Lighttpd、Nginx 、Apache 隐藏响应头信息的Server信息,apache和php的版本信息
web服务器的版本信息

一、隐藏Apache信息
默认情况下,很多Apache安装时会显示版本号及操作系统版本,甚至会显示服务器上安装的是什么样的Apache模块。这些信息可以为黑客所用,并且黑客还可以从中得知你所配置的服务器上的很多设置都是默认状态。

这里有两条语句,需要添加到httpd.conf文件中:

ServerSignature Off

ServerTokens Prod

ServerSignature出现在Apache所产生的像404页面、目录列表等页面的底部。ServerTokens目录被用来判断Apache会在Server HTTP响应包的头部填充什么信息。如果把ServerTokens设为Prod,那么HTTP响应包头就会被设置成:

Server:Apache

二、隐藏PHP信息
修改php.ini

将expose_php On
改为
expose_php Off


参考解决方案:
1. Lighttpd 1.4.20
src/response.c:108 改为:
buffer_append_string_len(b, CONST_STR_LEN("Server: jufukeji"));
输出 Header:

HTTP/1.1 404 Not Found
Content-Type: text/html
Content-Length: 345
Date: Mon, 12 Jan 2009 13:54:02 GMT
Server: jufukeji

2. Nginx 0.7.30
src/http/ngx_http_header_filter_module.c:48-49 改为:
static char ngx_http_server_string[] = "Server: jufukeji" CRLF;
static char ngx_http_server_full_string[] = "Server: jufukeji" CRLF;
输出 Header:

HTTP/1.1 200 OK

3. Cherokee 0.11.6
cherokee/version.c:93 添加:
ret = cherokee_buffer_add_str (buf, "jufukeji");
return ret;
输出 Header:

ap_add_version_component(pconf, "jufukeji");
return;
输出 Header:

Server: jufukeji

6. Tomcat 6.0.18
java/org/apache/coyote/http11/Constants.java:56 和 java/org/apache/coyote/ajp/Constants.java:236 均改为:
ByteChunk.convertToBytes("Server: jufukeji" + CRLF);
输出 Header:

Server: jufukeji
ETag: W/"7857-1216684872000"

将编译所得 jbossweb.jar 覆盖 JBoss 编译输出文件:
