Dispatches From The Geeks

News and Announcements from the MCS Systems Group

Videoconferencing at Argonne

The lab is looking into what it’s going to do for a conferencing solution going forward. We currently use Adobe Connect (which is up for renewal at end of the fiscal year) as well as ReadyTalk (which is going away at the end of the FY). If you have any thoughts on what you do and don’t want in a videoconferencing solution, please pass those thoughts on to me. I’m part of a working group to help decide what the lab should pursue and want to make sure I have a good grasp of what you feel is working well and what is lacking.

Think about what features are important to you. Is video important? Phone links/audio bridge? Recording capability? One to one vs. seminar style? Screen sharing/control? Something I’m not thinking of?

Also, do you have tools that you think are especially worth considering?

Let me know. Thanks!

All,

We’re going to postpone this upgrade. WordPress put out a new major release since the first upgrade announcement yesterday and we’ll need to test it first.

thanks!

Be diligent in protecting your account, data, and equipment.

The lab is going through a cyber-security audit this month, which will have a few phases. They’re going to be trying any number of things to test our defenses and our ability to recognize and deal with cyber threats. Social engineering/phishing is almost certain to be part of their toolkit, and at some point they’ll even have physical access to the building.

I’ll send another reminder as we get closer, but I wanted to make sure everyone was in the right mindset. The recent phishing attack simulation demonstrated there were some holes and that people can be fooled. So, let’s be on our toes. Lock down or lock up any equipment that’s going to be unattended. Don’t fall for password reset mails. Or phone calls.

Remember — nobody ever needs to know your password. As a system administrator, if I need to know your password, I can change it to something I know and tell you want it is. You should never need to reveal your password to anyway.

Thanks!

Reminder: Windows XP (and Mac OS 10.6 Snow Leopard) End of Life.

Below is the notice I sent out last month on this. This is just a reminder that it’s happening today. I neglected to mention in the prior notice that older Mac OS installations would also fall into the End of Life rule, and thus anything running MacOS 10.6 or earlier will not be able to access the web from the lab’s wireless or VPN infrastructure. Sorry about that, it was an oversight on my part. If you have a machine that’s affected by this, let us know and we’ll work to get you upgraded or find a solution. Thanks!

Prior announcement:

Hi, folks. For those who don’t know, at the end of the month, Windows XP is finally going to be deemed “End of Life” by Microsoft. This means no more security updates, and it’s officially an unsupported OS. As part of security mitigations for this, the lab will be clamping down on Windows XP being exposed to the outside world. The first step in this is that come April, any web traffic that’s detected to be coming from Windows XP will be blocked by the lab’s web proxy. This will affect anyone on the VPN or using the lab’s wireless infrastructure, all of which is behind the web proxy. But also, we need to document any Windows XP systems that need to continue running. We have no systems that meet this criteria in our officially supported infrastructure, but if you have any that you’re using and rely on for your research, you should let us know if you haven’t already been approached on it. Any systems that need to remain running Windows XP need to be protected by a firewall, and we need to make sure that is indeed the case. Please report any Windows XP systems you need running to systems at mcs.anl.gov. Likewise, you can ask any questions at that address, or to me. Thanks!

Mailman list cleanup

Just a heads up that over the next couple of weeks, you may get some mail from me regarding mailman list cleanup. The messages are legit, there should be no embedded links, and they will merely inform you that unless you take action, the list mentioned in the subject will be retired.

As a first pass, I’m sending them to the list owners of any lists that haven’t seen any action since Dec 31 2011. More details will be in the message. If you manage multiple lists, you will get multiple messages. Sorry about that, but it’s the most efficient way to make sure everyone is notified.

Just want to make sure we don’t set off any phishing alarms. :)

Thanks!
