NFS

Networking/Protocols/NFS

NFS on Linux is typically provided by nfs-kernel-server (server) and nfs-common (client utilities).

Install (Server)

$ sudo apt install nfs-kernel-server -y

Server Status

$ systemctl status nfs-kernel-server

Configuration

NFS is configured via /etc/exports, which defines shared directories and access rights. Common export options:

Option	Description
`rw`	Read and write access
`ro`	Read-only access
`no_root_squash`	Root on the client keeps root privileges
`root_squash`	Root on the client is mapped to a normal user
`sync`	Write changes to disk before completing requests
`async`	Reply before changes are committed (faster, less safe)

Create an Export

$ mkdir -p /home/cry0l1t3/nfs_sharing
$ echo '/home/cry0l1t3/nfs_sharing hostname(rw,sync,root_squash)' | sudo tee -a /etc/exports
$ sudo exportfs -ra
$ sudo exportfs -v

Mount an Export (Client)

$ mkdir -p ~/target_nfs
$ sudo mount -t nfs 10.129.12.17:/home/john/dev_scripts ~/target_nfs
$ tree ~/target_nfs
