tc_init
tc_init determines the node ID, ethernet address, and IP address for
all nodes in the complex. This information is then stored in the NVRAM
of all nodes as one 12-byte entry per node. Each 12-byte entry has the
format shown in Figure 54:

In addition, tc_init updates the ARP entries on the teststation by
executing as root. If it can not execute as root, then the following error is
displayed:
** This utility must be executed as root.
** Please login as root and try again.
tc_init outputs node information shown in the following example.
