useradd with * in passwd field

2009-04-06 Thread Sudarshan Soma
Hi All,
I need to add a user who will have entry in the /etc/passwd file as
below,  where the passwd field is marked as *

myuser:*:12:23:guest:/:/bin/bash

I need to do this by using command useradd, but i am not able to find
easier way to do this by commands other than manually editing passwd
file.


The intention is to create a user with whcih login can never happen
Please suggest

Thanks and Regards,
Pavan

Thanks Chris.
I got the command ,
usermod -p * user   /dev/null

Actually i want to make user with no access at any time.

Best Regards,

 Hi Pavan,

 First, you should in almost all cases have shadow password support
 enabled, so the actual passwords will be in /etc/shadow not /etc/passwd.

 Second, useradd will by default create an account which cannot be
 accessed until a password is added (typically with the passwd command).
 If you need to lock an account that has a password so that it cannot be
 used for login, you can use passwd -l username; note that this
 prepends an exclamation mark to the password field (does the same thing
 as your star). The opposite command is passwd -u username, which
 unlocks the account.
