...Lab 4 NAT Joel Garcia Cgs 4285 Contents Objective: 3 Procedures: 3 Experience: 3 Conclusion: 4 Data Table Error! Bookmark not defined. Questions 5 Objective: The objective of this lab is to configure DNS client settings, for Linux and Windows Stations, to observe DNS in action, and to observe NAT in action. Procedures: 1. First, verify that workstation 1 and workstation 2 have the correct IP addresses and default route. 2. Configure DNS servers for workstation 1 and workstation 2. After, configure workstation 2 to use 131.94.131.43 as a DNS resolver by entering the command: echo “nameserver 131.94.133.43” > /etc/resolv.conf. Afterwards, configure workstation 1by going to TCP/IP Properties and adding 131.94.133.43 as the DNS server. 3. Next, find the public IP address of the eth0 interface on the monitor workstation by using the ifconfig command. As a root on the monitor, input: tcpdump -i eth0 -n -s 0 -w /tmp/public.pcap host PUBLICIPADDRESS & tcpdump -i eth1 -n -s 0 -w /tmp/private-net1.pcap & tcpdump -i eth2 -n -s 0 -w /tmp/private-net2.pcap & 4. Then, connect to port 7 and source port 2000 on workstation 1 with the command: nc -p 2000 cgs4285.cs.fiu.edu 7 Type in three or four lines of random data and repeat the same process for workstation 2. Enter “ctrl+c” afterwards to stop the process on workstation 1 and 2. 5. On the monitor station...

...Labs 4B Lab 8.4 1.What extra parameters are necessary in the network command when using OSPF, as compared with RIP, RIPv2, and EIGRP? Router(config)#router ospf process-number 2. What is the purpose of areas in OSPF? An area defines the confines within which LSAs are contained. 3. What is the purpose of the DR? On broadcast, multiaccess networks, OSPF elects a DR, which acts as a central point for LSAs. On multiaccess networks such as Ethernet, OSPF routers elect a DR and establish adjacencies with the DR only. 4. What determines which router will be the DR? If the priorities are not changed and all the priorities are equal, the router with the highest router ID will become the DR and the router with the second-highest will become the BDR. 5. What are the two steps involved when configuring OSPF authentication? Configuration of authentication keys on each OSPF interface. Configuration of area authentication. Lab 9.1 1.Does static NAT conserve IP addresses? Why or why not? Static NAT is a mapping of one inside IP address to one outside IP address. It does not conserve IP address space. 2. Does PAT conserve IP addresses? Why or why not? PAT allows multiple internal, private IP addresses to use a single external registered address. 3. Why do dynamic NAT and PAT require configuration of an access list? The standard access control list is used to define what internal traffic will be translated. 4. What is the purpose of the address pool in...

...Phase 1: Identifying Requirements, Putting the Network Together Scenario NuggetLabs Industries is growing significantly. Due to space limitations, five employees currently share single cubicles…at the same time. While this is great for team building, these space limitations are now impacting business productivity. NuggetLabs has now leased an additional office building roughly 20Km from their headquarters location. While this office will eventually connect to the HQ office, it will initially be set up independently. NuggetLabs Industries has heard rumors of your ninja-like network consultation skills and has agreed to pay you an excessive amount of money to design and build their network infrastructure. Gathering Information To help guide this initial configuration, you‘ve assembled a list of requirements based on various meetings with management. * The new office will initially house 75 employees, each with their own Cisco IP Phone and PC. This office may eventually scale to 200 employees over 5 years. * The Windows admins are planning to install a new pair of redundant servers at the new office. They plan to manage all the IP addresses for DHCP on these servers and are waiting for you to tell them what IP address range they should use. * Windows admins: Jeff Service - (602) 555-1293, Mike Pack (480) 555-9382. * The new office is a two story building with the Main Distribution Frame (MDF) in the northwest corner of the first floor.

...Design a Layered Security Strategy for an IP Network Infrastructure NaTasha Scott Dr. Danielle Babb CIS 534 Advanced Network Security Design March 6, 2014 1. Block diagram design of a layered security solution 2. A written function overview of your design Lab Assessment Questions and Answers for Lab 8 1. Explain why a layered security strategy helps mitigate risk and threats both external and internal. Multiple layers can be used to secure internal threats like keeping employees from accessing inappropriate material, update and patch workstations and run current anti-virus/malware on workstations daily. The layers also help mitigate external threats like hackers by using firewalls and shutting traffic out of the internal network. 2. Why is it a good idea to put shared servers and services on a DMZ when both internal and external users need access? When you have a DMZ there are two firewalls to protect the internal network from external threats. The necessary servers can be placed between the two in order to allow access from either side through strict firewalls while still allowing very little external traffic into the internal zone. The outermost firewall can allow a certain set of traffic to come in and access the servers. The inner most firewall blocks access into the intranet while allowing internal users to access the information on the servers. 3. What recommendations do you have for the future e-commerce server and deployment in regard to physical...

...(School Physical Plant and Facilities Management) GRPE311 A COMPARATIVE ANALYSIS ON SCHOOL PHYSICAL PLANT AND FACILITIES (Manila Cathedral School and San Rafael Parochial School) Introduction The school site must be suitable and adequate for its activities. School buildings are designed and constructed in conformity with the provisions of the Building Code. Facilities are appropriate and adequate to implement the philosophy, vision, mission, goals and objectives, and activities of the school. The physical environment, facilities and equipment support teaching and learning in all curricular offerings, delivery of services as well as optimal student development and achievement. School facilities are safe, clean, and well maintained for all faculty and students engaged in them. The school site and facilities are regularly inspected for effective operation and meet all applicable laws including health and safety code requirements. (DepEd ESC Re-certification Assessment Instrument PEAC-FAPE Secretariat 2010) In the first part of this analysis, the focus will be in more general terms of the school’s physical environment (plant and facilities) as shown in the succeeding tables, the format and the survey instrument will be a modification of the ESC School (Re-) Certification process tool basically designed to assess the extent of compliance with the DepEd Minimum Quality Standards as well as to evaluate the school’s characteristics, its qualitative...

...n IP (Internet Protocol) address is a unique identifier for a node or host connection on an IP network. An IP address is a 32 bit binary number usually represented as 4 decimal values, each representing 8 bits, in the range 0 to 255 (known as octets) separated by decimal points. This is known as "dotted decimal" notation. Example: 140.179.220.200 It is sometimes useful to view the values in their binary form. 140 .179 .220 .200 10001100.10110011.11011100.11001000 Every IP address consists of two parts, one identifying the network and one identifying the node. The Class of the address and the subnet mask determine which part belongs to the network address and which part belongs to the node address. Address Classes There are 5 different address classes. You can determine which class any IP address is in by examining the first 4 bits of the IP address. Class A addresses begin with 0xxx, or 1 to 126 decimal. Class B addresses begin with 10xx, or 128 to 191 decimal. Class C addresses begin with 110x, or 192 to 223 decimal. Class D addresses begin with 1110, or 224 to 239 decimal. Class E addresses begin with 1111, or 240 to 254 decimal. Addresses beginning with 01111111, or 127 decimal, are reserved for loopback and for internal testing on a local machine; [You can test this: you should always be able to ping 127.0.0.1, which points to yourself] Class D addresses are reserved for multicasting; Class E addresses are reserved for future use. They should...
