Report from Computing Executive Group
Alastair will circulate the modified Grade 8 competency framework for comment.
Reports from units.
Tom replaced the failing KB UPS batteries on the 27th. We discussed whether the UPS mailing list should be split up to prevent the Estates and Buildings people receiving alerts from the KB UPSes. Ian will look into this on his return.
Stephen reported that it may be possible to produce a 64bit version of the latest om if the appropriate libraries are included in a future release of OpenAFS 1.4
It was agreed that Iain should report back to the meeting on the progress being made in porting components to F12. He should also produce Bugzilla entries for those components needing porting.
It was agreed that we would hasten the final demise of platspecdots by not including the appropriate AMD map entries in F12.
Neil drew the attention of the meeting to an issue we had experienced the previous week when the installation of a new sendmail rpm apparently rewrote the mail server's sendmail.cf file despite it being marked as a config file. This resulted in the mail servers not relaying mail for several hours. Though we suspect the sendmail rpm, we haven't been able to replicate this behavior. Stephen suggested adding a trigger to the mailng component which would re-run the configure method after a rpm update.
The meeting was reminded of the particular importance of maelcum during on-line exams.
Topics for discussion
It's clear from a study of the new Health and Safety web site that it doesn't cover a large number of activities which the computing staff are required to carry out. Amongst the issues identified were
In addition, it was pointed out that none of the risk assessment forms include a computing staff category.
It was agreed that Alison, our representative on the Health and Safety committee should compile a list of our concerns and present it at the next Health and Safety committee meeting.
George pointed out that when the infrastructure had been set up for the KB server room, it had been designed on the assumption that the kit at KB would only be used for disaster recovery. At the moment, there is some commodity date, mainly AFS RW volumes stored on KB servers. Craig stated that the intention was to move all AFS RW volumes downtown in the near future. This does mean that we will see considerable network traffic between the central area and KB every night as the RO mirror volumes are updated and we will need to monitor how the KB infrastructure copes with this. We have a deadline of August for deciding whether we need to upgrade the network connection to KB. It was pointed out that Physics will shortly be installing DR kit in the Forum server room.
Stephen reported that we are now running fail2ban on the ssh servers. When login failures from a given IP address exceed a certain limit, further connections from that address are blocked via the hosts.deny file for a given period of time. Stephen is monitoring the behavior of this script to make sure that the various time limits have a reasonable value. It was agreed that user support should send a suitably vague message to the user base announcing that this measure had been put in place.
The next meeting will be on Wednesday 12th May in room 4.31.
