How to configure Network file system version 4 (NFSv4) client?

69.How to configure Network file system version 4 (NFSv4) client?
Ans.
1. There are two new options listed in NFSv4 are introduced as: clientaddr and ports

2. The version 3 of NFS introduced NFS over TCP, which improved NFS’s reliability.

3. In NFSv3, users use the mount option i.e., tcp as client whether client wants to use TCP or UDP to communicate with the server.
NFSv4 replaces tcp or udp with a single option i.e. ports=tcp or udp

4. The default buffer size for NFSv4 is 8192 bytes, but it can grow to as large and by 32,678 bytes, which results performance improvements.

5. Following are the mount options:
clientaddr=n – Declares client to be multihomed
proto=type – Declares port as either udp or tcp
resize=n – declares read size of clients buffer
wsize=n – Declares write size of clients buffer
sec=mod – Declares security model as either krb, krb5 etc.

What are the server and client security considerations?

72.What are the server and client security considerations? Ans. Server security considerations: 1. Always use the root_squash option in /etc/exports. 2. Enabled by default so do not disable it. 3. With root squashing clients root account can’t even access or change files that only server’s root account can change or access. Client security considerations: 1. Disable SUID (set UID) programs on NFS mounts using nosuid option. 2. Prevents server’s root account from creating an SUID root program on an exported FS, logging in to the clients as a normal user, and then using the UID root program to become root on the client.
