Assignment 7 Week 7
Linux Networking – NT1430 - Week #7 Questions
1. What is the difference between the passwd and yppasswd utilities? Yp has something to do with NIS
2. How would you make NIS user information override local user information on client systems? Nsswitch.com?
3. Why does the /etc/passwd file need two NIS maps? Ties into uid number and password
4. How can you find out if the working directory is the home directory of an NIS user? Yp cat pastwd
5. What advantage does NIS provide when you use it with NFS?
NFS client to server; NIS automatic
6. List some reasons to use NFS.
Reduce storage needs, simplify systems administration, backups are simpler
7. What does the /etc/fstab file do? Contains critical system files to boot up system
8. When is it a good idea to disable attribute caching? Writing to directory multiple times (web server and database servers)
9. Which two daemons are parts of the Samba suite? SMBD and NMBD
10. What steps are required for mapping a Windows user to a Linux user? Update etc/samba/users?
11. Describe how Samba’s handling of users differs from that of NFS.
NFS hierarchy is mounted by /root
12. How would you prevent NIS from exporting the root user and other system users to clients?
Adjust the users UID outside of the super user number range
13. Some diskless workstations use NFS as swap space. Why is this useful? The swap space only has space for memory
14. WINS resolution allows hosts to define their own names. Suggest a way to use Samba to assign names from a centralized list. 2-enable dns 3-centralize 4-configre all clients to use WINS
