Prevent and Stop DoS or DDoS Attacks on Web Server (D)DOS-Deflate Novērstu un apturētu DoS un DDoS uzbrukumi Web Server (D) DOS Deflate
All web servers been connected to the Internet subjected to DoS (Denial of Service) or DDoS (Distrubuted Denial of Service) attacks in some kind or another, where hackers or attackers launch large amount connections consistently and persistently to the server, and in advanced stage, distributed from multiple IP addresses or sources, in the hope to bring down the server or use up all network bandwidth and system resources to deny web pages serving or website not responding to legitimate visitors. Visu web serveri ir savienots ar internetu pakļauti DoS (Denial of Service) vai DDoS (Distrubuted Denial of Service) uzbrukumus sava veida vai citā, kur hakeri vai uzbrucēju uzsākt lielu savienojumu konsekventi un neatlaidīgi uz serveri, un gandrīz pilnībā , izplata vairākas IP adreses vai avotiem, ceram pazemināt servera vai patērē visu tīkla joslas platumu un sistēmas resursus, lai liegtu interneta lapas, kas apkalpo vai tīmekļa vietne, kas nereaģē uz likumīgu apmeklētājiem.
There are plenty of ways to prevent, stop, fight and kill off DDoS attack, such as using firewall. Ir daudz veidu, lai novērstu, apturētu, cīnīties un nogalināt off DDoS uzbrukumiem, piemēram, izmantojot firewall. A low cost, and probably free method is by using software based firewall or filtering service. Zemu izmaksu, un, iespējams, bez metodi, izmantojot programmatūru balstītām ugunsmūra vai filtrēšanas pakalpojumu. (D)DoS-Deflate is a free open source Unix/Linux script by MediaLayer that automatically mitigate (D)DoS attacks. (D) DoS-Deflate ir bezmaksas open source Unix / Linux skripts ar MediaLayer kas automātiski mazināšanai (D) DoS uzbrukumiem. It claims to be the best, free, open source solution to protect servers against some of the most excruciating DDoS attacks. Tā apgalvo, ka ir labākais, bezmaksas, open source risinājumu, serveru pret dažiem visbiežāk excruciating DDoS uzbrukumiem.
(D)DoS-Deflate (D) DoS-Deflate script basically monitors and tracks the IP addresses are sending and establishing large amount of TCP network connections such as mass emailing, DoS pings, HTTP requests) by using “netstat” command, which is the symptom of a denial of service attack. skripts būtībā uzrauga un dziesmas IP adreses tiek sūtīt un izveido lielu daudzumu TCP tīkla savienojumus, piemēram, masveida e-pastu, DoS impulsus, HTTP pieprasījumiem), lietojot "netstat" komandu, kas ir simptoms ir noliegums pakalpojumu uzbrukums. When it detects number of connections from a single node that exceeds certain preset limit, the script will automatically uses APF or IPTABLES to ban and block the IPs. Ja tā atklāj vairākus savienojumus no viena mezgla, kas pārsniedz noteiktu iepriekš noteiktu limitu, skripts tiks automātiski izmanto APF vai iptables aizliegt un bloķēt IP. Depending on the configuration, the banned IP addresses would be unbanned using APF or IPTABLES (only works on APF v 0.96 or better). Atkarībā no konfigurācijas, aizliegtas IP adreses būs unbanned izmantojot APF vai iptables (darbojas tikai 0,96 APF v vai labāk).
Installation and setup of (D)DOS-Deflate on the server is extremely easy. Uzstādīšanu un iestatīšanu (D) DOS Deflate par serveri ir ļoti vienkārši. Simply login as root by open SSH secure shell access to the server, and run the the following commands one by one: Vienkārši piesakieties kā root ar atklātu SSH Secure Shell piekļūt serverim, un palaist šādas komandas pa vienam:
wget http://www.inetbase.com/scripts/ddos/install.sh
chmod 0700 install.sh
./install.sh
To uninstall the (D)DOS-Deflate, run the following commands one by one instead: Atinstalēt (D), DOS Deflate, palaist šādas komandas pa vienam, nevis:
wget http://www.inetbase.com/scripts/ddos/uninstall.ddos
chmod 0700 uninstall.ddos
./uninstall.ddos
The configuration file for (D)DOS-Deflate is ddos.conf , and by default it will have the following values: Konfigurācijas failu (D), DOS Deflate ir ddos.conf, un pēc noklusējuma tas ir šādas vērtības:
FREQ=1 FREQ = 1
NO_OF_CONNECTIONS=50 NO_OF_CONNECTIONS = 50
APF_BAN=1 APF_BAN = 1
KILL=1 KILL = 1
EMAIL_TO=”root” EMAIL_TO = "root"
BAN_PERIOD=600 BAN_PERIOD = 600
Users can change any of these settings to suit the different need or usage pattern of different servers. Lietotāji var mainīt jebkuru no šiem iestatījumiem, lai atbilstu dažādu vajadzību vai lietošanas modeli dažādiem serveriem. It's also possible to whitelist and permanently unblock (never ban) IP addresses by listing them in /usr/local/ddos/ignore.ip.list file. Tas ir arī iespējams whitelist un pastāvīgi atbloķēt (nekad aizliegums) IP adreses, uzskaitot tos in / usr / local / DDOS / ignore.ip.list failu. If you plan to execute and run the script interactively, users can set KILL=0 so that any bad IPs detected are not banned. Ja plānojat veikt un palaist skriptu interaktīvi, lietotāji var iestatīt KILL = 0 tā ka visi slikti IP atklāti nav aizliegta.

I really doubt this will work against high Attacks. Es šaubos, tas darbosies pret augstajām uzbrukumiem.
I guess opting for any third party Anti DDOS service will be better. I guess izvēlas trešo personu Anti DDOS pakalpojums būs labāk.

Great information. Lieliska informācija. There is a DDOS running right now of mostly South American IP's. Ir DDOS darboties jau tagad galvenokārt Dienvidamerikas IP's. Somebody must have put a trojan on spanish language sites. Kādam ir jābūt nodot Trojas uz spāņu valodu vietnēs.
