Enable Logging of SSL Negotiation Errors

Description
Enable Logging of SSL Negotiation Errors
Resolution
Problem Definition:
By default, the Web access service does not log error messages when a client attempts to connect using an invalid SSL protocol, or if SSL negotiation fails. This article describes how to enable this additional logging through the use of a hand edit of a configuration file on the appliance.
Procedure:
Warning SonicWall strongly recommends that users not familiar or comfortable with the "vi" command or the command line contact SonicWall product support for assistance. Always back up your configuration before performing hand edits. Use the command line at your own risk. See KB item #2500 for some suggestions on enabling SSH access to the appliance and getting onto the command line.
- Using vi, edit /usr/local/app/mgmt-server/datastore/pending/sysconf/avconfig.xml.
- In this file, look for ewConf.
- Directly under ewConf will be a line that looks like this:
<logType>FFFFF7BF</logType> - Change FFFFF7BF to FFFFFFFF.
- Save the file and exit vi.
- Using KB #2612 as the starting point, change the ExtrawebHup line from current to pending in changestate.properties.
- Save the file and exit vi.
- Restart AMC by running this command:
/etc/init.d/mgmt-server restart - After AMC restarts, log back in and apply changes.
After making this change, the Web access service will begin logging SSL negotiation failures, as in the following example. This was from an Internet Explorer 7 client that was using SSLv2 when connecting to an appliance:
