DDoS in FreeBSD 6.2-STABLE And Problen With The Clock

[ExTaZyTi]

There are some problems, first DDoS (hardware DDoS) in the system.
I compile some program and when start it my system blocks and restart
(tested and on other system 6.2-stable and again this DDoS).
To prevent users from DDoS some systems i not going to upload this program
in the web.
The next DDoS (I don't know about his..) somebody (..any "h4x0r") send every
day to me hardware DDoS attack .. then my system full block and drop my
interner connection, when i try to RE-ENABLE my connection to the DHCP
server it's says "connecting.." without any answer i think it's becouse my
server is full blocked.. I have open this ports :
 53(domain..standart..), 25(mail servers..), 80(apache), 110(mail
servers..), 113(identd), 443(apache), 6666(ircd), 6667(ircd), 7000(ircd),
9000(ircd) .. i can't find the DDoS.. please somebody to help me this
"hardware" DDoS to my system.
Next problem is the clock, have e 4 minuts different from the world time for
my country. I try to fix this with a "ntpdate otel.net" for example ..  this
again return 4 minutes different. I try and the "date" command but it's NOT
WORK..You can see:

[root at extremebg (~)]: date 0706111826.40
date: can't reach time daemon, time set locally
Mon Jun 11 18:26:40 EEST 2007

root at extremebg (~)]: date
Mon Jun 11 18:23:55 EEST 2007
[root at extremebg (~)]:

..now example for "nptdate":

[root at extremebg (~)]: ntpdate otel.net
11 Jun 18:25:08 ntpdate[5157]: step time server 212.36.8.133 offset
218.607216 sec

 [root at extremebg (~)]: date
Mon Jun 11 18:25:09 EEST 2007

but the "original" world time for my country is: 18:28:58...
