blimey that was quick

The cable tester I ordered at around 17.00 yesterday arrived in this morning’s post. And jolly good it is too for such a ridiculously cheap item. As expected, the instructions are amusing but pretty clear for all that. It is easy to use and feels fairly robust, despite the price. Now the results. I am …

blimey that is cheap

David’s comment to my post about my gigabit ethernet upgrade prompted me to look for a cheap LAN tester so that I could check continuity through the RJ45 coupler that had caused me difficulty. It would also be handy to be able to check the box full of old patch cables that I seem to …

PRISM – we had it first

I can exclusively reveal that the UK government had a PRISM database long before those upstarts in the USA. In the late 1970s I worked in the Statistics Division of what was then the UK Civil Service Department. We used a database of Civil Service personnel called PRISM (Personnel Record Information System for Management). I …

slow gigabit ethernet

I have been making some changes to my domestic network of late which I will write about later. However, one of the main changes has been an upgrade from 10/100 switches to gigabit – mainly to improve throughput between my central filestore and desktop machines. For cosmetic reasons (and to keep my wife happy) I …

another good reason not to buy one

Back in November 2011 I wrote about the TP-Link TL-SC3130G IP camera. I had some trouble getting that device to work properly over wifi so I returned it and got my money back. Today, Core Security released an advisory about this device (and several others from TP-Link) about a remotely exploitable vulnerability arising from “hard-coded …

digitalocean do it again

I can’t believe these guys. Not only do I get unlimited traffic on a 1 Gig network (now at three locations – I have a VPS in each of Amsterdam, New York and San Francisco) for peanuts, but they have just given me a $5.00 credit (i.e. one month free for one of the servers). …

using an ssh reverse tunnel to bypass NAT firewalls

There is usually more than one way to solve a problem. Back in October last year I wrote about using OpenVPN to bypass NAT firewalls when access to the firewall configuration was not available. I have also written about using ssh to tunnel out to a tor proxy. What I haven’t previously commented on is …

now that is what an isp should be like

In my post about the astonishing speed of the DigitalOcean network compared to the appalling service I was getting at ThrustVPS, I mentioned that the free bandwidth model didn’t look sustainable in the long run. Indeed, DigitalOcean told me themselves that they would move to a more normal commercial model when they had a better …

what a difference a gig makes

During the new year period when I was having a little local difficulty with thrustVPS, I started looking around for alternative providers. My first port of call was lowendbox. That site lists many VPS providers and is often used by suppliers to advertise “special deals” for short periods. Indeed, I think I intially found thrust …

my top ten

I have been collecting statistics on trivia’s visitors using counterize for some time. The lastest version, which I have been using for about five months now, allows the user to graph, and publish, site statistics in a nice form. I have today created a new page (listed under “longer trivia” on the right) called trivial …

lies, damned lies and VPS traffic

I had an interesting time over the new year period. For some time now I have run a tor node on a VPS at ThrustVPS. I also run my tails mirror on a VPS at the same provider. Their network has always struck me as pretty poor (response times to ssh login is particularly bad, …

password theft

I have mentioned odd postings to bugtraq before. Today, one “gsuberland” added to the canon with a gem about the Netgear WGR614 wireless router. He says in his post that he has been “reverse engineering” this router. Now for most bugtraq posters (and readers) this would mean that he has been disassembling the firmware. But …
