Hi all, I am working with stateful packet filters and I'd like to know about RPC sessions. RPC normal communication sequence is: Client -----------------> POrtmapper Portmapper -----------> Client Client ----------------> Server Server----------------> Client All right ! Yes, but at one second client 's query: Client look for portmapper server binding in its cache and (Do it look for binding?) client ------------> server server-----------> client . : Cache expires client-------------> Portmapper portmapper---> Client Client-----------> server Server-------> client Is it ok?????? What is timeout of these bindings in client's cache for NFS clients, in this last case (if true, of course)? Regards, Marcelo (marcelo.lima () dcc unicamp br)
