Installation - Recommended Post Installation Steps

Introduction

"Rainmail Server" works with Supplied Linux. The Supplied Linux can be installed on an ordinary IBM compatible PC. Post installation steps for installing "Rainmail Server" are given below.

2.8 Configuring your DSL, Cable Modem or Leased line

We will configure your "Rainmail Server" to work with these devices by establishing an (possibly virtual) interface to the DSL, Cable Modem or Leased line router. To do this, you will need to assign another IP address to your machine (this has to be on the same network segment as your router).

You will also need to know the IP address of the router. We will use the router as gateway. Finally, you will need to name this (possibly virtual) interface.

If you have only one network card, your new interface must be virtual. You can named the new interface based on the old interface. In this scenario, giving a name of "eth0:1" will do. If you have two network cards (one to your LAN and another top your router), you can give this interface a new name (like "eth1").

Once you have this information, start the configuration program using the steps given in "Starting the Configuration Program" and choose the "Select Connectivity" item on the left hand side. That will bring up the following screen:

In the above screen, select "Permanent" in the "Connectivity" field. This will enable the next four edit boxes. Enter IP address of router in the "Gateway Address" field, name of our new interface in "Gateway Device" field, our second IP address in "IP Address" field and the NetMask address in the " NetMask" field. Then press "Set" to use Cable Modem, DSL or Leased line connectivity to Internet. You will have to reboot the machine for this to take effect.

2. 9 Starting the Configuration Program

Once you have installed "Rainmail Server", you can start the configuration program in GUI mode.

• Start GUI mode. If you are not already in GUI mode, you can type in

  "startx"

  to get into the GUI mode.

• If your window manager is "KDE" or "GNOME", you can click on the start icon (in the bottom left of your screen), select "System Tools " , select "Other System Tools " and then "Configure Rainmail Server".

This will bring up the configuration program.

2.10 Testing Installation

• Testing Proxy Server

1. If the modem is currently connecting to an ISP, wait for it to disconnect (Do not turn off the modem).
2. Make sure that the modem is turned on and is plugged into the telephone line.
3. Open up Netscape browser.
4. Type in the URL http://www.getcloser.net/
5. If the modem starts to dial, it means that proxy server is working properly.
6. You can do other tests once you add users and modify configuration to suit your needs.
