Name

linxdisc.conf - custom settings for linxdisc

Synopsis

/etc/linxdisc.conf

Description

This file contains configuration variables for the linxdisc daemon. For non-configured variables, default values are used.

The linxdisc.conf must be located in the /etc directory, unless specified when linxdisc is started.

The variables are set using this semantics: VALUE="value1 value2 ..."

When the linxdisc daemon catches a SIGHUP, the configuration will be reread. IFACE, LINX_NETWORK_NAME and NODE_NAME will not be changed during runtime, while ALLOW and DENY will be applied immediately to close disallowed connections and when creating new connections.

Variables

IFACE
specifies what network interface(s) to use. Only real devices are supported. Several interfaces can be specified. e.g. IFACE="eth0 eth1". Default is to use all available devices.

LINX_NETWORK_NAME
specifies the name of a LINX cluster. linxdisc only creates LINX communication links to nodes, advertising the same cluster name. All nodes must have the linxdisc daemon running. Default is the cluster name "undefined".

NODE_NAME
specifies a node name to advertise. It is used by other nodes to filter against the allow/deny filter chains. It is also used as the recommended local link name, when linxdisc in a remote node creates LINX communication links to this node, as a response to the advertisement. Default node name is the hostname. Example: NODE_NAME="server1".

ALLOW
chain. If specified, linxdisc will only accept connections to nodes with the specified advertised node names. Names are given in a string, separated by spaces. This variable can be set several times in the configuration file and the names will be concatenated to one ALLOW chain. Example: ALLOW="node1 node2".

DENY
chain. NOTE: This setting will not have any effect if ALLOW is set. If DENY is specified instead of ALLOW, linxdisc will allow LINX connections to any node, except those with advertised node names listed here. Names are given in a string, separated by spaces. This variable can be set several times in the configuration file and the names will be concatenated to one DENY chain.

PARAM
List of parameters to apply to all links created by linxdisc. For a description of parameters and allowed values, see linxcfg(1) . This variable can be set several times in this file and the specified parameters are concatenated to one PARAM chain.
