TheHippo

Just for fun I looked at the headers generated by website I made and where I am responsible for the administration of the Apache server I discovered this:

HTTP/1.1 200 OK
Date: Sun, 06 Sep 2009 11:44:56 GMT
Server: Apache/2.2.8 (Ubuntu) DAV/2 SVN/1.4.6
X-Powered-By: PHP/5.2.4-2ubuntu5.7
Connection: close
Content-Type: text/html

Actually I think no one needs to know which PHP version is running on this machine and that there also a Subversion is running on that machine. Even the name of the operating system and the version of the Apache is not needed in most cases.

So how suppress these information?

After leaving my last company I rented a small virtual server at 1und1. I took the XL vHost package which contains:

• 20 GB Raid 5 Storage
• 512 MB RAM, max 2 GB RAM
• 2 TB Traffic

At this time I thought it would be nice to install every thing by myself, so I choose a plain “Ubuntu 8.04 LTS 64 bit minimal” as operating system for my vHost. I installed Apache2, PHP5, MySQL and all the stuff I needed. It all works fine and I was really impressed by the speed of this virtual server.

Then I moved sportinleipzig.de, which I made during the time at my last company to this new server. This page does not have a very high traffic (200 unique visitors a day), but a lot of content (at least 5000 “static” pages). After 2 days the server crashed the first time, whereas crash means, that he is still alive, but does not respond to anything more then a simple ping. I restarted the server over the admin panel. Half a week later the server crashed the next time. Investigating the cause for these crashed I found out a few interesting things. continue reading…
