Too Many Authentication Failures – Filezilla

TFileZilla logorust me, we’ve all been there.

And yes, it is immensely frustrating.

Picture the scene – you’ve been good and decided to use key based SSH for securely transferring files between your servers and local machines.  You’ve disabled password access to shore up security even more.  You’re used to using passwords – but keyfiles are no biggie.


“Too many authentication failures”

Panic can certainly start to set in, particularly as Filezilla continues to try and connect when it’s clearly not going to work no matter how many times it tries!  You’re asking yourself why oh why it would attempt such a futile task.  But really, the only question you want answering is why its not working properly.

And usually, the solution is fairly simple.

Keys saved in Pageant

Pageant, or the PuTTy authentication agent, is a handy key repository used by not only the PuTTy SSH/Bash client but also other third party software – including Filezilla.

You load up your first key, go to Filezilla and all is OK.  For Now.  Maybe.

But you add a few more keys and bang, the sh*t has hit the fan.

What’s Up?

Or more like, what’s down?  And the answer to that question will be access to your server from your IP as you do your best imitation of a brute force attack.  Don’t panic though, there’s a fairly reasonable way around it.

Yes Pageant plays nicely with a few keys.  But Filezilla will try each one in order and any reasonably configured server will only allow a few attempts before it decides you are trying to brute force your way.

Fortunately, the answer is fairly simple…

Unfortunately, it means not using Pageant for Filezilla.

Filezilla Key Configuration

Although when you used Pageant and only had a couple of keys you didn’t have to do this and life seemed so much easier, for server / website admins with more than a few sites to manage, it’s more heartache than it’s worth.

You’ve probably got a site configured currently that looks a bit like this:

Head over to the Logon Type dropdown and you’ll notice a Keyfile option – give that a press:

Your password input box will disappear to be replaced by a key file input box:

Go ahead, click on ‘Browse…’ and select your key file.  Job done.

Next time you try to connect to your server, it’ll only try the appropriate key file preventing any pesky brute force look-a-like ‘attacks’ as you try to login.  Enter your key password and boom, you’re in!

We’re Back!


DPS ComputingWe’re successfully back with you after our recent infrastructure upgrade.  Apologies for the intermittent nature you may have experienced on some services over the past couple of days but we should now be back up to tip-top condition.

If you notice any issues, please let us know in the comments below.

This recent infrastructure upgrade is part of our wider plans for this year, including a relaunch of DPS Computing & further app releases over at DPS Apps so stay tuned to the now supercharged, super speed blog for more details coming soon!


DPS David.

We’re On The Move!


DPS ComputingHello everybody,

Exciting news – we’re upgrading our infrastructure to allow us to cater for increased traffic and content available on DPS Computing.  We have taken this decision to allow us to improve the same great services and content that we currently offer with improved performance and security benefits.  This will allow us to more effectively and efficiently deal with the continually increasing traffic to DPS Computing as well as continuing to add even more content to the lineup!

Unfortunately, as with any move, there will be a little bit of disruption but we promise to keep this to an absolute minimum.

As we’ve outgrown our current server setup, we’re moving onto a brand new, improved and powerful server setup to deliver lightning fast, quality services to you – including the blog.

This also ties in more widely with a new launch of DPS Computing coming soon including a totally re-invented web services brand and the launch of exciting new apps over at DPS Apps, which recently underwent a re-brand itself.

Please bear with us as our scheduled maintenance period commences at 01:00 GMT tomorrow (31/01).  Thanks for your patience and by the time the sun rises we should hopefully be all up and running!

As always, thanks for your continued support and if you do notice anything looking a bit out of place, feel free to get in touch and comment below and we’ll get onto it straight away.

Hang on, it’s going to be worth it!


DPS David.

From April 2017, ALL BT customers will be paying for BT Sport (whether you subscribe or not!).

But I don’t subscribe!?

You do now!  No, seriously, you do!

It doesn’t matter anymore – you’re in.  One way or another, from 2nd April 2017, all BT customers, whether you take phone, broadband or any other BT service will be forced to chip in an extra payment each and every month to fund the ludicrous £1.2bn paid by BT Sport for Champions League football rights for the next few seasons.

But why aren’t they simply increasing the price of BT Sport?

They have.  Lots.

And the fact is, the raw customer data is now showing them that if they increase the cost of BT Sport anymore, they will actually start proportionally losing more customers than is compensated for by the increase in revenue.

So naturally, as any good-for-nothing company then goes and does, they see whether they can pick pocket their other loyal customers to get them to pay over the odds for a service that they neither want nor receive.

Now, I’m a football fan – but no one in this country, football fan or otherwise, can actually justify the ludicrous sums of money that companies like BT are paying for one of the most over priced commodities in the land.

Stop whining!  It’s capitalism / the free market.

I’m a fan of capitalism and the free market as much as the next man, but actually, the assertion that this is capitalism or the free market is completely and utterly factually incorrect.

The price paid for the goods and services in question, i.e. Champions League football for 3 seasons, are actually not worth what is being paid for them.

In business terms – paying this much for this deal would be seen as total and utter business suicide.  Remember, ITV Digital?

The fact is, to fund these kinds of horrific and quite frankly sickening deals, BT Sports subscribers would actually have to be paying 3, 4, 5 maybe even 6 times what they are currently paying.  They could easily, justifiably be paying £100/month or more – and it still probably wouldn’t be enough.

Of course, even the most dedicated football fan isn’t going to do this – after all, everyone has their limits – even if it is their passion.

That’s why everyone has to pay.

It’s hardly a large increase!?

Well, actually 8% is a pretty large increase.  Particularly as the previous years inflation was scraping around 1.0%.

And that’s not all, BT are at the same time withdrawing discounts for existing customers as their deals come to an end leading to up to 50% increase in price for existing customers on special deals.

And, this is in the context of 4 or 5 times inflation increases by BT year after year.  They’re making a complete killing – and it’s at your expense.

They’ve frozen the price of line rental – what more do you want?

That’s nice of them.  After all, they have been hiking it for years – so one years freeze still leaves you massively out of pocket.

And we do have to remember that actually the majority of line rental customers don’t even want the ‘service’.

And the fact that despite, over recent years, the cost to telecoms companies of providing a line has decreased 75%, this hasn’t stopped them hiking the price, well above inflation, year after year.

In fact, between 2010 – 2016 – despite the wholesale cost of providing phone lines to customers decreasing by 21.3%, BT actually chose over the same period to increase the cost of lines to it’s customers by 23.3%.

No ones losing out though?

No, you’re right.  No one’s losing out.  Oh…. except…


Why?  Well for a start, the vulnerable, elderly and poor are now paying a fortune (that they cannot afford) for an average service which in many cases – may literally – be a lifeline.

But if the death of an older relative that can’t contact anybody because their landline was cut off when they couldn’t afford the extortionate bills anymore isn’t enough to convince you then…

Whether we like it or not – when deals like this are signed, people die.

Don’t be stupid…. Football causes deaths?

Nope, not football itself, but deals like this do.

Because guess what – the more we pay to football organisations for TV rights, the more they pay their players and….

The more the players are paid, the less tax they pay!

Remember, footballers are not like us – they only have to pay the amount of tax that they feel they should (which is usually none/very little) rather than the actual amount of tax they owe.

Don’t believe me?  Fortunately for you, you don’t have to:

And the list goes on and on and on….

All this ‘avoided’ / evaded tax means that your local hospitals close, your council tax bill rockets, public services get savaged.  You know the austerity script by now I’m sure.

What should I do?

Tell BT to shove their price rises and football rights where the sun doesn’t shine and move to a provider that isn’t going to rinse you and might actually provide you with semi-decent telecoms service!

Wifi Won’t Reconnect? You Need To Reset Your Network Adapter

OK, I feel like I’ve possibly lost some of you there – but don’t worry, all will become clear.  A common problem that arises with wireless networking (wifi) that many of us now use at home to connect to the Internet is sometimes the connection drops – usually at the most inconvenient time.  Like the time you just clicked the big ‘Pay’ button and you’re wondering if the request made it through in time.

You reconnect and away you go again… or do you?  Well not always.  Sometimes despite seeing the network you want to connect to in your list of available networks it just totally refuses to connect, takes an age before saying the network isn’t available or just down right refuses with some sort of cryptic error message.

You could restart your computer – but you’re halfway through doing something and you really don’t want to lose all your open windows and webpages.  Well fear not, there’s another way – and it’s pretty simple.

Resetting Your Network Adapter

Look for the little networking icon next to your clock in the taskbar.  It could look something like this:


Then click ‘Open Network and Sharing Centre’

In the window that then opens you should notice a menu on the left hand side.  From this menu, you need to click on the ‘Change adapter settings’:

You will then have a list of Network Connections shown to you in a new window – similar to below:

You may have more, less or the same number of connections – that part isn’t important.  The important thing is to select the connection that you’re currently having problems with – most likely, simply called, ‘Wi-Fi’.  Handy, right?

Right click on the connection/adapter that you’re using a click on ‘Disable’:

You should then notice that the network connection/adapter is shown as disabled (ignore the fact that ‘Ethernet’ is pictured below – the process is the same):

Wait a few seconds – to allow the whole ‘disabling network adapter’ process to complete and then right click on the connection again and this time, you’ll see that ‘Disable’ has been replaced with ‘Enable’ – click this:

Congratulations!  You’ve reset your network adapter – which should, the majority of the time, resolve any temporary connection issues you’re experiencing and save you having to restart your computer.

PS.  If you’re not sure which network adapter you’re currently using, there isn’t any harm in disabling them all and re-enabling them one-by-one (or all) – it just takes you more time the first time until you figure out which one it is!
