---Problem Description---
RHN yum plugin cannot connect to the IBM RHN Satellite over a HTTP Proxy
 
Contact Information = Christian Ambach / cambach1.com
 
---uname output---
Linux host 2.6.18-53.el5 #1 SMP Wed Oct 10 16:34:02 EDT 2007 i686 i686 i386
GNU/Linux
 
Machine Type = HS20
 
---Debugger---
A debugger is not configured
 
---Steps to Reproduce---
change the up2date config to use a http proxy
my settings in /etc/sysconfig/rhn/up2date:
enableProxy=1
httpProxy=proxy:80

With that configuration all RHN related applications fail to work and the proxy
complains about a bad HTTP request:
[Wed Feb 20 17:32:47 2008] [error] [client 1.1.1.1] client sent HTTP/1.1 request
without hostname (see RFC2616 section 14.23): /

Sample command outputs:

======================================================================================================
we were able to find a solution for this problem on:

http://adumont.serveblog.net/2008/02/07/rhel5-yum-proxy-error/


which basically says  The solution is to edit
/usr/lib/python2.4/site-packages/M2Crypto/httpslib.py in the machine and add the
following line, between lines 165 and 166

 msg = msg + "Host: %s:%d\r\n" % (self._real_host, self._real_port)

The code will then look like this: 

def <em>get</em>connect_msg(self):
        """ Return an HTTP CONNECT request to send to the proxy. """
        msg = "CONNECT %s:%d HTTP/1.1\r\n" % (self._real_host, self._real_port)
        msg = msg + "Host: %s:%d\r\n" % (self._real_host, self._real_port)</b>
        if self._proxy_auth:
            msg = msg + "%s: %s\r\n" % (self._AUTH_HEADER, self._proxy_auth)
        msg = msg + "\r\n"
        return msg

I also found similar bugs on Redhat Bugzilla on :

https://bugzilla.redhat.com/show_bug.cgi?id=208852

However this errata refers to yum-rhn-plugin-0.5.2-3.el5, and our  installed version is 
yum-rhn-plugin-0.5.2-5.el5_1.2  which is newer. I also checked the Knowledge base and was able to
find asimilar error

http://kbase.redhat.com/faq/FAQ_49_10220.shtm

Redhat, we were wondering if this fix will be included in Redhat Enterprise Linux version 5.2.

Thank you.
