s your setup is Cloudflare proxy -> Nginx proxy -> apache (mattermost)?

CF Proxy > Nginx Proxy > Mattermost (MM is its own server)

And yes, if I disable the CF Proxy, it works.

Why the double reverse proxies?

That's the standard. You are always expected to have your node.js servers behind a reverse proxy. And CloudFlare is the CDN cache in front. This is the universal standard for all web servers. Plenty of times to avoid it, of course, but this is the baseline system design.

In this case, MM is a raw node server so has none of the protections or handling of a system like Nginx. Nginx also provides the ability to have multiple sites behind one IP address. MM doesn't do that on its own, nor does CloudFlare. No different than how MangoLassi is on NodeBB, also a node platform, behind Nginx, behind CloudFlare.

CF can't do the details port and IP handling, Nginx can't do the globally distributed cache.

Thanks for the clarification Scott. I (wrongly) thought that Cloudflare was a full featured proxy and could do the same job as haproxy, nginx etc.

The virtualization... do we only count hypervisors, or do we count the VMs? Or only the VMs? My desktop has full VMs that are used as if they are completely separate machines. How do we count them?

How do we count VDI, Terminal Servers, Thin Clients, etc?

I've seen that a lot. When I import Drupal databases, I learnt to use its Backup and Migrate module instead, it works flawlessly. Downside is you need to do clean Drupal installation first, but that basically is just creating blank database and putting brick on enter key.

@Dashrender said in Compare Azure to Windows On Prem for Normal Business Workloads:

Hosting Costs
1U Colocation America, /24 IP Range
Monthly cost: ~$250/month
Yearly cost: 12 x 250 = $3000
5 year cost: 5 x $3000 = $15K

Last I looked, 1U was more like $225 with that many IPs. And I think typically you'd get fewer for a lot less cost and/or go IPv6. /24 is two IPs per VM. No need to pay for that.

Yes, the basic 1U was $100 with two power outlets and then you get four usable IPv4s.

A smaller server, say 16c EPYC, 128GB RAM, 2x500GB SSD, would be about $3500 and something even smaller, like a 8c Xeon @ 3.7Ghz, 64GB RAM, 2x500GB SSD around $2K.

So you could scale down everything substantially if you wanted. But if all you are doing is running a few very small workloads then a couple of $5 Vultr VM would be cheaper.

another factor is - are you running windows VMs, likely always cheaper to have your own hardware, but yeah, the amount of workloads definitely plays a factor here.

That's true, Windows workloads make cloud computing harder to justify. Not much, but a little.

@Pete-S said in How to Rename a Column in SQLite Database:

There used to be a lot of databases like SQLite. Often called database engines. dBase was probably one of the first.
Later Microsoft Jet engine (aka Microsoft Access) became popular when Visual Basic ruled the world.
Basically it's a one user database. You can have more than one user but it's done by multiple users accessing the same database file.

Or by having an application on top that accessing the file and shares it out. That thing can be called a "database management system" or any application, really.

All databases use database engines. MySQL, for example, isn't a database. It's a database management system. It uses one or more database engines to talk to the files on disk. MyISAM and InnoDB are two database engine options for the MySQL platform.

At the end of the day, all databases work like SQlite. You can easily build your own database management system that uses SQlite as the engine and it could work just like MySQL or Oracle or SQL Server. Those are all single users to a file, under the hood. They just have the "multi-access" management built into an extra layer, instead of letting an application handle it.

But for most things, you only access a database from a single app anyway, so that extra layer is often unnecessary as it is redundant. Just adds overhead.

@Dashrender I concur about the Networking Essentials material. Good then and lot of it still relevant today. 😉

Here it is

This is the error:
a8ab3c57-38bf-4d0f-ad9a-07476b021268-image.png

Check if the error is present by by visiting Help-> About Avimark.

If you confirm the error is showing follow the steps:

Close Avimark

Find the Avimark shortcut in the desktop, right click and open its properties.

In the target section add /regserver to the Avimark link and click ok to save the change.

Right click on the Avimark shortcut and run it as an ADMINISTRATOR
a1e9393a-0e31-46e1-9dd4-f41b82d5123a-image.png

Let it run for a bit (1-2 min), nothing will appear to be happening but it really is.

Right click the shortcut again, go into properties and remove the added /regserver to the target field (returning the shortcut to the original state).

Open up Avimark again and the error should be gone and the machine will be printing again.

@scottalanmiller I haven't used them, but from what I hear it's only network storage. I could easily build something that would be faster for less money.

I recommend the Remmina RDP client tool, it's the bomb.

I love Remmina as a client.

Oh Cool! Thanks Scott!

I like your 53 mins intros, but that said you cover and reach all the important parts. I wonder what will be deep dive session how long will that video be.

@wrx7m said in VMware Host Cannot Connect from vSphere Client:

Could also be an issue if a vendor-specific ISO was used to initially install ESXi. I ran into a similar problem with Dell; I had to get the Dell ISO from their downloads for the specific server model/service tag.

For 6.0 this is fine (you'll use this to get ASNC drivers). You can also add the dell VIB depot to get them this way also.
For 6.7 Dell has (thankfully) stopped shipping ASYNC drivers and moved 100% to inbox. It's all for 3rd party management VIBs. Honestly I've seen 3rd party VIBs be a culprit for updates before. I'd make sure you are updating the BIOS/FIrmware also when updating ESXi (People forget this sometimes).

I've already used this guide again. LOL, boy this is handy.

@Romo yeah, we want that. The MC Router is Windows only, so not very useful as there isn't any Windows involved 😉

@Dashrender said in Comparing a Small Server and a Printer:

The waiting for a response on those LCDs and on the web interface I'm assuming are CPU/RAM bound.

Web, maybe. LCD very unlikely. Can't be RAM bound, if that was a case you'd need swap space but printers don't have hard drives and swap space. So RAM is either enough or not enough, not fast or slow like a desktop.

CPU is possible, but displaying an LCD screen at full speed is trivial for a 486 or an M68000. So it's safe to assume that that is no the case. Web? Possible. But does the web interface impact using the product?
