Work with HTTP Proxies

For Swisscom RHEL VMs, no predefined proxy configuration is in place. Configuring the Operating System to use HTTP proxies can be done by setting standard environment variables. These are the NO_PROXY, HTTP_PROXY and HTTPS_PROXY environment variables. You can configure both an HTTP and HTTPS proxy for his purpose. Domains for which no proxying should be performed must be specified via the NO_PROXY environment variable.

This is an information message

Warning

When using a proxy in your environment, make sure to set the NO_PROXYvariable and exclude the domain .sccloudinfra.net

Example Proxy Configuration:

HTTP_PROXY=http://<ip_addr>:<port>/
HTTPS_PROXY=https://<ip_addr>:<port>/
NO_PROXY=.sccloudinfra.net

No proxy configuration in /etc/yum.conf

Do not set any proxy configuration in /etc/yum.conf. Otherwise, you will not be able to connect to the configured Red Hat repositories from Red Hat Satellite. Instead, place your proxy in your alternative repository file under /etc/yum.repos.d/.
