beamer and hyperref on a collision course?
Some of my presentations are written in LaTeX, and more specifically using the beamer document class.

Temporary and permanent solutions follows.

Tell rkhunter to ignore /etc/passwd by inserting EXISTWHITELIST=”/etc/passwd” in your rkhunter configuration file. If you prefer not to make this change to your configuration file, make sure you run rkhunter –propupd with the same PATH as given in /etc/crontab. A command like env -i PATH=/etc:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin rkhunter –propupd should suffice. Thanks to Mr. Torfinn Ingolfsen for […]

It’s meaningless to check the syntax of Apache’s configuration files more than once during the same invocation of the startup script for Apache 2.2.x on FreeBSD, when the specified action is, say restart or graceful. Here’s a small patch.

Something was wrong with the combination of PHP 5.3.5, php-mysql 5.3.5, and MySQL 5.5.8 on FreeBSD 8 earlier this month. Any attempt to run the command php -v resulted in PHP hanging after outputting the “Zend line”. Either kill(1) the process or type C-c to put it out of its misery, but neither action is […]

I upgraded one of my systems to FreeBSD 8.2-PRERELEASE the other day. Next, I upgraded rkhunter to 1.3.8 on the same system. The output of the sockstat command sometimes contains more information than rkhunter is prepared to handle, resulting in different outputs from netstat and sockstat. rkhunter treats this as an infection. Maybe it is. […]
