About DDOS Attack

my firends got problem with server laging, i got ping for 200ms to his server, first trying to run the server with 60 user, there is no problem, but at a few months the problem come.

every minutes the server always lag, and some times it disconnected client from server, but it always got lower than 200ms ping.

first time i think it was cause his server, but the server have 16Gb Ram with Quad Core @2,5ghz, and have 500Gb hdd. and i think it not cause from server, then i think again, maybe from ISP. if it from ISP, why it always got lower than 200ms ping

or it was posible from DDOS attack?

can someone help on this?

btw his server using UBUNTU

thx :):

Net connection speed?
If good enought, how far client from server?
If in one town or (better) in one local network, how about iptables configuration (drops, denies etc)?

DDOS attack has no solution, Cisco helps more protection is not 100% guaranteed, you should be aware of the attack and the time to contact the Data Center to make it a general blockade, DC All of the reputable support these cases.

From a look at memory usage of your machine if it is not climbing alone.

1. you need increase your connection
2. if you got ddos more then your connection, you still lose.
( your connection 100Mbps > got ddos 200Mbps = Down )
3. if ddos type is http flood, you will got *10 connection feedback
4. use proxy shield ( $10000/mo :) )
5. use cisco ( f*cking firewall )
6. firewall just working when you still have more connection. when all your connection distributed by denial of service. no one can help you.

1 solution = NULL ROUTER :thumbdown:

200ms delay, the worlds most deadly ddos attack, lol....

USA Government has ever overwhelmed by the ddos attack :mad:

Agree with 1 and 5. '-' 2gb uplink failure most of the attacks and Cisco Firewall f*cking the remains.

the client and distance only 1 meter from server, that was my PC besides his server(Home, his my neighborhood), but using different IP ISP and modem's

and still no luck with that condition, if server running for more than 3 hours, it will be laging, but the ping still normal. even only one user connected.

1. the connection already good with bandwith 10 mbps from my local ISP, and it runs smooth with 60 users at leas for 3 hour.

4 using proxy shield for $10000/mo >.< this is realy expensive at my country, more than my salary working at the office >.<

i only using standar firewall that i got from ronny tutorial, and only open port 29000, and for port 8080 that can only access local.

hmmmmm... what about if i change the operating system from UBUNTU to Debian? will it solve this case??? :blink:

thx for all your quick respond

Hrace009, server temanmu kena serang hacker ya? serverku juga dalam 1 minggu ini lagg terus sampai DC, aku uda coba pakai comodo firewall, antiarp, iptables firewall, tapi semua gk mempan, masih kena serang juga, semoga lo dapat solusinya deh.... kalo ada solusinya di share ya?

Contact your Data Center, remember that consumes bandwidth attack, you can have a very bad surprise at the end of the month. My problem was solved attack after two weeks of intense attacks by the company, after going to end up blocking.

yeah.. contact your datacenter to get more bandwith, 100Mbps = $500/mo
if you got ddos 200Mbps so u will pay $1000/mo, if got ddos 1Gbps you need to pay $5000/mo. only thats solution, they not pay bandwith for dos, but we must pay bandwith because ddos, if dont believe. you can ask to hosting community/to datacenter about ddos, and they will say to you. 1 solution!! money ;)

that was imposible, at my country to got 3mbps bandwith you must pay about $100 - $200, i can't calculate it if 100mbps @_@

looks like the server will be moved from house to hosting company

Omg where you all life O.o

I have 1000Mbps/s for 60€... for around 81,91$ per month hm wierd.

Maybe its because of the country. But not sure.
