Lab 4 - Data communications 1. DHCP information is sent through UDP 2. The Lab example has the same port numbers as my datagram. 3. The Link Layer address is: 00:90:4b:69:dd:34 4. The values in Option 53, DHCP Message Type differentiate the discover message from the request message. 5. The value of the Transaction ID is 0xe6746a7d. The second ID is 0xe4eff25f. A Transaction ID is used so that the DHCP server can differentiate client requests whilst in the the request process. 6. The destination address for the DHCP client and server are both 255.255.255.255. The source IP address for the client is 0.0.0.0, while the server uses its own actual IP address as the source. 7. The IP address of the DHCP server is 192.168.243.1 8. The DHCP server offered the IP address 192.168.243.92 to the client. …show more content…
The “Relay agent IP address” is 0.0.0.0, which means that, there is no DHCP Relay used. There was no Relay Agent used in my experiment. 10. The router line indicates to the client what its default gateway should be. The subnet mask line tells the client which subnet mask it should use. 11. In my experiment, the host requests the offered IP address in the DHCP Request message. 12. The lease time is the amount of time the DHCP server assigns an IP address to a client. During the lease time, the DHCP server will not assign the IP given to the client to another client, unless it is released by the client. Once the lease time has expired, the IP address can be reused by the DHCP server to give to another client. In my experiment, the lease time is 3 days. 13. The client sends a DHCP Release message to cancel its lease on the IP address given to it by the DHCP server. The DHCP server does not send a message back to the client acknowledging the DHCP Release message. If the DHCP Release message from the client is lost, the DHCP server would have to wait until the lease period is over for that IP address until it could reuse it for another
I have to pull two alleles (two straws) from the bag to represent one fish because fishes like humans get two alleles one from their father and one from their mother.
2.1 What are the coordinates for the White House in Degrees, Minutes and Seconds? 38°53'51.47"N 77° 2'11.64"W
To secure the network setup, WPA2 can be used along with the optional Pre-Shared Key (PSK) for authentication. To encrypt the network with WPA2-PSK, the router is configured not with an encryption key but rather plain paraphrase. TKIP(for Temporal Key Integrity Protocol) is used along with the network SSID for generating unique encryption key for the wireless clients.
As the Fig 1 showing, the node which generates the packet is the source node. There are many sensor nodes in a 3-D interest area. The packet is delivered among these sensor nodes and finally try to reach one sink node. Sink nodes are deployed on the water surface. In the figure, it is a multiple-sink topology. Multiple sinks equipped both radio-frequency and acoustic modems are fixed on the water surface.The packet is assumed delivered successfully if it reaches any one of the sink nodes because sink nodes use radio-frequency channel to communicate with each other which is several orders of magnitudes faster than acoustic channel.
Enclosed is a rough high-level conceptual view of the communication channels. This is very preliminary as we don't what suitable devices we can use for multiplexers, demux, and converters. The idea is to design a full-duplex serial com link between point A and B. The bandwidth is limited in the copper wiring (telephone line) probably would not go any higher than 115 kbps using a modem a constraint distance of 5 miles.
IDS is a device or software application that monitors a network for an unauthorised attack.
The two limitations are checking packets one at a time, and checking only some fields of the internet and transport headers. Checking packets one at a time is bad because packets will be examined one at a time, and cannot stop attacks such as DoS. Checking only some fields of the internet and transport headers is bad because will not examine all field of the internet and transport header fields, and cannot stop all attacks such as utilized attack.
The first issue is two nurses failed to show up for work without calling. This issue will take about a week to resolve. The first step is to immediately ensure that their shifts for the day are covered. Then, I would review the attendance policy that is currently in place. I would verify that there is an attendance policy and ensure that it is being enforced. Following the policy review I would document the occurrence in the respective employee files. Lastly, I would set time to meet with the employees individually and go over the policy and the expectations.
date with the latest software and security patches. Reputable antivirus programs such as Norton Security, McAfee Antivirus, and Bitdefender Antivirus and firewall programs should be installed and kept up to date for maximum protection.

Ensure relevant laws and policies provide support for shelters and related services. Promote protocols and guidelines to support standardized implementation of policies Secure adequate state funding for shelters and related services Integrate practices that promote accessibility for all women, such as: ensuring facilities serve women of all ages and can accommodate girls if needed; sheltering women with children; reducing financial barriers, by providing free services and safe transportation; and creating infrastructure and policies which enable women living with disabilities, in humanitarian settings, undocumented or immigrant women, and those with mental health or substance issues to access services. Provide specialized shelters for
The DDS proposed an RFC for 20/10/6/6 with the need to alternate positions. The evidence in file supports this determination. The frequency
This protocol associates a state with each cached copy of shared data block. The different states that can be associated with the block are as follows:
3. The router rejects any application traffic originating from the inside unless it came from the application gateway.
It represents both the longest and shortest time duration paths in the network diagram to finish the project.
