      Depends on the number of users that are using the cache.

      It's just for my house, so only a couple people.  However, we tend to be power users. :)

      256M is great, specially for caching hot replies/objects (saves it having to serve it off the disk). Just bare in mind that if your request rate requires more than 256M of memory, squid will increase the memory usage so that it can serve these new requests. Consider that if you dont have a lot of memory.

      So it won't hard limit itself to what I set?  Hmm.  I might have to drop it, then.  I only have 1GB in this machine(can prolly bump it to 1.5), and since I set up squid, I've gone from 15% memory used to 75%.

      Also consider raising the max file size if you plan on downloading larger stuff and want it cached :)

      I was going to do that initially, as I'm barely using any hard drive space with my current install.  Although I only have a 20GB drive.  The 160 I was initially going to use wouldn't work correctly.  I think the mobo didn't support it.

      The reason I went with the default 4 and then 256 was because it mentioned that a lower setting would help more with speed while a higher one would save bandwidth.

      Otherwise for more tuning have a look at http://doc.pfsense.org/index.php/Squid_Package_Tuning - that has some performance tuning and how to cache windows updates etc.

      Also have a look at http://wiki.squid-cache.org/ConfigExamples/DynamicContent/YouTube to give you an idea of what is possible with caching of dynamic content.

      I'll take a look.  Squid is just checking urls, correct?  So if I had the same file served from multiple urls(updates, etc), it wouldn't recognize that, right?

      Also, yesterday I got up to 9.99% hit rate.  :) However, looking at it now, it's down to 4.36% :(

      So I guess I'll tweek the settings and also install the monitoring setup posted earlier.

        Just did the cachemgr.cgi setup.  Man, that's a lot of info.  Is there anyplace that explains what each of those links mean?

        Also, any suggestions for a good SNMP setup?

          Have a look at http://wiki.squid-cache.org/SquidFaq/CacheManager - which provides a lot of info on the statistics that are generated.

          For a good SNMP graph tool check out www.cacti.net and if/once you have that setup download squid template from http://forums.cacti.net/about4142.html

          it will create some nice pretty graphs.

              Sorry been a long week, must be missing something..

              Configured as shown but get a Cache Manager Error.

              connect: (60) Operation timed out

              Not sure which user/password combo its looking for.. but I might not be getting that far that user/pw make a difference

              ran the two CMDs as shown, set the following

              External Cache-Managers set to 192.168.5.1
              cachemgr.conf also set to 192.168.5.1

              You made it sound easy…

                You made it sound easy…

                You should be getting a web page thats says "Cache Manager Interface" and below it a drop down list with the IP address 192.168.5.1 in it.
                The username and password fields you can ignore and just click continue. It should still allow you in. The only difference is that some of the links will not be active for example 'Shut Down the Squid Process'. If you want this links set to active, then in General Settings->Custom options add:

                'cachemgr_passwd none all'

                and click save. You wont have to enter a password. To make it secure have a look at the cachemgr_passwd config option @ http://www.squid-cache.org/Doc/config/cachemgr_passwd/

                  Thanks for the quick reply.

                  I was all around that option reading the squidfaq…

                  retraced my steps, and a reboot

                  Still getting Cache Manager timeout...

                  Running transparent maybe an issue??  I know it causes some limitations in other areas when you use it.

                  Maybe proxy filter service is also having an effect?

                  maybe I need to be hitting 127.0.0.1 instead.  ?? guess its easy enough to try..

                  Do not edit manually !

                  http_port 192.168.5.1:800
                  http_port 127.0.0.1:80 transparent
                  icp_port 0

                    icp_port 0

                    I see you have squid listening on the non default port of 800 - did you add 192.168.5.1:800 to the cachemgr.conf file? Not just 192.168.5.1 - otherwise cachemgr.cgi will try connect to 3128.

                    Shouldn't make a difference whether the proxy is in transparent mode or not.

                        The proxy filter might impact your access to the cache mgr, if you have ip addresses blocked.  Which I did on my production server.

                        But I'm all good now.

                            So I have the cachemgr page working, but one thing concerns me.  On the Store Directory page, it says the following: Accepted object sizes: 0 - (unlimited) bytes

                            However, on the Cache Mgmt page, I have max object size set to 1024.  So why the difference?

                                I am not sure what that reference to GIF89a is? But you should see a page with:

                                Cache server with drop down list of your pfSense's IP address.
                                Input for a Manager name
                                Input for a Password

                                and finally a "Continue" button which will take you to the stats page. What do you see when you click on this button?

                                    Sounds like you dont have your cachemgr.conf file setup correctly and after clicking submit it is timing out.

                                        Please dont hijack another thread but rather start a new one.

                                        Have a look at http://doc.pfsense.org/index.php/SquidGuard_package for instructions.

                                          Did the cachemgr.cgi trick. Working great with squid in transparent mode. Thank you!
