Thanks for looking! I'm running Ubuntu 10.10 server on a mixed static & dynamic network. My router is running radvd to handle IPv6 addressing for temporary devices. This Ubuntu server has a static IPv6 address. The problem is, it is picking up an address from radvd no matter what I do. I have combed through Google to little avail. I have put the following lines in /etc/sysctl.conf:
net.ipv6.conf.all.accept_ra = 0
net.ipv6.conf.all.autoconf = 0
... but that doesn't seem to stop it from accepting addresses from radvd. If I delete the dynamic address, it shows back up within a few minutes. If I reboot the box, it is still there as well. I'm missing something here, but I don't know what! Thanks for your help!
