firefox settings for pickup cfg file

Manfred's picture

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

Darryl Scroggins's picture

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.

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
