Redhat Linux Systems are firewalled
Written by Janaka Jayawardena   
Monday, 16 January 2017

As of late December, 2016, all our CAT supported RedHat systems are firewalled from the Internet. This is to prepare us for end-of-support for RedHat 5 as well as the slower distribution of patches. Systems affected are:

If you are accessing these systems remotely for the purposes of ssh/VNC/X, you will need to ensure that you are on the VPN. To learn about OpenVPN access to the MCECS network, start here:

[If you are a Linux user on a college or departmental Linux system and you use a graphical interface (or “desktop”), this notification applies to you.]

Our automated termination of idle VNC/X sessions has been in place for many years. As of Fall 2016, we also introduced automatic termination of Linux workstation logins deemed to be idle. Details of how these controls work are documented on the CAT website at:

1/6/2017 - Lab Printing moves to msprint - old print server will no longer work
Written by Janaka Jayawardena   
Wednesday, 04 January 2017

If you print in the MCECS computer labs this term, make sure that you switch your Windows printing over to the new print server, “msprint”. User access to the old print server (“hela”) will be shut off for the following computer lab printers on the evening of Friday, January 6th:

FAB 55-17 MCECS General Lab: fab5517bw1, fab5517bw2, fab5517clr1

EB 325 MCECS General Lab: eb325bw1, eb325bw2, eb325clr1

EB 420 MCAE Lab: eb420bw1, eb420clr1

FAB 60-01 Tektronix Lab: fab6001bw1

CS Lounge: fabc8802bw1

If you have not changed your print server to “msprint” by then, you will not be able to print to these specific printers. Windows printing to other smaller volume departmental printers will continue to be supported from hela for the time being (although that will also be phased out soon.) Information on how to switch to printing to “msprint” on a CAT supported Windows system can be found here:
