rdma_xserver(1) RDMA CM communication server test program


rdma_xserver [-p port] [-c comm_type]


Uses the librdmacm to establish various forms of communication and exchange data.


-p port
Changes the port number that the server listens on. By default the server listens on port 7471.
-c communication type
Specifies the type of communication established with the client program. 'r' results in using a reliable-connected QP (the default). 'x' uses extended reliable-connected XRC QPs.


Basic usage is to start rdma_xserver, then connect to the server using the rdma_xclient 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.
