I encountered a question in the Redhat Skills Assessment regarding useradd: Which of the following cannot be defined when you create a user account with useradd?
a* A password expiration date.
b* The user's primary group.
c* The user's default shell.
d* The user's NIS or LDAP group.
e* The user's home directory.
Which is the correct answer? I have my own thinking which will be explained later.
How can I add user on LDAP to my Linux server ?

The first time when I add this user I was successful.Later I deleted this suer using the userdel -r ajit command.Now when again I am trying to add this user it gives me following error. useradd: group ajit exists - if you want to add this user to that group, use -g.

I recently created a new user account in ubuntu linux, and created a file called xsession so that I can boot directly into xmbc when I log into that account. Is there anyway to delete the home folder for that account. I can view the file but when I try to delete it is says I do not have apporite permisions to delete the file.
I removed the account and deleted the group but it still shows up when I type in the address /home/xmbc
Is there anyway I can delete this file. It also will not let me create any new user accounts is there any way I can fix these prolbems without totaly reinstalling the system.
I've got several large files sitting in my linux hosted account that I need to upload to my S3 account. I dont want to download them first and then upload it into S3. Is there any way I can "upload" it via the linux command line environment? Or access it via a website working with lynx?

The reason I want a root account in Salix because I believe in freedom of choice, and my choice always was and always will be to have a root account set up so I can login as root. I am aware of the risk involed in creating a root account.

I am looking into creating my own terminal command from scratch. I researched online for some information on this subject was only able to view stuff related to OS X. I understand that they are both Unix based, are they both similar in creating these commands? Basically all I would like is for someone to point me towards the right direction to start or complete this task.

Where Sdb is my USB
The copy operation is okay...It says no of records in / out and gives the statistics
But when I boot the system , getting the error:
Boot :
In some cases , the USB itself is not recognized by BIOS at boot..
My BIOS supports boot from USB ..I have Boot order 1. CD/DVD 2. USB 3. HDD
Also what is the filesystem to be adopted for dd?
I usually format using FAT or FAT 32
1.mkfs.vfat /dev/sdb -I (or)
2.mkdosfs /dev/sdb (or)
3.mkdosfs -F 32 /dev/sdb
What is the correct way of partitioning USB drive? - FAT or FAT 32....Most Live USB creators (unetbootin/LiLi Live/Usb Creator) recognize only FAT32...
I dont want a Linux filesystem (ext2,ext3 or 4or reiserfs)for my USB as it is not portable across many systems as MS OSes do not read them..Also I had little success in booting a USB when I partitioned it using ext2..I read somewhere that ext2 will not reduce the life of the USB drive compared to other fs.
I am at my own desktop and I have root access on my own desktop.
I also have root access on a Desktop Ubuntu system (192.168.5.10) on the LAN. I need to create another desktop user account on that 192.168.5.10 system.
So I logged into that system with: ssh -Y myself@192.168.5.10
Then I did: sudo users-admin
This brings up the Users Settings but the Add User and Unlock buttons are disabled. How do I enable these buttons?

I'm trying to create a user john with default password 'abcdef'. I used the following command.
useradd john -p abcdef
I can't login with the password. in /etc/shadow file I can see the password in clear text format. how I can create a user along with password.
Is there a non-root shell command that can tell me if a user's account is disabled or not? note that there is a fine distinction between LOCKING and DISABLED:
LOCKING is where you prepend ! or * or !! to the password field of the /etc/passwd file. On Linux systems that shadow the passwords, this marker flag may be placed in /etc/shadow instead of /etc/passwd. Password locking can be done (at a shell prompt) via password -l username (as root) to lock the account of username, and the use of the option -u will unlock it.
DISABLING an account is done by setting the expiration time of the user account to some point in the past. This can be done with chage -E 0 username, which sets the expiration date to 0 days after the Unix epoch. Setting it to -1 will disable the use of the expiration date.
The effect of locking to to prevent the login process from using a supplied password to hash correctly against the saved hash (by virtue of the fact that the pre-pended marker character(s) are not valid output character(s) for the hash, thus no possible input can ever be used to generate a hash that would match it). The effect of disabling is to prevent any process from using an account because the expiration date of the account has already passed.For my situation, the use of locking is not sufficient because a user might still be able to login, e.g. using ssh authentication tokens, and processes under that user can still spawn other processes. Thus, we have accounts that are enabled or disabled, not just locked. We already know how to disable and enable the account - it requires root access and the use of chage, as shown above.To repeat my question: is there a shell command which can be run without root privileges which can output the status of this account expiration info for a given user? this is intended for use on a Red Hat Enterprise 5.4 system.The output is being returned to a java process which can then parse the output as needed, or make use of the return code.
I recently used the newusers command to generate several user accounts from a text file. That process seemed to go well until I tried to su into one of the new accounts.
This behavior appears for all the accounts that were created from the text file and the newusers command. It seems that several configuration files that should have been autogenerated for these new users were never created. I was able to confirm this was the problem by copying .bashrc and .bash_profile from a user that was created with the "useradd" command into the /home/newaccount directory. After logging off and logging into the newaccount again, the issue is corrected.For the record, I just read this forum post and I'm looking for an alternative to this. If this is the most efficient way to accomplish my goal, then I'll try the route mentioned in the thread. I'm still open to alternatives.
I can do:mkdir messages and then: touch messages/hello.txt Is there a command that will do both - create the directory if it doesn't exist, and then the empty file? Something like: touch -p messages/hello.txt
