Oracle Issues with Firefox v37 and Newer

If you are running Firefox v37 or a newer version, you may be experiencing issues connecting to Oracle. These new versions of Firefox do not support the security certificate that is currently supported by Oracle, Exeter and Famis. We are currently working with Oracle to resolve this issue. Below is a temporary workaround.

Workaround

  1. Use a different browser such as Google Chrome, Internent Explorer, or Safari
  2. Implement a workaround in your Firefox browser
  • NOTE: The solution below is only temporary and must be reversed once this issue is resolved. We will post an update once the issue has been resolved. 
  • In the Firefox address bar, type about:config

  • At the This might void your warranty! warning screen, click on the I'll be careful, I promise! button

  • Once the configuration page is displayed, type tls into the Search: bar

  • Double click the security.tls.insecure_fallback_hosts entry

  • Type oracleapps.caltech.edu

  • Click OK and completely close your Firefox browser
  • Re-open Firefox and connect to the needed site

For questions, please contact the Help Desk at x3500 or via Caltech Help (https://help.caltech.edu

IMSS recommends upgrading Eudora email clients

After a recent update to campus email, the Eudora email client is no longer compatible with the standard UNIX mail system. Customers using Eudora may no longer be able to access their mailbox. Since the latest version of Eudora was released in 2006, it is unlikely that we will find a solution for customers to continue to use Eudora. IMSS instead suggests upgrading to Mozilla or any other modern mail client, or using webmail. For further assistance, please contact the Help Desk (x3500, help@caltech.edu, https://help.caltech.edu.)

Beware Fake IRS Emails

Tax time brings IRS scam email messages.  A variety of scams are circulating in email right now purporting to be important messages from the IRS.  Be very suspicious of any incoming email message that claims to be from the IRS, particularly if it includes an attached document.  One current example is a message claiming to provide information about a tax refund, in the form of an attached Word document.  Very few antivirus programs are detecting this malicious document at present; however, be aware that the IRS does not communicate refund information in the form of emailed attachments.  If you are expecting a refund and wish to check its status, visit the IRS Refund information website instead: http://www.irs.gov/Refunds

Don't Be Fooled By Messages Asking For Your Caltech Username And Password

Many campus users are receiving email claiming to come from an IT support group (sometimes even IMSS or the Help Desk), asking for the user's password and other private information, or requesting that you "verify your account" by logging into a website. Please be aware that this is a form of security attack known as "phishing" designed to fool users into giving their usernames and passwords to an attacker. Please do not reply to these messages or visit any websites they may refer to. IMSS does not recommend providing usernames and passwords by email, and IMSS will never ask users for their passwords by email or by phone under any circumstances. When visiting a website, be sure to check the address bar on your browser to confirm that the site you're visiting is the one you were expecting. If you receive any confusing or worrisome email messages about any of your Caltech accounts, we strongly recommend contacting the IMSS Help Desk (626.395.3500 or https://help.caltech.edu) or your local system administrator. In the event that your password is exposed to an attacker, please be sure never to use that password again, for any purpose, and particularly never for the account it once belonged to.

Example:

Java 8 Update Information

Java users may have recently auto-updated or received prompts to update from Java 7 to Java 8. Though Java 8 is currently the default version on http://java.com, Caltech users may want to reconsider updating to Java 8 due to compatibility issues with some applications. If the Caltech administrative applications are an integral part of your workflow, IMSS does not recommend updating at this time until we can address these compatibility issues. If you have already updated and need to revert back to Java 7, you may still download Java 7 from the Java Archive.

If you have any questions about this, please contact the Help Desk (x3500, help@caltech.edu, https://help.caltech.edu).

Red Hat Proxy transitioning to Satellite on 2/9/2015

Effective February 9, 2015, the IMSS-run proxy server which registers campus Red Hat systems to receive updates will be retired and transitioned to a new Satellite server. In order to continue to receive RHEL updates, you will need to download a new script to register your systems to receive updates. 

Instructions on how to obtain this new script can be found on the Caltech software webstore. If you previously ordered RHEL from the software webstore, you can find these updated instructions in your software order details:

  • Go to http://software.caltech.edu and click on Log In
  • Enter your access.caltech credentials
  • Click on Your Account/Orders at the top of the page
  • Find your previous RHEL order and click View Details
  • Click on the link Instructions for obtaining Red Hat updates
  • Otherwise, simply place a new order for RHEL to obtain these instructions. 

Also note that effective 2/9, toughguy.caltech.edu, a former RHEL resource, will be retired. 

If you have any questions about this, please contact us at https://help.caltech.edu, request type IMSS > ​Software Licensing & Distribution > Other.

Update your Matlab license file

Effective 12/12/2014, IMSS retired the long-running Matlab triad license servers. If you are using a network installation of Matlab, please update your license file. This will ensure that your Matlab network installation accesses the new replacement license server. For instructions on how to obtain and update this license file, click here.

NOTE: Standalone installations do not need license files updated since they do not require network access to run. However, if your standalone installation displays a notice that the license has expired, you will need to renew your license for another year. To renew your license, please follow the instructions located at http://imss.caltech.edu/software/matlab-license-renewal-instructions.
