Notes on Chapter 2 UNIX- FJW 01/21/03

Two types of UNIX accounts: root (or superuser account created automatically) and user accounts
(Solaris- keep ID 8 characters, Password at least 6 charaters. They are case sensitive)
Note: When typing a password, it is possible that no characters appear, not even ******
rlogin, for "remote login"
CDE= Common Desktop Environment. It has Login Manager Options- Session option gives choice of GUI desktop environments (CDE or Open Windows) and a Failsafe login option
Ctrl+u to 'undo'
Logging out prevents unauthorized users from gaining access; not necessary to shut down the typical UNIX computer because these computers are designed to be left running. 
To Telnet (remotely login) to another system, the IP address or host name of the remote UNIX workstation or server must be specified. 
On most systems, Ctrl+d can be used to log out or exit a Telnet Terminal window.
UID= user identification number assigned by the system administrator. 
GID= primary group membership number
$ id - to find UID number, username, GID number, and group name for an account.
$ init 0 or the shutdown - Shut down the system (system initialization state of 0 is off)
$ su - login as root or switch to the root account
$ passwd - to change a password (case sensitive, spaces ARE permitted)
The Terminal window gives the user access to a command line $ prompt
