This is most useful for keeping usernames and passwords in sync without needing to grant access to every single UNIX user. Squid has numerous settings that limit the size of cached objects, the size of client requests and the types of pages to cache. The actual program that handles client requests is a permanently running server process called squid.

What is driving me nuts is that I have two functional squid3 servers running – I copy the very same settings to the new server and squid simply won’t start.

Ubuntu Forums Code of Conduct. All of the instructions in this chapter are written for Squid 2. The access control lists page. Even though it is possible to write a program that does proxy authentication against the UNIX user database, there is another solution—configuring the module to add, delete, and update proxy users whenever a UNIX user is created, removed, or renamed.

If the proxy has already been configured to allow access from anywhere by changing the Deny all restriction to Allow allyou should change it back again to block clients from outside your network.

The Squid module main page. Other programs such as wget or rpm require the username and password to be specified on the command line. Again, Apply Configuravion must be clicked to make any modifications or deletions active.

Webmin comes with a simple program that reads users from a text file in the same format as is used by Apache, and this module allows you to edit users in such a file. Fortunately, Webmin knows which directives each release supports and only allows editing of those that are known to the running version of Squid. The cache options form. If Squid fills up your entire hard drive, problems may occur because other programs are unable to create temporary files or write to logs.


I have the webmin book – but it is from To learn more about the types of ACL available and how to use them, read the next two sections. Because being able to view web pages is extremely useful, a proxy is often set up so that websites can be accessed through it.

Back at the module aquid, click Apply Changes to restart Squid with the newly created restrictions. The most common use of ACLs is blocking connections from clients outside your network. The restriction tables have up and down arrows next to each entry to move them in the list, because their order matters.

This will bring up an editing form identical to the one used for creating the restriction, but with Save and Webmib buttons at the bottom. Squid will compare every request to all defined restrictions in order, stopping when it finds one that matches.

If not, the default setup that allows all ICP packets is fine. I’m running Squid 3.

Every time a cacheable page is requested it is stored in a file, so that when a subsequent request for the same page arrives the file can be read and the data served from it. When it receives a request, Squid first determines which ACLs it matches.

Any help greatly appreciated. Just defining an ACL in the Squid configuration does not actually do anything – it must be applied in some way to have any effect.

After a proxy restriction has been created you can edit it by clicking on the link in the Action column for its row in the table. How digital farming is revolutionizing the future of food. Navigation menu Personal tools English Log in. If your system has more than one hard drive, it makes sense to spread the cache across multiple disks to improve performance.

Thanks to Webminthat is not the case.

After you log in to Webmin as an administrator, you can have Webmin install Squid and then enable the module for you. As the image below shows, a table of ACLs showing their names, types, and matches is configjracion on the left. You can add to and edit entries in the ICP restrictions table in exactly the same squuid as you would for proxy restrictions. ICP requests from other proxies are also checked to see which ACLs they match, and compared against a similar but different list of ICP restrictions to see if they will be allowed or not.


Read on to find out how. Squid can be compiled on all the flavors of Unix sebmin Webmin supports, and works almost identically on all of them. If you run a proxy server that is connected to and accessible from wdbmin Internet, hosts outside your local network should not be allowed to use it. If for some reason you delete all the proxy restrictions, Squid will allow all requests from all clients, which is probably not a good idea.

Because each version of Squid has introduced new configuration directives, this module’s user interface will appear differently depending on the version of Squid that it detects on your system. Because no valid users have been defined yet, configuracon logins will be accepted, which is not particularly useful! The former will save any changes that you make to the action or matching ACLs, while the latter will remove the restriction altogether.

On configuracon other hand, if it really is xon installed you should use the Software Packages module covered on SoftwarePackages to install the squid package from your Linux distribution CD or website. Click the Squid Proxy Server, and you’re ready to start setting it up. The defaults will generally work fine though, with the possible exception of the maximum upload size which is only 1 MB.

Because some web pages change over time or are even dynamically generatedSquid keeps track of the last-modified and expiry dates of web pages so that it can clear data from the cache when it is out of date.
