do not ask me for guest posts or links
For the past four years or so I have been receiving increasingly frequent requests for either guest posts, or links to external sites (or sometimes both). The requests have increased in number ever since I started posting about my use of OpenVPN. Many of these requests want me to point to their commercial VPN site. …

retiring the slugs
I first started using Linksys NSLU2s (aka “slugs”) in early 2008. Back then I considered them quite useful and I even ran webservers and local apt-caches on them. But realistically they are (and even then, were) a tad underpowered. Worse, since Debian on the XScale-IXP42x hasn’t been updated for several years, the slugs are probably …

a bargain VPS
I have been using services from ITLDC for about three years now. I initially picked one of their cheap VMs based in the Netherlands whilst I was expanding my VPN usage, and frankly, I was not expecting much in the way of customer service or assistance for the very low price I paid. After all …

more password stupidity
A recent exchange of email with an old friend gave me cause to revisit on-line password/passphrase generators. I cannot for the life of me imagine why anyone would actually use such a thing, but there are a surprisingly large number out there. On the upside, most of these now seem to use TLS encrypted connections …

add my name to the list
At the tail end of last year, Crispin Robinson and Ian Levy of GCHQ published a co-authored essay on “suggested” ways around the “going dark problem” that strong encryption in messaging poses Agencies such as GCHQ and its (foreign) National equivalents. In that essay, the authors were at pains to state that they were not …

openvpn clients on pfsense
In my 2017 article on using OpenVPN on a SOHO router I said: “In testing, I’ve found that using a standard OpenVPN setup (using UDP as the transport) has only a negligible impact on my network usage – certainly much less than using Tor.” That was true back then but is unfortunately not so true …

one unbound and you are free
I have written about my use of OpenVPN in several posts in the past, most latterly in May 2017 in my note about the Investigatory Powers (IP) Bill. In that post I noted that all the major ISPs would be expected to log all their customers’ internet connectivity and to retain such logs for so …

back to the gym
Having just returned from a family holiday which included too much food and drink and nowhere near enough exercise (well, that’s what holidays are for) I needed to get back to the gym in order to work off some of the excess. My local gym has recently undergone a major refurbishment and equipment upgrade and …

more in the “you couldn’t make it up” dept
The UK Parliamentary petitions site is currently hosting what appears to be one of the most popular it has ever listed. The petition seeks to gain support for revocation of article 50 so that the UK can remain in the EU. Personal politics aside (though in the interests of transparency I should say that I …

postfix sender restrictions – job NOT done
OK, I admit to being dumb. I got another scam email yesterday of the same formulation as the earlier ones (mail From: me@mydomain, To: me@mydomain) attempting to extort bitcoin from me. How? What had I missed this time? Well, this was slightly different. Checking the mail headers (and my logs) showed that the email had …

postfix sender restrictions
I mentioned in my previous post that I had recently received one of those scam emails designed to make the recipient think that their account has been compromised in some way and that, furthermore, that compromise has led to malware being installed which has spied on the user’s supposed porn habits. The email then attempts …

congratulations to BT
I have been running my own mail server now for well over a decade. Whilst the actual physical hardware (or actually VPS system) may have changed once or twice during that time, the underlying software (postfix and dovecot on debian) has not really changed all that much. However, what has changed over the last decade …

always keep the address
I normally post a “happy birthday trivia” message at this time of year. Indeed I have been doing this for 12 years now. Of late my posting has become less frequent which is somewhat odd since I now have much more free time than I had back when I started trivia. But no matter – …

wordpress 5.0 editor error
When I posted yesterday I noticed that there was a new version (5.0) of wordpress available for installation. So I decided to spend a short while today upgrading as I always do when a new software version is released. But I hit a snag – a big one. The new version of wordpress includes a …

well I never
It’s not often that I find myself agreeing with GCHQ, but ex GCHQ Director Robert Hannigan’s recent comments in an interview with the BBC Today programme struck a chord. Hannigan headed GCHQ from April 2014 until his resignation for family reasons last year. Whilst in post he pushed for greater transparency at the SIGINT agency. …

re-encrypting trivia
Back in June 2015 I decided to force all connections to trivia over TLS rather than allow plain unencrypted connections. I decided to do this for the obvious reason that it was (and still is) a “good thing” (TM). In my view, all transactions over the ‘net should be encrypted, preferably using strong cyphers offering …

database failure
In 1909, Franz Kafka wrote the “Inclusion of Private Automobile Firms in the Compulsory Insurance Program” as part of “The Office Writings”. His experience of tortuous bureaucracy in Insurance and elsewhere was later reflected in one of his most famous novels “Der Process” (known in English translation as “The Trial”). Back in October last year …

Merry Christmas 2017
I’m a couple of days late this year. I normally post on Christmas Eve, trivia’s birthday, but hey, I’ve been busy (it goes with the territory at this time of year if you are a grandparent). This year I thought I would depart from my usual topic(s) and post a couple of pictures marking the …

multilingual chat
I use email fairly extensively for my public communication but I use XMPP (with suitable end-to-end encryption) for my private, personal communication. And I use my own XMPP server to facilitate this. But as I have mentioned in previous posts my family and many of my friends insist on using proprietary variants of this open …

geeks rule
Well, sliderule, actually. The ‘net is a truly wondrous space. I can’t recall exactly how I stumbled across the “International Sliderule Museum” but it is such a wonderful resource devoted to a tool which most people under the age of 40 will never have used that I just had to post a link to it. …

a letter to our dear home secretary
Dear Amber So,”real people” don’t care about privacy? All they really want is ease of use and a pretty GUI so that they can chat to all their friends on-line? Only “the enemy” (who is that exactly anyway?) needs encryption? Excuse me for asking, but what have you been smoking? Does the Home Office know …

it is now
Back in January 2011, I posted a brief note about a site hosted at the domain “ismycomputeroff.com“. I have just had occasion to look again at that site and found that the domain is now definitely off. It is parked at sedo and is up for sale at the ludicrous price of 599 euros. Tell …
