To set up NFS share on Debian, you can use the following steps: Install the NFS server package by running the command “sudo apt-get install nfs-kernel-server.” Create a directory to be shared with NFS by running the command “sudo mkdir /shared_folder.” Set the permissions and ownership of the shared folder by running the command “sudo chmod -R 777 /shared_folder” and “sudo chown nobody:nogroup /shared_folder.” Edit the exports file by running the command “sudo nano /etc/exports” and add the following line: “/shared_folder *(rw, sync,no_subtree_check).” Restart the NFS server by running the command “sudo systemctl restart nfs-kernel-server.”
