I have an old Sparc II machine running Aurora Sparc Linux 1.0 (RHL 7.3
equivalent). It comes with VNC 3.3.3. Older compiler and libraries
prevent building a VNC v4 variant.
I recently tried to setup this machine similarly to the newer Linux
machines running VNC 4.1.2-1. On these I use the "vnc.so" module with
Xorg in gdm.conf to attach to the console display and an "xinetd" script
to provide connections via XDMCP.
I know that the vnc.so module is not available in the 3.3 versions, but
I'd like to get the xinetd part running. After setting it up like the
other machines I get only "connection refused" errors or "main: end of
stream". I've checked that /etc/hosts.{deny,allow} are not preventing
connections and there's no firewall running on it. It should not need a
user auth file if it's going through XDMCP and "rbfauth" is disabled by
default, right?
if I try connecting with "vncviewer hostname" (no display) it always
says connection refused. I think it's trying to connect to the console
display.
If I try connecting with any of the other displays configured in
/etc/xinetd.d/vnc it doesn't give any errors, but doesn't open a VNC
session either. Here are sample messages on the terminal display when I
connect this way:

There's nothing in the system logs and I can't find a way to enable
logging on the connection.
