PC Launcher Installation
SunPCi Requirements
In order for PC launcher to work, SunPCi and its host workstation must be able to
ping each other by 'name'. To do this, you must have:
IP connectivity between the two.
Name services (whatever you happen to be using) set up on each so that you can
look up the other's name and get its IP address.
Because of the network architecture of SunPCi and the way it shares Ethernet access
with its host, the SunPCI and host cannot see each other on the network.
To work around this, use an IP routing system (a "real" router, another Sun system,
an NT system, etc.) on the same subnet to act as a proxy router.
Note – You must have account access to the IP router you have selected, since you
must add two routes to it.
For example, based on following setup:
SunPCi IP = 10.0.0.1
Host workstation IP = 10.0.0.2
Router IP = 10.0.0.3
you need to do the following:
1. On the host workstation:
route add 10.0.0.1 10.0.0.3 1
Note – You can add an /etc/rc script to make this happen at every reboot.
2. On the routing proxy:
route add 10.0.0.2 10.0.0.3 0
route add 10.0.0.1 10.0.0.3 0 (or the equivalent)
Caution – You must add routes to all three systems in this fashion in order for this
to work. Do NOT assume that "standard network default routers" or anything else
will provide similar functionality; they will not.
