Write a client and a server that permit the client to execute arbitrary shell commands on the server host. (If you don't implement any security mechanism in this application, you should ensure that the server is operating under a user account where it can do no damage if invoked by malicious users.) The client should be executed with two command-line argumentAfter connecting to the server, the client sends the given command to the server, and then closes its writing half of the socket using shutdown(), so that the server sees end-of-file. The server should handle each incoming connection in a separate child process (i.e., a concurrent design). For each incoming connection, the server should read the command from the socket (until end-of-file), and then exec a shell to perform the command. Here are a couple hints:
See the implementation of system() in Section 27.7 for an example of how to execute a shell command. By using dup2() to duplicate the socket on standard output and standard error, the execed command will automatically write to the socket.
In Fedora Core 4, if you need to create a mount point on the current file system, you first create a directory in the file system using the ____ command
Suppose we enhance a machine making all floating-point instructions run five times faster. If the execution time of some benchmark before the floating-point enhancement is 10 seconds, what will the speedup be if half of the 10 seconds is spent exe..
Draw a PDA for the language L over {0,1} consisting of strings with an equal number of 0's and 1's. So 010011 would be in this language. Next draw a DFA recognizing 0?1?. Use the algorithm from class to draw a PDA for the intersection of these two..
Suppose you have a deque D containing the numbers (1,2,3,4,5,6,7,8), in this order. Suppose further that you have an initially empty queue Q. Give a pseudo-code description of a function that uses only D and Q (and no other variables or objects) and ..
Write a function to simulate the game show problem. Your function should randomly select locations for the prizes, select a door at random chosen by the contestant, and then determine whether the contestant would win or lose by sticking with the o..
Using one or more of the databases for Computer Networks and Cyber Security, search for peer-reviewed journal articles about the communication theory or by the name of the person you selected to see if communication research on that theory has be..
If X is a non-negative random variable with E(X) = ?, then Markov's inequality tells us that for every a, P(X ? a) ? ?/a. As we saw in class, this bound is sometimes very loose. In this problem we'll look at a situation in which extra information ..
Use the "time" option on linux to capture the experimental run-time of the various versions of your algorithms, on various sizes of inputs. The sizes to report are 50 elements, 50 commands; 50 elements 1000 commands; 1000 elements 1000 commands; a..

Create a graphic rendering of the critical path for your project using Visio or its open source alternative software. Note: The graphically depicted solution is not included in the required page length.
What data structures are supported by the library? What types of data are recommended for use with each data structures object? Which classes contain which data structures, and what methods does the library provide?
