|xrxHasFirewallProxy (class XrxHasFirewallProxy)|
|Specifies whether an X server firewall proxy (see xfwp) is running and should be used. Default is False. The X firewall proxy uses the X Security Extension and this extension will only allow clients to connect to the X server if host-based authentication is turned on. See xfwp(1) for more information.|
|xrxInternalWebServers (class XrxInternalWebServers)|
The web servers for which the X server firewall proxy should not be used
(only relevant when xrxHasFirewallProxy is True). Its value is a
comma separated list of mask/value pairs to be used to filter internal
web servers, based on their address. The mask part specifies which segments
of the address are to be considered and the value part specifies what the
result should match. For instance the following list:
matches the address sets: 198.112.45.* and 198.112.46.*. More precisely, the test is (address & mask) == value.
|xrxFastWebServers (class XrxFastWebServers)|
|The web servers for which LBX should not be used. The resource value is a list of address mask/value pairs, as previously described.|
|xrxTrustedWebServers (class XrxTrustedWebServers)|
|The web servers from which remote applications should be run as trusted clients. The default is to run remote applications as untrusted clients. The resource value is a list of address mask/value pairs, as previously described.|
If the RX document requests X-UI-LBX service and the default X server does not advertise the LBX extension, the RX Plug-in will look for the environment variable XREALDISPLAY to get a second address for your X server and look for the LBX extension there. When running your browser through lbxproxy you will need to set XREALDISPLAY to the actual address of your server if you wish remote applications to be able to use LBX across the Internet.
If the RX document requests XPRINT service, RX Plug-in looks for the variable XPRINTER to get the printer name and X Print server address to use. If the server address is not specified as part of XPRINTER, RX Plug-in uses the first one specified through the variable XPSERVERLIST when it is set. When it is not RX Plug-in then tries to use the video server as the print server. If the printer name is not specified via XPRINTER, RX Plug-in looks for it in the variables PDPRINTER, then LPDEST, and finally PRINTER,
Finally, if you are using a firewall proxy, RX Plug-in will look for PROXY_MANAGER to get the address of your proxy manager (see proxymngr). When not specified it will use ":6500" as the default.
When an authorization key is created for a remote application to use the X Print service, the RX Plug-in has to create the key with an infinite timeout since nobody knows when the application will actually connect to the X Print server. It then revokes the key when its instance is destroyed (that is when you go to another page). However, if the Plug-in does not get destroyed properly, which happens when the browser dies unexpectedly, the print authorization key will never get revoked.
