Example -- Setting Protection Level in ftp
Now suppose that joe wants to use ftp to get his mail from the directory ~joe/MAIL from the machine denver.example.com, encrypting the session. The exchange would look like this:
% ftp -f denver.example.com Connected to denver.example.com 220 denver.example.org FTP server (Version 6.0) ready. 334 Using authentication type GSSAPI; ADAT must follow GSSAPI accepted as authentication type GSSAPI authentication succeeded Name (daffodil.example.org:joe) 232 GSSAPI user joe@MELPOMENE.EXAMPLE.COM is authorized as joe 230 User joe logged in. Remote system type is UNIX. Using BINARY mode to transfer files. ftp> protect private 200 Protection level set to Private ftp> cd ~joe/MAIL 250 CWD command successful. ftp> get RMAIL 227 Entering Passive Mode (128,0,0,5,16,49) 150 Opening BINARY mode data connection for RMAIL (158336 bytes). 226 Transfer complete. 158336 bytes received in 1.9 seconds (1.4e+02 Kbytes/s) ftp> quit % |
To encrypt the session, joe sets the protection level to private.
