Ruby on Rails has of this writing released patches for a critical security vulnerability affecting nearly all versions of Rails. It is critical that your Rails applications be updated to one of the following versions:

What is Cloud Block Storage?

Cloud Block Storage provides additional hard drive space for your Private Cloud Hosted Server with just a few clicks. The space is not pre-formatted but rather, it is a raw block device. The simplicity of providing a raw block device on the cloud means that you can mount and format the space on your server however you would like, with whatever filesystem is appropriate for your needs. This does entail a small amount of work getting the space into a usable state which we will address in this article.

Servers do a fantastic job of writing down in log files what is happening right that moment. While going back and reading logs later to determine what happened in the past is helpful, it is also useful to watch logs in real time. Linux provides a command line tool that lets us do just that: tail.

One component of Liquid Web’s Server Secure service is an Apache module called Mod Security (often shortened to just “modsec”). Modsec monitors all incoming HTTP requests for malicious behavior and does not complete requests that meet certain criteria. These criteria are spelled out in what are called “rules” or “rulesets”.

One of the perks of having your own domain is the ability to set up e-mail addresses for it. cPanel makes creating a new e-mail address simple.

Back in 2008, all development stopped on PHP 4. Since that time, no features have been added, no bugs have been fixed, and no security holes have been patched up.

If you ever need to upgrade the hardware on your Windows server with the Plesk interface, Liquid Web’s Windows team is happy to help you through the migration. While it is not the simplest process you will ever be a part of, keeping in communication with our Heroic Support will make things go smoothly.

PHP is an important part of your cPanel server. One aspect of PHP’s configuration that can be overlooked is the PHP handler. The PHP handler is the specific implementation of PHP on your server that interfaces with Apache. On a cPanel server, there are four main PHP Handlers:

Many articles in this knowledge base advise editing configuration files. We usually recommend using your preferred text editor. At Liquid Web, we prefer vim. Vim, or its older sibling vi, are installed by default on nearly every dedicated server that we come across. If you do not yet have a preferred text editor, read on to see if vim might work for you.

One of the best tools you can use when tracking down e-mail problems is mail logs. On Liquid Web’s cPanel servers, we have turned on all of exim’s logging capabilities. Full logging means that there is a lot going on, and trying to decipher the logs can be cryptic at first. Let’s take a look at how they are composed.

Note: this article assumes that you have found the mail transaction you are looking for using exigrep.
