These instructions are intended to describe the login process for a computer that has never logged into BeaverNet, or that has not attempted to log in to BeaverNet. If you have tried before and have been unsuccessful, some of the steps here may not occur, as the computer may have retained some information from previous login attempts. If you are having trouble logging in to BeaverNet, you may want to review the instructions below to Delete a BeaverNet configuration. This will allow you to remove any retained information before following these instructions.
Open the System Preferences applet and choose the Network panel.
If wireless networking has been turned off, the Network panel will appear as in the illustration above, and the menu bar in the Finder will look like this:
Click on the Turn Wi-Fi On button to enable wireless networking.
The Network panel will indicate that wireless networking is on, and the menu bar will look like this:
The grey bars indicate that wireless networking is on, but there is no active connection.
Next, click on the Advanced button in the Network panel:
In the Advanced dialog, click on the TCP/IP button and verify that the Configure IPv4 menu is set to Using DHCP. This is required for the Caltech wireless networks. To change the setting, click on the menu and choose Using DHCP, then click OK. If no changes were needed you can click the Cancel button.
To create a BeaverNet configuration, begin by clicking on the wireless networking icon in the menu bar. You should see a list of available wireless networks.
Choose Caltech BeaverNet from the menu.
The login dialog will appear, having blank fields for username and password.
Enter your access.caltech username and password in the appropriate fields. You should uncheck the Remember this network check box unless you are sure you want to store your credentials in this configuration. This is especially important if you are not the sole user of the computer or device.
Next, click on the Join button.
A dialog will appear asking you to verify the certificate used for network encryption. The dialog should indicate win-radius-srv1.ad.caltech.edu as in the illustration below:
You can click on the Continue button to go on with the configuration. If you would like to examine the certificate, click on the Show Certificate button. The certificate should appear as "Thawte Premium Server CA":
Once you have examined the certificate you can click Continue.
Note: You may notice that the previous dialog has disappeared, and you are back at the login dialog. This can easily happen, as the validation dialog has a very short timeout. You can just click on Join again. You'll be presented with the validation dialog, and you can click on Continue.
Next, a dialog will appear requesting that you approve the changes made to the trust settings.
The Name field will have your computer user name filled in. The Password field should be filled in with the password you use on your computer, and not your access.caltech password. Click the Update Settings button.
You should see a busy indication on the screen for a short interval while the network connection is being created.
You can check the connection by clicking on the wireless network icon. A check mark will appear next to Caltech BeaverNet.
To disconnect from BeaverNet, you can navigate to any other wireless network you want to use.
You can also click on the wireless networking icon, and choose Turn Wi-Fi Off.
The wireless networking will indicate that wireless networking has been disabled.
Delete a BeaverNet configuration
To completely remove a BeaverNet configuration open the System Preferences applet and choose the Network panel. You should not be connected to BeaverNet.
Check to see that Wi-Fi is selected in the left side of the dialog. If Wi-Fi is not highlighted, click on it to select it.
Next, click on the Advanced button.
The Wi-Fi button at the top of the window should be highlighted. If it isn't, click on it to highlight it.
You should see a list of networks that the computer has joined. Click on Caltech BeaverNet to highlight it. Now, click on the minus sign ("-") underneath the list of networks. The Caltech BeaverNet item in the list will disappear. You can click Cancel if you decide you don't want to delete the configuration.
Click OK to continue.
Next, in the Network panel, the Revert and Apply buttons will be highlighted, or active.
If you decide not to proceed, you can click the Revert button. Click on Apply to delete the BeaverNet configuration.
Now, a confirmation dialog will appear to confirm that the requested changes are intentional.
The Name field will be filled in with your computer user name. Enter the password you use on your computer and click OK to confirm the change.
Next, you'll need to delete the BeaverNet encryption key from the keychain. To do this, open a Finder window and go to Applications->Utilities->Keychain Access.app.
Double-click on the Keychain Access.app to launch it.
In the Keychain Access window, check the upper left section of the window to be sure that the login keychain item is hightlighted. If it is not selected, click on it to select it.
You should see in the main window a line with a certificate labeled win-radius-srv1.ad.caltech.edu. Click on this line to hightlight it. Once you are sure you have selected the correct certificate, click on the Edit menu and choose Delete. The Delete item will not be highlighted if no entry is selected.
You'll be asked to confirm that you want to delete the certificate.
Once you're sure that the correct certificate has been selected, click on the Delete button. Changes to the Key Chain are immediate so there's nothing more to do. Choose Keychain Access->Quit to exit the Keychain Access applet.
