- _s_p_r_a_y sends a one-way stream of packets to _h_o_s_t using RPC, and then
- reports how many were received by _h_o_s_t and what the transfer rate was.
- The hostname can be either a name or an Internet address.
-
- OOOOPPPPTTTTIIIIOOOONNNNSSSS
- ----cccc _c_o_u_n_t Specifies how many packets to send. The default value of
- _c_o_u_n_t is the numbers of packets required to make the total
- stream size 100000 bytes.
-
- ----dddd _d_e_l_a_y Specifies how may microseconds to pause between sending each
- packet. The default is 0.
-
- ----iiii Use ICMP echo packets rather than RPC. Since ICMP
- automatically echos, this creates a two way stream.
-
- ----llll _l_e_n_g_t_h The _l_e_n_g_t_h parameter is the numbers of bytes in the ethernet
- packet that holds the RPC call message. Since the data is
- encoded using XDR, and XDR only deals with 32 bit quantities,
- not all values of _l_e_n_g_t_h are possible, and _s_p_r_a_y rounds up to
- the nearest possible value. When _l_e_n_g_t_h is greater than
- 1514, then the RPC call can no longer be encapsulated in one
- Ethernet packet, so the _l_e_n_g_t_h field no longer has a simple
- correspondence to Ethernet packet size. The default value of
- _l_e_n_g_t_h is 86 bytes (the size of the RPC and UDP headers)
