Bad for me :-)
But thanks for the response !

If you talk about the sockaddr_dn structure, i think it's correctly configu=
red=20
(it's a named object) :

    sockaddr.sdn_family =3D AF_DECnet;
    sockaddr.sdn_flags  =3D 0x00;
    sockaddr.sdn_objnum  =3D 0x00; /* for a named object ? */
    sockaddr.sdn_objname  =3D "TASK";
    sockaddr.sdn_objnamel  =3D 4;
    memcpy(sockaddr.sdn_add.a_addr, np->n_addr,2);
    ...

etc ....

Even if we configure the accessdata_dn structure, it doesn't works (hope it=
's=20
optional ...).

=46or the moment, we are going to compile a single/simple server with all t=
he=20
API used in the real one : TASK_QIOW (which called itself QIO). ADA is a ve=
ry=20
strange langage (for our point of view) and we need to understand much more=
=20
how it works. But we hope there are no uncompatibility between both (ADA=20
decnet layer and Linux layer) ...

You have trying to change some parameters (with setsockopt), but without=20
success. We need to continue :-)
