[SOLVED] Setting a password with useradd, and questions about groups

Hello,

Until now, I used to add users to my system using the adduser script. But I recently found out the useradd command which seem more convenient to me.
But I have a problem with it, even after reading the manpages.

The command I run as root is:

useradd -g users -G storage,optical,network,audio,video -m mylogin

Then I logout, and try to log in as mylogin, but the prompt ask me for a password (I haven't set it...). If I leave blank and type enter, it says that my password is incorrect.

I also tried:

useradd -g users -G storage,optical,network,audio,video -p mypassword -m mylogin

Then I logout, and try to log in as mylogin, the prompt ask me for a password, I type mypassword and type enter, but it says once again that my password is incorrect

The last question I would like to ask is: What are the groups that I really need for my desktop ? (I could add a lot of them, but I'm interested in understanding what I do)

Do I need storage for accessing my partitions ? Do I need optical to read/burn DVD ? Do I need network to use networkmanager ? Do I need audio to listen to music ? video to watch 1080p movies with VLC on my Intel i3 chipset ?

Thanks a lot :]

passwd: set/change user password.

usage:

passwd username

I know about passwd, but it'll be much more easier if I could define the password while creating the account, and not have to change it afterward

Re: [SOLVED] Setting a password with useradd, and questions about groups

How did you generate the password?  According to the manpage it needs to be encrypted when you use the -p flag.  If you enter a text string (e.g. mypassword), it will be added to shadow as text, which won't work.

Re: [SOLVED] Setting a password with useradd, and questions about groups

the preferred way is to use listed statements in the shell
useradd foo && passwd foo

to answer your questions on groups, it depends entirely on how you've set up your system
a good starting point is the wiki article linked to in JokerBoy's post

@loafer: You were right. I entered mypassword directly without any encryption, I guess it was the cause of the problem :]

@fsckd: Thank you, it worked perfectly !
