Netra Proxy Cache Server Configuration Guide

Configuration Tables

This section contains tables that you can use when performing the tasks described in Chapter 2, Initial Host Configuration." It is recommended that you make a copy of these pages and fill out the tables before starting the procedures in Chapter 2, Initial Host Configuration.

Initial Host Configuration

Initial host configuration divides into the following sequence:

Network interface configuration
Completing initial host configuration (time zone, root password, and so on)

You can perform network interface configuration by either of two ways, the TTY method or the diskette method. These methods, as well as the entire initial host configuration process, are illustrated in Figure 1-1.

Figure 1-1 Initial Host Configuration

In terms of what you need to know, there is no difference between the TTY and diskette methods. In the diskette method, you enter the Netra Proxy Cache Server's host name during network interface configuration. In the TTY method, you specify a host name following network interface configuration.

Table 1-2 lists the data required for network interface configuration.

Table 1-1 Data Required for Network Interface Configuration


Parameter Name	Description	Enter Value Here:
network interface (TTY method only)	This is the network interface (`hme0`) with which your host name is associated. Example: `hme0`	`hme0`
host name of Netra Proxy Cache Server (diskette method only)	For convenience, this should be registered in your NIS and/or DNS maps. Example: `host1`
host IP address of Netra Proxy Cache Server	Use dotted decimal notation. Make a note of this address. You will use it when configuring the Netra Proxy Cache software. Example: 129.144.118.2
netmask	Netmask used in service network, in dotted decimal notation. Example: 255.255.255.0

After you perform network interface configuration, you point a browser at your Netra Proxy Cache Server and complete initial host configuration using the product's administration web pages. Table 1-2 lists the data required to complete initial host configuration.

Table 1-2 Data Required to Complete Initial Host Configuration


Parameter Name	Description	Enter Value Here:
time zone	Time zone in which host resides. Example: US/Pacific
locale	Locale in which host resides. Example: English (Only choice in the current release)
host name of Netra Proxy Cache Server (only if you performed TTY method for network interface configuration)	For convenience, this should be registered in your NIS and/or DNS maps. Example: `host1`
System administrator alias	Email addresses that will receive mail addressed to `root@<netra host name> or` `Postmaster@<netra host name>`.
root password	There is no default. That is, you start with no root password.
administration account name	The administration account name is `setup`.
administration password	The default password is `setup`. You need this password to access the Netra Proxy Cache administration web pages and the `setup` system account.
DNS domain name (if DNS is used)	Domain in which your Netra Proxy Cache host resides. Examples: `acme.com` or `sales.acme.com`
IP address of DNS server (if DNS is used)	Use dotted decimal notation. This is the DNS server that will resolve the name of the Netra Proxy Cache Server. Example: 129.144.91.24
NIS domain name (if NIS is used)	NIS domain in which your Netra Proxy Cache host resides. Examples: `acme.com` or `eng.acme.com`

Proxy Cache Service Configuration

Use the values you enter in Table 1-3 and Table 1-4 to configure the proxy cache service.

Table 1-3 Data for Basic Proxy Cache Configuration


Parameter Name	Description	Enter Value Here:
HTTP port	Port number used by the Netra Proxy Cache Server for receiving web requests. Most users can accept the default of 8080. Example: 8080
Inside firewall?	In a corporate setting, most proxy cache servers are inside a firewall.
Domains inside firewall	For domains not on this list, if the server cannot find a requested object in its local cache, it always tries to fetch the URL from a parent or sibling.



Parent proxies	If you are inside a firewall, you probably have a parent proxy. You can have multiple parents. See following table.

The Netra Proxy Cache Server supports multiple parent and sibling proxies. For each parent of your server, find out the following information:

The port it uses for HTTP

The port it uses for the Inter Cache Protocol (ICP)

Whether it supports tunneling of the Secure Sockets Layer (SSL) protocol

Whether it supports persistent connections (as supported by popular browsers such as Netscape Navigator. (Netscape and Netscape Navigator are trademarks of Netscape Communications Corporation.)

If your parent is a Netra Proxy Cache Server, keep in mind that the server uses default port numbers of 8080 and 3130, for HTTP and ICP, respectively. Also the Netra Proxy Cache Server supports SSL tunneling and persistent connections.

If your parent is not a Netra Proxy Cache Server, consult the documentation for that server to determine whether it supports ICP, SSL tunneling, and persistent connections.

Table 1-4 Parent Proxies (Enter Names and Values)


Parent Name	HTTP Port	ICP Port (Enter 0 if ICP not supported)	Support SSL tunneling? (y/n)	Support persistent connections (y/n)
