User and System Requirements
Please note that the settings provided below are specific for the UTS remote labs.
|Operating system||Browser (tested and supported)||Plugins||Screen Resolution|
||1024x768 and above|
For the purpose of using the Remote Labs Rigs, it is assumed that users have access to a workstation with properly working operating system. The current workstation must also have Internet connectivity, preferably with a bandwidth of at least 512kbps downstream.
- Windows 7+
- Mac OS 10.6
Remote Labs have been tested with a number of current web browsers. TLI recommends Firefox. The user is responsible for ensuring that the current browser version is up to date.
- Mozilla Firefox
- Google Chrome
- Internet Explorer
- Apple Safari
Java Runtime Engine
A Java Runtime Engine (JRE) plugin is required to access the Remote Labs through a web browser. Java 7.0 is highly recommended with the latest updates applied. If a user is accessing the rig from his/her home PC and does not have a JRE installed, the user will be automatically asked to install it. Otherwise, the JRE can be found at: http://www.java.com/en/
NOTE: The rig control Java applet first loads when the user is directed to the rig and the user is asked to accept a security warning. If the user does not accept this warning, the rig control applet will not function correctly and the rig cannot be used.
NOTE: In many recent Linux distributions, OpenJDK is packaged as the Java version supported by the distribution package manager. OpenJDK may be successfully used as a Remote Labs compatible JRE.
Depending on the rig type used you may encounter one or more of the following video formats:
- Flash - This requires the Adobe Flash plugin to be installed.
- Motion JPEG - Depending on the browser this may either play within the browser using no plugins (Firefox, Chrome, Safari) or using a Java applet deployed when selecting this format (Internet Explorer).
- JPEG Refresh - This uses JPEG images that are automatically refreshed at a user selected period between 0.25 seconds and 2 seconds and requires no plugins.
If the user is unsure whether any of these plugins are already installed, check the browser settings. On Internet Explorer, go to 'Tools' -> 'Manage Add-ons' and on Mozilla Firefox or Google Chrome type 'about:plugins' in the address bar and press the 'Enter' key.
Often, private networks (such as companies, universities and even home networks) operate through firewalls or proxies. Sahara requires the following ports to be open:
- 3389 (outbound): Remote Desktop Connection
- 7070 (outbound): Video Feed
If very restrictively configured, these may occasionally disallow data coming from the Remote Labs servers to a current browser.
When to Queue
Please check the reservation calendar for availability before queuing. Also, please note that “queuing” for a rig session may result in long wait times due to the high volume of reservations made by other students, academics and Remote Labs technical officers.
As a general note, it is recommended that users utilise the “Queue” option rather than the “Reservation” option as this results in higher efficiency for usage and allocation of rigs to more users.
When to Reserve
Reserving a rig session may be helpful for users who do not have time to queue and wait to use a rig.
Reservation can be made through the reservation calendar. Please be aware that the user must log-in within 10 minutes of your reservation period, otherwise the system will drop the user’s reservation once the timer has expired to allow queuing users to access the rig. The user will not be able to return to the rig without either queuing or making another reservation.
Please be aware of the notification in red located on top of the session screen that states, “Your session will be terminated if you do not use this rig within XXX seconds”.
Also, for users that have created a reservation and do not intend to be use the reservation, please be courteous to others and cancel the reservation so they may use the rig in that time period.
