DNS Round Robin Configuration using Rsync over SSH

The goal is to add the HostGator server to be an exact mirror of the z.askapache.com domain, then to add that server as a 2nd A record to my DNS zone. That way half the visitors to the size will be taking up resources and bandwidth on the HostGator server instead of mine.

Round Robin A records in DNS are intended to evenly distribute queries between each host of the same name. Using some tricks straight out of a hackers toolbox we can verify if the distribution is taking place. (It is.)

Mirroring an Entire Site using Rsync over SSH

Sometimes there is an urgent need for creating an exact duplicate or “mirror” of a web site on a separate server. This could be needed for creating Round Robin Setups, Load-Balancing, Failovers, or for just plain vanilla backups. In the past I have used a lot of different methods to copy data from one server to another, including creating an archive of the whole directory and then using scp to send the file over, creating an archive and then encrypting it and then sending that file over using ftp, curl, etc., and my persistence at learning new ways to do things has paid off because now I use rsync to keep an exact replica of the entire directory on an external server, without having to use all the CPU and resources of other mirroring methods.

Password Protection Plugin Status

I wanted to address why the update to the AskApache Password Protection plugin didn’t happen pre-2009 as I had hoped.. Mostly due to my job but I thought I could at least fill you in. Oh and this is going to get very boring very fast, unless you’re ready to rumble in the zone.

Serve External Javascript Files locally for Increased Speed

One way I speed up AskApache.com is by downloading external third-party javascript files to host on my own server instead of externally. In addition to the obvious speed boost, this lets you configure the caching and compression settings for the files.

Automated Folder Backup Shell-Script

This simple unix shell script automatically creates backups of a specific folder at regular hourly, nightly, weekly, and monthly intervals. Instead of the usual method for copying directory trees using tar with fifo, pipes, rsync, or NFS methods this script uses cpio which is much much faster and has cool options like saving m/a/c times, symlinks, relative paths, and weird file names.
