???????????????? Why this is not successful ?????????
[EMAIL PROTECTED] sbin]# ./rtping 192.168.1.1
Real-time PING 192.168.1.1 56(84) bytes of data.

??????? 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 ????
