i´m not that crack and wondering where to put a little script into /var/chroot-pppoe/...../ip-up the automatically refresh my dynamic dns on refreshing ppp0.
Because I have a computer on the DMZ zone running, Ftp, Http, etc., and that computer is 24x24 online, I decide to install DDclient rpm on that machine, and configure the use of the asl http proxy on /etc/ddclient.conf. I do that, because I don't like to install anything on the Asl box.
