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.

The decimal numbers must be within the numeric range of 0-255, each IPv4 addresses consist of 4 parts. 3. Each part should conform to the 1-byte requirement. 4. Depending on the value of the first byte of the address, IP addresses can be divided into classes. 5. Network classes are of 3 type and have some specific range • Class A 0-127 • Class B 128-191 • Class C 192-233 6. Class division enables us efficient use of the address numbers. 7. Assigned network numbers are maintained in a database managed by InterNIC to insure that each assignment is unique. 8. After obtaining a network number, the host numbers may be assigned as required, for data transfer ARP maps the IP address to the MAC address of the device. 9. Routers are used for transferring data between 2 devices, routers are default gateway ...
