braindead mail service
Back in early 2019, I wrote about a problem I was having with mail from my system going to BT based accounts. At the time, BT was rejecting my mail as potential spam. As I wrote at the time, I was pleasantly surprised when the BT postmaster replied positively to my request that they investigate …

laws are made to be broken
We here in England must now limit our social interaction to the “rule of six”. Our dear, delusional, demented, certifiable, mendacious, law breaking Prime Minister says that I cannot meet in my home with more than six people – despite the fact that I can go to the Gym, or a Supermarket, or a Pub, …

encrypting DNS on android
My previous two posts discussed the need for encrypted DNS and then how to do it on a linux desktop. I do not have any Microsoft systems so I have no idea how to approach the problem if you use any form of Windows OS, nor do I have any Apple devices so I can’t …

encrypting DNS with dnsmasq and stubby
In my last post I explained that in order to better protect my privacy I wanted to move all my DNS requests from the existing system of clear text requests to one of encrypted requests. My existing system forwarded DNS requests from my internal dnsmasq caching servers to one of my (four) unbound resolvers and …

encrypting DNS
Any casual reader of trivia will be aware that I care about my privacy and that I go to some lengths to maintain that privacy in the face of concerted attempts by ISPs, corporations, government agencies and others to subvert it. In particular I use personally managed OpenVPN servers at various locations to tunnel my …

zooming in on china
Since my previous post below, I have been reading up on Zoom as a company, its staffing and its worrying security (or rather lack of) track record. When I wrote the initial post I said that “Zoom is a US company funded almost entirely by venture capital. Its servers are US based.”. It appears that …

zooming in on cabinet
On Tuesday of this week, Boris Johnson tweeted a picture of what he called the UK’s “first ever digital Cabinet”. That picture (copy below) shows that the Cabinet meeting was held using Zoom – the sort of video conferencing software which is currently popular with business users forced to work at home during the Covid19 …

beware the zombie apocalypse
Tom Scott is a young educational entertainer who publishes fairly regularly on youtube. Back in mid 2004, whilst still a linguistics student at York, he managed to upset both the Home Office and the Cabinet Office by publishing a Department of Vague Paranoia website spoofing the rather po faced official “Preparing for Emergencies” site. Tom’s …

have I been pwned?
Well, I don’t think so. But for a while I was not entirely sure. Following the move last November of trivia from a VM on UK2’s datacentre in London to our new home on a faster VM on ITLDC’s network I have been making a variety of minor changes and doing some essential housework. One …

TLS certificate checks
My move of trivia to a new VM last December prompted me to look again at my server configuration. In particular I wanted to ensure that I was properly redirecting all HTTP requests to HTTPS and that the ciphers and protocols I support are as up to date and strong as possible. Mozilla offers a …

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 …
