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 |
