firewall

nixCraft: "This Linux based firewall is controlled by the program called iptables to handles filtering for IPv4, and ip6tables handles filtering for IPv6."

Shawn shows us how to set up a quick SSH tunnel for accessing a computer behind a remote firewall.

He demonstrates this from his hotel room 400 miles away from his home network!

Geek.com: "The issue reported was the fact Sony was running PSN on a server that had an outdated version of Apache and no firewall in place.

That meant any vulnerabilities known about for that version of Apache, and patched in more up-to-date releases, were easy to take advantage of."

The H:"The addition of ipset support makes it easier to run a firewall, as it means that only one table needs to be modified in order to block a specific IP address."

The Amazon Kindle 3G allows users to view any webpage in the world on a six inch monochrome screen. That doesn't sound too impressive, unless you are in China.

See, it’s not the display that’s of interest here: it’s the “any webpage” part. That’s because the device apears to have circumvented the infamous “great firewall of China” filter.

China's Web-censorship regime may be formidable, but ordinary Chinese are learning to scale it a little at a time.

Can the authorities hold them back?

Distrowatch: "Manuel Kasper has announced the release of m0n0wall 1.3, a minimalist firewall distribution based on FreeBSD: "After almost three years in beta, I have decided that m0n0wall 1.3 is now good enough for production."

EnterpriseNetworkingPlanet: "Now we'll open the CentOS firewall and configure our access points (APs). Then we'll distribute the CA file to all the computers and configure them with the encryption and authentication settings.

Plus we'll set up SQL so you can store your user and AP information in a database rather than text files."

BeginLinux: "This course will show you how to build a bridge firewall or “stealth firewall” using ebtables and iptables.

This is an easy process and works on older or lightweight machines as you will see it uses Mini-ITX technology."
