O criar um firewall e compartilhar conexão usando IPtables. Carlos E. Morimoto criou 9/jul/2007 às 11h00 Todo administrador de redes aprende logo que uma das coisas mais importantes para qualquer rede é um bom firewall.
Embora existam muitos mitos em torno disto, os firewall não fazem milagres, apenas adicionam uma camada extra de proteção, escondendo as vulnerabilidades das máquinas. Você pode ter um servidor IIS ativo com todas as vulnerabilidades possíveis dentro da sua rede, mas ninguém poderá fazer nada se não conseguir se conectar a ele. Este é o papel do firewall, limitar e filtrar os acessos aos servidores e estações de trabalho da sua rede. Existem vários tipos de firewall, de todos os preços. Outro ponto comum é a necessidade de compartilhar a conexão com a Web. Isso pode ser feito facilmente através do Iptables. Existem vários programas gráficos para configuração de firewalls, como por exemplo o GuardDog e o Shorewall (usando no Red Hat e Mandrake). Antes de mais nada você precisa verificar se o pacote do iptables está instalado. Apt-get.org.

I have also seen graphical representations of the Web of Trust for a specific public keyring, and I've always been curious how I could create my own. Well, last night I finally buckled down and figured it out. So, hopefully, this will be of interest for some. In case you're curious, this is what I'm talking about. First, make sure you have the gnupg, sig2dot, graphviz and imagemagick packages installed.
First, the sig2dot package just provides a single Perl script that reads signatures in an OpenPGP/GPG keyring, and creates a "dot" file. So, here's the commands in order that are needed to create your graphical web of trust. . $ gpg --list-sigs --keyring ~/.gnupg. This should take a bit, depending on the size of your pubring.gpg file. . $ gpg --list-sigs --keyring ~/.gnupg. You'll notice that I'm saving the STDERR output to "~/.gnupg/pubring.error.txt".
