CONCLUSION: the vbuzzer works anywhere as long as there is an proxy(http, SOCKS4,5).

647i(六不一没有)

the http proxy need to support GET and CONNECT menthod. The CONNECT method should support port 5223(which is used for vbuzzer, other than 443 which is well-known https port).

Currently,I have a proxy with features mentioned above enable, if you are using vbuzzer outside north america, you can use it for your call. To avoid abuse, I have close proxy port 443.

you can find out my proxy server address from my other posts -- if you really need it.

AGAIN: the reason why a proxy is needed is the vbuzzer server drop the connection which is from China ( I thought it is IP based, and setup at at TCP and up level). So, a proxy will work, and I have approved it.

Have fun.

工作学习 / 专业技术讨论 / vbuzzer doesn't work in China. apache gurus' help is needed. -647i(六不一没有); 2005-6-11 {2786} (#2340862@0)
本文发表在 rolia.net 枫下论坛just did a test with friend in China, who is vbuzzer user.

vbuzzer doesn't work. aftrer use ping and tracert in china, I found that the vbuzzer client is able to estiblish tcp connection to server but is disconnect by server right away after it found out the connect is from China.

the conclusion is vbuzzer block the ip from the server side but not the ip level. (both client in china and toronto are able to estiblish tcp connect with the vbuzzer server: by ping and telnet vbuzzer.com:5223)

The solution is let vbuzzer server recognize the china vbuzzer client as it is in toronto: use apache2 proxy

the china client is use my apache2 server as proxy:
69.199.166.147:80

the following is my conf of apache2:
===============httpd.conf========
ProxyRequests On
ProxyVia On

<proxy *>

QUESTION:
what should I do to allow the "CONNECT" command to go through my web server as proxy to connect to vbuzzer.com?

Thanks更多精彩文章及讨论，请光临枫下论坛 rolia.net

the apache server i am using is apache 2.0.49 on Suse 9.x 2.6.4-52 Thanks for your help, if we can solve the problem, the free v-buzzer can be used in china :) -647i(六不一没有); 2005-6-11 (#2340870@0)
shoot, didn't know what is vbuzzer , so I did a google, then all a sudden I heard some buzz, thought there was a fly behind my computer :-( -holdon(again); 2005-6-11 {200} (#2340923@0)
Why don't you install a socks 5 proxy ? That will for sure work. about apache, I didn't try it, but looks like you need another module:

http://httpd.apache.org/docs-2.0/mod/mod_proxy_connect.html

1. the free version of v-buzzer is an ip phone (software version) with a toronto phone number. 2. I have added line "mod_proxy_connect " to loadmodule file, but -647i(六不一没有); 2005-6-11 {89} (#2340930@0)
each time when I restart the apache, the line is removed automaticly. :(

feel confuse.

you mean apache will automatically modify the conf file? that's quite unbelieveble. -holdon(again); 2005-6-11 (#2340943@0)

ok. found it, in this version the content of the loadmodule will be automatic copied from a another file in systemconfig folder. But, when the https always get 403!! -647i(六不一没有); 2005-6-11 {1273} (#2340973@0)
本文发表在 rolia.net 枫下论坛here is the config file:

is there any other thing I need for https CONNECT method to go through?

here is apache log:

==============
from the log above, we can see the GET method for http is OK. but the CONNECT method for https doesn't work, both to vbuzzer.com and ctfs.com.

Any idea?更多精彩文章及讨论，请光临枫下论坛 rolia.net

if you only AllowCONNECT 443, that means only 443 port accept connect mothed, right? try allowCONNECT 443 80 -holdon(again); 2005-6-11 (#2340979@0)
