nfsd

TLDR

Start NFS server

$ sudo systemctl start nfs-server

Enable at boot

$ sudo systemctl enable nfs-server

Restart NFS services

$ sudo systemctl restart nfs-server

Check status

$ sudo systemctl status nfs-server

Manually start nfsd

$ sudo rpc.nfsd [8]

nfsd (NFS server daemon) handles NFS requests from clients. It implements the NFS protocol to share filesystems over the network.
The number of threads determines how many concurrent requests can be handled.

PARAMETERS

nprocs

Number of server threads.

-d, --debug

Debug mode.

-p, --port port

NFS port.

-N, --no-nfs-version ver

Disable NFS version.

-V, --nfs-version ver

Enable NFS version.

CONFIGURATION

$ /etc/exports              - Exported filesystems
/etc/nfs.conf            - NFS configuration
/etc/default/nfs-kernel-server  # Debian

EXPORTS FORMAT

$ # /etc/exports
/home 192.168.1.0/24(rw,sync,no_root_squash)
/data *(ro,sync)

CAVEATS

Requires rpcbind. Firewall must allow NFS ports. NFSv4 uses single port (2049). Security through exports and Kerberos.

HISTORY

NFS was developed at Sun Microsystems by a team led by Russel Sandberg in 1984, becoming a foundational Unix network protocol.
