Ubuntu 16.04 Proxy Server – An Overview 🔎
Ubuntu 16.04 Proxy Server is a software package that comes built-in with Ubuntu 16.04. It is based on the Squid proxy server software and offers many advanced features such as content filtering, logging, and authentication. Ubuntu 16.04 Proxy Server is versatile and can be configured in various ways based on your requirements.
How to Install Ubuntu 16.04 Proxy Server 📥
Before we dive into the installation process, let’s ensure that your Ubuntu 16.04 instance is up to date and has the required packages installed. To update your instance, run the following command:
sudo apt-get update && sudo apt-get upgrade -y
Once your system is up to date, run the following command to install Ubuntu 16.04 Proxy Server:
sudo apt-get install squid
This will install the Squid proxy server software and its dependencies.
How to Configure Ubuntu 16.04 Proxy Server ⚙️
Once you have installed Ubuntu 16.04 Proxy Server, the next step is to configure it to your requirements. The configuration file for Squid is located at /etc/squid/squid.conf. You can edit this file using your favorite text editor.
Here are some of the configuration options you can modify:
1. Port Number 🌐
You can change the listening port for Squid by modifying the http_port option in the configuration file. By default, Squid listens on port 3128. You can change this by modifying the following line:
http_port 3128
For example, to change the listening port to 8080, modify the line as follows:
http_port 8080
2. Access Control 🚪
You can control access to your proxy server by specifying which clients are allowed to connect to it. To do this, modify the following lines:
acl localnet src 192.168.0.0/16http_access allow localnet
In this example, the localnet ACL is defined to include the IP address range 192.168.0.0/16. The http_access option allows clients that match the localnet ACL to connect to the proxy server. You can modify these lines to suit your requirements.
3. Content Filtering 📜
You can use Squid to filter web content based on various criteria such as domain name, URL, and content type. To enable content filtering, you need to define an access list and specify the filtering options. Here’s an example:
acl block_websites dstdomain .example.com
http_access deny block_websites
This example defines an ACL called block_websites that contains the domain name .example.com. The http_access option denies access to clients that match the block_websites ACL. You can modify this example to block or allow access to specific websites.
4. Authentication 🔑
You can require clients to authenticate themselves before accessing the proxy server. Squid supports several authentication methods such as Basic, Digest, and NTLM. To enable authentication, you need to define an auth_param option and specify the authentication method and parameters. Here’s an example:
auth_param basic program /usr/lib/squid/basic_ncsa_auth /etc/squid/passwd
auth_param basic children 5
auth_param basic realm Squid proxy-caching web server
auth_param basic credentialsttl 2 hours
acl auth_users proxy_auth REQUIRED
http_access allow auth_users
This example enables Basic authentication using the /usr/lib/squid/basic_ncsa_auth program and a password file located at /etc/squid/passwd. The auth_users ACL is defined to include clients that authenticate successfully. The http_access option allows clients that match the auth_users ACL to connect to the proxy server. You can modify this example to use a different authentication method or configuration.
