Answer and Explanation:

1. /proc is the virtual filesystem, we use /proc to modify the kernel parameters at running time.

# echo “1” >/proc/sys/net/ipv4/ip_forward

2. /etc/sysctl.conf  when System Reboot on next time, /etc/rc.d/rc.sysinit scripts reads the file /etc/sysctl.conf. To enable the IP forwarding on next reboot also you need to set the parameter.

net.ipv4.ip_forward=1

Here 0 means disable, 1 means enable.

There is one partition /dev/hda14 mounted on /data. The owner of /data is root user and root group. And Permission is full to owner user, read and execute to group member and no permission to others. Now you should give the full permission to user user1 without changing pervious permission.

Answer and Explanation:

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

-rwxr-x--- Full permission to owner user, read and write to owner group and no permission to others.

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/dataext3defaults,acl0 1

• Either Reboot or use: mount –o remount /data
• setfacl –m u:user1:rwx /data
• Verify using: getfacl /data
