and darkness shall be upon the face of the net

image of the wikipedia blackout page

Today, 18 January 2012, parts of the ‘net went deliberately dark in combined opposition to the SOPA (A Bill to:“promote prosperity, creativity, entrepreneurship, and innovation by combating the theft of U.S. property, and for other purposes.” I love the “other purposes” bit.) and PIPA bills currently being considered by the US legislative machinery. These two …

t-mobile resets its policy?

As I have mentioned in other posts here, I run my own mail server on one of my VMs. I do this for a variety of reasons, but the main one is that I like to control my own network destiny. Back in October last year I noticed an interesting change in my mail experience …

tails in a spin

When I first tested running a tails mirror on one of my VMs, the traffic level reported by vnstat ran at around 20-30 GiB per day. I figured I could live with that because it meant that my total monthly traffic would be unlikely to exceed my monthly 1TB allowance. However, when I checked the …

tunnelling X over ssh

OK, yes, I know there are probably already a gazillion web pages on the ‘net explaining exactly how to do this, but I got caught out by a silly gotcha when I tried to do this a couple of days ago, so I thought I’d post a note. Firstly, X is not exactly a secure …

tp-link respond

A couple of weeks ago, I wrote about the problems I had with a TP-Link IP camera. Today I received a comment on that post from a guy called Luke in the TP-Link support team. In that response he apologises for the difficulties I had and promises to investigate further. His response deserves as wide …

do not buy one of these

image of TP-Link IP camera

  Standalone IP cameras have come down in price quite remarkably over the past few years. It is now perfectly possible to get a camera for between £50.00 and £75.00, and this makes them attractive for anyone wanting to set up simple “home surveillance” systems. I bought one recently just to see what I could …

no police here

screenshot of www.police.uk website

The UK Home Office launched a new crime statistics website today at www.police.uk. The site is supposed to show “Local crime and policing information for England and Wales”. I’m not entirely convinced of the merit of the site in the first place (and can see all sorts of potential objections arising in some of the …

phone home

image of etherape capture

Google’s chrome browser first appeared back in 2008, since when many commentators have sung its praises. Apparently it is “blindingly fast” (well, let’s face it firefox can be a tad slow, particularly if loaded down with a swathe of plugins) “clean”, and “simple”. Until recently I had not tried chrome (for some fairly obvious reasons) …

update to autossh – or how ServerAliveInterval makes this unnecessary

I had a couple of comments on my earlier post about autossh which suggested that I should look at alternative mechanisms for keeping my ssh tunnel up. Rob in particular suggested that setting “ServerAliveInterval” should work. Oddly I had tried this in the past whilst trying out various configuration options and I swear it didn’t …

autossh – or how to use tor through a central ssh proxy

Since I first set up a remote tor node on a VPS about this time last year, I have played about with various configurations (and used different providers) but I have now settled on using two high bandwidth servers on different networks. One (at daily.co.uk) allows 750 Gig of traffic per month, the other (a …

scroogle is having a problem

I posted a note about scroogle back in January. Scroogle offered an SSL interface to the google engine, and, moreover, didn’t lumber its users with google cookies and sundry other irritations. Since then, however, google themselves have started to offer an SSL interface and, coincidentally, scroogle seem to have started to have some problems. If …

webDAV in lighttpd on debian

I back up all my critical files to one of my slugs using rsync over ssh (and just because I am really cautious I back that slug up to another NAS). Most of the files I care about are the obvious photos of friends and family. I guess that most people these days will have …

unplugged

My earlier problems with the sheevaplug all seem to have stemmed from the fact that I had installed Lenny to SDHC cards. As I mentioned in my post of 7 March, I burned through two cards before eventually giving up and trying a new installation to USB disk. This seems to have fixed the problem …

plug instability

I’m still having a variety of problems with my sheevaplug. Not least of which is the fact that SDHC cards don’t seem to be the best choice of boot medium. I have had failures with two cards now and some searching of the various on-line fora suggests that I am not alone here. In particular, …

from slug to plug

image of sheevaplug

Well this took rather longer than expected. I intended to write about my latest toy much earlier than this, but several things got in the way – more of which later. About three or four weeks ago I bought myself a new sheevaplug. The plug has been on sale in the US for some time, …

system monitoring with munin

A while back a friend and colleague of mine introduced me to the server monitoring tool called munin which he had installed on one of the servers he maintains. It looked interesting enough for me to stick it on my “to do” list for my VPSs. Having a bunch of relevant stats presented in graphical …
