Chapter 6: Administering Virtual Clusters
88 Equalizer Installation and Administration Guide
You do not need to configure Equalizer as the gateway for the servers if you have disabled the
IP spoof flag for the cluster.
• Server responses (and client requests) must contain 64 or fewer headers; any packet that
contains more than 64 headers is dropped by Equalizer (along with the connection), and a
message like the following is printed to Equalizer’s event log:
Warning: Dropping connection from ip-address -- too many headers
Make sure that your server software is configured to return 64 headers or less in any response
it sends back through Equalizer.
If your application must use 64 headers or more in server responses, then you can turn the
spoof flag off so that server responses go back to the client without going through Equalizer.
Be aware, however, that this has no effect on the client side; any packets from the client with
more than 64 headers will still be dropped by Equalizer (and a warning appended to the event
log). In most cases, client requests do not include that many headers.
Adding a Server to a Cluster
To add a server (see Figure 44) to a virtual cluster, follow these steps:
1. Log into the Equalizer Administration Interface in Edit mode.
2. In the left frame, click the name of the cluster to which you want to add the server. The
cluster’s parameters appear in the right frame.
3. Select menu > Add Server. The add server screen opens in the right frame. (The figure below
shows the screen with the advanced check box enabled.)
