Create a firewall on the virtual machine. Use the output from the command iptables -L -v to show that the virtual machine has been properly firewalled.
To configure the firewall add this line to /etc/sysconfig/system-config-firewall
--port=5438:udp or --port=8080:tcp
(tcp - reliable protocol delivery or udp - not secured but ultra fast packet delivery )
To display firewall
iptables -L -n | grep 'udp.*5438'
or iptables -L -v

It's good practice and if I have to test one or more of your rules, I can replace the address in the variable. For any packets you REJECT or DENY, those should be logged. That means you'll need to modify the rule so that if the rule matches...

In C++ l. Assume that a system has a 32-bit virtual address with a 4-KB page size. Write a program that is passed a virtual address (in decimal) on the command line and have it output the page number and offset for the given address. As an example, your program would run as follows: yourprogram 19986 Your program would output: The address 19986 contains: Page number = 4 Offset = 3602 Writing this program will require using the appropriate data...
