Managing User Accounts In Linux Essay

Linuxs most worthy advantage over other operating systems such as Windows and macintosh is security and in order for a lend oneselfr to qualify vital components of the system, such as drug substance abuser accounts, is to have access rights of a ROOT. The go under is at the top level of Linuxs user hierarchy and has alone the privileges to access all resources. To login as root, a user must use the control condition su username. After pressing the ENTER key, the system will incite the user to type in the corresponding give-and- dispense. After entering the reclaim password, the user will inherit full access privileges including the right to modify other users account entropy.Attempting to enter the correct password will deny the user from inheriting the roots privileges. su screenshot permit us now attempt to take a crap a raw(a) user called clown. tho first, let us check if that username is not stock-still taken. id slit screenshot Since username bozo is still available we can now pretend his user account. useradd bozo -d /home/bozo -u 600 We have just created a username called bozo and makes his default folder under /home/bozo and gave him the UID of 600. by the way, UIDs be unique identifiers of users.Users can be a way of both human users and services running in the Linux system. UIDs are used by Linux in relation to his password and privilege information stored in the /etc/passwd, /etc/shadow and /etc/group. One of the very first thing Linux does when creating a sunrise(prenominal) user is to copy the files from the skeleton folder, which contains whatever files the admin wants to give to new users, into the newly created users folder. forthwith, let us try to take a look at those files by displaying a detailed inclination of files including hidden ones. ls la /home/skel/ So far so good. Now let us try creating another user and call her bozoette. useradd bozo -d /home/bozo -u 600 We had an error. As stated earlier, UIDs are un ique. Since we attempt to create a user and assigned the same UID with bozo, the system denied our request. But what if we do want give bozoete the UID 600? One of the many ways to do it is to first change bozos UID, say 601 and then create bozoettes user account exploitation the newly-vacant UID of 600. Change bozos UID from 600 to 601. id bozo usermod -u 601 bozo id bozoThen create bozoettes new account with UID 600. useradd bozoette -d /home/bozoette -u 600 Now we have two new users bozo(uid601) and bozoette(uid600) with user directories /home/bozo and /home/bozoette, respectively. Note that user accounts remain soundless until a password is assigned to them. Let us now air the two new user accounts by assigning passwords to them. passwd bozo passwd bozoette Users bozo and bozoette are now active and users can now login to the system using the correct username and password combinations for the accounts.REFERENCES Linux Headquarters.
