HOWTO: disable IPv6 networking in Debian
IPv6 is ready?
Tonight I did ran netstat (`netstat -plunt`) on my Debian server and saw that I had some ports listening via IPv6. It’s a shame IPv6 hasn’t caught on as it’s better than IPv4 in virtually every way, and it should, especially since TCP/IPv4 was standardized in ARPANET RFC’s… in 1981! Also, IPv6 provides network level security via IPSec, which enables authentication of sender and encryption of communication path, to secure communications, all fun stuff, but while some point to the fact that the Beijing Olympics used IPv6 exclusively as a point in how far it’s come, that’s hardly saying much when the protocol went Alpha… in 1996! I mean I put things off and get distracted, sure, but come on! So while its adoption can be argued to be a case of the chicken before the egg, since I’m not using anything IPv6, nor do I or my ISP even have the capability to use it, it’s silly and perhaps dangerous to leave it running with open ports. So, if you’re not using it, disable it – it’s easy, just put on your pointy hat and follow along… (more…)

I enjoy learning by doing, painting infrequently and listening to more music than the law allows. Feel free to follow me and comment on my thoughts and ideas; we're all in it together kid.
