Netra Proxy Cache Server Configuration Guide

Network Interface Configuration

The Netra Proxy Cache product supports network interface configuration by either of two means:

Establishing a serial connection from a terminal, another Sun machine, or a PC to the Netra Proxy Cache Server and using tip to connect to the server. Appendix A, Establishing a tip Connection," provides instructions for making this connection. This method of initial configuration is referred to as the TTY method and is described in "TTY Method".

Inserting a configuration diskette in another Sun machine, a Mac, or a PC and running a configuration program, then booting the Netra Proxy Cache Server with that diskette in the server's drive. The configuration diskette is shipped with the Netra Proxy Cache product. This method of network-interface configuration is referred to as the diskette method and is described in "Diskette Method".

Use the method, TTY or diskette, that is more convenient for you. Following initial host configuration, you will find a serial connection to the server to be very useful for troubleshooting.

See Table 1-2 for the information you need to complete either of the following procedures.

Note -

If you use DNS or NIS, it is useful to register the name and IP address of a Netra Proxy Cache Server in advance of network-interface configuration. By doing this, a Netra Proxy Cache machine is known throughout your network at the time you configure it.

TTY Method

Skip to "Diskette Method" for instructions for the diskette method.

In this section it is assumed that you have connected a terminal, workstation, or PC to your Netra Proxy Cache Server. See Appendix A, Establishing a tip Connection," for instructions.

To Use the TTY Method to Configure the Network Interface

Power on the Netra Proxy Cache Server.

At the Netra Proxy Cache Server, log in as user setup with the password setup.
```
NewNetra console login: setup
Password: setup password you enter is not displayed
```
Later, you have an opportunity to change the administration password.

Enter 1 to configure the local area network interface.

Welcome to the Netra server setup account

Select from the following options:
1) Configure the local area network interface.
2) Restore configuration from floppy.
3) Exit
Enter an option: 1

Press Return or enter 1 to accept the default choice for network interfaces:

This program configures the local area network interface.
Values shown in square brackets are the default values.
Hit <return> to accept these values.

The following interfaces are available:
1) SunFastEthernet 2.0 Port 0
2) SunFastEthernet 2.0 Port 1
Enter the number corresponding to the interface
to be configured [1]:

Enter the host IP address for the Netra Proxy Cache Server:
```
Enter the local area network host address for the
Netra server: 
```
Use dotted-decimal notation; for example, 129.144.118.2

Enter the netmask used on the network to which the Netra Proxy Cache Server is connected, or press Return to accept the default of 255.255.255.0:
```
Enter the local area network netmask for the
Netra server [255.255.255.0]:
```

Press Return or enter 1 to accept the values just entered, or enter 2 to repeat the steps just described:

The following configuration information has been entered:

Interface:      hme0
Host Address: <your IP address>
Netmask: <your netmask>

Select from the following options:
1) Configure hme0 with these values.
2) Discard these values and input new values.
3) Discard these values and exit.
Enter an option [1]:

After you accept the entered values, the following message is displayed:

SunFastEthernet 2.0 Port 0 has been configured for TCP/IP operation.
Host Address: <your IP address>
Netmask: <your netmask>

Welcome to the Netra server setup account


Select from the following options:
1) Configure the local area network interface.
2) Restore configuration from floppy.
3) Exit
Enter an option: 3

Make a note of the values displayed for host address and netmask.

Enter 3 (Exit).

The NewNetra console login is displayed:
```
NewNetra console login:
```
At this point, on a machine that is network-accessible to the Netra Proxy Cache Server, you can use a browser to connect to the Netra Proxy Cache machine.

To ensure network connectivity, on the machine on which you will run the browser for further configuration, enter:
```
non-netra% ping <netra host IP address>
```
If the host name and IP address of the Netra Proxy Cache machine is known to a name service, you can ping the host by name, instead of numeric address. If you receive a response indicating that the Netra Proxy Cache Server is reachable, proceed. If you cannot ping the Netra Proxy Cache machine, you must have entered the host IP address or netmask incorrectly. Check the values you noted in Step 8. If necessary, repeat the steps just described to configure your network interface.

On the machine on which you are running the browser, point the browser at:
```
http://<netra host IP address>:81
```
The string <netra host IP address> is the address you specified in the ping command, above.

Note -
Depending on the capabilities of your router, you might need to use a browser on a host on the same subnet as the Netra Proxy Cache Server.

At this point, proceed to "Using a Browser to Complete Initial Configuration".

Diskette Method

If you used the TTY method, as described in "TTY Method", skip to "Using a Browser to Complete Initial Configuration".

In this section it is assumed that you have the configuration diskette (labeled "Netra Proxy Cache Utilities Diskette") that is shipped with your Netra Proxy Cache Server.

To Use the Diskette Method to Configure the Network Interface

Make a copy of the Netra Proxy Cache Utilities diskette.

To make a copy on a Solaris machine, do the following:
1. Insert the utilities diskette in your diskette drive and enter the following sequence of commands:
```
% mkdir /tmp/hold This directory is an example
% volcheck
% cp /floppy/floppy0 /tmp/hold
```
2. Eject the utilities diskette.
3. Insert a blank, formatted diskette and enter the following sequence of commands:
```
% volcheck
% cp /tmp/hold /floppy/floppy0
```
4. Eject the copy of the utilities diskette.
  
  Note -
  The copying of your utilities diskette is critical. The diskette shipped with the product is read-only.

Insert the copy of the configuration diskette in the drive of another Unix machine (not the Netra Proxy Cache Server), a Mac, or a PC.

Invoke the config program on the diskette, as appropriate for your machine.

For example, on a PC that has a diskette drive A, invoke a:\config. For a Solaris machine, insert your diskette and enter the following sequence of commands:
```
% volcheck
% cd /floppy/floppy0
% ./config.ksh
```
When config comes up, it displays the following:
```
This program generates a configuration file
for the local area network interface.
Values shown in square brackets are the default values. 
```

Enter the host name of the Netra Proxy Cache Server:
```
Enter the Host Name for the Netra Server:
```

Enter the IP address of the Netra Proxy Cache Server:
```
Enter the local area network host address for the
Netra server: 
```
Use dotted-decimal notation. For example, 129.144.88.112.

Enter the netmask used on the network to which the Netra Proxy Cache Server is connected, or press Return to accept the default of 255.255.255.0:
```
Enter the local area network netmask for the
Netra server [255.255.255.0]:
```
The information you entered is saved on the diskette. This diskette now contains network-interface-configuration information for your Netra Proxy Cache Server.

Make a note of the values you entered for host name, host address, and netmask.

Eject the diskette from the drive.

Insert the same diskette in the diskette drive of your Netra Proxy Cache Server.

Power on the Netra Proxy Cache Server.

Wait (about a minute) till the Netra Proxy Cache Server completes the boot process. Then, on a machine that is network-accessible to the Netra Proxy Cache Server, you can use a browser to connect to the Netra Proxy Cache machine.

To ensure network connectivity, on the machine on which you will run the browser for further configuration, enter:
```
non-netra% ping <netra host IP address>
```
If the host name and IP address of the Netra Proxy Cache machine is known to a name service, you can ping the host by name, instead of numeric address. If you receive a response indicating that the Netra Proxy Cache Server is reachable, proceed. If you cannot ping the Netra Proxy Cache machine, you must have entered the host name, host address, or netmask incorrectly. Check the values you noted in Step 8. If necessary, repeat the steps just described to configure your network interface.

On the machine on which you are running the browser, point the browser at:
```
http://<netra host IP address>:81
```
The string <netra host IP address> is the address you specified in the ping command, above.

Note -
Depending on the capabilities of your router, you might need to use a browser on a host on the same subnet as the Netra Proxy Cache Server.

At this point, proceed to the next section.
