  11. Communication through SLIP/PPP connection Bruce Rong

  12. Remote Communication • PPP (Point to Point Protocol) • SLIP (Serial Line Internet Protocol) Bruce Rong

  13. Serial Line Internet Protocol (SLIP) • SLIP is the earlier technology • Deficiencies • no addressing • no type identification • no error detection/correction • no compression Bruce Rong

  14. Point to Point Protocol (PPP) • PPP is newer and has more capabilities over SLIP • designed for simple links which transport packets between two peers • provide full-duple simultaneous bi-directional operation Bruce Rong

  15. Point-to-Point protocol a common solution • Encapsulation • provides for multiplexing of different network-layer protocols simultaneously over the same link • Link Control Protocol (LCP) • handles varying limits on sizes of packets • detect a looped-back link and other common misconfiguration errors, and terminate the link • Network Control Protocols (NCP) • exacerbate many problems with the current family of network protocols such as assignment and management of IP addresses.

  17. Remote Communication SLIP/PPP allows a user with a personal computer, such as a Macintosh or a PC, and a modem to connect to the Internet, without having to first log on to a remote machine. This capability enables the user to make use of Internet applications and tools such as telnet, file transfer (ftp), electronic mail, and graphical web browsers directly on hisor her personal computer. Bruce Rong

  18. How does SLIP/PPP connection works • A user's modem dials up a remote computer at an Internet Service Provider (ISP). • The SLIP/PPP software requests a SLIP/PPP connection. • Once the connection is made, the service provider assigns the user's computer an IP address (in the case of a service provider who assigns IP addresses "on the fly"). • The TCP/IP software on the user's computer "takes over" and manages the flow of data between the Internet and the user's computer. Bruce Rong

  19. Remote Authoring and Management Applications • Front Page 2000 • a big improvement collaboration features • IIS (Internet Information Server) • brings the power of scalable, component-based client/server applications to the Web. Bruce Rong

  20. Internet Information Server(IIS) • Microsoft Windows NT Server’s built-in Web server. • Integrated message queuing • provides a reliable send and receive messages over a network • Security • using Server Gated Crypto it offer the strongest (128 bit) encryption for its online transactions Bruce Rong

  21. Front Page 2000 • Publish Anywhere • build in FTP support • Check In/Check out • team work made easy, user can reserve a file only can be edit in FrontPage • Administer FrontPage-based Web sites remotely using standard HTML Bruce Rong

  22. Summery • SLIP and PPP are protocols, or rules, that allow a computer to simulate a direct connection to the Internet. A computer with SLIP or PPP uses a modem to dial in to an Internet Service Provider and establish a SLIP/PPP connection. The SLIP/PPP software and the TCP/IP software on the user's computer work together to manage the connection and oversee the movement of data packets between the Internet and the user's computer. • A SLIP or PPP connection facilitates the use of Internet applications and tools, such as telnet, file transfer, electronic mail, and graphical web browsers directly on the user's computer, thereby providing the user access to the full spectrum of the Internet's graphical offerings, such as multimedia, sound clips, photographs and animation. Bruce Rong

  23. File Transfer Protocol (FTP) Elizabeth Chang

  24. What is it? File transfer protocol (FTP) • file transfer means to copy files from one system to another • protocol is a special communication language designed for efficient transfer of files Elizabeth Chang

  25. FTP Usage • FTP programs are tools that enable you to upload and download programs, sounds, pictures, and even movies from remote computers. • Allows you to examine the files on a remote host computer, select the files you desire and transfer them to your computer. http://www.schoolpositions.com/savvy/ftptut.html Elizabeth Chang

  26. FTP Usage (continued) • To download/upload files to create or update a Web site. • Delete • Rename • Create directories • Move • Copy Elizabeth Chang

  27. What is it based on ? • Client server model - one computer acts as a client, which sends instructions to the other computer, known as the server - File transfers can go both ways - Client initiates the transfer - Server must be in between the clients Elizabeth Chang

  28. FTP requires two participants • FTP client program : what we run on our computers • FTP server : is the program that runs on the huge mainframe somewhere at a remote site which contains a lot of files. Elizabeth Chang

  29. FTP clients (connects to FTP server) • Command-line clients : are generally found on UNIX systems and others that provide “shell” accounts • UNIX “shell” accounts - for the name of the part of UNIX that listens to the commands you type • Graphical clients : provide a windowed interface http://www.dragonfire.net/ftp.html Elizabeth Chang

  30. FTP Servers (stores files) • They transmit messages to let you know (or your client program) know what’s going on. • Use to handle the distribution of various files: free programs, product documentation, or data files • FTP servers are independent of the Web and supply other files other than the ones listedon Web pages Elizabeth Chang

  31. Transferring Files of Different Types ASCII (text file) • Mac, Windows, & UNIX have different conversions for storing text files. • Automatically adjusts the file during the transfer so that the file is a valid text file when stored on the receiving end. Elizabeth Chang

  32. Different types (continued) Binary (image mode) • Sends the file exactly as it is • No changes at all • It is left alone and transferred verbatim • Capable of sending any file not just text (graphic files,audio files, video files, programs and any other kind of file other than plain text) Levine Young, Margaret. The Complete Reference: Internet Millennium Edition. Worldwide Books Elizabeth Chang

  33. FTP software Programs with graphical user interface: • WS_FTP (http://www.ipswitch.com) • CuteFTP (http://www.cuteftp.com) • FTP Explorer (http://www.winsite.com) • Fetch (Mac) • Anonymous FTP Elizabeth Chang

  34. FTP Software (continued) Web browsers: Microsoft and Netscape browsers, include basic FTP client capacity Command-driven: UNIX and Windows 98 come with a more capable FTP client program, called Ftp (to use, you must type commands) Elizabeth Chang

  35. FTP and remote web management • FTP is the simplest way to exchange files between computers on the Internet • Uses the Internet’s TCP/IP protocols • Commonly used to transfer Web page files from their creator to the computer that acts as their server for everyone on the Internet • Easy and effective means of managing a web site http://whatis.com/ftp.htm Elizabeth Chang

  36. Telnet Telecommunications Network Protocol Teresa Cisneros

  37. When to telnet • Checking e-mail • from any computer on the Internet • Users can telnet in to their ISP’s server • When maintaining a Web site • Clean up files and update the site Teresa Cisneros

  38. Review Definition of Telnet: Telnet lets you connect to a remote computer and then use that computer as though you were sitting at a plain terminal directly connected to the remote host. Teresa Cisneros

  39. Points to be discussed: • How to log in to your ISP server via telnet • How to organize your web site files • How to rename files, delete unneeded files, fix file permissions and do other tasks related to your web site maintenance • Different telnet programs available Teresa Cisneros

  40. Logging in to your ISP Server 1) Connect to the Internet 2) Run a Telnet Program & tell it to connect to the host computer (ISP Server) 3) ... Teresa Cisneros

  41. Continue…Logging in to your ISP Server 3) A dialog with the host computer appears in the telnet window and you log in to the host computer 4) When you are done making the neccesary changes to your Web site you disconnect from the host computer. Teresa Cisneros

  42. Once you are logged in to your account you can... • List your files • Change the current directory • Rename, copy, and delete files • Display file permissions • Change file permissions • Display files for changes and updates Teresa Cisneros

  43. Listing your Files • To see a list of the files in the current directory, type ls and press ENTER. Teresa Cisneros

  44. Changing the Current Directory • To move to a directory, type chdir or cd followed by a space and the name of the directory to move to. • To move back to your home directory type chdir or cd with no directory name Teresa Cisneros

  45. Renaming, Copying, and Deleting Files • To rename a file in the current directory, type mv followed by a space, the current file name, another space and the new file name. • To see what is in a file, you can use the more command Teresa Cisneros

  46. Displaying File Permissions • Types of permissions • Read permission • Write permission • Execute permission Teresa Cisneros

  47. Some Telnet Programs Teresa Cisneros

  48. NetTerm • Also available from ftp.neosoft.com/~zkrr01 • One of the best telnet clients available on the Net. • Very user friendly aneasy to use. Small and loads quick. • Also userful to those looking not to use a lot of disk space. Teresa Cisneros
