Debian is participating in the Google Summer Of Code (or Winter if you are in the southern hemisphere). It would be good if we could get a SE Linux related project in. If you are interested in doing some SE Linux work (or other security related work) in this regard then please let me know. […] This weekend I went to the Ballarat install-fest, mini-conf, and inaugural meeting of the Ballarat Linux Users’ Group (BLUG). This was the second install-fest, the first one was quite successful so it was decided that there was demand for a second. I suggested that what we should do is get some of the more experience […] A common criticism of fluorescent lights is the inability to use dimmers, as mentioned in Julien Goodwin’s blog. However with some thought at the time the lights are installed this problem can be solved. The first thing to keep in mind is that an infinite number of levels of illumination (analogue scale) is not really […] My Thinkpad has started to run hot recently. If I do anything CPU intensive then it will heat up to >80C and then turn itself off. When idling it seems to stay at about 60C when the ambient temperature is about 24C. It used to not be like this, a couple of years ago I […] I just read an interesting blog post from December 2005 about the environmental impact of bio-fuels. It makes some really good points that should be studied by everyone who is interested in protecting the environment. However this doesn’t mean that bio-fuels are inherently bad, just that some methods of production are bad. The blog claims […] 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.
