting locked in is bad enough). Now O2 are proving themselves unworthy to boot...

I'm sure I'm not the only one - come on apple I want to buy an iphone without locks FFS .. don't deal with carriers - look at the grief u're getting re google phone and ATT with FCC ...

I'm sure it would sell more without all these silly arrangements...

Then have carriers offer bundles for people who only want sim only deals... and carriers can choose to provide iphone specific features to attract iphone customers... then handset manufacturers would go back to making handsets for customers that actually use them...

Alas this is too common sense for it to actually happen .... sniff...

Network Solutions breach exposed 500k card accounts

Alert

hmmm what happens to the etailers in this case?

This story has got me thinking... As we are a small e-shop - what happens to the etailer when a card details are exposed in a manner beyond the etailers control?

Is there a liability insurance scheme which can cover this situation?

What if for instance a crooked person inside your servers ISP is diverting card info from your site and since he/she has full root can mask her self .. leaving just the e-tailer to point the finger to???

I think an article on these lines would be warranted - examine all the kinds of ways theft of cc data can be exposed and what liabilities there are etc....

Akasa Integral P2 LAN

Dino

Explanation

I think there is some information lacking re the differecence between NDAS and NAS.

NDAS makes the drive appear as if it is directly attached to the machine and transmits all the raw data it would transfer across a USB port across the Ethernet.

This has severe limitations which have not been pointed out here and I think haven't even been examined or encountered.

The primary limitation for a mixed platform workgroup is that only ONE person can write on the box at a time!. I think this is quite fundamental.

If it is on an all windows network simultaneous writes can be performed but I wonder what it's performance impact would be in this situation.

Page 14 from it's manual:

http://www.akasa.co.uk/pdf/installation_manuals/P2lan_manual_PC.pdf

States:

WARNING:

DO NOT perform disk operations (format, partition and chkdsk) when multiple PCs have the INTEGRAL

LAN drive mounted.

The INTEGRAL LAN device can be formatted, partitioned, chkdsk, aggregated or mirrored when ONLY

one PC is connected.

Multiple-OS sharing:

• The INTEGRAL LAN can be shared by a mixed

of ME/2000/XP and Mac computers

• Multiple computer can have READ ONLY access

simultaneously

• WRITE ACCESS is assigned to one computer at a

time and is passed from one computer to another

Multiple-Write sharing:

• Windows XP/2000 only network environment

• Multiple computer running XP or 2000 can

have READ and WRITE access simultaneously

It does have some interesting capabilities because of this though. It could be used on an exchange server to do certain maintenance tasks that demand a locally attached drive (this would be the only way to do it over the network). Tasks such as Offline defragmentation.

Also what appears to be flexibility of RAID and that it supports native file formats is probably a result of one thing - that it is directly controlled by the host (hence the D in NDAS). It doesn't actually support or use any file system per se - it doesn't care as it doesn't manipulate it. All the circuitry in this box is doing is just transmitting the signals that would normally come through USB through TCP/IP ethernet.

Another thing to consider if considering the RAID aspect - as it is effectively a direct drive setting up two of these devices on the network to form a RAID mirror or RAID 1 does it create twice the data over the network as the host itself is doing the RAID?

These are the things that I would expect to see tested. Can we have another review/test please??
