Hey All..

I'm following up on this thread after lots of different configuration attempts, reinstalling apache2 from source, more configuration attempts, banging my head against the wall, and endless troubleshooting.. Unfortuantely I am still failing to configure this correctly.

Thankfully the people using my apache as a open proxy are so relentless I only need to start apache for a few seconds to determine if the proxy is still open or not...

So... I've made quite a bit of progress, but I am still at a loss to understand what is going on here.... Possibly this is a question for the apache forum, but I figured some of my fellow zope users might be able to help, since all I'm using apache for is to rewrite for zope, and log access.

I have cleaned up my virtual host directive to only use a single Rewrite Rule (which works): RewriteRule ^/(.*)$1 [L,P]

Still the proxy was open and under attack.

I turned off mod_proxy and related proxy modules... But... The P flag in the RewriteRule uses the proxy module though, so the rewrite did not work.

I tried removing the P flag, and it does redirect to the appropriate page, but does not rewrite the URL correctly.

I have tried using all of the following (inside the virtualhost directive, outside of it, and both) to disable the open proxy... none of which have any effect:

<Directory proxy:*>
Order Deny,Allow
Deny from all
Allow from www.myserver.net

ProxyRequests Off

I attempted to use

ProxyBlock *

Which was effective, but also killed the rewrite rule.

Can anyone offer me a decisive way to kill off this open proxy?

I'm getting so frustrated with it I'm considering just ditching apache entirely and running zope on port 80. of course this would mean no virtual hosts, but I can live with that in this case.

Please help!

I abandoned mod_proxy for mod_rewrite. Security-wise, mod_rewrite had
less to worry about (this is important when website administration
changes hands).

The sample configuration below shows how to handle Zope resource
quirks and how to proxy requests to and from folders in Zope (both
tested). The last rule is my guess at what "proxy everything to and
from Zope" would look like (untested). Apache is listening on 80 and
routes requests to a Zope instance listening on 8080.

<IfModule mod_rewrite.c>

    RewriteEngine On
    RewriteLog "/path/to/rewrite_log"

    # Zope serves some system-ish content from p_ and misc_.
RewriteRule ^/p_(.*){HTTP_HOST}/VirtualHostRoot/p_$1 [L,P] RewriteRule ^/misc_(.*){HTTP_HOST}/VirtualHostRoot/misc_$1 [L,P]

    # Apache folders served by Zope folders.
RewriteRule ^/folder1(.*){HTTP_HOST}/VirtualHostRoot/folder1$1 [L,P] RewriteRule ^/folder2(.*){HTTP_HOST}/VirtualHostRoot/folder2$1 [L,P]

    # Push everything to Zope?
RewriteRule ^(.*){HTTP_HOST}/VirtualHostRoot/$1 [L,P]

Subject: [Zope] apache open proxy configuration problem

I've been running zope through apache for years and years now, and I
have a new machine set up with apache 2.0.48 and zope (Zope 2.8.0-final,
python 2.3.5, linux2)

Using Identical Vhost configuration settings from an old machine all has
been well, up until about 5 days ago, when I noticed the machine getting
slammed, and wierd logs started showing up like:

xxx.xxx.xxx.xxx - - [14/Oct/2005:14:09:06 -0700] "GET
http://partners.mygeek.com:80/search.jsp?partnerid=98885&pagesize=12 <http://partners.mygeek.com:80/search.jsp?partnerid=98885&pagesize=12>
HTTP/1.1" 403 406

(IP removed to protect the guilty)

In my quick research to try to determine the problem, I found people
advising to turn "ProxyRequests Off", which I did, but did not have any

Luckily this is just a development server, not a live production server,
so its not super critical, but I'm nervous now that my production server
might be in the same state...

Here is a sample vhost.conf entry:

ServerName www.greengraphics.net
ServerPath /var/www/greengraphics/www
DocumentRoot /var/www/greengraphics/www
ServerAdmin webmaster
RewriteEngine On
TransferLog logs/Vhost-greengraphics-access.log
ProxyRequests Off
        <Proxy *>
                Order deny,allow
                Allow from all
ProxyPass /
ProxyPassReverse /

mod_proxy.conf looks like:

  <IfModule !mod_proxy.c>
    LoadModule proxy_module             modules/mod_proxy.so
    #LoadModule proxy_connect_module    modules/mod_proxy_connect.so
    #LoadModule proxy_ftp_module        modules/mod_proxy_ftp.so
    LoadModule proxy_http_module        modules/mod_proxy_http.so

<IfModule mod_proxy.c>

# Proxy Server directives. Uncomment the following lines to
# enable the proxy server:

ProxyRequests Off

<Proxy *>
    Order deny,allow
    Deny from all
#    Allow from .your-domain.com

# Enable/disable the handling of HTTP/1.1 "Via:" headers.
# ("Full" adds the server version; "Block" removes all outgoing Via:
# Set to one of: Off | On | Full | Block

ProxyVia On

# End of proxy directives.


any suggestions?  places to look to verify security?
