Hi Team,

I am working with a client and ran into this problem....

They have a rhel6 box behind IIS web proxy using NTLM auth. We recently discovered that there is no internet connectivity so they provided me with a proxy to use to bypass it. I tried the below,

export http_proxy="http://user:pass@proxyserver:port"

This does not seem to be working.

Our goal is to register this box with rhn and then use yum to update the system with the latest patches. rhn_register did not work as it says "we can't connect to https://xmlrpc.rhn.redhat.com/XMLRPC' - make sure that the internet connection on this system is operational"

We can't go further. we then googled and got some responses that rhn_register does not work well with IIS proxy and NTLM authentication and they asked us to use a third party program called ntlmaps.sourceforge.net. We then downloaded the package and configured it by entering proxy details in server.cfg file and then run ./main.py

It is now listening on a port localhost 5865....

we then used this command it works

rhn_register --proxy=http://localhost:5865

It is now connected to the rhn site and registered the box successfully.

we then tries to use yum update or yum install httpd it gives below error;

yum install httpd
loaded plugins: dellsysidm product-id, refresh-packagekit, rhnplugin, security,subscription-manager
updating certificate-based repositories
unable to read consumer identity
Error: failed to retrieve repodata/25273acb31.......primary.xml.gz from rhel-x86_64-server-6
error was [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 407"

We can't install any packages and we tired below steps,

yum clean all
rm -rf /var/cache/yum*
adding below to the /etc/yum.conf
proxy=http://localhost:5865
ftp_proxy=http://localhost:5865

nothing works... can someone please shed some light on this?

Thanks
SA
