News and Announcements from the MCS Systems Group

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.

Update: Confluence server (collab.mcs.anl.gov) is back

And we’re back. Things should be at the pre-upgrade state in terms of functionality. We’ll do some more dry runs on the upgrade before attempting again. Thanks for your patience.

Update: Confluence server (collab.mcs.anl.gov) mostly back

The server is mostly back — there are some aesthetic issues we’re still ironing out, but main functionality should be there for everyone. Will send more when things are closer to done, but you can feel free to use it again. Sorry for the inconvenience.

Outdated OS and external connectivity.

This is an update/followup to this post: http://wp.me/p3jwfN-5Z

As older versions of operating systems and browsers stop being supported, the lab will be blocking their access to external sites to help prevent malicious sites from exploiting unpatched security issues. Windows XP has been blocked since April, for instance, as have older versions of Mac OS. (This blocking is implemented on the lab’s wireless networks and VPN. The MCS wired desktop network does not *currently* block this traffic.)

The following additions have been made to the lab’s blocking policy. Allowable versions are listed below — if you’re running an older version, you will need to update. Machines that are maintained by Systems will be up to date, so this really only applies to self-managed machines.

* Mac OS 10.7.5 and newer are allowed
* Mac OS 10.8.5 and newer are allowed
* Mac OS 10.9.2 and newer are allowed — note 10.9.3 was just released, so this may change to reflect that in not too long.

* Java 1.7.0_55 and newer
* Java 1.8.0

* Chrome 33.0 and newer

* Firefox 24.0 (primarily included for linux distributions that have patches included, v25-27 are blocked) * Firefox 28.0 and newer

We’ll send reminders on this from time to time, but in general you should know if you’re being blocked due to outdated software.
