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.
