63.List all the Network file system (NFS) scripts.
Ans.
1. sync – It forces NFS server to perform disk write operation before informing client that request is complete.
2. async – It makes NFS server to cache disk write operation.
3. hide – It hides subdirectory of an exported file system.
4. nohide – It unhide subdirectory of an exported file system.
5. ro – It gives read only access to clients who has mounted the exports.
6. rw – It fives read/write access to clients who has mounted the exports.
7. root_squash – It prevents root user on an NFS client from having root privileges on NFS server.
8. no_root_squash – It disables root_squash.
9. secure – It accepts only if generating from port numbers less than 1024.
10. insecure – It accepts client’s request even if generating from port numbers higher than 1024.
11. secure_blocks – It requires clients to be authenticated who request for lock operation.
12. insecure_locks – It doesn’t require clients to be authenticated who request for lock operations.
13. subtree_check – It ensures only a part of filesystem is exported and file requests apply to files in the exported portion of the file system.
14. no_subtree_check – It disables subtree_check.
Two additional configuration files if you’re using NFSv4
15. /etc/gssapi_mech.conf – It implemets NFSv4 features. It controls gss daemon one need the information to configure secure RPC. It needs no modification.
16. /etc/idmapd.conf – It is idmapd daemon. It translates NFSv4 IDs to user and group.
