Exercise 71: Montana Expeditions

Three actions need to take place to meet the needs of this customer. The first is to change the default permissions on all newly created files to 664. Subtracting that from 666 leaves a value of 002.

To change the permissions on all files currently in the /tmp directory to 751, the easiest solution is to open a terminal session, change to the /tmp directory, and use the command chmod 751 *.

Last, to move the passwords from the /etc/shadow file to the /etc/passwd file, within the terminal session, use the command pwunconv (the opposite of which is pwconv).
