Lab Questions You should log in to one (or both) of your Linux machines to answer these questions. 1. Network attacks are often made through open ports on the system, thus it is important to know what ports are in use. Although a daemon can run on any port (assuming permissions allow it), there are some well-known ports. For each network daemon given, give the well-known port numbers and protocol(s) used. Example: http 80/tcp/udp hypertext transfer protocol Answer for the following: irc - 194/tcp/udp - Internet Relay Chat domain - 53/tcp/udp - Domain Name System ftp - 21/tcp/udp - File Transfer Protocol smtp - 25/tcp - Simple Mail Transfer Protocol netbios-dgm - 138/udp - NetBIOS Datagram Service finger - 79/tcp - Finger Protocol ssh - 22/tcp - Secure Shell telnet - 23/tcp - Telnet Protocol 2. "netstat -an" will give you a list of open ports, but not the name of the executable file listening at that port. "lsof" (List Open Files) allows you to link the open port/socket to the file that opened it (among a thousand other things). "/usr/sbin/lsof" is installed by default on most Linux systems, but not necessarily on other free Unixes (such as BSD). Use "lsof" to list all open network TCP sockets. Which command arguments did you use? Paste in the listing "lsof" gave you. 3. A daemon such as knockd will not show up in a netstat listing. What is the concern of this? 4. Name the command (daemon) associated with each of the TCP sockets from question 2. Title_with_topic: Network Ports, Daemon Identification, and Concerns

Problem Two In a 2-bus system, a load that consumes 100 MW of real power and 50 MVAR of reactive power is connected to a generator through a line with an impedance $z = 0.02 + j0.06$ p.u. Assuming bus 1 is the generator (slack) bus and bus 2 is the load bus: a) Draw a single-line diagram for the system. b) If the generator voltage is 1.0 p.u. at angle 0°, find $V_2^{(2)}$, in per unit, using Gauss Seidel method. Use $S_{base} = 100$ MVA.
