It is quite unfortunate that one only has a finite number of hours to dedicate to learning new things, for inevitably there are things we skim over, or worse yet, don’t even know exist. Today, as I was looking for efficient ways of implementing server push for a project of mine, I came across NodeJS.… Continue reading Setting up NodeJS

As such, I present below, an easy procedure for a daily incremental… Continue reading Scriptless backup with cron
Setting Windows’ Time Service’s Update Frequency
There are some instances when it is desirable to change the default interval between synchronizations by the Windows Time Service (i.e. NTP). For instance, I recently encountered a computer where the clock would run a few seconds fast each day (it was not a battery problem), for a quick fix, it was easy to simply have the… Continue reading Setting Windows’ Time Service’s Update Frequency

I have previously written a bit about using IPTables to limit brute-force attacks. For the past month, that system has been working quite well. The typical attack pattern resembled that in [graph 1, graph2]. A few days ago, however, an attack was implemented which ‘fell under the radar’, so to speak – instead of being… Continue reading Escalating Consequences with IPTables
Upgrading sysklog to rsyslog
As a server setup gets more complex, it is possible that the default syslog (sysklogd) lacks the necessary finely grained filtering that may be desired. Common solutions to this are using syslog-ng or rsyslog. I have opted to go with the latter and found it to, so far, be an excellent replacement. Installing rsyslog Update:… Continue reading Upgrading sysklog to rsyslog
Drupal Oddities
I have recently been trying out a number of content management systems (CMSes) on a server with Apache + FastCGI (PHP) as a backend, and Nginx as a frontend (reverse-proxy). Of these (WordPress, Joomla, MediaWiki, and Drupal) the only one to encounter any difficulties was Drupal (version 7). Installation Issues A number of content management… Continue reading Drupal Oddities
