Systems and Network maintenance this Sunday morning

Categories: Midd Blogosphere

During our maintenance window this Sunday morning between 6 and 10 am we have the following actives planned:

We will be upgrading the Middlebury and Bread Loaf campus wireless network.  This will result in each wireless access point on both of these campuses rebooting, as a result we expect a less than 10 minute interruption of wireless services throughout both campuses, likely between 6:30 and 8:00 am.

We will upgrading the our VPN (virtual private network) appliance that provides service to the JunOs Pulse VPN client.  Between 6:30 and 8:00 am there will be a less than 30 minute service interruption of off-campus VPN access to Middlebury’s network.

We will be upgrading our MiddCloud file serving environment that includes MiddFiles and other network file shares generally used by the Science departments.  Between 7:00 and 8:00 am we expect a less than 10 minute service interruption of MiddCloud.

We appreciate your patience as we strive to keep our systems and network operating optimally.

June 16th downtime – Videoconferencing bridge & software

Categories: Midd Blogosphere

Dear Colleagues,

Due to the installation of a new firewall, the videoconferencing bridge and polycom software will be unavailable on June 16th, from 9:00am EST – 5:00pm EST. If you need access to videoconferencing software or bridging capability on June 16th from 9am to 5pm please contact me and I can provide you with an alternative.

In addition, any calls between videoconferencing rooms will need to be done using the backup addresses in the address book of each system. Please contact me if you have a video conference planned on June 16th.

We will follow up immediately after completing testing, and no later than 5:00pm on June 16th, to notify you that the software and the bridge are available.

The firewall is essential to better protect our videoconferencing equipment that is being used more extensively than ever before. We chose this date by looking at the schedule of videoconferences and the overall schedule of summer programs.

Please feel free to contact me if you have any questions.

Sincerely,
Petar

Macintosh – Middfiles – Mmmmm… News You Can Use

Categories: Midd Blogosphere

Mac users…  Are you having the best possible experience with Middfiles?  It may be time to update how you connect to Middfiles, as well as create some useful shortcuts!

First, check your connection.  In the Finder, click on the Go menu, then click Connect to Server.  You should use cifs://middcloud.middlebury.edu/middfiles and remove any “smb” middfiles favorites you may have stored, as shown.

Go>Connect to Server

Removing outdated SMB favorite

Now it’s time to create some powerful Sidebar favorites for easy access to your frequently-used folders (see sample below).  Sidebar favorite locations are visible in all your programs!  Refer to our wiki article for complete details on how to create these favorites & get rid of outdated ones.

Technical stuff:  We use the SMB protocol to connect to Middfiles almost exclusively on campus and the latest revision is CIFS.  To use the most current version of SMB you must specify CIFS in your connection.  Outdated connections may results in errors when saving to Middfiles or be slower.

Sunday morning maintenance May 18, 2014

Categories: Midd Blogosphere

This Sunday morning between 8 and 10 am we will be upgrading three of our sites from Drupal 6 to Drupal 7. The three sites are:

  • Davis Projects for Peace: http://www.davisprojectsforpeace.org
  • Davis United World Scholars: http://www.davisuwcscholars.org
  • Middlebury College Museum of Art: http://museum.middlebury.edu

Each of these sites will experience a period of 10-20 minutes during which it will not be usable.

There will also be a short period of under one minute during each upgrade when file assets on the other Drupal 7 sites may not be available. These sites include:

  • Davis Fellows for Peace: http://www.davisfellowsforpeace.org
  • Secure Forms for Middlebury: https://forms.middlebury.edu
  • Secure Forms for MIIS: https://forms.miis.edu

We do not anticipate any impact on other services.

This vulnerability is being actively exploited through Flash-enabled web sites. The vulnerability allows an attacker to execute code on the compromised system and gain access with the same level of permissions as the system user.

Microsoft is releasing patches to address this vulnerability. Middlebury’s network has enhanced security protections already in place.

Here are some protective steps that you can take on your own:

More information about the vulnerability is available on the LIS Information Security web site’s ‘Threat Bulletin’ area: http://www.middlebury.edu/media/view/476056/original/middlebury_ie_zeroday.pdf

Security Note – OpenSSL ‘Heartbleed’ Vulnerability

Categories: Midd Blogosphere

As you may have read in mainstream news media outlets, a vulnerability was recently discovered in certain versions of OpenSSL which could allow a remote attacker access to sensitive data on certain types of servers.

LIS has already patched relevant local systems and is working with vendors to ensure that any relevant externally-hosted systems are similarly patched. There is no evidence to suggest that Middlebury account credentials have been compromised.
