New Restrictions on CLEOc HyperNews Server

A HyperNews vulnerability is being exploited, leading to compromises of HyperNews fora. To protect against this, LEPP has now restricted access to the CLEOc HyperNews server using our LEPP Network Principals.

Users accessing the CLEOc HyperNews server will now have to authenticate twice, first using their LEPP Network principal. They will then need to actually login to HyperNews using their HyperNews username and password.

As usual, users can reset their network principals using the "knetpw" command on Linux or by emailing service-lepp@cornell.edu. A little more information on network principals can be found at UserAccountsAndPasswords

General network and server maintenance will occur every Tuesday from 12:00 noon to 2:00 PM. The CLASSE-IT group will always announce any expected disruptions in our NewsLetter and via CLASSE-IT-NEWS-L, but with the size and complexity of our network there is always the potential for something to go wrong. We will do our best to contain all network maintenance and planned outages to Tuesdays from 12:00 noon to 2:00 PM.

Unless other arrangements have been made, CLASSE-managed Windows systems may be updated and rebooted on Tuesday morning at 2:00 AM, so please avoid critical or lengthy operations at that time. For more details, please see SystemExpectations.
