I have installed RTnet on my two PCs, which is having xenomai as OS. Since my
NIC was not supported by RTnet, i have purchased a realtek 8139 NIC and
inserted
in to my PCI slot.
My configuration file rtnet.conf is as follows:
================================================================================
Master side :
================================================================================
# This file is usually located in <PREFIX>/etc/rtnet.conf
# Please adapt it to your system.
# This configuration file is used with the rtnet script.
# RTnet installation path
prefix="/usr/local/rtnet"

I got the following messgae on master and slave side
--------------------------------------------------------------------------------
================================================================================
Master side

Stage 1: searching for master...
On both sides (Master as well as Slave) no further progress is happening..
pressed Cntr+C And rtping to other system is also not working (In this case
./rtping 10.0.0.3). It gives the message as shown below:
Real-time PING 10.0.0.3 56(84) bytes of data.
RTnet: host 10.0.0.3 unreachable
ioctl: No route to host
Pl help me?
Thanks in Advance ...
