Jenna works for your company's Human Resources department. For several years she has volunteered to instruct new and present employees on the use of office applications in a special training lab environment. Due to the sensitive nature of this environment, security policies are more strict for the lab than the rest of the network. A more refined policy was just set in place by your administrator last Friday. On Monday, Jenna calls you and explains that she can no longer log into the lab machines locally. After further troubleshooting, you discover that any user that is a member of the "Lab Instructors" group can no longer log into any of the lab machines. What is most likely the problem?

When designers make compromises during the engineering design process the result is often what?

Usually, when we sniff packets, we are only interested certain types of packets. we can do that by setting filters in sniffing. scapy’s filter use the bpf (berkeley packet filter) syntax; you can find the bpf manual from the internet. set the following filters and demonstrate your sniffer program again (each filter should be set separately): (a) capture only the icmp packet. (b) capture any tcp packet that comes from a particular ip and with a destination port number 23. (c) capture packets comes from or to go to a particular subnet. you can pick any subnet, such as 128.230.0.0/16; you should not pick the subnet that your vm is attached to.

[a] create a class called “cycle” which has two instance integer variables as properties, “numberofwheels” and “weight.” create a constructor with two parameters, using the same variable names in the parameter list. assign each variable to numberofwheels” and “weight” respectively. write a separate application to test the class and display its properties. note: do not change the names of the instance variables or the variables listed in the constructor’s parameter list. [b] edit your class cycle by adding a default constructor which will assign the default values of 100 to represent the numberofwheels, and 1000 to represent the weight, by invoking a call to the other constructor. modify your application created in [a] to test the class.
