Because no_root_squash is enabled, your client root account acts as the server root account. You can now change the ownership or permissions of the locked files:
Move beyond simple IP authentication and use NFSv4 with Kerberos for robust authentication and encryption.
Systematically tries all combinations. Use this if the password was complex, but it may take significantly longer.
Using recovery tools requires strict adherence to security protocols to prevent data leaks. nfs password recovery version 2.0

Losing administrative access to your Network File System (NFS) storage environment can paralyze your entire enterprise network. NFS Password Recovery Version 2.0 is a specialized utility designed to recover lost or forgotten authentication credentials, mount keys, and security tokens across distributed networks.
Losing access to secured Network File System (NFS) shares can stall enterprise workflows and disrupt critical data pipelines. represents a specialized category of administrative tools and methodologies designed to recover lost security credentials, manage Kerberos keytabs, and restore access to protected network shares. Because no_root_squash is enabled, your client root account
Because these are life safety devices, "Version 2.0" of the recovery protocol involves strict verification to prevent unauthorized access. You cannot simply call tech support for a code. Documentation : You must provide the generated cryptic code on a formal Password Request Form Verification
Decrypts credentials across NFSv3, NFSv4, and hybrid SMB-NFS environments.
Once you have regained access using NFS Password Recovery Version 2.0, you need to lock it down. The biggest reason for lockouts is not hacking—it’s forgotten passwords across multiple launchers (Steam, Epic, EA App). Use this if the password was complex, but
# On KDC master kadmin.local ktadd -k /tmp/nfs.keytab nfs/server.example.com scp /tmp/nfs.keytab server:/etc/krb5.keytab
This triggers a "Version 2.0" soft reset. It resets the administrator password to default (often left blank, or set to "admin") and reverts network settings to DHCP without deleting your actual data or NFS share configurations. 2. Recovering via SSH and Root Access
