firefox settings for pickup cfg file

On December 31st, 2006 Manfred (not verified) says:

Hi,
Nice article!

I have a non-preloaded firefox 1.0.7 on my distribution (slack).
I had to change/augment the greprefs/all.js file
pref("general.config.obscure_value", 0); //was 13 ; changed pref("general.config.filename", "firefox.cfg"); //Added
otherwise the firefox.cfg file would not be read.

Manfred.

Using iptables

On October 23rd, 2006 Darryl Scroggins (not verified) says:

I wanted a filtering system that would not be easy to defeat and I did not want the solution to depend on one machine being on all the time.

I ended up running dansguardian, squid, and iptables on each machine, using iptables to forces the browser to use the squid proxy at 8080.

The following line, added to the end of /etc/rc.d/rc.local, does the trick:
iptables -A OUTPUT -p tcp --dport 80 -m owner ! --uid-owner squid -j REJECT --reject-with tcp-reset

This configuration has served me well for over a year.

If last month's Infrastrucuture issue was too "big" for you then try on this month's Embedded issue. Find out how to use Player for programming mobile robots, build a humidity controller for your root cellar, find out how to reduce the boot time of your embedded system, and if you're new to embedded systems find out the basics that go into one. You can also read about the Beagle Board, the Mesh Potato and a spate of other interestingly named items. And along with our regular columns don't miss our new monthly column: Economy Size Geek.
