[4]
MacTerminal was the first telecommunications and terminal emulation application software program available for the Mac.MacTerminal enabled users to connect via modem or serial port to bulletin board systems and online services (e.g., The Source, CompuServe), and to other computers.
On modern Linuxes, information on shell built-in commands can be found by executing help, help [built-in name] or man builtins at a terminal prompt where bash is installed. Some commands, such as echo , false , kill , printf , test or true , depending on your system and on your locally installed version of bash, can refer to either a shell ...
These permissions can usually be adjusted only after authenticating with the password. This can be a useful form of delegation of authorization, for example, when creating programs that will access the remote system. The PAT will typically be stored in a location accessible to the program, and therefore not typically as secure as a password.
DaveGrohl supports all of the standard Mac OS X user password hashes (MD4, SHA-512 and PBKDF2) [1] [2] [3] used since OS X Lion and also can extract them formatted for other popular password crackers like John the Ripper. [4] The latest stable release is designed specifically for Mac OS X Lion and Mountain Lion.
TERM : specifies the type of computer terminal or terminal emulator being used (e.g., vt100 or dumb). PS1 ( Unix-like ): specifies how the prompt is displayed in the Bourne shell and variants. MAIL ( Unix-like ): used to indicate where a user's mail is to be found.
20] In this example, the sender of a message runs it through a MAC algorithm to produce a MAC data tag. The message and the MAC tag are then sent to the receiver. The receiver in turn runs the message portion of the transmission through the same MAC algorithm using the same key, producing a second MAC data tag.
ssh-keygen is a standard component of the Secure Shell (SSH) protocol suite found on Unix, Unix-like and Microsoft Windows computer systems used to establish secure shell sessions between remote computers over insecure networks, through the use of various cryptographic techniques.
