Have you ever wanted to know what httpd a website is using but didn't know how? this tutorial will be able to show you. You can simply find out the httpd by viewing the servers header. To view the headers we need curl you can install it by running the following command
apt-get install curl
Then we need to launch it with the switch -I so lets say we want to find out the httpd that tuts4tech.net uses we would type the following
curl -I tuts4tech.net
Output:
HTTP/1.1 200 OK Vary: Cookie Set-Cookie: wordpress_test_cookie=WP+Cookie+check; path=/ X-Pingback: http://tuts4tech.net/xmlrpc.php Content-Type: text/html; charset=UTF-8 Date: Sat, 20 Jun 2009 17:29:21 GMT Server: lighttpd/1.4.19
From the output you can see that we use lighttpd
You can also just use this script http://tuts4tech.net/httpd.php?domain=tuts4tech.net
