Known Issues

Following is a list of known issues and bugs, as well as workarounds, that you may experience while using a CLICC desktop or laptop. Most issues will be addressed on a quarterly basis. Urgent issues are dealt with as staff resources permit.

 

Summer 2014

  • Trouble Launching Software Shortcut (Java Security Settings): CLICC's Software Shortcut runs through Java. Therefore, your system's Java security settings can affect how the shortcut runs. Because CLICC computers are updated quarterly, the Java version installed on our computers might become out of date and stop working with the Software Shortcut. We recommend you take the following steps when having trouble with the Software Shortcut:
  1. Use Firefox: Firefox is the default browser for all CLICC computers. We recommend always trying Firefox first for online services.
  2. Ensure Java is Up-to-Date: You can download and install the latest version of Java on CLICC laptops. The username is "cliccuser" and there is no password (i.e. leave the password field blank). Note that when you restart the laptop, any changes to the system will be undone and Java will roll back. You do not need to restart to update Java on a per-session basis.
  3. Add the Software Shorcut URL to Java Site Exceptions List: Open Java preferences in Control Panel for Windows or System Preferences for Mac. Click the Security tab > Edit Site List. Add the URL https://sw-shortcut.library.ucla.edu.
  4. Lower Java Security Settings: For best compatibility on CLICC laptops, we recommend lowering Java security settings to the lowest possible security level. This is not a good security practice and we don't endorse doing this on your personal machines. Follow these steps to check the Java security settings: Open Java preferences in Control Panel for Windows or System Preferences for Mac. Click the Security tab and check "Enable Java content in the browser." Change the security slider level to "Medium." Click the Advanced tab and check the following settings: Shortcut Creation = Always allow; JNLP File/MIME Association = Always allow, Application Installation = Install if hinted; Secure Execution Environment = Allow user to grant permissions & Allow user to accept JNLP & Don't prompt for client certificate selection (Leave others unchecked); Mixed code = Disable verification; Perform certificate revocation checks = Do not check; Advanced Security Settings = Check all EXCEPT Enable blacklist revocation check.

Spring 2014

  • Connecting to Eduroam wireless network prompts for security certificate update: Campus wireless has updated the Eduroam security certificate due to the internet-wide Open SSL "Heartbleed" bug. As a result of the change, users of CLICC laptops will be asked to update the Eduroam certificate upon joining the wireless network on both Windows and Mac sides. Laptop users have administrative rights to install/update the certificate when prompted. The username is "cliccuser" and the password is blank (i.e. no password).

Permanent Issues: Not Bugs, But Be Advised

  • Playing UCLA Library Digital Audio Reserves (RealAudio files) in web browsers: Content will not play directly in the web browser. Be advised that these music links are actually .smil files, not web content, that are supposed to be downloaded and streamed in the standalone RealPlayer application. This is similar to downloading a .docx file and opening in Word. If you clicked a .docx link in a web browser you would not expect the Word document to display in the browser itself. In most cases the standalone RealPlayer application will launch automatically, but in some browsers you may need to manually click the downloaded .smil file.

    Also note that this audio is streaming content and you will sometimes need to wait for audio to load. You may experience typical streaming issues like the audio stops or sputters with a slow internet connection, just like watching a YouTube video. Moving the playhead around, also like with YouTube, might help to get music playing again.

Winter 2014

  • Likely resolved. Please notify us if you experience long wait times launching ArcGIS. ArcGIS applications have long launch time:  In general, all ArcGIS applications such as ArcMap, ArcReader, ArcCatalog, etc. may take as long as 15-20 minutes to launch.  Please be patient after clicking on an ArcGIS application. We will remedy this issue on the Spring 2014 quarter update. Please note that your laptop needs to be connected to wireless network eduroam while on campus or to the UCLA VPN while off campus in order to talk to the campus license server to allow ArcGIS to launch.

  • Resolved! Gephi won't open on Windows laptops: On launch, Gephi displays an error about not being able to locate the system's Java installation due to an incorrect file path. You can fix this manually by editing the Gephi startup settings text file located at Start Menu > All Programs > Gephi > Startup settings. Open this file in Notepad and change the last line from jdkhome="C:\Program Files\Java\jdk1.7.0_25" to jdkhome="C:\Program Files\Java\jdk1.7.0_45"We will fix this error on the Spring 2014 quarter update.

  • Resolved! Linguistics programs have broken shortcuts in Start Menu: The PCquirerX, PitchWorks, and SynthWorks program shortcuts at Start Menu > All Programs > Linguistics are broken. Please launch these programs with the alternate shortcuts at Start Menu > All Programs > PCquirerX folder, PitchWorks folder, and SynthWorks folder, respectively.
