But a large part of the security problems we have […]

A few months ago I gave a lecture about systemd for the Linux Users of Victoria. Here are some of my notes reformatted as a blog post: Scripts in /etc/init.d can still be used, they work the same way as they do under sysvinit for the user. You type the same commands to start and […] Yesterday I installed the wp-spamshield plugin for WordPress [1]. It blocks automated comment spam systems by using JavaScript and cookies, apparently most spammers can’t handle that. Before I installed it I was getting hundreds of spam comments per day even with the block spam by math plugin enabled. Now I’ve had it running for 24 […] type=AVC msg=audit(1403622580.061:96): avc: denied { write } for pid=1331 comm="mysqld_safe" name="/" dev="dm-0" ino=256 scontext=system_u:system_r:mysqld_safe_t:s0 tcontext=system_u:object_r:root_t:s0 tclass=dir type=SYSCALL msg=audit(1403622580.061:96): arch=c000003e syscall=269 success=yes exit=0 a0=ffffffffffffff9c a1=7f5e09bfe798 a2=2 a3=2 items=0 ppid=1109 pid=1331 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm="mysqld_safe" exe="/bin/dash" subj=system_u:system_r:mysqld_safe_t:s0 key=(null) For a long time (probably years) I’ve been seeing messages like […] Portslave is a project that was started in the 90’s to listen to a serial port and launch a PPP or SLIP session after a user has been authenticated, I describe it as a “project” not a “program” because a large part of it’s operation is via a shared object that hooks into pppd, so […] At the end of my talk on Monday about the status of SE Linux [1] I described some of the things that I want to do with SE Linux in Debian (and general SE Linux stuff). Here is a brief summary of some of them: One thing I’ve wanted to do for years is to […] deb http://www.coker.com.au wheezy wordpress I maintain Debian packages of a number of WordPress themes and plugins for my personal use which I am not planning to upload to Debian due to the maintenance and security issues.

Also the capacity of disks is increasing a lot faster than the contiguous IO speed which means that the RAID rebuild time is increasing, for example my first hard disk was […] I’ve just uploaded a new SE Linux policy for Debian/Wheezy. It now works correctly with systemd and Chromium, two significant features that I wanted for Wheezy. Now it turns out that we have until the end of the month for Wheezy updates, so I may get another version of the policy uploaded before then. If […] It’s almost the Wheezy freeze time and I’ve been working frantically to get things working properly.

I would like to get another version […] |
