Testing Your Basic Configuration

Once you have installed and configured Equalizer and your servers, perform tests to verify that Equalizer is

working properly.

To perform these tests, you need the following:

l A test machine on the internal network (the same physical network as the servers; one of the server

machines can be used for this purpose).

l If you have a two-network configuration, a test machine on the external network.

l A client machine somewhere on the Internet, to simulate a “real-world” client. This machine should be set

up so that the only way it can communicate with your servers or Equalizer is through your Internet router.

Then follow these steps:

1. PingEqualizer’s external address (if configured) from a host on the external network interface address.

2. Ping Equalizer’s internal address from a host on the internal network interface address.

If DNS is configured, ping a host on the Internet (e.g., www.coyotepoint.com) from Equalizerto ensure that

DNS and the network gateway are functioning properly.

4. From the internal-network test machine, ping the physical IP address of each server. You should be able to

successfully ping all of the servers from the test machine.

5. From the internal-network test machine, ping the server aliases on each of the servers. You should be able

to successfully ping all of the servers from the test machine using their aliases.

6. From the internal test machine and each of the servers, ping the Equalizer address that you use as the

default gateway on your servers. (If you use a two-network topology, this will be Equalizer’s internal

address or failover alias.)

7. From the internal-network test machine, connect to the server aliases on service ports of running daemons

(you may need to configure telnet or ssh services on Windows servers). You should be able to connect

successfully to the server aliases.

8. If you use a two-network configuration: From the external-network test machine, ping a physical server IP

address using ping -R to trace the route of the ping. The EqualizerIP address should appear in the list of

interfaces that the ping packet traverses. You can also use the traceroute (UNIX) or tracert (Windows)

tools to perform this test.

9. Log into the GUI on either the external (if configured) or internal interfaces, as described in "Logging In" on

page 192.
