RDS-PING(1)
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.
