The inittab file is the master file in which the init program looks to execute its subsequent services. The very first services it executes are those located in the /etc/rc.d directory tree. The different run levels are defined as: 0 - Halt 1 - Single user mode 2 - Multi-user, without high level services 3 - Full multi-user mode 4 - Mostly unused 5 - X11 6 - Reboot On most Linux distributions, the run-level startup scripts are located in /etc/rc.d , e.g. Linux Server Security: Hack and Defend Linux Server Security: Hack and Defend.

IP aliasing is one of the most common ways of creating multiple IP addresses associated with a single NIC. Aliases have the name format parent-interface-name:X, where X is the sub-interface number of your choice. The process for creating an IP alias is very similar to the steps outlined for the real interface in the previous section, "Changing Your IP Address": Verify that no other IP aliases with the same name exists with the name you plan to use online. The kernel of UNIX is the hub of the operating system: it allocates time and memory to programs and handles the filestore and communications in response to system calls. As an illustration of the way that the shell and the kernel work together, suppose a user types rm myfile (which has the effect of removing the file myfile) ref.: Oracle Shell Scripting: Linux download epub download epub.
