problem in first usage of nginx

[Yanxin Zhang]

Hello,
I have several questions about using NginX.

1)
After I first install nginx-0.8.41 in Ubuntu 8.04 system, with the default
.conf file.
I start nginx with 127.0.0.1:8000, however, I can not see the default
webpage. The browser can not connect to server.
Could anyone help me to figure it out?

2)
I am following the instructions in
http://wiki.nginx.org/HttpChunkinModule

to configure nginx.
when I start nginx, I encounter the error:
[emerg]: unknown directive "chunkin" in ./conf/nginx.conf:36

The line is
 35     server {
 36         chunkin on;
 37         listen        127.0.0.1:8000;


Thanks,
Yanxin
