rand rpc XID`s

[matador]

Hello.

I fast view the .../net/sunrpc/xprt.c (which grsec altered) and make conclusion that i must use generic interface..ok;
i write simple client & server programs (using clnt_create & registerrpc)
and run sniffer . what i see? just tcp or udp packets ..and where xid`s?

maybe its inside transport protocol packets or i must use raw protocol?

sorry for that, but i don`t really understand how exactly rpc protocol work.
so, can anybody help me, how can i check that xid`s become random?

thanks
