Re: sending a packet using raw socket

thank u guys...
thank u soo much for the info.

Now i am confirmed tat I can build my own structure and hand it to IP
layer using raw sockets.
now i am trying to write various structures and convert it to strings
for sendto..

My question is..
for handling ICMP packets, the structure is defined in ip_icmp.h, but
for OSPF no header file is defined.
so we need to define our own structure and fill in the header..
so , are we allowed to build any structure with any members on it?
how does the IP layer know if the structure is valid?
is there any specific headers(OSPF) which has to be mandatorily
filled?

please do reply..
i am ignorant..
