I have just uploaded new SE Linux policy packages for Debian/Unstable which will go into Lenny (provided that the FTP masters approve the new packages in time).
The big change is that there are no longer separate packages for strict and targeted policies. There is now a package named selinux-policy-default which has the features of […]
In May 2002 I had an idea for securing access to GNUPG . What I did was to write SE Linux policy to only permit the gpg program to access the secret key (and other files in ~/.gnupg). This meant that the most trivial ways of stealing the secret key would be prevented. However an […]
The first step is to copy /images/xen/vmlinuz and /images/xen/initrd.img from the Fedora (or RHEL or CentOS) DVD somewhere convenient, I use /boot/OS/ (where OS is the name of the image) but other locations will do.
Now choose a suitable Ethernet MAC address for the interface (see my previous post on how I choose them ).
I just wrote about the system administration issues related to the recent Debian SSL/SSH security flaw . The next thing we need to consider is how we can change things to reduce the incidence of such problems.
The problem we just had was due to the most important part of the entropy supply for the […]
It has recently been announced that Debian had a serious bug in the OpenSSL code , the most visible affect of this is compromising SSH keys – but it can also affect VPN and HTTPS keys. Erich Schubert was one of the first people to point out the true horror of the problem, only 2^15 […]
I believe that the Red Hat process which has Fedora for home users (with a rapid release cycle and new versions of software but support for only about one year) and Enterprise Linux (with a ~18 month release cycle, seven years of support, and not always having the latest versions) gives significant benefits for the […]
Mark Shuttleworth has written an interesting post about Ubuntu release dates . He claims that free software distributions are better able to meet release dates than proprietary OSs because they are not doing upstream development. The evidence that free software distributions generally do a reasonable job of meeting release dates (and Ubuntu does an excellent […]
An issue that causes ongoing discussion is what is the purpose of a Planet installation such as Planet Debian . The discussion usually seems to take the less effective form of what is “appropriate” content for the Planet or what is considered to be “abuse” of the Planet. Of course it’s impossible to get anything […]
Recently a Debian Developer resigned from a position of responsibility in the project by writing a blog post. I won’t name the DD or the position he resigned as I think that there are general issues which need discussion and specific examples will get in the way (everyone who is seriously involved will know who […]
Anthony Towns writes about using an improved version of jigdo to download CD/DVD images . His improvement is basically to pipeline operation for better performance.
Jigdo (the Jigsaw download) is a tool to download a set of files and then use them to create a CD or DVD image . The idea is that most […]
