I just install ubutnu server 10. I'm sitting at the cli trying to add a new user. I am getting the following error:

useradd: cannot lock /ect/passwd; try again later

Any suggestions??? I'm just trying to add a new user!

are you running the useradd as a admin ?

do a 'sudo useradd ..... '

Administrative tasks such as adding users require elevated privileges. On Ubuntu, you use the sudo command to elevate your privileges. You will be prompted for your currently logged in user account password when you run the command.

sudo useradd username

is there a way for me to get a list of the users on the server? After I typed in the sudo useradd username it just went to the next cli line with no other promps or messages

you have two ways (potentially more)

sudo cat /etc/passwd


there is

sudo lastlog

which will list your users, plus the last login times etc

thats perfectly normal - the command completes with no output. You can use command line switches to set other options, or use usermod to change things post-creation.

Okay, I see my many many many users I've added trying to get this going...

I thought I would be prompted to set a password for the users when I created them but I wasn't. I'm typing in:

sudo useradd doej

I've googled & thought I could add a -p password to the end but this in not working.

just run a sudo passwd username to set the password.

You cant do it that way around AFAIK - you can see what groups users are part of, and look at file system permissions, but you cant see a joined up list of users v's permissions.

list all your groups with

sudo groups

or list what groups someone is in with

sudo groups username

then you would have to look at file system permissions and check manually.
