NFS

Introduction

• Network File System (NFS) is a network file system developed by Sun Microsystems and has the same purpose as SMB.

• Its purpose is to access file systems over a network as if they were local. However, it uses an entirely different protocol.

• NFS' default port is 2049 TCP

Basic Enumeration & Interaction

• When footprinting NFS, the TCP ports 111 and 2049 are essential.

• We can also get information about the NFS service and the host via RPC (2049)

Command	Description
Use nmap scripts to find connected NFS shares names	sudo nmap --script nfs* <IP> -sV -p111,2049
Show Available shares on target IP	showmount -e <IP>
Mount (locally) an available share	sudo mount -t nfs <IP>:/target-NFS/ /your-target-dir -o nolock
Unmount a previously mounted share	sudo umount ./target-dir
