Well Using Apache It Can Be DDosed Off Very Easy If Not Setup Correct
Now Thing You Wanna Do Is
Set 25 Connections Per Ip
In Firewall
So That Only Allows Ip 25 Connections
Botnet DDos Attacks Always Use High Connections Like 50 - 100
And With It Set @ 25 It'll Ban IP Faster
Normal User Should Only Have 12 Connections To Server
APache Settings I Would Say How To But I Dont Have Apache Right Now
I Use Lite Speed
i am getting a huge DDoS attack in one of my servers they are botnets attacks came from Turkey's ip block where the computers have dynamic ips and every ip sends 1 packet 48 Byte and closing the connection To 80 22 110 25 ports so the machine became
unaccessiable because of the syn attack what would you advice do you advice cisco pix series or layeredtechs ddos protection PIX 501 Cisco PIX 501 Cisco PIX 501 - 1 Server Only - $99 Monthly Charge - $49 Set Up 99.0 i can buy this there are 1834 banned ips by the software firewall i am thinking is this cisco pix can handle a such attack
Our Security Technician found yesterday a 200 user botnet on a hidden IRC server and was able to quickly email the compromised systems information (just hostname) to our abuse email. So today i spent the last 2 hours sending emails off to web hosting companies, educational institutions and corporate companies telling them that their systems have been compromised, we regulary email out systems we have found compromised. The thing that stuns me is that most of the systems we found compromised on IRC are dedicated lines between 10MBPS to 1GBPS... I found a few hosting companies and will list them so they can be found by them:

i got botnet attack my web server...is there anything i can do to block thse attack? my host isnt help much?
View 4 Replies View RelatedBeen having an annoyance lately, This kid has been ddosing a site on my server for 3 days. It has absolutely no effect on the server besides filling up iptables rules and annoying the crap out of me with ip ban emails. So not really a problem as far as knocking my server offline but the guy has been trying for 3 days and its annoying as heck.
So I got someone to track the net down for me its located on
208.110.**
port 5050 and port 5520.
I will post the full details if it is ok with mods
So I emailed their abuse the other day, no response, tried calling, nothing but answering machines. Nothing has been done.
This guy must really have some connections inside datacenters because I was seeing where he had botnets on fdc, they got reported and fdc sent him the abuse reports so he could attack them some more!
[url]
Yes this really happened and fdc even protected the guys identity by editing his name and info out of the complaint post
Anyway, I get to talking to some other webmasters, he has had his botnet on wholesaleinternet a few months now. It has been reported repeatedly with no action taken, no one can even get ahold of anyone at the datacenter. So either they just ignore the same abuse report for months or they know exactly what he is doing and dont care. Either way they wont shut him down for nothing,
Ive sent reports to the registrar today, lets hope they are the ones to take action. And hopefully someone who works at wholesaleinternet will see this thread and finally be shamed into doing something. or if anyone knows anyone who works there please pass this on.
Staminus Communications has been hosting a botnet forum, which distributes bots, worms, trojans, illegal clickers, and tons more, 95% of the site is illegal, and is forbidden by Staminus's provider yet they could care less as long as they get there money, I sent an abuse letter August 17th 2009, they even admitted things were illegal on the site, I pointed out several like the Google Adsense clicker bot which is highly illegal and which is nothing close to the other content hosted and/or linked to.
They are hosting unkn0wn.ws they refuse to remove the site or make them remove the illegal content which is most of the forum, which now forces me to send a letter to there provider and the cybercrime which I am now doing.
Now I guess they do not care about what they host, only if the person pays, so I guess I'm just going to expose it here for everyone to notice, because it's just going to get there data center raided over time by hosting illegal content and not removing it.
Let's see what you guys think, or what the admins have to say when they read this post.
What do you guys think when a provider does nothing about illegal content do you think it's the employee's that are at fault or the customer?
on one my root server runs a DDOS attack, apparently from a Botnet, however all have the same Referer. Who can give me Tipps, how I can prevent the attacks? Preferably evenly stop over the Referer?
View 6 Replies View Relatedit's come under my attention that dragonara.net has been ddosing me today since morning from the ip:
194.8.75.229
What's so ironic about it is that the ip is from a UK DDOS protection site so i'm expecting some email with their services in the next hour or so. Stay clear of them they are fakes and e-terrorists.
I am looking for some good ddos protection providers, via protected dns. I've searched on internet, but most of them are really expensive.
Please tell me some ddos protection providers what could help me.(gige is too expensive btw).
And I found some ddos protection scripts. How can a script protected a server from ddos? A sript like CSF or DDoS deflate?
I've been getting VERY high packet loss to my VPS for around 10-15 minute periods over the past month or so (No patterns or specific times, totally random when it occurs) with my provider's Parallels Business Automation control panel reporting "Server is down" along with the VZCP on the node being inaccessible. I opened a ticket with my provider and they told me that they experienced a DDoS attack on the node my VPS was hosted on.
However, I get the feeling that they are giving me some crap to stop my pestering them about the packet loss all the time (I mainly use my VPS for providing VoIP services which use UDP so the packet loss is devastating).
Anyone got any views on this?
Also they keep offering to move me to a diffrent node but they say they can only do that by giving me a new IP address and I would have to backup all the data and restore it manually, myself. Any views on this as well?
I'm experiencing a significant UDP DDoS at the moment which is aimed at port 80 on my server, it's currently crippling Apache, but only on port 80, https (443) is fine. I've told iptables it drop UDP packets sent to port 80 and have also completely blocked most of the attacking IPs, this has helped, but the webserver is still periodically unresponsive.

View 3 Replies View Relatedwe had a bad ddos to on of the sites we were hosting, the ip of the ddos was blocked in apf and iptables, but for some reason it still got through we had to have it blocked in the router, we installed CSF into our server hoping for a better firewall does anybody know why apf could not hold back the ip im open to suggestions,
View 2 Replies View RelatedI have got pretty big problems with my VPS, some of my sites getting DDoS'd a log. I have no idea why and who DDoSing them
I have csf, apf and DDoS Delfate installed but it seems they can't take those attacks down. I know for mod_evasive but it works only on small attacks, I getting pretty strong attacks
I need some way to configure csf better, what I need to edit in /etc/csf.conf to block IPs if the same IP trying to connect to server more that 10 times. I need everything what I could edit for csf to block IPs faster
About DDoS Deflate, he is configured to works with apf, can I configure it to works with csf and how? How to configure DDoS Deflate better, to block IPs faster
Also, another problem with csf is that when I restart csf(service csf restart) he unblock all blocked IPs and I have to block them again
How to see blocked IPs by iptables?
I running lighttpd at the moment but I thinking to change it with Litespeed(free edition), what do you think about it?
I hope I will get some help here. Aslo,would be interesting to hear how do you guys protecting your servers from DDoS(if you getting DDoSed
we have a 100mbut connection and with a normal traffic we use about 40-50mbit but from friday seem that we are under attack this is the stats from the fastethernet
inbound 20427 ucast pkts/s
outbound 5547.5 ucast pkts/s
inbound 85793.9 Kbit/s
outbound 8211.98 Kbit/s
we have reach also for 4 hours 100mbit and all the server was offline, we have contact the datacenter and they say that not is a ddos attack because the traffic come fom our server and not from outside the net, so look as we have a hacked server that is making all this traffic, how can w found the problem? we have about 130 server on this connection
If you were under a DDos attack, what commands would you execute to confirm this?
Is it normal for high traffic sites with 3,000 concurrent apache connections from running this command?
netstat -n | grep :80 |wc -l
what would happen if you changed the server IP to 127.0.0.1?

The DC installed Squid. It manages the load fine but the php code on my page is cached and doesn't work.
Is there a way to get squid to not cache php? in that httpd can directly call php while squid does everything else?
Hey guys If there was a way to have the ips of the dedi change constantly would this help prevent ddos attacks or would there be no difference if the domain was being attacked.
View 2 Replies View RelatedOK well today I found out my server was being DDOS'ed
And I know which domain is being attacked with hundreds of IP's. I am running Cpanel / WHM but I have no idea how I can stop this?
Any ideas or suggestions? Maybe redirect the DNS? to a invalid ip? But I'm not sure how i can go about doing that?
I have a problem with a customer. For the last 48 hours he has been receiving a massive DDoS at his server. I tried blocking the darn IPs but they keep coming and with several hundreds of connections each:

Apache has over 14000 connections. I tried using mod_evasive but didn't do anything and the server has been out without httpd for hours now. Any advices? This is a Hsphere server (I hate it personally) with 4GB RAM and a dual optero 246. I have the mexclients setting at 550.
I have a windows server, and today it has a large inbound traffic, so I tried to disable all web service, and after that, the result of netstat -an shows no connection at all, but the server still has large inbound traffic,
Do you have any idea about this?
What should I do now?
Our server is in attack since 4 days. Http port busy all the time.
When I type :
netstat -na | grep ":80" | awk '{print $5}' | cut -d. -f1-4 | cut -d: -f1 | sort -n| uniq -c | sort -n | tail -5
It shows :
[root@ ~]# netstat -na | grep ":80" | awk '{print $5}' | cut -d. -f1-4 | cut
-d: -f1 | sort -n| uniq -c | sort -n | tail -5

5128

I wonder the hidden IP of 5128 ??? How to know it?
A user joined our live chat and said if we didn't cancel a domain on our server, he will send us a DDOS attack, and he did so and also did this morning.
Is there anything I can do to prevent this or possibly punish him?
The server getting slow with high I/O diskwait then normal, although load is not high.
here is the output of: netstat -anp |grep 'tcp|udp' | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -n .................
I want to understand the Idea of DDOSING
If I have a server with a a gb /second port so no one can DDOS me ?
or if the hacker have a servers with a gb/ port he can destroy any thing ?
second question
sometimes people hjave ip tables to filter all the packets to the server these people some times go down for ddosing too WHY ? why the IP tables cant filter the packets of this type of DDOSING?
My server is getting ddossed everyday, all are at the same time -> 4 am since tuesday.
Cacti is showing 60~70mbit on that time.
Server 'crashed' on thursday (nearly 70mbit), it got back up but the ips (4 out of 5) were not working. Couldnt ping it. So I gave it a reboot and it worked again.
I used to get alot of Brute Force attacks, after I changed port and not allow root login etc etc on Monday, I dont get any attacks anymore ...
i had installed anti ddos or firewall,but those are useless.His attacks are such great that The server and all the vps are down now. One told me that I should check the ips and receive ips. The attacker is so skillful .describe the best method to defeat him. Be sides the attacker use diffirenet ips in each attack,I block him by iptables but no use…. His attack occupy all the ram and I have to resetart the server… Now this time his attack lead to shutting all the vps down
View 10 Replies View RelatedMy website is under ddos attack from some competitors. I don't know yet how big is the attack. The ips of the ddos attack come from all the world.
I have contacted a few hosting companies specialised in ddos proof hosting, unfortunatly the price is so expensive that i cannot afford it.
So i try to find another solution : my website is only aimed to the french people, so maybe is it possible to install a kind of firewall or proxy located before the server to block all the incoming IP adress not from france ? Do you know some websites who can do this and the price ?
I already try do deny the non-french ip in one htaccess file but the ddos attack saturate the server anyway.
i'am looking for a software based ddos protection,some one know something for try to mitigate a ddos or help to get the server rock a solid?And i need to know too where i change the DNS(vhost) of my DEDICATED server.
