Problem solved. I installed a complementary Java Based Offline Proxy Server… [url]http://www.proxy-offline-browser.com/[/url]
(Java was bundled in Ubuntu) proxy ip 127.0.0.1 and port 8080 in Fog configuration and Firefox settings
I consider Fog to complex to be modified according to my wishes. It is clearly built to be online. To much work

Thank you for your reply. Sorry i didnt provide information enough. Fog version 1.2.0 Ubuntu 14.04.1 server (i.e last versions)
I installed according to Wiki: “install on isolated network” ==>only DHCP service activated.
I have searched google, forums and wiki. This thread is all i found.
I have tried to comment out in /var/www/fog/management/index.php but it is restored at restart.
(My attempts there was the only contributions to error.log)
I do have considered a Proxy Server. But i havent done that before. Is the proxy supposed to be connected to the internet?
(I am not allowed to interfere with our intranet) Or can I use cached data?
The problem is obviously Fog polling info to administrator page. Instant access to login etc as soon as i connect to inet
This info cant be crucial. Apart from time out issue Fog functions without inet.
There must be some way to comment out proper parts of code… if i can find the right document… I think… I hope… I beg

Im also running fog in an isolated environment to avoid interfering with with our severely restricted intranet.
Fog is polling expendable? internet info on login, configuration… plus pinging hosts for name resolution.
This times out eventually. But annoying and time consuming. I have solved pinging nameserver issue but internet polling issues remains. Which text (page) is to edit. Is there any easy solution. Or is it line by line editing. Please help
