systemd – a Replacement for init etc

The systemd projecct is an interesting concept for replacing init and related code [1]. There have been a few attempts to replace the old init system, upstart is getting some market share in Linux distributions and Solaris has made some interesting changes too.

But systemd is more radical and offers more benefits. While it’s nice [...]

Upgrading a SE Linux system to Debian/Testing (Squeeze)

Upgrade Requirements

Debian/Squeeze (the next release of Debian) will be released some time later this year. Many people are already upgrading test servers, and development systems and workstations that are used to develop code that will be deployed next year.

Debian SSH and SE Linux

I have just filed Debian bug report #556644 against the version of openssh-server in Debian/Unstable (Squeeze). It has a patch that moves the code to set the SE Linux context for the child process before calling chroot. Without this a chroot environment on a SE Linux system can only work correctly if /proc and /selinux [...]

New Play Machine

Update: Thanks to Sven Joachim and Andrew Pollock for informing me about /etc/init.d/mountoverflowtmp which exists to mount a tmpfs named overflow if /tmp is full at boot time. It appears that the system was not compromised. But regular reinstalls are always a good thing.

On the 24th of August this year I noticed the following [...]

For a long time the use of HTTP cookies [1] for tracking the web browsing habits of users has been well known. But I am not aware of any good solution to the problem. A large part of the problem is the needless use of cookies, it seems that many blog servers use cookies even [...]

Why you should maintain old URLs

Below is a message from the thanks file on my SE Linux play machine [1]:

Hello from San Juan, Puerto Rico! I just found out about this server by reading the SELinux book from O’Reilly. The book is pretty old (2004) and I’m glad to know the URL provided on the book still works! All [...]
