Very Computer

I've been struggling with this ftp login failure problem for
a month and still no clue.  Here is the symptom:  I login
as a regular user with login password and always get the
following

Connected to host.domain
220 host.domain FTP server (Version wu-2.5.0(1) Tue Sep 21 16:48:12 EDT
1999) ready.
Name (host:me): me
331 Password required for me.
Password:
530 Login incorrect.
Login failed.
ftp> quit

I thought the problem might be because /etc/shadow was missing
in my initial installation of RedHat 6.1 and ftpd (or in.ftpd)
needs to check this file, so I created /etc/shadow using pwconv.
It didn't solve the problem.  Then I checked /dev/tty, the mode
is 666, fine.  In /var/log/message and secure, it logged
ftpd[_number_]: cmd failed, nothing more than that.  So I am
speculating that ftpd somehow failed to get the password
correct for any given user.  What else could possibly be wrong?

Thanks.

If the user is root there is another mechanism which keeps you from logging in via simple services. I don't know the way to disable that off the top of my head but you can just create a normal user that does _not_ have root access [does not belong to group root] and they can get in just fine. You can also telnet in with that user then use "su" to become root.
