Any distro with a light desktop. Linux per se is not really memory hungry. Try lxqt/lxde.

@kelly sudo su lets you load part of the root env if I remember correctly.
Basically sudo lets your user do privileged work.
Sudo su lets your user become root. And then ezecute code as root.
This not the same as logging as root but some of the env should be loaded.

@dustinb3403 said in CUPS and Canon Fiery Print Driver:

OK so what am I missing here, I go into CUPS, setup up the printer using the Fiery server and nothing ever prints.

Should I just setup the printer as an IPPS printer?

Ipp is usually the simpliest solution also if you plan to serve the printer consider cups can do pass thru leaving drivers to the client

@lj said in Microsoft Hyper-V server 2016 and RD1000 backup:

I installed Altaro VM Backup and it recognized the RD1000 and backed up to it. I can backup VMs to the RD1000 but not the host itself. I don't think that will be too big a problem so I consider this issue solved. Next issue: Altaro free vs. Veeam free.

Altaro free just 2 vm. Veeam free no scheduling must backup supervised.

In any case both they are a no go. IMHO.

I've used in the past a specific tool from google to upload a pst on gmail. It works great. I've just to find it out again...

Here it is

@dustinb3403 said in KVM Virtual Machine Boot Order:

@obsolesce that's annoying. . .

Edit: still annoying but doesn't Hyper-V have startup priority?

No it hasnt until I checked 6 months ago. Only way is build a delay schema by hand and assign delays to VM batch start them in layers

Hyper-V had startup priority since 2012... fully configurable... startup action and startup delay.

You mean you can use action to wait for another vm to be up and running? If so I ignored it. Delay is mostly a workaround as no one really knows when a dependency will be ready!

This veeam cloud stuff is one of the reasons I gone with altaro (they have azure blob storage)

@irj we have seeweb in italy. Never tried them but they are renowed as a good trusted company here.

@romo unfortunately the free one has not CBT

@emad-r actually The main benefit of containers is to disconnect sysadmin and devel work.
Docker has a very mature environment where a lot of stuff can be easily rebuilt with a few hooks in github or similar.
Sys admin installs and manages the underlying os and the developer can upgrade the runtime as he needs in a disconnected way without minding about sysadmin and viceversa.
Also containers should be os agnostic (as long as compatible docker versions are used).
Just remind that docker is live a live distro. Persistent data are not moved with the container: you need SAN like storsge between 2 docker nodes to reload the same data. And this SAN like storage must be mounted in the same path.

The only linux technology which involves containers and acts as a proper virtualization layer afaik is lxd. I don't know if there is anything similar, aka, another frontend to lxc, the actual userspace driver for kernel isolation technologies.
Of course there is the long standing openvz, but I'm considering some in-tree technology which doens't require a custom kernel.

@Emad-R if you focus on docker just condider it as a way for developers for packaging their apps and runtimes. No other usage is actually envisionable imho.

LXD or similar is a different topic: they are "real" containers.

Not really. Containers are virtualization like any other, they've been around for decades and the idea that they were anything for developers is an extremely recent use case of only a very specific subset of containers. Most containers, and most of the history of containers, don't do anything like that, no more than any other kind of virtualization.

Yes but I think here we are talking docker. Docker is like python virtual envs for anything and not just for python. This is their main meaning to me.

Sure, if we are talking Docker and not talking Containerization, then Docker just seems like a sloppy, error prone way to do that.

My biggest issue with Docker is that it seems to make things worse rather than better. More complexity, more things to break, more dependencies. It introduces the very problems it claims to solve, problems that we weren't experiencing previously.

100% agree. It makes sense only in a developers world no sysadmin usefulness here.

It does that, it does create more complexity at first.

Installing an app for us is much easier, like PHP-FPM + apache, it is only 10 commands or something, however if you did in docker/container in VPS you get the extra benefit of having clean environment in the host OS always + the container can be moved around easily to another VPS + it is much easier for non smart people to get your app and its updates + Docker provides free accout to publish one app.

Also the performance aspect is very good, but the storing this is bad abit.

The key idea here it is not currently hyper visor replacement, it is complementary tool that is good when you have service/server that does not need to store data.

While I find useful to have a package+config easily moveable I would syggest to manage staless services with ansible/salt and their playbooks if you want automation at sysadmin level.

The only pro of docker as a sysadmin tool is you have a good ecosystem with a lot of automation already done. With ansible/salt I don't know if you can pick from repos or you need to write everything from scratch.

@obsolesce said in Outlook 2016 Export to PST Missing a Lot of Data:

You can right-click on the mailbox, or a folder, and in properties, you can see how much data is there versus on the Exchange server.

Most is there, for sure. But definitely not "all".

Confirm. I got always this end result. This is just best effort. Not complete at all.

As a general rule you should open secured sessions on demand. Site to site is not ondemand

I mean: if file were exchanged by https ondemand sessions no propagation was possible.

@scottalanmiller said in Check my 2 min audio theory on Containers:

Containers use shared kernels by definition, that's what makes it a container.

This isn't really how Docker works. Docker manages namespaces. If you use "FROM Alpine" then it will share the kernel, but if you write an app in Go and use "FROM scratch" it has zero reliance on a specific kernel. You can also run full VMs in a Docker container which is how Red Hat uses OpenShift to deploy OpenStack VMs.

Well go requires the kernel too. But yes for the most is the "from scratch" part which allows more abstraction

@Emad-R just to go back on topic: do not confuse snaps or lxd with docker. Docker is mostly for developers who do not package their apps.
