The book SE Linux by Example has been reviewed on Slashdot. The issue of Perl scripts was raised for discussion. It is of course true that a domain which is permitted to run the Perl interpreter can perform arbitrary system calls – it can therefore do anything that SE Linux permits that domain to do. […] I got the idea for this from Ben Hutchings. A. Copy the list below to your own journal and Bold the actions you are already taking Underline the actions you plan to start taking Italicize the actions that don’t apply to you B. Add one (or more) suggested action(s) of your own C. Leave a […] Erich Schubert comments on the issues relating to getting big changes into Debian. This is something that I had also noticed. I started work on SE Linux in Debian in 2001 and continued it actively until 2003 when I joined Red Hat. Less than a year after I joined Red Hat there was a Fedora […] This morning when walking through a shopping center car park on my way to work a grannie came fairly close to squashing me. She accellerated her Mazda 323 backwards as hard as possible and hit a purple Magna. The back ends of both cars were seriously damaged, and the Mazda (which received the worst damage) […] Creating a simple SE Linux policy module is not difficult. audit(1173571340.836:12855): avc: denied { execute } for pid=5678 comm=”spf-policy.pl” name=”hostname” dev=hda ino=1234 scontext=root:system_r:postfix_master_t:s0 tcontext=system_u:object_r:hostname_exec_t:s0 tclass=file For example I had a server with the above messages in the kernel message log from the spf-policy program (run from Postfix) trying to run the “hostnme” program. So I […] Leon Brooks linked to this article claiming that sound not electricity travels through nerves. When you put a moderate voltage through your body it will cause muscle action (try putting 1000V at low current between fingers of the same hand for safety). The original experiment that suggested that electricity is used involved applying a shock […] Late this afternoon I had a visual migraine while driving. I was driving west and the glare from the sun was making it difficult to see so I didn’t realise that I was having a migraine until I stopped. When I finished my journey and went inside a reasonably dark room I started seeing flashes […] I recently bought a refurbished HP DL385 server at auction. It turns out that it takes SFF (Small Form Factor) disks and has the ability to take 8 hot-swap disks (not bad for a 2U server). The machine supports SAS disks and S-ATA disks as well. So the next thing to do is to buy […] I was reading the brochure about the BMW 530i Touring (which seems to be the BMW name for what is known as a “Station Wagon” in Australia or an “Estate” in Europe). I looked at the brochure on the “Touring” because I am interested in a Station-Wagon – the Sedan version of the 5 series […] This morning there were two or three classes from a local primary school on board my tram taking up all the seats (mostly three children to a seat). So to answer some email and write blog entries I had to sit in a stair-well. Melbourne trams are symmetrical so that they can just change direction […] |
