    • 1 General Information 1.1 Introduction The RMIT Wireless VPN solution provides a secure way to access the RMIT network using up to date Wireless technologies coupled with the security of a Virtual Private Network (VPN). Access is provided to: • Email via either WebEMS for staff or NIMS for students. • File access to Novell’s Home drive (H drive) using the NetStorage web interface. • Access to other RMIT systems as if your PC was directly connected to the RMIT network. The wireless network supports both PC and Macintosh users, other devices like PDA’s will be considered in the future. Note: Novells NetStorage provides a means of access to files using HTTP, HTTPS, XML, and WebDAV protocols, without requiring the installation of the NetWare Client and will work on all computers types connected to the wireless network. 1.2 Virus Protection and Helpdesk Support The Wireless Network is configured as a de-militarised zone within the RMIT network. This means that traffic to and from the network is scanned for viruses, worms and other malicious activity. All RMIT members who connect to the wireless network must take responsibility for the virus protection of their own devices. Please ensure that your PC or Macintosh has the latest in virus protection. Helpdesk support offered for troubleshooting the connection to the wireless network is extremely limited. It is the responsibility of the user to install, configure and troubleshoot all wireless software and computer hardware faults. Although we believe that the underlying technology is simple enough for all users to install and use, ITS cannot guarantee that you will be able to connect your PC to the wireless network. This is due to the fact that ITS has no control over the wireless devices being used on the network including and hardware and software. Staff members can contact the ITS Helpdesk on (03) 9925 8888, or via email helpdesk@rmit.edu.au for limited assistance. 1.3 Health and Safety Please take note of the following: Wireless Networking Guide Page 3
    • • If looking for a power point for your notebook, do not unplug devices such as vending machines and printers. • Do not run your power cord across the floor, where people can trip over it. 1.4 Conditions of Use All use of the Wireless Network implies that you agree to abide by the University’s IT policies and procedures including: 1. To acknowledge that all access is for University study or work purposes only. 2. To not undertake any anti-social activities, including nuisance e-mail, chain letters, and obscene, harassing or unwelcome behaviour. 3. To advise appropriate RMIT IT staff or supervisors of any security issues or breaches. 4. To not share your account with anyone and not to disclose your password to anyone, including RMIT employees. 5. To accept that all actions and usage may be monitored or recorded. 6. To not use University systems to attempt to gain unauthorised access to other systems. 7. To not use University resources for commercial purposes without explicit permission. 8. To not send unsolicited e-mail messages to multiple users, unless explicitly approved by the appropriate University authority. 9. Access to the following sites for personal use is specifically prohibited: • Pornography sites • Streaming video, music, internet radio, online games, chat • Gambling sites. 10. To acknowledge that RMIT's systems and networks are not to be used for any illegal activities, including violation of copyright, hacking and the deliberate spreading of viruses or malicious code. Violations of these rules can result in RMIT disciplinary action, dismissal or in extreme cases referral to appropriate authorities. For further details of RMIT IT policies see: http://www.rmit.edu.au/its/policies Wireless Networking Guide Page 4

    • 6 Appendix A: Troubleshooting 6.1 Additional Help Further help can be obtained by: • Visiting the ITS Frequently Asked Questions (FAQ) website at http://www.rmit.edu.au/its/studentfaqs • Launching the VPN client help via the VPN icon in the System tray. 6.2 Wireless VPN client troubleshooting 6.2.1 “Login Failed” Message If the incorrect details are entered into the VPN client login screen the following message may be seen: Figure 41: Login failed message Actions: • Check the correct NDS username and password are being used. • Ensure that the correct settings are being used in the VPN client. Pay particular attention to the Authentication Options screen and ensure that: o The Group Security radio button is selected. o Both Group ID and Group Password are set to “rmit”. o The Group Password Authentication is set. • The dialup drop box must be left at the default of (none); otherwise the client will attempt to dial one of your connections in the MS-DialUp Networking and will bypass the wireless card. 6.2.2 “Connection has been lost” Message If the connection is cancelled or lost, the following message will be displayed: Figure 42: Connection lost message This may be caused by: • Selecting cancel while the client is connecting. • A disruption in the wireless service has occurred. Wireless Networking Guide Page 26
    • Action: Re-launch the VPN client, entering in your NDS Username and Password then selected Connect (see figure 4). Troubleshooting Disconnections from the Wireless Network 6.3 Mobile Wireless Connectivity As the wireless connection to your laptop uses a secure tunnel, a constant connection must be maintained. To avoid being disconnected from the RMIT wireless network please consider the following: • Minimise movement while logged in to the wireless network or ensure that you do not leave a wireless location. • Moving between non-contiguous wireless areas will cause the wireless connection to be lost eg moving from the Hub to the Student Labs in Building 48, as there is no wireless support across Swanston Street. • Moving out of a wireless location then returning will have the same effect i.e. the wireless network connection will be lost. Action: Re-launch the VPN client, entering in your NDS Username and Password then selected Connect (see figure 4). 6.4 Hibernation Mode Allowing your PC to hibernate while still connected will result in the VPN connection being lost. To reconnect: • Simply relaunch the VPN Client entering in the NDS username and password (figure 4). • In extreme cases, a system reboot may be required. Note: • In some cases a delay of 5-minutes is required before a login can be reattempted. This is because the PC may still be trying to maintain a connection that the VPN client has already disconnect for security reasons. To avoid being disconnected by the hibernation mode: 1. Do not allow the PC to enter hibernation mode - review the energy saving settings with and without mains power. 2. Do not force the laptop into hibernation mode without first: o Closing any applications that may be using the network o Logging out of the VPN network. Action: Re-launch the VPN client, entering in your NDS Username and Password then selected Connect (see figure 4). 6.5 Power Configuration Suggestions Many laptops are configured to conserve power by switching off components or lowering the power when on battery. Wireless cards are usually configurable and should be set so the card operates at full power. Wireless Networking Guide Page 27
