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 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.
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 |
|
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.
