How do I start or restart RHN Proxy Server?
Resolution:
You can start or restart the RHN Proxy Server by starting or restarting the Apache, Squid, and RHN Auth Cache Daemon with the following commands: 

[root@rhnproxy root]# /sbin/service httpd restart
Stopping httpd:                                            [  OK  ]
Starting httpd                                             [  OK  ]
[root@rhnproxy root]# /sbin/service squid restart
Stopping squid:                                            [  OK  ]
Starting squid:                                            [  OK  ]
[root@rhnproxy root]# /sbin/service rhn_auth_cache restart
Shutting down rhn_auth_cache:                              [  OK  ]
Starting rhn_auth_cache:                                   [  OK  ]


If you wish to check that the services are running you can use the status option instead of restart.

You can also use ps and netstat output to see if the associated applications are running. A typical RHN Proxy server will show something similar to the following when checking for these services:
