Configure HTTP Proxy (optional)

One-liner Command

subscription-manager config --server.proxy_hostname=proxy.example.com --server.proxy_port=8080 --server.proxy_user=admin --server.proxy_password=secret

Alternatively, proxy information can be added into configuration

/etc/rhsm/rhsm.conf:

# an http proxy server to use
proxy_hostname =

# port for http proxy server
proxy_port =

# user name for authenticating to an http proxy, if needed
proxy_user =

# password for basic http proxy auth, if needed
proxy_password =

Testing the connectivity to RHN

Without Proxy

curl -v https://subscription.rhn.redhat.com/subscription/ --cacert /etc/rhsm/ca/redhat-uep.pem

With Proxy

curl -v --proxy-user user:password --proxy proxy.example.com:8080 https://subscription.rhn.redhat.com/subscription/ --cacert /etc/rhsm/ca/redhat-uep.pem

curl -v --proxy-user user:password --proxy proxy.example.com:8080 https://subscription.rhsm.redhat.com/ --cacert /etc/rhsm/ca/redhat-uep.pem

curl -v --proxy-user user:password --proxy proxy.example.com:8080 https://cdn.redhat.com/ --cacert /etc/rhsm/ca/redhat-uep.pem
