This page describes the "Hosts" Access Type for an Xdm session. The
ViewStation has this feature to give you additional control of your Xdm
access.
XDMCP Hosts File Access
The XDMCP "Hosts"
Access Method is available with HDSware 3.1 and later versions.
The "Hosts" access method allows you to specify multiple hosts
with individual access methods for your XDMCP request. You can set up
an Xdm Hosts file by selecting the Hosts access method in Setup Mode and
entering the path to your Xdm hosts file in the "Hosts File" line.
A sample file is given below:
The Xdm hosts file contains a list of hosts, one per line. Each
host entry can be one of three XDMCP query types - Direct, Indirect, or
Broadcast. Host names starting with an asterisk (`*') are queried via
Indirect requests. Host names not starting with an asterisk are queried
via Direct requests. A host name of `BROADCAST' specifies to perform a
broadcast request. Each host entry also has an associated retry
timeout. The timeout parameter specifies how many seconds to send
requests to a host before trying the next host in the list. The default
timeout is 0 seconds. Hosts are tried in the order in which they appear
in the hosts file. Characters after a `#' character are comments.
This is a sample XDMCP hosts file:
# XDMCP hosts example file
#
*hdssun1 #
Indirect request to hdssun1, timeout=0
hds486 timeout=10 # Direct
request to hds486
hdshp timeout=15 # Direct request to hdshp
BROADCAST
# Broadcast request
This file specifies that at start_time + 0 seconds, an
indirect request is sent to hdssun1 and a direct request is sent to
hds486. At start_time + 10 seconds, a direct request is sent to hdshp in
addition to requests to hdssun1 and hds486. At start_time + 25 seconds,
a broadcast request will be sent in addition to requests to hdssun1,
hds486, and hdshp.
