  • home | Policyd – Policyd v2 (codenamed "cluebringer") is a multi-platform policy server for popular MTAs. This policy daemon is designed mostly for large scale mail hosting environments. The main goal is to implement as many spam combating and email compliance features as possible while at the same time maintaining the portability, stability and performance required for mission critical email hosting of today. Most of the ideas and methods implemented in Policyd v2 stem from Policyd v1 as well as the authors' long time involvement in large scale mail hosting industry.
  • Using ALIAS-type DNS records for CNAME functionality on naked domains, and an easier alternative – If you've ever wanted to set up domains using cloud hosting services like Heroku or Windows Azure, you've probably come across a limitation with their platforms in regards to using naked domains (the version without the 'www' part, which is also called zone apex or root domain).

  • Mail server statistics – The statistics are based on completely anonymous information and were performed using randomly chosen IP addresses. When connecting to a mail server defined as an MX in the domain configuration, it can reply in a different number of ways. It may not be online, or may be refusing connections. Also, it is possible that the server does not respond back with a "220" line within the period of time we wait, nor provide a banner that identifies the type of the software running on it, at all times.
  • Setting up backup mail exchange server with sendmail « Building systems that WORK – Setting up backup mail exchange server with sendmail

    Most systems admin is used to setting up the primary mail server, but many of them (like me) are not used to setup a backup mail server in a regular basis. This is my attempt to create a complete document on setting up a backup mail server and testing it for the dooms day. […]

  • Migrate website content using ssh + tar (quick and easy) « my two cents – There are times when you cannot create an intermediate tarball when moving your website due to lack of disk space. There are other times when you wanna be smart

  • MobaXterm-Plugins – – This page contains a few third-party MobaXterm plugins that I packaged myself. MobaXterm is an enhanced terminal for Windows build on top of cygwin. It is self-contained and doesn't require installing or managing a ton of dependencies and things like Cygwin.
  • Mirrorvg without locking the volume group – AIX Health Check – When you run the mirrorvg command, you will (by default) lock the volume group it is run against. This way, you have no way of knowing what the status is of the sync process that occurs after mirrorvg has run the mklvcopy commands for all the logical volumes in the volume group. Especially with very large volume groups, this can be a problem.

    The solution however is easy: Make sure to run the mirrorvg command with the -s option, to prevent it to run the sync. Then, when mirrorvg has completed, run the syncvg yourself with the -P option.

  • Get your Dell Service Tag number via the Linux (or Windows) command-line – Brandon Checketts – When your server is located in a data center far away, it makes it difficult to walk over to the box and read the service tag off of it. Fortunately, the Service Tag is stored somewhere in the system BIOS, and is accessible with the ‘dmidecode’ utility.
  • TCP Traffic Analyzer (Yahoo! Developer Network Blog) – You probably have questions like these about traffic on a TCP (Transmission Control Protocol) server (or client):<br />
    <br />
    * How many connections lasted more (or less) than X milliseconds?<br />
    * How many connections needed more than N attempts to succeed?<br />
    * What is the distribution of connection duration or connection throughput?<br />
    * What is the distribution of connection duration or throughput for connections in which the server or client sent more than N bytes?<br />
    * What specific IP addresses and ports had connections that lasted between 50 and 100 milliseconds long?<br />
    <br />
    You can get answers to these questions (and more) using Yahoo!'s TCP Traffic Analyzer (yconalyzer), available as an open-source project via free download.
