Configure a firewall on a Linux machineSet up a stateless firewall that accomplishes the following objectives. Allows web traffic to external servers with class A IP addresses and at ports 80 and 443.Allows secure shell connections from your machine to any machine at port 22.Allows secure shell connections from any one of the fox servers to your machine at port 22.Allows any critical traffic needed for your machine to function. For VDI machines the firewall should allow all TCP traffic to and from 10.100.1.161 through 10.100.1.164 (which are the VDI gateways) and all traffic on the loopback interface. Blocks all other TCP traffic. Logs all blocked packets before dropping them. Use a custom label to easily extract the log information generated by the firewall rules you created.

Now you’re on your own. include a short summary of this section with plots in your lab report. write a matlab script file to do steps (a) through (d) below. include a listing of the script file with your report. 1 the soundsc(xx,fs) function requires two arguments: the first one (xx) contains the vector of data to be played, the second argument (fs) is the sampling rate for playing the samples. in addition, soundsc(xx,fs) does automatic scaling and then calls sound(xx,fs) to actually play the signal. mcclellan, schafer, and yoder, dsp first, 2e, isbn 0-13-065562-7. prentice hall, upper saddle river, nj 07458. c 2015 pearson education, inc. 4 mcclellan, schafer and yoder, signal processing first. prentice hall, upper saddle river, new jersey, 2003. c 2003 prentice hall. (a) generate a time vector (tt) to cover a range of t that will exhibit approximately two cycles of the 4000 hz sinusoids defined in the next part, part (b). use a definition for tt similar to part 2.2(d). if we use t to denote the period of the sinusoids, define the starting time of the vector tt to be equal to t , and the ending time as ct . then the two cycles will include t d 0. finally, make sure that you have at least 25 samples per period of the sinusoidal wave. in other words, when you use the colon operator to define the time vector, make the increment small enough to generate 25 samples per period. (b) generate two 4000 hz sinusoids with arbitrary amplitude and time-shift. x1.t / d a1 cos.2
