Help! i want to modify npcs and other things

[nitrux]

Well, i need some help to:
change buffs time duration
Put or remove some items in my gmshop
change some spawning zones (like primeral island, i want ppl appears at the beach for example, the problem is that i dont know how to know my coordinates (x,y,z))

And i want to know this, if i put my server online, but for my friends only (3 or 4, only for test)... i have to install a port security or something similar? i only have NOD32 at my pc... but im not shure if its 100% secure, some else can join my server and take my ip and destroy my pc :p
I supose that its secure but i`ve never try before... i thing asking is the best solution.

PD:sorry for mi bad english... im Argentinian, if you can speak spanish.. do it :D

lets take for example skill id 271 "Dance of the Warrior".

<skill id="271" levels="1" name="Dance of the Warrior" enchantLevels1="30" enchantLevels2="30" >

</skill>

3600 is 1 hour
the same you do with other skills just find them!

put items or remove is db thing.. you'll find out how:)

Here's a little trick I know for finding out coordinates:
Spawn an npc where you wanna player to spawn .... press click + shift on npc and check coordinates, note them somewhere. Then delete the npc.
and insert coordinates on appear place you want:)

Good luck with your server!
