Hi everyone,
I set up a ubuntu server (running ubuntu desktop) connected to about 15 pcs using samba. All going good for a month now. I never set up any users or groups (not sure how).
Today one of my colleague said he needs to make one of the pc's not accessible to the server.
Can anyone please help on how to do this?
Also I like to know how to setup users and groups too (im assuming this might be necessary to solve my question too?)
I am assuming that you do not want a particular PC to access samba share on this particular server. If that is the case you can block the communication from that particular system's IP address on port 137 (UDP),138 (UDP), 139 (UDP) and 445 (tcp). If you do not want this machine to talk to your Ubuntu server at all then you can configure the UFW to reject any packet received from this machine.
For setting up samba users and groups the following links will help you out:
