I have written a script for Debian named selinux-activate which is included in selinux-basics version 0.3.3+nmu1 (which I have uploaded to Debian/Unstable). The script when run with no parameters will change the GRUB configuration to include selinux=1 on the kernel command-line and enable SE Linux support in the PAM modules for login, gdm, and kdm. [...]
Currently Debian/Lenny contains all packages needed to run SE Linux apart from the policy. The policy package is missing because it needs to sit in unstable for a while before migrating to testing (Lenny), and I keep fixing bugs and uploading new versions.
I have set up my own APT repository for SE Linux packages [...]
SE Linux is almost ready to use in Lenny. Currently I am waiting on the packages libsepol1 version 2.0.30-2, policycoreutils 2.0.49-3, and selinux-policy-default version 0.0.20080702-4 to make their way to testing. The first two should get there soon, the policy will take a little longer as I just made a new upload today (to make [...]
I have just bought a EeePC 701 , I chose the old model because it’s significantly smaller than the 90x series and a bit lighter too and it had Linux pre-loaded. Also it was going cheap, while I am not paying for it I give the same attention to saving my clients’ money as to [...]
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 [...]
