Slack Question - Plus Program

Sysadmin - Fri, 09/21/2018 - 17:35


My apologies for the random question for this application, I'm wondering if someone here would have the answer since a sysadmin may have set up a Slack channel in the past. I had a question regarding exporting my team’s conversation history. If I upgraded my Slack workspace from our current Free plan to the Plus plan, I understand that I would then have access to export entire chat history, including Direct Messages. Would the data export include messages sent before the Plus plan upgrade or only afterwards?

Any good books discussing the 0-1 matrix (aka: binary) representation of relations?

Computer Science: Theory and Application - Fri, 09/21/2018 - 17:21

I'm going through a Constraint Processing book. Most algorithms represented are in "relational" style. That is, constraints are "cross joined" or "projected" onto each other. Just like relational databases. (Ex: Dr. Dechter describes Arc Consistency as "Constraint Cross-joined with a Variable's Domain". While Path-consistency is discussed as "Constraint X cross-join Constraint Y cross-join Variable's domain").

Anyway, the book more or less assumes you're doing things with the standard Table-representation of relations. But it has a throwaway line about the 0-1 matrix representation of relations, and never really elaborates on this representation (aside from it being possible).

Because my particular use case has a very small domain-size, I think that the 0-1 matrix representation might be useful. I've written up some basic functions which implement a few primitive operations (select, join and projection), but I'd be more comfortable if I had a book to guide me.

Is anyone aware of a book on the subject?

The only book I'm aware of on the subject is maybe Volume4 of Knuth's "Art of Computer Programming". However, Volume4 is yet incomplete (and the important constraint-programming section is planned but not yet published in any fascicle). I've briefly looked at other constraint-programming books but none of them seem to elaborate on the 01 matrix representation either. I'm wondering if I'm looking in the wrong spots and maybe need to look at relational theory or something to find this info...

For people who aren't aware of the 0-1 representation of relations, I've written a post elsewhere on the subject. Its certainly an exciting subject to me, but I assume that someone else has already mastered this subject matter and maybe I can learn from them.

Oreo - Remove Statusbar Notification?

Tasker: Total Automation for Android - Fri, 09/21/2018 - 17:12

Hey guys,

My phone just got upgraded to Oreo. Is there a way to have the notification not appear in the status bar?

I do not want to remove the notification itself, just the icon.

Previously, I was able to have the icon set to nothing. The notification was in the pull down, but nothing in the status bar. This option seems to be removed.

What are my options?

GSuite Fresh setup, New accounts suspended, Preventing data migration

Sysadmin - Fri, 09/21/2018 - 16:55

New G Suite account setup for a new client. Client has 41 users migrating away from an on prem Exchange 2010 server. Client has decided to use Google for hosted mail. Decided to use the G Suite migration software rather than the web conversion tool.


I setup the G Suite account and did all the domain verification. Created the users via CSV file import. Did not originally notice but some of the users were automatically suspended for lack of verification. Set up all the API access and began to test conversions. The pre-checks before the conversion were failing with error messages indicating that I did not have "super admin" access for contacts and calendar data. Email appeared to be fine.


I then discovered the automatically suspended accounts and figured out they were the cause of the pre-tests failing. These accounts could not activated from the Admin console. The only way to activate them was to login via the account credentials and provide a phone number to receive a verification code. A phone number could only be used 4 times before a new phone number would be required. Since only a few accounts were suspended I proceeded to activate those accounts. When I finished activating the suspended accounts the rest of the accounts suddenly suspended for the same reason. I attempted to delete and re-create the accounts however all accounts created after this point were created as suspended.


Spent a few hours with Google support chat and had no options provided. The auto account suspension is only supposed to hit random accounts and there is no way to override it. Since I can convert email I'll convert that and deal with contact and calendar data after users have logged in.



  • New G Suite accounts are randomly suspended pending phone verification (mine were all suspended)

  • Google cannot override

  • While the account is suspended you can migrate email but cannot migrate contacts or calendar data

  • Only way to activate is to login to the account and provide a phone number to receive a verification code

  • Each phone number can only be used to activate 4 accounts

DNS issues - domain the same name as our website.

Sysadmin - Fri, 09/21/2018 - 16:33

Ran into an issue that apparently has been on-going for a while. Our remote offices are unable to go to our website since our domain name is the same as our website name. Errors our everytime they try to go to it.

I know this isn't best practice to do it like this anymore and recommend to change the domain to corp.whatever but that is nor here or there.

An A record has been created, but still doesn't do the trick.

Anybody have any ideas on how we can get past this issue?

thank you

Any other NetApp AltaVault Customers? Plans now that it was announced discontinued?

Sysadmin - Fri, 09/21/2018 - 16:26

So, I heard from our VAR that the NetApp AltaVault line is being discontinued Jan 2019. Huge bummer for us, we love ours and it got us away from tapes which has been very nice the past few years.

I'd assume support will be for years yet, but it would be dumb to keep using it to jam stuff in Azure only to have to pull it all back down in a few years. It would compound the issue of getting the data back down to put on another medium.

Any discussion on what you are going to do after AltaVault? As far as I am aware, that was the only dedupe/cloud archiving device of it's type. Sure there is the HPE storeOnce that does cloud archiving but it doesn't play nice with Veeam.

Cloud connect or direct to cloud aren't really a option, the data needs to be deduped and compressed before it goes out there.

For me, Looks like I may be going to some Quantum DXi devices and their Scalar converged tape device.... :(

Sysadmin - Fri, 09/21/2018 - 16:05

Hi all,

I've only been a sysadmin for the past 3 months, so I just want to say you all are amazing. I love reading every post on this sub and I learn so much from them.

I don't want to start a debate here, I just want to know what OS other system Admins use?

And if there any things I should do to my android device that might help me with my job?

I love the "ping tools" app it's just amazing.

Thanks for reading :)

FSLogix profile container IE cant reach google

Sysadmin - Fri, 09/21/2018 - 15:52

IE11, Windows server 2016 standard desktop experience, FSLogix profile containers handling user profile disks

We have a strange issue with a new terminal server farm we spun up to migrate users to FSLogix profile containers.
On the server farm, users cannot reach any google domains using internet explorer. This effects any website that pulls its jquery library from the google API as well.

Other browsers are able to reach the domain just fine, and i'm able to wget the contents of google with powershell from the servers.

I've tried every setting in internet options that i can think of.

The problem goes away for the users session if you reset the browser and check the 'delete personal settings' box.

Has anyone seen this behavior before, or does anybody have any troubleshooting advice based on the information above?

Zoom + Zscaler Issues

Sysadmin - Fri, 09/21/2018 - 15:27

Anyone else use Zoom client with Zscaler hosted proxy and have problems with link preview?

When you send URLs in an IM the Zoom client tries to preview it (similar to facebook messenger). Some URLs are blocked or cautioned by Zscaler, such as social media. When you send one of those URLs in a chat and it tries to preview it Zscaler blocks it but Zoom doesn't play nice and instead prompts for authentication which will always fail.

We can't whitelist those problem URLs because they are blocked for a reason. We can't make Zoom bypass the proxy because PAC file isn't aware of the user agent string, and even if it was the end user device wouldn't have direct internet access so it would be blocked anyway. Even with link preview disabled in the client it still tries to access the blocked content.

Zscaler say they are aiming at November(!) for a fix.

Just wondering if anyone else has this issue and found a workaround?
