New to server management, questions and scripts

[xxblink 66]

We just set up our server yesterday, and I'm trying to figure all of this out. Our main purpose of getting our own server is to be able to deal with hackers better. I know this takes a lot of monitoring, but where do I look? I've got the scripts, I've got the createvehicles.log, where else do I need to look? I've been reading through those today in hopes of trying to see what is normal and what isn't, but is there some place where I can see what scripts are normal and what aren't?

Also, here are a few scripts that I found questionable....am I right in suspecting hacking?

dayzSetFix = [_vehicle,_selection,0];

publicVariable "dayzSetFix";

if (local _vehicle) then {

dayzSetFix call"

21.09.2012 01:53:50: - #28 "> "displayName");

dayzSetFix = [_vehicle,_selection,0];

publicVariable "dayzSetFix";

if (local _vehicle) then {

dayzSetFix call"

21.09.2012 01:55:24: - #28 "> "displayName");

dayzSetFix = [_vehicle,_selection,0];

publicVariable "dayzSetFix";

if (local _vehicle) then {

dayzSetFix call"

21.09.2012 01:56:47: - #28 "> "displayName");

dayzSetFix = [_vehicle,_selection,0];

publicVariable "dayzSetFix";

dayzSetFuel spawn local_sefFuel;

publicVariable "dayzSetFuel";

A bazillion of these:

21.09.2012 02:06:41: - #0 "eOf _flare) >> "displayName");

s_player_dropflare = player addAction [format[localize "str_actions_medical_16",_text], "\z\addon"

21.09.2012 02:06:45: - #0 "eOf _flare) >> "displayName");

s_player_dropflare = player addAction [format[localize "str_actions_medical_16",_text], "\z\addon"
