Corne, I'm afraid that you are mistaken.
Although the X11 specification allows for ports in the range 6000-6063, in practice the limit will normally be when X servers start to "collide" with other ports active on the system. Ports 10 and 11 are not "used by the X11 tunnel in SSH". X11 tunnelling support in SSH conventionally allocates ports starting at 10 and works its way up, one for each tunnelled X11 connection, so there could potentially be hundreds of SSH-forwarded X11 ports. These ports numbers are not reserved for use by SSH, which should cope with other processes allocating numbers from amongst them. In Gurjit's case, the VNC & X11 ports may clash, because he is launching Xvnc via xinetd in "wait" mode, so that Xvnc is started when a connection is first received on the specified port, and then stays active, using that port to accept new connections.
