Samba

In this video I go over two quick and easy ways to set up Samba shares in Linux.

So let's start this out.

If you're running Ubuntu or the Nautilus file manager, it is the easy way to actually share something.

We want to install that service.

And install.

So this installs the Samba package, and then also any sharing service that needs to be done.

Okay, with that complete, we can go and say, hey, how do we want to limit this share? I want to do guest access, so anybody on my network should be able to access this share quick and easy.

and if you want others to create or delete files in the folder giving them right privileges click this and it will allow them to add and subtract files so we'll go ahead and hit create share and add permissions automatically would add these one second i don't want to do this quite to my dropbox folder so i'm going to hit cancel Okay, let's say I wanted to share this AMD GPU Pro folder.

Exactly.

And on Linux, we've traditionally used Samba for that, which runs nice and safely in user space.

Well,

to understand the shift to KSMBD, you really have to look at the penalty of a contact switch.

Okay, break that down for us.

If you run Samba in user space, meaning ring three on a CPU architecture, every single time a user opens a file, reads a byte, or writes data, the CPU actually has to pause.

It has to save its current state, flush certain caches, cross the boundary into ring zero kernel space to execute the disk read, and then cross all the way back to hand the data to Samba.

Which, I mean, that might sound fast to a human.

Yeah.

okay so we also need to look see this numbers matter if give you the lot of information based upon that you can take a next step so this this all zero MAC address here you can see zero zero zero is coming is a normal for SMB only next Samba only next

okay

which isn't tied to a real network interface for the net bios so we can skip this one this information is just a information nothing else

Yes.

And SMB also comes with the username and password.

So if there is no username and password defined to access the resource shared by the SMB server, Samba server, then I will ask team to authenticate that port and the services.

Okay.
