Debian GNU/Linux 5.0 AKA “Lenny” has just been released .
One of the features that is particularly noteworthy is that Xen has been updated and now works fully and correctly on the 2.6.26 kernel (see the Debian Wiki page about Xen for details ). This may not sound exciting, but I know that a lot [...]
This morning I gave a talk at the Security mini-conf of LCA about the status of SE Linux in Debian. Here is a summary of the issues I covered:
In Lenny (the new release of Debian that will come out in a month or two) SE Linux is working well. Considerably better than [...]
I have just had a need to install packages from Debian-Multimedia.org to correctly play .3gp files from my mobile phone (the stock Mplayer in Debian would not play the sound).
As part of getting this to work in a way that I like I rebuilt some packages so that shared objects would not demand an [...]
Mike writes about his work in using namespaces on Linux . In 2006 I presented a paper titled “Polyinstantiation of directories in an SE Linux system” about this at the SAGE-AU conference .
Newer versions of the code in question has been included in Debian/Lenny. So if you want to use namespaces for a login [...]
The first thing you need to do to get started using the Amazon Elastic Compute Cloud (EC2)  is to install the tools to manage the service. The service is run in a client-server manner. You install the client software on your PC to manage the EC2 services that you use.
There are the AMI [...]
Currently we have a problem with the Debian list server and Gmail. Gmail signs all mail that it sends with both DKIM and DomainKeys (DomainKeys has been obsoleted by DKIM so most mail servers implement only one of the two standards although apart from space there is no reason not to use both). The Debian [...]
In my previous post about DKIM  I forgot to mention one critical item, how to get Postfix to actually talk to the DKIM milter. This wasn’t a bad thing because it turned out that I hadn’t got it right.
I had configured the DKIM milter on the same line as the milters for ClamAV [...]
My Play Machine  was offline for most of the past 48 hours (it’s up again now). I have upgraded the hardware for the Dom0 used to run it so that it now has the ability to run more DomU’s. I can now run at least 5 DomUs while previously I could only run 3. [...]
I previously described the goals for SE Linux development in Lenny and assigned numbers to the levels of support . I have just uploaded a new policy to unstable which I hope to get in Lenny that will solve all the major issues for level 1 of support (default configuration with the unconfined_t domain for [...]
A large part of the disagreement about the way to manage the policy seems to be based on who will be the primary “owner” of the policy on the machine. This isn’t a problem that only applies to SE Linux, the same issue applies for various types of configuration files and scripts throughout the process [...]
