NFS - Network File Sharing (install server)
install nfs-server
sudo apt-get install nfs-kernel-server
sudo mkdir FolderName (root) umask = 0022 / permissions = 755 sudo chmod 777 file1
Create local settings such as ...
POSIX permissions (owner and group)
The most restrictive combo of Local and NFS permissions is what applies. If a folder has full permissions locally (777) but I export that folder as (ro) instead if (rw), My actual permissions are read-only.
cat /etc/exports sudo nano /etc/exports (add the following lines) /dir/FolderName1 192.168.1.7/255.255.255.0(rw,sync) /dir/FolderName2 x.x.x.x/x.x.x.x(ro,sync)
Export the file system
sudo exportfs -a
Restart the NFS daemon
sudo /etc/init.d/nfs-kernel-server restart
NFS - Network File Sharing (install client)
Install client tools for mounting NFS file system
sudo apt-get install nfs-common
sudo mount -t nfs4 -o proto=tcp,port=2049 RemoteHostIP:/dir/ShareName LocalFolder (LocalFolder on client)
