You will see that you are now browsing the internet through the proxy server. By default the Squid proxy server is configured to connect to a local network only, if you are not into the local network of the proxy server, you will see an error saying "The proxy server is refusing connections". If you are getting these kind of errors, then you will need to configure Access Control Lists or ACL into the squid configuration file.
To edit the configuration file run the following command. You can use any editor of your choice, in this tutorial we will be using nano editor.
If you don't have nano editor installed, you can run yum -y install nano command to install nano editor. Example rule allowing access from your local networks. Adapt to list your internal IP networks from where browsing should be allowed acl localnet src Uncomment and adjust the following to add a disk cache directory. To allow a range of IP address to use the Internet through your proxy server.
You can add a new ACL entry. Squid supports CIDR notations. Consider an example, if you want to allow a range of IP address from For changes to take effect you will need to restart your Squid server, use the following command for same. By default Squid only consider very few ports as safe ports and allow connections through them. The ports which are allowed by default are:. The ports which are not listed above will not be accessed through the proxy. For example it you want to allow port to be accessed through the proxy server you can add the following ACL entry for this.
If you want to authenticate the user before they can use your proxy server, you can do it using the basic authentication feature available in Squid proxy. Although Squid supports many kind of authentication but basic authentication is very easy to set up.
First of all you will need to install httpd-tools , which comes with a tool htpasswd which we will use to create an encrypted password file.
Run the following command to install httpd-tools. Now create a new file and provide the ownership to squid daemon so that it can access it. Run the following command for same. We have provided some optional configurations, in case you need them. If you are unable to access your proxy server from outside its network, then create an access control list.
Open Squid Proxy configuration file. Squid proxy also allows you to block specific websites. Create a new file to list blocked websites. In this article, we have looked at how to install and configure Squid Proxy server. We have also looked various additional configuration options. If you wish to allow the IP address to access the web through your new proxy server, you will need to add a new ACL access control list line in the configuration file.
Where XX. XX is the actual client IP address you wish to add. The line should be added at the beginning of the file where the ACLs are defined. It is important to note that if Squid is located outside your local network, you should add the public IP address of the client.
As you may have seen in the configuration file, only certain ports are allowed for connecting. You can add more by editing the configuration file. Where XXX is the actual port you wish to load. Again it is a good idea to leave a comment next to that will describe what the port is going to be used for. You will most probably want your users to authenticate before using the proxy.
For that purpose, you can enable basic HTTP authentication. It is easy and fast to configure. Finally, we will create one last ACL that will help us block unwanted websites.
First, create the file that will store the blacklisted sites. The proceeding dot tells squid to block all references to that sites including www. With the information you just got, you can now add some basic filtering for incoming and outgoing traffic through Squid.
If you wish to go the extra mile, you can even configure squid to block some websites during working hours to prevent distractions.
