Introduction:
* -------------------------------------------------
One of the benefits of the internet is transferring file between computers to share information between people, but computers which run different operating systems need a common language between them to understand each other and this language is called protocols (Washburn et al., 1996). FTP (File Transfer Protocol) is a protocol to transfer files that described for the first time in the early seventies and standardized in 1982 (Matthews, 2005). SFTP (SSH File Transfer Protocol) is another file transfer protocol, but the first RFC describing SFTP was released in 2001 (Ylonen et al. 2001). Organizations have to provide file transfer services to their customers, and they should choose the secure file transfer protocol which will secure their costumers files. In this essay, a comparison between FTP and SFTP would be making from three aspects. Firstly, I will illustrate the differences between FTP and SFTP in starting communication methods, and how they maintain the connection and the ports used by them. Secondly, I will focus on security vulnerabilities of FTP and SFTP and their effects on users and files security. Finally, I will compare the speed of files transferring in FTP and SFTP for different files with different sizes. * -------------------------------------------------
Communication Approach: * -------------------------------------------------
System architecture identifies the system hardware and software requirements, and it has effects on system performance and throughput. FTP and SFTP are reliable data transfer services, which means they need to maintain the connection between the server and the client and guarantee transferred file integrity, because of this they were built on TCP (Transmission Control Protocol) (Postel et…...

...database entries from server to client? Hashing the input entries of a database is not considered encryption because the data in the database is still in a readable. Hash appends to the data as the fingerprint ensuring data integrity is still there. 9. Where would you remove a user’s certificate from being able to access systems on you network? From the Certificate authority server in LDAP as well as putting an entry of the users revocation of the certificate in the Certificate Revocation List (CRL). Which connection type is secure and which is a clear text between SSH, telnet and FTP? SSH is the only of the three connection types that supports encryption. Telnet is solely a terminal access type and does not encrypt its payload. FTP is only use for the transfer of data from a server to a client. The solution to a secure transfer was later rectified when Secure Copy (used by SSH) and Secure FTP (SFTP) was developed in order to provide encryption....

...File Transfer Protocol File Transfer Protocol (FTP) is a standard network protocol used to transfer files from one host or to another host over a TCP-based network, such as the Internet. FTP is built on a client-server architecture and uses separate control and data connections between the client and the server. FTP users may authenticate themselves using a clear-text sign-in protocol, normally in the form of a username and password, but can connect anonymously if the server is configured to allow it. For secure transmission that hides (encrypts) the username and password, and encrypts the content, FTP is often secured with SSL/TLS ("FTPS"). SSH File Transfer Protocol ("SFTP") is sometimes also used instead. The first FTP client applications were command-line applications developed before operating systems had graphical user interfaces, and are still shipped with most Windows, Unix, and Linux operating systems. Dozens of FTP clients and automation utilities have since been developed for desktops, servers, mobile devices, and hardware, and FTP has been incorporated into hundreds of productivity applications, such as Web page editors. The original specification for the File Transfer Protocol was written by Abhay Bhushan and published as RFC 114 on 16 April 1971 and later replaced by RFC 765 (June 1980) and RFC 959 (October 1985), the current specification. Several proposed standards amend RFC 959, for example RFC 2228 (June 1997) proposes security extensions and RFC...

...UTILITIES. a. scp and ftp b. ssh and telnet c. rsh and ssh ANWSER: a. Scp is the "Secure Copy" program and it works just like the "cp", or "Copy" program, only it works through via the Secure Shell. Ftp is the "File Transfer Protocol" and has nothing to do with security. Usually operates as its own interface with its own set of user sub-commands. b. Both can be used to control a computer remotely through commands, but Secure Shell (SSH) is more secure than the older Telnet protocol. c. RSH is non-secure; its connections are unencrypted. SSH connections are designed to be secure. 3. explain the client/server model. Give three examples of services on linux systems that take advantage of this model. ANWSER: Well a server provides a shared service/ressource which one or more (usually but not necessarily remote) clients can access.For example:Web server (accessed via a browser on the remote client machine) Mail server (accessed via e-mail program or web-frontend from remote machine) SSH server, DNS server, NTP server and so on and so forth. 5. what is the difference between the world wide web and the internet.

Ftp Download Response Time

...Ethernet Load (Server Load): Ethernet Load can be called also server load. It is presented as a number which values start from 0.00. This procedure represent the number of processes that queuing for getting permission to access the processor(s), which are measured in certain period of time.If a large number of processes occur at the same time the response time is consequently much higher (Lemnaru, 2010). Increasing of a network can have an impact on the server load and Ethernet delay, but this is not the case in some circumstances. The expansion of the network also affects the server load and Ethernet delay. In the Initial simulation (first-floor), carried for this report, consisted 30 workstations which were used over a time period of 30 minutes. Afterwards other 2 groups of workstations, each consisted of 15 workstations, was added. On Figure 5 the first floor scenario (red line), the expansion scenario (blue line) and second floor (green line) are presented. The expansion scenario is higher than first floor scenario. This tendency was expected, as an result of an increase of workstations in the expansion which caused a delay in the Ethernet load. The first floor, second floor and expansion scenario start rising from the same point (0 bits/sec). However, expansion and second floor scenarios reach higher level than first floor scenario, because they have a longer load delay than the first floor. Nevertheless, after reaching the highest pick amplitudes of all 3......

...destination server sent four reply packets back. 6. Find a TCP 3-way handshake for a TELNET, FTP, or SSH session. What is the significance of the TCP 3-way handshake? The TCP 3-way handshake is needed to establish a reliable connection as opposed to an unreliable connection such as UDP. The handshake allows the server and client to agree on parameters that provide for security as well as reliability. 7. What was the SEQ# of the initial SYN TCP packet and the ACK# of the SYN ACK TCP packet? Initial SEQ# is 30 and ACK# is 31. 8. What is the purpose of TFTP and what transport protocol does it use? TFTP, or Trivial File Transfer Protocol, is a simplified version of FTP. It does not require a real logon sequence such as a username and password. TFTP was developed in the 1970s for computers that didn’t have the hardware capability to support full FTP support. TFTP uses UDP to do the file transfers. TFTP is typically used by networking hardware, such as routers and IP phones, to automatically download upgraded firmware without any human intervention via the Internet. 9. Is FTP considered a “secure” file transfer protocol? No, FTP is insecure. However, SFTP, or Secure File Transfer Protocol, was developed in the 1990s. SFTP is FTP via SSL (Secure Socket Layer) to allow for data encryption. A FTP server has to directly support SFTP in order to use SFTP. 10. What other IP packets are on the Ethernet LAN segment? How can these other IP......

The handshake allows client to server communications to agree on security protocols for security and reliability. 7. What was the SEQ# of the initial SYN TCP packet and ACK# of the SYN ACK TCP packet? The SEQ# is 0 for the initial SYN TCP and the SYN ACK is ACK# 1 8. What is the purpose of TFTP and what transport protocol does it use? TFTP is a simple protocol to transfer files. It has been implemented on top of the User Datagram Protocol (UDP) using port number 69. 9. Is FTP considered a “secure” file transfer protocol? Yes it is. FTP is often secured with SSL/TLS ("FTPS").

What happens if you transfer an executable program file in ASCII mode? b. The file will be corrupted: Any bytes that match a NEWLINE will be changed, resulting in a program that will not execute properly. 3. When would ftp be a better choice than sftp? c. When you are sharing public files 4. How would you prevent a local user from logging in on a vsftpd server using her system username and password? d. /etc/vsftpd.conf: local_enable=NO 5. What advantage does sftp have over ftp? e. Ftp is NOT a secure protocol. All usernames and passwords exchanged in setting up an FTP connection are sent in cleartext, data exchanged over and FTP connection is not encryption and the connection is subject to hijacking. A SFTP protocol however, is secure, thus your information is far safer. 6. What is the difference between cd and lcd in ftp? f.

File Transfer Protocol (Ftp)

...File Transfer Protocol (FTP) IT/220 Internet Concepts (AXIA) August 25, 2011 Joseph Sambuco File Transfer Protocol (FTP) If I were a web developer I would use File Transfer Protocol (FTP) to transfer files from one computer to another. There is two ways to use FTP. The first way is to upload files that create a web site from a local computer to a web server. The second way allows the users to download files, programs, and documents from a FTP server that has been already set up. There are Websites that provides links that allow visitors to download files to their computers via FTP. In order for users to download from these sites, they must know the login details. An example of these details could be the username and/or the user password. Once connected there are two ways to transfer the files, the binary mode or the ASCII mode. The binary mode is used for binary files, such as executable programs, music, images, and videos and the ASCII mode is used more for plain text files. Files created in Notepad are examples of the ASCII mode. There are two methods that allow Website developers to establish connections to the FTP server, active and passive. In the active method, the user initializes the connection that commands the port and the server initializes the connection that passes the data. In the passive method, the user initializes the connection for both the command port and passing data. The client and the server will communicate using two ports, one......
