If you live in a hotel for an extended period of time (which can provide significant career benefits – click on this link for details [1]) the issue of food price and availability is going to concern you.
If you are in a decent hotel you will have a fridge in your room that you […]
Recently a user has been asking about SE Linux support in MEPIS [1]. He seems to expect that as the distribution is based on Debian it should have the same SE Linux support as is in Debian.
The problem with derived distributions (which potentially applies to all variants of Debian, Fedora, and RHEL) is that […]
Is it possible to secure Internet banking with SMS?
As secure tokens are too expensive ($10 or more in bulk) and considered to be too difficult to use by many (most?) customers banks have sought out other options. One option that has been implemented by the National Australia Bank and will soon be available from […]
Should you use software or hardware RAID? Many people claim that Hardware RAID is needed for performance (which can be true) but then claim that it’s because of the CPU use of the RAID calculations.
Here is the data logged by the Linux kernel then the RAID-5 and RAID-6 drivers are loaded on a 1GHz […]
In the past I have spent about 18 months living in hotels with a couple of months of breaks in between. I have previously written about it in terms of living in London hotels [1], but I have been asked for more generic advice.

SE Linux has a utility named restorecon to set (or reset) the security context. This is useful for many reasons, corrupted filesystems, users removing files or changing the context in inappropriate ways, and for re-creating files from tar files or backup programs that don’t restore SE Linux contexts. It can also be used to report […]
On Thursday at Secure Con [1] I gave a lecture about SE Linux that went according to plan, and they gave me a nice bottle of Penfolds Shiraz afterwards (thanks to the sponsors).
During my lecture I announced my plan to run the hands-on training session over the net. The idea is that the Debian […]
My SecureCon tutorial went quite badly today. After having network problems and having both the Xen servers crash for no apparent reason I had to give up and give an impromptu lecture.
The original plan had been to use two Xen servers which each had 15 instances and have the delegates go through a training […]
I’m setting up a training environment based on Xen. The configuration will probably be of use to some people so I’m including it below the fold. Please let me know if you have any ideas for improvements.
The interface for the user has the following documentation:
sudo -u root xen-manage create centos|debian [permissive] Create an […]
Is Squid not returning some data you need on a SE Linux system?
The default configuration of the SE Linux policy for Squid only allows it to connect to a small number of ports which are used for web servers. For example ports http (80) and https (443) are labelled as http_port_t which permits serves […]
