TLS certificate checks

immuniweb result

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

password generator

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

image of gym workstation screen

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 – …
