macOS compatiblity

[advaleigh]

I am attempting to get a NFS server working on macOS Sierra (10.12.6). java version "1.8.0_151". The same code works fine on CentOS 7.

In the macOS case, it successfully registers (visible in rpcinfo) and the bindings look correct. The system has the firewall disabled.

showmount -e fails with "showmount: Cannot retrieve info from host: localhost: RPC failed:: RPC: Procedure unavailable"

~aleigh$ rpcinfo -u localhost nfs
rpcinfo: RPC: Procedure unavailable
program 100003 version 0 is not available
rpcinfo: RPC: Procedure unavailable
program 100003 version 4294967295 is not available

~ aleigh$ rpcinfo -u localhost mountd
rpcinfo: RPC: Procedure unavailable
program 100005 version 0 is not available
rpcinfo: RPC: Procedure unavailable
program 100005 version 4294967295 is not available

I am willing to put in the time to fix this problem, but I wonder if this is a known issue, or if there is any advice.

public class NfsServer {
private static final MechaLogger logger = MechaLoggerFactory.getLogger(NfsServer.class);
private final OncRpcSvc service;

public NfsServer(VirtualFileSystem vfs, ExportFile exportFile) throws IOException {
    // create the RPC service which will handle NFS requests
    service = new OncRpcSvcBuilder()
            .withPort(2049)
            .withTCP()
            .withUDP()
            .withAutoPublish()
            .withWorkerThreadIoStrategy()
            .build();

    // create NFS v4.1 server
    //   NFSServerV41 nfs4 = new NFSServerV41(new MDSOperationFactory(), null, vfs, exportFile);

    // create NFS v3 and mountd servers
    NfsServerV3 nfs3 = new NfsServerV3(exportFile, vfs);
    MountServer mountd = new MountServer(exportFile, vfs);

    // register NFS servers at portmap service
    //  service.register(new OncRpcProgram(100003, 4), nfs4);
    service.register(new OncRpcProgram(100003, 3), nfs3);
    service.register(new OncRpcProgram(100005, 3), mountd);
}

public void run() {
    try {
        service.start();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

public static void main(String args[]) throws IOException {
    NfsServer srv = new NfsServer(new SdsFs(), new ExportFile(new File("exports.nfs")));
    srv.run();
    ThreadUtil.forever();
}

}

Actually I expect that your simple example must work ander osx. Let me test and come back to you. Wat do you see when you run rpcinfo localhost?
