But you did say something about passwd in there I found this..
But I dont know what it means:
root:x:0:0::/root:/bin/bash
bin:x:1:1:bin:/bin:
daemon:x:2:2:daemon:/sbin:
adm:x:3:4:adm:/var/log:
Can someone tell me about it?
Syntax of lines in /etc/passwd is:
username:passwordhash:uid:gid:undefined:homedir:loginshell
When the password hash is x, that means it's stored somewhere else, possibly /etc/shadow. It's not stored plaintext, but as an unrecognizable hash. When someone tries to login, it hashes what they type and compares the hashes.
You don't edit any of these files yourself, you use the passwd command. See 'man passwd'.

ftpusers
ftpusers(4) File Formats ftpusers(4)
NAME
ftpusers - file listing users to be disallowed ftp login privileges
SYNOPSIS
/etc/ftpd/ftpusers
DESCRIPTION
The ftpusers file lists users for whom ftp login privileges are disallowed. Each ftpuser entry is a single line of the form:
name
where name is the user's login name.
The FTP Server, in.ftpd(1M), reads the ftpusers file. If the login name of the user matches one of the entries listed, it rejects the login
attempt.
The ftpusers file has the following default configuration entries:
root
daemon
bin
sys
adm
lp
uccp
nuucp
smmsp
listen
nobody
noaccess
nobody4
These entries match the default instantiated entries from passwd(4). The list of default entries typically contains the superuser root and
other administrative and system application identities.
The root entry is included in the ftpusers file as a security measure since the default policy is to disallow remote logins for this iden-
tity. This policy is also set in the default value of the CONSOLE entry in the /etc/default/login file. See login(1). If you allow root
login privileges by deleting the root entry in ftpusers, you should also modify the security policy in /etc/default/login to reflect the
site security policy for remote login access by root.
Other default entries are administrative identities that are typically assumed by system applications but never used for local or remote
login, for example sys and nobody. Since these entries do not have a valid password field instantiated in shadow(4), no login can be per-
formed.
If a site adds similar administrative or system application identities in passwd(4) and shadow(4), for example, majordomo, the site should
consider including them in the ftpusers file for a consistent security policy.
Lines that begin with # are treated as comment lines and are ignored.
