  1. Configuring a LAN FTP Client Chapter 17 & 19

  2. Setting up the physical layer • Chapter 17 covers the basics of hubs, switches, routers and WAPs.

  3. Configuring the systems • Kudzu: detects NIC and configures new hardware • System-config-network

  4. FTP: Transferring Files Across a Network Chapter 19

  5. FTP Introduction • File Transfer Protocol • ftp – not secure • sftp – component of OpenSSH • vsftpd – server side runs without the use of the root security context

  6. FTP Client • Connecting to the server • ftp hostname • View files with the “ls” command as you would normally do • Navigate using “cd”

  7. FTP: moving files • “put” command • Command for uploading from the client to the server • put timesheet.xls • “get” command • Downloads from the server • get memo.txt

  8. FTP commands • Working with multiple files • mget command can be used to retrieve multiple files • mget * - will retrieve all files in a directory • mget *.doc will get all MSWord docs • You will be prompted to confirm mget commands. You can shut this off with the “prompt” command

  9. Other useful FTP commands • lcd [local_directory]- allows you to control the directory you are working from/to • delete file_name – allows you to delete the file on the server (mdelete = multiple) • pwd – print working directory of server • !pwd – print working directory of local host • bye – leave the server (also quit)

  10. FTP Server Side • Prereqs: • Install ftp server package (vsftpd) • Configure ftp server to start when system enters multiuser mode • # /sbin/chkconfig vsftpd on • Start vsftp • # /sbin/service vsftpd start • To test status - # /sbin/service vsftpd status

  11. Anonymous FTP • By default users log onto the ftp server with anonymous access. • When connected the default working directory on the server will be “/var/ftp” • For the ftp session this will be considered the user’s home directory on the server. • The user will only see that they are in “/” • This is referred to as “chroot jail”

  12. ftp put permissions • Before any user can upload they will require write permissions on the directory • Chmod will work here for that purpose

  13. Exercise • Take a moment to google some poplar ftp client software • What are some popular ftp server programs? • Install the vsftpd package on you machine and test
