Tech Corner

Here you will find a compilation of my networking experiences, completed projects with example configurations and best practices, works in progress, and a wide variety of tidbits of information about networking hardware and products. Among topics covered will be high availability, filtering, encryption, multi-homing, intrusion detection, sniffing, caching, layer 2 thru 5 switching, load balancing, VoIP, hardware/software bugs and caveats etc. At the bottom are a variety of links to other good resources for further information on these topics.

Privacy Management

  • How Spammers harvest your email address – things to do or avoid doing to prevent your email address from receiving all that annoying junk mail.
  • liamtog – a nice tool to add to your website to clog those spambot email harvesters.
  • SpamAssassin – a powerful Spam filter with a Bayesian module as well as a tie into Vipul’s Razor built to run on Unix/Linux with Procmail or with various milter add-on’s for Sendmail. I recently replaced Spambouncer with this configuration and it has been much more successful and accurate. I get 2 or 3 Spams a day that actually make it into my inbox now and no false positives, where I used to get 15 to 20 a day with Spambouncer as well as frequent false positives.
  • Snert’s milter-spamc – a great way to tie SpamAssassin into Sendmail for sitewide configuration
  • Snert’s milter-sender – another milter add-on for Sendmail to check the validity of email sender’s
  • – a powerful set of Procmail recipes for filtering incoming email on a Unix system. Based on 5 years of personal experience, this has been an effective filter. The accuracy of this tool to avoid false positives and negatives increased dramatically with the release of version 1.7 and now 1.8 with the use of the Procmail scoring feature.
  • Norton Personal Firewall – aside from securing your PC out of the box from unwanted hacker probes, it has built in privacy management features to protect your confidential information from being accidentally leaked through your web browser or email.
  • Ad Aware – find and remove those annoying and uninvited spyware programs from your computer.
