Description of problem: Web-UI is not responsive on the start pages. Version-Release number of selected component (if applicable): 4.0 How reproducible: Always Steps to Reproduce: 1. Open Web-UI in browser 2. 3. Actual results: You need to wait a long time until the start page with the list of the systems is loaded. Expected results: The page should load much faster, especially since its access from the same machine. Additional info: Problem is probably caused by the "phone home" features of redhat-certification. The host running the web server is an isolated machine inside a laboratory infrastructure with practically no access to the outside internet. A wireshark trace reveals that the machine is trying to connect to hardware.redhat.com (and probalbly other sites). This and adding that the firewall that prevents access to the internet has a DROP rule for forbidden connections (instead of REJECT) will proabably make the whole process wait until some timeouts for the connections expire. Solutions? Is there any "offline" config option that I can set to prevent trying to access the Internet at all? Would it help to setup a firewall rule on this system that REJECTS all connection attempts to the internet, but allows connections to the 10./8, 172.24./12 and 192.168./16 networks?
Update: Installed some iptables rules that blocks all outgoing traffic with destinations that aren't private IPv4 adresses with "REJECT". Now the machine running the Web-UI gets an icpm-host-unreachable every time it wants to phone home and response times went down to less than a second. ;-) So I close this with "worksforme".
