Hi We thank you very much for your efforts and great achievements. I have a problem I want to solve. I have created another group and want to prevent it from connecting to the whole machine except for one program either through the firewall or through the permissions.
I tried using chmod and removed the execute from the others but the result was as if I removed the execution from the user who is me. What is the solution ? Is there a firewall solution at the software level? what is it ? Is there a solution using permissions? Thank you
