Linux app to find the HTTP server header

Synesthesia · 02-12-2007, 09:48 PM

I'm not sure what the official name is, but I'm referring to the server header (e.g.: Apache/1.3.29 (Unix) mod_perl/1.29 PHP/4.4.1 mod_ssl/2.8.16 OpenSSL/0.9.7g). Services like netcraft allow you to see them. What linux app would I use to find these server headers? Thanks.

You can use this utility to identify a web server. However, keep in mind that many people specifically alter the response to foil hacking attempts (many Linux Apache site respond as Windows IIS, for example).

Under firefox there are at least 2 nice extensions:
-> Live HTTP headers
-> Header Spy

For a tool, probably netcat is enough to do this, connect to port 80 of the server and try something like this:
POST X HTTP/1.0
TRACE X ..
