Dispatches From The Geeks

News and Announcements from the MCS Systems Group

“Dash” Mobile Platform (also includes access to Dayforce)

For those who missed the announcement in Argonne Today last week, the lab has rolled out a new platform for accessing internal applications called “Dash”. The goal for this is to provide a one-stop solution for internal lab applications (including Dayforce) without requiring the VPN, and better protect the lab from possibly infected mobile and user-owned devices. Included below are links to the announcement and information page. Those who appreciate irony will note that you must be on an internal network or VPN to read these links.

I’ll also note that I have not yet been able to use Dash to access Dayforce from my Android devices, despite the claims of support. I’ll send an update if I ever figure it out. I have not yet tested iOS. MacOS worked just fine.

If you currently access Dayforce directly via the unsupported-provided-as-a-convenience link for those with Silverlight installed, you can continue to do so with no changes. Likewise, if you connect to rdp.mcs.anl.gov (Windows Terminal Service) to access Dayforce, that will continue to work as well.

ANNOUNCEMENT: CIS Maintenance Weekend August 15-17, 2014

CIS has a maintenance weekend scheduled for August 15-17. The details follow. Please let us know ASAP if you have concerns about this maintenance window. Please note the outage to the Argonne website (http://www.anl.gov) will also affect the MCS website at http://www.mcs.anl.gov, as it’s hosted on the same service. Otherwise, services provided by the CELS systems team will be unaffected.

WHAT ARE WE DOING?

Argonne’s quarterly IT maintenance weekend is scheduled for Friday, Aug 15, thru Sunday, Aug 17. Expect that any laboratory network and core IT services may be effected during the weekend.

Specifically:

· Wireless networking will experience outages throughout the weekend.

· Voice mail will be unavailable from 6 to 8 p.m., Friday, August 15th. During this time, voice mail messages will not be received nor will they be retrievable.

· Inside Argonne, the main Argonne Website, Inside Argonne Blogs, Web applications and a few business applications will be unavailable from 7 p.m. to midnight on Friday, August 15th.

· Authentication to Cloud applications such as BOX, Dayforce and Service Now will be unavailable from 1 p.m. to 2 p.m. on Saturday, August 16th.

· All business applications will be unavailable all day Saturday and into Sunday morning.

· MIR3, the labs mass-communication system, will be unavailable from 7:00 p.m. on Saturday until 7:00 a.m. on Sunday while the vendor performs its maintenance.

· CIS will perform verification of IT services on Sunday, August 17th to ensure all services are functioning for business hours on Monday, August 18th.

As with all IT maintenance weekends, there is no explicit guarantee that a service will be available at any given time.

WHEN WILL THIS OCCUR?

Aug 15th, 2014, 5:00 p.m. thru Aug 17th , 2014. We expect the maintenance to be complete Sunday morning and will then be followed by a verification process.

Display in 3178

Please note the setup for the display in 3178 has changed. There were some failures in the components that were running it previously, and replacing those components didn’t seem to help. There are new and concise directions printed and posted next to the display. They are also included below.

To use the AppleTV, the TV needs to be on HDMI1 input. You can change the input on the side of the TV by pressing the “Input” button until the desired one is highlighted. There are on-screen directions on how to connect to the unit. (At the moment, we are awaiting CIS to put the wifi reservation into place. That should be in within a day, but the AppleTV will be off-network until it’s done.)

To use the wired HDMI connection on the table, the TV needs to be on the HDMI2 input. Plug the HDMI cable into your laptop or dongle. The TV will output 1080p nice and crisp, so if the display doesn’t look right, check your laptop’s display settings.

If you need DVI, attach an HDMI to DVI adapter to the cable. If you don’t have one, you can ask for one at the help desk. I’ve left them in the room in the past, but they must be getting lost.

To use the wired VGA connection, follow the directions above for HDMI, but instead of plugging the HDMI cable into your laptop, plug it into the HDMI/VGA converter on the table, then plug the VGA into your laptop. This picture quality is obviously lower than HDMI and isn’t recommended – it’s supplied by request for older machines that need it. If you can output HDMI, you’ll have a much better experience if you use that instead.

The automatic source switch that switched between HDMI and VGA is what seems to have been the cause of the problem. Removing this seems to make things work just fine again.

Thanks!

Android Security Warning

Please see Matt’s note below on a security vulnerability that affects Android users. Here’s the short version – there’s an issue that allows applications to masquerade as trusted apps. Google has identified the issue and is pushing out a fix. The fix is not there yet, and when it gets there will be dependent on your phone’s manufacturer and carrier. For instance, Nexus phones will probably get the update quickest. As soon as you get notified of the security update, please apply it. This only affects Android users, not iPhone users.

You can download and run this tool to assess if you’ve been affected. If you have, feel free to come to us for help in dealing with it. Right now it’s expected you will show up as “Vulnerable” to the “FakeID” bug. The others should show Patched.

Thanks.

On the heels of the new IT Access Agreement to include BYOD, a security company has discovered a flaw in the Android OS. There is a patch available that has begun to get distributed to the open source code base as well as to manufacturers. It is in the new IT access agreement to keep personal systems patched and up to date.

You can read about the vulnerability here:

Web and FTP directories read/write again

We migrated the sites to the new server and re-exported the data. You should be able to read/write to these directories again. We’re spending the next couple of days looking for potential fallout from the move, so please let us know if something isn’t behaving as expected.

Web and FTP directories are temporarily read-only

The disk that serves our FTP and MCS websites hosted in MCS (as opposed to the main MCS Drupal website hosted on the Argonne web server) has developed an error that was causing the server to crash. We’ve set the disk to be read-only while we sync the data to a new disk. We’ll send an announcement when this is resolved, but for the moment expect /mcs/www.mcs.anl.gov, /mcs/web, /mcs/ftp, and ~/public_html pages to be either inaccessible or read-only.

Sorry for the trouble.

UPDATE: Quick Update: We expect to have read/write access to the affected web hosts later today (July 16).

Emergency server reboot

We’ve encountered a problem that requires an unscheduled reboot of one of our primary virtual machine servers. This reboot will take out some core services briefly. Until things come back, many websites, git repos, mailing lists, and other services will not respond correctly. I’ll send an update when it’s resolved.
