@black3dynamite said in Ansible facts nested variable syntax preference: Looks like Bracket notation is best choice instead of dot. Bracket notation always works. Dot notation can cause problems because some keys collide with attributes and methods of python dictionaries. Use bracket notation if you use keys which start and end with two underscores (which are reserved for special meanings in python) or are any of the known public attributes: Overlooked that in the documentation. While it's less efficient to type [' and '] rather than ., I'll live with it.

@Obsolesce said in YAML terminology and Ansible: @Pete-S said in YAML terminology and Ansible: @Obsolesce said in YAML terminology and Ansible: @Pete-S said in YAML terminology and Ansible: Other than that it doesn't matter to me what anyone calls it. You are 100% to call it whatever you want. But a key/value pair is commonly referred to as a dictionary... or a hash table which is a dictionary data type. This isn't exclusive to Python in the least. "Commonly referred" depends on the programming language in question. For example in many other languages it's commonly called an array or collection and never a dictionary. If you look at the part you quoted, YAML calls it mappings. The proper computer science terminology would be associative array. https://en.wikipedia.org/wiki/Associative_array The best thing to do is to call it exactly what the language or software you are referring to calls it. If Ansible wants you to create what it has named in their documentation as a dictionary in YAML, that's what you refer to it as. Otherwise, someone who is familiar with Ansible and it's documentation won't know what the hell you are talking about if you call it your own thing. I can agree with that point of view - YAML in the context of Ansible. https://docs.ansible.com/ansible/latest/reference_appendices/YAMLSyntax.html So you'd call it dictionaries then. And lists.

@scottalanmiller said in New to Linux Administration: RHEL-Based or Debian-Based OS: I agree, both is the obvious choice. But to truly answer the question, I'd focus on Ubuntu (not Debian) and then RHEL. Debian is great, but it is Ubuntu specifically that has the market. Yes, almost the same is never the same as exactly the same.

@Pete-S said in YouTube Month in Review: December 2020: @EddieJennings Impressive work Eddie! Thanks

@EddieJennings said in Script for Creating VMs from Template VM in KVM: @travisdh1 said in Script for Creating VMs from Template VM in KVM: @EddieJennings said in Script for Creating VMs from Template VM in KVM: @Pete-S said in Script for Creating VMs from Template VM in KVM: Not the exactly the same thing but you might want to look into how to create a VM from scratch. Meaning a script that will set up a VM with vCPU, memory, storage, network etc and then boot it from iso and have it do an unattended install, create what users you want and install the packages you need. That's one of the next things I'm looking into. @EddieJennings Also remember about things like kickstart in RedHat based operating systems. In Fedora/CentOS/RHOS you can use a kickstart file to automatically select all the install time options for the OS. A short time later you've got a fresh server and all the time it took you to setup was running the creation script on your hypervisor. One of the things I'll need to figure out going the Kickstart route is setting the hostname what I want it to be at the time of installation. Likely not difficult to do, I just have to figure it out. Or perhaps, I can just truly take the approach of just making a clean minimal install, and then later configure to whatever specific thing I'm wanting the VM to do for my lab / testing. Inside the kickstart file you'll find something like this: network --hostname=centos8-4.example.com We use debian as our goto and then it's called a preseed file. The only real thing that can be tricky is to tell the installation what kickstart/preseed file you want to use. You can do it in different ways. If you don't want to rely on dhcp/tftp/pxe etc you can roll your own iso file. I think the kickstart file can also be mounted as a drive that the installation will detect when it starts. I think the best approach is to make an automated installation with same basic settings and some of those will get changed later in the installation. For example you can use a fixed hostname that is later changed from ansible.

@Dashrender said in Managing Distribution Groups in an Exchange Hybrid Environment: @EddieJennings said in Managing Distribution Groups in an Exchange Hybrid Environment: I ought to have clarified. DUO MFA comes into play with Outlook for our mailboxes that are in Exchange Online. On-prem mailboxes (the few we have left aren't subject to DUO). Are those that are left on prem - are they actual users? If so, I'm curious why they can't be migrated? Eventually all users will be migrated, so, yes, we still have real users on-prem. This is outside the scope of the original question / scenario, but I've learned a good bit during this process with much of that learning validating a few things I already knew, such as the value of taking the necessary time to plan, and prep the environment for migration (removing unnecessary objects, etc.).

@travisdh1 said in YouTube Months in Review: July and August 2020: @EddieJennings You've been busy! That I have. I didn't do a practice session for every objective because I ran out of time before the test. But taking the time to talk through most of them was a good way for me to determine if I needed to go back and review details.

@IRJ Shamelessly stole your ideas and tweaked the wording a bit. Draft 5 @Pete-S I'll look at drafting the other format over the next couple of days. If I come up with anything decent, I'll add it to this thread.

@jmoore said in YouTube Month in Review: June 2020: @EddieJennings Good info thanks eddie! You're welcome. My RHCSA videos are truly "practice sessions" for me, but the information should be accurate.

@Dashrender said in Exchange Online ActiveSync Organization Setting Effect: So you have to then manually approve them? You can create rules that would allow devices and such, but, for right now, On-High wants everything quarantined and then manually approved. So specific to your question: "yes"

@EddieJennings said in MacVTap Modes: One option I didn't see in the redhat doc was openvswitch. Don't they support it? The link I posted was for RHEL 6. I just now saw that RHEL 8's documentation is online. I glanced through it and didn't see that mentioned. I'll read it more closely tomorrow. https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/configuring_and_managing_virtualization/configuring-virtual-machine-network-connections_configuring-and-managing-virtualization There's no mention of openvswitch anywhere in that document. I am aware of XenServer and XCP-ng uses it by default. So its possible RHEL just prefers using macvlan/macvtap instead of openvswitch.

@scottalanmiller said in MangoCon 2020 and COVID-19: @pchiodo is going to post in the morning the details. Obviously we are still under lockdown here, so no one is traveling here. Texas might be open, but Dallas County is not. We've spoken to the venue and we have a postponement at this point without a date. Paul will give all the details tomorrow. Excellent. I look forward to seeing the plan.

@JaredBusch said in MangoCon 2020 Hotel Details: @EddieJennings said in MangoCon 2020 Hotel Details: Don't be tempted to stay at Holiday Inn Las Colinas. It's a bit of a walk That is not walkable unless you like to take significant risks I did it last year, but won't again now that I know the length of the walk.

I like the idea of the web application firewall, and that looks like something that can setup on the same VM as what would be running Nextcloud, etc.

Mystery solved.

@notverypunny said in Enterprise IT community: Don't know if we qualify as enterprise, but communities like this help get an external perspective regardless of the size of the organization. The challenge I find in larger orgs is the inertia involved in anything IT. Almost in the literal sense as far as trying to get something started but also in trying to halt / redirect a project that's heading for a bad outcome. In an actual enterprise, I would suspect that only the management team of IT could have much real impact on a project going a bad direction. And again, it's getting those in management to have buy-in before anything would change.

So how we did it the last place I worked. We used a mix of X2Go, X-11 forwarding/MobaXTerm, and RDP. It depended on the user as to how they wanted to do it. RDP gave them a full desktop since X2Go couldn't any longer on GNOME 3. X2Go gave them just applications from a menu to pick. People who were used to the cli used X-11 forwarding because it's what they were used to.

@JaredBusch I understand, I just close the annoying dialog and go on.

Bit of a necro post, but I'm finally getting back around to NFS review for RHCSA. nfsstat -s tells me I'm using version 4.
