Hi Friends ,
I am writing a program to detect if the IP address that we are assigning
to a machine / appliance is already assigned to a machine on the network.
I want to know if I can use the ARP protocol to send a REQUEST packet on
the ether net frame and test for the presence of the machine on the
network .
My problem is creating the ARP packet . I do not want to use libdnet or
libpcap but use the standard libc for that .
[ A catch in this ...
The IP stack is not up at this instance.
The only thing is that the network devices are initialized ...
The only this i can use is the LLC stuff.
]
Any pointer on this will most welcome ( especially code snippets and
sample code )
Regards
Abhijeet
