SSL Client Protocols

Which SSL protocols to allow for client HTTPS/SSL connections when walking or performing results authorization, i.e. for connections from the Search Appliance to remote https:// URLs. The default is to leave SSLv2 and SSLv3 disabled, as these are known to be vulnerable to attacks.

Sometimes a crawler's connection fails at (or soon after) the SSL negotiation, possibly with the error message "Missing HTTP response line in reply from ...". This may be due to settings on the remote server that disallow certain SSL protocols - yet those protocols were enabled under SSL Client Protocols (e.g. for legacy reasons). In such cases, disabling various SSL protocols may enable the connection to succeed.

Note: To change the server-side SSL protocols accepted by the Search Appliance - e.g. for admin, search, Dataload etc. - see HTTPS/SSL Protocols under System Wide Settings.
