Squid keeps meta data and especially hot objects cached in RAM, caches DNS lookups, supports non-blocking DNS lookups, and implements negative caching of failed requests. Squid supports SSL, extensive access controls, and full request logging. 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.
Since then it has gone through many changes and has many new features. Internet object caching is a way to store requested Internet objects i. Web browsers can then use the local Squid cache as a proxy HTTP server, reducing access time as well as bandwidth consumption. Harris' Lament says, "All the good ones are taken.
Squid was the code name for initial development, and it stuck. This is best answered by the the Squid Versions page where you can also download the sources. Squid is the result of efforts by numerous individuals from the Internet community. The core team and main contributors list is at WhoWeAre. Many sushi bars also have Squid. If you would like your favorite OS to join the list above, please try to build the latest Squid on it and send any feedback to the squid-dev mailing list.
All of our mailing lists have "-subscribe" and "-unsubscribe" addresses that you must use for subscribe and unsubscribe requests. The IRCache Mesh gives information on our operational mesh of caches. The Squid FAQ uh, you're reading it. Oskar's Squid Users Guide. Authoritative Config Guides are available in the menu on squid-cache.
Squid Programmers Guide. Yeah, its extremely incomplete. I assure you this is the most recent version. Squid is copyrighted by The Squid Software Foundation and contributors. Squid contributors and components change with Squid software. Official Squid artwork distribution terms are detailed elsewhere. Adding new features, enhancing, or fixing Squid behavior usually requires source code modifications.
Several options are generally available to those who need Squid development: Wait for somebody to do it: Waiting is free but may take forever. If you want to use this option, make sure you file a bugzilla report describing the bug or enhancement so that others know what you need. Posting feature requests to a mailing list is often useful because it can generate interest and discussion, but without a bugzilla record, your request may be overlooked or forgotten. Do it yourself: Enhancing Squid and working with other developers can be a very rewarding experience.
However, this option requires understanding and modifying the source code, which is getting better, but it is still very complex, often ugly, and lacking documentation. These obstacles affect the required development effort. In most cases, you would want your changes to be incorporated into the official Squid sources for long-term support. To get the code committed, one needs to cooperate with other developers. It is a good idea to describe the changes you are going to work on before diving into development.
Development-related discussions happen on squid-dev mailing list. Documenting upcoming changes as a bugzilla entry or a wiki feature page helps attract contributors or sponsors. Pay somebody to do it: Many organizations and individuals offer commercial Squid development services.
When selecting the developer, discuss how they plan to integrate the changes with the official Squid sources and consider the company past contributions to the Squid project. Please see the "Can I pay? The best development option depends on many factors. In the early years , these developers were able to work on Squid using their free time, research grants, or similarly broad-scope financial support. Requested features were often added on-demand because many folks could work on them.
Most recent contributions, especially large features, are the result of paid development contracts, reflecting both the maturity of software and the lack of "free" time among active Squid developers. Please see Squid Support Services. Please do not email the Squid Project asking for official recommendations -- the Project itself cannot recommend specific Squid administrators or developers due to various conflicts of interests.
However, if the Project could make official referrals, they would probably form a tiny subset of the listed entries. Besides the Services page, you can post a Request For Proposals to squid-users Squid administration and integration or squid-dev Squid development mailing list. A good RFP contains enough details including your deadlines and Squid versions for the respondents to provide a ballpark cost estimate.
Expect private responses to your RFPs and avoid discussing private arrangements on the public mailing lists. Please do not email RFPs to the Project info alias for the reasons discussed in the previous paragraph. You can also donate money or equipment to the Squid project. It was converted to a Wiki in March The wiki is now the authoritative version. Want to contribute? We always welcome help keeping the Squid FAQ up-to-date. If you would like to help out, please register with this Wiki and type away.
What kind of compiler do I need? What else do I need to compile Squid? How do I cross-compile Squid? How do I apply a patch or a diff? That depends on the version of Squid you have chosen to try. Each version has a page of release bundles. Usually you want the release bundle that is listed as the most current. You must download a source archive file of the form squid-x. We recommend you first try one of our mirror sites for the actually download. They are usually faster. Alternatively, the main Squid WWW site www.
Context diffs are usually available for upgrading to new versions. You must run the configure script yourself before running make. We suggest that you first invoke. Do not compile in features you do not think you will need. If you wish to install somewhere else, see the --prefix option for configure. Squid v3. If you are uncertain about your system's C compiler, The GNU C compiler is widely available and supplied in almost all operating systems.
It is also well tested with Squid. Clang is a popular alternative to gcc, especially on BSD systems. It also generally works quite fine for building Squid. Please note that due to a bug in clang's support for atomic operations, squid doesn't build on clang older than 3. You will need the automake toolset for compiling from Makefiles.
You will need Perl installed on your system. Each feature you choose to enable may also require additional libraries or tools to build. Use the. The autotools manual has some simple documentation for this and other cross-configuration options - in particular what they mean is a very useful detail to know. Additionally, Squid is created using several custom tools which are themselves created during the build process. You need the patch program. You should probably duplicate the entire directory structure before applying the patch.
For example, if you are upgrading from squid Squid-3 patches require the -p0 option. After the patch has been applied, you must rebuild Squid from the very beginning, i. Ideally you should use the patch command which comes with your OS. The most useful is --prefix to install it in a different directory. See the OS specific instructions below for.
You will need to specify some of these options to enable or disable certain features. You may need to upgrade your gcc installation to a more recent version. Check your gcc version with gcc -v If it is earlier than 2. Gcc 2. CentOS You will need the usual build chain yum install -y perl gcc autoconf automake make sudo wget and some extra packages yum install libxml2-devel libcap-devel to bootstrap and build from bzr needs also the packages yum install libtool-ltdl-devel The following. The Linux system layout differs markedly from the Squid defaults. The following. For Debian Jesse 8 , Ubuntu Oneiric Remember these are only defaults.
Altering squid. As always, additional libraries may be required to support the features you want to build. The default package dependencies can be installed using: aptitude build-dep squid This requires only that your sources. Features which are not supported by the distribution package will need investigation to discover the dependency package and install it. The usual one requested is libssl-dev for SSL support.
However, please note that Squid As of Debian Squeeze, or Ubuntu Zesty the libssl1. This is resolved in the Squid-4 packages. Init Script The init. It does not come with Squid directly. The general build instructions should be all you need. However, if you wish to integrate patching of Squid with patching of your other FreeBSD packages, it might be easiest to install Squid from the Ports collection. There are three ports, matching the three packages for the current Squid releases: squid33 - the Squid 3.roamafar.trailblazer.outdoorsy.co/kik-bestpreis-chloroquine-250mg.php

See the New configure options: --enable-winservice Updated configure options: --enable-default-hostsfile Unsupported configure options: --with-large-files: No suitable build environment is available on both Cygwin and MinGW, but --enable-large-files works fine Compiling with Cygwin This section needs re-writing. Is has very little in compiling Squid and much about installation.
In order to compile Squid, you need to have Cygwin fully installed. When that has completed run: squid -z If that succeeds, try: squid -N -D -d1 Squid should start. Check that there are no errors. If everything looks good, try browsing through squid. Now, configure cygrunsrv to run Squid as a service as the chosen username. You may need to check permissions here. The following are the recommended minimal options for Windows: Squid-3 : requires Squid If you wish to install somewhere else, change the --prefix option for configure.
When that has completed run: squid -z If that succeeds, try: squid -N -D -d1 squid should start. Now, to run Squid as a Windows system service, run squid -n , this will create a service named "Squid" with automatic startup. To start it run net start squid from command line prompt or use the Services Administrative Applet. Always check the provided release notes for any version specific detail. In order in compile squid, you need to have a reasonable facsimile of a Unix system installed.
This includes bash , make , sed , emx , various file utilities and a few more. I made a few modifications to the pristine EMX 0. I recommend using the -Y and -N options. Unfortunately, not all of the software is available on a stock Solaris install. It has been fixed in later release of the kerberos library. There are several options available: Upgrading your library to a working version is the recommended best option. This has been fixed in the 3. For 3. This is supposed to be a path to the ar program. If configure cannot find ar on your system, then it substitutes false. This is where the ar command should be.
You need to install SUNWbtool if ar is not there. This package includes programs such as ar , as , and ld. Other Platforms Please let us know of other platforms you have built squid. Whether successful or not. Please check the page of platforms on which Squid is known to compile. If you have a problem not listed above with a solution, mail us at squid-dev what you are trying, your Squid version, and the problems you encounter. Warnings are usually not usually a big concern, and can be common with software designed to operate on multiple platforms.
Squid 3. It should be upgraded to bind 9. Contents How big of a system do I need to run Squid? How big of a system do I need to run Squid? There are no hard-and-fast rules. The most important resource for Squid is physical memory, so put as much in your Squid box as you can. Your processor does not need to be ultra-fast. We recommend buying whatever is economical at the time. Your disk system will be the major bottleneck, so fast disks are important for high-volume caches. Your system disk, and logfile disk can probably be IDE without losing any cache performance.
The ratio of memory-to-disk can be important. From Binary Packages if available for your operating system. Or from Source Code. First you need to check your Squid configuration. If it is silent and immediately gives back the command prompt then your squid. After you've finished editing the configuration file, you can start Squid for the first time.
The procedure depends a little bit on which version you are using. First, you must create the swap directories. Probably the best thing to do is run it from your terminal and watch the debugging output. This greatly simplifies starting Squid and means that you don't need to use RunCache or inittab. At the minimum, you only need to enter the pathname to the Squid executable.
In your syslog messages file, you should see something like this: Sep 23 kitty squid: Squid Parent: child process started That means that process ID is the parent process which monitors the child process pid The child process is the one that does all of the work. The parent process just waits for the child process to exit. If the child process exits unexpectedly, the parent will automatically start another child process. In that case, syslog shows: Sep 23 kitty squid: Squid Parent: child process exited with status 1 Sep 23 kitty squid: Squid Parent: child process started If there is some problem, and Squid can not start, the parent process will give up after a while.
Your syslog will show: Sep 23 kitty squid: Exiting due to repeated, frequent failures When this happens you should check your syslog messages and cache. When you look at a process ps command listing, you'll see two squid processes: ?? Ss R Note that if you accidentally kill the parent process, the child process will not notice.
If you want to run Squid from your termainal and prevent it from backgrounding and spawning a child process, use the -N command line option. A sample squid. Or you can write your own using any normal init. Two that you may find useful are wget and echoping. Also, check the log files, most importantly the access. Useful for testing a configuration file on a non-standard port. If you use this option, then debugging messages up to the specified level will also be written to stderr.
Use this only as a last resort. Obviously very useful for debugging problems. This simply checks whether or not the process is actually running. This will decrease the time required to rebuild the cache, but HTTP requests will not be satisfied during this time. If your cache has mostly child caches which use ICP, this will allow your cache to rebuild faster.
How do I see how Squid works? Check the cache. It logs interesting things as a part of its normal operation and can be boosted to show all the boring details. Install and use the.. Squid is a single process application and can not make use of SMP. If you want to make Squid benefit from a SMP system you will need to run multiple instances of Squid and find a way to distribute your users on the different Squid instances just as if you had multiple Squid boxes. Having two CPUs is indeed nice for running other CPU intensive tasks on the same server as the proxy, such as if you have a lot of logs and need to run various statistics collections during peak hours.
Running Squid on separate drives to that which your OS is running is often a very good idea. Consider to correctly set logbias property for zfs fs which Squid's cache stores. Before you start configuring The best all around advice I can give on Squid is to start simple! Once everything works the way you expect, then start tweaking your way into complexity with a means to track the in effectiveness of each change you make and a known good configuration that you can always go back to when you inevitably fubar the thing! How do I configure Squid without re-compiling it? The squid. Please see the directory where you unpacked the source archive.
The configuration includes but not limited to HTTP port number, the ICP request port number, incoming and outgoing requests, information about firewall access, and various timeout information. There is still a fair bit of config knowledge buried in the old SquidFaq and Guide pages of this wiki. We are endeavoring to pull them into a layout easier to use. Any complex tuning stuff mixing features and specific demos in ConfigExamples and usually linked from the related features or FAQ pages as well.
For Squid 2. From 2. They list all the options each version of Squid can accept in its squid. This minimal configuration does not work with versions earlier than 3. If you are behind a firewall which can't make direct connections to the outside world, you must use a parent cache. Normally Squid tries to be smart and only uses cache peers when it makes sense from a perspective of global hit ratio, and thus you need to tell Squid when it can not go direct and must use a parent proxy even if it knows the request will be a cache miss.
For example, if Squid must connect directly to all servers that end with mydomain. Your internal DNS servers may not be able to lookup external domains.

The first is that squid is not very tolerant to running out of disk space. So in any case make sure to leave some extra room for this, or your cache will enter an endless crash-restart cycle. The second reason is fragmentation note, this won't apply to the COSS object storage engine - when it will be ready : filesystems can only do so much to avoid fragmentation, and in order to be effective they need to have the space to try and optimize file placement.
Get your disk fragmented, and it will most likely be your worst bottleneck, by far offsetting the modest gain you got by having more storage. Let's see an example: you have a 9Gb disk these times they're even hard to find.. First thing, manifacturers often lie about disk capacity the whole Megabyte vs Mebibyte issue , and then the OS needs some space for its accounting structures, so you'll reasonably end up with 8Gib of useable space. If you're getting "disk full" write errors, then you definitely need to decrease your cache size.
Several people on both the fwtk-users and the squid-users mailing asked about using Squid in combination with http-gw from the TIS toolkit. The most elegant way in my opinion is to run an internal Squid caching proxyserver which handles client requests and let this server forward it's requests to the http-gw running on the firewall. Cache hits won't need to be handled by the firewall. In this example Squid runs on the same server as the http-gw, Squid uses and http-gw uses web. The local domain is home.
Below, access. The firewall doesn't need to run large applications like Squid. The internal Squid-server still gives you the benefit of caching. Disadvantages: The internal Squid proxyserver can't and shouldn't work with other parent or neighbor caches. Initial requests are slower because these go through http-gw, http-gw also does reverse lookups. Run a nameserver on the firewall or use an internal nameserver. Security - X-Forwarded-For When a proxy-cache is used, a server does not see the connection coming from the originating client.
Many people like to implement access controls based on the client address. We must note that access controls based on this header are extremely weak and simple to fake. Anyone may hand-enter a request with any IP address whatsoever. Because of the weakness of this header, access controls based on X-Forwarded-For are not used by default. Yes it can, however the way of doing it has changed from earlier versions of squid. Please follow the instructions for the version of squid that you are using.
As a default, no anonymizing is done. NP: Squid must be built with the --enable-http-violations configure option before building. Current squid releases provide a mix of header control directives and capability; Squid 2. For details see the documentation in squid. For example, if you want Squid to connect directly to hotmail.
Sure, there are few things you can do.
What is Internet object caching?
There are three ways to configure browsers to use Squid. The first method involves manually configuring the proxy in each browser. Alternatively, a proxy. Recommended network configuration For best use of the proxy we recommend a multiple-layers approach. The following are the layers we recommend, in order of preference. We are aware that many networks only implement layer 3 and 4 of this design due to administrators familiarity with NAT, confusion about the benefits, and historic problems with the upper two layers. This is particularly useful for mobile users. Proxy auto-configuration PAC aka transparent proxy As a backup to per-machine configuration.
Some systems support PAC file to be explicitly set in the machine-wide environment. Most operating systems support this. Windows is the exception, however the IE settings are used in an equivalent way. A lot of software supports it. Only set once per machine. Nothing beats an explicit manual configuration for it works excitement.
However doing it for each and every piece of software on a machine is quite a hassle. Doing it for a whole network is unrealistic outside of highly paranoid systems. It is mentioned here simply as an option. For completeness sake: the best underlying secure systems back several of these layers up with a complete firewall ban on web traffic. This prevents users and machines bypassing the proxy control points.
Manual Browser Configuration This involves manually specifying the proxy server and port name in each browser. Firefox and Thunderbird manual configuration Both Firefox and Thunderbird are configured in the same way. The options in there are fairly self explanatory. Firefox and Thunderbird support manually specifying the proxy server, automatically downloading a wpad. Thunderbird uses these settings for downloading HTTP images in emails. In both cases if you are manually configuring proxies, make sure you should add relevant statements for your network in the "No Proxy For" boxes.
Click on the Connection tab. For any protocols that your Squid does not support, leave the fields blank. Netscape manual configuration Select Network Preferences from the Options menu. On the Proxies page, click the radio button next to Manual Proxy Configuration and then click on the View button. Lynx and Mosaic manual configuration For Mosaic and Lynx, you can set environment variables before starting the application.
This has the added benefit of causing all Lynx users on a system to access the proxy without making environment variable changes for each user. Click on Okay to accept the setup. Notes: Opera 2. Unfortunately, Opera 2. At the moment I think it has something to do with cookies. Opera will remember the address, so reenabling is easy. Netmanage Internet Chameleon WebSurfer manual configuration Netmanage WebSurfer supports manual proxy configuration and exclusion lists for hosts or domains that should not be fetched via proxy this information is current as of WebSurfer 5.
Select Preferences from the Settings menu. Click on the Proxies tab. On the same configuration window, you'll find a button to bring up the exclusion list dialog box, which will let you enter some hosts or domains that you don't want fetched via proxy. Partially Automatic Configuration This involves the browser being preconfigured with the location of an autoconfiguration script.
Change it down at the bottom. Just select Options from the View menu. Click on the Advanced tab. In the lower left-hand corner, click on the Automatic Configuration button. Then exit MSIE and restart it for the changes to take effect. After reading the 8 steps below, if you don't understand any of the terms or methods mentioned, you probably shouldn't be doing this.
Implementing wpad requires you to fully understand: web server installations and modifications. Domain Name System maintenance etc. Please don't bombard the squid list with web server or DNS questions. See your system administrator, or do some more research on those topics. This is not a recommendation for any product or version. All major browsers out now implementing WPAD. I think WPAD is an excellent feature that will return several hours of life per month.
There are probably many more tricks and tips which hopefully will be detailed here in the future. Things like wpad. I have only focused on the domain name method, to the exclusion of the DHCP method. I think the dns method might be easier for most people. I don't currently, and may never, fully understand wpad and IE5, but this method worked for me. It may work for you. But if you'd rather just have a go The sample provided above is more than adequate to get you going.
No doubt all the other load balancing and backup scripts will be fine also. Store the resultant file in the document root directory of a handy web server as wpad. You can probably even redirect wpad. Insert the following entry into your web server mime.
Maybe in addition to your pac file type, if you've done this before. Test that that all works as per your script and network. There's no point continuing until this works And finally, go back to the setup screen detailed in 5 above, and choose nothing but the Automatically Detect Settings option, turning everything else off.
Best to restart IE5, as you normally do with any Microsoft product And it should all work. Did for me anyway. One final question might be "Which domain name does the client IE5 use for the wpad It starts the search by adding the hostname wpad to current fully-qualified domain name. For instance, a client in a. If it could not locate one, it would remove the bottom-most domain and try again; for instance, it would try wpad. The DNS name method to find wpad.
Another user adds that IE 6. By adding a trailing newline, he is able to make it work with both IE 5. If your script isn't available either because the web server hosting the script is down or your workstation can't reach the web server e. The Netscape browser will just return an error after a timeout after that it tries to find the site 'www.
The point is that your workstations always need to locate the proxy-script.
I created some extra redundancy by hosting the script on two web servers actually Apache web servers on the proxy servers themselves and adding the following records to my primary nameserver: proxy IN A One server mostly caches '. The clients are automatically configured with two nameservers using DHCP. With these you can distribute the load between a number of caching proxies. Where can I find more information about PAC? There are several ways the login can be done with FTP through Squid. It will be overridden by any other available login credentials.
The strongest credentials that override all others are credentials added to the URL itself. Starting with Squid If login is required and none given a regular website login popup box will appear asking for the credentials to be entered. The URL showed up correctly in the browser's "Address:" field, however squid logs show that the trailing slash was being taken off. An example of where this impacted squid if you had a setup where squid would go direct for FTP directory listings but forward a request to a parent for FTP file transfers. This was useful if your upstream proxy was an older version of Squid or another vendors software which displayed directory listings with broken icons and you wanted your own local version of squid to generate proper FTP directory listings instead.
The workaround for this is to add a double slash to any directory listing in which the slash was important, or else upgrade IE to at least 5. The problem will show itself when you first authenticate, you will receive a "Page Cannot Be Displayed" error. However, if you click refresh, the page will be correctly displayed.
This only happens immediately after you authenticate. This is not a Squid error or bug. The problematic file is wininet. Please note that this hotfix is included in the latest security update. Lloyd Parkes notes that the article references another article, KB He says that you must not have the registry entry that KB encourages users to add to their registry. This should trigger IE to handle the authentication in a slightly different manner. Contents Squid Log Files cache.
Squid Log Files The logs are a valuable source of information about Squid workloads and performance. The logs record not only access information, but also system configuration errors and resource consumption e. There are several log file maintained by Squid. Some have to be explicitly activated during compile time, others can safely be deactivated during run-time. There are a few basic points common to all log files.
The time stamps logged into the log files are usually UTC seconds unless stated otherwise. The initial time stamp usually contains a millisecond extension. If you start your Squid using the -s command line option, a copy of certain messages will go into your syslog facilities.
It is a matter of personal preferences to use a separate file for the squid log data. From the area of automatic log file analysis, the cache. You will usually look into this file for automated error reports, when programming Squid, testing new features, or searching for reasons of a perceived misbehavior, etc. Squid Error Messages Error messages come in several forms.
Debug traces are not logged at level 0 or level 1. These levels are reserved for important and critical administrative messages. Affecting all current client traffic being supplied by that Squid instance. Obviously if these occur when starting or configuring a Squid component it must be resolved before you can run Squid. ERROR messages indicate a serious problem which has broken an individual client transaction and may have some effect on other clients indirectly. But has not completely aborted all traffic service.
These can also occur when starting or configuring Squid components. In which case any service actions which that component would have supplied will not happen until it is resolved and Squid reconfigured. NOTE: Some log level 0 error messages inherited from older Squid versions exist without any prioritization tag.
WARNING messages indicate problems which might be causing problems to the client, but Squid is capable of working around automatically. These usually only display at log level 1 and higher.
NOTE: Some log level 1 warning messages inherited from older Squid versions exist without any prioritization tag. Some impossible condition is required to pass the security test. This is commonly seen when testing whether to accept a client request based on some reply detail which will only be available in the future. This is only for problems which are unambiguous. A complete solution to these usually requires fixing the client, which may not be possible. Administrative workarounds extra firewall rules etc can assist Squid in reducing the damage to network performance.
Attack notices may seem rather critical, but occur at level 1 since in all cases Squid also has some workaround it can perform. These are accompanied by hints for better configuration where possible, and an indication of what Squid is going to do instead of the configured action. Previous versions offered a much more limited functionality.
