The /etc/passwd file is a text file you can edit using a text editor. You can change fields in entries and even add new entries. The only field you cannot effectively change is the password, which must be encrypted. To change the Password field, you should always use the passwd command. Although you can make entries directly to the /etc/passwd file, an easier and safer way is to use the userconf, adduser, and useradd utilities. These programs not only make entries in the

/etc/passwd file, but they also create the home directory for the user and install initialization files in the user's home directory. The /etc/passwd file is a simple text file and is vulnerable to security breaches. If anyone gains access to the /etc/password file, they might be able to decipher or brute force crack the passwords. On most Linux distributions , the shadow suite of applications implements a greater level of security. These include versions of useradd, groupadd, and their corresponding update and delete programs. Most other user configuration tools support shadow security measures. With shadow security, passwords are no longer kept in the /etc/password file. Instead, passwords are kept in a separate file called /etc/shadow and are heavily encrypted. Access is restricted to the root user. A corresponding password file, called /etc/gshadow, is also maintained for groups that require passwords. As part of the standard installation for Red Hat, shadow passwords were implemented by default. You can manually specify whether you want to use shadow passwords with the authconfig tool in the Text Mode Setup utility. Note authconfig is a text mode tool that you can use to enable and configure various authentication tools such as NIS and LDAP servers, as well as enabling shadow passwords, LDAP, and Kerberos authentication. On Red Hat, authconfig will generate the /etc/pam.d/system-auth configuration file use for system services.

Each time a user logs in, two profile scripts are executed. A system profile script is the same for every user, and each user has the .bash_profile script in his or her home directory. The system profile script is located in the /etc directory and named profile with no preceding period. As a superuser, you can edit the profile script and put in any commands you want executed for each user when he or she logs in. For example, you may want to define a default path for commands, in case the user has not done so. Or, you may want to notify the user of recent system news or account charges. When you first add a user to the system, you must provide the user with a skeleton version of their login, shell, and logout initialization files. For the BASH shell, this would be a .bash_profile .bashrc and .bash_logout files. The useradd command and other user management tools like User Manager add this file automatically, copying any files in the directory /etc/skel to the user's new home directory. The /etc/skel directory contains a skeleton initialization file for .bash_profile, .bashrc, and .bash_logout files or, if you are using the TCSH shell as your login shell, .login, .tcshrc, and .logout files. The /etc/skel directory also contains default files and directories for your desktops. These include a .screenrc file for the X Window System, a .kde directory for the KDE desktop, and a Desktop directory that contains default configuration files for the Gnome desktop. As a superuser, you can configure the .bash_profile or .bashrc files in the /etc/skel any way you want. Usually, basic system variable assignments are included that define pathnames for commands and command aliases. On Red Hat, the PATH and BASH_ENV variables are defined in .bash_profile. Once users have their own .bash_profile or .bashrc files, they can redefine variables or add new commands as they choose. The .bashrc file will also run the /etc/bashrc to implement any global definitions such as the PS1 and TERM variables. The /etc/bashrc file also executes any specialized initialization file in the /etc/profile.d directory

such as those used for KDE and Gnome. The .bash_ profile file runs the .bashrc file, and through it, the /etc/bashrc file, implementing global definitions. System-wide values used by user and group creation utilities like useradd and usergroup are kept in the /etc/login.defs file. Here you will find the range of possible user and group IDs listed. UID_MIN holds the minimum number, and UID_MAX the maximum number for user IDs. Various password options control password controls- such as PASS_MIN_LEN, which determines the minimum number of characters allowable in a password. Options such as CREATE_HOME can be set to tell useradd to create home directories for new accounts by default. login.defs
