| Titre | Ways to setup Squid proxy server and helpful tips |
| Texte | This blog was written by an independent guest blogger. A squid proxy server has two major functions. First, it is an intermediary proxy. Second, it provides cache services for popular network protocols including HTTP and FTP. The use of proxies and cache services makes up a better internet user experience. Proxies provide added layers of security and cache services that make loading processes faster. Obviously, getting both services from a single provider is highly efficient. What is a Squid proxy server? Squid is a Unix-based proxy server that can do both caching and proxying. It can cache any web content to the user or requestor that is from a closer data storage point. It frequently caches large media files and web pages to reduce bandwidth congestion. Thus it decreases loading periods. Squid supports several caching protocols, such as hypertext caching protocols (HTCP), internet cache protocol (ICP), cache array routing protocol (CARP), and web cache communication protocol (WCCP). It also processes caching requests from Domain Name Server (DNS) lookups and Secure Sockets Layer (SSL). You wouldn’t want to miss enjoying the benefits of Squid proxy servers. Here are some ways to set the server up along with tips to maximize your use out of it. Ways to setup a Squid proxy server Squid proxy servers are usually installed in a separate server from the servers with the original content. The first thing to do is to update your server to install the squid proxy server. Check if the server is running by checking its status in the code, before starting to configure the system. Adding allowable sites In the configuration process, you sift through the sites that are allowable through the intermediary web proxy. These sites are considered as part of your ACL or access control list. These are the only sites that the Squid server will proxy and cache data for. Go through the list of acceptable websites and input in the code. Once all of these are encoded in, restart the proxy and check the status afterward. It’s safe to include an open port in the control list. The open port acts as the passageway for the other sites that were not defined and placed under the list. Blocking websites As much as you can configure the server to include sites to process, you can also block access to several websites. In order to carry out this requirement, create a folder under the access command list that will hold all the restricted sites. Limiting internet access is one of the prominent uses of proxy servers, in general. After listing the blocked or restricted sites, a prompt will appear in the code. Aside from blocked sites, you can also create a list of blocked keywords. Many companies configure their proxies to block access to several social networking sites, such as Facebook, Twitter, and Instagram. Once the list is finalized, make sure to save the file and restart the proxy to confirm. Configuring additional authentication To install an added layer of protection in your Squid proxy, install httpd-tools. This lets you create a password for the proxy. Make sure to assign the proxy server as the file owners. Otherwise, your access will be restricted as well. You can also add a pxuser using htpasswd utility. This calls for a different and much stronger password. Make sure not to forget this username and password. This will be used to authorize all proxy connections later on. Helpful tips to note First of all, every time you change or configure the components of the proxy server, make a copy of the original f |
