getting squidguard to work!

First, I am using ubuntu 9.0.4. My squid is 2.7stable3. My squidguard is 1.2.

Squid has been working fine for several days, I have a fairly complex set of acls and http_access rules because I am trying to dole out computer time to my kids during the holidays. I am also trying to stop access to certain sites during my "peak time" allocated by my ISP. After working through the obvious errors that a relative newb introduces without meaning to, it is stable, and predictable in behaviour and performance. Suffice to say that I have stripped the squid.conf of unneccesary clutter (comments and unused settings) and have added some structure to it that makes sense to me when going in to tweak it. I do have the original file in two places for referencing when I get into trouble, so can always reinstall and add my tweaks if needed.

Next step was to add squidguard for a deeper level of filtering...

So, I have assiduously followed the instructions here even to the point of copying the errors which reveal themselves on re-reading, e.g. "bash-$ /etc/init.d/squid reload" is missing sudo at the start of the line (it is dereferenced in the preceeding paragraph. After correcting the obvious errors

However, the moment I reload squid or restart squid it fails to load

I actually rebuilt a server because this happened the first time (over a week ago now) thinking that I had damaged some system files (of course I hadn't , but it was worth the practice of installing a new version of the server anyway)

So what can I be doing wrong? The only thing that makes sense is that I am adding the squidguard lines in the wrong place, but after having reviewed the original squid.conf my original placement was correct. So, are there any hidden traps for beginners that aren't mentioned in the article.

Well - I found it, after checking the squidguard log file

wrong type of braces in the definitions of dest rules

I had used parantheses () instead of curly braces {}, which with my eyesight the way it is these days (even with my computer prescription glasses) are so similar to a glance rather than a close inspection, that it totally slipped on by

Caught by the worst of the gotchas for newbs who aren't new to programming (hangs head in shame)

Ah, well, at least if anyone else runs across this there is a solution already (I'd gone looking for the matching braces problem and found the bigger one)

Fabric-Based Computing Enables Optimized Hyperscale Data Centers

Today’s modular x86 servers are compute-centric, designed as a least common denominator to support a wide range of IT workloads. Those generic, virtualized IT workloads have much different resource optimization requirements than hyperscale and cloud applications. They have resulted in a “one size fits all” enterprise IT architecture that is not optimized for a specific set of IT workloads, and especially not emerging hyperscale workloads, such as web applications, big data, and object storage. In this report, you will learn how shifting the focus from traditional compute-centric IT architectures to an innovative disaggregated fabric-based architecture can optimize and scale your data center.

Red Hat White Paper: Using an Open Source Framework to Catch the Bad Guy

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6

Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.
