According to the question that only the owner user (root) and group member (sysuser) can fully access the directory so: chmod 770 /archiveNO.58 CORRECT TEXTCopy /etc/fstab to /var/tmp name admin, the user1 could read, write and modify it, while user2 without any permission. # cp /etc/fstab /var/tmp/# chgrp admin /var/tmp/fstab# setfacl -m u:user1:rwx /var/tmp/fstab# setfacl -m u:user2:— /var/tmp/fstab# ls -l-rw-rw-r–+ 1 root admin 685 Nov 10 15:29 /var/tmp/fstabNO.59 Create a user alex with a userid of 3400. The password for this user should be redhat. useradd -u 3400 alexpasswd alexsu -alexNO.60 Your System is going use as a router for 172.24.0.0/16 and 172.25.0.0/16. Enable the IP Forwarding.1. echo “1” >/proc/sys/net/ipv4/ip_forward2. vi /etc/sysctl.conf net.ipv4.ip_forward=1 see explanation below.Explanation/proc is the virtual filesystem, containing the information about the running kernel.To change the parameter of running kernel you should modify on /proc. From Next reboot the system, kernel will take the value from /etc/sysctl.conf.NO.61 Download the document from ftp://instructor.example.com/pub/testfile, find all lines containing [abcde] and redirect to /MNT/answer document, then rearrange the order according the original content.

The Initial Size of that Logical Volume is 400MB. Make successfully that the size of Logical Volume 200MB without losing any dat a. The size of logical volume 200MB to 210MB will be acceptable. First check the size of Logical Volume: lvdisplay /dev/vo/myvolMake sure that the filesystem is in a consistent state before reducing:# fsck -f /dev/vo/myvolNow reduce the filesystem by 200MB.# resize2fs /dev/vo/myvol 200MIt is now possible to reduce the logical volume. #lvreduce /dev/vo/myvol -L 200M Verify the Size of Logical Volume: lvdisplay /dev/vo/myvol Verify that the size comes in online or not: df -hNO.65 SIMULATIONPlease open the ip_forward, and take effect permanently. See explanation below.Explanation/Reference:Explanation:vim /etc/sysctl.conf net.ipv4.ip_forward = 1sysctl -w (takes effect immediately)If no “sysctl.conf” option, use these commands:sysctl -a |grep net.ipv4sysctl -P net.ipv4.ip_forward = 1sysctl -wNO.66 Find the rows that contain abcde from file /etc/testfile, and write it to the file/tmp/testfile, and the sequence is requested as the same as /etc/testfile.

One Network is 192.168.0.0/24 and Another Network is 192.168.1.0/24. Both network’s IP address has assigned. How will you forward the packets from one network to another network? echo “1” >/proc/sys/net/ipv4/ip_forwardvi /etc/sysctl.confnet.ipv4.ip_forward = 1If you want to use the Linux System as a Router to make communication between different networks, you need enable the IP forwarding. To enable on running session just set value 1 to/proc/sys/net/ipv4/ip_forward. As well as automatically turn on the IP forwarding features on next boot set on /etc/sysctl.conf file.NO.69 SIMULATIONSELinux must be running in the Enforcing mode.

It will ask for the Starting Cylinder: Use the Default by pressing Enter Key.5. Type the Size: +100M you can specify either Last cylinder of size here.6. Press P to verify the partitions lists and remember the partitions name.7. Press w to write on partitions table.8. Either Reboot or use partprobe command.9. Use mkfs -t ext3 /dev/hda?ORmke2fs -j /dev/hda? To create ext3 filesystem.vi /etc/fstabWrite:/dev/hda? /data ext3 defaults 1 2Verify by mounting on current Sessions also: mount /dev/hda? /dataNO.71 Copy /etc/fstab to /var/tmp name admin, the user1 could read, write and modify it, while user2 without any permission.
