Because iptables requires elevated privileges to operate, it must be executed by user root, otherwise it fails to function. On most Linux systems, iptables is installed as /usr/sbin/iptables and documented in its man page, which can be opened using "man iptables" when installed. iptables is also commonly used to inclusively refer to the kernel-level component Xtables that does the actual table traversal and provides an API for kernel-level extensions.
