Sun Remote System Control (RSC) User's Guide

ppp_local_ip_addr

Use this variable to specify the Internet protocol (IP) address for RSC to use during a PPP session; use standard dot notation. If this variable is empty, RSC expects the remote node to set the Internet address dynamically. The default setting is 0.0.0.0 (empty). Changes to this variable take effect on the next PPP connection over the RSC serial port.
