Troubleshooting "A connection failure has occurred", "The specified server could not be found" or si

When you attempt to connect to the Internet, you may see alert messages such as: "The server could not be found." "The specified server could not be found." "A connection failure has occurred." "Connection attempt failed." "Name servers not responding." Despite the alert, some Internet (TCP/IP) applications may function normally. Tip: In Mac OS X v10.4 or later, you can click the "Assist me" button in the Network preference pane, then follow the onscreen prompts for network diagnostics. However, the following information is good for any version of Mac OS X.

rdma_client

RDMA_CLIENT(1)							     librdmacm							    RDMA_CLIENT(1)

NAME

       rdma_client - simple RDMA CM connection and ping-pong test.

SYNOPSIS

       rdma_client [-s server_address] [-p server_port]

DESCRIPTION

       Uses  synchronous librdmam calls to establish an RDMA connection between two nodes.  This example is intended to provide a very simple cod-
       ing example of how to use RDMA.

OPTIONS

       -s server_address
	      Specifies the address of the system that the rdma_server is running on.  By default, the client  will  attempt  to  connect  to  the
	      server using 127.0.0.1.

       -p server_port
	      Specifies the port number that the server listens on.  By default the server listens on port 7471.

NOTES

       Basic usage is to start rdma_server, then connect to the server using the rdma_client program.

       Because	this  test maps RDMA resources to userspace, users must ensure that they have available system resources and permissions.  See the
       libibverbs README file for additional details.
