| 37 | .Sh DESCRIPTION | |
| 38 | .Nm Spray | |
| 39 | sends multiple RPC packets to | |
| 40 | .Ar host | |
| 41 | and records how many of them were correctly received and how long it took. | |
| 42 | .Pp | |
| 43 | The options are as follows: | |
| 44 | .Bl -tag -width indent | |
| 45 | .It Fl c Ar count | |
| 46 | Send | |
| 47 | .Ar count | |
| 48 | packets. | |
| 49 | .It Fl d Ar delay | |
| 50 | Pause | |
| 51 | .Ar delay | |
| 52 | microseconds between sending each packet. | |
| 53 | .It Fl l Ar length | |
| 54 | Set the length of the packet that holds the RPC call message to | |
| 55 | .Ar length | |
| 56 | bytes. | |
| 57 | Not all values of | |
| 58 | .Ar length | |
| 59 | are possible because RPC data is encoded using XDR. | |
| 60 | .Nm Spray | |
| 61 | rounds up to the nearest possible value. | |
| 62 | .El | |
| 63 | .Pp | |
| 64 | .Nm Spray | |
| 65 | is intended for use in network testing, measurement, and management. | |
| 66 | This command | |
| 67 | .Bf -emphasis | |
| 68 | can be very hard on a network and should be used with caution. | |
