11 rds-ping is used to test whether a remote node is reachable over RDS.
12 Its interface is designed to operate pretty much the standard ping(8)
13 utility, even though the way it works is pretty different.
14 rds-ping opens several RDS sockets and sends packets to port 0 on the
16 indicated host. This is a special port number to which no socket is
17 bound; instead, the kernel processes incoming packets and responds to
18 them.
19
21 The following options are available for use on the command line:
22 -c count
24 Causes rds-ping to exit after sending (and receiving) the speci‐
25 fied number of packets.
26 -I address
28 By default, rds-ping will pick the local source address for the
29 RDS socket based on routing information for the destination
30 address (i.e. if packets to the given destination would be routed
31 through interface ib0, then it will use the IP address of ib0 as
32 source address). Using the -I option, you can override this
33 choice.
34 -i timeout
36 By default, rds-ping will wait for one second between sending
37 packets. Use this option to specified a different interval. The
38 timeout value is given in seconds, and can be a floating point
39 number. Optionally, append msec or usec to specify a timeout in
40 milliseconds or microseconds, respectively.
41 Specifying a timeout considerably smaller than the packet round-trip time
42 will produce unexpected results.
