@msff-amman-Itofficer just look at this for quickly provisioning.

@Francesco-Provino

While I understand what your saying, and it is the ''pure way'' its not that I dont want to learn new things, its just I want to be quick at deploying VMs, and having a tool for me is much preferred.

But will try to keep that as an option, I do deal with virsh shell, but in very humble mannor, like Virsh Destroy and list --all and start/shutdown. But down the road I will learn more.

Mmmh, if you want to quickly provision VMs you just have to script it! I have made scripts that creates simple VMs (small, large, etc) with different OSs using <10 lines of bash or python.
It's also very easy to export the xml of a gold master VM and create N new VMs using the master configuration as a template… surely quickly than going through all those gui-based steps!

Libvirt include several tools that automatically install, customize and deploy VMs in a cloud-like way.
For example, in one line of virt-builder you can create ready-to-go VM customizing password, installed packages and many other stuff without look at an install prompt: everything is completely automated.

@msff-amman-Itofficer just use the libvirt shell, virsh! You can both connect to the host via ssh and use virsh installed on the host, or install virsh in the machine you are connecting from and use virsh in a remote fashion.

Virsh can do almost anything you can do with KVM: you can even edit the XML configuration of vm and networks by hand, so really no flexibility limit.
It's also easy scriptable and include a serial remote console, so you can install your OS by hand etc.

If you really really need a graphical console with virsh, you can install any VNC client on your machine and connect to a vm using virsh this way.

View from behind my desk.

Not even a city :D!

Selinux cannot be the problem with SSH, if you haven't changed the SSH server listening port. Selinux has sane defaults for SSH, much less for other application… one of the bigger concern in learning RHEL/CentOS is not how to make everything running, but how to run it with Selinux ENFORCED.

Of course, never disable Selinux. Never.
It's maybe the most valuable security feature on the whole Linux ecosystem.

@scottalanmiller where these appliances used?
In enterprise level only??

No, opposite. Most verge on hobby systems. VyOS is very enterprise, we use it in our big data center. That's shared code with Brocade and Ubiquiti.

pfSense is FreeBSD / pf based and very good. But more or less an enterprise would never build their own firewalls. You buy appliances for that.

What is brocade and ubiquitous words used here??

Brocade and Ubiquiti are firewall vendors. Brocade makes very large enterprise gear like Juniper. Ubiquiti we talk about daily in here. It is nearly the only network gear we recommend for small business any more - it is so good and so cheap that nothing competes with it.

Agree, Ubiquity stuff is good and cheap. You can replace a 3k€ Cisco 5510 with a 400€ ER-8.

Brocade is one of the top player in the networking world. They buy Vyatta and make their own (mostly closed source) version of the Vyatta appliance.

@Tim_G said in Copy file from Windows Server to hosted external CentOS server:

I posted a question similar to this one maybe a couple months ago, either on ML or SW (can't remember, and can't find it!).

Anyways, I'm still at a loss here:

I have an on-prem Windows server (Serv2016) with internet access, but cannot be accessed externally.

I also have a virtual private server (CentOS) hosted with Godaddy, with SSH access. I can connect to it just fine with Putty.

What I'm trying to figure out, is how I can get a file from my on-prem Windows server, to the cloud server, automatically via Scheduled Task?

I'm stuck, and now in a spot where I can work on this some more. But I can't find my previous Post to bring this back into the light and review previous responses.

Of course you can do it directly via SFTP.
Or maybe, create a VPN between the two machines and setup a simple samba server on the CentOS machine and mount it in the windows one.

You can also do the transfer via Rsync (it works on windows).

It'a a simple task and you can do it in many ways, you just have to choose what is a better fit for your needs.

@Tim_G If you need a truly enterprise and FLOSS backup software, just try Bacula or BareOS.

@scottalanmiller said in Where to buy Ubiquiti in Italy:

Pretty simple, need some minor UBNT gear in Italy. ER-X would do, USG might be better. And an entry level AP. No idea where to find them or if you can.

Tagging @Dominica @Francesco-Provino

I took ER and unifi on Amazon, the price was good. There are also resellers on ebay.it, of course, sometimes even cheaper.

@StrongBad said in Salt Minion Problems:

vi is a killer, one wrong key press and anything might happen.

Vim is as precise as a scalpel, don't blame it :D.

Disclaimer: I'm a vi-lover/addicted.

@Romo said in Salt Minion Problems:

So after a full server reboot the salt-minion finally started but it is not properly registering its key to the master correct @WrCombs .

Maybe this happen when you clone an already registered instance.

@WrCombs I suggest you to change the hostnamw via hostnamectl.

What is the output of systemctl status salt-minion?

Thanks everybody for the answers! I'll start to test your suggestions starting from tomorrow :).

@jt1001001 yeah, I got one of those unicomp 7 years ago… it works great, still my main keyboard. Big import taxes US -> Italy, but great feelings!

@WrCombs I just come back from a Dell conference: Latitude 7480 seems to be the new gold standard for business laptops, apart from Lenovo.

You went to a Dell conference and they said the new standard is a Dell laptop. Gee, I wonder why?

No, it was a conference about servers and storage.

One of the Dell people let me try his Latitude, and I say that the new Latitude are very well made.

Yup.

Or, maybe I'm a sysadmin from Italy that suddenly join Dell sales workforce yesterday, and now is trying to sell laptops in the US from Italy.
Seems reasonable, nay?

LOL

@Grey It's just my opinion on what I saw and touch in person, nothing to do with the Dell event.

Frankly, I'm not even interested in buying their servers anymore.

I still think to buy myself a Carbon X1 eventually, but those new Latitude are awesome. Just that.

@scottalanmiller said in CentOS 7 File Server (samba). Do you know easy GUI to manage ?:

Why do you want a GUI? What's the end goal?

I'm guessing his goal is to not have to learn CLI commands.

I'm the captain of that vessel... it's the 21st century, why in the hell would I restrict myself to needing to type letters at a computing system to make it go? Are we cavemen, dragging our knuckles toward the black screen with archaic green letters to type cryptic text commands when GUIs have existed for a couple of decades now? I thought we lived in the future.

No, you are still living in the past.

The future is not even staring at the screen, the future is write a piece of software-procedure once and being able to rebuild a system/correct errors/etc in a completely non-interactive way forever.

The future is being architect drinking mojito in a beach, not click-slaves in a cold rack room.

Actually, if I had to script / CLI everything, I would have zero free time because all my time would be spent poring over scripts and commands to find where the typo is that is fucking the whole thing up. Besides, I have almost no tasks that I do so often that I feel the need to have some script to run it. So speak only for yourself in that regard, not everyone does things like you do, not everyone's job is like yours. I have lots of free time, despite using GUIs.... hmmm, your idea of impossible came true!!!

The future is retirement, drinking a mojito on a beach, with no office to call or report to. Your dream of still working in the future saddens me. What fun would travel be if you had systems to think about? (none, it would be zero fun).

In Italy (I don't know if that apply to US also), we study Aesop's fables at college; one of the most famous, is about an ant and a grasshopper https://en.m.wikipedia.org/wiki/The_Ant_and_the_Grasshopper …

Regarding the time to script manual work, some days ago I wrote a very basic saltstack recipe aimed to create a stateless self-resetting SMB server in a CentOS machine… here is the code (not well organized, not beautiful of course, but it works): https://github.com/theinfiltrated/my-saltStack . I wrote it mainly to learn SaltStack, but the week after I deploy two instances of this stateless SAMBA in two companies just because they were that easy to bring up and they solved two different problems very quickly.

In my work, I do 95+% remotely and sometimes I even spend some of my working day in the beach or other funny places because I can do almost everything remotely with very little bandwidth thanks to the fact I can use CLI. Probably I'm younger than you, but I see many years of work im my future, of course .

Regarding your job: setup a SMB server is something SUPREMELY repetitive and scriptable, as you can see in my github repo.
Othe task I'm pretty sure are parts of your job should be reset a password, install software, update a machine, reboot a vm… but ok, is your job, you can do it in any way you find confortable. But saying that GUI administration is the future, just seems, ehm… weird. Take a look at saltstack or ansible, and think about why the buzzword "devops" is so popular today .
