There is nothing to learn, given the circumstances. There are certain system administration privileges and they are given to certain persons - all that for a reason! If you do not have these privileges you either need to get them (temporarily or permanent) or you should not get them.

In other words: get root privileges and you are able to exercise them or don't get root privileges and subsequently don't exercise them. It would only mean that the system is poorly set up if you could do something which should only be available to root without actually being root.

UNIX systems (and Linux systems in this respect are UNIX systems too) are very secure designwise. It is possible to set up a UNIX system with poor security, but all the means to get a very secure system are there and can be used if the owner of a system wants that. Even the default setup of systems is - designwise - secure. What you wanted would be a severe breach of security. It is possible to get that but only if the system is very poorly set up and some default security means are purposefully worked over to allow for that mode of operation.

I hope this helps.

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.
