Linux Domain Controller

@coliver

Sorry never tried this before.

My result was forewalld.noarch 0.3.9-11.e.17 @base

So the CentOS firewall is installed, but it won't run, or it is running and dropping traffic. Can you try:

firewall-cmd --state

It should return running, not running, or command not found.

With Centos 7, I believe you should be using "systemctrl" instead of "service".

sudo systemctl enable firewalld
sudo systemctl start firewalld
sudo systemctl status firewalld

Yep it will redirect the service commands but it's depreciated.

@coliver

State is definitely not running.

Sparkum

Well for some reason when I got home and started to re-try everything after confirming the service was indeed stopped, suddenly I could start it, and complete step 8 with success....

Still not a DC but progress for sure

Sparkum

So at this point I would have to assume that there is a mistake in on smb.conf file eh?

Just going through the checklist

Installed samba ....... Yep
smb.conf file .........Prob?
Made samba/anonymous.....yep
Firewall steps........yep

Can access it from windows comp.......No
See it in my domain......No

Sparkum

Here is some of my global and share; I'm assuming this is esentially the most important data

I don't think you have an eth0 interface. At least not from the previous screenshot. I believe your interface is called ens33. Although I could be mistaken. Also your hosts allow option isn't going to let your workstation connect to it as it isn't in one of those subnets.

Sparkum

@coliver

Adjusted.

hosts allow is still going to block anything coming from the public internet. Unless you have a VPN setup between your Samba server and the workstation then you will need to change that to accept the public IP address of the workstation.

@coliver

Oh thats a shame, my ISP doesnt allow dedicated IP's on home networks.

guess I'll have to stay on top of this one.

I wonder if I can use one of cloudflare's ip updaters in conjunction with this?

scottalanmiller

That's where a VPN like Pertino is handy.

Dashrender

Did I miss the part where you tried to actually join the SAMBA server to the domain to make it a DC?

As Scott mentioned you'll want to do this over a VPN like Pertino, you definitely don't want to open ports 135, etc to the world on both sides (at C@C and at home) to make this work, which you'd be required to do if you don't use VPN.

Sparkum

@Dashrender

Haha its funny I actually came on here to say "At what point am I prompted to join this to the domain" seemed like all I was doing was making a file share so far.

So to use Pertino for example I would need the VPN on every machine I assume?

I guess my initial plan here is mail server (or SMTP relay even) in the cloud, backup DC (this) in the cloud, dc at home then all my computers and servers, so I would need everything that I want to have access to the cloud DC to have the VPN correct?

Anyone know of any free options for 10-15 computers? (even under 10)

Thanks

Pertino is a full matrix VPN. So every machine that needs to talk to any other machine needs to be on it. This is a limitation, to be sure, compared to site to site VPNs, but it is also its power. It's also known as "software defined networking" and it turns your machines hosted here and there, your independent cloud nodes, your laptops, your desktops, no matter where they are into a single LAN that can all see each other, all the time.

NTG uses Pertino to turn our people around the world and our datacenters all over the world (US, Netherlands and Canada) into a single network. It's like we are all sitting in the same room, even when we are traveling.

You'd have to build your own using a tool like OpenVPN. We've done that before. Can work well but gets cumbersome.

Sparkum

@scottalanmiller

For sure I see the benefit don't get me wrong but I'm trying to cut fees with this not add them (again just a simple homelab wanting to expand knowledge and reach)

And I was thinking OpenVPN last night so I'll keep looking down that route.
Thanks.

I'll try to get the VPN going this weekend and then hopefully start tackling the DC again Monday/Tuesday.

OpenVPN has more overhead, It's great for Roadwarior but I've never used it for site-site connections.

Same here. We used it for hub and spoke designs which are typically better for AD situations. He's looking at cloud servers which are not sites, but end points. So OpenVPN works really well.

IPSec is definitely lower overhead when available.

Tinc is a pretty neat mesh VPN which has less overhead.
You really want all static IPs for it though.
