Installing Varnish Cache on a cPanel Server

I’ve recently added Varnish Cache to my server with cPanel installed. Varnish Caching is now installed server-wide. It acts as an invisible intermediary between clients and the server and delivers some major speed improvements, noticeably to Magento and Drupal websites.

The Varnish install script created by Shubham Mathur worked very well but it currently doesn’t consider additional IPs. Also, you’ll need something to amend the $_SERVER['REMOTE_ADDR'] server variable to show the client’s IP address and not the server’s.

Server White Listing for Clients

ConfigServer Firewall has been great at keeping unwanted users at bay on my web servers, but it also causes plenty of problems – notably when the SMTP authentication fails multiple times. This is usually caused by an email account trying to send an email and repeatedly using bad credentials to login. After a short period of time, CSF or cPHulk kicks in and blocks all communication with their website.

Managing this is a pain as there is no way (as far as I can tell) to allow clients to white list themselves when this happens. So, I’ve put up a page on a different server that handles requests for white listing.

Bulk update scripts to PHP 5.4+

I’ve written a shell script to bulk update PHP pages, replacing ereg, eregi with preg_match, ereg_match with preg_match, split with preg_split and changing the $HTTP globals to their modern versions. I haven’t seen this anywhere else, so I’d thought I should post something here.

Using SpamAssassin Headers on cPanel

Once SpamAssassin is enabled, you can easily set an Email Filter to clear out your spam…

Filter: Any Header that matches regex "X-Spam-Score: ([2][1-9]|[3-6][0-9])"
Destination: "spam_holding_account@yourdomain"
Filter: Any Header that matches regex "X-Spam-Score: ([7-9][0-9]|[1-9][0-9]{2,})"
Destination: "Discard"

Unlike the other options shown in the email filtering, this actually does the job without freezing up. Using the score numbers (and not regex) fails when there are no SpamAssassin headers present in an email.

Server provider threats

The owner of my server provider Webtapestry has sent me yet another email telling me how fortunate I am not to be paying more money with them. They use this as a get out clause for any problems with the service. Whenever I complain about an issue to do with any aspect of their service or any financial matters, I get the same gumph…
