# rds-ping(1)

test reachability of remote node over RDS

## 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)](/ping/8.md) 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.
