| /* The "real" RPC portmapper endpoints that I know of are: |
| * |
| * ncadg_ip_udp: 135 |
| * ncacn_ip_tcp: 135 |
| * ncacn_np: \\pipe\epmapper |
| * ncalrpc: epmapper |
| * ncacn_http: 593 |
| * |
| * If the user's machine ran a DCE RPC daemon, it would |
| * probably be possible to connect to it, but there are many |
| * reasons not to, like: |
| * - the user probably does *not* run one, and probably |
| * shouldn't be forced to run one just for local COM |
| * - very few Unix systems use DCE RPC... if they run a RPC |
| * daemon at all, it's usually Sun RPC |
| * - DCE RPC registrations are persistent and saved on disk, |
| * while MS-RPC registrations are documented as non-persistent |
| * and stored only in RAM, and auto-destroyed when the process |
| * dies (something DCE RPC can't do) |
| * |
| * Of course, if the user *did* want to run a DCE RPC daemon anyway, |
| * there would be interoperability advantages, like the possibility |
| * of running a fully functional DCOM server using Wine... |
