...The Modified Parallelized File Transfer Protocol for Multi-users Wei-Chen Lin Jiun-Jian Liaw Chiung-Ta Wu Department of Information and Communication Engineering Chaoyang University of Technology Taiwan(R.O.C.), Taichung s9930615@cyut.edu.tw, jjliaw@cyut.edu.tw Abstract—File Transfer Protocol is the most popular file transfer standard. This FTP can let a computer system connect to the internet via a communication network, and it can also access the system resources from the internet. File server is being downloaded now by TCP/IP protocol, while before it was downloaded by signal server. Due to the limited flow control, the old method could not use download time efficiently. In order to solve the flow control problem, some researchers came up with a distributed file transfer method that can share the document with other users, thus allowing the shortest transfer time using neighboring servers. Although the distributed file transfer can reduce the file transfer time, it was not concerned with the quality of the transfer between two servers, and was inappropriate for file segmentation and transfer, so the file transfer could not attain the optimal transfer efficacy. Based on our research, we propose a new method called Distributed Parallelized File Transfer Protocol (DPFTP). This method is based on Parallelized File Transfer Protocol (P-FTP) and is beneficial to multi-users, as it utilizes server loading and reduces the download time. Keywords—FTP; P-FTP; DPFTP ; multi-users; ...

...BRIAN LAPITAN SUBMITTED BY: JOHN ALLEN C. RONQUILLO BSICT-IB 1. What is Internet? - The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (often called TCP/IP, although not all applications use TCP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructureto support email. 2. History of Internet? - The history of the Internet began with the development of electronic computers in the 1950s. This began with point-to-point communication between mainframe computers and terminals, expanded to point-to-point connections between computers and then early research into packet switching. Packet switched networks such as ARPANET, Mark I at NPL in the UK, CYCLADES, Merit, Tymnet, and Telenet, were developed in the late 1960s and early 1970s using a variety of protocols. The ARPANET in particular led to the development of protocols for internetworking, where multiple separate networks could be joined together into a network of network 3. Internet vs. internet? - one existing distinction between "Internet" and "internet" has been...

...Lab #5 1. What is the purpose of the address resolution protocol (ARP)? ARP is a protocol used for resolution of IP addresses into MAC addresses and vice versa. 2. What is the purpose of the dynamic host control protocol (DHCP)? DHCP is used on an IP network to assign IP addresses to computers on the network. This is done without any human intervention. The computer requesting a DHCP-assigned address is given one by the network’s DHCP server within a range of assigned IP addresses which are tracked by the DHCP server. A DHCP-assigned address is normally assigned to a computer for a set lease time and after that lease expires, the computer must renew the IP address or request a new one. 3. What was the DHCP allocated source IP host address for the Student VM and the Target VM? (retracted) 4. When you pinged the targeted IP host, what was the source IP address and destination IP address of the ICMP echo-request packet? Source: 10.134.112.42 (my external IP) Destination: 98.138.253.109 (www.yahoo.com) 5. Did the targeted IP host respond to the ICMP echo-request packet with an ICMP echo-reply packet? If yes, how many ICMP echo-reply packets were sent back to the IP source? Yes, the target did respond with ICMP echo reply packets. My computer sent four request packets and the destination server sent four reply packets back. 6. Find a TCP 3-way handshake for a TELNET, FTP, or SSH session.

...transmission control protocol and the user Datagram protocol, a port number is a 16 bit integer that is put the header appended to a message unit. This port number is passed logically between the client and the server transport layers and physically between the transport layer and the Internet Protocol layer and it will forward it on to the other layers. For an example, a request from a client to a server on the internet may request a file to transfer from the host File Transport Protocol (FTP) server. In order to pass that request which is passed by us to the FTP in the remote server, the Transmission Control Protocol (TCP) identifies the port number which is of 16 bit length, then that port will forward the request to the FTP Server. FTP and the FTP Port Number The File Transfer Protocol (FTP) is a standard network protocol used to transfer computer files from one host to the other host over a TCP – based network, for an example Internet. FTP is a Client – server architecture and uses a separate control and the data connections between the client and the server. The model of the FTP is shown below. Fig 1: File Transport Protocol Model Executing an FTP port connection through a client is two – stage process requiring the use of two different ports. Once the user enter the name of the server and the login details in the authorization fields of the Client FTP, the FTP connection will be established and the FTP control port will get opened, by default the FTP uses the Port number...

... For the purpose of this investigation, we are primarily concerned with the FTP (File Transfer Protocol) sessions and the file names they contained. We can use this information to identify the persons responsible for the data leak at Corporation Tech’s network. First, we created a new collection in NetWitness. We titled the collection Final Project for the purposes of this investigation. We then imported packets from the captured packets file titled ftpcapture.pcap. Once NetWitness imported the files, we were able to view information such as the login information and files transferred. Below is the information we collected. Source IP | Destination IP | Protocol | Username | Password | Files | 172.16.177.132 | 172.16.177.157 | FTP (21) | badguy | you will never guess this !! | badnotes1.txt | 172.16.177.132 | 172.16.177.157 | FTP (21) | badguy | you will never guess this !! | badnotes2.txt | These files were transmitted on July 31, 2010 at 1:08:58 AM and totaled to 5.71KB, which is shown below in the following screen captures. After our investigation of the FTP files in question, we investigated the remaining packet capture but did not identify anything further that could be considered questionable. The primary communication was between the IP addresses 172.16.177.132 and 172.16.177.157. Another attempt to login was made from the same IP addresses at the same time as the file transfer was performed using the credentials...

After viewing these and finding out exactly what each does it has been decided that I will remove three of them. The reason for this is that they can automatically download malware or viruses to your computer. I will remove the file transfer protocol by going through the FTP accounts. This protocol will be picked so that certain information cannot be transferred over the internet. The next one that I will remove is the Peer-to-peer (P2P) file-sharing service.

...importance of communication protocols and define the protocols that would be most effective for the Kudler Fine Foods network. Understanding the usefulness of a traffic analysis and the effect of latency response time and jitter are also necessary. Other aspects of developing an effective network design are understanding the effect of data rate on each part of the network and developing strategies to ensure the availability of network access in switched and routed networks. Communication protocols are the pre-defined set of rules which enable the networked devices to communicate effectively with each other. These protocols determine how messages are sent and received, detect and recover transmission errors and determine how messages are formatted. These protocols are important because they define the guidelines which determine how computers communicate with each other in a standardized manner. The protocol identified for Kudler Fine Foods is the Transmission Control Protocol/Internet Protocol (TCP/IP) Protocol Suite. There are many advantages to using this protocol. It is compatible with all operating systems, hardware, software and network configurations. This protocol is routable and highly scalable which enables expansion of the network as needed. It also provides very reliable data delivery. The Suite includes protocols such as Hypertext Transfer Protocol (HTTP), File Transfer Protocol (FTP) and Simple Mail Transfer Protocol (SMTP).

...The protocol was first specified June 1980 and updated in RFC 959,[2] which is summarized here.[5] The server responds over the control connection with three-digit status codes in ASCII with an optional text message. For example "200" (or "200 OK") means that the last command was successful. The numbers represent the code for the response and the optional text represents a human-readable explanation or request (e.g. ).[1] An ongoing transfer of file data over the data connection can be aborted using an interrupt message sent over the control connection. Illustration of starting a passive connection using port 21 FTP may run in active or passive mode, which determines how the data connection is established.[6] In active mode, the client creates a TCP control connection to the server and sends the server the client's IP address and an arbitrary client port number, and then waits until the server initiates the data connection over TCP to that client IP address and client port number.[7] In situations where the client is behind a firewall and unable to accept incoming TCP connections, passive mode may be used. In this mode, the client uses the control connection to send a PASV command to the server and then receives a server IP address and server port number from the server,[7][6] which the client then uses to open a data connection from an arbitrary client port to the server IP address and server port number received.[5] Both modes were updated in September 1998 to support...

You will generate that traffic by exploiting a cross-site scripting (XSS) vulnerability in the Damn Vulnerable Web Application (DVWA) tool. In the lab environment, you will be capturing traffic on one interface. In a real-world situation, it is likely the machine would be straddling both an internal network and an external network. In that case, you would want to want to monitor both sides of the interface.

...Richman Investments holds requirements for the usage of the company network including filtering policies for network traffic through an AUP. Acceptable use policy (AUP) would start with the User Domain. The user domain is the employee within an organization who is granted access to the information system for the organization. There are roles and tasks, responsibility, and accountability that go into an acceptable use policy for the user domain. Within the user domain, access to the LAN to WAN, web surfing, and internet could be used help gather information between customers and employees. LAN to WAN is the activities between LAN to Wan and firewalls, routers, intrusion, detection, and workstations. Web surfing determines what a user can obtain on company time with company resources. Internet, is when the user has access to the internet with the types of controls the organization has on the certain internet sites being accessed. Although LAN to WAN, web surfing, and internet have some of the same characteristics, they also have different specific IT infrastructures it affects. . For the LAN to Wan AUP, it will goes with the roles and task parts of the user domain. Users would be given access to certain systems, applications, and data depending on their access rights.
