DDos attack on my forum?
I believe a ddos attack is occurring on my forum.
At the moment, I am getting multiple connections (about 50 - 100) from around 50 different IP addresses. Both numbers grow every minute. All the IP addresses I traced back seem to come from ; IP country code: US IP address country: United States IP address state: Florida IP address city: Lake Worth That is most of the locations, however some are from different areas of the US, and some are from the UK. Is there anyway to stop this attack? How long do you think it will last? |

Your host may be able to help with this, so you may want to talk to your host about it.
There is no way to tell how long it can last. |

Can you post a few of these IP's?

Most of them began with 98.77.xx.xx
So for the mean time, I blocked out all 98.77. connections and the other ones.

see, they are either from; If you are willing to block the IPs, use the below layout as it will stop all the IPs ddossing; 98.77. 74.233. 98.64. 65.8 194.204 Doing it this way will range them. When experiencing a ddos attack, I suggest you check IPs, if they are similar to this, then block them using .htcaccess for a few days. I have managed to stop it for the mean time, and will unblock them in a few days. |

What type of server do you have? Dedicated VPS, or are you a Shared Web Hosting? Assuming you've gotten all the IP's you must be on Dedicated or VPS. I suggest installing CSF or APF firewall. They are Iptable scripts that can stop/block IP addresses. If you have the the money (and your data-center offers it) you can always setup a hardware firewall such as a Cisco Guard to help filter legitimate traffic.
Good Luck man! |

It isn't unusual for a busy site to be accessed by a group of machines looking for links, or email addresses to scrape. If it bothers you, there are some firewall options that will dynamically block IPs that reach a particular number of connections and then release them when activity subsides - but you may be blocking legitimate users or search engine spiders by doing so. It's a feature best used for real-time databases of hacked networks or blacklisted IP addresses.
An actual DDOS would flood server's network interface. If the target was actually your site you would see hundreds of connections (if any). The last time I was attacked vbulletin was showing only a few users, but my webserver had queued hundreds of instances. |
