In this article we are going to add some details to squid in order to allow it to filter based on MAC address and block certain clients from having full access. Alternatively you could reverse the rule and only allow the listed clients to have full access.
I have installed and configured squid in MAC OS X lion. It is working fine (when running./squid it is not returning error) but not sure is it caching the content or not. My target is to setup PROXY CACHE in my local MAC system so that the web documents are returned from the. By using the lightweight Internet Cache Protocol, Squid caches can be arranged in a hierarchy or mesh for additional bandwidth savings. Squid consists of a main server program squid, some optional programs for rewriting requests and performing authentication, and some management and client tools. Take digital handwritten notes for class, work, or fun with Squid on your Android or Chromebook! Markup PDFs, sign documents, & more.
First we are going to assume that you have a working Squid setup if not then there are other articles that will tell you how to get that going, on Redhat or CentOS it is as simple as:
Every now and then you run into a problem with a caching server that causes you to need to clear out the cache. If running Squid, you can look in the /etc/squid/squid.conf configuration file and find a setting in that file called the cachedir, which is a path. For example, we'll use /var/squid/cache in this Continue reading Clear Squid Proxy Caches. Aluminum iMac 24', Mac OS X (10.5.4), Brand New Posted on Sep 3, 2008 6:17 AM. The saving of presets worked perfectly fine with 10.4.x, in fact this is the one.
You are going to want to make the following file in /etc/squid/
In the above file put the MAC addresses of the clients that you want to filter access. Once you have it should look something like:
Now create another file which will be the list of sites that we do not want these clients to be able to access.
For this example we don't want our office staff to be accessing facebook or youtube so the file would look like this:
Now the only things left to do are tell squid conf about these files and then reload or restart squid.
Add the following lines under the other acls
Now do a restart or reload and test it out, you will find that the clients mentioned in /etc/squid/client_macs cannot get to the sites listed in /etc/squid/blocked_sites, exactly as we wanted
Time Control
You might want to control the time of day that certain clients will be filtered using this method. A good solution for this has been written up in the below link.Or you can use the Squid builtin time restrictions. Both are discussed below.
Squid's built-in method:
Alternatively you could use Cron and Template file this is the quick and dirty way to do this, I might write a script in a later post to do this better.
First we need to make a directory for our templates
Now to create our templates
In the day template we are going to want our list of MAC addresses as that is when people will be in the office. In our night template it is going to be an empty file because that is when I.T. will be doing maintenance etc, squid will complain about the empty file but ultimately it does not care.
Now we just need to make our entries in Cron.
We want our day time filter to kick in at 8:30am and our night time filter to kick in at 6:00pm

The Second Life viewer can download a significant amount of data for every location you visit (easily hundreds of MB). In order to save on repeatedly fetching the same data and to speed up the rendering of places you visit frequently the viewer has a local cache that can be up to 10GB in size.
The viewer cache is less than ideal and while it tries very hard to be smart, doesn't get it right nearly as often as it should and can not be shared between different computers / viewers. How often have you teleported home after exploring only to find you have to wait while it downloads again.
A squid proxy cache acts as an intermediary between the viewer and Linden Lab. It fetches the data requested by the viewer and stores it; should it be requested again, it provides the copy it has already downloaded almost instantly.
This makes up for the viewer cache's tendency to forget all the things you would rather it didn't and allows you to run with a much smaller local cache. It can easily be shared by multiple computers in the same household. How to update os x yosemite.
The size of a squid proxy cache is only limited by the amount of disk space you can spare, and it can run quite happily on older / recycled hardware. The software is free open source. Hit to eat mac os.
This guide based on one first published on the Phoenix / Firestorm Wiki and requires some technical ability, It will work with any recent Second Life viewer.
Advantages
- Caches textures, mesh, materials and web content (profiles, search images etc).
- Faster more consistent loading when visiting locations repeatedly.
- Smaller local cache (perhaps even a RAMDisk).
- Reduced bandwidth (useful if you are on a metered service).
- More responsive experience following teleports.
- May enable HTTP texture usage in situations where it has caused problems previously.
- Makes up for viewer cache shortcomings.
- Easily shared by multiple computers, different viewers and other local Second Life users.
- Recycle an older computer and give it a new lease of life!
Caveats
- This solution is entirely unsupported by the Catznip viewer team, while we would be interested to know if you have problems getting it to work, we wont be able to help you.
- The first time a texture / sculpt loads may feel a little slower, it will however load in at a higher resolution.
- Some technical ability is required.

Second Life Squid Proxy for OSX
Use the terminal for all the instructions in this guide. You will need administrator access and your password. This was tested on a Mid 2007 Mac Mini running Mac OS X 10.7.5 'Lion'.
MacPorts
First step is to install MacPorts.
If you already have MacPorts installed, now is a good time to make sure it's all up to date.
Install Squid 2.7
https://tokensgethowslotsemporiumnhdhtofreeoncasinogsn.peatix.com. Newer versions of squid wont work, search MacPorts and see what versions it has:
You will see output similar to this.
In our case we want the first one which is version 2.7, this may take a few moments.
Create store_url_rewrite
We need to create a little script to handle the fetching.
Copy and paste the following :
Then press CTRL+X to exit nano and save the changes.
When back at the console, make the file executable with :
Editing squid.conf
This is a bit of a pain as the config file is very long.
In nano you can press CTRL+_ to go to a specific line number. Line numbers quoted are correct at time of writing.
Go to line 653 and comment out the following two entries.
So it looks like
Scroll down a few lines and to where it says
and add the following line
Go to the refresh pattern section, roughly line 2718 and add 'refresh_pattern /cap/ 259200 20% 302400' so it looks like
Mac Os Versions
Almost done, now go to the very end of the file (press page down a lot) and paste the following
This creates a 32GB cache with the files stored in /opt/local/var/squid/cache/, you can make the cache as large as you like. 10 gnomes in venice mac os.

Start Squid
To start Squid and have it run when the computer starts
Configure the viewer & Final Steps
The following instructions are Catznip specific, for other viewers please refer to their documentation. These steps are required. Once completed relog.
Proxy Settings
In Catznip, open the preferences (CTRL+P), select the 'Setup' tab and press the 'Adjust proxy settings' button. Enter the network address of the machine now running squid, in this case it's named 'MiniMac', If you are running the proxy on the same machine as you use for secondlife it will be 'localhost'. Make sure the port is '3128', and most importantly then at the bottom set 'Other HTTP traffic.' to use the proxy.
Setting the Viewer Cache
You can now reduce the viewer cache. Preferences, 'Advanced tab, move the slider to the desired amount. We do not recommend you set this smaller than 1GB. While here, press the clear cache button.
Enabling HTTP Textures
Mac Os Catalina
Catznip ships with HTTP textures disabled by default due to some long standing issues with some domestic routers.
Enable the 'Developer menu' by pressing CTRL+ALT+Q or via preferences.
From the top menu check Develop > HTTP Texures.
