It comes down to security vs. convenience. Performance is something completely different and can be tuned/scheduled.

Do you leave your keys in your vehicles ignition? Do you leave your front door wide open? Do you write your personal identity numbers on your arm?

No? Use anti-virus.

RHEL if support is required, CentOS if I'm being lazy on updates (joke); beginning to just use Fedora Server for everything not requiring support. I will probably start phasing out CentOS.

That's what we are doing. CentOS is nearly gone now. Only required for Zimbra.

Zimbra actually requires CentOS? Can't use FS?

Yes, Zimbra targets LTS releases only

It's a major fail. In the 2000s, they actually did RHEL detection and would barf if you ran CentOS! You had to alter their installer to make it work.

If Zimbra product release notes were to state "we are NEVER going to not require CentOS", and you wanted to use Fedora Server... what email system would you switch to? Not necessarily just for the masses.. just what you personally like when it comes to supported features like calendars, native support for signatures and control over originating format when replying/forwarding (plain text/html) without using 3rd party plugins, etc.

Don't know any enterprise email systems running on Fedora.

Ah, that answers that question. Everything is CentOS, RHEL, IBM, etc?

@nashbrydges said in Synology external access - weird information:

@bbigford I manage 3 separate Synology NAS units for clients, 2 with dynamic IPs and 1 with static IP and the requirements were essentially exactly the same for all 3. Ensure the correct port was directed to the device and DSM just worked. Wonder if your user has missed something.

That's what I'm thinking. I responded a moment before you did with a previous conflict regarding proper PAT. If he would allow me to just log in and do it myself that would cost them less operationally. I typically follow up with reminder emails that if I'm left to do my work with proper access, it costs them less overall. Comes down to a trust issue; it is just going to take time to bust through their ego and allow me to do my job.

@nashbrydges said in Synology external access - weird information:

The default port for DSM for HTTP is 5000 but for HTTPS it's 5001. Could that be the issue you're having?

I'm wondering if the source and destination is backwards that they configured. I had to fix a rsync issue coming from (different port) translated to 22.

I tried both HTTP and HTTPS, wondering if the port was the issue.

@dbeato, thanks...I'm relieved that someone still has working with me on this.

I am building a server now with multiple domains to follow up on this.

Oh... wow... a FOSS product would puke if you weren't using paid OS support? That's just overall very weird.

Short back story: New setup with existing hardware. Synology appliances rsyncing between main site and offsite at one of the partner's houses. New client had brought an appliance back onsite after firing a previous provider for not verifying backups and there was a disaster. After assessing things, their appliance hadn't synced for months. Delta copy was around 3TB. After a week of copying, I sent it offsite and have been verifying the sync weekly (things are healthy and performing very well). I am going to be redoing this offsite solution when the appliance ages out in the next couple years. Risk mitigation and overall sync performance has been assessed compared to cost of redoing things during all of this.

I need to reach the appliance to be able to update the DSM firmware; ensuring both appliances are on the same firmware as well as just making sure software is generally up to date. I was looking up some tidbits on Synology external access as https://external:50XX using PAT to 5000 on the appliance is being setup using the owner's AiO edge appliance. Not using DDNS, there is a static IP on the resident's home for offsite backups. Can't reach the device, but the partner did set it up himself as he is a power user and it's tough to get him agree to let people do things for him, even though it actually costs less operationally to just let me get in and do it rather than provide details on what is needed. That aside...

First forum I hit... does anyone else find some of the information in the comments very odd? ISP blocking port 80... Synology using too many ports to be able to do PAT... DMZ setup being in a AiO user manual, as if it is just a standard home configuration for every use case...

@dbeato
Wow! You are one of the gems which has set it up correctly.

How? How? How?

Just curious, but why are you going back to in house for your site? There are many good ones out there, it sounds like you're just on one that isn't performing very well for what you need.

What are most people using as a backup system for KVM? I've mostly just used StorageCraft and Veeam for Hyper-V and VMware.

@tim_g said in Nested virtualization - lab:

I have done it quite a bit on HyperV and KVM. Both were good.

Hyper-V I'm guessing it was in 2016? 2012R2 was nearly unusable.

I'm building a new beefy lab workstation. I considered getting some used servers, but doing some nested virtualization has worked out in the past and is going to carry a lower cost for what I'm doing. It's strictly for the purpose of working with HA.

I've virtualized some hosts with VMware, and have heard that Hyper-V Server 2016 now supports nested virtualization whereas 2012R2 had some issues. I haven't tried it though.

Has anyone tried nested virtualization with KVM, Xen, or Windows Server 2016?

@jaredbusch said in Hypervisor preference - costs included:

All of my clients are on Hyper-V.

I am running my home lab on KVM now, it was Hyper-V.

Why the switch in lab but not production? Do your clients require paid support, or are you still familiarizing yourself with KVM to where you're just not ready to put it in production?

Found it. You have to share the site to any users first, before that option shows up. Just sharing documents doesn't actually generate that option. So once you share a document, it's shared. That option isn't for shared out documents, it's for the site itself.
