We are freelance political activists running a web News magazine. It is running on appache server powered by wordpress. Currently we host our site on linode.
As a part of recent oppression on freedom of expression in india we face attacks, hacks and malicious attacks every day.
Previously, our site was down and we identified from the logs that was a DDoS attack. But now our site is getting down. This time when we checked our Appache server log files we are dont have any clues that what was happened.
In all of our logs, when the website was down, it shows binary pattern of NULL for the down time.
Please help us to understand our problems.
Regards, |

Sorry, please follow the forum rules. For example the subject is not meaning full. And version Apache etc.
And the description of your problem is a little vague, be more specific. |

DDos sends to many requests at once so that the process, in this case apache, can't handle it and breaks down.
You can try to block your attackers by firewall level
e.g.
| Code: | | sudo iptables -I INPUT -s 1.81.0.0/16 -j REJECT |
if that still isn't enough you might use a service like mod cloud flare or so. |

hi,
Thanks for replies..
Sorry for posting topic as too vague.
Actually we contacted Linode. Our server is running on Xen platform of their data center. they said xen platform and kernel got some issues. So, they adviced us to migrate / upgrade to KVM.
We did the same and our problem solved.
We suspected our web server setup, thats why i posted here.
anyways thanks for you support. |
