Troubleshooting
Web Server Cannot Tell Whether Incoming Requests Originate Externally
or Internally
IP Spoofing is not enabled
Check the cluster’s configuration and enable the spoof option – this will cause the client’s IP
address to be used as the source address in packets sent to the server. Also ensure that
responses from the server go through Equalizer.
Why aren't my clusters working if the server status is "up"?
There are several reasons this could be happening. Make sure that Equalizer is being used as the
default gateway on all your servers, and that the server service or daemon is running. Sometimes
additional host or network routes will need to be added to the clustered servers in single network.
The
traceroute
(Unix) and
tracert
(Windows) commands are useful diagnostic tools. Trace
from the clustered server back to any client that is not able to resolve the cluster address. If
Equalizeris not showing up as the first hop, routing is the cause of the problem.

Log Contains SSL Errors with “wrong version number”
If you have one or more HTTPS clusters defined, you may see the following messages in the
Equalizer log:
ssl_err: 425:error:1408F10B: SSL routines:SSL3_GET_RECORD:wrong version number:s3_
pkt.c:360: ssl_err: fatal error with ip_address
These messages indicate that a client has sent an HTTPS request to an HTTPS cluster, but has
requested an SSL/TLS version that is not configured on the cluster. These messages are logged by
the SSL implementation used by Equalizer and do not necessarily indicate a problem on Equalizer.
For example, if you configure the HTTPS cluster to support SSLv3 ciphers only, then any time a
client requests a connection using an SSLv2 cipher, SSL will log these messages. Check the cipher
suite for the HTTPS cluster and the configuration of the client to ensure that the desired SSL
versions are being used.
