OpenBSD 自带httpd显示来访者ip的脚本配置问题

[f5b]

就是利用OpenBSD 5.6或以上系统的httpd服务器上面弄个页面，任意浏览器访问这台服务器，就自动显示来访者的ip地址

效果类似 访问 http://checkip.amazonaws.com/

完整的配置方法有么？

涉及到chroot slowcgi 等，可供参考的文档如下，当作备忘吧，若没有人回复，将来有时间继续研究。。。

搞定了，自问自答
-----
OpenBSD显示来访者ip地址和浏览器信息的脚本

编辑脚本
# vi /var/www/cgi-bin/test

#!/bin/sh
echo "Content-type: text/plain"
echo
echo $REMOTE_ADDR
echo $HTTP_USER_AGENT

设置脚本可执行权限
# chmod 0555 /var/www/cgi-bin/test


# ldd /bin/sh
/bin/sh:
Start End Type Open Ref GrpRef Name
000019c10e34a000 000019c10e7cb000 dlib 1 0 0 /bin/sh


在chroot相应目录添加需要的程序
# cp /bin/sh /var/www/bin/


确定程序可执行
# ls -l /var/www/bin/sh
-r-xr-xr-x 1 root daemon 480960 Mar 26 15:04 /var/www/bin/sh


添加恰当的http.conf
# cat /etc/httpd.conf


ext_addr="*"

server "default" {
listen on $ext_addr port 80

location "/cgi-bin/*" {
fastcgi

# The /cgi-bin directory is outside of the document root
root "/"
}

root "/htdocs"
}


添加必须的启动项
# cat /etc/rc.conf.local
httpd_flags=""
slowcgi_flags=""

启动
# /etc/rc.d/slowcgi start
# /etc/rc.d/httpd start

任意浏览器访问服务器
http://A.A.A.A/cgi-bin/test

得到结果
B.B.B.B Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko
