Oracle iPlanet Web Proxy Server 4.0.14 Configuration File Reference

add_parent

The add_parent function identifies and configures a parent server in an ICP neighborhood.

Syntax

add_parent name=name icp_port=port number proxy_port=port number 
	mcast_address=IP address ttl=number round=1|2

Note –

The above text should be on one line in the icp.conf file.


Parameters

name specifies the name of the parent server. This value can be a DNS name or an IP address.

icp_port specifies the port on which the parent listens for ICP messages.

proxy_port specifies the port for the proxy on the parent.

mcast_address specifies the multicast address the parent listens to. A multicast address is an IP address to which multiple servers can listen. Using a multicast address enables a proxy to send one query to the network that all neighbors listening to that multicast address can receive. This process eliminates the need to send a query to each neighbor separately.

ttl specifies the time to live for a message sent to the multicast address. ttl controls the number of subnets a multicast message will be forwarded to. If the ttl is set to 1, the multicast message will only be forwarded to the local subnet. If the ttl is set to 2, the message will go to all subnets that are one hop away.

round specifies in which polling ro-und the parent will be queried. A polling round is an ICP query cycle. Possible values are:

Example

add_parent name=proxy1 icp_port=5151 proxy_port=3333 
	mcast_address=189.98.3.33 ttl=3 round=2
