Network sharing between specific systems

[lemming3k]

Hi,
I'm looking for some networking advice. I'm trying to figure out how to set up sharing on a home network, but specificially between certain machines only. I also have the added complication of running different O/S on the machines.

Systems are as follows;

PC A - Ubuntu O/S
PC B - Windows 10 Home
Other Windows PCs on network but not involved in sharing

Desired setup;

PC A to have full access to PC B - essentially this is for file backups I want to push down to it.
PC A to not be accessible to any PCs - for security reasons I only want one-way transfers, and no other access (not even read-only or list).
PC B to not be accessible to any other PCs but A - Other PCs are not owned by me, so should have no access to anything (again not even list or read-only). Unfortunately it's a shared network so I'm looking at ways to firewall/subdivide this in some way.


It's not something I've ever had to look at before or too knowledgable on. The only thing I can think of is using some kind of folder permissions similar to workplace AD setups, but with my particularly versions and different O/S setup I'm not sure it's possible.

It is possible it's just file sharing. All Operating systems supports it between versions.

Thank you. I wasn't sure how ubuntu and MS would interact with each other.
Have I got this right then that it's just a case of adding the user account for A to the files on B, and then removing any general "all users" type access on those files so nobody else can see them? Someone once showed me a c$ backdoor onto peoples systems if you know the PC name - is it possible to prevent that as well?

Yeh but that’s not by default and you still need to set correct permissions.

Just right click folders and set permissions to a certain user as full control then authenticate.

\\hostname.or.ipaddress\share
Username
Password

Should world straight away. Firewall mig hot need to be setup for file sharing to allow though.

Thank you. I honestly thought it would be far more painful, at least to keep others out! Will see how it goes this weekend.
