mkdir /home/ftp

b. Create the subdirectory /usr/bin under the ftp home directory, for

example:

cd /home/ftp

mkdir usr

cd usr

mkdir bin

Step 3. Copy the ls and pwd commands from /sbin and /usr/bin (respectively)

to ~ftp/usr/bin, and set the permissions on the commands to

executable only (mode 0111):

cp /sbin/ls /home/ftp/usr/bin

cp /usr/bin/pwd /home/ftp/usr/bin

chmod u=x,g=x,o=x /home/ftp/usr/bin/ls

chmod u=x,g=x,o=x /home/ftp/usr/bin/pwd

Step 4. Set the owner of the ~ftp/usr/bin and ~ftp/usr directories to root,

and set the permissions to not writable (mode 0555):

chown root /home/ftp/usr/bin

chmod u=rx,g=rx,o=rx /home/ftp/usr/bin

chown root /home/ftp/usr

chmod u=rx,g=rx,o=rx /home/ftp/usr

Step 5. Create the subdirectory etc under the ftp directory, for example:

cd /home/ftp

mkdir etc

Step 6. Copy /etc/passwd and /etc/group to ~ftp/etc.

These ﬁles are required by the ls command, to display the owners of ﬁles

and directories under ~ftp.

cp /etc/passwd /home/ftp/etc

cp /etc/group /home/ftp/etc

Step 7. In all entries in /home/ftp/etc/passwd, replace the password ﬁeld with

an asterisk (*), and delete the shell ﬁeld, for example:

ftp:*:500:1:anonymous ftp:/home/ftp:

tom:*:8996:20::/home/tom:
