1. How to troubleshoot wireless access issues

Please follow the troubleshooting steps below if you are having issues with accessing wireless network at CSUDH.


Q1. I have configured GoToros-wpa2 wireless network according to instruction. But I can't see the network in the available wireless network list. What may be wrong?

A. Please check if the wireless adapter in your laptop is turned on. In many laptops you can enable or disable wifi with a switch/button. Please check if your laptop has any wifi button. If it does, make sure it is on.

If the wifi button is on, but you are still not seeing it, please make sure that the wireless adapter is enabled in windows. You can check this article if you can't figure out how to find if your wireless adapter is enabled or not.

Q2. I have configured GoToros-wpa2 but it is not prompting me to enter my username and password. What may be wrong?

A. After you configure the GoToros-wpa2 wireless network and if your laptop successfully connects, you will see a login window or a prompt at the bottom right task bar. If you see the login prompt (specifically in XP), you need to click on it to see the login box. In Vista and windows 7, the login box may appear. If you don't see the prompt or login box or you saw it but missed it, but it is not appearing again, do the following:

  • try to connect to the wireless network manually (vista or windows 7) by clicking on Network and Sharing Center. For XP, try rebooting your machine again.
  • If you still cant see the prompt, open a command prompt box, and type: ipconfig /all. Your wireless adapter should not have any static IP address defined. Make sure that ip address and dns setting is set for DHCP (receive automatically)

Q3. I am connected to the wireless network, and I see the login prompt, but it keep prompting me to enter username and password again and again. What may be wrong?

A. Before you can authenticate to the wireless network, you need to make sure that your account is active and you have reset your password by going to https://dhnet.csudh.edu (for both staff and students). If you haven't done this part, you will not be able to authenticate to the wireless network.

However, after you have done all of that, and if you are not able to authenticate to the wireless network but you can access my.csudh.edu, blackboard etc., please contact helpdesk at x.2500 for further investigation about your account related issue.

Q4. I am connected and authenticated to the wireless network, but when i launch a browser, it is not redirecting me to the Cisco Clean Access web page. What may be wrong?

A. Please check the following:

  • check your dns server setting by opening a command prompt box. Make sure your dns server setting is showing ip address of one of the campus dns server, or
  • Make sure that signed actingX control is enabled or set to prompt in your browsers security setting. Check this article to find how to check if it is enabled or not.
  • Make sure that you have the latest version of Java installed and enabled. To get latest version of java, go to: http://www.java.com
  • Some security software such as Norton Internet Security, Mcaffee firewall may prevent loading activeX controls or jave applets. Please check your computer if you have any such security software installed. If you do, please disable it for the duration of installing Cisco NAC agent.

Q5. Cisco NAC agent fails to install. What may be wrong?

A. Cisco NAC agent also uses activeX controls or Java. Please check the steps above to make sure that activex control is enabled, you have the latest version of java and existence of any security software.

CIsco NAC agent may also give an error message during installation. You can click on OK and it will continue. If it does continue and finishes installation, uninstall the NAC agent and re-install at again.


Q6. I have configured GoToros-wpa2 network, but it is not prompting to enter my credentials. What may be wrong?

A. Please check the troubleshooting section of Apple Airport Client Software Configuration article.

Q7. I got the prompt to enter my credentials. But it is not accepting my username of password. What may be wrong?

A. Please see answer to Q3 above.

Q8. How do I check if I am authenticated, logged in to the wireless network and my computer has an IP address?

A. Click on the wireless icon on the menu bar and choose network preferences. Click on AirPort on the left menu and status information will show up on the right. See picture below.

5. CCA Disclosures

What Cisco Clean Access does:

* Helps prevent disastrous outbreaks of viruses and worms by scanning your computer for certain patch and anti-virus requirements set by the administrator

* Offers an easy way for you to fix your own computer without visiting the help desk

What Cisco Clean Access does NOT do:

* Cisco does not monitor traffic

* Cisco cannot access your usernames and passwords

* Cisco does not block specific applications

* Cisco cannot see what's on your hard drive

Bandwidth is a lot like fossil fuels: it's a limited resource. We have to make sure this resource is available to those who need it.

When viruses and worms hit, they take the network down, and they can crash your computer. The majority of these viruses and worms are avoidable, but only if all computers are updated with the latest Microsoft patches and antivirus updates. So we chose Cisco's software to make sure that every computer coming onto the network has the best possible defenses already on it.

Is it a pain? Sure, especially in the beginning if you haven't ever patched your computer. But if it saves you from losing a term paper and lets the support department focus on improving the network instead of fixing laptops it's probably a fair price to pay.

8. Network Authentication

Network Authentication and Validation

Frequently Asked Questions

Key Terms

Network Access Process: The process of authentication and validation of your computer required for network access.

Authentication: The process of verifying your access to the network by confirming your username and password and associating it with your computer.

Validation: The process of confirming that certain security measures are in place on your computer.

Q: How does the Network Authentication and Validation system work?

A: The new computer security system performs the following functions:

* Require authentication to the network.

* Validate whether the system connecting to the network meets the minimum security standards.

* Quarantines the system until it meets the minimum security standards.

* Provides access to the remediation sites.

* Once the system is validated as "clean," allows access to the network.

Q: Why Are We Introducing this Solution Now?

A: There are over 31 medium or higher rated worms (Blaster, Nachi, Netsky, Sobig) that infected computer systems during the first 6 months of 2004. We did not have a solution that could effectively quarantine systems until proven "clean"; thus, many unprotected systems became infected as soon as they were physically plugged into the network. From investigations on the causes of the problems experienced, it has been determined that the best way to prevent this from happening again is to insure that virus software and OS critical update/patches are current and maintained.

Users who did connect systems that were current with both OS patches and anti-virus software also suffered delays in Internet and other network access due to the excessive traffic caused by the infected machines.

Q: How Does Validation Work?

A: The validation solution will "trap" any Internet browser access and redirect the user to a web page that instructs the user to download and install the validation client known as "Clean Access Agent".

Once launched, the client downloads the validation rules and processes these. If the workstation fails the test, it is allowed Internet access only to the remediation sites for a period of time. Once corrected, full network access is provided and a timer is set for the connection.

The connection remains intact until the timer expires; at that time, the connection is reset and the user must re-validate by launching the client.

Q: What is Clean Access Agent?

A: Clean Access Agent is the client application that can check certain security settings on any Microsoft Windows PC to make sure that the system is up-to-date with required security patches and report this status to a Server. No information about the user or the content of user files is sent to the server. Each user must use Clean Access Agent for his/her Microsoft Windows PC in order to authenticate and use the network.

Q: What Validation Checks are being performed?

A: The following are some examples of validation checks that can be performed:

* Run Nessus scans for known vulnerabilities.

* Check for current release of anti-virus software and current virus definitions.

* Check for current Windows OS Patches for Windows machines.

Q: How Long Do the Validation Checks Take?

A: The checks can take between 15 seconds to a few minutes.

Q: How Does Validation Work for Macintosh Users?

A: Macintosh users must authenticate by logging in via a web page. The only validation check for Macintosh systems is the Nessus scan. There is no client which is downloaded to Macintosh systems. The network connection timer is set for Macintosh systems; however, there is no icon that can be right-clicked to logout and subsequently login again.

Q: How Does Validation Work for Linux Users?

A: Linux users must authenticate by logging in via a web page. The only validation check for Linux systems is the Nessus scan. There is no client which is downloaded to Linux systems. The network connection timer is set for Linux systems; however, there is no icon that can be right-clicked to logout and subsequently login again.

Q: What Remediation is Available?

A: Microsoft Windows Patch Failure. If the user's system fails the check for current critical OS patches, the user is instructed to click on the URL for the Microsoft Windows update site and follow the instructions. Additionally, the user is provided the option to download a program that can assist in configuration of Microsoft Windows Automatic Updates.

A: Anti-Virus Failure. If the user's system fails the check for current anti-virus software, the user is provided a download either for the software itself or for the current engine and virus definition files.

A: Host IDS (Intrusion Detection). If the user's system fails the check for current IDS/IPS host agent, the user is provided a download either for the software itself or for the agent files updates.

1. What is a VPN?

VPN stands for Virtual Private Network. It is a set of technologies that allows you to build secure "virtual" paths between hosts on insecure networks. The particular type of VPN Network Services is deploying is commonly known as a remote access VPN. This acts very much like a classical dialup service, except you are using a data network rather than a voice network to make your "calls". Rather than dialing into a modem on the far end, you are making a connection to a VPN concentrator and creating a secure tunnel from your machine to the concentrator, which is located on the CSUDH network. Thus, everything you send and receive to/from the CSUDH network is encrypted. Additionally, your machine will appear as if it were connected directly to the CSUDH network (i.e. you get a CSUDH IP address).

2. When do I need to use VPN service?

If you have a need to use any of the following campus services from a remote location, you need to use VPN:

* Browse campus-limited web resources

* Use Microsoft Outlook client in MAPI mode for connecting to CSUDH exchange server.

* Remote connection to your office desktop

* Mapping drives to campus servers or workstations for transferring files.

3. When I type my password, is it encrypted, or sent over the network in clear-text?

The password is encrypted using the same strength encryption as the VPN tunnel uses. Your password is never sent in the clear when you use VPN!

4. Can I use any remote control software (such as PCAnywhere or Remote Desktop (RDP) utility in XP) to remote control my on-campus PC via the CSUDH VPN Service?


If you use PCAnywhere then you need to install and configure it on your office PC as well as your home computer.

You can also use Remote Desktop (RDP) utility that comes with XP to remote control your PC. For details instruction about how to setup and use RDP, please Click Here.


RDP (Remote Desktop Protocol) requires that TCP port 3389 be accessible in order to establish a connection. RDP is typically classified as "moderately secure" and is vulnerable to Man-In-The-Middle and Brute Force attacks that would give the attacker full control of your computer. It should not be used if sensitive information is being stored on the computer.

5. Can I use VPN while I am on-campus?

No, it is not necessary to use VPN service while you are on campus. It is intended only where you are at a remote location and need to access resources on campus securely.

6. I have a particular software installed on my office computer and I would like to use it while I am away. Can I use VPN for this purpose?

Yes, VPN is specifically required for this purpose. You need to configure your office PC for remote control either by PCAnywhere or Remote Desktop Utility. After that you need to connect to CSUDH network via VPN and launch your remote control software to connect to your office PC. Please see Question 4 above to find out how to setup remote control software.

7. I have a firewall installed on my remote computer. Will it cause any problem?

If you have a firewall such as Zone Alarm installed in your remote computer, it is advisable to disable the firewall when you use the Cisco VPN client to connect to CSUDH network. Otherwise the firewall software can interfere with the VPN client software. The Cisco VPN client itself becomes a firewall as long it is in use. When your use the Cisco client, all incoming connection to your PC will be disabled which means nobody can access your PC from the outside. Only outside access is enabled from your PC. This is done to protect your PC from outside attack and also to protect out network. If your remote computer is behind a separate firewall and you want to use Cisco VPN client, then you need to open up UDP port 4500 for the host VPN.CSUDH.EDU on your firewall. This port is also applicable to any integrated firewall in your PC such as Zone Alarm.

8. I have only dialup connection to the Internet and no broadband (DSL, Cable etc). How do I connect using VPN?

First of all, you need to establish an Internet connection by dialing to your ISP (such as aol, earthlink etc.)

Then you can launch the VPN client and establish a secure connection to the CSUDH network.

Note: If you are currently dialing to the CSUDH directly, you cannot use the VPN client. It will only work when you dial to any external ISP.

General Client FAQ

1. I am having problems getting my client to work, what should I do?

See the Installation guide on this website. If that fails, call x2500 to reach the Helpdesk.


1. Are there currently any known compatibility issues with Windows XP?

Yes, recently a bug in Windows XP has emerged which can cause installation and/or corruption problems. This is a fundamental problem with XP that cannot be worked around inside the current Cisco VPN client. It is fixed with Windows XP service pack 1. It is recommended that you install Service Pack 1 before installing the VPN client. Here is the announcement from Microsoft:


2. In Windows XP, when I install the client, I get a dialog box warning me that the driver is not signed. What should I do?

It is ok to continue with the installation. Just click ok to continue when prompted.

3. In Windows 95, I get an error about Microsoft DUN (Dial Up Networking) 1.2 not being installed.

This means that you are running a pre-OSR2 release of Windows 95. OSR2 or above is required for the VPN software to work properly. You may be able to update your Windows 95 system with a newer version of DUN to work properly with the VPN software. Please see the following link for more information.


1. Is MacOS 10.2 supported?

Yes, MacOS 10.2 is now supported.


1. I am using Redhat 7.2 or above. I have installed the client, and when I try to use it it says I am connecting to ..., but goes no further.

You probably have ipchains or iptables running. This is firewall software that Linux activates automatically. You will need add the proper "holes" in the filter list to allow the VPN software to operate. A good way to make sure this is your problem is to issue the following commands as root

/etc/init.d/ipchains stop

/etc/init.d/iptables stop

This will temporarily disable the firewall. If your vpn client can connect afterwards, please make the necessary changes in your ipchains/iptables config.
