(For the technical reader, I was able to create a .rhosts file in the bin account configured to allow me to log in without having to provide a password. A .rhosts file is a configuration file used with certain legacy system programs known as the "R-services," which are used for logging in or executing commands on a remote computer. For example, a .rhosts file can be configured to allow the user "kevin" from the hostname "condor" to log in without providing a password. In the example above, two plus signs separated by a space provides a wildcard for both the user and the hostname of the computer—meaning that any user can log in to the account or execute commands. Because the bin account had write access to the "/etc" directory, I was able to replace the password file with my own modified version that allowed me to gain root access.)
