 ## Introduction
 
-This project allows you to easily set up a Guacamole jump-host for secure remote access.
-
-This modular suite of build and management scripts makes provisioning a secure Guacamole jump server a breeze. It supports TLS reverse proxy (self-signed or Let's Encrypt), Active Directory integration, multi-factor authentication, Quick Connect & History Recording Storage UI enhancements, a custom UI theme creation tool & template (dark themed), auto database backup, email alerts, internal security hardening options, and a fail2ban policy for defence against brute force attacks. The suite also includes code for an enterprise deployment similar to [Amazon's Guacamole Bastion Cluster](http://netcubed-ami.s3-website-us-east-1.amazonaws.com/guaws/v2.3.1/cluster/).

 1. Setup the system hostname & local DNS name (Local DNS must be consistent for TLS proxy).
 2. Select either a local MySQL install or use a pre-existing local or remote MySQL instance.
 3. Pick an authentication extension: DUO, TOTP, LDAP/Active Directory, or none.
 4. Select optional console features: Quick Connect & History Recorded Storage UI integrations.
 5. Select the Guacamole front end: Nginx reverse proxy (HTTP or HTTPS) or use the native Guacamole interface on port 8080.
    - If you opt to install Nginx with self-signed TLS:
-     - New server & client browser certificates are saved to `$HOME/guac-setup/tls-certs/[date-time]`.

 - Exit `1-setup.sh` at the first prompt.
 - All configurable script options are noted at the start of `1-setup.sh` under **Silent setup options**. Re-run the edited setup script after making your changes. (Re-run script locally, do not re-run the automatic install web link). 
 - Certain combinations of the **Silent setup options** will allow for a fully unattended install supporting mass deployment or highly customized docker builds.
 
-**Other useful custom install notes:**
+**Other custom install notes:**
 - **Caution:** Re-running the auto-installer re-downloads the suite of scripts and this will overwrite all your script edits. You must therefore run 1-setup.sh LOCALLY after editing. If any other scripts are edited, their corresponding download links in the 1-setup.sh script must also be commented out.
-- Scripts are **automatically updated with your chosen installation settings at 1st install** to create a matched set for consistent future upgrades or feature additions. (Re-downloading from the auto install link will overwrite these updates.)
+- Upgrade scripts are **automatically customised with your specifc installation settings** for consistent future updates. (Re-downloading from the auto install link after install will overwrite all custom settings as above.)
 - Nginx reverse proxy is configured to default to at least TLS 1.2. For ancient systems, see commented sections of the `/etc/nginx/nginx.conf` file after install.
 - A daily MySQL backup job is automatically configured under the script owner's crontab.

 ## High Availability Deployment
 
-👔 **Did you know that Guacamole can run in a load-balanced high availability farm with layered physical/virtual separation between front end, application, and database layers?**
-
-- **For a separate DATABASE layer:** Use the `install-mysql-backend-only.sh` [here](https://github.com/itiligent/Guacamole-Install/tree/main/guac-enterprise-build) to install a standalone instance of the Guacamole MySQL database.
-- **For a separate APPLICATION layer:** Run 1-setup.sh and point new installations to your separate/remote backend database. Just say **no** to the "Install MySQL locally" option and any other local reverse proxy install options.
-- **For a separate WEB layer:** Use the included Nginx installer scripts to build the basis of a separate TLS front end layer, and then apply your preferred Nginx load balancing technique. There are too many load balancing strategies to list here, but as an example [HA Proxy](https://www.haproxy.org/) generally provides superior session persistence & affinity under load-balanced conditions [compared to Open Source Nginx](https://www.nginx.com/products/nginx/compare-models/).

+
+### How to build all Guacamole client extensions:
+Licensing prevents some extensions being supplied in binary form, therefore these must be built from source. To achieve this, follow the exact order below on a fresh Linux system **WITHOUT JVM INSTALLED**. 
+
+#### 1. Obtain the specific JDK dependency
+Download jdk-8u411-linux-x64.tar.gz from [Oracle](https://www.oracle.com/java/technologies/javase/javase8u211-later-archive-downloads.html) (needs an Oracle sign in, select the Linux x64 compressed archive and copy it to your Linux home dir) A backup of this file is achived [here]( https://1drv.ms/u/s!Asccp3ag4RnQj-dAGYyfqwf-Rf5mTg?e=uRy1DM).
+
+### 2. Install the JDK
+```
+sudo mkdir -p /usr/lib/jvm
+sudo tar zxvf jdk-8u411-linux-x64.tar.gz -C /usr/lib/jvm
+sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.8.0_411/bin/java" 1
+sudo update-alternatives --set java /usr/lib/jvm/jdk1.8.0_411/bin/java
+```
+### 3. Clone Guacamole client source
+```sudo apt update && sudo apt -y install git
+git clone https://github.com/apache/guacamole-client.git
+cd guacamole-client
+git checkout 1.5.5 # or whatever version
+```
+### 4. Install Maven and build all the client binaries (with Radius support)
+```
+sudo apt -y install maven
+mvn clean package -Plgpl-extensions
+```
+Build output should show:

+### 5 Move your new extension to the Guacamole server  
+1. As sudo, copy the new `extension.jar` file (found in `guacamole-client/extensions/guacamole-auth-radius/target/`) to `/etc/guacamole/extensions` on your Guacamole server.
+2. Adjust permissions on the new `extension.jar` file with `sudo chmod 664 /etc/guacamole/extensions/extension.jar`
+3. Restart and continue configuring the new extension as per the Guacmole official documentation [here](https://guacamole.apache.org/doc/gug/).
