hmm, this is kinda nice, maybe a way with defcon 1 it kicks them a configurable amount of times, then bans them? just an idea

 

title is missing version

 

Done.

 

Interesting, but MCBans just for trying to join? This is why I refuse to use MCBans...

 

You can Configure to use McBans. In the Configuration, McBans is set to false.

 

Interesting idea!

Can you add to defcon level 2 to make them temporary mcbans? That makes more sense to me, and perhaps configurable time.

Then the kick message could say like "Temporarily banned for 5 minutes, server is in Defcon 2" or so.

===

Also, perhaps DC 1 and/or 2 could be configured to disable building/breaking in all worlds?

And what about an option to kick all players when moving to DefCon 2? Or possibly make that DefCon 3

Ok some issues:

Loaded plugin for the first time, no MCDefcon folder is created, so I have no idea where or what the config file is.

Also, writing "dc" or "defcon" on console errors:

Code:

>dc

Alright i'll check that out. Also i'll change Defcon 2 to Temp Bans and add Defcon 3 for Regular Bans with the McBans Type. And for know, /dc and /defcon won't work in console, i'll add that.

Cheers.

I didn't fix the Command Console Errors yet, but i did fix the Plugin Folder and added some of your ideas.
I'll start to work on the other Bugs.

Cheers and thanks for the ideas

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

is it possible to return the message they would get if the server was down instead of telling them they are kicked? like a stealth/invisible mode?

i have a small server on my lan and i am in the process of setting it up/configuring things and testing plugins. my buddies seem to have a knack for randomly trying to log in at the worst times and catch me testing plugins or setting things up i dont want them to know about. it would be awesome to be able to make it appear to them that its just not running at all when i dont want anyone popping up, and open it back up to the 'public' when its time to play.

 

Sure, i just got home. I'll add that soon.

Cheers

 

Could someone explain to me the concept of this plugin?
I don't see why it would be used.

 

It's to be able to lockdown your server to keep people out. And there's certain Levels to do that.

Actully to do this, change the Kick Message in the config.yml to something like "No Connection to Host" and then set the server to Defcon 1 to kick any Players trying to join.

Cheers

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

I got that but I don't see when you would use it.

 

wonderful! thank you

 

No Problem!

 

What is the point of banning any players that join?

 

It's not really ban, but keeping people out of your server. Everything is configurable.

 

the config file/folder were not created on start so i made \plugins\MCDefcon with config.yml in it and copied your example from the first post. i tried to connect when the server was not running to see what it says (which is 'Connection refused: connect'). turns out the : causes the plugin to fail to load. i guess there is nothing which can be done about that though as the : throws everything off. as a test i just removed the : and it loads fine, but i still get the default 'kicked defcon level 1' msg when i try to log in with a second client. for me, i dont think this will work the way i wanted anyway, because when the server is down the top line (which you cant change) of the error says 'failed to connect' and even if defcon was using my custom msg, that top line says 'server refused' or similar...an observant player would know something was up =)

so thanks anyway. consider this post a quick error report i guess. here is the cfg, error (caused by having a : in my msg) and other relevant info. let me know if you would like to see anything else or have me test something.

im on bukkit 1031 and my config/yml is:

Code:

Defcon Level: 0
Use Bukkit Permissions: false
Broadcast Level Change: true
Level 1 Message: Connection refused  connect
Level 2 Message: Banned. Defcon Level 2.
Kick All Players on Defcon Level Change: false
Use McBans: false
McBans Temporary Ban Time: 5m

error msg:

Code:

2011-07-28 08:20:35 [INFO] [MCDefcon] Loading MCDefcon Version 1.0
2011-07-28 08:20:35 [INFO] [MCDefcon] Loading Configuration File.

Yet the folder MCDefcon does not exist, no config...

 

Um.. the download link leads to Defcon 1.0, not 1.5. That might be why theres no config or level 3

 

... Sorry, i changed the name of it, It know Works with 1.5

===UPGRADE TO 1.5===

• Creates folder
• Added Defcon 3
• Fixed more Bugs

Linkes Fixed to 1.5. Sorry :/

Cheers.

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

awesome thanks =) ill check that out in the morning

 

Shouldn't DC 3 be local bans, DC2 be temp bans? Temporary bans are less "heavy" than local bans I'd say

Config works now

 

Haha i might switch it, Though i will add defcon 4 for mutes and defcon 5 for no building. xD.

Thanks for using the Plugin. Enjoy!

Cheers!

 

works perfect now =) custom msg is delivered, folder and config generated with no errors. thanks for the quick fix

 

I still don't get what this is useful for.

 

Then don't worry about.

 

MCBans seems really like a ban to me.

 

hello, awesome plugin, is possible in the next release implement commands by console?

i tryed to use in console and i got this error:
