Otherwise, local address and destination address should be on the same
interface (under RTnet, rtlo only listens to the IP assigned to it
explicitly).
But still the problem exit. I used 192.168.0.10 as a server and 127.0.0.1 as a
client. I executed like,
./rttcp-server -l 192.168.0.10 (its waiting for the client)
./rttcp-client (I am using rtlo here)
Now I am getting the error, Connect to server : Network is unreachable
Even I changed destination and local IP. But getting the same error.
FYI, I tried the steps mentioned in README.Special notes. I can able to ping
the other machine address. However I could not able to ping the local rteth0
address. ie, ./rtping 192.168.0.10 provides 100% packet loss. I guess this is
the main reason for network is not reachable in the above program.
Even I tried the same READE.special notes for local rteth0 also. But I could
not able to ping this IP. Why?.
My route talbe is:
0A 192.168.0.10 rteth0
0B 192.168.0.11 rteth0
I can able to ping the another machine from rtifconfig. But ping is failed for
local IP, ie 192.168.0.10.

Thanks for the info. Yes, I did not enabled RT-TCP.
Now I enabled RTTCP. recompiled the rtnet source. Then inserted the rttcp.ko
modules. Now I did not get the error,
ioctl (RTNET_RTIOC_EXTPOOL):Invalid argument
