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@extremebg (~)]: date 0706111826.40 date: can't reach time daemon, time set locally Mon Jun 11 18:26:40 EEST 2007 root@extremebg (~)]: date Mon Jun 11 18:23:55 EEST 2007 [root@extremebg (~)]: ..now example for "nptdate": [root@extremebg (~)]: ntpdate otel.net 11 Jun 18:25:08 ntpdate[5157]: step time server 212.36.8.133 offset 218.607216 sec [root@extremebg (~)]: date Mon Jun 11 18:25:09 EEST 2007 but the "original" world time for my country is: 18:28:58... can somebody help me to fix this errors.. please!

If you use the correct timezone (you can set this by running tzsetup) this should not be a problem. -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."
