firewall

Linux.com: "Firewall Builder (fwbuilder) is a graphical application that can help you to configure IP traffic filtering.

It can compile the filtering policy you define into many specifications, including iptables and various languages used by Cisco and Linksys routers.

Separating the actual policy you define and the implementation in this way should let you change what hardware is running your firewall without having to redefine your policy for that platform."

Privacy has always been a major concern for BitTorrent users and there are only a few ways to remain anonymous.

We all know about the "Great Firewall" of China that's designed both to keep certain website inaccessible from China, but which is also supposed to block certain content in China from reaching the outside world.

While there already are some questions about how effective the Great Firewall really is, it does seem odd that the majority of "badware" sites are all hosted in China.

We've heard this argument plenty of times in the past, but a recent study suggests that 85% of people surveyed in China are perfectly fine with the Great Firewall, saying that they believe the government has a responsibility to "protect" them from dangerous content.

Of course, this is always how the government has positioned the filter: not as "blocking" content it doesn't like, but as protecting citizens from "dangerous" content.

Get the feeling that folks in Russia are a bit jealous of China's Great Firewall?

If you've administered any remote Linux machines then you are already familiar with SSH, but you might not know that you can use SSH for much more than just connecting to a shell on a remote system.

By using SSH's port forwarding features, you can set up encrypted tunnels for many services, or connect to systems behind a firewall from home.
