Introduction to the Junos Pulse VPN client

We’re delighted to formally announce a significant enhancement to the College’s Virtual Private Network (VPN) service that offers a faster and more convenient way to establish a connection from off-campus to Middlebury’s network.  The Junos Pulse client is available for a wide variety of computers and mobile devices that include: Macintosh, Windows, iOS (iphones, ipads), and Android.

For Macintosh and Windows platforms, the Junos Pulse client may be downloaded from Middfiles at:  https://middfiles.middlebury.edu/Software/Public/Junos%20Pulse – to access this download site you will be prompted to enter your Middlebury Network username and password, this site is accessible from off-campus without first establishing a VPN connection.

A special note for Windows 8 users.  Do not install the Junos Pulse client for Windows 7 on your Windows 8 computer, rather if you’re running Windows 8.0 upgrade to Windows 8.1 and the use the built-in VPN tool to configure the Junos Pulse client that is embedded within Windows 8.1.  Please follow these instructions for Windows 8.1 computers:  http://technet.microsoft.com/en-us/library/jj613767.aspx.

For iOS (iphones, ipads) devices, please visit the Apple store and search for junos pulse.

For Android devices, please visit the Google play store and search for junos pulse.

Details on how to install and configure Junos Pulse are available here:  http://go.middlebury.edu/vpn.

While you will be able to continue to establish a VPN connection the Middlebury’s network from off-campus using the Junos “NetConnect” client or by visiting https://vpn.middlebury.edu for the next several weeks, we strongly encourage you to transition to the Junos Pulse client.  Indeed, on or about April 30th, 2014, we will redirect the current login page at https://vpn.middlebury.edu that uses the Junos “NetConnect” client to http://go.middlebury.edu/vpn that contains our instructions on how to use the Junos Pulse client instead.  We have received a number of positive comments from those who have already transitioned to using the Junos Pulse client.

As always, we welcome your feedback and are ready to assist you with this transition; if you run into trouble or have questions, please open an LIS help desk ticket, email us at helpdesk@middlebury.edu or give us a call at the helpdesk X2200.

Sunday morning maintenance

This Sunday morning between 7 and 11 am we will be upgrading our printing tracking solution Papercut to v14.1. Upgrading the server side components will take place first, this phase is expected to be completed by about 9 am.  This will then be followed by site visits to the public printing release stations throughout the campus to complete the upgrade.

Each of the following servers will be off-line for about 10 minutes, each between 7 and 9 am or so, they include:

  • Papercut
  • Willow
  • Spruce
  • Bombay
  • Beech
  • Walnut

We also expect about 30 minutes of interruption to the “web print” service during this period.

Printed jobs will be queued up and automatically resubmitted during the service interruptions to the print servers.

There are several new features and fixes to known problems available in this release, additional details are available here:  http://www.papercut.com/release-history/.

Sunday morning maintenance

This Sunday morning between 7 and 10 am we will be performing some fine-tuning of our Internet gateway routers and firewalls that will include some Internet routing prioritization and optimization as well as some firewall configuration changes.  We do not expect any noticeable interruptions of services but are performing this during our maintenance window as a precaution.

Sunday morning maintenace

We have two maintenance actives this Sunday morning.

Between 8 and 9 am we will be moving our on-line guest registration web application (https://middguests.middlebury.edu/) to a new server.  We do not anticipate a noticeable interruption of service.

Between 10 and 10:30 am we will be upgrading the central authentication service (CAS) component of Moodle, we expect a less than 5 minute service interruption.

We appreciate your patience as we continuously strive to keep our system functioning optimally.

Sunday morning maintenance

Between 7 and 9 am we will be upgrading our Internet firewalls.  While the Internet firewalls are a pair with failover, there can be an up to 30 second interruption of service as each failover takes place.  We are expecting 3 less than 30 second Internet service interruptions during this period.

Between 8 and 10 am we will be re-routing connectivity to a specialized video conferencing network segment, the video conferencing service will be off-line during much of this window.

Between 8 and 9:30 am we will be upgrading Web Help Desk, there will be a less than 10 minute service interruption during this period.

Sunday morning maintenance

This Sunday morning we have a number of maintenance activities planned.

  • Between 6 am and 10 am Digital Collections at Middlebury / CONTENTdm (middarchive.middlebury.edu) will be off-line in order to upgrade to version 6.6.
  • Between 7 am and 8 am there may be a less than 5 minute interruption of DNS and DHCP services as the underlying systems for these services are upgraded.  As these services are part of a high availability configuration, we expect a minimal if any impact to end users.
  • Between 7 am 10 am we will be testing the failover of high availability components of our network that include building aggregation switches and redundant uplinks for the below buildings, no service impact is expected:
    •     Service Building
    •     Axinn
    •     Public Safety
    • Between 8 am and 10 am we will be evaluating some Internet routing options that may result in isolated, intermittent Internet sites being reachable, we expect this impact to be short lived and not wide spread.
  • Between 8 am 10 am we will be running some network/server security tests that we do not expect to have a noticeable impact.

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

This Sunday morning between 7 and 8:30 am we will be performing maintenance on one of the supporting database servers of the College primary web sites (www.middlebury.edu, www.miis.edu).  As the supporting databases are part of a high availability cluster we do not anticipate a service interruption but are performing this activity during our established maintenance window as a precaution.
