According to QUESTION: We should give the full permission to user user1 without changing the previous permission. ACL (Access Control List), in ext3 file system we can give permission to certain user and certain group without changing previous permission. But that partition should mount using acl option. Follow the steps
vi /etc/fstab /dev/hda14 /data ext3 defaults,acl 0 1
Either Reboot or use: mount -o remount /data
setfacl -m u:user1:rwx /data
Verify using: getfacl /data

B. We know that every files/directories are owned by certain user and group. And Permissions are defines to owner user, owner group and other.

A. #vi /etc/resolv.conf nameserver 168.28.293.250 # dig server1.example.com #host server1.example.com DNS is the Domain Name System, which maintains a database that can help your computer translate domain names such as www.redhat.com to IP addresses such as
216.148.218.197. In Redhat Enterprise Linux, you need to specify the DNS server into /etc/resolv.conf file. After Specifying the DNS server address, you can verify using host, dig and nslookup commands.
