10 | 1) Introduction | |
11 | ||
12 | X3 supports a unique protection mechanism based on the military "Defense | |
13 | Readiness Condition" (DefCon) system. It is based on 5 levels of defense | |
14 | readiness defined as: | |
15 | ||
16 | DEFCON5 Normal peacetime readiness | |
17 | DEFCON4 Increased intelligence and security readiness | |
18 | DEFCON3 Increase in force readiness | |
19 | DEFCON2 Further increase in force readiness | |
20 | DEFCON1 Maximum force readiness. | |
21 | ||
22 | These are configurable levels that mandates what actions X3 should | |
23 | take in case of emergency and change in readiness status. | |
24 | ||
25 | It is used to prevent abuse to both Services, and the ircd on which they | |
26 | are running. Also to protect the users, primarily in the event of Clones | |
27 | and/or FloodBOT attacks. | |
28 | ||
29 | 2) Installation | |
30 | ||
31 | The DefCon system is part of O3, | |
32 | ||
33 | The DefCon system has to be configured on your x3.conf file to | |
34 | be enabled. | |
35 | ||
36 | Make sure you restart X3 after changing the DefCon configuration | |
37 | directives. | |
38 | ||
39 | 3) Configuration | |
40 | ||
41 | Pre-defined DefCon actions: | |
42 | ||
43 | No new channel registrations 1 | |
44 | No New Nick Registrations 2 | |
45 | No channel Mode changes 4 | |
46 | Force Chan Mode 8 | |
47 | Use Reduced Session Limit 16 | |
48 | KILL any new clients trying to connect 32 | |
49 | Services will ignore everyone but opers 64 | |
50 | Services will silently ignore everyone but opers 128 | |
51 | GLINE all new clients trying to connect 256 | |
52 | No new memos sent to block MemoServ attacks 512 | |
53 | SHUN all new clients trying to connect 1024 | |
54 | ||
55 | These are the values used to determine each defcon setting, are set via: | |
56 | ||
57 | "DefCon1 "XX"; | |
58 | "DefCon2 "XX"; | |
59 | "DefCon3 "XX"; | |
60 | "DefCon4 "XX"; | |
61 | ||
62 | To set the desired value, you simply add the value of the numbers together | |
63 | and place that as your DefCon# setting. For instance: | |
64 | ||
65 | Say you wish to set: | |
66 | ||
67 | No Channel Registrations, No Nickname Registrations and Services Ignoring | |
68 | everyone except for Operators. You would do this by: | |
69 | ||
70 | 1 + 2 + 128 (Each value listed above is added together) | |
71 | Giving: 131 | |
72 | ||
73 | You would then place this as which ever Defcon setting you want: | |
74 | ||
75 | "DefCon1" "131"; | |
76 | ||
77 | The recommended default values are safe to use on any network. | |
78 | ||
79 | 4) Usage | |
80 | ||
81 | X3 starts up in DEFCON5 (normal readiness) by default, this is configurable. | |
82 | To change the Defcon level in action use: | |
83 | ||
84 | /msg O3 DEFCON 1|2|3|4|5 | |
85 | ||
86 | 5) Usage Example | |
87 | ||
88 | Place the network on DEFCON3: | |
89 | ||
