Etherpad Lite up 'n' running in 5 minutes

Forever aloneEtherpad Lite is a lightweight version of (probably) the most popular web-based collaborative real-time editor - Etherpad. This great peace of software allows multiple users to edit the same document in real-time. To make collaboration easier, users have built-in chat at their disposal. History playback, infinite undo, easy import and export of documents are some of the cool stuff it has to offer.

Compared to the original, EL has very short system requirements list, which makes it very easy to deploy. Since it's written in server-side JavaScript using Node.js, to make it functional for testing/development purposes you'll need only Node.js, but for everyday/production usage it's recommended that you use a web server (e.g. Apache or Nginx) and MySQL.

Webalizer stats for multiple websites

Samuel L. JacksonWebalizer is a web log analysis software licensed under GPL. It's written in C and it's super fast in processing access log files. Configuring Webalizer is very easy, especially if your Apache web server combines all access logs into one log file, but I noticed that many people have trouble configuring Webalizer for multiple websites (virtualhosts). There are a couple of ways to make this trouble disappear, but I'll explain only one which is, in my opinion, one of the easiest and applicable in most scenarios.

Although I'm using CentOS 6, this tutorial isn't CentOS-specific. So, if you're using another distro you'll notice that there are some differences, but you'll get there in the end.

Fine tuning cPanel autoresponder interval

Y u no answer email?If you enabled autoresponder in your cPanel, then you probably noticed that, by default, the sender gets only one autoreponder message every 8 hours. There is nothing wrong with that. In fact, the purpose of this interval setting is to prevent sending a bunch of emails to the sender who sends more then one email to the user who has enabled autoresponder.

Are your emails being automatically deleted from trash folder on cPanel server?

TrashIf you happen to run Courier IMAP server that comes with cPanel, then you are probably experiencing a rather unpleasant feature . By default, Courier will regularly delete every single email from trash folder that is more than 7 days old.

Considering that most people use IMAP protocol to keep their messages safe and always available on the server, this default option can cause a lot of frustration. Luckily, fixing this issue is rather easy and quick (it takes less than a minute).
