    In a HOWTO page, I'm told to define a new user this way:
    (I'm using Debian Sarge 3.1 Official)
    1. Create new group ppp, for this you need to edit file /etc/group and add this line on the end of file:


    2. Create new system user for dialin connection pppuser: Simple create new system user and when using shell command vipw change line of user pppuser to this:


    3. Use Passwd command to change the password to whatever you want.

    When I typed
    passwd pppuser (return)
    I got the following error:
    passwd Authentication service cannot retrive authentication.

    What's wrong?

    I don't why but, when I emailed the auther and asked to use "adduser". He told me not to !! And told me again to follow those steps:
    follow 1 and 2 step, not using adduser and then change password using
    command passwd to whatever you want.

    The line should read:


    I got rid of the x after "pppuser:"

    Where you have x that is where the md5 hashed password goes. You might be confusing the authenication to thinking you actually have a nonstandard password.

    As always you'r right dduardo :D
    The problem solved but still I can't login.
    I followed the structions on the page:
    http://tvilda.stilius.net/callback_en.php [Broken]
    But when I want to dial from a win box, I get Access denied, the user or pass is unknown on the domain.

    Did you restart pppd when you changed the password?

    /etc/init.d/pppd restart

    Also, I would try from another linux box to try to dial into the server using kppp or something similar. Windows can be funny with authentication.

    You know, I think one of the most important tasks of a good programmer is to restart his machine at least once in a hour :D Whenever I changed the configurations I either typed "init q" or restarted the machine.

    You know when I set the pppd without "login" option. It works well. It shows that I'm very close to it. But without authentication all that I've done in last 3 days is nothing :((

    I tried to connect via a linux box as ddura told me. The authentication failed again :((

    Can you login to pppuser from the server directly?

    su pppuser

    Tomorrow I'll check it with "su". But I tried to login in a terminal directly, I don't remember exactly but it was something like this:

    Debianserver $: login: pppuser
    Debianserver $: password: 123
    Debianserver $: pppd: the remoet client must athenticate itself
    Debianserver $: pppd: but I can't find any secret(password) for it

    Debianserver: login:
