[rhel-5] yum through http proxy
We are using several Red Hat Enterprise 5 servers in a DMZ which are only able to communicate with internet through an HTTP proxy. The machines are registered (with rhn_register), the logs show that the up2date authentication is successfully retrieved and the proxy access correctly configured. If it wasn't, I wouldn't be able to register.
My problem is that I cannot do the updates with yum... The proxy is only for HTTP and not HTTPS. So I tried to use the workaround in the conf file /etc/sysconfig/rhn/up2date with the "noSSLServerURL" option.
I checked the logs on the proxy server and it receives the requests but they are always on https and so they cannot go through. I always get the yum error message because of the impossible communication :
Error: Cannot open/read repomd.xml file for repository: rhel-i386-server-5
With rhel-4, we had a lot of other parameters to configure up2date. Now with yum, it's more restrictive.
Any idea ? It's important for us to be able to perform updates on those servers in the DMZ. Please help !
