About XDMCP X server options

Any X server that supports the XDMCP protocol can request a scologin session. To do this, the server must be started with the appropriate options to request the session.

The SCO X server (Xsco) uses the following options to determine how it uses XDMCP:

-broadcast

enables XDMCP and broadcasts BroadcastQuery packets to the network. The first responding display manager is chosen for the session.

-class display_class

sets the value of the additional XDMCP display qualifier, which is used in resource lookup for display-specific options. By default, the value is ``MIT-Unspecified''.

-cookie xdm-auth-bits

sets the value of a private key shared between the X server and the manager, which is used when testing XDM-AUTHENTICATION-1

-displayID display-id

allows the display manager to identify each display so that it can locate the shared key

-indirect host_name

enables XDMCP and sends IndirectQuery packets to the specified host

-once

exits the X server after the first session is over. Normally, the X server keeps starting sessions, one after the other.

-port port_num

specifies an alternate port number for XDMCP packets. It must be specified before any -query, -broadcast or -indirect options.

-query host-name

enables XDMCP and sends Query packets to the specified host
