NAME
HDS Chooser - XDMCP host menu
SYNOPSIS
Chooser is only available by setting run local chooser to yes in
the XDMCP options in Setup Mode when the xdmcp access mode is broadcast
or indirect.
DESCRIPTION
The HDS Chooser program presents a list of all hosts which are
willing to manage the session. The user may connect to any of the hosts
presented by selecting the host and pressing the Connect button. A host
may be selected via the mouse or by typing the desired selection into
the selection box. If a host is typed into the selection box which is
not listed, pressing the Connect button will result in a warning beep
and the connection will not be attempted.
The list will grow as any new hosts respond that they are
willing to manage. The chooser will send out the request with an
exponential backoff algorithm so that there will be no network traffic
when the chooser is up and the display is idle. The retransmissions
start at 2 seconds and back off by factors of 2 to 32 seconds and
discontinue after 126 seconds. The transmissions will restart after any
keyboard or mouse activity.
The user may also press the Refresh button to discard the
current list of willing hosts and begin collecting again. The refresh
button is most useful when returning to a display that has been idle
for some time. Since the list was compiled over time a host which in
the past was willing to manage may no longer be. While the user will be
informed of any new hosts that are willing to manage the moment the
mouse is touched, hosts which are no longer willing are never removed
from the list. By discarding the list and starting again with the
refresh button, the list will be made current.
If a host is chosen that is no longer willing or is no longer
on the network, the chooser will restart. There could be a 126 second
delay before the chooser is run if the host was removed from the
network.
Unlike the chooser provided with X11 Release 5 this chooser
can work both with X11R4 xdm and X11R5 xdm hosts since it does not work
via a forwarded request.
WIDGETS
In order to specify resources, it is useful to know the
hierarchy of the widgets which compose HDS Chooser. In the notation
below, indentation indicates hierarchical structure. The widget class
name is given first, followed by the widget instance name.
