We are planning to install the latest version (R2011a) of matlab on sphere today.
There seem to be some problems with the matlab installer. We are trying to find a workaround, but it is not clear if the update to R2011a will work today.

The departmental servers all appear to be working fine after the updates. The mail and web servers were back before 4:30pm, but coxeter took slightly longer (less than 5 minutes) due to the large number of updates.

Please see the message about the (complete, non-backed-up) removal of the 215 Huron servers and files on 2011aug03.
Software updates at 3:45pm on Wednesday August 3, 2011
August 2, 2011 by
Note: The start time for the reboots will be 3:45pm due to summer hours.
The departmental servers coxeter, sphere, and the mail, web, and blog/wiki servers will have software updates applied on Wednesday afternoon, August 3, 2011 which will require rebooting (most servers will be unavailable starting at 3:45pm). 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 4:30pm.

Improved wireless available
July 20, 2011 by
As mentioned in an earlier post there is a useful University link for information about wireless at: http://wireless.utoronto.ca/using.
As of June 20, 2011 the wireless situation has improved. The bandwidth is better and with a modern wireless card you can use a new SSID which will not require manual reauthentication every time you connect to the wireless network.
The old SSID is UTORwin and its WEP key is UToronto1home (you should avoid using this SSID if at all possible, as it is quite insecure).
The new SSID is UofT (which uses the more secure WPA wireless protocol). You then only have to authenticate once against radius.wireless.utoronto.ca with your UTORid and password. If you have problems you can verify that your UTORid and password are valid. If your UTORid and password are valid and you are still having problems then detailed configuration instructions (for some OSes) are available.

Removing old servers and computer files from 215 Huron on 2011aug03
July 18, 2011 by
We will be removing the old servers from 215 Huron on Wednesday August 3, 2011. All the old files and backups on those systems will be permanently removed without backup. These servers were used for the Dynamical Systems lab and for people who used the machines in the computer labs on the 10th floor of 215 Huron. An email with subject line:
Old 215 Huron servers will be wiped out on 2011aug03
will be sent to all accounts on those servers shortly. Since the account names on those servers were not kept synchronized with the usual departmental account names, a link to a list of account names on those systems which are not also coxeter accounts is on this IT Status blog in a posting titled “Non-coxeter accounts at 215 Huron“.
If you have any files on the 215 Huron servers there that you wish to keep it is up to you to move them to a new location before Aug 3, 2011. Please do not hesitate to contact us at requests@math.toronto.edu if you need help copying your files or determining if you have files there.
