Quite. Disabling sendmail (even if done properly and completely) should not have any effect on the functioning of your basic networking setup. There has to be something else going on here. > There have been some changes to the syntax used to configure IPv6 > addresses in 9.0 -- check rc.conf(5) for details -- but that doesn't > seem entirely relevant here. Hmmm... how about showing us your > rc.conf to see if we can spot any problems? As Matthew suggests, try rebooting and see what happens. Send your dmesg output and rc.conf to the list so we can get a clearer picture of what's going on. Best of luck, Conrad -- Conrad J. Sabatier conrads@cox.net
