 Follow the steps below to configure Squid with basic authentication.
 
-1. Set up an HTTP Proxy with Basic Authentication. This setup requires users to provide a username and password. Run the
-   following commands as a superuser:
-
-   ```sh
-   apt-get install apache2-utils -y  # Install htpasswd utility
-   htpasswd -c /usr/local/squid/passwd your_user # Create a user
-   ```
-
-   - You will be prompted to enter and confirm a password for `your_user`.
-
-1. Locate the Squid configuration file:
-   - Run `squid -v` to find the configuration file path. Look for the `--sysconfdir` flag (usually `/etc/squid/squid.conf` on Ubuntu).
-
-1. Find the path to your basic_ncsa_auth program:
-   - On Ubuntu, it is usually located at `/usr/lib/squid/basic_ncsa_auth`.
-
 1. Open the Squid configuration file with your favorite text editor (you might need superuser privileges):
 
    ```sh
-   vim <path to config file>/squid.conf
+   vim /etc/conf/squid.conf
    ```
 
-1. Add or modify the following lines (usually at the top of the file) to configure the proxy settings:

+   # Define an ACL for allowing access from the agent's IP address
+   acl agent_ip src <AGENT_IP_ADDRESS>
 
-1. In the same configuration file, find the line that starts with `http_access deny all` and add the `http_access allow authenticated` line above it. It should look like this:
+   # Allow the agent to connect to NGINX One Console
+   acl mgmt_server dstdomain agent.connect.nginx.com
 
-   ```conf
-   http_access allow authenticated
+   # Allow HTTPS traffic (port 443 is default for HTTPS)

 ## Validate connectivity between NGINX Agent, Squid, and NGINX One Console
 
 To test the connectivity between NGINX Agent, Squid, and NGINX One Console, you can use the `curl` command with the proxy settings.
 
 1. Open a secure connection to your instance using SSH and log in.
 1. Run the following `curl` command to test the connection:
    ```sh
-   curl -x http://proxy.example.com:3128 -U your_user:your_password https://mgmt.example.com/api/v1/agents
+   curl -x http://proxy.example.com:3128 -U your_user:your_password https://agent.connect.nginx.com/api/v1/agents
    ```
 
    - Replace `proxy.example.com:3128` with your Squid proxy address and port.
    - Replace `your_user` and `your_password` with the credentials you set up for Squid in the previous steps.
-   - Replace `mgmt.example.com` with your NGINX One Console address.
 
 To test the configuration from a containerized environment, run the following command from within the container:
 
    ```sh
-   curl -x http://host.docker.internal:3128 -U your_user:your_password https://mgmt.example.com/api/v1/agents
+   curl -x http://host.docker.internal:3128 -U your_user:your_password https://agent.connect.nginx.com/api/v1/agents
    ```
 
    - Replace `your_user` and `your_password` with the credentials you set up for Squid in the previous steps.
-   - Replace `mgmt.example.com` with your NGINX One Console address.
 
 ## Troubleshooting
 
 1. Find the configuration and log files:
 
-   - Run `squid -v`.
-   - Look for the `--sysconfdir` flag (usually `/usr/local/etc/squid/squid.conf` or `/opt/homebrew/etc/squid.conf` on
-      Mac OS, and `/etc/squid/squid.conf` on Ubuntu) to find the configuration file.
-   - Look for the `--prefix` flag to find the log file path (usually `/usr/local/var/logs/squid` or `/opt/homebrew/var/logs/squid`
-      on Mac OS, and `/var/log/squid` on Ubuntu) to find the log files.
-   - Look for the `--localstatedir` flag to find the cache directory path (usually `/usr/local/var/cache/squid` or `/opt/homebrew/var/cache/squid`
-      on Mac OS, and `/var/spool/squid` on Ubuntu) to find the cache directory.
-
+   - Run `squid -v | grep "configure options"`
+   - Configuration directory should look like `--sysconfdir=/etc/squid'`
+   - Log directory should look like `--sysconfdir=/var/log'`
