Peter Gregory discusses user account configuration files; adding, modifying, and deleting user accounts with Admintool and shell commands; user shells; and user account commands in Solaris 8.
This sample chapter is excerpted from Sun Certified System Administrator for Solaris 8 Study Guide, by Peter Gregory.This chapter is from the book
After completing this chapter, you'll subsist able to
Identify the following login procedures: log into a system, log out of a system, and change login passwords.
State the command used to identify which users are currently logged into the system.
State the steps required to create user accounts on the local system using the admintool utility.
State the command syntax to add, modify, or delete user/group accounts on the local system with the useradd, groupadd, usermod, groupmod, userdel, or groupdel commands.
Given a user's login shell, list the shell initialization files used to set up a user's labor environment at login.
To fulfill these objectives, this chapter discusses:
User account configuration files;
Adding, modifying, and deleting user accounts with Admintool;
Adding, modifying, and deleting user accounts with shell commands;
User shells; and
User account commands.
Three principal files define the identity of a user account: the password file, the shadow file, and the group file.The Password File
The password file contains the basic identifying information for each user allowed to access a system. The system location of the password file is /etc/passwd. The format of the password file is:username:password:uid:gid:gcos-field:home-dir:login-shell
These fields are:
username—the cognomen that identifies the user account.
password—in Solaris 8 an "x" in this bailiwick signifies that the corresponding shadow file contains the encrypted password string.
uid—the unique numerical ID assigned to the account. The maximum value for UID is 2147483647, but administrators are urged to exercise values less than 60,000 to ensure compatibility with utter of the tools that are used to manage accounts or panoply information that includes usernames.
gid—the primary (default) numerical group ID assigned to the account. love the UID field, the maximum value for GID is 2147483647, but a maximum of 60,000 is preferable.
gcos-field—this is the user's true cognomen (the term "gcos-field" is the historical term for this field).
home-dir—the directory where the user is placed after logging in; this usually contains the user's own files and directories.
login-shell—the initial shell that is started on behalf of the user upon logging in. If this bailiwick is blank, then /usr/bin/sh is used.
The password file can subsist read by anyone on the system. There is no information that must subsist kept covert in this file. A sample password file looks love this:root:x:0:1:Super-User:/:/sbin/sh daemon:x:1:1::/: bin:x:2:2::/usr/bin: sys:x:3:3::/: adm:x:4:4:Admin:/var/adm: lp:x:71:8:Line Printer Admin:/usr/spool/lp: uucp:x:5:5:uucp Admin:/usr/lib/uucp: nuucp:x:9:9:uucp Admin:/var/spool/uucppublic:/usr/lib/uucp/uucico listen:x:37:4:Network Admin:/usr/net/nls: pete:x:100:4:Peter Gregory:/export/home/pete:/bin/sh nobody:x:60001:60001:Nobody:/:
Fields in the password file are delimited by colons (":"), and blank fields are signified by two adjacent colons ("::"). For instance, note that the account cognomen bailiwick for daemon is blank—just two colons. Also, daemon has no shell entry, so the eventual character for daemon is the colon delimiter.
The colon delimiter is likewise used in the shadow and group files, which are discussed in a later section.
It is feasible and permissible to create more than one username in the password file with the same UID. Each username will Have its own unique password. However, tools such as ls and ps, when used with options displaying username, will panoply the first username institute in the password file matching the UID.
When a unique account is added, changed, or removed with the useradd, usermod, or userdel commands (which are discussed later in this chapter), the system creates a backup copy of the password file, called /etc/opasswd.The Shadow File
The shadow file contains each user account's encrypted password, as well as specific per-account parameters governing "password aging." The system location of the shadow file is /etc/shadow. The format of the shadow file is:username:password:lastchg:min:max:warn:inactive:expire:flag
These fields are:
username—this is the same username institute in the password file.
password—a 13-character encrypted password. If this bailiwick contains a lock string (e.g., "locked" or "NP"), the account is inaccessible; if blank, the account has no password.
lastchg—date of eventual password change (literally the number of days between January 1, 1970, and the date the password was eventual changed).
min—minimum number of days allowed before the password can subsist changed.
max—maximum number of days allowed before the password expires.
warn—the number of days prior to expiration that the user is warned.
inactive—the number of days of inactivity allowed for the account before the account is automatically locked.
expire—the date when the user account is deactivated.
flag—a bailiwick reserved for future use.
The shadow file is restricted so that only the system administrator can read it. This is because an intruder could fulfill a "dictionary attack," using guessable passwords in an attempt to determine the passwords for one or more accounts. Programs that "crack" account passwords are available for this purpose; thus, the shadow file is not publicly readable.
A sample shadow file looks love this:root:Pe0iQfp2LcAig:10528:::::: daemon:NP:6445:::::: bin:NP:6445:::::: sys:NP:6445:::::: adm:nIP3GPx2FIZYQ:11053:::::: lp:NP:6445:::::: uucp:NP:6445:::::: nuucp:NP:6445:::::: listen:*LK*::::::: pete:GSSUYVrJ8EKyA:11055:::::: nobody:NP:6445::::::
Note that some of the accounts in the example shadow file Have "NP" ("no password") or "*LK*" (locked) in them. These are just two ways of signifying that the accounts are locked against login. There is nothing really magic about "NP" or "*LK*"—they are just one way of easily showing that these accounts are locked and going to sojourn that way. You could outcome other text in the password bailiwick to suit your needs; for instance, a helpdesk ticket number or a date.
When a user changes his or her password, the system creates a backup copy of the shadow file, called /etc/oshadow. This likewise occurs if root changes a user's password.
Think About It . . .
Why are encrypted passwords institute in /etc/shadow and not in /etc/passwd?
For many commands (ps, ls, etc.) to labor properly, /etc/passwd must subsist world readable. Prior to the exercise of /etc/shadow, utter users' encrypted password strings were likewise publicly readable. This gave people with "password cracking" programs an occasion to discover other users' passwords. By poignant the encrypted password strings to /etc/shadow (which can subsist read only by root), the skill to access encrypted passwords is eliminated.
First, a bit of history. Older versions of UNIX did not Have a shadow file; instead, the encrypted password string was institute in the password file, in the second bailiwick that is usually filled with an "x" in Solaris. Solaris noiseless supports the encrypted password appearing in the password file, although this is not advisable, since the password file is publicly readable.
Older versions of UNIX with no shadow file likewise had no password-aging capability.
The Network Information System (NIS) subsystem was designed around the aged shadow-less architecture; this explains why NIS has no shadow map, nor does it uphold password aging.The Group File
The group file contains a listing of utter of the groups on the system, along with each group's numeric groupid and a list of each of the usernames that are secondary members of each group. The location of the group file is /etc/group. The format of the group file is:groupname:password:gid:user-list
These fields are:
groupname—this is the cognomen of the group.
password—this is an optional password for the group.
gid—the unique numerical ID assigned to the group. The maximum value for GID is 2147483647, but administrators are urged to exercise values less than 60,000 to ensure compatibility with utter of the tools that are used to manage accounts or panoply information that includes group names.
user-list—a comma-separated list of users allowed in the group. These groups are users' secondary group IDs.
A sample group file follows.root::0:root other::1: bin::2:root,bin,daemon sys::3:root,bin,sys,adm adm::4:root,adm,daemon uucp::5:root,uucp mail::6:root tty::7:root,tty,adm lp::8:root,lp,adm nuucp::9:root,nuucp staff:GSSUYVrJ8EKyA:10:pete daemon::12:root,daemon sysadmin::14: nobody::60001: noaccess::60002: nogroup::65534:
Note the password bailiwick in the group "staff." Groups can subsist password protected by putting a password string into the password field. Note, though, that this is a completely manual process; there are no tools provided to outcome the group password in for you.
Hint: You can occupy a password string from the shadow file and exercise the vi editor to splice it into the group file. The group password will subsist the same as the account password from the shadow entry where you took the password string.
When a group is password protected, anyone who is not a member of the group will subsist challenged for the group's password when they Have entered the newgrp command.Primary and Secondary Groupids
Each user account has one primary groupid—this is the group defined in the password file. When a user logs on, this is his or her associated groupid.
Each user account likewise has zero or more secondary groupids. A user's secondary groups are those group entries that include the username in their lists of members.
There are some useful limitations of groupids. For example, each user account can subsist in no more than 16 groups, and a line in the group file cannot exceed 512 characters (including the newline character).
What happens if you need to add so many members to a group that you exceed the 512-character entry limit? You simply create another duplicate group entry—same cognomen and group number—and list the additional members there.
The primary and secondary groupids directly impact file system access permissions, which is explored fully in Chapter 10.
Think About It . . .
What would subsist the outcome if a username were added to a group file entry when that group was the user's primary group?
The additional entry would Have no effect, since the user is already configured for the primary group membership in the /etc/passwd file.The Root Account
The root account has special privileges on a system: Root is permitted to read and write every file on a system, regardless of the file's ownership and leave settings. System administrators log in with the root account so that they can fulfill administrative tasks.
The root account gets its power and privilege from the value of its user number: Root is user number zero, defined in the password file.
Think About It . . .
What would subsist the effects of changing an ordinary user's user number to zero? What advantage might there subsist of putting root's entry at the near of the passwd file (instead of the beginning)?
Changing an ordinary user's user number to zero gives the user root privileges.
One advantage of putting root at the near of the password file is that if an intruder is able to modify the password file to give another user root privilege (see the first question here), then output from commands such as ls and ps would present that other user as the owner of root processes and files.
