January 2008 Archives

UTS reports that we are experiencing problems connecting to parts of the outside Internet; the source of the problems are outside the McMaster network and ORION staff are working on things.

Some bayes & bluespruce users will have seen messages like the following when ssh'ing in after the recent upgrades: "WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!", "IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!".

These messages were due to new ssh host-identification keys being installed during the upgrades; now that I have reverted to the previous keys, the messages should go away. Except for people who accepted the new keys, who will now want to clear them again with the command ssh-prune bayes or ssh-prune bluespruce.

R 2.5 is now installed on bayues and bluespruce; BioConductor and required packages are being installed today.

Bayes and bluespruce are now upgraded and back on line. Note that R isn't yet working on either; the latest version will be installed on Friday.

Bayes and bluespruce will be down most of the morning of Thursday, January 24th so that I can upgrade the operating systems. Please let me know if this presents a problem for any long-running jobs.

NB: these upgrades were postponed from January 10th.

UTS tells me that the battery backup unit for the network link to Hamilton Hall failed again on Saturday and so the website and email were inaccessible between 2:30 am and 7:30 am. The unit is to be serviced on Monday.

UTS has announced that the campus connection to the Internet will be down from midnight on Friday the 17th to 6am on Saturday the 18th due to a network upgrade by ORION.
