- Java

Openlab Upgrade to CentOS7
All ICS Openlab hosts will be upgraded to CentOS7 for the Fall Quarter 2016. Faculty may test out this new environment today by logging into openlab7.ics.uci.edu.
A new SGE queue of openlab hosts running CentOS7 is available now as “openlab.q”.
Openlab reboot
Openlab hosts will be rebooted througout the day to upgrade the operating system to CentOS 7 or to apply the latest CentOS7 patches.
SPF Implementation
ICS will be adding SPF TXT record to our DNS. See email settings for more important information about how this affects uesrs at ICS.
On September 21st, ICS will publish a list of authorized sending hosts. After this change, email that is sent that does not originate on one of these valid email senders may be rejected.
