Help about UDP Attacks
Hello, Im the admin of israeli.as IRC Network. the system is Working this way: 1.Windows NT 5.0 Updated and secured Runing on Intel Celeron 533Mhz 128MB RAM 2.P166 Packerd Bell LINUX Machine, Caldera. the NT is the Gateway of the network. the nt protected with ZoneAlarm firewall. all things are tesetd and all fine. some one with Linux Machine from EDu flooding us by UDP Attacks, and making the system Havy, means: the CPU is working in 100% and it is hot. very hot memory is 50% Free of 128MB ram the linux has no problems at all. its fully secured and inetd process are closed for best secureing. all packges are updated,and we are connectd with 3 nics [eth cards] 10/100 now whan he flooding the system beging to be slow very slow. now i orderd new server AMD 500Mhz 256MB RAM Nvdia GeforCE 2 64MB Ram card. 20GB HD and thing blah does its will be strong for server? and does it will be almost not effacetd from the UDP ports attack? all ports of UDP are closed but yet he is scaning port and port and trying to attack it here is log FWIN,2001/10/08,18:58:20 +2:00 GMT,211.220.194.252:1026,192.117.101.174:2535,UDP FWIN,2001/10/08,18:58:21 +2:00 GMT,211.220.194.252:1026,192.117.101.174:1645,UDP FWIN,2001/10/08,18:58:21 +2:00 GMT,211.220.194.252:1026,192.117.101.174:445,UDP FWIN,2001/10/08,18:58:25 +2:00 GMT,211.220.194.252:1026,192.117.101.174:13,UDP FWIN,2001/10/08,18:58:26 +2:00 GMT,211.220.194.252:1026,192.117.101.174:3001,UDP FWIN,2001/10/08,18:58:27 +2:00 GMT,211.220.194.252:1026,192.117.101.174:7,UDP FWIN,2001/10/08,18:58:30 +2:00 GMT,211.220.194.252:1026,192.117.101.174:137,UDP FWIN,2001/10/08,18:58:31 +2:00 GMT,211.220.194.252:1026,192.117.101.174:1025,UDP FWIN,2001/10/08,18:58:32 +2:00 GMT,211.220.194.252:1026,192.117.101.174:1646,UDP FWIN,2001/10/08,18:58:33 +2:00 GMT,211.220.194.252:1026,192.117.101.174:3372,UDP FWIN,2001/10/08,18:58:34 +2:00 GMT,211.220.194.252:1026,192.117.101.174:515,UDP FWIN,2001/10/08,18:58:38 +2:00 GMT,211.220.194.252:1026,192.117.101.174:17,UDP FWIN,2001/10/08,18:58:38 +2:00 GMT,211.220.194.252:1026,192.117.101.174:13,UDP FWIN,2001/10/08,18:58:39 +2:00 GMT,211.220.194.252:1026,192.117.101.174:7,UDP FWIN,2001/10/08,18:58:40 +2:00 GMT,211.220.194.252:1026,192.117.101.174:2535,UDP FWIN,2001/10/08,18:58:41 +2:00 GMT,211.220.194.252:1026,192.117.101.174:3372,UDP FWIN,2001/10/08,18:58:41 +2:00 GMT,211.220.194.252:1026,192.117.101.174:1645,UDP FWIN,2001/10/08,18:58:43 +2:00 GMT,211.220.194.252:1026,192.117.101.174:137,UDP FWIN,2001/10/08,18:58:46 +2:00 GMT,211.220.194.252:1026,192.117.101.174:3001,UDP FWIN,2001/10/08,18:58:49 +2:00 GMT,211.220.194.252:1026,192.117.101.174:515,UDP FWIN,2001/10/08,18:58:50 +2:00 GMT,211.220.194.252:1026,192.117.101.174:138,UDP FWIN,2001/10/08,18:58:53 +2:00 GMT,211.220.194.252:1026,192.117.101.174:1813,UDP FWIN,2001/10/08,18:58:57 +2:00 GMT,211.220.194.252:1026,192.117.101.174:9,UDP FWIN,2001/10/08,18:59:01 +2:00 GMT,211.220.194.252:1026,192.117.101.174:135,UDP FWIN,2001/10/08,18:59:01 +2:00 GMT,211.220.194.252:1026,192.117.101.174:1723,UDP FWIN,2001/10/08,18:59:02 +2:00 GMT,211.220.194.252:1026,192.117.101.174:445,UDP FWIN,2001/10/08,18:59:04 +2:00 GMT,211.220.194.252:1026,192.117.101.174:3002,UDP FWIN,2001/10/08,18:59:04 +2:00 GMT,211.220.194.252:1026,192.117.101.174:1025,UDP FWIN,2001/10/08,18:59:04 +2:00 GMT,211.220.194.252:1026,192.117.101.174:13,UDP FWIN,2001/10/08,18:59:04 +2:00 GMT,211.220.194.252:1026,192.117.101.174:1646,UDP FWIN,2001/10/08,18:59:07 +2:00 GMT,211.220.194.252:1026,192.117.101.174:1812,UDP FWIN,2001/10/08,18:59:10 +2:00 GMT,211.220.194.252:1026,192.117.101.174:2535,UDP FWIN,2001/10/08,18:59:14 +2:00 GMT,211.220.194.252:1026,192.117.101.174:515,UDP FWIN,2001/10/08,18:59:16 +2:00 GMT,211.220.194.252:1026,192.117.101.174:3001,UDP FWIN,2001/10/08,18:59:18 +2:00 GMT,211.220.194.252:1026,192.117.101.174:137,UDP FWIN,2001/10/08,18:59:18 +2:00 GMT,211.220.194.252:1026,192.117.101.174:1645,UDP FWIN,2001/10/08,18:59:21 +2:00 GMT,211.220.194.252:1026,192.117.101.174:3372,UDP FWIN,2001/10/08,18:59:22 +2:00 GMT,211.220.194.252:1026,192.117.101.174:1813,UDP FWIN,2001/10/08,18:59:24 +2:00 GMT,211.220.194.252:1026,192.117.101.174:3002,UDP FWIN,2001/10/08,18:59:25 +2:00 GMT,211.220.194.252:1026,192.117.101.174:1723,UDP FWIN,2001/10/08,18:59:31 +2:00 GMT,211.220.194.252:1026,192.117.101.174:20433,UDP FWIN,2001/10/08,19:05:57 +2:00 GMT,211.220.194.252:1026,192.117.101.174:911,UDP FWIN,2001/10/08,19:05:57 +2:00 GMT,211.220.194.252:1026,192.117.101.174:88,UDP FWIN,2001/10/08,19:05:57 +2:00 GMT,211.220.194.252:1026,192.117.101.174:21910,UDP FWIN,2001/10/08,19:05:57 +2:00 GMT,211.220.194.252:1026,192.117.101.174:50594,UDP FWIN,2001/10/08,19:05:57 +2:00 GMT,211.220.194.252:1026,192.117.101.174:59749,UDP Thanks you Israeli.as [email protected]
