Upload Your Observatations

You can go to Google map, here is the link. On the Google map, You can point out your outdoor air quality-related observations. Please be precise when dragging the dot into the map and also indicate the time of observation.

Please report your subjective perception, e.g., is it too polluted, is it too hot, too noisy, you can not breath properly or you have other physical/emotional symptoms from your location (e.g., are you happy, sad, irritated, etc., and why).

Please use the appropriate layers to classify whether your observation is from rural area or from urban area.

In addition, you are welcome to use CITI-SENSE CityAir App to give your perception about air quality in your surroundings.

Vpn appliance vmware

If you install OpenVPN Access Server on a Linux OS that you have installed you may also want to install the VMWare Tools or the open source equivalent so that shut down and restart commands can be issued to the virtual machine through the hypervisor properly. Our appliance already comes with the tools installed that are compatible with ESXi and will listen to ESXi’s shut down and restart commands.

If you install OpenVPN Access Server on a Linux OS that you have installed you may also want to install the VMWare Tools or the open source equivalent so that shut down and restart commands can be issued to the virtual machine through the hypervisor properly. Our appliance already comes with the tools installed that are compatible with ESXi and will listen to ESXi’s shut down and restart commands.

The appliance is by default set to. Since it’s likely that you are not in this timezone you should update the timezone setting to the correct timezone. This is especially vital when you plan on using the Google Authenticator multi-factor authentication system, which relies on a time-based one time password system. The correct time on the server is therefore vital. Additionally we recommend you install the NTP (Network Time Protocol) client program so that the appliance can automatically retrieve the correct time and date from the Internet and keep itself perfectly aligned. The below commands run as a root user will do this.

The installation process will tell you where to find the client web service, which is the web based GUI that you can use to log on and connect to the Access Server, and where to find the admin web service, which is where you can log on as an administrative user and manage the configuration, certificate, users, etcetera, in the web based GUI. Usually the client UI is at the address of your server, for example https://192.168.70.222/. The admin UI is usually at the /admin/ address, for example https://192.168.70.222/admin/. Please note that the web services by default actually run on port TCP 943, so you can visit them at https://192.168.70.222:943/ and https://192.168.70.222:943/ as well. The OpenVPN TCP daemon that runs on TCP port 443 redirects incoming browser requests so that it is slightly easier for users to open the web interface.

Immediately upon logging in the installation wizard of OpenVPN Access Server will start asking you questions. We recommend you use the default settings and just press enter to accept them. You can adjust them at any point later on via the web interface. When you are asked for a license key you can simply press enter to continue installation if you do not have a license key and just want to test the product. If your appliance is deployed in a network where there is no DHCP service running your system will not have a valid IP address assigned. In such a case the installation wizard will fail with error. To resolve this you should set a static IP address on your appliance’s network interface as described in the section below, and then simply log on to the appliance again to restart the wizard.We recommend that you set a static IP address anyways, as this will prevent any surprises if at some point in the future the IP address changes because of the nature of DHCP where addresses are assigned dynamically.

In rare cases the OpenVPN Access Server appliance is deployed on a network where there is no DHCP server to automatically assign the Access Server an IP address. This is a problem that can be resolved by setting a static IP address manually. This is a step we describe a little further down on this page – please continue following the steps.

A series of screenshots has been prepared to guide you through the process. You can either just follow the text below, or click the line to reveal a vpn appliance vmware screenshot. As preparation for deployment you should download the OVA file from our website and save it to your computer. The latest OVA can be downloaded here:

Between the time we have generated the appliance and the time you downloaded and deployed the OVA appliance file, a number of updates for the appliance’s operating system may have been released. To ensure that your operating system is up to date the built-in package manager program can be used to retrieve the updates and install them. To do so on the Ubuntu operating system we use in our appliances use the commands when logged on to the Access Server as a root user:

Now that you are logged on as root user on the console you can use the following steps to set a static IP address on the appliance. This is required if your appliance is deployed on a network where addresses are not dynamically assigned, and is recommend on a network where addresses are dynamically assigned, to ensure that it has no chance of changing in the future and possibly breaking things. Configuration of the network interface on Ubuntu is done with a text file that contains the necessary information. To open this configuration file in a text editor run this command:

Now you can use the root user account to log on to the operating system of the appliance directly. It would of course be very much recommended to change the default unsafe password openvpnas to something a lot more secure if you choose to do this. And of course we recommend that you do not do this, but instead use the sudoer user option described in the previous section instead.
