Linux Mint Forums

Just read this http://www.theinquirer.net/gb/inquirer/ ... ar-present

I just ran the test, and there is no IPv6 connection open on my Mint 5 laptop.

However, this raised an interesting point. Is Linux by default has open to attack IPv6 connectivity or protected if IPv6 is enabled?

Once IPv6 is enabled (assume this is the future standard, we have no choice but use it), what is the best practice to ensure the safety of system?

By the way, is there any "default" firewall in Mint? I always use a software firewall for Windows, but not sure about Linux. Any suggestion to a good, easy to config firewall for Linux? My computers are always connected behind router.

The file specified in /etc, I just couldn't find it, am I missing something?

I did not read the article in the link - just a quick glance
Mint has IPv6 disabled by default - that's why you see a warning about it if you have a verbose boot.
The subject of firewalls is a bit different from Windows
All (?) Linux distributions have iptables (google for it to get more information) and the applications called firewalls are just some GUI to iptables. Debian based distributions (or at least Ubuntu) have ports closed to the outside by default. So if you are behind a router (which normally has a firewall) you don't have to do anything
