But as mentioned, a lot of attacks can be stopped simply by proper tuning of your IP stack and some simple firewall rules.
My question is as a new Dedicated Server Owner what tuning and rules do I need to implement in order to protect me from these "small scale DDoS Attacks"?
I do not run a DDoS prone site(i hope not lol) but I want to secure myself as much as possible and have a headache free run other than the headaches I cause myself of course.
Understanding DDOS Attacks
Aug 3, 2009I want to understand the mechanics of a DDOS attack. I have been doing a lot of reading about them this weekend.
The way I am understanding it, a DDOS attack is done at the network level. It may be requesting that pages from a given website, or websites, are served up, but it basically will effect the entire network. So if 'page display' requests are made to a website(s) that is hosted at ABC Hosting (example only), to the tune of 15GBs then I have to assume that the network will be terribly degraded. If that is so, wouldn't other servers also get taken out?
I believe the architecture of the internet is something like this (example only):
Gnax --> Planet, SoftLayer, RackSpace, etc.. --> Reseller --> Smaller Reseller --> Me
If that is true, is each level along that route using their own networking system or are they all dependent on ones that major Data Center uses?
Ddos Attacks And A New Webhoster
Jan 12, 2009My current site has been taken offline since it was being ddos attacked, been with my current hosters for 3years at least, but with recent events they gave me the option to shift my site to a dedicated server or me to move of bascially. (impression I get now, since they seem to be taking longer to reply to my messages) I was being ddos attacked since I refused to give a copy of me software to the visitor at my forums/site.
ive been looking round site after site and I cant make up my mind who to shift too, also if that same idiot who ddos attacked me does it again before I can take any action, I would be in the same situation again.
I have multiple domains and all my sites in total are about 5gig in size, cpu usage is avergae and queries roughly about 15/17 the most, I currently pay £130.00 a yr
I have had few bad experiences with hosting companies but learnt along the way, and assumed my current hosters would be a reliable place to stay at. My sites been offline since friday and I would like to get it back up again asap. Last thing I want to do is rush into a hosting package and be stuck in a dud situation.
I would also like to take action upon the person who has been ddos attacking me, I managed to get hold of his details and I also have confirmation that they are correct, what can be done legally?
Best Firewall For DDoS Attacks
Mar 23, 2009My sites are getting heavy DDoS attacks.
What's the best firewall? I'm currently using ACH software firewall but the attacks are getting so bad my site's are going down (apache is shutting down/locking) and sometimes my server even crashes.
Anyone recommend a better software firewall or a really cheap but good hardware firewall?
Could my host just use a router or something as the firewall or would that not do? I'm looking for something really affordable as a solution.

Mar 18, 2008As many of you already know, not everyone has the money to spend on physical firewalls, for example a cisco firewall. I would like if everyone could share little tips and tricks towards securing a server they learned over time. Nothing in big detail. I thought if we all share our ideas, it would help quite alot of other people. For example, here is a good layout I believe. Please note this is towards a game server setup.
Shorewall Firewall - Block Unneeded Ports + Block Ping
Apache Web server - Installed with "mod_security"
SSH-Faker - Stop thoes bots from trying to gain access to SSH (Guessing Passwords)
DDoS Deflate - For me, does not really work. (I know, mainly for port 80 so webhosting) But still have it installed.
Bash Scripts Monitoring # of connections per ip with Netstat.
PSad - Monitoring and Reporting Port Scans (Optional automatic timed block)
VNStat - Monitor Current/Monthly/Yearly Bandwidth (Does not hog resources)
I'm guarenteed to of left alot out than just the above. If some of you could also share some simple things you do for securing a server, would be great.

Jan 12, 2008Can you restart the httpd to get the server online again while you are under an DDoS attack?
The reason for asking is that I was told that when restarting the httpd it should start to work again instantly, and so it seems.
But why? doesnt the attack "continue" after the restart?
Security To Stop DDoS Attacks And Stuff
May 19, 2009My host tells me that they have security to stop DDoS attacks and stuff, however today my server load jumped to 17.12 and my site went down giving me a "Network Timeout" error.
My host tells me it's my fault that I am using too many resources. The MOST my site has been on load is 3.06 and that was around lunch time a few weeks back. It's 11:43 and the server load is 17.12? I think my host is pulling my leg. I have not added ANYTHING new to my site and have not changed anything in 3 days. The load has been fine till today.
I use In Motion Hosting.

Colo Provider That Handles DDoS Attacks
May 21, 2007One of the sites I run is a forum with a political component, and 4-5 times over the last week we've been seeing DoS attacks. They're not terribly sophisticated -- generally 1-3 compromised servers throwing packets my way -- but they're enough to clog my pipes and take my sites down.
What I'd like to do is put a new server up at a data center that's D(D)oS aware that can hopefully respond to these attacks automatically. My current provider has been giving solid support, but the best they can do is null route the affected IP, rather than filtering the incoming attack.
Can y'all name a few providers I should look into? Right now I'm just looking to move 1 box (or maybe a box and a firewall depending on the setup).
Reliable Hosting Provider That Protects Against DDOS Attacks
Dec 26, 2008Can someone please recommend a hosting company that offers 24 hours toll free phone support with very good DDOS protection services?
Our server has been attacked for the past couple weeks and current host can just null route the IP being attacked but cannot offer anything beyond that...which does not help us. We are talking about large 3 GBPS attacks.

A Better Deal Than 10tb.com
Mar 24, 2009I have a 100 mbps unmetered dedicated server + cpanel = $425 in 10TB.com and I would like to hear if you guys can advice me on a better deal, I have seen lately great offers for less, so I wonder if I am paying more than the average for a 100 mbps unmetered dedicated + cpanel. I don't complain service is good, well theplanet was better but even more expensive.
I have an adult video site so all i need is bandwidth.
I appreciate your feedback on current prices and what i paid there. $425 for unmetered 100 mbps dedicated + cpanel is okay? paying a lot more? After all 10tb is a reseller, so should i go to another reseller that charge less?

View 8 Replies View RelatedHow Do You Deal With Too Much Bot Traffic
Oct 28, 2008Recently I noticed the load on one of my servers way beyound what I would expect it to be. I run multi processor servers and even during a backup the load is only around 1.5.
But lately I noticed peak loads that high under normal web traffic.
I know 1.5 is low on an multi processor server, but I am hoping to add much more to those machines and with sustained load that high it leaves no room for expansion. The servers are not cheap, so adding another server to the cluster can only be done if I make money from the last one I added.
I checked the traffic levels and they were very high. After further review I had some bots hitting sites at over 1200 pages a minute. Multiply that by a few hundred bots and clearly I could have a load issue. The potential is there to bring any server to its knees when delivering those volumes.
I created programing to watch connections and block the abusive bots. While logging I became aware of over 600 bots crawling my servers. Many bots from, Japan, China, Germany and so on and on, useless to my customers even if they are legit search indexes.
Another problem I see is that the bots are running from many ip addresses and hitting the same sites from multiple ips at the same time. Why would the need to do that?
Among other things I decided to validate googlebot, msn and yahoo with dns lookups so I could determine that they were actually their bots and not imposters. In 24 hours I found valid bots from the big three hitting one server from 1100 different ips.
Now we are looking at thousands of vaild bots and thousands more email harvesters and content theives.
As a host, the number of sites I can host on a server is greatly reduced by the bot traffic. My customers do not want to hear that their website was being crawled at 3,000 pages a minute and that is why they could not access it. Of course they will blame it on me.
I was able to filter the bots at a firewall level and drop connections based on reverse dns lookups and site crawl rates and my server sits around 0.05 most of the time even with hundreds of pages a minute being accessed.
I am wondering how the rest of you hosts deal with this problem. Do you leave it up to your hosting customers? Or do you have some type of filter to get rid of the bots.
When you have a few sites it is not really a problem, but as you grow it grows exponetially out of control.
The Deal On Connections
Jan 7, 2007My site is hosted on Dreamhost and gets over 1 million hits a day. The site is highly optimized, so it can handle the load easily without slowing the server down. Most pages have a loading time of under 0.2 seconds.
However, Dreamhost is telling me now that I'm using up too many "connections" and have limited my connections to 150 every 3 seconds (or so they say). Now 503 errors are coming up left and right, and its highly annoying to me and my users. Oh, and Dreamhost has mentioned several times that I'm oh such a very good candidate to upgrade to $400/mo dedicated hosting (from $8/mo currently).
So my question is, is this connection restriction really a valid concern of Dreamhost or are they just trying to milk me for money because my site is popular?

How To Deal With Unixbench 4.1.0 WHT Compilation
Jan 21, 2007Whenever I try out a vps or dedicated the first thing I do is run Unixbench WHT on it.
I have been trying to compile on different systems a mixture of 32bit, 64bit, Fedora, Ubuntu etc, and in many instances the compilation fails the first time around.
e.g on a 32bit Ubuntu system I had to switch to gcc-3.4, instead of 4.0.3 for compilation to succeed.
Is there any place I can try and have this issues resolved when they arise?
Unsurprisingly it always appears to compile okay on 32bit Fedora/Centos Virtuozzo systems.
Best Banwidth Deal (with Quality)
Dec 14, 2008We've browsed/searched a lot these last years and I believe fdcservers has the best bandwidth deal, with stability and a good service.
We've been searching the last days and found some other companies (ex 10TB.com). Are there any other companies that would offer something as 'good' as fdc regarding bandwidth?
10TB says they use softlayer's DC but it seems they don't use their network (got that information on a chat with SL's sales) so in my opinion there is no benefits to be on SL's DC if we don't use their network which is really good/stable. We've found that 10tb.com is a new company and their site has 404 and incorrect contact e-mails address which made we 'quit' the signup process.. (and because it is hard to 'trust' a new company with lot of bandwidth - and errors on their website - when there are others on the market for a long time that couldn't offer it).
What do you think about 10tb.com? Other options? What about fdc? Is it worth going with them to host streaming ? We need as much bandwidth as possible, but we also need quality.
What Dedicated Server Deal Is The Best
Feb 29, 2008I'm thinking about a couple of different deals, and as I'm not a hardware expert I wondered if anyone could help me out with this.
Server 1:
Quad-Core Xeon X3220 2.4 Ghz/2x4MB (expensive)
1066FSB 2GB RAM ECC
500 GB SATA 7200 133 RPM
Server 2 (the cheapest):
AMD Athlon 64 X2 6000+ Dual Core
6 GB DDR2 RAM
2 x 750 GB SATA II
Server 3 (medium price):
Core™2Duo 2x2,0 GHz
3 GB DDR2 RAM
2x320 GB SATA
I have a website where each page is around 200KB and uses a simple MySql db. Around how many pageviews would each of the servers above manage a day? They are all 100mbit dedicated. What server is the best choice.
UK Hosting With Affiloate Deal
Apr 12, 2007I'm after a Linux shared hosting package with all the usuals: webalizer, php, mysql, phpmyadmin, subdomains, ftp accounts, that will give us a percentage when we refer a customer.
Basically every time we get a new client we'd like to get a little pay out for it.
We'd go for reliability over cost. Is anyone running anything like this?
