[NTLUG:Discuss] Default password?

[Paul Ingendorf]

At the risk of being proven a moron I'm pretty sure this would have to be done via a program at login to make them change it.  However I know you can set password timeouts on most all systems I've ever seen post shadowing anyway.  Speaking of which a quick passwd --help showed the following which should answer your question.

#passwd --help
Usage: passwd [OPTION...] <accountName>
  -d, --delete           delete the password for the named account (root only)
  -f, --force            force operation

  -k, --keep-tokens      keep non-expired authentication tokens
  -l, --lock             lock the named account (root only)
  -S, --status           report password status on the named account (root
                         only)
  --stdin                read new tokens from stdin (root only)
  -u, --unlock           unlock the named account (root only)
  -i, --inactive=INT     set the number of days after a password expires, that
                         the account becomes inactive (root only)
  -x, --maximum=INT      set the maximum number of days a password remains
                         valid (root only)
  -n, --minimum=INT      set the minimum number of days before a password may
                         be changed (root only)
  -w, --warn=INT         set the minimum number of days warning that a
                         password needs to be changed (root only)
  -g, --group            manipulate group password - passes to gpasswd
  -r                     used only to pass to gpasswd
  -R                     used only to pass to gpasswd

Help options:

  --usage                Display brief usage message

I agree.

Now let me modify the question somewhat and see if anyone knows this password 
question.  Lets say I create a new user, set a default password, but want to 
force the user to change the password next time he logs in.  I don't want to 
set any expiration time range (like he must change it every 30 days), I just 
want him to change it at his next log in, be it today or next week.  On 
Solaris, I'd do that with "passwd -f user", but I can find no equivalent for 
Linux.  Anyone?
