Avoiding the Web Hosting Nightmare

Ultimately, the true test of a web host comes from your own experiences with them. With this article, I wanted to compile some of the experiences of a few people to bring to you cautions when choosing a host: clients, friends, and myself.

Dealing With Distributed Denial of Service Attacks

Distributed denial of service attacks are frustrating — they’re frustrating for the company under attack, and frustrating for the web host. They can also be costly in terms of business and goodwill lost. Fortunately, there are ways to deal with them, if you are willing to prepare for the possibility of a DDoS before it happens.

Stop PHP nobody Spammers

PHP and Apache has a history of not being able to track which users are sending out mail through the PHP mail function from the nobody user causing leaks in formmail scripts and malicious users to spam from your server without you knowing who or where.

cPanels fix for perl

John Wigle reports : This email was sent out to all of those who directly purchase cPanel licenses, of course if you are like most people and do not directly own a license but get it through a datacenter you never got this email.

HELP! My server is under a DDOS attack!

Ok first just take a breath, you are getting nothing done by worrying. This guide is meant to try and help mitigate the effects of an attack that is in progresss. I have compiled a lot of the things that I do but it is very possible I have forgotten something. Please feel free to add suggestions at the bottom if you would do it a different way or if this works good for you.

A lot of this requires you to have an idea of what is happening with your server on a normal basis so you can see what is abnormal with it. It would not be a bad idea to run a few of these tests to see what is normal under your normal busy periods.
