[Xen-devel] Networking with MiniOS

[Lele Ma <lelema.zh@xxxxxxxxx>]

Dear All,

I am trying to enable networking with MiniOS.

I created a daytime server based on daytime.c shipped with MiniOS. The code in daytime.c is copied into stubdom/c/main.c and built with c-stubdom. 

Server thread is created successfully but client cannot establish tcp connection with server thread, neither from MiniOS itself or from anther VM (dom0).

The client code in MiniOS is:

-------------------------------

 while (1){

        targetconn = netconn_new(NETCONN_TCP);

            if ( targetconn == NULL ) {         

            /* No memory for new connection? */

            continue;

        }

        rc = netconn_bind(targetconn, &localip, 0);

        //... success binding

        rc = netconn_connect ( targetconn, &remote_ip, LISTEN_PORT ); 

        

        if ( rc != ERR_OK )

        {

            // always catched the error here

            printf("----%s: Error connecting. Now reconnect...\n", __FUNCTION__);

            netconn_delete ( targetconn );

            continue;

        }

    }

-------------------------------------------------

(Complete code: https://github.com/tinyvmi/tinynet/blob/master/daytime.c)

On dom0, I used telnet <minios-ip> <port> to connect, also with no luck.

Could anyone give some hints how should I build a tcp connection with MiniOS?  

Best,
Lele Ma
