AXXESS / Afrihost / IS / MWeb DSL slow-to-no international browsing update
For what it’s worth: an alleged SEACOM cable break a few kilometers from Alexandria – eta of 2.5hrs or so… ...

AXXESS / Afrihost / IS / MWeb DSL slow-to-no international browsing
Seems like there is an upstream cable fault (being investigated) that has caused international browsing from South Africa outward to fail. Pings reveal failing terminations on the entry points into continental Europe and the US. IS has reported it as follows, all others are piggy-backing (or just silent on the matter): ...
Stuxnet lessons – and resources
Just a quick grouping of resources relating to Stuxnet resources and analysis after the targeted infections of the frequency converters of the Vaasa, Finland based Vacon (though Vacon publicly denies this) and Iranian company Fararo Paya. The bottomline takeaway – never use default passwords (partical attack vector of the PLCs and SCADAs), and keep systems patched (4 zero-day Windows-based ...
Proxying all Linux Traffic – set web access for Ubuntu behind a proxy
So that it’s documented… I’m using port 8080 as the default port as the likelyhood of your upstream proxy being on 8080 is high – else, typical proxy ports are, of course, 80, 800 (transpartent), 8000, 3128 (squid) To force your server to force web traffic via a proxy, just two quick things to set – in /etc/environment, export one (or two) variables: ...
Search and view gzip’d files
You knew it already – but I keep forgetting – the power of zgrep and zcat both of which behave as their z-less counterparts. So, to search a gzip’d file, you can simply zgrep <term> <filename.gz>, or to cat/view it, zcat <filename.gz> Good to come back to in case of impending forgetfulness… ...
Intel Gigabit Ethernet Card on an old kernel?
For self-reference, mainly: For the Intel Corporation 82574L Gigabit Network Connection on an old kernel that doesn’t have the drivers compiled into it – get the driver and make install it on the platform you’re on, and to be sure (if it doesn’t get done for you) to copy to /lib/modules/2.4.36/kernel/drivers/net/ (your kernel may vary, this is an example only) ...
Your Kindle, PDFs, EPUBs, file and format conversion and you
There are two irritations when it comes to the Kindle. First of those is your collection of PDFs you bought or own that you’d like to read as a ‘book’ on the Kindle (without going through the whole long USER@[free.]kindle.com) email and Whispernet delivery process. The other is the EPUB Sony Book reader format files that you have — but that the Kindle doesn’t interp ...
Firefox: Paste HTML code from one child frame to parent text-box – src stripped
Here’s something fun: use Firefox 3.6.9 to have a set of Javascript code in a child frame append HTML code to a text box in the parent frame, and content of the string is modified: what was <img src="foo.jpg" alt="bar" width="1" height="1" /> becomes <img alt="bar" width="1" height="1" /> which is pretty pointless… ...
MTN Business Data lines crash – down again
Last time, generator maintenance in Johannesburg took everything offline. There was just notification with the subject line “unknown” (referring to the categorisation of the issue) at 14h22: SYMPTOMS EXPERIENCED: Intermittent Degradation in Service SEVERITY: Critical ...
