ABC Threads: Network Issues
The headquarters of ABC threads, which is a large Textile Company located in Dallas, Texas has its network administrator, based in Houston. Mac is the network administrator and was conducting a routine maintenance on the network. While conducting the maintenance Mac came across a ticket opened by an employee. On further investigation Mac figured out that the complaint was that the employee was facing trouble in connecting to the network.
As the network administrator, Mac then began a trace in order to capture the communications from the employee (client IP host) that cannot connect to the rest of the company network or on the other side of the local router.
Additionally, the employee is able to communicate with all the other local systems without any issues except for the client IP host which is not able to connect.
On the basis of your understanding of the scenario, addresses the following:
1. What are possible issues based on the information provided?
2. What kind of information would a network administrator look for in the trace file that was captured from the IP Host to the local router?
3. What are expected modifications to be made in order for the IP Host to communicator through the router?
4. What security considerations should be made or implemented in order to secure the communication of the network?
Explanation / Answer
Generally the major connectivity issues involve problems with routing table entries. Every packet in netork being processed by a TCP/IP host has a source and destination IP address.while receiving each packet, the IP protocol examines the destination address of the packetand after that it compares it with entries in its local routing table, and then decides what to do.
He traces the logs by using traceroute command ich route an IP packet follows to a remote system. Traceroute command to uncover any routing misconfiguration and routing path failures.
Suppose if the destination IP address is itself, then the packet is passed up to a protocol layer above IP.
If the packet is destined for another known network,then the packet is forwarded through locally-attached network adapters.
Oterise the packet is discarded.
