The departmental servers coxeter, sphere, and the mail, web, share, ptr, and blog/wiki servers will have software updates applied on Wednesday afternoon, May 14, 2014 which will require rebooting (most servers will be unavailable starting at 4:15pm).  Since some updates will be applied while the servers are still up there may be some temporary issues with some software. We hope that any such issues will be minor and by doing most of the upgrading before bringing systems down the shorter downtime will be worth the potential minor problems. Please restart any programs if you observe problems during the upgrades (and please let us know at requests@math.toronto.edu, so we can investigate). We expect the systems to be back up by 5:00pm.

Complimentary MATLAB seminars for educators, academic researchers and students at the University of Toronto have been scheduled:

Do you need to change your coxeter (and hence mail) password?

Due to the recent Heartbleed bug <http://main.its.utoronto.ca/news/heartbleed-notice/> we recommend that you change your coxeter password.  Simply type passwd on coxeter and follow the instructions.

If you are completely certain that you have never typed your coxeter password into a website (that includes departmental websites such as mail, since it is possible that website protections were compromised) and if you never typed your password into pine then as long as you do not use your coxeter password on any other sites/machines then you would not need to change your password.

New certificates have been installed on our two main servers www and mail.  These are the main servers where people might type in passwords; the other math.toronto.edu servers that use certificates will be updated on Monday.

The escalator.utoronto.ca sites are waiting for new certificates from the University.

Heartbleed bug

It seems that only the web servers and mail in our department were affected by the Heartbleed bug.  We patched all of them immediately (which necessitated the coxeter reboot on Wednesday) and now are waiting to install updated certificates for our various servers.  Until the updated certificates are installed changing passwords and using them on our web or mail servers is not protected.  We hope to have the new certificates ready on Monday and at that point we will have more information about password resets.

Networking issues today

Earlier today there were some networking issues in the department due to failing ports on our main switch which caused various connectivity problems to various people (some people had trouble connecting to coxeter, others to the mail server and others to the printers).  Everything seems to be back to normal now.

coxeter will be rebooted at approximately 4:15pm tomorrow (on Wednesday, Apr 9) in order to apply some updates due to the recently disclosed openssl problem.  We expect coxeter to be back up by 4:30pm.

The other departmental servers have already been updated and will not be rebooted.

We have recently been told that the installation of complete wireless coverage for the Earth Sciences Centre has now been scheduled and that it should be completed by the end of May.  New high-performance 802.11ac access points will be used.  This will be welcome news for our departmental members in ESC who have had to contend with very spotty wireless coverage in there for quite some time.

The departmental servers are working fine after the updates.
