Hello people, I know I’ve been absent for a while and I’m sorry about that. Then again, its not like I have legions following me, so my guess is no one has really noticed :) Anyway, I have a nice few posts coming up. Particularly one regarding a small “fork” or mod of intel’s igb NIC driver that allows parallel traffic capture from several processes from userspace with zero-copy and avoiding skbuff overhead. But I don’t want to get ahead of myself, that will be coming up, together with the github(most likely) repo and explanation.

This post is really nothing special, I just hope it can help some gentoo users like myself. My ISP recently changed my service from fixed ip to dynamic ip (yup, I somehow managed to keep a fixed IP address for something like 8 years). So my dyndns.org account needs a constant update of the DNS records. They suggest two alternatives ddclient and inadyn, and as you can see in their links, they provide some decent literature and even config file generators, not bad. I went for ddclient, a perl based client. Ddclient comes ready with init script for debian, fedora, ubuntu,… users. But as you may know, gentoo users are not as common. Furthermore, init scripts are a little different in gentoo (I think in this case different is better). I want the ddclient daemon to start automatically at startup, so I needed/wanted the corresponding init.d gentoo script. I quickly hacked one up. Enjoy.
