Use showmount to enumerate NFS exports:
showmount -e <target_ip>
Then we can mount NFS shares using mount
mkdir /mnt/nfs
sudo mount -t nfs <target_ip>:<enumerated_share> /mnt/nfs
Useful nmap scripts
nfs-ls #List NFS exports and check permissions
nfs-showmount #Like showmount -e
nfs-statfs #Disk statistics and info from NFS share
