After a whole afternoon's reading and working, I did make the RTNet and
rtping work. But some problem and confusion still there,
Hope somebody can help me on this.
Please go through the following attached TXT file

Thanks again, Howard.

???????????????? Why this is not successful ?????????
[EMAIL PROTECTED] sbin]# ./rtping 192.168.1.1

??????? This is successful after I added the route for 192.168.1.1 ????
???????
Can anybody help to clarify and solve this for me.
now I do the following:
[EMAIL PROTECTED] sbin]# ./rtifconfig rtlo up 127.0.0.1
[EMAIL PROTECTED] sbin]# ./rtping 192.168.1.103
Real-time PING 192.168.1.103 56(84) bytes of data.
64 bytes from 127.0.0.1: icmp_seq=1 time=0.0 us
???? Why this rtping is coming back from 127.0.0.1 instead of 192.168.1.103 ???
1. Then I do ifconfig up rteth0, rteth0-mac and rtlo.
2. ping 192.168.1.103 and 192.168.1.1
3. ping failed - network is not reachable.
????? What is the problem with Linux regular ping ?????
????? Do I have to configure the route for linux interface etc ????
????? If the ping would work in linux space in above situation ????
Thanks a lot.
Regards,
Howard.
