Basically I'm nearly done setting up an LTSP Server and I want to make sure that no one who logs on can fiddle with the settings.  I've got Tinyproxy and Dansguardian installed and working but only if I manually specify the proxy settings.  I found something about entering some settings in /usr/lib/firefox/firefox.cfg which I have entered (details here: <a href="http://m.linuxjournal.com/article/9044" target="_blank">http://m.linuxjournal.com/article/9044</a>) but I'm finding I can enable and disable the Firefox proxy settings and alter the rest of the settings as I please. I did try Firehol to force the proxy transparently but it stopped the LTSP clients from booting unless I enabled a whole lot of ports on the Firehol configuration (I got so far but got stuck on the nbd ports). Just wondering if anyone knows how to do this? Ta, Rob </blockquote><div> Hiya Rob, I've not tried locking down FF before but I did jot down some documentation about how to set up a transparent proxy for a community wireless network. The same should apply to your LAN too. Go to <a href="http://www.justuber.com/publicwifi:public_wireless_internet_access">http://www.justuber.com/publicwifi:public_wireless_internet_access</a> and check out the transparent proxy bit. As I recall, it lets traffic on any other than port 80 go on to it's destination, but redirects port 80 through the content filtering. Chris </div></div>
