Homework and Emergencies Homework & Coursework Questions Trouble with setting permissions and such Post 303045239 by vbe on Saturday 14th of March 2020 08:23:33 AM

now I am stuck with making the passwords be 16 characters long and ensuring that admin has general sudo access.
Once solved the above remark I made
You can start dealing with this 2 tasks, the first we can't really help we don't know your platform, very likely linux but I am no linux specialist, all I can say is to look at you course again for clues, as what is asked will not be found in /etc/passwd or shadow file... You should have something dealing with PAM e.g. in Debian and debian based, password policies are defined in /etc/pam.d/common-password file

ensuring that admin has general sudo access
is sudo related, and so what you need to check/add/modify in the sudoers file using visudo, very important to use that and no other editor as it will check that there is no syntax error which would corrupt the sudoers file, I understand admin should have same as root...

       ln - link to a file

       ln [ -f ] [ -i ] [ -s ] name1 [name2]
       ln [ -f ] [ -i ] [ -s ] name ... directory

       A  link is a directory entry referring to a file.  A file, together with its size and all its protection information may have several links
       to it.  There are two kinds of links: hard links and symbolic links.

       By default makes hard links.  A hard link to a file is indistinguishable from the original directory entry.  Any  changes  to  a  file  are
       effective independent of the name used to reference the file.  Hard links may not span file systems and may not refer to directories.

       Given  one or two arguments, creates a link to an existing file name1.  If name2 is given, the link has that name.  The name2 may also be a
       directory in which to place the link.  Otherwise it is placed in the current directory.	If only the directory is specified,  the  link	is
       made to the last component of name1.

       Given  more  than two arguments, makes links to all the named files in the named directory.  The links made have the same name as the files
       being linked to.

       -f   Forces existing destination pathnames to be removed before linking without prompting for confirmation.

       -i   Write a prompt to standard output requesting information for each link that would overwrite an existing file.  If  the  response  from
	    standard input is affirmative, and if permissions allow, the link is done. The -i option has this effect even if the standard input is
	    not a terminal.

       -s   Creates a symbolic link.

	    A symbolic link contains the name of the file to which it is linked.  The referenced file is used when an operation  is  performed	on
	    the  link.	 A  on a symbolic link returns the linked-to file.  An must be done to obtain information about the link.  The call may be
	    used to read the contents of a symbolic link.  Symbolic links may span file systems and may refer to directories.
