NAME

     rds-ping — test reachability of remote node over RDS

SYNOPSIS

     rds-ping [-c count] [-i interval] [-I local_addr] remote_addr

DESCRIPTION

     rds-ping is used to test whether a remote node is reachable over RDS.  Its interface is
     designed to operate pretty much the standard ping(8) utility, even though the way it works
     is pretty different.

     rds-ping opens several RDS sockets and sends packets to port 0 on the indicated host. This
     is a special port number to which no socket is bound; instead, the kernel processes incoming
     packets and responds to them.

OPTIONS

     The following options are available for use on the command line:

     -c count
             Causes rds-ping to exit after sending (and receiving) the specified number of
             packets.

     -I address
             By default, rds-ping will pick the local source address for the RDS socket based on
             routing information for the destination address (i.e. if packets to the given
             destination would be routed through interface ib0, then it will use the IP address
             of ib0 as source address).  Using the -I option, you can override this choice.

     -i timeout
             By default, rds-ping will wait for one second between sending packets. Use this
             option to specified a different interval. The timeout value is given in seconds, and
             can be a floating point number. Optionally, append msec or usec to specify a timeout
             in milliseconds or microseconds, respectively.
     Specifying a timeout considerably smaller than the packet round-trip time will produce
             unexpected results.
