1) Introduction

    Anope 1.6 onwards supports a unique protection mechanism based on the
    military "Defense Readiness Condition" (DefCon) system. It is based on 
    5 levels of defense readiness defined as:

    DEFCON5 Normal peacetime readiness
    DEFCON4 Increased intelligence and security readiness
    DEFCON3 Increase in force readiness
    DEFCON2 Further increase in force readiness
    DEFCON1 Maximum force readiness.

    These are configurable levels that mandates what actions Anope should
    take in case of emergency and change in readiness status.

    It is used to prevent abuse to both Services, and the ircd on which they 
    are running. Also to protect the users, primarily in the event of Clones
    and/or FloodBOT attacks. 

2) Installation

    The DefCon system is part of Anope's core,

    The DefCon system has to be configured on your services.conf file to
    be enabled. All directives are optional unless they depend on what
    options you enable for each level. Look for the "DefCon configuration"
    section on your services.conf file for more information.

    Make sure you restart Anope after changing the DefCon configuration
    directives.

3) Configuration

    Pre-defined DefCon actions:

    No new channel registrations                       1 
    No New Nick Registrations                          2 
    No MLOCK changes                                   4 
    Force Chan Mode                                    8 
    Use Reduced Session Limit                         16 
    KILL any new clients trying to connect            32 
    Services will ignore everyone but opers           64 
    Services will silently ignore everyone but opers 128 
    AKILL all new clients trying to connect          256 
    No new memos sent to block MemoServ attacks      512

    These are the values used to determine each defcon setting, are set via: 

    DefCon1 XX 
    DefCon2 XX 
    DefCon3 XX 
    DefCon4 XX 

    To set the desired value, you simply add the value of the numbers together 
    and place that as your DefCon# setting. For instance:

    Say you wish to set: 

    No Channel Registrations, No Nickname Registrations and Services Ignoring 
    everyone except for Operators. You would do this by: 

    1 + 2 + 128 (Each value listed above is added together) 
    Giving: 131 

    You would then place this as which ever Defcon setting you want: 
    
    DefCon1 131 

    The recommended default values are safe to use on any network.

4) Usage

    Anope starts up in DEFCON5 (normal readiness). To change the Defcon level 
    in action use: 
    
    /msg OperServ DEFCON 1|2|3|4|5 

5) Usage Example

    Place the network on DEFCON4:

    /msg OperServ DEFCON 4

    *** Global -- from OperServ: dengel Changed the DEFCON level to 4

    -OperServ- Services are now at DEFCON 4
    -OperServ- * No new channel registrations
    -OperServ- * No new nick registrations
    -OperServ- * No MLOCK changes
    -OperServ- * Use the reduced session limit of 5

    -Global- The Defcon Level is now at Level: 4

    Restore normal readiness:

    /msg OperServ DEFCON 5

    *** Global -- from OperServ: dengel Changed the DEFCON level to 5

    -OperServ- Services are now at DEFCON 5

    -Global- Services are now back to normal, sorry for any inconvenience
