Which is correct? I assume the latter? Yes, the message should have read "Enable sending router advertisments". Sorry, the exact opposite came out - the naming does my head in :-/ > > Enabling accept_rtadv should prevent rtadvd from sending RAs on the > interface, so disabling it is a necessary step if one wants to send > RAs. > > However, accept_rtadv is off by default in the current rc.d > framework. Why forcibly disabling it is needed? After upgrading from 8-STABLE to 9-STABLE on Monday, IPv6 routing advertisments were broken. Disabling accept (enabling send) appeared to be necessary to get things up and running. As you say, net.inet6.ip6.accept_rtadv is set to zero (off, meaning that we *can* send advertisments), so I don't now what the issue is. Irrespective of this, I think it's useful to explicitly set the interface to be able to send advertisments when running rtadvd - just in case the sysctl is set to 1 elsewhere. Doing an "ifconfig inet6 accept_rtadv" after boot doesn't seem to disable sending advertisments, so I'm finding it difficult to test this remotely... testing is awkward when I'm not at home as this machine is also suffering from the "can't reboot" issue!! I'll look into why the sysctl doesn't seem to behave as expected when I get home this evening. -- Brian Somers Don't _EVER_ lose your sense of humour !
