What hypervisors are you Linux shops running these days?

43 min 55 sec ago

I work in a predominately windows shop with very few Linux machines and by no means would I consider myself a Linux guy, however I’ve been dabbing more and more into the Linux world and finding out I am liking it the more I get involved.

My goal is to replace as many windows services with linux in my lab so this leads me to the question of what are you Linux shops running for hypervisors?

[Surface Pro 3]Microsoft Edge not detecting any printer.

56 min 37 sec ago

Hey guys,

Long time lurker in-between tickets.
I've thought I'd ask for some help here as I'm facing quite a puzzle since month.
I'm currently working with a Surface 3 park using intune as MDM.

Most of those machines seem to have a common problem,
Edge, is incapable of reaching any printer. Be it network, or local(XPS printer).
I've read and experimented for a month now trying to find a solution. To the point of researching during my weekends. But can't seem to do so.

I tried many things.
Remapping the printers
Reinstalling the drivers

Those steps give me very inconsistent results. Sometimes working, sometimes not.

Even reinstalling the OS doesn't seem to resolve the issue every time. It's more of a 50/50 success rate.

I was wondering if any of you ever faced something similar.

Interview Coming up Ansible + Linux

Fri, 03/16/2018 - 22:41

Passed a phone interview heading into a real interview. I know I was weak on Ansible and Linux. I have used Linux for along time but not at this scale. It's a few hundred Linux servers managed with Ansible and their hoping to start utilizing AWS more.

I have begun spinning up VMs. What should I be testing in my lab to gain some familiarity. It sounds like their primarily application servers. Should I just be looking at automating a LAMP stack? And even automating migrations and management of hybrid and onprem with Ansible?

Theirs also some windows boxes, are people generally using Ansible much with winrm?

Setting Up Different Domains

Fri, 03/16/2018 - 20:58

I work for a company that created a product that did well enough that they want to have it be its own company. They kept the same company.local domain and added shares for this new company on the same domain. Employees for the new company are tied to the same AD, so their logins are first.last@originalcompany.local.

I am not the sysadmin, but we are talking about bringing our infrastructure up to Server 2016 (currently 2008 R2) and he mentioned cleaning up the domain controllers or retiring them and starting over. We have around 130 employees and the new company has about five. At what point should we (or should it have been done from the get-go) make the new company its own domain? They are also both housed in the same building and share resources, but both are set to grow considerably. I thought this might be something to discuss since he is talking about redoing everything.

Somewhat related, both companies do have their own email through Google already. If it does not make sense to do separate domains for the companies, would it make sense to keep these separated as well, or should we consider combining them so that both can be managed from the same admin portal?

Windows Clustering. 3 node, 2 site, witness where?

Fri, 03/16/2018 - 20:37

I wanted to put this out to the masses to answer. I am looking for the best solution to this question. We have 2 sites. And a Windows cluster of which SQL AG rides on. In our primary site there are 2 nodes for HA, and 1 node in the 2nd site for DR. All servers are 2012R2. It was advised we put a file share witness in the 2nd site. Does this make sense or is it pointless? I've read putting the FSW in the primary site is optional in case the 2nd site is offline we can still reboot one of the nodes in the primary site without losing the cluster. We do not have the option of a 3rd site so please do not suggest. Thanks inn advance for any input or past experiences.

Nested VM's in production

Fri, 03/16/2018 - 19:10

Looking for some feedback on nested VMs in production. Has anyone done it? What are you using it for?

We are considering doing a nested VM in Azure so we can run two systems that have hyper-v images/deployments for them that we can't launch natively in Azure. These will be internal facing applications so there's no complicated networking involved getting this publicly facing in Azure.

Salaried OT benefits or compensation

Fri, 03/16/2018 - 19:07

Does your employer provide anything extra after you've worked all weekend/night or just an excessive amount of hours? Some give spot bonuses on big projects, or comp time, but I'm wondering how common it is. And what is too much for you until you look elsewhere?

This is a new one for me: Outlook autodiscover pointing to 365 account before I've even done anything!

Fri, 03/16/2018 - 19:01

I created the new accounts on 365 to prep for migration, but I haven't changed MX records, or DNS, or anything; they are still using their on-premise 2010 Exchange server. Yet one user's Outlook 2016 is now INSISTING on pointing to 365! The test autoconfig utility shows it immediately finding Is this now hard-coded into Outlook 2016 or something?

Did I screw myself? Expanded VMDK, VM can't boot

Fri, 03/16/2018 - 18:58

We have an ESXi 6.0 host with a server 2008 R2 VM acting as a backup server with 2x ~2.2TB VMDKs used to storage backups from the other VMs on the network. I expanded the VMDK by 500GB (from about 2.2TB to 2.7TB) and found that now the VM doesn't boot and I am greeted by an error "Device 'SATA controller 0' is not supported. This is a general limitation of the virtual machine's compatibility with the ESXi version of the selected host." We have scheduled backups that run every hour and I'm trying to run through all my options. I found quickly that I can't shrink the VMDK from within vCenter, though vCenter Converter would work. I installed vCenter Converter but found no options to shrink the shrink, and that this feature may no longer be supported? I am debating upgrading the VM version but I am not sure how risky that is. How screwed am I?

Any harm in Server 2016 VMs on 2012 R2 hypervisor?

Fri, 03/16/2018 - 18:55

Hello. I'm in the process of virtualizing all of our infrastructure and I had a question for those more experienced. My current hypervisor is a 2012 R2 server with the hyper v role installed. Are there any potential issues running 2016 VMs on this?

I have a few 2016 test VMs spun up, and the only problem I've noticed is a Microsoft-Windows-Hyper-V-Netvsc error in system log about not being able to negotiate protocol version 6.0 and 6.1, which I haven't been able to find much information on, but from the few posts out there on it it seems to be related to the VM os being newer than the hypervisor.

The other option I am considering is wiping and installing hyper v server 2016 as my hypervisor. I'm just trying to figure out if there is best practice in matching up hypervisor to guest OS level when it comes to Windows. Any advice is much appreciated!

Generate custom report from WebHelpDesk postgresql database

Fri, 03/16/2018 - 18:55

I want to generate a report of tickets matching a certain request type. The simple reporting in WHD cannot achieve this. Basically, I want a simple report where the columns are

  • Ticket No.

  • Creator

  • Open Time

  • Closed Time

  • Custom Fields

I've been snooping around the database but not sure which table custom fields are in and how to get their text descriptions.

Also, would I require separate software to actually generate this report since WHD can't do it itself? What software would you recommend?

Password protecting data in place on external HDD without the need for software to access it later on, compatible with both Linux & Windows... Any saviour?

Fri, 03/16/2018 - 18:52

Pretty much everything is in the title. For a couple of days i've been seeking a way to simply password protect external hard drive WITHOUT format (it's large and full and I don't have a way to back it up). I also don't want solutions such as VeraCrypt, since you need the software installed to access the drive later on. And I don't want BitLocker, since I want it to be accessible on Linux aswell. I just want a simple pop-up window with a password login dialogue. And no, my external hdd didn't come with a software for that.

Any ideas?

Azure AD, LOB Apps and AAD Connect

Fri, 03/16/2018 - 18:19

We're on the latest version of AAD Connect and actively syncing our on-prem directory users to AAD.

As we start integrating our LOB applications with Azure, I'm seeing a definite need to use SAMAccountName in Azure AD. For instance, our thousands of ServiceNow users had been created manually using their AD SAMAccountName. When we eventually move to Azure Auto-Provisioning, we're limited to using their UPN, which is very different from the user's SAMAccountName. Ex: ABC15021 / We could probably bulk-update their usernames in the application, however that would require someone with REST API programming skills, which we don't have access to. I foresee other LOB applications having the same problem in the future. Since our on-prem ADFS supports SAMAccountName for logon, we'd prefer to continue using that for seamless pass-through authentication.

The only viable solution I see is to sync up a user's SAMAccountName into an available extension attribute with AAD Connect.

Has anyone faced this or have guidance / best practice information? I would also appreciate if anyone has guidance or a tutorial on writing this new sync rule. The whole process is a bit intimidating considering my limited experience on the subject.

The end of Novell

Fri, 03/16/2018 - 18:16

Today is the day. I just shutdown one of our OES eDirectory servers for the last time. The bulk of our services will cut over to Active Directory over the weekend. The rest will follow in the coming months, and by this fall we will no longer have services running on Novell, or MicroFocus, or whatever the hell they're called now. Feels like this

Datacentre storage requirements

Fri, 03/16/2018 - 17:38

Considered posting this over in r/storage, but figure this question is as much about the procurement process as actually about the underlying storage, so others have likely been through the same process.

Basically, we currently have 2 x EMC VNX SANs in primary datacentre location. These provide block storage to a VMWare deployment over iSCSI. Total storage currently is around 80TB and 300VMs (mixed workload - DBs, VDI, fileservers etc), mostly spinning disk.

The maintenance on these comes up for renewal this summer, so I have been tasked with investigating the options and presenting costs back, either to renew maintenance, or replace storage.

I have a few gripes about our current solution, and no particular loyalty to the brand or the var we used at the time:

  1. The solution was spec'd incorrectly at the outset, we ended up with less space than required (partly our bad, partly theirs).
  2. We had a lot of performance issues on initial deployment, again suspect error on part of the VAR, had to redeploy completely before entering production.
  3. The VNXs feel very "closed box". It is hard to see what is going on in terms of performance. Most requests are met with the request to send SP Collects, which then take sometimes over a week to analyse.
  4. The costs to expand and add shelves per GB is extortionate.

In my ideal world, we would replace these SANs with something new which will tick all the boxes, but I need to try and make the figures work in order to justify this. In the ideal world, I guess what we are after is:

  1. Consolidate the two current VNXs into a single iSCSI block storage solution for our virtual environment.
  2. Would like new solution to have significant flash tier for a boost to performance over the current.
  3. Would like to start at around 100-120TB (expecting significant growth in next 6-12)
  4. Good support either from vendor or VAR
  5. Needs to be easy to analyse performance, reporting, bottlenecks etc
  6. Expansion costs need to be reasonable
  7. Ideal world, footprint in rack would be reduced (current solution takes up 1 full rack)

TL;DR, Really I have two questions for you:

  1. Recommendations on which vendors to talk to start scoping this and getting pricing etc. - is it best to approach vendors direct, a particular VAR to recommend, etc? (UK based).

  2. Ideas on the overall approach - how can I best quantify the comparison between replacing and renewing maintenance (to non-technical management).

Private Fiber between (relatively) nearby facilities -- Who to call?

Fri, 03/16/2018 - 17:34

Forgive me, as this may be more of a question for r/networking --

I've recently become an I.T. ManagerTM after a few years as a Sysadmin/network admin. I've never had to purchase my own WAN services before, as that was always handled by the person I just replaced. Anyways... we're acquiring a new facility roughly 2700ft away from our current network hub, and I was wondering about the possibility of connecting them via private fiber rather than paying about $300/mo to bring them into our existing AT&T MPLS.

We currently have another facility on our campus connected that way, but the entire run is within our property. This new run would not be; there'd be two street crossings at minimum. The majority of the run is through residential areas that wouldn't see a lot of digging going on, so I think we'd be relatively safe from backhoe fade.

Have any of you ever had to do something like this? If so, do you have any trusted vendors/construction companies, and do you even think it's worth it? If it helps, we're a municipality (so technically exempt from most permitting requirements) and I generally would have to justify this kind of thing over a 10-year period. I'm just trying to see if I can even make it viable.
