Port 2049

Q: What is port 2049?

Shared filesystems between Unix/Linux systems (NFS) NFS (Network File System) on port 2049 allows Linux/Unix systems to mount remote filesystems as if they were local disks. It is a core component of shared storage in HPC clusters, NAS appliances, and cloud environments. Older versions (NFSv2, NFSv3) have weak security controls — a misconfigured NFS export can expose entire filesystems to unauthorized access. Use NFSv4 with Kerberos authentication and never expose NFS to the public internet.
