I added a header into the main topic list for that. But it is going to be later in the Advanced Topics, section. Oddly, I know of pretty much no standard Linux Administration tomes that cover DRBD. It's so core, very odd that it so often gets missed.

Could it be that most Linux Admin's don't know about it until they go searching for it? ...That's how I found out about it.

You would hope that the people writing the books would know, though!

Seems like the totally free of NextCloud is a pretty big factor. Most of us have pretty tight budgets, so being able to totally demo and test and even deploy NextCloud without further approval is great.

Man that is tiny. And the $9 upgrade looks really nice.

Dropbox seems logical. Simple, not expensive, and doesn't require the customer to run an entire server just for this one little thing that probably doesn't happen that often.

that's pretty fishy. What is responding on that port, then?

@coliver I know, I wasn't even included in the conversation at the time when we migrated to O365, and I wasn't included in the conversation when they setup Hyper-V.

Nor was I included when they built this VM, or the other reporting VM on Hyper-V to which 16GB of memory and 2 cores assigned to it...

Honestly we gave up with SfB it was too laggy and crashed often it also didn't transition between desktops and cell phones well (didn't get all messages at the same time across both). So we jumped ship and went back to regular skype which is far better for screen sharing, presenting etc. (not that it is the greatest either).

@Mike-Davis have you noticed any new features have appears that should not be there in the E1 version?

Good article. There is ZERO reason to have a GUI on a Domain Controller. Everything can be done through Server Manager on Windows 10/8

You mean RSAT 😉

Both? You can do a lot of directory management through Server Manager as well.

Ok, agree. Just don't like the Server Manager this much, ugly interface. I want to be sure WHICH drive on WHICH host I'm going to format for example. But that is just my personal opinion and I'm more or less a console fetishist 😉

But when it comes to ADSIedit or AD sites, you really want to have RSAT.

huh?

Those options are generally only there is RSAT is installed.

Well I've eliminated 7 servers, down to 2 servers in a HA pool...

And in the process of doing that I've consolidated all of the network shares dispersed across those 7 servers into a single VM.

Making backup via Shadow Protect and XO far more straight forward..

There is no simple way to know this. If he sets up a machine that will listen on every port, he could then test with a port scanner from internal.

Good way to get written up if they don't have permission as well.

I think "getting around the rules" is already assumed at this point.

Wouldn't mind to do any port scanning. A good admin will see this, and there is probably a reason your friends net is locked down. Scanning the network can get his butt faster on the street than he can write pcap.

Anyway, just for educational purposes: Use SSH port forwarding, maybe to a host at your friends home.

This will route every traffic to the desired target through an encrypted tunnel. You may bypass most firewalls by using common ports this way. A bit hard to explain, but there are plenty of tutorials available.

But you mentioned tcp/8080. That port is often used as a HTTP proxy, so your friend probably does not have a direct (routed) connection to the internet at all.

DDoS depends on public addresses acting as a clients pounding your DNS server with thousands of recursive queries at once. If your DNS server isn't public, then it isn't a open resolver, and a client on the internet can't query it directly.

In our case, we have a local DNS server, available to the internet, as a backup to our ISP-hosted DNS. This server is typically vulnerable. But it's set with a higher cost so it won't be used unless ISP goes down.

@halizard Awesome, I'll have to give it a whirl.

I assume that there is only one partition. You can check yours but there should not be multiple partitions.

This is how XS7 sets it up, at least...
