The scologin display manager can do more than run
the simple session that its default configuration provides.
In fact, scologin can control multiple servers,
both on the local machine and on remote machines, or X terminals.
There are two ways to specify the X servers that you want
managed by scologin:
If the server supports the X Consortium standard
X Display Manager Control Protocol, also known as
XDMCP, you can usually specify
the name or network address of
a remote machine running scologin at the
server.
XDMCP is a dynamic mechanism whereby
connections are made when requested by a display,
such as a workstation or an X terminal,
that can communicate through the protocol.
The SCO X server (Xsco) supports XDMCP.
If you want to configure scologin to run on
a set of console ttys (for example, on tty01
through tty12), or if you want scologin
to manage an X server that does not support XDMCP,
you can add an entry for each of the displays in
the /usr/lib/X11/scologin/Xservers
file. Each line in this file specifies a display that
should constantly be managed by scologin.
