ETHER(3X) — Silicon Graphics

NAME

ether − monitor traffic on the Ethernet

SYNOPSIS

#include <rpcsvc/ether.h>

RPC INFO

program number:
ETHERPROG

xdr routines:
xdr_etherstat(xdrs, es)
XDR *xdrs;
struct etherstat *es;
xdr_etheraddrs(xdrs, ea)
XDR *xdrs;
struct etheraddrs *ea;
xdr_etherhtable(xdrs, hm)
XDR *xdrs;
struct etherhmem **hm;
xdr_etherhmem(xdrs, hm)
XDR *xdrs;
struct etherhmem **hm;
xdr_etherhbody(xdrs, hm)
XDR *xdrs;
struct etherhmem *hm;
xdr_addrmask(xdrs, am)
XDR *xdrs;
struct addrmask *am;

Xdr_etherhmem processes a single etherhmem structure. Xdr_etherhtable processes an array of HASHSIZE *struct etherhmems. The **etherhmem field of etheraddrs is actually a hashtable, that is, it is a pointer to an array of HASHSIZE hmem pointers.

procs:
ETHERPROC_GETDATA
no args, returns struct etherstat
ETHERPROC_ON
no args or results, puts server in promiscuous mode
ETHERPROC_OFF
no args or results, puts server in promiscuous mode
ETHERPROC_GETSRCDATA
no args, returns struct etheraddrs with information
about source of packets
ETHERPROC_GETDSTDATA
no args, returns struct etheraddrs with information
about destination of packets
ETHERPROC_SELECTSRC
takes struct mask as argument, no results
sets a mask for source
ETHERPROC_SELECTDST
takes struct mask as argument, no results
sets a mask for dst
ETHERPROC_SELECTPROTO
takes struct mask as argument, no results
sets a mask for proto
ETHERPROC_SELECTLNTH
takes struct mask as argument, no results
sets a mask for lnth
