(Not yet) Retiring webvpn service

As a followup to the announcement I sent earlier, and after forwarding on the feedback I received (as did the others in the lab), we got a great response from BIS on this.

I’ll just quote it verbatim, because it made me smile. This comes from Dave Salbego.

You guys have forwarded some very informative feedback over the past week, and I’ll summarize it below:

– Dayforce sucks

– Citrix on Linux is difficult

– Citrix is oftentimes a heavyweight answer to a lightweight problem

– There is a select crowd that uses WebVPN for quick, lightweight internal web browsing for various purposes

There is good news: the next version of the Dash service includes a client-less, browser-based option for lightweight access to applications. I believe the introduction of this feature will address many of the concerns with the pending retirement of the WebVPN service.

We’re going to keep WebVPN running for now – at least until the next version of Dash is released (date TBD).

Systems Announce compute001 down time.

Compute001 is back up. The faulty memory has been replaced, and the memory errors appear to have stopped.

You may now resume use of the system.

We will continue to monitor the system for the next few days.

Subject: [Systems Announce] compute001 down time.

We will be taking compute001 down today (June 7th 2017) at 5PM CST to replace some memory that has caused the machine to lock up a few times.

Down time should be about 1 hour. We will send an all clear once service has been fully restored.

Retiring webvpn service

The web-based VPN service run by BIS (https://vpn.anl.gov) has reached end of life, and BIS (the former CIS) would like to retire it. Before they do, they want to be sure it’s not a critical part of your work that we can’t find another solution for.

First up, this is not getting rid of VPN access. This is retiring the very specific https://vpn.anl.gov service that allows you to browse websites from an Argonne address. If you currently have a VPN account, that is unaffected.

If you currently use the VPN via that address, the options are:

1) Using dash.anl.gov. The “Inside Argonne” app presents a web browser inside the ANL firewall that can be used to browse other websites/journals from an Argonne address.

2) The tips and tricks provided at https://wiki.cels.anl.gov/IT/index.php/Getting_by_without_a_VPN_client

3) Using the actual VPN client installed on your machine – if you have specific access requirements that are not met by the above.

BIS has not yet announced an end date, but I will keep you informed as I learn more.

In the meantime, if the above options don’t meet your needs, let me know and we’ll figure out how to make sure you can do your job.

Upcoming Office365 Migrations

Hi, folks!

I’m including the very official welcome message from BIS on this below, but I wanted to be the first to fill you in on what’s happening. BIS will be working with you all to migrate your mailbox from on-premise Exchange service (running Exchange 2010) to Microsoft-hosted Office 365. I’ve been on this setup for over a year now, and I can tell you it’s a remarkable improvement! The web GUI is amazing, you’ll be able to use the Android or iOS Outlook client for your mobile if you’d like, and most importantly you’ll have fast and reliable service. And that’s just the Outlook/e-mail portion of it. You’ll be using Office 365 with the full suite of online office apps at your disposal.

I’m really happy our divisions have finally hit the migration schedule.

I’ve been through the migration process myself, and it’s quite painless — you’ll barely notice it. BIS is very hands-on with anyone who needs help, but you’ll find most things just plain work seamlessly. Also, we are not the first divisions to undergo a mass migration, so we’re not guinea pigs here. 🙂

I know not everyone on this list is affected by this – perhaps you don’t use your Argonne mailbox at all (you may not even have one by choice). I’m sending this as a broad announcement to all the of the divisions served by CELS Systems, however, in case it convinces some of you to come back into the fold. It makes scheduling so much easier when everyone’s using the same system, and it gets a whole lot easier on *everybody* for any legal/cyber issues when the mail is kept in-house.

From this point forward, you’ll get direct communications (not to this list) from the ANL Service Desk and the BIS e-mail team with the specifics of when you’ll move and what you can expect. They’re experts at this and will take good care of you. And if you need any extra help, well my team and I will help out as much as we’re able.

I’m feeling really good about this, I can’t wait for you all to join me on the new and better service.

==== BIS Welcome Message

Hello, and welcome to the Argonne Office 365 Email migration initiative.

You will find this new Email experience to be an enhancement over the existing Argonne service offering.

The CELS, ALCF, MCS, and BIO Divisional mail migration will begin on June 5, and is expected to run until June16. You will receive additional notifications regarding your individual migration day in the next few days.

A detailed migration schedule for your division can be found on this wiki (internal access only)

https://wiki.inside.anl.gov/inside/Exchange_Administrator_Documentation/Microsoft_Office_365_Migration_Schedule

In addition to the information below, you can also find all of the information relevant to the initiative on the Office 365 wiki page (accessible from anywhere) https://wiki.anl.gov/public/CIS_Email_Services/Office_365 .

Who will perform the work?

BIS will be performing the data migrations in cooperation with consultants skilled in the migration to Office 365. BIS field technicians, the BIS Service desk, and your division’s technical support will be providing post migration support.

What should you expect?

The migration is straightforward and occurs in the background while you are working.

On the day of migration, you will be able to start the day working in your mailbox uninterrupted. Once your mailbox has finished migrating, your mail client and mobile devices may need to be reconnected. We will have Email Migration staff from the Service Desk available on-site in your building to assist you if an issue arises.

Instructions for getting your client reconnected can be found at https://wiki.anl.gov/public/CIS_Email_Services/Office_365/Client_Configuration_Documents.

There are several key items of which you should be aware. Please visit the Office 365 wiki page for a full list of key changes. You can find that page at:

https://wiki.anl.gov/public/CIS_Email_Services/Office_365 .

What about my mobile phone/tablet?

Most mobile devices will lose connectivity briefly during the last steps of provisioning and reconnect automatically. If yours does not, you can refer to the Mobile device migration notes and documentation below.

https://wiki.anl.gov/public/CIS_Email_Services/Office_365/Client_Configuration_Documents#Mobile_Device_Changes_and_Configuration_Documents

As always, if you have any questions or concerns, please contact the Service Desk at 2-9999 option 2

Thank you,

The BIS Email Services Team

File Server online

Greetings, and good morning.

The file server is online and fully operational.

The server experienced a major hardware system failure. We managed in the end to salvage a mother board from a decommissioned server that was in the excess pile, a server’s death row. A last minute reprieve from the guvnuh, as it were.

This is temporary fix until we can get the original motherboard replaced by the vendor.

Youi may need to reboot your workstations.

Thank you for your patience, we apologize for the inconvenience.
