Back on the Linux wagon

I have and do run Linux from time to time, and primarily have been partially interested in features available in Linux. My interest comes in cycles; back in 1995-98 I used to run snapshot kernels and custom tweak everything. Then I learned about BSD, become a huge OpenBSD fan, and totally ditched Linux.

With virtualization being built on Linux and the primary development of applications being based on a Linux environment, I have started digging back into it.

Now I am getting OpenStack/DevStack running on Ubuntu 12.04 with an early build. This should be fun.

comment spam via ipv6

Checking some logs I realized that comment spam was originating from a host in Japan at: 2001:2e8:626:0:2:1:0:b7.

With the plethora of IPv6 addresses, it will only be a matter of time before we see massive comment/email/and web spam originating from IPv6 address blocks.

And what exactly is this machine that is sending comment spam?

Why, it’s a default install of Centos with a bunch of open ports. I am sure some not-so-friendly scripts have found their way inside this vulnerable host and have started using it to generate spam. The fact that the machine was IPv6 connected was likely a coincident, but a useful one (to the spammer).

I have now blocked the /64 of that range to prevent such annoyances.
